Early identi cation of stomal ischemia or infection (from changes in normal bowel ora) provides for timely interventions to prevent serious complications. Ulcerated areas on stoma may be from a pouch opening that is too small or a face plate that cuts into stoma. In clients with an ileostomy, the effiuent is rich in enzymes, increasing the likelihood of skin irritation. In clients with a colostomy, skin care is not as great a concern because the enzymes are no longer present in the effiuent. Use soap only if area is Maintaining a clean and dry area helps prevent skin break covered with sticky stool. Measure both width and size of the appliance must be altered to ensure proper t, length of stoma. Adequate adhesive area prevents the skin base of the stoma, with adequate adhesive barrier to apply barrier wafer from being too tight. A transparent appliance during the rst 4 to 6 weeks allows easy observation of stoma without necessity of removing pouch and irritating skin. Note: Sigmoid colostomy may not require an appliance if elimination is regulated through irrigation. Empty, rinse, and cleanse ostomy pouch on a routine basis, Frequent changes of the adhesive barrier wafer are irritating to using appropriate equipment.

Client may nd it easier to deal with an ostomy done to correct long-term disease than for traumatic injury, even if ostomy is only temporary. Also, client who will be undergoing a second procedure to convert ostomy to a continent or anal reservoir, may possibly encounter less severe self-image problems because body function eventually will be "more normal. Remind client that it will comments made in a normal, matter-of-fact manner can take time to adjust, both physically and emotionally. Provide opportunity for client to deal with ostomy through Independence in self-care helps improve self-con dence and participation in self-care.

With the exception of clozapine (which is indicated for treatment-resistant schizophrenia) definition of organic brain disorders cheap 150mg lyrica overnight delivery, currently marketed antipsychotics appear to differ mostly in their safety profiles. Overall, the needs of the schizophrenia patient population are only partially met by currently available drugs. Most patients do not achieve full remission of schizophrenia symptoms, and current drugs are generally ineffective for negative symptoms and cognitive deficits of schizophrenia. Lumateperone 42 mg was demonstrated to be superior to placebo on the primary efficacy endpoint in two 4-week studies (Studies 005 and 301). Both of these studies are considered to be adequate and well-controlled investigations. Thus, the benefit is expected to be clinically meaningful for a substantial proportion of patients who receive the treatment. Of note, although the Applicant assessed 14-mg, 28-mg, 42-mg, and 84-mg doses in placebo-controlled efficacy studies, only the 42-mg dose was found to be efficacious. Although there are many antipsychotics approved for the treatment of schizophrenia, patients often require trials of numerous antipsychotics over the course of the illness before an optimal treatment is identified. Thus, having an additional antipsychotic in the treatment armamentarium provides some value to patients. The safety database included 1724 patients exposed to lumateperone, 811 of whom were exposed in the three placebo-controlled Studies 005, 301, and 302. The safety database included 329 patients exposed to lumateperone 42 mg for 6 months and 108 patients for 12 months, which were adequate durations of exposure to facilitate premarketing characterization of safety. The most common adverse reactions to lumateperone were somnolence/sedation, nausea, dry mouth, dizziness, and creatine phosphokinase increased. The most concerning potential safety concern for lumateperone, discussed at length in this review, was based on findings from nonclinical studies in dogs and rats that were attributed to exposure to aniline metabolites. Humans receiving lumateperone for up to 12 months did not exhibit adverse events suggestive of those observed in dogs and rats. Furthermore, the lack of quantifiable aniline metabolites in humans receiving 42 mg lumateperone, in conjunction with a plausible metabolic rationale of why anilines would accumulate in dogs and rats but not humans, provides additional support that the nonclinical safety findings are not relevant to humans. The safety concerns of lumateperone can be managed in the postmarket setting by labeling known and anticipated risks, postmarketing pharmacovigilance, and the conduct of postmarketing studies. In conclusion, considering the balance of benefits and risks that were observed in the development program, we recommend that lumateperone 42 mg be approved for the treatment of schizophrenia in adults. The totality of evidence on benefit (including consideration of the negative results from Study 302 and the lack of efficacy for doses other than 42 mg) suggests that lumateperone 42 mg is superior to placebo, but that it is unlikely to have any meaningful efficacy advantages over other drugs in its class. Additionally, the safety findings from human studies suggest that lumateperone is unlikely to have meaningful safety disadvantages over other drugs in its class. The nonclinical safety findings, if assessed as relevant to human exposure to lumateperone, would have been sufficient to shift the benefit/risk balance against approval; however, multiple lines of evidence suggest that the nonclinical findings are not relevant to humans. With the exception of symptoms and cognitive deficits of schizophrenia generally show little clozapine, currently available antipsychotics Current to no improvement from antipsychotic treatment. In general, being only partially met by currently available first-generation antipsychotics have a higher risk of extrapyramidal therapies. Most patients do not achieve full side effects than second-generation antipsychotics. Additional treatment options However, individual patients often require trials of numerous agents that target unmet clinical needs are needed. Having additional