Study to Assess Safety, Tolerability and Efficacy of Incremental Doses of MGB-BP-3 in Patients With CDAD

Phase 2
Completed
Conditions
Clostridium Difficile Infection
Interventions
Registration Number
NCT03824795
Lead Sponsor
MGB Biopharma Limited
Brief Summary

The objective of this Phase IIa study is to assess the safety, tolerability, and efficacy of incremental doses of MGB-BP-3 in patients with Clostridium difficile-associated diarrhea (CDAD).

Detailed Description

This is an exploratory, Phase IIa, open-label study assessing the safety, tolerability, and efficacy of incremental doses of MGB-BP-3 with 3 sequential groups of 10 patients with CDAD. Patients will be administered an oral dose of MGB-BP-3 for 10 days (Day 1 to Day 10). At the end of the treatment period, patients will be followed for up to 8 weeks to assess the incidence of disease recurrence.

Primary Outcome Measures
NameTimeMethod
Initial cure rate at 12 days post initiation of therapy.12 days

Initial clinical cure is defined as resolution of diarrhea (\<3 bowel movements with unformed stools within 24 hours \[Type 5, 6, or 7 bowel movement on the Bristol Stool Chart\] for patients for 2 consecutive days), maintained for the subsequent duration of therapy (1 day of exacerbation and then return to the resolved state is acceptable), with no further requirement for CDAD therapy, assessed by EOT and sustained for 2 days after the end of the 10-day initial treatment course.

Number of participants with treatment-related adverse events assessed by the Investigator, as per CTCAE v.5.0.40 days

Incidence of treatment emergent adverse events (Safety and Tolerability of up to 3 incremental doses of MGB-BP-3 in patients with CDAD).

Secondary Outcome Measures
NameTimeMethod
Time to peak plasma concentration (Tmax).10 days

Days 1, 5 and 10.

CDAD RecurrenceUp to 8 weeks

Recurrence of CDAD within 4 weeks (8 weeks optional) post end of treatment.

Peak plasma concentration (Cmax).10 days

Days 1, 5 and 10.
