APOLLO: A Randomized, Double-Blind, Placebo-Controlled Study of Bitopertin to Evaluate the Efficacy, Safety, and Tolerability in Participants with Erythropoietic Protoporphyria (EPP) or X-Linked Protoporphyria (XLP)

The APOLLO study is testing a new daily tablet called bitopertin for adults with EPP or XLP. These rare conditions cause severe skin pain in sunlight. Researchers want to see if bitopertin can reduce this pain and allow people to spend more time outdoors safely over six months.
