MRx0518 in Patients With Solid Tumours Waiting Surgical Removal of the Tumour

A First in Human, Phase 1 Safety Study in Two Parts to Determine the Safety, Tolerability and Anti-cancer Immune-modulatory Effects of MRx0518 in Patients With Solid Tumour Awaiting Surgical Removal of the Tumour.

• Status: Unknown
• Phase: Phase 1
• Study type: Interventional

Summary

The primary objective is to determine the safety and tolerability of the novel compound, MRx0518 in patients with solid tumours at 30 days post-surgery. 20 participants will receive open label MRx0518 in a preliminary safety phase. After successful evaluation by the Independent Safety Monitoring Committee (IDMC), a further 100 participants will be recruited to receive MRx0518/Placebo.

Detailed description

This is a first in human, single centre study in two parts, which aims to determine the safety and tolerability of the novel biotherapeutic compound, MRx0518, to examine its use as an anti-cancer and immune system modulating agent in patients with a range of solid tumours, over 2 years. MRx0518 is composed of a proprietary strain of bacterium (Enterococcus species) which is found in the gastrointestinal tract of approx. 25% of humans and is predicted, from preclinical studies, to produce beneficial effects in humans. Patients who have been diagnosed with melanoma, breast, ovarian, uterine, prostate, urethra, bladder, renal, lung or head and neck cancer, who are amenable to surgical resection, will receive MRx0518 (part A) or MRx0518/placebo (part B) orally twice daily for 2-4 weeks until surgery to remove the tumour. In part A, 20 patients will receive open label MRx0518 as part of a preliminary safety assessment. Following surgery, patients will attend a 30 day, 6 month, 12 month and 24 month follow up visit. Following successful evaluation of part A data by the Independent Data Monitoring Committee (IDMC) the study will continue to recruit a further 100 patients to Part B of the trial. Part B will be placebo controlled, in which patients will be randomised in a double blinded fashion in a 4:1 ratio of MRx0518:placebo. In total, 120 patients will be recruited into the study (20 from part A and 100 from part B).

Interventions

Type	Name	Description
DRUG	MRx0518 Capsules	MRx0518 is a live biotherapeutic product consisting of a lyophilised formulation of a proprietary strain of bacterium. The dosing regimen is one capsule orally twice daily for 2-4 weeks until surgery.
DRUG	MRx0518/placebo Capsules	MRx0518/placebo product consist of a lyophilised formulation of either a proprietary strain of bacterium or placebo.The dosing regimen is one capsule orally twice daily for 2-4 weeks until surgery. Placebo capsules are manufactured to mimic MRx0518 capsules and contain the same excipients as the active biotherapeutic product.
