Sio Gene Therapies Inc. is retrenching the business as it terminated the company’s AXO-Lenti-PD license agreement with Oxford Biomedica plc for treating Parkinson’s disease. Also, Sio’s CEO, Pavan Cheruvu, is leaving the company. Sio said it is deprioritizing its Parkinson’s disease program due to several factors, including resource requirements and development timelines “to reach meaningful value inflection for the program and an increasingly challenging market and regulatory environment” for the indication.

Last week, Incyte Corp. said it was pulling its NDA seeking accelerated approval for the PI3K-delta inhibitor parsaclisib in three non-Hodgkin lymphoma subtypes, a move that followed recent decisions by Gilead Sciences Inc. and Secura Bio Inc. to withdraw from U.S. commercialization their respective PI3K-delta inhibitors in indications for which they’d received accelerated approval. But the recent spate of headlines is hardly “a condemnation” on the entire class of drugs, said Dan Gold, CEO of MEI Pharma Inc., which is aiming for a potential accelerated approval filing of its own PI3K-delta drug, zandelisib, this year.

LONDON – After six years in development, EMA’s new clinical trials information system (CTIS) was switched Jan. 31, bringing to life a law enacted in 2014 to create a single, harmonized regulatory system across the EU. As the embodiment of the Clinical Trial Regulation, CTIS will underpin a long-awaited simplification of the process for approving trials. Rather than separate applications to different national regulators, a single application delivered via CTIS can lead to simultaneous regulatory and ethics approvals in up to 30 countries.

Mighty Libtayo has stumbled. Because Regeneron Pharmaceuticals Inc. and Sanofi SA couldn’t find common ground with the FDA on postmarketing studies, the two are voluntarily withdrawing the sBLA for Libtayo (cemiplimab-rwlc) as a second-line treatment for advanced cervical cancer. Discussion about the matter continues outside the U.S., the companies said.

Oric Pharmaceuticals Inc.’s preclinical data at last December’s meeting of the American Society of Hematology didn’t please everyone but infused the CD73 drug space with more rationale for the target, and a number of other prospects continue to move through pipelines. Previous early stage findings also have suggested favorable knockdown of adenosine in comparison to Astrazeneca plc’s oleclumab and Arcus Biosciences Inc.’s small molecule, AB-680, also known as quemliclustat. Companies developing CD73 therapies also include Corvus Pharmaceuticals Inc. and Novartis AG.

Cue Biopharma Inc.’s Kenneth Pienta, acting chief medical officer, called “very strong” the latest phase Ib data with IL-2-based candidate CUE-101 in HPV-positive, recurrent head and neck squamous cell carcinoma (HNSCC), and “by midyear, we're going to have enough data to go forward to talk to the FDA to develop a strategy with them” for a registrational study, likely in third-line patients. Meanwhile, Wall Street sifted through the latest findings from Cambridge, Mass.-based Cue, which closed (NASDAQ:CUE) at $7.99, down $2.61, or 24%. The stock had been posting a gradual run-up for several days.

PERTH, Australia – As COVID-19 infections in Australia continue to mount, a dozen or so Australian compounds are winding their way through the pipeline that could offer additional protection to the vaccines and antivirals that are already provisionally approved by Australia’s Therapeutic Goods Administration.

Nearly two years after Gilead Sciences Inc. spent $4.9 billion to buy Forty Seven Inc. and its lead candidate, magrolimab, the FDA clamped a partial clinical hold on five of Gilead’s clinical trials combining the therapy with azacitidine. The cause, according to Gilead’s management, is “an apparent imbalance in investigator-reported suspected unexpected serious adverse reactions between study arms.” The company said it has not identified a clear trend in the adverse reactions or new safety signals.
