Study Summary

This trial is testing a new treatment for a lung disease caused by nontuberculous mycobacteria. The treatment is a drug called recombinant Interleukin-7 (IL-7), and this trial is testing two different dose levels to see how well it works and if it is safe.

Eligible Conditions
  • Mycobacterium abscessus Infection

Eligibility Criteria

Age 18+ · All Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
in the study People aged 18 to 85 who have given written consent to participate in a study are eligible to participate in the study.
Women who could potentially get pregnant must have a negative pregnancy test within 24 hours of starting the study treatment.
Women who could potentially become pregnant must agree to use a method of birth control for the entire time they are taking CYT107, plus 5 half-lives of CYT107 (which is up to 2 days), plus 30 days (the length of a typical ovulatory cycle) for a total of 2 months after they have finished taking CYT107.
This study allows a participant who may have been discontinued as a pre-treatment screen failure to be re-enrolled.
Males who are sexually active with WOCBP must agree to use contraception during treatment with CYT107 plus 5 half-lives of CYT107 plus 90 days (duration of sperm turnover) for a total of 7 months post-treatment completion
The patient is currently on a stable guideline-based therapy that has not changed for the past 28 days
in public Women are not allowed to breastfeed in public.
You have a positive sputum culture for Mycobacterium tuberculosis after 6 months of GBT, with at least one positive sputum culture within 2 months prior to the baseline visit.
You are able to produce at least 3 mL of sputum or you are willing to undergo an induction to produce at least 3 mL of sputum for clinical evaluation.
