Inclusion criteria
. Written (signed and dated) informed consent and capable of co-operating with investigational medicinal product administration and follow-up.
. Phase 1, dose escalation phase
. MSS CRC with PIK3CA or HER2 mutation, and/or other driver mutation as agreed with the Sponsor (genomic alteration to have been previously identified using a validated next-generation sequencing method performed on either tumour tissue or circulating tumour DNA \[ctDNA\]);
. Gastric or gastroesophageal junction (GOJ) adenocarcinoma;
. Clear cell renal cell carcinoma;
. mCRPC
. Patients with mCRPC: biopsies are not required for those whose only safely accessible lesions are bone metastases that lack an accessible soft tissue component.
. For the first 12 participants in each indication: the on-trial biopsy is optional; and the baseline biopsy is mandatory if there is a safely accessible lesion but may be omitted for patients who have no safely accessible lesion, to permit their inclusion in the study. This will continually be assessed through the study.
Exclusion criteria
. Radiotherapy (except for palliative reasons), chemotherapy, non chemotherapy systemic anti-cancer therapy (apart from life-long hormone suppression such as luteinising hormone-releasing agents in participants with mCRPC) or investigational medicinal products during the 4 weeks prior to enrolment; or first dose of an immunotherapy during the previous 12 weeks before first dose of HTL0039732.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Maximum tolerated dose (MTD; Dose Escalation Phase)
Timeframe: From first dose of HTL0039732 up to the end of Cycle 1, a time frame of up to 30 days.
2
RP2D (Dose Escalation Phase)
Timeframe: From first dose of HTL0039732 up to the off-study visit (maximum 115 weeks).
3
Number of Adverse Events (AEs) Related to HTL0039732 (Dose Escalation and Expansion Phase)
Timeframe: Safety data will be collected from the time of informed consent until 28 days after the last dose of HTL0039732. The average time from consent to the end of follow-up will be presented.
4
Number of AEs Related to Atezolizumab (Dose Escalation and Expansion Phase)
Timeframe: Safety data will be collected from the time of informed consent until 90 days after the last dose of atezolizumab. The average time from consent to the end of follow-up will be presented.
. Ongoing toxic manifestations of previous treatments that are Grade \>1 per CTCAE v5.0.
. Any central nervous system metastases (unless potential participants have had local therapy and are asymptomatic, radiologically stable and have been off steroids for ≥4 weeks prior to enrolment).
. Women of child-bearing potential (or who are already pregnant or lactating). Exceptions apply.
. Men with partners of childbearing potential. Exceptions apply.
. Major thoracic or abdominal surgery from which the potential participant has not yet recovered.
. At high medical risk because of non-malignant systemic disease, including active uncontrolled infection.
. Known history of current or latent tuberculosis, HIV or Hepatitis B or C infection.
