Grand Rounds April 14, 2023: RECOVER in Action – Status of Clinical Trial Protocols (Kanecia Zimmerman, PhD, MD, MPH)

Rethinking Clinical Trials

There are many hypothesized causes that may co-exist in the same patient, such as persistent virus or antigens, reactivation of other viruses, uncontrolled immune responses, damage to a wide range of organs and tissues, and injury to blood vessels and abnormal blood clotting. It’s all over the place.

China’s NMPA accepts IND for SinoMab BioScience’s SM17 to treat asthma

Pharmaceutical Technology

It can suppress Th2 immune responses by binding to IL-17RB on Type 2 innate lymphoid cells (ILC2s). This blocks a cascade of responses that are induced by interleukin-25 (IL-25), a critical cytokine which is classified as ‘alarmin’.

Flow cytometry: advantages in immunotherapy clinical trials

Pharmaceutical Technology

Patients provide blood samples for clinical trial sponsors to develop and deliver these emerging immunotherapies. Flow cytometry (FCM) is the primary method scientists use to monitor immune responses in clinical trials, primarily because of its power, speed, and ability to provide a comprehensive view of a disease’s macro-environment.
