Phase 1
Recruiting
Conditions
Nontuberculous Mycobacterium Infection
Interventions
Registration Number
NCT04294043
Lead Sponsor
Chris Goss
Brief Summary

The purpose of this study is to assess the safety and tolerability of two 5-day infusion cycles of IV gallium in adult patients with CF who are infected with NTM.

Funding Source - FDA Office of Orphan Products Development (OOPD)

Detailed Description

This is a prospective, multicenter open-label study in adults with CF who are colonized with M. avium complex and/or M. abscessus complex.

Participants are enrolled into one of the two cohorts:

1. Treatment-Naïve NTM Cohort: participants with persistently positive NTM culture results (either M. avium complex, M. abscessus complex, or both M. avium and M. abscessus) who had never been treated for current NTM species or previous treatment was associated with clearance of NTM.

2. Treatment-Refractory NTM Cohort: participants with persistently positive NTM culture results (either M. avium complex, M. abscessus complex, or both M. avium and M. abscessus) whose treatment failed to respond to 12 months of NTM guideline-based therapy or currently receiving treatment with guideline-based antibiotics for \> 12 months.

Subjects will receive two 5-day infusion cycles of IV gallium. The study will evaluate the safety and antimycobacterial effect of two 5-day infusions of IV gallium.

Infusion of IV GalliumGallium nitrateGallium nitrate will be infused continuously over 5 days at 200 mg/m2/day. Study drug will be administered via a peripheral IV catheter, a peripherally inserted central catheter (PICC) line, midline catheter, or a chronic indwelling vascular access device using an ambulatory infusion pump infused over 24 hours for 5 sequential days for each cycle. There is a maximum of 2 cycles.
Primary Outcome Measures
NameTimeMethod
Adverse Events of Special InterestBaseline to Day 57

Proportion of patients experiencing one or more Adverse Events of Special Interest (AESI). AESIs include the occurrence of either (1) a serious adverse event (SAE) of grade 3 or higher including hospitalizations or (2) study drug discontinuation because of an AE.

Secondary Outcome Measures
NameTimeMethod
NTM clearance (efficacy)Day 6 to Day 111

Proportion of subjects who were NTM culture positive at baseline and have at least 2 sequential negative NTM cultures between visits 2 (Day 6) and 7 (Day 111). Those negative cultures must be at least 2 weeks apart.

Clinically significant abnormal laboratory measures. (safety)Baseline to Day 57

Proportion of patients experiencing clinically significant abnormal laboratory measures. Clinically significant abnormal laboratory measures are identified by the site investigator.
