In a first of its kind phase I trial, Rejuvenate Biomed NV has secured ethical clearance to induce acute sarcopenia in 42 healthy subjects, aged 65 to 75 years old. That will be achieved by placing a cast on one leg to induce sarcopenia through muscle disuse. The volunteers in the double-blind trial will then receive either RJx-01, an oral small molecule for treating sarcopenia, or placebo.

Jiangsu Atom Bioscience and Pharmaceutical Co. Ltd., a company developing an oral a urate anion exchanger 1 inhibitor for the potential treatment of chronic gout, said results of a phase IIa trial show that its lead candidate, ABP-671, reduced serum uric acid levels to less than 6 mg/dL, below the clinically defined threshold of 7 mg/dL for hyperuricemia, or excess of uric acid in the blood, which leads to gout.

Though conceptually understood for decades, antibody-drug conjugates (ADCs) haven’t begun to come into their own until recently, but oncology drug developers continue to wrestle with challenges, large among them the problem of antigen selection. Lately, companies including names such as Adagene Inc., Bioatla Inc. and Cytomx Therapeutics Inc., have taken particular interest in exploiting features of the cancer growth itself to add more oomph, with focus on special features of the tumor microenvironment (TME).

Medtronic plc reported its tibial neuromodulation device was implanted in the first patient with overactive bladder as part of its Titan 2 pivotal study. The device stimulates the posterior tibial nerve near the ankle to assist in regulation of bladder function. Medtronic expects to enroll 130 patients in the study.

Following another failure in amyotrophic lateral sclerosis (ALS), Biogen Inc. will discontinue its development of antisense oligonucleotide BIIB-078 with partner Ionis Pharmaceuticals Inc. The stumble is part of a mega-collaboration the two companies began 10 years ago that has also yielded a lot of success, including the blockbuster Spinraza (nusinersen).
