Brief summary

This is a modular, Phase I/II, multicentre study to investigate CT7001 monotherapy in advanced solid malignancies and to further investigate CT7001 as monotherapy or in combination with standard therapy in specific participant groups with Triple Negative Breast Cancer (TNBC), Castrate Resistant Prostate Cancer (CRPC) and in combination with fulvestrant for patients with hormone receptor-positive (HR+ve) / human epidermal growth factor-2 negative (HER2-ve) breast cancer.

Detailed description

Module 1 comprises two sequential parts: * Part A: First-in-human (FiH) dose escalation investigating the safety and tolerability of CT7001 to identify the minimum biologically active dose (MBAD) and maximum tolerated dose (MTD). Part A also includes a cohort expansion for breast cancer participants only: this includes sequential tumour biopsies for evaluation of pharmacokinetic (PK), pharmacodynamic (PD) and tumour responses. The module is completed. * Part B: To refine the safety, tolerability, and PK and PD profiles of CT7001 monotherapy in participants with advanced solid malignancies from up to four tumour- specific cohorts, which may include, but is not limited to, triple-negative breast cancer, ovarian cancer, small-cell lung cancer and prostate cancer. * Part B, Cohort 1, Triple-Negative Breast Cancer (M1B-1 TNBC) treated with CT7001 as monotherapy. The module is completed. * Part B, Cohort 2, Prostate Cancer (M1B-2 CRPC) treated with CT7001 as monotherapy. The module is completed. * Module 2 is a Phase Ib/II, 3-part safety and efficacy study in participants with hormone- receptor positive (HR+ve) and human epidermal growth factor-2 negative (HER2-ve) breast cancer. This module includes dosing CT7001 in combination with fulvestrant. Module 2 was planned to comprise of 3 parts; Part A (open-label, single-arm, ascending dose study), Part B (double blinded, randomised, placebo-controlled study) and Part C (crossover from Part B). However, only Module 2 Part A was initiated and completed. Therefore, further sections of this record only reflect Module 2 Part A information. * Module 4 is a study investigating the effect of food on the PK of CT7001 monotherapy in participants with advanced solid malignancies. The module is completed. * Module 6 was planned as a Phase 1 study to explore the tolerability of, and the total and peak exposure of, an enteric capsule formulation of CT7001 \[CT7001(EC)\], when given as monotherapy to patients with advanced solid malignancies. Module 6 was not initiated.

Exclusion criteria

1. Any other malignancy that has been active or treated within the past 3 years, with the exception of cervical intraepithelial neoplasia and non-melanoma skin cancer 2. Any unresolved toxicity (except alopecia) from prior therapy of ≥ CTCAE Grade 2 3. Spinal cord compression or brain metastases, unless asymptomatic, stable, and not requiring steroids for at least 4 weeks before the first dose of investigational product (IP) 4. Refractory nausea and vomiting, chronic gastrointestinal (GI) disease or previous significant bowel resection, with clinically significant sequelae that would preclude adequate absorption of CT7001 5. Uncontrolled seizures 6. Active infection requiring systemic antibiotic, antifungal, or antiviral medication 7. Severe or uncontrolled medical condition or psychiatric condition 8. Active bleeding diatheses 9. Renal transplant 10. Known hepatitis B, hepatitis C, or human immunodeficiency virus infection 11. Breastfeeding or pregnancy 12. Receipt of systemic cytotoxic treatment for the malignancy within 28 days or ≤ 5 half-lives, whichever is shorter before the first dose of IP 13. Receipt of non-cytotoxic treatment for the malignancy within 5 half-lives of the drug before the first dose of IP 14. Receipt of corticosteroids (at a dose \> 10 mg prednisone/day or equivalent) within 14 days before the first dose of IP 15. Receipt of any small-molecule investigational medicinal product (IMP) within 28 days or ≤ 5 half-lives, whichever is shorter before the first dose of IP 16. Receipt of any biological IMP (e.g., immune checkpoint blockers, antibodies, nanoparticles) within 42 days before the first dose of IP 17.
