Brief 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).

Arm Intervention/treatment
Experimental: Part A

Open label, preliminary phase

20 participants

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.

Experimental: Part B

Randomised, double blinded phase

100 participants

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.




Primary Outcome Measures :
  1. Safety and tolerability of MRx0518 as determined through the collection of the number and severity of adverse vents (AEs) and serious adverse events (SAEs). [ Time Frame: Baseline upto 30 days post surgery. ]
    AEs and SAEs will be assessed by CTCAE v5.0

  2. Safety and tolerability of MRx0518 determined by clinically significant changes in biochemistry, haematology and urinalysis laboratory results. [ Time Frame: Baseline upto 30 days post surgery. ]
    Assessed by clinically significant changes in biochemistry results (albumin, bilirubin, urea, creatinine, total protein, c reactive protein, calcium, chloride, sodium, phosphorus, potassium, bicarbonate, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl-transferase, globulin, lactate dehydrogenase, creatine kinase, cholesterol, triglycerides, uric acid, and fasting glucose); haematology results (haemoglobin, platelets, RBC, haematocrit, WBC, neutrophils, lymphocytes, monocytes, eosinophils, basophils) and urinalysis results (occult blood, glucose, protein, ketones, nitrite, leucocytes, pH and specific gravity).

  3. Safety and tolerability of MRx0518 determined by clinically significant changes in vital signs. [ Time Frame: Baseline upto 30 days post surgery. ]
    Assessed by the measurement of pulse, blood pressure, temperature and respiratory rate.

  4. Safety and tolerability of MRx0518 as determined by clinically significant changes in electrocardiogram (ECG) results. [ Time Frame: Baseline upto 30 days years post surgery. ]
    Assessed by the measurement of RR interval, PR interval, QRS duration, QT interval and QTc interval.

  5. Safety and tolerability of MRx0518 as determined by clinically significant changes upon physical examination. [ Time Frame: Baseline upto 30 days post surgery. ]
    Assessed by clinically significant abnormal changes to the general appearance, skin, head and neck, lymph nodes, thyroid, musculoskeletal/extremities, cardiovascular, respiratory, abdomen and neurological assessment.


Secondary Outcome Measures :
  1. Response of MRx0518 determined by the measurement of tumour markers. [ Time Frame: Baseline (optional) and during surgery. ]
    Tissue biopsies taken at screening (optional) and during surgery and analysed for tumour biomarkers (e.g. Ca125 in gynaecological malignancies, Ca153 in breast cancer).

  2. Overall survival of patients who receive MRx0518 compared to placebo. [ Time Frame: Survival of subjects will be recorded up to 2 years post-surgery ]
    Survival of individual patients will be assessed from the start of treatment until death due to any cause.

  3. Have radiologically, histologically or cytologically confirmed melanoma, breast, ovarian, uterine, prostate, urethra, bladder, renal, lung, or head and neck cancer* that is considered amenable to primary surgical resection and where primary surgery is planned but would not routinely have been performed until 2-4 weeks post initial biopsy.*New primary cancers or recurrences are permissible provided the patient has not received chemotherapy, radiotherapy or surgery for the last two years prior to screening.

  7. Women of child-bearing potential and men must agree to use adequate and highly effective contraception for at least 28 days prior to dosing until one complete menstrual cycle post dosing for women and 3 months after the last dose for men. Alternatively, true abstinence may be used, where this is in line with the preferred and usual lifestyle of the patient.
  8. Able to swallow and retain oral medication.

Exclusion Criteria:

  1. Patients who have had any anti-cancer therapy within the last 2 years.
  2. Patients with cancer affecting the gastrointestinal tract or those where bowel resection is considered to be highly likely to be required.
  3. Patients may not be receiving any other investigational agents or receiving concurrent anti-cancer therapy. In addition, all herbal (alternative) medicines are excluded.
  4. Patients not willing, or for whom it is not planned, to undergo primary surgery for their cancer 2-4 weeks after initiation of therapy with IMP.
  5. Patient who would otherwise have undergone primary surgery within 2 weeks of starting therapy with IMP.
  6. Patients who have rapidly progressive local disease, or local disease that, in the opinion of the investigator, is not amenable to surgical resection.
  7. Patients with known structural or valvular heart valve defects, gastrointestinal fistula, feeding tubes and inflammatory bowel disease or those who are immunosuppressed or receiving immunosuppressant medication (steroids up to an equivalent dose of 20mg of prednisolone daily is allowed as long as the dose has been stable for the last 6 months).
  8. Patients who smoke or use nicotine in any form including e-cigarettes and nicotine patches or sprays or have smoked/used nicotine in the 3 months prior to screening.
  9. Patients who consume more than 14 units of alcohol per week, on a regular basis.
  10. History of allergic reactions attributed to compounds of similar biologic composition to MRx0518.
  11. Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, including patients with active hepatitis B virus (HBV), active hepatitis C virus (HCV) who have a detectable viral load, and patients with Human Immunodeficiency Virus (HIV), symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations, gastrointestinal disease that would limit compliance with study requirements.
  12. Any significant infection e.g. influenza, fever over 38°C, meningitis or an infection resulting in the subject seeking a consultation with a healthcare professional, within four weeks of starting IMP therapy.
  13. Pregnant women are excluded from this study because teratogenic or abortifacient effects are unknown. Furthermore, there is an unknown but potential risk for adverse events in nursing infants, secondary to treatment of the mother with MRx0518 so breastfeeding should be discontinued if the mother is treated with MRx0518.
