Pfizer (NYSE:PFE) said its late-stage coronavirus vaccine trial has enrolled more than 42,000 volunteers, the company announced Tuesday when it released a mixed third-quarter earnings report.
It said nearly 36,000 of the volunteers have already received the second of its two-dose Covid-19 vaccine. Pfizer has as been working alongside German drugmaker BioNTech on the experimental vaccine. It contains genetic material called messenger RNA, or mRNA, which scientists hope provokes the immune system to fight the virus.
In September, Pfizer expanded the enrollment of its phase three trial to up to 44,000 volunteers from the initial target of up to 30,000. The company said the expansion would allow it to further increase diversity in the trial as well as include adolescents as young as 16 years old and people with preexisting conditions.
In an earnings slide, Pfizer said the data monitoring board, which will assess whether the trial has been successful, has not conducted an interim efficacy analyses yet.
The update on the trial comes as Pfizer reports a mixed quarter. Third-quarter sales dropped by 4.3%, hurt in part by lower demand for some of its drugs due to the pandemic.
Sales fell to $12.13 billion, down from $12.68 billion a year earlier and lower than the $12.32 billion Wall Street analysts were expecting. Still, the company’s profits were slightly better than expected at 72 cents per share, higher than the 71 cents analysts were expecting.
PFE shares doffed 38 cents, or 1%, to $37.54.