antipsychotic are frequently treated with adjunctive medications to target treatments in the armamentarium is valuable depression, anxiety, obsessions and compulsions, and side effects of to clinicians and patients. These interventions include cognitive behavioral therapy, assertive community treatment, supported employment, and social skills therapy. Specifically, lumateperone risperidone 4 mg, placebo); Study 301 (N=450; treatment arms: 42 mg was found to be superior to placebo on lumateperone 42 mg, lumateperone 28 mg, placebo); and Study 302 the primary efficacy endpoint in two 4-week (N=696; treatment arms: lumateperone 42 mg, lumateperone 14 mg, studies (Studies 005 and 301). In approved for the treatment of schizophrenia, Study 302, lumateperone 42 mg was not found to be superior to patients often require trials of numerous placebo on the primary efficacy endpoint (p=0. In addition, the antipsychotics over the course of their illness 84-mg, 28-mg, and 14-mg doses of lumateperone were not found to before an optimal treatment is identified. Based on post-hoc sensitivity analyses, the Applicant considers Study 302 to be a failed, rather than a negative, study. In real-world clinical use, patients with schizophrenia are frequently initiated on antipsychotic drugs in the hospital setting to treat the acute psychotic symptoms that led to the admission. For an antipsychotic drug that is effective acutely, continuation is generally recommended following hospital discharge to reduce the risk of relapse. A total of 811 patients with generally consistent with other atypical schizophrenia were exposed to lumateperone in the three placebo antipsychotics. Risk and Risk exposure recommended by guidance on the extent of population Management exposure to assess clinical safety for drugs intended for long-term the most concerning potential safety concern treatment of non-life-threatening conditions. This case was assessed as unlikely related to that the nonclinical safety findings are not lumateperone treatment because it occurred two weeks after the last relevant to humans. Only two treatment-emergent serious adverse events occurred in subjects receiving lumateperone in the 4 to 6 the known risks of lumateperone use can be week placebo-controlled studies: one case of convulsive episode in a managed by product labeling, and ongoing patient receiving lumateperone 28 mg who had pre-existing risk postmarketing pharmacovigilance will be factors, and one case of agitation secondary to psychosis in a patient important to monitor safety signals that were receiving lumateperone 42 mg. The the product label should include warnings and incidence of treatment discontinuation secondary to adverse events precautions for significant safety concerns was low in the 4 to 6-week placebo-controlled studies: 1. Specifically, in dogs, accumulation of pigmented material in treatment with lumateperone. Following administration of lumateperone for up to 2 years remaining safety uncertainties. Colocalization of pigmented studies, the new safety information should be material in the tissues with inflammation and degenerative changes incorporated in labeling. Although the specific identities of the constituents of the pigmented material were not established, the material is thought to be composed of polymers or protein adducts formed from aniline metabolites of lumateperone that accumulate in the lysosome. At the to-be-marketed dose of 42 mg, plasma levels of the aniline metabolites implicated in the nonclinical toxicities were below the lower limit of quantification in humans. Finally, there was no evidence for the development of relevant adverse events in humans exposed to lumateperone for up to one year of treatment. Accurate diagnosis requires ruling out other potential causes of psychosis, such as other chronic psychiatric illnesses. Specific clinical features of schizophrenia are categorized as positive symptoms. The pathogenesis of schizophrenia is not well-understood, possibly due to the heterogeneity of the syndrome, but it likely involves an interaction between genetic. The onset of schizophrenia is typically in early adulthood, and the course of illness is heterogeneous, with many patients experiencing acute symptom exacerbations and remissions within a chronic and disabling illness. On average, the age of onset occurs 5 to 7 years later in females than males, and when the course of schizophrenia is compared between men and women, women tend to have better premorbid functioning and less prominent negative symptoms and cognitive impairment (Tandon, Nasrallah et al. Schizophrenia is associated with significant impairments in social and occupational functioning and is the 11th leading cause of years lost due to disability worldwide (World Health Organization 2016). Patients with schizophrenia have a significantly higher mortality rate than the general population, with proportionally higher rates of suicide (particularly in younger patients) and cardiovascular disease, as well as other causes (Auquier, Lancon et al. The years of potential life lost in individuals with schizophrenia has been estimated to be 14. Overall, schizophrenia is a serious condition, associated with significant disability and a shortened life expectancy. Analysis of Current Treatment Options Antipsychotics constitute the first-line medication treatment for schizophrenia. Psychiatric practice guidelines recommend that antipsychotics should be initiated as soon as possible in patients with an acute schizophrenia exacerbation and continued through the stable/maintenance phase of the illness to reduce the risk of relapse (Herz, Liberman et al. Antipsychotics are broadly classified as first generation/typical antipsychotics and second-generation/atypical antipsychotics. Typical antipsychotics include those approved before clozapine (before 1989); representative medications of this class are chlorpromazine, fluphenazine, and haloperidol. Atypical antipsychotics include clozapine and others approved after 1989; drugs representative of this class include risperidone, olanzapine, quetiapine, and aripiprazole.

