Primary outcomePrimary: Serious Adverse Events (SAEs) and Non-serious Adverse Events (AEs) Considered to be at Least Possibly Related to MOv18 IgE — 0; 5; 2; 0 Participants
Summary
This first in human study of the new therapeutic antibody MOv18 immunoglobulin (Ig) E, which targets a protein called folate receptor alpha (FRa), in patients with advanced cancer seeks to demonstrate the potential for the use of this IgE antibody as an example of the use of the IgE class of antibodies for the treatment of cancer.

Eligibility Criteria
Inclusion Criteria
- Histologically or cytologically-proven advanced, unresectable solid tumour of a type known to express FRα in a percentage of cases
- Archival tumour tissue expressing FRα (1+, 2+ or 3+ membrane staining on at least 5% of tumour cells by immunohistochemistry using the BN3.2 antibody, based on the technique described by Lawson & Scorer, 2010).
- Advanced disease for which no alternative therapy is felt to be appropriate.
- Measurable disease or disease evaluable by tumour marker. Measurable disease is preferred for patients entering higher cohorts to facilitate efficacy assessments.
- World Health Organisation (WHO) performance status of 0 or 1 and a life expectancy of at least 12 weeks.
- Haematological and biochemical indices within the ranges shown below. These measurements should be performed within 7 days before the first dose of MOv18 IgE (Day -7 to Pre-dose on Day 1). Measurements performed before Day -7 may be accepted by the CDD to demonstrate eligibility if repeat testing is logistically difficult for the patient and is not considered necessary medically in the opinion of the Investigator or CDD.
Laboratory Test Value required Haemoglobin (Hb) ≥ 9.0 g/dL Absolute neutrophil count ≥ 1.5 x 10^9/L Platelet count ≥ 100 x 10^9/L Serum bilirubin ≤ 1.5 x upper limit of normal (ULN) Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x ULN unless raised due to liver metastases in which case up to 5 x ULN is permissible Serum creatinine ≤ 1.5 x ULN
- Aged 16 years or over at the time consent is given.
- Written (signed and dated) informed consent and capable of co-operating with treatment and follow-up.
Exclusion Criteria
- Radiotherapy (except for palliative reasons), endocrine therapy, immunotherapy or chemotherapy during the previous four weeks (six weeks for nitrosoureas and mitomycin-C) and investigational medicinal products during the previous 4 weeks, or 5 product half-lives before treatment.
- Patients on beta-blockers and unable to interrupt beta-blockade (which may counteract the therapeutic effects of adrenaline), or tricyclic anti-depressants/MAOIs (which can dangerously augment the effects of adrenaline). These agents should be discontinued at least 4 half-lives before administration of the first dose of MOv18 IgE and for the duration of MOv18 IgE therapy.
- Patients on bisphosphonates or treated with bisphosphonates in the last 18 months.
- Ongoing toxic manifestations of previous treatments that have not resolved to Grade 1 or lower (other than alopecia of any grade or Grade 2 peripheral neuropathy).
- Known brain metastases that have not been previously treated and been stable for at least 2 months.
- Female patients who are able to become pregnant (or already pregnant or lactating). However, those female patients who have a negative serum or urine pregnancy test before enrolment and agree to use two highly effective forms of contraception (oral, injected or implanted hormonal contraception and condom; have an intra-uterine device and condom; diaphragm with spermicidal gel and condom) effective at the first administration of IMP, throughout the study and for six months afterwards are considered eligible.
- Male patients with partners of child-bearing potential (unless they agree to take measures not to father children by using one form of highly effective contraception at the first administration of IMP, throughout the study and for six months afterwards) or agree to sexual abstinence*. Men with pregnant or lactating partners should be advised to use barrier method contraception (for example, condom plus spermicidal gel) to prevent exposure to the foetus or neonate.
- Abstinence is only considered to be an acceptable method of contraception when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of con
