BioWorld tracked 262 clinical trial readouts across phases I through III in May 2026, the highest monthly total so far this year and well above April’s 143, March’s 209, February’s 152 and January’s 144. By phase, BioWorld recorded 98 phase I readouts in May, 81 in phase II and 83 in phase III. Of the phase III programs, 17 trials posted positive results, and one failed to meet its primary endpoints.

Otsuka Pharmaceutical Co. Ltd. reported another clinical study win with once-daily centanafadine, a non-stimulant compound targeting attention deficit hyperactivity disorder (ADHD).

Nature Medicine has retracted a widely publicized Chinese lung cancer study that suggested administering immunotherapy before 3 p.m. could dramatically improve survival in a decision that comes amid heightened scrutiny of research integrity and data transparency in high-impact biomedical journals.

The field of BCI is continually evolving; as such, companies are increasingly highlighting the potential of their technologies to transform care. For advanced players, with fully developed BCI systems, the sector is approaching an inflection point as the technology transitions from early feasibility studies into pivotal trials. The focus now for many is on generating the long-term safety, efficacy and real-world usability data needed to support regulatory approval and broader clinical adoption.

Corxel Pharmaceuticals Ltd.’s oral small-molecule GLP-1 receptor agonist, CX-11, met the primary endpoints in a phase II trial evaluating the candidate in obese and overweight patients in the U.S., according to top-line results.

Neither of Cynata Therapeutics Ltd.’s pivotal trials for its Cymerus stem cell platform met the primary endpoints, with no statistically significant differences between active and control groups on primary or key secondary efficacy measures, CEO Kilian Kelly told investors during a June 22 conference call.

J-Pharma Co. Ltd. is progressing the most clinically advanced L-type amino acid transport 1 (LAT1) inhibitor, nanvuranlat (JPH‑203), in a global phase III Beacon-BTC study of biliary tract cancer following U.S. FDA alignment.

Decades of research are helping unravel the “black box” of the brain. The second article in BioWorld’s series on the Brain-Computer Interface (BCI) field looks at how simultaneous breakthroughs in AI technology are pushing the BCI field from a theoretical concept to a potential real-world, clinical option for individuals, particularly in China where the National Medical Products Administration greenlighted the world’s first invasive BCI system – Neuracle Medical Technology Co. Ltd.’s Neural Electronic Opportunity – for clinical use in March 2026.

Missing statistical significance on the primary overall survival phase III endpoint with antibody-drug conjugate (ADC) sigvotatug vedotin compared with docetaxel in non-small-cell lung cancer (NSCLC), Pfizer Inc., which gained the candidate through its $43 billion buyout of Seagen Inc. in 2023, is forging ahead based on subgroup signals, phase I data and an ongoing phase III Keytruda combination effort currently underway.

Neither of Cynata Therapeutics Ltd.’s pivotal trials for its Cymerus stem cell platform met the primary endpoints, with no statistically significant differences between active and control groups on primary or key secondary efficacy measures, CEO Kilian Kelly told investors during a June 22 conference call.
