Summary

The purpose of this study is to determine if nikkomycin Z is safe when administered at different dose levels for 14 days. The study will also determine blood levels and urinary excretion of nikkomycin Z in relation to dose administered. Patients with mild forms of Valley Fever pneumonia will be eligible to participate and will be allocated to receive treatment with nikkomycin Z (various doses) or a placebo. A secondary goal of this study is to evaluate the effectiveness and dose response of nikkomycin Z in an exploratory analysis.

Conditions

  • Coccidioidomycosis

Interventions

DRUG

nikkomycin Z

Stage I: Multiple rising doses. Doses packaged on a unit dose basis in 50 and 250 mg capsules. Subjects take 1-3 capsules per dosing block for 14 days unless ADE or study withdrawal. Dose escalation unless a dose-limiting adverse effect is noted. Subjects assigned to BID dosing will receive 28 doses and subjects assigned to TID dosing will receive 42 doses. * 50 mg BID (n=4) vs placebo capsule BID (n=1) * 50 mg BID (n=4) vs 250 mg BID (n=4) vs Placebo capsule BID (n=2) * 250 mg BID (n=4) vs 500 mg BID (n=4) vs Placebo capsule BID (n=2) * 500 mg BID (n=4) vs Placebo capsule BID (n=1) At least 4 subjects complete lower dose before randomization includes next higher dose. Stage II will be a single dose level selected based on pharmacodynamics and safety from Stage I for 20 additional subjects using 4:1 randomization.