Shelley Reinhardt mental health 4 muslim order lyrica 75 mg amex, the editor-in-chief, went out of her way to nurture a new author. Susan Meigs offered unparalleled editing expertise and countless useful suggestions that were right on target. The entire copyediting and production team turned words and thoughts into a reader friendly and fun package. I especially thank the extraordinary writers who contributed chapters on their specialties for this book. Even while under the stress and hardship of being a res ident, their passion for their chosen careers shines through in their work. This special group of physicians includes Jafer Ali, Vicki Anderson, Kathleen Ang-Lee, Gregory Borschel, Kelly Elmore, Amy Farmer, Derek Fimmen, Jeremy Graff, Danagra Ikossi, Jennifer Lamb, John Langland, Jonathan Le, Daniel Lee, Jane Lewis, Michael Mendoza, Aaron Miller, Andrew Schwartz, Ian Tong, Lisa Var gish, Stephanie Weiss, Lisa Yerian, and Tomasz Zabiega. As they undertake the rst major professional decision of their career, medical students often struggle to come up with a good answer. After all, it seems like just about everyone has a strong opin ion on the best specialty for a future doctor. That person could be an advisor, parent, supervising physician, or even Aunt Betty at the annual family reunion. You have to spend over $200,000 for four years of rigorous education, followed by many long, tough years of on-the-job training. Like life in general, many im portant decisions line the road to becoming a doctor. After slog ging through tedious premedical courses and the application process, you then made the choice of where to attend medical school. The medical school experi ence is more than just memorizing the arteries of the arm, holding retractors dur ing surgery, and learning how to use a stethoscope. Each and every medical stu dent has to go through four years of grueling examinations, sleepless nights on call, and tough clinical rotations. Figuring out what type of doctor to be is, in many ways, more dif cult than deciding to become a physician. Once medical students settle on a speci c niche within medicine, they become more than just future doctors. Graduating doctors have the freedom to choose from a wide variety of medical elds. Some are based strictly on an organ system, like the brain (neurosurgery and neurology), the heart (car diology), and the male genitourinary system (urology). Others provide compre hensive medical care for speci c population groups, such as women (obstetrics and gynecology) and children (pediatrics). Another set of specialties share in com mon the fact that they are hospital-based services. Medical specialties can also generally be divided into two main groups: primary care (long-term comprehen sive care) versus secondary/tertiary care (referral-based care). Generalist special ties like family practice, internal medicine, and pediatrics are considered primary care elds. More specialized areas such as gastroenterology, dermatology, and car diothoracic surgery fall into the latter category. As a result, most students have even less time for the proper self-assessment, research, and explo ration required to choose the right specialty. Every medical student agrees that it is the most difficult professional decision that they will have to make. In the end, many hastily choose their lifetime careers without having all the information they need to make an educated decision. This book is designed to help medical students make an informed choice by the time senior year rolls around. Deciding on a eld of medicine is often de scribed as matching oneself with the characteristics of a particular specialty, such as lifestyle, intellectual challenge, technological focus, and research potential. There are three different types of on-the-job training that com mence immediately following graduation from medical school. These avenues take young, inexperienced doctors and turn them into well-trained specialists, ready to cure disease and save lives. Choosing a specialty determines what form of further professional training is required after medical school. Medical students have to commit to their specialty to begin the next phase in training: residency. During the past 60 years, rapid advancements in medical science created a greater demand for specialists, which residency programs ex panded to meet. Depending on the specialty, residency consists of 3 to 7 years of additional formal training and study (under physician supervision). Residency takes it one step fur ther and confers the skills, knowledge, and experience necessary to practice med icine unsupervised