Antibody-drug conjugate (ADC) specialist Ona Therapeutics SL has closed an oversubscribed series B at $86.6 million, as clinical development of the lead program ONA-255 in advanced treatment-resistant breast cancer gathers steam.

Achieving high marks in the phase II Amplify-BD trial for bipolar I and II depression, Autobahn Therapeutics Inc.’s elunetirom, a brain-penetrant central nervous system thyroid hormone receptor agonist, or thyromimetic, is moving toward a registrational path and a clinical readout in major depressive disorder.

Innovent Biologics Co. Ltd.’s Claudin18.2-targeted antibody-drug conjugate (ADC), arcotatug tavatecan (IBI-343, TAK-921), met the primary endpoint in the international multicenter phase III G-Hope-001 trial in advanced gastric cancer, according to interim results.

ADC Therapeutics SA blamed patients’ advanced age on the death imbalance in the phase III Lotis-5 confirmatory trial testing Zynlonta (loncastuximab tesirine-lpyl) in combination with rituximab to treat relapsed or refractory diffuse large B-cell lymphoma (r/r DLBCL). Whatever the reason, Wall Street wasn’t pleased and shares (NYSE:ADCT) closed June 4 at $1.32, down 57%, or $1.77.

D&D Pharmatech Inc. announced May 27 positive top-line tissue biopsy results of zabopegdutide (DD-01) from a 48-week phase II study of metabolic dysfunction-associated steatohepatitis (MASH), pushing company shares up 30% on the day.

New data from Grail Inc.’s randomized study of its Galleri multicancer early detection test could not alter the fact that the U.K. trial missed the primary endpoint of reducing the number of cancers diagnosed at stage III and stage IV. But the company is now suggesting that discounting the initial screen, when most late stage cancers were detected, would be more representative of a real-life steady state screening program.

Turn Therapeutics Inc. made public strongly positive findings from an interim analysis that involves the first 50 subjects in the ongoing phase II atopic dermatitis (AD) trial with IL-36 inhibitor GX-03.

The much-awaited phase III readout from Oculis Holding AG’s OCS-01 in diabetic macular edema (DME) fell short of expectations, delaying the possibility of a topical eye drop option for DME patients and prompting the company to shuffle its pipeline priorities, with a focus on late-stage programs targeting optic neuropathies and dry eye disease.
