Week of November 9
This weekly post looks to identify important advancements in the areas of oncology, CNS disorders and neurodegeneration, technologies, and industry and corporate developments. More in-depth reading and analysis can be found in the attached links.
Oncology
FDA removed its clinical hold on Poseidon Therapeutics CAR-T therapy Phase 1 trial to treat metastatic castration-resistant prostate cancer after agreeing to protocol amendments to increase patient compliance and safety. Link
Results from Jounce Therapeutics’ Phase 2 trial evaluating their ICOS-activating vopratelimab in combination with ipilimumab (Yervoy) to treat PD-L1-resistant NSCLC failed to meet pre-specified interim criteria to continue patient enrollment. Link
Allogene Therapeutics announced that they will present clinical results at the upcoming Annual Meeting of the American Society of Hematology (ASH) of their three allogeneic CAR T-cell therapies. Of note, the Phase 1 dose-escalation trial for their anti-BCMA allogeneic CAR T-cell therapy found that 2 out of 15 multiple myeloma patients were MRD negative while over a quarter of patients had Grade 3 or higher adverse events.

Also presenting at ASH, Eli Lilly and Loxo Oncology announced they will present Phase 1/2 results of their highly selective, non-covalent Bruton's tyrosine kinase (BTK) inhibitor, LOXO-305, in different non-Hodgkin lymphomas. LOXO-305 specifically targets BTKs with C481 mutations, the most common mutation after acquiring resistance to currently available BTK inhibitors. Link
CNS Disorders and Neurodegeneration
Biogen announced that the FDA advisory committee voted against approval for aducanumab to treat patients with Alzheimer’s disease. Based on the results from two Phase 3 trials, the committee almost unanimously did not find strong evidence that aducanumab is efficacious or reduces Alzheimer’s disease pathophysiology. Link
In response to a written response from the Center for Biologics Evaluation and Research (CBER) at the FDA, Sarepta Therapeutics announced it will adapt their plans for a large, multi-center Duchenne muscular dystrophy (DMD) trial evaluating its investigational gene transfer therapy into an open-label study enrolling up to 10 DMD patients. The study will evaluate the safety and expression of commercial process material for SRP-9001. Link
Technologies
While the industry focuses on developing lentivirus or AAV based gene therapies, Orchard Therapeutics developed a gammaretroviral vector-based gene therapy to treat patients. However, one of the known risks associated with gammaretroviral vectors is leukemia. Recently, Orchard Therapeutics came under investigation after a patient treated with the gammaretroviral vector-based gene therapy, administered through a compassionate use program, was diagnosed with leukemia.

Industry and Corporate Developments
Merck announced the acquisition of VelosBio, which is focused on developing receptor tyrosine kinase-like orphan receptor 1 (ROR1) antibody-drug conjugate (ADC), for $2.75 B. The main driver of this deal is VelosBio’s lead candidate, VLS-101, which is being evaluated in Phase 1 for hematological malignancies and a Phase 2 clinical trial for solid tumors. Link
Homology Medicines received $60M in investment from Pfizer for their lead gene therapy candidates to treat rare metabolism disorders. Homology’s HM-102 received Fast Track Designation and orphan drug designation from the FDA and EMA to treat adults with phenylketonuria (PKU). Link