in a given specialty. You work long hours for little pay and spend many nights sleeping in the hospital. In fact, residency earned its name from the old days when house staff physicians actually lived on hospital grounds, as resi dents. Through the National Resident Matching Program, graduating medical stu dents may enter residency training in 20 different specialties. But every year, statistical data from the residency match show that nearly all medical students enter 1 of only 20 areas. After deciding on a specialty for residency, many physicians later choose to subspecialize further by obtaining a fellowship, which can last any number of years. Examples include rheuma tology or infectious disease (internal medicine), vascular surgery (general sur gery), pain management (anesthesiology), and retinal surgery (ophthalmology). Because of all the subspecialties, there are over 60 different kinds of doctors out there! You can be an adolescent medicine specialist, critical care physician, or interventional radiologist. Because areas of subspe cialization are primarily of interest to current residents-in-training, they will not be a major focus of this book. It is important to remember, however, that these elds are all potential career paths. Do not exclude them from your mind while you are contemplating and exploring the 20 basic specialties. In the old days (prior to 1970), all graduating medical students completed a 1-year rotating internship before en tering residency. This busy year consisted of all the core specialties: internal med icine, surgery, pediatrics, obstetrics and gynecology, and psychiatry. The goal was to provide broad hands-on training that would enable a new physician to work in the community as a general practitioner. After the demise of the formal intern ship in 1970, only the lingo lives on today. The old internship does still exist in a disguised form: the transi tional year residency. Medical Students Are Faced With More Choices Than Ever Back in the old days of medicine, the career options for a graduating medical stu dent were pretty simple: become a general practitioner, or. The discovery of inhalation anesthetics gave birth to anesthesiology, progress in drug therapy revolutionized psychiatry, and the development of the colonoscope created gastroenterology.

When the lens is moved in front of the eye, the objects move in the opposite direction. When the lens is moved in front of the eye, the objects move in the same direction ii. The axis of a cylindrical lens is parallel to that of the cylinder of which it is a part. When the lens is moved in the direction of the axis, there is no movement of the objects. Contact Lenses Principle Contact lens alters the vergence power of the anterior surface of the eye. Cosmetic It improves the cosmetic appearance specially in young marriageable girls. Each surgeon may have a preference for a particular procedure depending on economic reasons, availability factor or his own personal satisfaction with the end results. The aim of astigmatic keratotomy is to flatten the more curved meridian by asymmetrical incisional surgery. To achieve this various considerations are kept in mind such as the number and position of the transverse incisions. The central part of the cornea (optical zone) is reshaped by the laser after corneal epithelial debridement. Excimer laser photorefractive keratectomy directly alters the central cornea Method Excimer lasers (excited dimer) act by tissue modelling (Photoablation). It is a source of far ultraviolet radiation which allows removal of corneal tissue with the accuracy of a fraction of a micron. Laser energy has been used to perform radial keratotomy as the laser incision is more accurate and predictable than a diamond knife incision. Disadvantages There may be residual corneal haze in the centre affecting clear vision. In this procedure a 160 micron hinged corneal flap is lifted from the central 8 to 9 mm of cornea with the help of a microkeratome. This flap is folded to the side and the excimer laser is then used to remove tissue from the exposed surface, correcting myopia and astigmatism. It reinforces the posterior capsule to hold the vitreous phase thus minimising incidence of retinal detachment. Method the donor lenticule of the desired power is sutured into the keratectomy with 10-0 nylon sutures. This disc is placed on a lathe machine equipped with freezing apparatus and keratomileusis (grinding) is performed. Recently Coherent Schwind laser and fourth generation fractile mask spiral lasers are under trial which will further decrease the corneal ablation time.

