Figure 1 Kaplan-Meier curve showing proportion of patients who discontinued clofazimine over time due to all causes: ADRs, culture conversion (cleared), death/lost to follow-up, treatment failure, or who are still taking clofazimine. Twenty-two (20%) were still taking clofazimine at the time of analysis. Overall, 16 patients stopped due to a certain (n = 3), probable (n = 9), or possible (n = 4) ADR after a median of 101 days (95% CI, 63-119). ADRs = adverse drug reactions.

Figure 2 Kaplan-Meier curve showing proportion of patients who discontinued clofazimine over time according to each category of ADRs. Six patients stopped due to GI ADRs only (median, 86 days [95% CI, 61-285]), five stopped due to GI ADRs plus either skin or neurologic/constitutional ADRs (94 days [95% CI, 3-289]), and two stopped due to skin-related ADRs (167 days [95% CI, 119-214]). One patient each stopped due to allergy, dizziness, and laboratory test abnormality. See Figure 1 legend for expansion of abbreviation.

Figure 3 Change in FEV1 % predicted (n = 15) with clofazimine for responders (red) and nonresponders (blue). Mixed model analysis of FEV1 in the 2 years prior to and 2 years following clofazimine initiation is shown. Nonresponders had a significant worsening of decline following the addition of clofazimine (mean ± SE, –5.3% ± 1.3% per year [P < .01]; change in slope, –3.3 ± 1.8 [P = .04]). Responders showed an improvement in FEV1 % predicted decline posttreatment (–1.3% ± 1.5% per year [P = .27]; change in slope, 2.3% ± 2.1% [P = .29]). Post-clofazimine slope and change in slope with initiation of clofazimine in responders was significantly different than nonresponders (–1.3% ± 1.5% vs –5.3% ± 1.3% per year [P = .04]; 2.3% ± 2.1% vs –3.7% ± 1.8% [P = .03]), respectively).
