Natera Inc. added its Prospera assessment for lung transplant patients to its portfolio, joining the company’s tests for rejection of kidney and heart transplants. The test uses donor-derived cell-free DNA (dd-cfDNA) to detect acute rejection as well as chronic rejection and infection in stable patients. Results of the VALID study presented at CHEST 2021 demonstrated that the Prospera Lung test had a negative predictive value of 97.33%, sensitivity of 89.06% and area under the curve of 0.91.

LONDON – Inivata Ltd. is extending efforts to bring its liquid biopsies into routine use, in two new clinical trials in lung cancer. The first will attempt to show increased speed in getting advanced non-small-cell lung cancer (NSCLC) patients on to the most appropriate therapies. The second study aims to demonstrate that detecting circulating tumor DNA (ctDNA) will single out those early-stage lung cancer patients who have residual or recurring disease after surgery and need further treatment with chemo- or immuno-therapies.

Based on positive phase IIb data from 2020 for avasopasem manganese (GC-4419) in treating severe oral mucositis (SOM) in patients with locally advanced head and neck cancer, Galera Therapeutics Inc. had been confident about phase III data for the selective small-molecule dismutase. However, the phase III Roman trial failed to hit its primary endpoint of reduction in the incidence of SOM. Mel Sorensen, Galera’s CEO, expressed his surprise at the results and said the company is evaluating the next steps for the program.

Baidu Inc.’s preclinical studies showed the mRNA vaccine sequences for COVID-19 designed using its Lineardesign algorithm outperformed the benchmark sequences designed by traditional algorithms in terms of stability, protein expression and immunogenicity. The firm teamed up with Stemirna Therapeutics Co. Ltd., which specializes in the R&D of mRNA vaccines and drugs, to test seven mRNA COVID-19 vaccine sequences designed using Lineardesign.

Top-line results of a phase III trial testing sulbactam-durlobactam, a combination beta-lactam antibiotic and beta-lactamase inhibitor, in patients with carbapenem-resistant Acinetobacter baumannii infections, found the novel combo to be statistically noninferior to colistin in 28-day all-cause mortality, the study's primary endpoint.

A genetic biomarker-based diagnostic test developed by Inbiomotion SL to identify treatment for early-stage breast cancer could significantly improve patient survival, a study has found. Data from the phase III NSABP-B34 study published in the Journal of the National Cancer Institute Cancer Spectrum, showed that in patients with MAF-negative (mutation biomarker) tumors – determined with Inbiomotion’s MAF Test – adjuvant treatment with clodronate was associated as having the greatest benefit compared to placebo-treated control patients receiving the same standard of care.

Thanks to positive phase III data from Phathom Pharmaceuticals Inc.’s Phalcon-EE study of patients with erosive esophagitis, the company is prepping to file an NDA with the FDA for its lead compound, vonoprazan.