Etiology (See also physiology and pathophysiology of aqueous humor circu lation): the cause of primary open angle glaucoma is not known mental disorders schizophrenia symptoms purchase 75 mg lyrica visa, although it is known that drainage of the aqueous humor is impeded. The primary lesion occurs in the neuroretinal tissue of the optic nerve as compression neuropathy of the optic nerve. Symptoms: the majority of patients with primary open angle glaucoma do not experience any subjective symptoms for years. However, a small number of patients experience occasional unspecific symptoms such as headache, a burning sensation in the eyes, or blurred or decreased vision that the patient may attribute to lack of eyeglasses or insufficient correction. The patient may also perceive rings of color around light sources at night, which has tradition ally been regarded as a symptom of angle closure glaucoma. Primary open angle glaucoma can be far advanced before the patient notices an extensive visual field defect in one or both eyes. It is crucial to diagnose the disorder as early as possible because the prog nosis for glaucoma detected in its early stages is far better than for advanced glaucoma. Where increased intraocular pressure remains undiagnosed or untreated for years, glaucomatous optic nerve damage and the associated visual field defect will increase to the point of blindness. Elevated intraocular pressure in a routine ophthalmic examination is an alarming sign. The angle of the anterior chamber is open and appears as normal as the angle in patients without glaucoma. Examination of the optic nerve reveals whether glaucoma tous cupping has already occurred and how far advanced the glaucoma is. Where the optic disk and visual field are normal, ophthalmoscopic examina tion of the posterior pole under green light may reveal fascicular nerve fiber defects as early abnormal findings. Noise field perimetry is suitable as a screening test as it makes the patient aware of scotomas and makes it possible to detect and describe them. The patient is shown a flickering monitor displaying what resembles image noise on a television set. In advanced glaucoma, kinetic hand pe rimetry with the Goldmann perimeter device is a useful preliminary exami nation to evaluate the remaining field of vision. Differential diagnosis: Two disorders are important in this context: Ocular hypertension. Patients with ocular hypertension have significantly increased intraocular pressure over a period of years without signs of glauco matous optic nerve damage or visual field defects. Some patients in this group will continue to have elevated intraocular pressure but will not develop glaucomatous lesions; the others will develop primary open angle glaucoma. The probability that a patient will develop definitive glaucoma increases the higher the intraocular pressure, the younger the patient, and the more com pelling the evidence of a history of glaucoma in the family. Patients with low-tension glaucoma exhibit typical progressive glaucomatous changes in the optic disk and visual field without elevated intraocular pressure. These patients are very difficult to treat because management cannot focus on the control of intraocular pressure. Often these patients will have a history of hemodynamic crises such as gastrointestinal or uterine bleeding with significant loss of blood, low blood pressure, and peripheral vascular spasms (cold hands and feet). Patients with glaucoma may also experience further worsening of the visual field due to a drop in blood pressure. Caution should be exercised when using cardiovascular and anti-hyper tension medications in patients with glaucoma. O Glaucomatous changes in the optic cup: Medical treatment should be initiated where there are signs of glaucomatous changes in the optic cup or where there is a difference of more than 20% between the optic cups of the two eyes. O Increasing glaucomatous changes in the optic cup or increasing visual field defects: Regardless of the pressure measured, these changes show that the current pressure level is too high for the optic nerve and that additional medical therapy is indicated. O Early stages: It is often difficult to determine whether therapy is indicated in the early stages, especially where intraocular pressure is elevated slightly above threshold values. Patients with suspected glaucoma and risk factors such as a family history of the disorder, middle myopia, glaucoma in the other eye, or differences between the optic cup in the two eyes should be monitored closely. Follow-up examinations should be performed three to four times a year, especially for patients not undergoing treatment. Principles of medical treatment of primary open angle glaucoma: Medical therapy is the treatment of choice for primary open angle glau coma. However, several principles may be formulated: O Where miosis is undesirable, therapy should begin with beta blockers (Table 10. O Where miosis is not a problem (as is the case with aphakia), therapy begins with miotic agents. O Miotic agents may be supplemented with beta blockers, epinephrine derivatives, guanethidine, dorzolamide and/or latanoprost maximum topical therapy). O Osmotic agents or carbonic anhydrase inhibitors (administered orally or intravenously) inhibit the production of aqueous humor.

O the effectiveness of any pressure-reducing therapy should be verified by pressure analysis on the ward or on an outpatient basis. Tolerance, effects, and side effects of the eyedrops should be repeatedly verified on an individual basis during the course of treatment. Reactions include allergy, reduced vision due to narrowing of the pupil, pain, and ciliary spasms, and ptosis. O the patient is not a suitable candidate for medical therapy due to lack of compliance or dexterity in applying eyedrops. O In acute angle closure glau coma, the forced narrow ing of the pupil and the extrac tion of the iris from the angle of the anterior chamber are most impor tant.

