Phase 1

Recruiting

• Conditions: Solid Tumor
• Interventions: Drug: Test Product HYP-6589

• Registration Number: NCT06712680
• Lead Sponsor: Sichuan Huiyu Pharmaceutical Co., Ltd

Brief Summary

This is a multi-center , open-label, phase 1/2 study to evaluate the safety, efficacy, and pharmacokinetic (PK) characteristics of HYP-6589 in monotherapy in advanced solid tumors and combination with tyrosine kinase inhibitors in patients with advanced NSCLC with target-driven gene positivity.

Detailed Description

The study starts with a dose escalation part (Part 1) followed by a dose expansion part (Part 2). The main purpose of this study is to evaluate the safety and tolerability of the drug HYP-6589 and determine the maximum tolerated dose (MTD) (if any) and/or the recommended dose(s) (RD) and preliminary anti-tumor activity. Additional purposes of the study are to evaluate the pharmacokinetics (PK) properties.

• Participants who have received (attenuated) live vaccines within 4 weeks prior to the first administration of the study drug;
• Participants who have undergone major organ surgery (excluding biopsy) within 4 weeks prior to the first administration of the study drug or have experienced significant trauma, or who require elective major organ surgery (excluding biopsy) during the study period;
• Participants who, based on computerized tomography (CT) or magnetic resonance imaging (MRI) examinations conducted during the screening period and before radiological assessment, have uncontrolled, unstable, or active central nervous system (CNS) metastases;
• Participants with clinically uncontrollable hypertension (defined in this protocol as having a systolic blood pressure > 150 mmHg and/or a diastolic blood pressure > 100 mmHg despite antihypertensive treatment, and which is considered clinically significant by the investigator);

• Participant whose toxicities from previous anti-cancer therapy have not resolved, defined as toxicity (hair loss excluded) that has not resolved to grade ≤1 (CTCAE 5.0 version, peripheral neuropathy, ≤grade 2; exclusion criteria specified);
• Female participants who are breastfeeding or have positive urine or blood pregnancy test results during the screening period; female participants who have a planned pregnancy, sperm donation, or egg donation during the study period or within 6 months after the last study drug administration;
• Known history of hypersensitivity to any of the components of the test formulation.
• Participants who have had other malignancies within the past 5 years, excluding cured cervical carcinoma in situ, basal cell carcinoma of the skin or squamous cell carcinoma of the skin;
