Официальное название

A Phase 1, Multicenter, Single Agent Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Evidence of Antitumor Activity of CPO301, an EGFR-Targeting Antibody-Drug Conjugate, in Adult Patients With Advanced or Metastatic Solid Tumors

Обзор

The goal of this clinical trial is to test CPO301, a type of drug called an antibody drug conjugate in adult patients with advanced or metastatic solid tumors. The main questions it aims to answer are: * To assess the safety and tolerability of CPO301 at increasing doses and determine the dose to be used in the second part of the study (Part A) * To assess the safety and tolerability of CPO301 at the dose determined to be safe and tolerable in Part A in patients with Non-Small Cell Lung Cancer and potentially other tumor types (Part B) * To evaluate how quickly CPO301 is metabolized by the body (pharmacokinetics or PK) * To evaluate if antibodies to the study drug develop (immunogenicity) * To evaluate preliminary efficacy to the drug * To correlate preliminary efficacy with mutations in a biomarker called EGFR Participants will: * Provide written informed consent * Undergo screening tests to ensure they are eligible for study treatment * Attend all required study visits and receive CPO301 by intravenous injection every 3 weeks until the study doctor determines study treatment should be stopped, based on how well a participant is doing on treatment * Be followed for progression every 3 months for up to 2 years

Подробное описание

This Phase 1 study is a multicenter, dose-escalating, dose-expansion, single agent, 2-part study conducted in patients with advanced or metastatic solid tumors who progressed on ≥1 prior conventional systemic therapy or who were ineligible or intolerant to standard treatment or had no or refused standard treatment.

Dose escalation (Part A) - Dose escalation will be guided by a modified 3+3 design to determine the maximum tolerated dose (MTD) or recommended dose of CPO301 (also known as SYS6010). Determination of dose-limiting toxicity (DLT) will be based on toxicity observed during the DLT observation period (first 21 days \[1 cycle\]). Dose escalation decisions are made based on the occurrence of DLT. MTD will be determined based on the data of all enrolled participants. To better identify the MTD, one or more dose groups may also be added beyond the planned maximum dose group (if determined to be safe), or between the maximum escalation dose group and the next lower dose group for DLT assessment. Intermediate dose groups and/or adjustment to the dosing frequency may be made

Dose expansion (Part B) - Additional patients will be enrolled at the recommended dose determined in the dose escalation stage. An additional tumor cohort may be added based on data observed in Part A.

Критерии участия

Major Inclusion Criteria:

Age ≥18 years
Patients with histologically confirmed locally advanced or metastatic solid tumors who have disease progression, intolerance to prior therapy, are ineligible for available therapies, or refuse standard of care therapy in the metastatic setting.

Life expectancy >12 weeks

Major Exclusion Criteria:

Known, active, or uncontrolled central nervous system (CNS) metastasis or carcinomatous meningitis.

Any serious and/or uncontrolled concurrent illness that may interfere with study participation

Prior therapy
