What was measured

Number of participants with ADA positive against PF-06801591 after IV and SC dosing - Part 1 and Part 2. A participant was ADA positive if (1) baseline titer was missing or negative and participant had ≥ 1 post-treatment positive titer (treatment-induced), or (2) positive titer at baseline and had a ≥ 0.602 in titer from baseline in ≥ 1 post-treatment sample (treatment-boosted). Participants who were ADA positive at baseline but did not become boosted post-treatment were considered as ADA negative.

Analysis population: Analysis population included all participants who received at least 1 dose of study treatment and had at least 1 post-treatment ADA result.
