Petros begins enrollment in AI integrated Human Factors Study to optimize self-screening, continuing its efforts to make STENDRA (avanafil) the first erectile dysfunction medication to achieve OTC Status (Please see important safety information below) NEW YORK, NY / ACCESSWIRE / March 19, 2024 / Petros Pharmaceuticals, Inc. (NASDAQ:PTPI), a company focused on expanding consumer access to medication through over-the- counter (OTC) drug development programs, announces it has successfully launched its artificial intelligence (AI) tool developed as a result of its collaboration with a multi-billion-dollar software developer. The tool is being integrated into the Company's web app being used for patient self-screening, which it is testing in its recently launched Human Factors study. Fady Boctor, Petros' President and Chief Commercial Officer, commented, "The utilization of AI is a logical progression as we aim to optimize the safe administration of STENDRA (avanafil), in development for OTC availability. In addition, based on our recent interaction with the FDA on our technology approach, we believe the AI component directly addresses requests made by the Agency in order to optimize selection. Ultimately, we believe the AI will help us to gather information to ensure that the patient is appropriate to receive the drug. Importantly, we continue to believe that we have sufficient funding to achieve our development goals as well as significant near-term clinical milestones for STENDRA." The Human Factors Study, which incorporates the AI tool, is designed to assess whether the web tool developed by the company can be used safely and effectively by its intended users. Subjects will be asked to perform critical tasks with the web app without any guidance from the study staff. The study is based on applicable FDA guidance for human factors studies. The outcomes from this study will further contribute to discussions with the U.S. Food and Drug Administration (FDA) regarding the need for the Additional Condition of Nonprescription Use (ACNU) with regard to the web app and the Company's endeavors to develop STENDRA into the first erectile dysfunction medication to go OTC. About Petros Pharmaceuticals Petros Pharmaceuticals is committed to the goal of becoming a leading innovator in the emerging self-care market driving expanded access to key prescription pharmaceuticals as Over-the-Counter treatment options. Currently, Petros is pursuing increased access for its flagship prescription ED therapy, STENDRA, via potential OTC designation. If ultimately approved by the FDA for OTC access, STENDRA may be the first in its class to achieve this marketing status, also establishing company know how as a proven platform for other prospective prescription therapeutics. About the OTC Pathway The process of switching a prescription medication to over the counter (OTC) first involves the design of a Drug Facts Label (DFL) that is well understood by potential consumers. Then data must show that consumers can make an appropriate decision to use or not to use the product based only upon the information on the DFL and their personal medical history. Then consumers must demonstrate that they can properly use the product based upon the information on the DFL. To accomplish these things, the FDA ordinarily requires a consumer tested OTC DFL. This testing includes conduct of iterative Label Comprehension Studies (LCS) in the general population, Self-Selection Studies (SSS) in a population interested in using the product and in specific populations who may be harmed if they use the product, and usually one Actual Use Trial (AUT) demonstrating safe and appropriate use by consumers in a simulated OTC setting. The regulations that FDA is currently finalizing introduced Additional Conditions for Nonprescription Use (ACNU) criteria that enable correct self-selection by consumers and may expand OTC access to medications that formerly could only be available by prescription. An ACNU may be an innovative computerized tool, or the additional conditions may use other approaches that support the switch process. Important Safety Information about STENDRA® (avanafil) STENDRA® (avanafil), originally launched by Auxilium Pharmaceuticals prior to that company's sale to Endo Pharmaceuticals, is an oral phosphodiesterase 5 (PDE5) inhibitor for the treatment of erectile dysfunction. STENDRA is not for use in women or children. It is not known if STENDRA is safe and effective in women or children under 18 years of age. (A 100-mg and 200-mg tablet can be taken as early as ~15 minutes before sexual activity. STENDRA only works with sexual stimulation and should not be taken more than once a day. STENDRA can be taken with or without food; do not drink too much alcohol when taking STENDRA (for example, more than 3 glasses of wine or 3 shots of whiskey) as it can increase chances of side effects. Of people enrolled in clinical trials, 1.4%, 2.0%, and 2.0%, respectively, stopped taking STENDRA (50 mg, 100 mg, or 200 mg) due to side effects compared to 1.7% on placebo. STENDRA® was designed and developed expressly for erectile dysfunction. STENDRA is contraindicated with any form of organic nitrates, in patients with known hypersensitivity to any component of the tablet, and in patients who are using a guanylate cyclase stimulator. Patients should not use STENDRA if sexual activity is inadvisable due to cardiovascular status or any other reason. Before taking STENDRA tell your doctor if you have had any kind of heart issues including heart attack, heart failure, angina and irregular heartbeat or have elevated or low blood pressure. Use of STENDRA with alpha-blockers, other antihypertensives, or substantial amounts of alcohol (greater than 3 units) may lead to hypotension. Patients should seek emergency treatment if an erection lasts greater than 4 hours. Patients should stop STENDRA and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of Non Arteritic Ischemic Optic Neuropathy (NAION). Discuss with patients the increased risk of NAION in patients with a history of NAION. Patients should stop taking STENDRA and seek prompt medical attention in the event of sudden decrease or loss of hearing. STENDRA can potentiate the hypotensive effect of nitrates, alpha blockers, antihypertensives, and alcohol. CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, erythromycin) increase STENDRA exposure. For patients taking concomitant strong CYP3A4 inhibitors (including ketoconazole, ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir and telithromycin), do not use STENDRA. Combination with Other PDE5 Inhibitors or Erectile Dysfunction Therapies is not recommended. The safety of STENDRA is unknown in patients with bleeding disorders and patients with active peptic ulceration. The use of STENDRA offers no protection against sexually transmitted diseases including HIV. Consider counseling patients on protective measures for sexually transmitted diseases. The most common adverse reactions reported with use of STENDRA include headache, flushing, nasal congestion, nasopharyngitis, and back pain. For more information about STENDRA, call 844-458-4887.

