NCT07251166 | Recruiting Phase 1

• 1 other identifier: GenSci140-101
• Study Type: interventional
• Target: 170
• Locations: 1 country
• Sites: 1

Brief Summary

This is a phase I, multi-center, open-label, dose-escalation (Part 1) and dose-expansion (Part 2) first-in-human study in China to evaluate the safety, tolerability, PK profile and efficacy of GenSci140 in participants with advanced solid tumors, and to determine the MTD (if any) and RDE. The dose-expansion study aims to evaluate the efficacy, safety and PK profile of GenSci140 in the treatment of ovarian cancer or other FRα-positive advanced solid tumors at different dose levels, and to select an appropriate RP2D (if applicable).

Conditions

  up to 5 months

• disease control rate（DCR）

  To evaluate the preliminary efficacy of GenSci140 in participants with advanced solid tumors

  up to 5 months

• Incidence and severity of adverse event (AEs)

  To evaluate the safety and tolerability of GenSci140 at specific doses in participants with specific advanced solid tumors.

  up to 5 months

Study Arms (2)

Dose Level 1~ Dose Level 5

EXPERIMENTAL

Participants who meet the inclusion criteria and do not meet the exclusion criteria will be sequentially enrolled into five pre-specified doses for dose groups 1-5.

Drug: GenSci140 for Injection

Cohort 1~ Cohort 4

EXPERIMENTAL

Cohort 1: Cohort 1 is planned to be conducted in patients with ovarian cancer. Cohort 2: FRα-positive endometrial cancer. Cohort 3: FRα-positive lung cancer. Cohort 4: FRα-positive triple negative breast cancer.

Drug: GenSci140 for Injection

Interventions

GenSci140 for Injection DRUG

Participants will receive GenSci140 on Day 1 of each 21-day cycle. GenSci140 will be administered until unacceptable toxicity, disease progression, withdrawal of informed consent, death, loss to follow-up, or initiation of new anti-tumor therapy (whichever occurs first).

Cohort 1~ Cohort 4; Dose Level 1~ Dose Level 5

Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Those who are able to understand and willing to sign written Informed Consent Form.
• Aged between 18 and 75 years (inclusive) when signing the ICF
• Participants with advanced solid tumors
• The participant agrees to provide fresh biopsy or archived tumor tissues for testing by the central laboratory.
• At least one evaluable lesion in the dose-escalation part, and at least one measurable lesion in the dose-expansion part.
• Eastern Cooperative Oncology Group performance status (ECOG PS) 0 or 1.
• Life expectancy ≥ 3 months.
• Adequate hematologic and organ function before the first dose of GenSci140.
• All toxicities related to prior anti-tumor therapies must have resolved to Grade ≤ 1, with the following exceptions: alopecia, peripheral neurotoxicity (must have resolved to Grade ≤ 2).
• For participants with congestive heart failure (CHF), it must be Grade ≤ 1 in severity and must have recovered completely prior to enrollment.
• Normal QT interval on electrocardiogram (ECG) evaluation at screening
• Participants who test negative for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV).
• Women of childbearing potential (WOCBP) must have a negative serum pregnancy test result. WOCBP must agree to avoid pregnancy.
• Men with female partners of childbearing potential must take appropriate precautions to avoid pregnancy of partner and use appropriate barrier contraceptives or abstinence

You may not qualify if:

• Past history of cancers.
• Symptomatic primary central nervous system (CNS) tumors, metastases, leptomeningeal carcinomatosis, or therapy naive spinal cord compression.
• Use of an investigational medicinal product (IMP) or antitumor therapy (including chemotherapy, biologic therapy, immunotherapy) within 5 half-lives or 4 weeks before the first dose of GenSci140. Concomitant anti-tumor therapy is not permitted
• Major surgery within 4 weeks prior to the first dose of GenSci140.
• Radiotherapy for ≥ 20% of bone marrow or large area of radiotherapy within 4 weeks prior to the first dose of GenSci140. Or participants have not recovered from acute effects of radiotherapy to baseline prior to the first dose of GenSci140.
• Clinically significant active cardiovascular disorder or history of myocardial infarction within 6 months prior to the first dose of GenSci140.
• Uncontrolled active systemic bacterial, viral, or fungal infection or ongoing serious systemic disease, such as hypertension or diabetes, despite Best Supportive Care. Chronic disease screening is not required.
• History of multiple sclerosis or other demyelinating diseases, Eaton-Lambert syndrome (paraneoplastic syndrome), alcoholic liver disease, history of internal haemorrhage or ischemic stroke within the past 6 months, haemorrhagic diathesis that are unsuitable for enrollment as assessed by the investigator.
• Suspected treatment-related pneumonitis that was clinically diagnosed in the past and currently requires steroids or cannot be ruled out by imaging at screening.
• Uncontrolled pleural effusion, pericardial effusion, or abdominal and pelvic fluid collection requiring drainage and/or diuretics within 14 days prior to the first dose of GenSci140.
• Pregnant or lactating women.
• Known hypersensitivity to prior monoclonal antibody therapy.
• Patients who previously underwent allogeneic or autologous bone marrow transplantation.
• Participants whom the investigator deems unsuitable for enrollment in this clinical study
