Drug Intended To Ease Fatal Cytokine Storms Shown To Not Benefit Severely Ill Patients Who Aren’t On Ventilators
There is still a glimmer of a positive result in the study of patients given the arthritis drug sarilumab, sold as Kevzara, for critically ill COVID-19 patients. Trials for that group of patients will continue.

Arthritis Drug Did Not Help Seriously Ill Covid Patients, Early Data Shows
Doctors around the world, trying to save seriously ill coronavirus patients, have been dosing them with rheumatoid arthritis drugs that can squelch immune responses. The theory was that many were dying because their immune systems went into overdrive, creating a fatal storm that attacked their lungs. But now, preliminary results on treatments with one of these drugs, sarilumab, marketed as Kevzara and made by Regeneron and Sanofi, indicate that it does not help patients who are hospitalized but not using ventilators.

Drug Study Halted Early For Certain Covid-19 Patients After No Benefit Seen
The study will continue, however, for an even sicker set of hospitalized Covid-19 patients who require the help of ventilators or other high-flow oxygen support, the companies said. In the second, sicker group of patients, the drug showed a relatively small potential benefit over placebo—substances with no actual pharmaceutical effect—though that will need to be confirmed in the ongoing study, the companies said. Results are expected in June. “There’s still hope it might help, but more modest than people hoped,” Regeneron Chief Scientific Officer George D. Yancopoulos said. “It doesn’t look like the magic panacea that everyone would’ve wanted for the pandemic.” (Walker, 4/27)

Closely Watched Arthritis Drug Disappoints As A Covid-19 Treatment
Kevzara was not expected to directly block the coronavirus, SARS-CoV-2, that is causing a global pandemic. But it was hoped that the drug would help ease the immune system’s overreaction to the virus — a “cytokine storm” that causes inflammation and fluid buildup in the lungs of many of the sickest patients — potentially helping to keep patients off of ventilators or saving their lives. Early data from a 21-patient study in China using Actemra had appeared promising. (Herper, 4/27)

Experts Worry Next Studies Of Gilead Covid-19 Drug May Add Uncertainty
For weeks, the world has been eagerly awaiting clinical trial results for one experimental drug, remdesivir, to treat Covid-19. On some days, the entire stock market has moved up and down based on limited amounts of data about the therapy from Gilead Sciences. The signals, so far, have been contradictory.
