Clinical data in 2021 has risen by about 9.2% in comparison with the same timeframe in 2020. As of mid-August, BioWorld has tracked a total of 2,400 entries of clinical data, which is up from the 2,197 entries last year.

Astrazeneca plc and Daiichi Sankyo Co. Ltd. are pushing forward with a challenge to Roche Holding AG with breast cancer drug Enhertu (trastuzumab deruxtecan) after it demonstrated superiority over the Swiss firm’s Kadcyla (trastuzumab emtansine) in a head-to-head trial.
Jiangsu Hengrui Medicine Co. Ltd. reported positive interim data from its phase III trial for SHR-3680, an androgen receptor antagonist, demonstrating that it reduced the risk of disease progression or death in metastatic hormone-sensitive prostate cancer patients with high-volume disease burden.

Medigen Vaccine Biologics Corp. released results from a phase III trial of its enterovirus 71 (EV71) vaccine that showed efficacy of 100% against a virus that causes hand, foot and mouth disease and continues to emerge on a regular basis across Asia.

The data built on positive data released in August from another phase III study showing sugemalimab (CS-1001) prolonged PFS when used as a first-line treatment for stage IV squamous and nonsquamous NSCLC plus standard-of-care chemotherapy, hitting the study’s primary endpoint.
HONG KONG – Following a wave of concern about the efficacy of two COVID-19 vaccine candidates developed by China National Pharmaceutical Group (Sinopharm), interim analysis of an ongoing phase III trial, published May 26 in the Journal of the American Medical Association, has shown that adults receiving at least one dose of either of the company’s two inactivated SARS-CoV-2 vaccines had significantly reduced the risk of symptomatic COVID-19.
The volume of phase I-III clinical trial data so far in 2021 is a full 26% more than it was by this point last year, yet the proportion of news focused on the COVID-19 pandemic continues at much the same rate.
