Description of intervention(s) / exposure
MNKD-101 is an inhalation suspension of clofazimine (CFZ) for the treatment of infections with pulmonary nontuberculous mycobacteria (NTM) both with and without cystic fibrosis.
The study consists of 2 parts.
Part A (Single Ascending Dose): The study will investigate the safety, tolerability, and pharmacokinetics of MNKD-101.
The participants will be allocated in a randomized and double-blind manner at a ratio of 3:1 to receive MNKD-101 or placebo inhalation (6 MNKD-10 :2 placebo)
In total 3 cohorts will be investigated and the dose level for each cohort may be changed based on available data and following Safety Monitoring Committee review. The maximum increment will be 30 mg CFZ (1.5ml MNKD-101) nominal per dose step and the maximal dose will be of 90 mg CFZ (4.5ml MNKD-101) nominal fill dose.
Cohort A1: 30 mg CFZ (1.5ml MNKD-101) single inhaled dose using a nebulizer on Day 1
Cohort A2: 60 mg CFZ (3.0ml MNKD-101) single inhaled dose using a nebulizer on Day 1
Cohort A3: 90 mg CFZ (4.5ml MNKD-101) single inhaled dose using a nebulizer on Day 1
Each cohort consist of distinct group of participants
Part B (Multiple Ascending Dose): The study will investigate the safety, tolerability, and pharmacokinetics of MNKD-101.
In total 2 cohorts will be investigated and the participants will be randomized in a double-blind manner in a 3:1 ratio to receive daily doses of active or placebo treatment for 1 week
Cohort B1: 30 mg CFZ (1.5ml MNKD-101) inhaled multiple ascending daily doses using a nebulizer at the same time each day from Day 1 to Day 7
Cohort B2: The inhaled multiple ascending daily doses administered using a nebulizer to be in Cohort B2 will be determined based on safety and pharmacokinetic data from Part A and Cohort B1
Each cohort consist of distinct group of participants
Part B will commence after the completion of Part A of the study. The decision to commence Cohort B2 and the dose to be administered will be determined by the Safety Monitoring Committee following review of all available safety and pharmacokinetics data from Part A (SAD) and the 7-day safety and pharmacokinetic data from Cohort B1.

Each inhalation will be closely monitored by an unblinded member of the study team, to ensure proper inhalation. Therefore, adherence monitoring for Part A and B is done by the study nurse observing the inhalation.
Intervention code [1] 322024 0
Treatment: Drugs
Comparator / control treatment
The placebo will comprise isotonic saline (0.9% w/v sodium chloride).
Mode of administration: Inhaled dose using a nebulizer
Control group
Placebo

Primary outcome [1] 329328 0
Part A/Part B: To evaluate the safety and tolerability of single and multiple ascending doses of MNKD 101 in healthy adult participants
To be assessed by monitoring
• Incidence, frequency, severity, and duration of treatment-emergent adverse events (TEAEs)
• Incidence, frequency, severity, and duration of serious adverse events (SAEs)
• Vital signs (heart rate, blood pressure, respiratory rate and tympanic temperature)

Timepoint [1] 329328 0
Part A: The TEAEs and SAEs are monitored at each intervention timepoint, vital signs continuously monitored from Baseline to Day 43 post dose
Part B: The TEAEs and SAEs are monitored at each intervention timepoint, vital signs continuously monitored from Baseline to Day 57 post dose
Secondary outcome [1] 402153 0
Part A/ Part B: To evaluate the plasma pharmacokinetics (PK) of MNKD-101 following single and multiple ascending doses in healthy adult participants
The following parameters are used to evaluate the pharmacokinetics
• Maximum plasma MNKD-101 concentration (Cmax)
• Time to maximum concentration (Tmax)
• Terminal elimination half-life (t1/2)
• AUC from time zero (from the start of inhalation time) to the last measurable concentration (AUC0-t)
