Modular Study to Evaluate CT7001 Alone in Cancer Patients With Advanced Malignancies
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.

- Receipt of non-cytotoxic treatment for the malignancy within 5 half-lives of the drug before the first dose of IP
- Receipt of corticosteroids (at a dose > 10 mg prednisone/day or equivalent) within 14 days before the first dose of IP
- 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
- Receipt of any biological IMP (e.g., immune checkpoint blockers, antibodies, nanoparticles) within 42 days before the first dose of IP
- Receipt of St John's Wort within 21 days before the first dose of IP or of another concomitant medication, herbal supplement, or food that is a strong inhibitor or inducer of CYP3A4, CYP2C19, CYP2D6, or P-glycoprotein (PGP) activity within 14 days before the first dose of CT7001
- Receipt of a blood transfusion (blood or blood products) within 14 days before the first dose of IP
- Known hypersensitivity to CT7001 or any excipient of the product
- Impaired hepatic or renal function as demonstrated by any of the following laboratory values:
- Albumin < 30 g/L
- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 2.5 × the upper limit of normal (ULN)
- > 5.0 × ULN for patients with liver metastases
- Total bilirubin > 1.5 × ULN
- Serum creatinine > 1.5 × ULN
- Liver function deteriorating in a manner that would likely make the participant meet the AST, ALT, or bilirubin levels specified above at the time of the first dose of IP
- Other evidence of impaired hepatic synthesis function
- Inadequate bone marrow reserve or organ function as demonstrated by any of the following laboratory values:
- Absolute neutrophil count (ANC) < 1.5 × 10^9/L
- Platelet count < 100 × 10^9/L
- Haemoglobin < 90 g/L
- Persistent (> 4 weeks) severe pancytopenia due to previous therapy rather than to disease (ANC < 0.5 × 10^9/L or platelets < 50 x 10^9/L)
- Cardiac dysfunction (defined as myocardial infarction within 6 months of study entry, New York Heart Association Class II/III/IV heart failure, unstable angina, unstable cardiac arrhythmias, or left ventricular ejection fraction < 55 percent)
- Mean resting QT interval corrected for heart rate by the Fridericia formula (QTcF) > 470 msec obtained from 3 electrocardiograms (ECGs) obtained within 5 minutes of each other prior to the first dose
- Any clinically important abnormalities in rhythm, conduction, or morphology on resting ECG (e.g., complete left bundle branch block, third degree heart block). Controlled atrial fibrillation (AF) is permitted
- Any factor that increases the risk of QTc prolongation or of arrhythmic events (e.g., heart failure, hypokalaemia, congenital long QT syndrome, immediate family history of long QT syndrome or unexplained sudden death under 40 years of age)
- In the opinion of the Investigator, unlikely to comply with study procedures, restrictions, or requirements
- A history of haemolytic anaemia or marrow aplasia
- Has received a live-virus vaccination within 28 days or less of planned treatment start Additional Module 1A

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.