The plasma radioactivity half-life is much longer in dogs (116 hours) than in humans (12 hours) and rats (20 hours) mental treatment 104 generic lyrica 75mg mastercard, and the reason is unknown. As shown in Table 103, glucuronidated metabolites represent about 51% of the total radioactivity in the human plasma, but only 9% of total radioactivity in dogs. Table 103: Mass Balance Study in Humans, Dogs and Rats Using 14C-Labeled Lumateperone Humans(n=6) Dogs (n=3) Rats (n=3) Dose 28 mg 3. Lumateperone and its 5 metabolites (M161, M308, M131, M565, M309) can be further glucuronidated. Source: modified based on meeting minutes for March 28, 2017 meeting Up to 5 unconjugated metabolites were monitored in the animal and human studies, and these were found to accumulate at different concentrations relative to the parent drug in each species. Specifically, the most abundant circulating moiety in humans is a tertiary down-stream metabolite, M309, which circulates at a level about 5. In dogs, metabolite M161, a primary demethylation product, circulates at a level about 3. These data show that major metabolic pathways are qualitatively similar in humans, dogs, and rats, but quantitative differences exist, as relative levels of metabolites vary considerably across species. The Applicant claims that these two aniline metabolites cause the observed neurotoxicity in dogs and assert that they are not formed in humans. Figure 37: Formation of Aniline Metabolites Note: No studies were performed to elucidate explicitly the formation process of M337 and M338. It is postulated that the two aniline metabolites, M337 and M338, can be formed by 2-carbon scission from M131 (ketone reduction product of lumateperone) and demethylation metabolite of lumateperone, respectively. Therefore, M337 and M338 could not be directly measured through radioactivity detection in the mass balance studies. Source: meeting minutes for March 28, 2017 meeting Following daily oral administration of lumateperone at 1. Human data reported from the one year open-label safety extension study (Study 303) show no quantifiable levels in patients treated with lumateperone 42 mg/day, with approximately 500, 300, and 100 subjects exposed through 1, 6, and 12 months, respectively. Figure 38: Plasma Concentration Time Profile of M337 and M338 on Day 280 Following Daily Oral Administration of Lumateperone (1. Because the 14C label was placed on a carbon that was cleaved off during this process, aniline metabolites could not be directly measured through radioactivity detection in the mass balance studies. Instead, the two-carbon fragments carried the 14C-carbon, and they could be monitored through radioactivity detection. Assuming a 1:1 ratio between production of two carbon fragments and aniline metabolites, the detection of two-carbon fragments in mass balance studies can be used as an indicator of aniline metabolite formation. The two-carbon fragments have low molecular weight and are highly polar; as a result, they are eluted as an early peak, between 1. In addition, a similar early elution peak with comparable retention time was also observed in the radiochromatograms from human urine and feces samples respectively (data not shown). Therefore, on the basis of these data, one cannot rule out the possibility that aniline metabolites are formed in humans as well. No conclusions can be drawn regarding associations between single metabolites and neurotoxicity on the basis of the available database. The observed multi-organ pigment accumulation and neuronal degeneration in animal studies, might be a collective effect of the lumateperone and/or its metabolites. Unfavorably, because the time gap from lumateperone administration in the evening to blood sample collection the next day, there is a possibility that the early signals immediately following the lumateperone administration might be missed. However, peaks detected at the targeted retention times for the metabolites in the chromatograms were noticeable in some patients, suggesting that the aniline metabolites might be formed in some patients though in limited quantities. The third round of efforts was made to measure the aniline metabolites in freshly-collected plasma samples from patients dosed to steady state in an ongoing clinical trial. Results from a total of number of 11 patients dosed at 42 mg lumateperone were submitted on Nov. Unfortunately, the steady state of these patients has been disrupted by skipping of the evening dose, which is the way they have been taking lumateperone per study protocol instruction. Summary information of data and demographics included in the analysis is shown in Table 104. This review focused on the 9-month beagle dog study and the 2-year Sprague Dawley rat study with Lumateperone on which we have previously reported (reference 4). Specifically, for this response, we have evaluated targeted brain and spinal cord slides of these two studies which were obtained from the sponsor to answer your specific questions (reference 1). We also integrated in our answers to your questions, information we recently received and evaluated which was presented in the six attachments of reference 2. Specifically, we have evaluated and commented on the draft reports of references 2c and 2d previously (reference 3). In particular we would like you to evaluate slides processed and provided by the Applicant and address the following questions regarding the lysosomal accumulation of pigmented material in the central nervous system of dogs and rats treated with lumateperone for up to 9 months (dogs) or 2 years (rats). We previously summarized the characteristics of lysosomal drug pigment accumulations, reported by the respective study pathologists (reference 4, pg. Our independent slide evaluations, overall, confirmed these descriptions of the pigment. The pigment was described to be yellowish-brown, orange or red, material, located mainly in neurons, phagocytic cells (macrophages), and choroid plexus epithelial cells, as well as occasionally free in