Plain-language summary
This clinical trial is looking at UCB4594. This is the first time the drug is being tested in humans. UCB4594 is a type of drug called a monoclonal antibody. It has been designed to work by targeting a protein called human leucocyte antigen G (HLA-G) that is found in high levels on some cancer cells. By attaching itself to this protein it may help the immune system to attack and kill the cancer cells.
The four main aims of the clinical trial are to find out:
1. The best dose of UCB4594 that can be given safely to participants in the trial.
2. What the side effects of UCB4594 are and how they can be managed.
3. What happens to UCB4594 inside the body and how it affects cancer cells.
4. Whether UCB4594 can cause cancer to shrink.

Inclusion criteria
✓. Written (signed and dated) informed consent and capable of co-operating with investigational medicinal product (IMP) administration and follow-up
✓. Participant population: Histologically or cytologically proven advanced solid tumours (as specified below), refractory to conventional treatment, or for which no conventional therapy is considered appropriate by the Investigator or is declined by the participant. Module A (dose escalation): Tumour types which have shown high levels of human HLA-G expression (as reported in the literature): head and neck squamous cell carcinoma, non-small cell lung cancer, colorectal cancer, triple-negative breast cancer, renal cell cancer (clear cell only), oesophago-gastric cancer (excluding gastrointestinal stromal tumour), cervical cancer, ovarian cancer, pancreatic cancer. N.B. Participants with small cell type cancers on histology/cytology are excluded. Pre-treatment biopsies are mandatory for all participants. Paired biopsies will be mandatory for participants from doses of 30 mg and higher. Participants must have disease amenable to biopsy (excluding bone metastases) as deemed safe by the Investigator
✓. Measurable disease, according to RECIST v1.1
✓. Life expectancy of at least 12 weeks
✓. Eastern Cooperative Oncology Group performance status of 0 or 1
✓. Haematological and biochemical indices within defined ranges. These measurements should be performed to confirm the patient's eligibility to participate in the trial
What they're measuring
1
Recommended Phase 2 dose (RP2D) of UCB4594
Timeframe: From Day 1 (date of first dose of UCB4594) up to Day 21.
2
Frequency of adverse events (AEs) considered at least possibly related to UCB4594 (up to 18 cycles).
Timeframe: From time of informed consent up to 12 months
✓. Aged 18 years or over at the time consent is given. Participants aged 16-17 years may be eligible for recruitment to the backfill cohorts in dose escalation once adequate safety and toxicity data have been established in participants aged 18 years or over. All relevant data will be reviewed and a decision on the inclusion of participants aged 16-17 years will be made by the Trial Management Group
Exclusion criteria
✕. Radiotherapy (except palliative), endocrine therapy (unless for non-malignant disease), chemotherapy, targeted therapy or immunotherapy, or any other IMPs during the previous 4 weeks or 5 half-lives (whichever is shorter) before the first dose of IMP
✕. Ongoing toxicity of previous treatments \>CTCAE Grade 1 (except alopecia of any grade, stable Grade 2 peripheral neuropathy or hormone-replacement therapy (HRT)-managed endocrine disorders)
✕. Patients with rapidly progressing / symptomatically deteriorating brain/leptomeningeal metastases/untreated brain metastases are excluded. Patients with previously treated brain metastases are eligible if they haven't had a seizure or a clinically significant change in neurological status or required steroids in the last 2 weeks
✕. Pregnant or breastfeeding female patients (or planning to breastfeed)
✕. Women of childbearing potential. However, those not already pregnant or breastfeeding (or who discontinue breastfeeding) and meet the following are eligible:
✕.1. Have a negative serum pregnancy test within 7 days before enrolment and either:
✕.2.1. Agree to a form of highly effective contraception plus a barrier method, or
