J&J begins phase 3 ENSEMBLE Covid-19 vaccine trial for JNJ-78436735

ENSEMBLE Covid-19 vaccine trial : Johnson & Johnson (J&J) has launched a multi-nation phase 3 trial called ENSEMBLE for its JNJ-78436735 Covid-19 vaccine candidate (Ad26.COV2.S), which is being developed by its subsidiary – Janssen Pharmaceutical Companies.

The US healthcare giant said that the ENSEMBLE vaccine trial has been initiated following positive interim results from its phase 1/2a clinical study. In the earlier clinical trial, the JNJ-78436735 vaccine candidate showed that the safety profile and immunogenicity after a single dose were in favor of further development.

Johnson & Johnson said that based on the findings and after discussions with the US (FDA), the ENSEMBLE Covid-19 vaccine trial will feature up to 60,000 volunteers in three continents.

It will be held across the US, Brazil, Chile, Argentina, Colombia, Mexico, Peru, and South Africa.

The phase 3 clinical trial will assess the safety and efficacy of a single vaccine dose of JNJ-78436735 in comparison to placebo in the prevention of Covid-19.
