Expands Adrenergic Pipeline to Address Neurogenic Orthostatic Hypotension and Major Depressive Disorder in Older Adults SAN CARLOS, Calif.--(BUSINESS WIRE)--CuraSen Therapeutics, Inc., a clinical-stage biopharmaceutical company developing oral, rapid onset, small molecule drugs to treat psychiatric and neurodegenerative diseases, announced today that it has appointed Kathleen Sereda Glaub, MBA, formerly executive chair, as chief executive officer. Dr. Anthony Ford will move to the role of president and chief scientific officer, and continue to lead research and development. Patrick Enright, managing director of Longitude Capital, will become chair of the board. Along with these executive changes, the company announced clinical program updates for its drug candidates that are each designed to restore adrenergic stimulus that declines with age or disease. CuraSen’s most recent development candidate is CuraAX (CST-3056), an alpha-1A adrenoceptor (α 1A -AR) agonist being developed as a treatment for neurogenic orthostatic hypotension (nOH). The company is planning to submit an investigational new drug (IND) application this quarter. A significant orphan indication affecting approximately 120,000-150,000 patients in the U.S., nOH is a dysfunction in the autonomic nervous system common in Parkinson’s disease (PD) and related diseases that causes sudden drops in blood pressure upon standing. This can lead to debilitating dizziness, weakness, cognitive decline and dangerous falls. CuraAX is a selective, CNS-penetrant, α 1A -AR agonist designed to provide cognitive benefit as well as control harmful blood pressure deviations. CuraCN (formerly known as CST-103/CST-107), a beta2 adrenoceptor (β 2 -AR) agonist combination, is targeted for a Phase 2b study in major depressive disorder in adults 65 and older, many of whom also suffer from cognitive decline. These plans are based on the company’s previous Phase 2 clinical study in patients that revealed compelling evidence of anti-depressant efficacy and improvements in cognition tests. CuraXN (formerly known as CST-2032/CST-107), a second β 2 -AR agonist combination, is in development for Alzheimer’s disease (AD) to address both cognitive symptoms and disease progression. All three drug candidates work by restoring adrenergic function that declines with age and, in particular, is lost early in neurodegenerative diseases such as AD & PD. CuraSen’s development candidates have strong potential to improve cognitive function and mood, in addition to addressing specific aspects of disease pathobiology. “We are thrilled to have Ms. Glaub assume the role of chief executive officer as CuraSen seeks to capitalize on the company’s adrenergic platform and clinical data to develop a broad pipeline of drugs for psychiatric and neurodegenerative diseases. These include opportunities for a significant, fast-to-market, orphan opportunity in neurogenic orthostatic hypotension,” said Mr. Enright, board chair. “CuraSen will benefit from the collective and complementary executive experience of both Ms. Glaub and Dr. Ford, both co-founders of the company.” Ms. Glaub brings more than 30 years of experience in biopharmaceutical corporate development, strategy, financing and company-building. She serves on the board of directors of IO Biotech, and previously served on the boards of Codexis, Aligos Pharmaceuticals and Escient Pharmaceuticals. Ms. Glaub was previously chief executive officer of Afferent Pharmaceuticals, which was acquired by Merck in 2016 for $1.25 billion. Under her leadership, the company advanced gefapixant to Phase 3 readiness for the treatment of chronic cough and raised $80 million in additional private funding for Afferent. Previously, she served as president of Plexxikon, and helped develop two FDA-approved drugs, Zelboraf® for metastatic melanoma and Turalio® for tenosynovial giant cell tumor (TGCT). She led Plexxikon’s business and financing strategy, negotiated multimillion-dollar partnerships, and led the sale of the company to Daiichi Sankyo for nearly $1 billion. She previously held positions as senior vice president and chief financial officer of Cell Genesys, treasurer of Genentech, and various finance and treasury roles with Intel Corporation. Ms. Glaub received her BA from the University of California, Berkeley, and her MBA from Northwestern University. “CuraSen’s expertise in adrenergic pharmacology, chemistry and clinical development has led to the discovery of three promising drug candidates focused on some of the most debilitating and common neurodegenerative and psychiatric diseases affecting patients and their families. Our adrenergic target mechanisms are already validated by approved drugs in a range of indications, and we have confirmed the ability to develop CNS-penetrant compounds with a unique approach to safety,” said Glaub. “Given the strong and rapid-onset efficacy signals pointing to an anti-depressant effect in our past studies and our understanding of adrenergic deficits in older adults, we believe there is a unique opportunity to address depression in these patients with CuraCN. With CuraXN, we hope to deliver a transformational treatment for Alzheimer’s disease with our holistic approach to restoring brain functionality and health. Lastly, with CuraAX, we believe we can offer major advantages over current treatments for nOH, including durability of efficacy and cognitive benefit, dosing convenience and improved safety.” About CuraSen Therapeutics CuraSen is focused on the development of new treatments for psychiatric and neurodegenerative diseases, including neurogenic orthostatic hypotension, major depressive disorder and Alzheimer’s disease. CuraSen’s drugs are small molecule, oral tablets designed to activate certain receptor populations in the brain to compensate for decline of the adrenergic system driven by aging and disease. The company has evaluated two β 2 -AR agonist candidates, CuraCN and CuraXN, in multiple Phase 2 clinical studies for effects on memory, attention, executive function and mood, as well as safety and tolerability. CuraSen is planning to submit an IND application by the end of 2024 for its third drug candidate CuraAX, an α 1A -AR agonist, for the treatment of nOH. For more information, please visit .

