Brief summary

This is a first in human study for MAP 315 designed to investigate the safety, tolerability and pharmacokinetics of multiple doses of MAP 315 in healthy adult volunteers. The pharmacodynamic effects of MAP315 will also be explored. The active ingredient of MAP 315 is a live bacterium that is a common member of the gut microbiome of healthy adults. MAP315 is being developed for the treatment of Ulcerative colitis. It is a randomised, double-blind and placebo-controlled study conducted at a single clinical trial centre with a satellite site as an alternate location for screening and outpatient assessments. The study will enroll 2 cohorts of 16 participants each, who will be randomised 3:1 to receive MAP 315 (4 x 10^7 CFU of MAP 315 per capsule) or its matching placebo for 14 consecutive days (2 weeks). The first Cohort will receive one capsule of MAP 315 (4 x 10^7 CFU of MAP 315 per capsule) or matching placebo daily administered orally for 14 consecutive days, (total daily dose of 4 x 10^7 CFU of MAP 315). Cohort 2 will receive four (4) MAP 315 capsules, twice daily for a total of 8 MAP 315 capsules per day for 14 consecutive days, (a total daily dose of 3.2 x 10^8 CFU of MAP 315). The capsules are administered orally with water and regardless of food. Participants in the study will be confined in the clinical research unit (CRU) from Day -1 until Day 3, when they will be discharged after completion of all CRU-based assessments scheduled for that day, in the absence of clinically significant signals, at the discretion of the Principal Investigator. Both dose level cohorts (Cohort 1 and Cohort 2) will include at least 2 sentinel participants: 1 to receive MAP 315 and 1 to receive placebo. If dosing of the sentinel participants proceeds without clinically significant safety signals up to at least 72 hours (h) following the administration of the initial study drug dose, as determined by the Principal Investigator in consultation with the local Medical Monitor and Sponsor if required), the remaining 14 participants in the cohort can be dosed according to the randomisation schedule. The decision to proceed to Cohort 2 of the study will be dependent upon review of data from all participants in Cohort 1 up to at least 6 days after the beginning of dosing (ie, the Day 7 visit) by a safety monitoring committee (SMC). This will include the review of all safety data and available PK data for at least 12 participants in Cohort 1.

Interventions

MAP 315 is being developed for administration for the treatment of ulcerative colitis. The active ingredient of MAP 315 is a live bacterium that is a common member of the gut microbiome of healthy adults. MAP 315 drug product consists of lyophilised MAP 315 with excipient(s) in an enteric-coated capsule for oral administration. The study will enroll 2 cohorts of 16 participants each, who will be randomised 3:1 to receive MAP 315 capsules (4 x 10^7 CFU of MAP 315 per capsule) or placebo capsule

The study will enroll 2 cohorts of 16 participants each, who will be randomised 3:1 to receive MAP 315 capsules (4 x 10^7 CFU of MAP 315 per capsule) or placebo capsules administered daily in the morning (before 12 noon) for 14 consecutive days. The capsules are administered orally with water and regardless of food. Cohort 1 will receive one capsule of MAP 315 or placebo administered daily in the morning (before 12 noon) for 14 consecutive days (total daily dose of 4 x 10^7 CFU of MAP 315). Cohort 2 will receive four (4) capsules of MAP 315 or placebo administered in the morning (before 12 noon) and 4 capsules administered in the evening (10 to 14 hours after the morning dose) for a total of 8 capsules a day daily for 14 consecutive days (a total daily dose of 3.2 x 10^8 CFU of MAP 315. Each Cohort will be administered to a distinct group of participants and escalation to Cohort 2 will occur only after completion of a review by the safety review committee of at least 6 days post-treatment clinical safety and tolerability findings and available pharmacokinetic data of at least 12 participants in Cohort 1. For both cohorts, the intervention will be administered for the first 3 days at the clinical trial unit (CRU) by trained clinical trial site staff and the following 11 days by self-administered by the participant outside of the CRU. A study diary will be utilised to monitor intervention adherence during the outpatient period (days 4 to 14). Diary entry review will be conducted by site staff at each participant interaction.

Inclusion criteria

1. Male or female participants aged between 18 to 65 years inclusive at Screening. 2. The participants must be in good general health, as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, vital signs, safety laboratory tests and cardiac monitoring at Screening, and/or before administration of the initial dose of the study drug (active or placebo). 3. The participants must weigh greater than or equal to 50 kg and have a body mass index (BMI) between 18 and 32 kg/m2 inclusive at Screening. 4. The participants must agree to abstain from alcohol intake and must agree to not consume poppy seeds from at least 48 hours before the initial administration of the study drug, during all the confinement period, and from at least 48 hours prior to any scheduled site visits. 5.
