Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are there any noteworthy precedents involving Pegcetacoplan's use in scientific research?

"Currently, 10 clinical trials are researching Pegcetacoplan with 5 of those in the final phase. Although most studies for this treatment occur within London and California, there is a total of 576 sites conducting research on it."

Answered by AI

How many participants have signed up to take part in this clinical investigation?

"Affirmative. Data provided by clinicaltrials.gov implies that this medical investigation is presently recruiting patients; first posted on February 1st 2022 and most recently revised on October 19th, it seeks to enrol 12 volunteers at 6 distinct sites."

Answered by AI

Is there currently an open enrollment for this research endeavor?

"Affirmative. According to the information found on clinicaltrials.gov, this medical experiment is actively recruiting patients; it was first posted in February 2022 and updated most recently in October 2022. The study requires 12 participants from 6 separate sites."

Answered by AI

How many sites are currently managing this research project?

"This medical study is welcoming patients at Ryotaro Nakamura, MD in Duarte, California, Clinical Trial Site in Rochester, Minnesota and Hassan AlKhateeb, MD in Augusta Georgia. As well as four additional clinical trial centres."

Answered by AI

Has the Federal Drug Administration sanctioned Pegcetacoplan for medical use?

"Due to a lack of efficacy data, the safety rating for Pegcetacoplan is 2. This score stems from this being Phase 2 trial and hence having only some evidence that it can be safely used in patients."

Answered by AI

Is this an unprecedented clinical trial?

"As of now, 10 trials for Pegcetacoplan are taking place in 149 cities and 26 countries. This medication was first approved for testing back in 2018 by Apellis Pharmaceuticals, Inc.. The Phase 3 study included 600 participants with 8 subsequent studies concluding since then."