the extracellular space (indicative of release from degenerate/necrotic cells). Pathology comment: the results of the 3-month dog study described and depicted in photomicrographs co-localization of drug pigment in the same or nearby neurons (reference 1aii pg. We consider the 3-month dog study changes (neuronal degeneration and necrosis) to be precursor lesions to the perivascular cuffing and axonal degeneration reported in the 9-month study. For a better illustration of this connection, we have provided selected photomicrographs below from the study report of the 3-moth dog study and photomicrographs we took during our slide review of the 9-month dog study. Note the red drug pigment in neurons (white arrow) and adjacent perivascular cuffing or inflammation (black arrow). Note the perivascular cuff (lymphocytes/macrophages) has a few pigmented macrophages (white arrow). The described lysosomal pigment accumulation represents an impaired lysosomal storage state exhibiting characteristics similar to lysosomal storage diseases resulting from endogenous or exogenous causes reported in the published literature. An impaired lysosomal storage state is defined as the accumulation of material resistant to or exceeding the capacity of the machinery responsible for intracellular digestion, disposal and transport. The implication is that the catabolic machinery of the cell is fundamentally incompetent leading to steady progressive product accumulation, undegradable by the affected cell. Limited capacity of neurons to discharge the stored material via exocytosis has been reported but in general intractable constipation is inevitable as long as the cause of the entrapment is not resolved. Therefore, if neurons are involved, clinical signs of neurological impairment become eventually evident, but may not correlate with significant histological evidence of neuronal death. Reginal neuronal death occurs early and is progressive resulting in functional disturbance as there is no recourse for neurons except to accumulate pigment until the cell or the animal dies (Maxie and Youssef, 2007, pg. With prolonged treatment time and/or higher doses, this was then followed by an initial reactive (b) (4) inflammatory (histiocytic) response (as coined for sciatic nerve by, reference 2d, pg. Alternatively, do these lesions appear to be unrelated to lysosomal accumulation of pigmented material and, therefore, related to a direct neurotoxicity by other means. As outlined above, we believe that the reported lesions (perivascular cuffing and axonal degeneration) described in the brain and spinal cord of dogs are related to the lysosomal accumulation of pigmented material (drug pigment). Question 2: Does the lysosomal accumulation of pigmented material in neurons in the spinal cord of rats contribute to the lesions observed in this tissue Is the location of lysosomal accumulation of pigmented material in neurons in the spinal cord of rats consistent with the location of axonal degeneration in this tissue Therefore, consistent with lysosomal storage diseases, the targeted review and our slide review points to neurons potentially being affected anywhere in the spinal cord gray matter, without location predilection. Therefore, the reported axonal degeneration could occur anywhere in the white matter tracks. It should also be noted that both findings, neuronal pigmentation and axonal degeneration are dose responsive in both sexes where neuronal pigmentation consistently preceded axonal degeneration in incidence. Is the lysosomal accumulation of pigmented material in the spinal cord of rats associated with an inflammatory response in this tissue However, in his draft report, referred to this observation as foci of granule-packed glial cells as well as gliosis focal and gliosis multifocal.

Thus, in the rare instances We believe that this model can be a useful tool in assessing immune therapy when clinical studies are conducted to confrm botanical-drug interaction safety both in preclinical but also clinical development of therapeutics. In studying and in Combination with Pharmaceutical the complex mixture in this way, we can capture the overall net efect of any Agents synergism or additive efects that might be occurring. Retail sales of vitamins and nutritional supplements have increased from S 2550 Cannabidiol Pharmacology and Drug-Drug $23. While many equate these natural products with safe, it is well recognized by scientists that active T. Mendrick products are used in concert with pharmaceutical agents, they can alter drug metabolism and drug delivery, thereby enhancing or reducing the therapeu There has been increasing interest in the use of cannabinoids in the treatment tic efect of the drug(s). This presentation will in plore the toxicity of natural products alone and in combination with con troduce the pharmacology of cannabidiol, including proposed mechanisms ventional drugs. Systematic approaches for assessing natural product-drug of action, pharmacokinetics, metabolism, and excretion. Methodology to handle the complex mixtures represented documented, clinically signifcant interactions with clobazam and valproate by natural products in various test systems also will be discussed. Other potential pharmacokinetic interactions have been seen with interaction will be highlighted. However, more data are needed to confrm many of these potential drug-drug interactions. Underlying Interactions between Prescription and Nonprescription Medications and Natural Products W 2551 New Approaches Using Mode-of-Action to M. A established, such as skin sensitization, genetic toxicity, and endocrine models. The presentations will provide a synopsis of the state ally, improved decisions about the optimal management of these complex of-the-science regarding availability of databases for these endpoints, as well interactions. Discussion will focus on what is needed to bring 2549 Botanical-Drug Interaction Assessment: A these approaches into broad regulatory use. Exposure to botanicals in dietary supplements is