Brief Summary
This is a phase I/II, open-label, multi-center, first-in-human study designed to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity of SY-5007 administered or...
Detailed Description
The study consists of 2 parts: Part 1: Dose-escalation and dose-expansion in patients with RET Fusion-Positive NSCLC or RET-mutated MTC or other RET-altered advanced solid tumor. Dose-escalation stud...
Eligibility Criteria
Inclusion
- \-
- For Phase I:
- Male or female, at least 18 years of age.
- Eastern Cooperative Oncology Group (ECOG) performance status score of 0 to 1.
- Estimated life expectancy \>12 weeks.
- Patients must have at least one assessable lesion in dose-escalation part and one measurable lesion in dose-expansion part per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
- Dose-escalation Part: patients must have histological or cytological confirmed advanced solid tumours with RET alteration (fusion or mutation) and have progressed after standard therapy, or no standard or available curative therapy exists.
- Dose-expansion Part: Patients with advanced tumor must have histological or cytological confirmed RET alteration, including NSCLC patients with RET-fusion or MTC patients with RET-mutation or other patients with RET alteration, and either have progressed after standard therapy or no standard/ available curative therapy exists.
- Patients must have adequate organ function as defined in the below:
- Hepatic function:
- Serum aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≤ 3 times the upper limit of normal (ULN) if no hepatic metastases are present, or otherwise ≤ 5 times ULN, Total serum bilirubin (TBIL) ≤ 1.5 times ULN.
- Bone marrow function (No blood transfusion or haematopoietic stimulating factor treatment within 10 days prior to testing):
- Absolute neutrophil count (ANC) ≥ 1.5 x 10⁹/L; Platelets (PLT) count ≥ 75 x 10⁹/L; Hemoglobin (Hb) ≥ 85 g/L.
- Renal function:
- Creatinine clearance ≥ 50 mL/min.
- Coagulation function:
- Prothrombin time (PT) or International Normalized Ratio (INR) ≤ 1.5 times ULN.
- Serum lipid:
- Cholesterol ≤ 500mg/dL（12.92mmol/L）.
- Female patients with reproductive potential must have a negative serum pregnancy test within 7 days prior to the first dose, male and female patients of childbearing potential must be willing to completely abstain or agree to use an appropriate method of contraception during the entire study duration and for at least 3 months after the last dose of study medication.
- Willingness and ability to give informed consent and follow protocol procedures, and comply with follow-up visit requirements.
- For Phase II: As for phase I with the following modifications:
- Participants must have histological or cytological confirmed locally advanced or metastatic RET Fusion-Positive NSCLC, have progressed following platinum-based chemotherapy and/or PD-1/PD-L1 immunotherapy, or have not received prior systemic therapy, or in the opinion of the Investigator, they would be unlikely to tolerate or derive significant clinical benefit from appropriate standard of care therapy, or they declined standard therapy.
- The participants' tumor tissue or blood sample test results meet 1 of the following 2 criteria:
- Previous tumor tissue or blood sample confirmed positive for RET fusion by local laboratory.
- If no previous positive RET fusion test report is available, a compliant tumor tissue or blood sample must be tested at a central laboratory designated by the sponsor, using a second-generation sequencing (NGS)-based assay, and confirmed as positive for RET fusion.
Exclusion
- Dose-expansion Part: Patient's cancer has a known primary driver alteration other than RET. e.g. EGFR, ALK, ROS1, KRAS, etc.
- Dose-expansion Part: Patients previously treated with a selective RET inhibitor.
- Patients received systemic antitumor therapy, including chemotherapy, radiotherapy, biologic therapy, endocrine therapy, or immunotherapy within 3 weeks prior to the first dose, except for the following:
- Nitrosoureas or mitomycin C within 6 weeks; Oral fluorouracils and small molecule drugs within 2 weeks or within 5 half-life periods of the drug (whichever is longer); Antitumour traditional Chinese medicine within 2 weeks.
- Patients received other unlisted clinical trial drugs or treatments within 4 weeks prior to the first dose.
- Patients underwent major organ surgery (excluding puncture biopsy) or had significant trauma within 4 weeks prior to the first dose.
- Adverse effects of previous anti-tumor therapy have not recovered to CTCAE 5.0 grade rating of ≤ grade 1 (except for toxicity judged by the investigator be of no safety risk, such as alopecia, grade 2 peripheral neurotoxicity, etc.)
- Patients have symptomatic central nervous system (CNS) metastases, meningeal metastases, or a primary CNS tumor that is associated with progressive neurological symptoms.
- Patients with active uncontrolled systemic bacterial, viral, or fungal infection despite optimal treatment (chronic disease screening not required).
- Active hepatitis (Hepatitis B: HBsAg-positive and HBV-DNA ≥ 2000 IU/ mL; Hepatitis B: HCV antibody-positive and HCV-RNA ≥ 1000 IU/ml), HIV antibody-positive; Active syphilis.
- Patients have a history of severe cardiovascular disease, including but not limited to:
- Severe cardiac rhythm or conduction abnormalities, e.g. ventricular arrhythmia requiring clinical intervention, II-III degree atrioventricular block, etc.
- Mean QT interval corrected using Fridericia's formula (QTcF)\> 480ms at rest. Acute coronary syndrome, congestive heart failure, aortic coarctation, stroke or other grade 3 or higher cardiovascular or cerebrovascular events within 6 months prior to the first dose.
- New York Heart Association (NYHA) ≥ class II heart failure or left ventricular ejection fraction (LVEF) \< 50%.
- Hypertension remains uncontrolled after aggressive antihypertensive therapy.
- Patients have been treated with any CYP3A inhibitors or inducers within 14 days prior to the first dose.
- Patients with malignancies other than tumors treated in this study (except: malignancies that are cured and have not recurred within 3 years prior to study entry; completely resected basal cell and squamous cell skin cancer; completely resected carcinoma in situ of any type).
- Patients are unable to swallow the drug orally, or has a condition that seriously affects gastrointestinal absorption in the judgment of the investigator.
- For Phase II: As for phase I with the following modifications:
- Patients received any selective RET inhibitor (including marketed drugs such as selpercatinib, pralsetinib, and unmarketed experimental drugs).
- Patients have a history of hypersensitivity to any component or excipient of SY-5007 capsule.
- Patients participated in another clinical study within 4 weeks prior to the first dose or is scheduled to participate in another clinical study during the study period.
- Pregnant or breastfeeding female patients.
- Other conditions deemed by the investigator to be inappropriate for participation in this clinical trial.
