Fig. 4: Effects of pepinemab treatment on CGIC in EM cohort B1.

a, Observed categorical CGIC values at visit 17 for the entire EM cohort B1 CGIC analysis population, and in two subgroups stratified by baseline TFC value (that is, 11 and 12–13). b, Observed categorical CGIC in the subgroups stratified by TFC value over the study duration. The CGIC is a seven-point Likert scale, ranging from very much worse (−3) to very much improved (+3). Values were set to −3 following a patient death adjudged by a blinded data review committee to be related to Huntington’s disease. P values determined by one-sided Fisher’s exact test; odds ratio (95% CI) are also shown.