increasing across many ge ographies; with increased expectations from consumers, regulators, and in dustry stewards centered on quality and safety of these products. We have developed in silico mechanistic proflers that identify putative molec Echocardiography provides a noninvasive means to assess cardiac structure ular initiating events. Increasingly, echo and fngerprinting of in vitro data, which is integrated in some cases with cardiography has become a sought-after tool in nonclinical research to make a consensus model using protein docking binding energies. Uniquely, our informed decisions on intended pharmacology and/or of-target actions of models can provide both positive and negative predictivity when there are test articles under development. This session will aim to provide an overview enough specifc negative in vitro data. We are aligning the predicted in silico of the utility of echocardiography in nonclinical research, including the lat targets with appropriate in vitro models in an integrated manner to predict in est novel technologies, species and study design considerations, and a reg vivo toxicity. The session will start with an outline of the use of small (rodents) down-stream in vitro models for basal cytotoxicity. For instance, we demon and large (dogs, monkeys) animal echocardiography, including a description strate using in silico approaches to identify in vitro models that lack compre of common endpoints assessed. In addition, the frst presenter will address hensive predictivity due to poor metabolic capability, inability to delineate the utility of echocardiography in healthy animals and animal models of car cytotoxicity from known cytotoxic reactive chemistries, or by questionable in diac disease as part of nonclinical safety assessment. These studies will highlight potential research gaps tion will address a range of anatomic, behavioral, and hemodynamic factors and future projects. Based on the fact that cardiovascular for assigning regulation classifcations to chemicals. Determining whether a liabilities continue to be a leading cause of drug attrition in late-stage clinical substance has a specifc mode of action, which may drive toxicity in one or trials and post-market approval, it is expected that additional measures to more organs, or is non-specifc in its action is an essential part of determin assess cardiac function will be of great interest to the toxicology and drug ing toxic potency, and hence will infuence regulatory classifcations. Therefore, both systems are ideal for nonclinical imaging and drug screening in a wide range of animal species. Doppler measures of blood velocities moving through valves and other blood vessels Although predicting adverse efects has traditionally concentrated on ob will add additional insight. This presentation will cover the range of measure servations at the organ and organismal level, we know that these adverse ments used in cardiac ultrasound in healthy animals and animal models of events are the culmination of a chain of events that begins with an interaction cardiac disease that may be employed as part of nonclinical safety assessment between the exogenous chemical and an endogenous target at the molec studies. Accordingly, we have concentrated on trying to understand the modes of action of toxicants at a molecular level, both by analyzing chemical features and by identifying the initial biological responses to toxicants. Using these data, we are deriving mode of action ontologies that link molecular targets to in vivo B. We are supporting our assumptions about mode of action by using global gene expression analysis in a series of cell types that provide biological Echocardiography is increasingly used as an assessment of the cardiac ef diversity. This talk will demonstrate progress on the mode of action ontology, fects of test articles. The modality permits non-invasive, repetitive, rapid as and provide examples of how the ontology and data from toxicogenomics sessments of cardiac size, including markers for myocardial mass, indices of provides support for prediction of toxicity by read across. In the process, we hemodynamics, and quantitative indices for systolic and diastolic function. Interpretation schemes will be discussed, including principles such as asymmetric cause/efect analysis. Hypothetical examples of optimum versus non-optimum use of echocardiography in test article devel opment will be presented. These are consistent with the goals of refn commonly for hazard classifcation and labeling and/or risk assessment for ing, reducing, and replacing animal studies while also increasing the safety of acute chemical exposures. To identify opportunities for the implementation of clinical trials for participants. Recent advances in echocardiography give this non-animal approaches to produce these data, the regulatory needs and uses imaging modality the potential to have a signifcant impact on nonclinical for acute systemic toxicity information must frst be clarifed. Echocardiography is a non-invasive or minimally invasive the current regulatory use and acceptance of non-animal data is a necessary technique that ofers in-life visualization of several components of cardiac starting point for future method development, optimization, and validation function and blood fow and quantitative assessment of physiologic or toxico eforts. Its successful implementation in nonclinical studies and submis commitment to integrating non-animal methods. This talk will provide an sion to regulatory agencies is dependent on several key factors, including the overview of federal agency needs for acute systemic toxicity data, and high observer, analysis, and reporting. This presentation will discuss the potential light potential opportunities for implementing new approach methodologies use of echocardiography in nonclinical studies and the types of benefcial to meet such needs. It will also highlight recent initiatives that have resulted information to include when submitting to regulatory agencies.
