The interim analysis showed the drug improved outcomes as an adjuvant therapy following surgery and chemotherapy. At the time of the analysis, data on overall survival were immature.
AstraZeneca Plc has issued fresh data from its US Phase 3 trial of a Covid-19 vaccine developed jointly with Oxford University (AZD1222) showing an efficacy rate of 76% against symptomatic disease. The primary efficacy analysis included the accrual of 190 symptomatic cases of Covid-19 from the 32,449 trial participants. This represents an additional 49 cases as compared with an interim analysis of the trial which was published on 22 March and showed an efficacy rate of 79%.
A new radiotherapy for advanced prostate cancer has delivered positive results in a Phase 3 trial when compared with a standard of care for the disease, Novartis announced on 23 March. Lu-PSMA-617 met both primary endpoints of the trial, improving both overall survival and radiographic progression-free survival. The trial enrolled patients whose disease had progressed following prior taxane and androgen receptor-directed therapies.
Roche has stopped dosing patients in a Phase 3 study of an investigational drug for Huntington’s disease, a rare genetic condition that causes nerve cells in the brain to break down. The drug, tominersen, is an antisense therapy designed to reduce the production of all forms of huntingtin protein, including its mutated variant. The trial was the largest study to date in patients with this disease.
An independent data and safety monitoring board (DSMB), which had oversight over AstraZeneca’s latest Covid-19 vaccine trial, has expressed concern that the company may have included outdated information from the trial when it reported an efficacy rate of 79% for the vaccine on 22 March.

The Astra Zeneca/Oxford University vaccine (AZD1222) has shown an efficacy rate of 79% in preventing symptomatic Covid-19 disease and 100% efficacy at preventing severe disease and hospitalisation, AstraZeneca announced on 22 March.

Speaking to reporters, company executives said data from the trial will be filed shortly with the Food and Drug Administration with a view to gaining an emergency authorisation and starting US distribution soon thereafter.
