Junshi shares more data of COVID-19 pill versus Paxlovid

Junshi Biosciences has shared more Phase III data of VV116, its COVID-19 oral drug, versus Pfizer's Paxlovid and said the study reached its primary endpoint and secondary efficacy endpoint.

The Phase III study compared VV116 and Paxlovid in the treatment of patients with mild to moderate COVID-19 who are at high risk for progression to severe COVID-19 including death.

The primary endpoint was “time to sustained clinical recovery,” and the secondary endpoints included “percentage of participants who had progression of COVID-19 (defined as progression to severe and/or critical COVID-19 and death from any cause) by Day 28,” “time to sustained disappearance of clinical symptoms,” and “percentage of participants who turned negative for SARS-CoV-2.

Junshi said in comparison with patients in the Paxlovid arm, those in the VV116 arm exhibited a shorter time to sustained clinical recovery and achieved statistical superiority, which demonstrates VV116’s ability to accelerate the alleviation of COVID-19 symptoms.

As for the secondary efficacy endpoints, there was no COVID-19 disease progression or death in the VV116 arm or Paxlovid arm. Junshi said researchers observed that VV116 showed a trend toward superiority to Paxlovid in the time to sustained disappearance of clinical symptoms and the time to patient testing negative for SARS-CoV-2 for the first time.

The company added that VV116 has a good safety profile and its overall incidence of adverse events is lower than that of Paxlovid. More data are to come later in a medical journal.

Junshi released a brief statement on May 23 that the study reached its primary endpoint and the company will communicate with Chinese regulators about an NDA shortly. But the positive news did not help Junshi's share price that day, which closed 16% lower instead.