NEW YORK--( BUSINESS WIRE )-- Pfizer Inc. (NYSE: PFE) today announced longer-term follow-up results from the Phase 2 single-arm PHAROS clinical trial evaluating the efficacy and safety of BRAFTOVI ® (encorafenib) in combination with MEKTOVI ® (binimetinib) for patients with BRAF V600E - mutant metastatic non-small cell lung cancer (NSCLC). After an additional 18 months of follow-up, the objective response rate (ORR) and the median duration of response (DoR) as assessed by independent radiology review were 75% and 40 months in treatment-naïve patients and 46% and 16.7 months in previously treated patients, respectively. In addition, after approximately three years of follow-up in treatment-naïve patients, the median progression-free survival (PFS) with BRAFTOVI + MEKTOVI was 30.2 months (95% confidence interval [CI], 15.7-not estimable [NE]), while median overall survival (OS) was not yet reached (95% CI, 31.3-NE). These data will be presented today during a late-breaking oral session (Abstract LBA56) at the European Society for Medical Oncology (ESMO) Congress 2024 in Barcelona, Spain. “ BRAF V600E-mutant metastatic non-small cell lung cancer tends to be aggressive, and effective targeted first-line treatment options with manageable safety profiles are critical for the thousands of people who are diagnosed globally each year,” said Gregory Riely, M.D., Ph.D., Vice Chair, Clinical Research in the Department of Medicine at Memorial Sloan Kettering Cancer Center (MSK) and PHAROS investigator. “ The longer-term follow-up results from the PHAROS trial represent an important step forward in the treatment of BRAF V600E-mutant metastatic NSCLC, especially for treatment-naïve patients. These compelling results support the BRAFTOVI + MEKTOVI combination as a standard of care option for these patients.” Lung cancer is the number one cause of cancer-related death around the world. 1 NSCLC accounts for approximately 80-85% of lung cancers, 2 with BRAF V600E mutations occurring in about 2% of patients with NSCLC. 3 Understanding the role of the mitogen-activated protein within the pathway including BRAF V600E-mutant metastatic NSCLC. The Phase 2 PHAROS trial ( NCT03915951 ) is an open-label, multicenter, single arm study examining BRAFTOVI + MEKTOVI combination therapy in treatment-naïve and previously treated patients with BRAF V600E-mutant metastatic NSCLC. Notably, upon longer-term follow-up in previously treated patients, BRAFTOVI + MEKTOVI showed a median PFS of 9.3 months (95% CI, 6.2-24.8) and a median OS of 22.7 months (95% CI, 14.1-32.2), with a safety profile that was consistent with previous findings; no new safety concerns were identified. In this analysis, treatment-related adverse events (AEs) led to dose reduction in 26% of patients, and to permanent discontinuation in 16% of patients. Nausea, diarrhea, and fatigue remained the most common treatment-related AEs. “ These potentially practice-changing results from the PHAROS trial show that the combination of BRAFTOVI + MEKTOVI is providing long-term compelling efficacy for patients, and although no definitive conclusions can be made across trials, the duration of response and progression-free survival in treatment naïve patients appear to be the longest observed for BRAF V600E–mutant metastatic NSCLC compared with historical outcomes,” said Roger Dansey, M.D., Chief Development Officer, Oncology, Pfizer. “ These latest data reflect our deep understanding of the science behind biomarker-driven cancers and add to our legacy in developing innovative targeted treatments in NSCLC. We are continuing to build upon this strong foundation with a pipeline of targeted medicines and combinations across our tumor areas of focus, including the ongoing investigation of BRAFTOVI in earlier settings of metastatic colorectal cancer, and the exploration of a next-generation brain-penetrant BRAF inhibitor.” BRAFTOVI + MEKTOVI was approved by the U.S. Food and Drug Administration (FDA) in October 2023, and by the European Commission in August 2024, for the treatment of BRAF V600E-mutant metastatic NSCLC based on the initial ORR (the primary endpoint) and DoR (key secondary endpoint) results from the PHAROS clinical trial. In addition to PHAROS, safety lead-in data from the ongoing Phase 3 BREAKWATER study investigating BRAFTOVI in combination with cetuximab and FOLFIRI chemotherapy in previously untreated BRAF V600E-mutant metastatic colorectal cancer (CRC) will also be presented as a mini-oral session at ESMO (Abstract 515MO). BRAFTOVI in combination with cetuximab and FOLFIRI was found to be generally tolerable in this patient population, with no new safety concerns identified. These findings support the ongoing investigation of this combination regimen as a potential treatment option for BRAF V600E-mutant metastatic CRC. The Phase 3 BREAKWATER trial is ongoing, with updated data expected in 2025. BRAF mutations can occur in a number of tumor types, including metastatic melanoma, metastatic CRC and metastatic NSCLC. Among different types of BRAF mutations, the BRAF V600E mutation is particularly important as it occurs in approximately half of patients with BRAF -mutant metastatic NSCLC. 4 Further, this mutation represents up to 90% of BRAF mutations in melanoma 5 and more than doubles the risk of mortality for patients with CRC. 6 In addition to our continued investigation of BRAFTOVI + MEKTOVI for BRAF- mutant cancers, Pfizer is also exploring a next-generation BRAF inhibitor designed to selectively inhibit mutant BRAF monomers and mutant BRAF- containing dimers and be brain penetrant. The investigational drug is currently being evaluated in a Phase 1 clinical study. Pfizer has exclusive rights to BRAFTOVI + MEKTOVI in the U.S., Canada, and all countries in Latin America, Africa and the Middle East. Ono Pharmaceutical Co., Ltd. has exclusive rights to commercialize both products in Japan and South Korea, Medison has exclusive rights in Israel, and Pierre Fabre Laboratories has exclusive rights in all other countries, including Europe and Asia-Pacific (excluding Japan and South Korea). The PHAROS trial is conducted with support from Pierre Fabre Laboratories.
