Researchers from Chonnam National University presented novel a doxycycline (Doxy)-inducible gene switch system in attenuated Salmonella typhimurium, one of the bacterial strains that has been previously shown to selectively colonize and multiply in tumors, leading to oxygen deprivation, excessive nutrient leakage, and an antitumor immune response.
Survival in metastatic breast cancer has increased in recent years, but 5-year survival rates remain below 50% and the mechanisms of spreading remain to be elucidated. An emerging strategy to inhibit the progression of tumors consists of acting on tumor-associated macrophages to displace them from an M2-like phenotype to an M1-like phenotype.
Several metabolic alterations, including a preferential use of aerobic glycolysis, facilitate autonomous proliferation and survival of tumor cells. Although previous research suggested that active glycolysis in tumor cells is closely linked to genetic alterations, the underlying regulatory mechanisms remained unknown.
Researchers from University of California Los Angeles and affiliated organizations published data from a study that aimed to identify novel surface proteins that are highly and selectively expressed in tumors and could serve as targets for chimeric antigen receptor (CAR) T-cell therapies for the treatment of melanoma.
The first – and handsomely upsized – IPO of this year by CG Oncology Inc., along with the sizeable financing Feb. 14 by Engene Holdings Inc., proved Wall Street’s interest in non-muscle invasive bladder cancer, where a number of other players also are busy.
Amid intensifying competition in the PD-1/PD-L1 checkpoint space, Samsung Bioepis Co. Ltd. kicked off a phase I study of SB-27, a biosimilar of Merck & Co Inc.’s blockbuster immunotherapy, Keytruda (pembrolizumab), for lung cancer. Posted on clinicaltrials.gov on Feb. 20, the randomized, double-blind, three-arm, parallel group and multicenter phase I study will examine the pharmacokinetics, efficacy and safety of SB-27 against an EU-sourced and U.S.-sourced Keytruda in 135 patients with non-small-cell lung cancer.
The aryl hydrocarbon receptor (AhR) is a transcription factor that modulates the activity of tumor and immune cells, hence targeting AhR may represent a feasible option for cancer immunotherapy. Researchers from the Institute of Materia Medica of Beijing and collaborators recently reported on the discovery and synthesis of a novel series of AhR antagonists derived from Salvia miltiorrhiza Bunge intended to be used in cancer immunotherapy.
Monopar Therapeutics Inc. has received human research ethics committee (HREC) clearance in Australia to commence a first-in-human phase I dosimetry trial of its novel radiopharmaceutical MNPR-101-Zr in patients with advanced cancers.
