Artificial intelligence is no longer just a supporting tool in biotechnology – it is beginning to define the way drugs are discovered, tested and advanced into the clinic, speakers said during the Bio Hong Kong conference Sept. 10 to 13.

Activity in some clinical parameters is leading Atyr Pharma Inc. to plan a sit-down with regulators, even though the tRNA synthetase-derived drug efzofitimod missed its primary endpoint of steroid tapering in the phase III Efzo-Fit study against the interstitial lung disease pulmonary sarcoidosis (PS). CEO Sanjay Shukla said his firm maintains “a high degree of conviction” regarding the candidate. “But I want to make sure we have the best briefing book possible” before consulting with the U.S. FDA, which will happen as soon as possible.

As Avidity Biosciences Inc. brought the second-largest follow-on offering of the year to the market, the company also released positive early and midstage stage results of del-zota, an antibody-oligonucleotide conjugate, in treating Duchenne muscular dystrophy. Phase I/II results showed a reversal of disease progression in patients who have been continuously treated for a year, plus improvements in several functional measures.

Remynd NV has turned in positive phase IIa data for a new target in Alzheimer’s disease, showing that restoring calcium homeostasis in neurons reduces levels of pathological tau proteins, increases dopamine levels and has a positive effect on cognition in symptomatic patients.

Two months after starting the phase I/II Synrgy trial with its gene therapy, CAP-002, enrolling 12 pediatric patients with rare disease STXBP1 encephalopathy, Capsida Biotherapeutics paused the study following the death of the trial’s first patient.

Maze Therapeutics Inc. CEO Jason Coloma said the latest phase I results with MZE-782, a prospect for phenylketonuria (PKU) as well as chronic kidney disease (CKD), bolster the firm’s “conviction to move into phase II” next year in both indications.

PMV Pharmaceuticals Inc.’s rezatapopt yielded impressive overall response data in ovarian cancer, prompting the firm to aim for a potential accelerated approval filing in early 2027. The news caused the firm’s stock (NASDAQ:PMV) to jump in premarket trading, but shares ended the day at $1.27, down 20%, as investors signaled they are clearly holding out for further data confirming broader market potential for the p53-targeting small molecule.

“New explosions in biotechnology are allowing us to interrogate cancers at a very sophisticated level compared to before,” Dennis Slamon told audience members at the Global Bio Conference in Seoul, South Korea Sept. 3.

Argenica Therapeutics Ltd. saw its stock drop 56% following mixed results for its ARG-007 phase II Seancon trial in acute ischemic stroke patients undergoing endovascular revascularization, or thrombectomy.
