Brief Summary

This is a multi-center, open-label, Phase I/II clinical study of MCLA-129 as monotherapy in patients with advanced solid tumors to evaluate the safety, pharmacokinetic characteristics and antitumor activity of MCLA-129.

Detailed Description

This is a multicenter, open-label, single-agent phase I/II clinical study of MCLA-129 in patients with advanced solid tumors to evaluate the safety, pharmacokinetic profile, and antitumor activity of MCLA-129. The study consists of two parts: Part I is a phase I dose- finding study in patients with advanced solid tumors, including a dose escalation phase and a dose expansion phase; Part II is a phase II parallel cohort expansion study to further evaluate the efficacy, safety and PK profile of MCLA-129 in sub-cohorts of patients with advanced non-small cell lung cancer and other solid tumors.

• For Part 2, patients shall meet the inclusion criteria for each cohort by biomarker testing.

Cohort A: Patients with advanced NSCLC who are previously diagnosed with EGFR mutations and treated with third-generation EGFR-TKIs for drug resistance.

Cohort C: Advanced NSCLC patients with MET amplification.

Cohort D: Advanced NSCLC patients with MET exon 14 skipping mutation (Exon14 skipping).

Cohort E: Patients with locally advanced or recurrent metastatic colorectal cancer (CRC) could not undergo curative treatment.

Cohort F: Other advanced solid tumors that have failed or are intolerant to standard therapy.

  • For subjects in the dose escalation phase of Part 1, evaluable lesions must be present; other subjects must have measurable lesions that meet the definition of RECIST v1.1.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
  • Expected survival ≥3 months.

  • For patients with colorectal cancer: patients with colorectal cancer who have previously received systemic anti-tumor therapy beyond the third line (excluding maintenance therapy).
  • For subjects with non-small cell lung cancer only: have received more than 2 prior lines of cytotoxic chemotherapy for locally advanced or metastatic diseases (excluding maintenance therapy).

  • Prior use of EGFR/c-Met bispecific antibody or ADC drugs (such as Amivantamab [JNJ-61186372], EMB-01 or GB263T or AZD9592 etc.).
  • Prior to the first dose of MCLA-129, previous treatment-related toxicities have not resolve to Grade 1 or below (CTCAE 5.0 criteria), except for alopecia.
  • Have had other malignancies within the past 3 years, except for cancers that have been totally cured or locally cured, such as basal or squamous cell carcinoma of the skin, cervical cancer in situ, or breast cancer in situ.
  • Patients with primary malignant tumor of central nervous system, or metastases to meninges, or concomitantly with symptomatic brain metastases, or new therapy naive brain metastases. For cohorts E and F: Patients with known brain metastases and/or meningeal metastases, or primary malignant tumor of central nervous system. Subjects with neurological symptoms shall have a brain CT/MRI scan to exclude brain metastases.
  • With clinically significant cardiovascular and cerebrovascular diseases.
  • Active hepatitis B (positive hepatitis B surface antigen (HBsAg) or core antibody (HBcAb) and serum HBV DNA ≥ 2,000 IU/mL [equivalent to 104 copies/mL]), positive hepatitis C virus antibody, HIV antibody and treponema pallidum antibody.
  • Subjects with a history of interstitial lung disease or current clinical evidence of interstitial lung disease, including drug-induced Interstitial lung disease or radiation pneumonitis.
  • Presence of a serious disease or medical condition currently, including but not limited to uncontrolled active infection, uncontrolled pleural or peritoneal effusion, and clinically significant pulmonary, metabolic or psychiatric diseases.
  • Females of childbearing potential, pregnant or breastfeeding women with a positive serum pregnancy test 7 days before the start of treatment, and male and female subjects who are unwilling to use effective contraceptive measures or plan to have a child throughout the treatment period and within 3 months after the end of treatment.
  • Patients with known allergic reactions and hypersensitivity reactions, or be allergic to MCLA-129 or any of its excipients.
  • Patients with poor compliance, inability or unwillingness to follow the study and/or follow-up procedure listed in the protocol, or patients who are not suitable to participate in this trial, as determined by the investigator.
