Low Dose Trimethoprim-Sulfamethoxazole for the Treatment of Pneumocystis Jirovecii Pneumonia

Todd C. Lee MD MPH FIDSA·interventional·Posted Apr 20, 2021·Updated Feb 20, 2026

In Brief

A Phase 3 clinical trial evaluating trimethoprim-sulfamethoxazole for Pneumocystis and 7 related conditions. Currently recruiting, targeting 416 participants across 1 site.

Detailed Summary

Pneumocystis jirovecii pneumonia (PCP) is an opportunistic fungal infection of immunocompromised hosts which causes in significant morbidity and mortality. The current standard of care, trimethoprim-sulfamethoxazole (TMP-SMX) at a dose of 15-20 mg/kg/day of TMP, is associated with serious adverse events, including hypersensitivity reactions, drug-induced liver injury, cytopenia, and renal failure occurring among 20-60% of patients. The frequency of adverse events increases in a dose dependent manner and commonly limits the use of TMP-SMX. Reduced treatment doses of TMP-SMX for PCP reduced ADEs without mortality differences in a recent meta-analysis of observational studies. We therefore propose a Phase III randomized, placebo-controlled trial to directly compare the efficacy and safety of low dose (10 mg/kg/day of TMP) compared to the standard-of-care (15 mg/kg/day) among patients with PCP for the primary outcome of Win Ratio hierarchical composite of death, ECMO, invasive ventilation, grade 4 toxicity, non-invasive ventilation, change of therapy and length of stay.