KarXT is also undergoing registrational trials as an adjunctive therapy for schizophrenia and for treating psychosis in Alzheimer’s disease patients. Its potential for further indications such as bipolar 1 disorder and agitation in Alzheimer’s disease is being explored. Financial advisory services for the deal were provided to BMS by Gordon Dyal and Citi, with Covington & Burling offering legal counsel. Goldman Sachs acted as exclusive financial adviser to Karuna, with Simpson Thacher & Bartlett providing legal counsel. Bristol Myers Squibb CEO Chris Boerner stated: “We are excited to expand our neuroscience portfolio as we welcome Karuna to Bristol Myers Squibb. “Importantly, this transaction aligns with our commitment to strengthening BMS’s growth profile in the latter half of the decade and beyond. We look forward to working with Karuna’s talented team to bring KarXT to patients with schizophrenia later this year.” The new development comes after the FDA’s committee voted eight to three to approve BMS and 2seventy bio’s Abecma to treat relapsed or refractory multiple myeloma .

SOD1- ALS is a devastating, uniformly fatal, and ultra-rare genetic form of ALS that represents approximately two percent of all ALS cases1 Health Canada regulatory decision on tofersen New Drug Submission expected in early 2025 TORONTO, March 19, 2024 /CNW/ - Biogen Canada Inc. announced today that Health Canada has accepted for review a New Drug Submission(NDS) for tofersen for the treatment of amyotrophic lateral sclerosis (ALS) in adults who have a mutation in the superoxide dismutase 1 (SOD1) gene. If approved, tofersen will be the first treatment indicated in Canada to target a genetic cause of ALS. "The tofersen New Drug Submission represents a critical milestone for the Canadian ALS community and those suffering from this ultra-rare genetic form of the disease that robs them of time with loved ones," said Eric Tse, General Manager of Biogen Canada. "For over a decade, Biogen has been committed to advancing ALS research to provide a deeper understanding of this devastating disease. We are passionate about doing what we can to make a difference and are deeply committed to the rare disease community." According to the ALS Society of Canada, ALS currently impacts an estimated 4,000 Canadians, with approximately 1,000 new Canadians diagnosed each year.2 The NDS is based on results from the Phase 3 VALOR trial, a 28-week randomized, double-blind, placebo-controlled clinical study, which assessed the safety and efficacy of tofersen in patients with weakness attributable to ALS and a confirmed SOD1 mutation. A regulatory decision on the New Drug Submission is expected in early 2025. About tofersen Tofersen is an antisense oligonucleotide (ASO) designed to bind to SOD1 mRNA to reduce SOD1 protein production. The U.S. Food and Drug Administration granted accelerated approval for QALSODY™ (tofersen) to treat amyotrophic lateral sclerosis (ALS) in adults who have a mutation in the superoxide dismutase 1 (SOD1) gene based on reduction in plasma neurofilament light chain (NfL) observed in patients treated with tofersen. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trial(s).3 Tofersen also received a positive opinion from the European Medicines Agency's Committee for Medicinal Products for Human Use (CHMP) recommending its marketing authorization under exceptional circumstances for the treatment of adults with ALS associated with a mutation in the SOD1 gene.4 A decision on a marketing authorization in the European Union is expected in the second quarter of 2024. Biogen licensed tofersen from Ionis Pharmaceuticals, Inc. under a collaborative development and license agreement. Tofersen was discovered by Ionis. In addition to an ongoing open label extension (OLE) of VALOR, tofersen is being studied in the Phase 3, randomized, placebo-controlled ATLAS study to evaluate whether tofersen can delay clinical onset when initiated in presymptomatic individuals with a SOD1 genetic mutation and biomarker evidence of disease activity (elevated plasma NfL). More details about ATLAS (NCT04856982) can be found at clinicaltrials.gov. About Amyotrophic Lateral Sclerosis and SOD1-ALS Amyotrophic lateral sclerosis (ALS) is a rare, progressive, and fatal neurodegenerative disease that results in the loss of motor neurons in the brain and the spinal cord that are responsible for controlling voluntary muscle movement. People with ALS experience muscle weakness and atrophy, causing them to lose independence as they steadily lose the ability to move, speak, eat, and eventually breathe. Average life expectancy for people with ALS is three to five years from time of symptom onset.5 Multiple genes have been implicated in ALS. Genetic testing helps determine if a person's ALS is associated with a genetic mutation, even in individuals without a known family history of the disease. More than 15 percent of people with ALS are thought to have a genetic form of the disease;6 however, they may not have a known family history of the disease.1 SOD1-ALS is diagnosed in approximately two percent of all ALS cases.1 In people with SOD1-ALS, mutations in their SOD1 gene cause their bodies to create a toxic misfolded form of SOD1 protein. This toxic protein causes motor neurons to degenerate, resulting in progressive muscle weakness, loss of function, and eventually, death.6 Biogen's Continuous Commitment to ALS For over a decade, Biogen has been committed to advancing ALS research to provide a deeper understanding of all forms of the disease. The company has continued to invest in and pioneer research despite making the difficult decision to discontinue a late-stage ALS asset in 2013. Biogen has applied important learnings to its portfolio of assets for genetic and other forms of ALS, with the goal of increasing the probability of bringing a potential therapy to patients in need. These applied learnings include evaluating genetically validated targets in defined patient populations, pursuing the most appropriate modality for each target and employing sensitive clinical endpoints. In addition to tofersen, the company has a pipeline of investigational drugs being evaluated in ALS, including BIIB105.
