A Trial of AK104 or AK112 in Combination With Axitinib in Patients With Metastatic Mucosal Melanoma

Официальное название

A Phase Ib, Open, Mono-center, Dose-reduction Tolerability Study of AK104 or AK112 in Combination With Axitinib in Patients With Metastatic Mucosal Melanoma

Обзор

This study was a phase IB, single-center, open-label, two part(part A involved dose reduction, and part B involved cohort expansion) clinical trial evaluating the safety and clinical activity of AK104 or AK112 in combination with axitinib in patients with advanced mucosal melanoma.

Подробное описание

The planned cohorts in part A were axitinib 5mg twice a day plus AK104 or AK112 every 3 weeks. A minimum of three patients were initially enrolled at the first dose level. If a dose-limiting toxicity occurred, then the cohort would be expanded to a total of six patients. Responses were evaluated by investigators using both RECIST version 1.1 and Immune-Related RECIST (irRECIST). Patients with progressive disease or an intolerant toxicity were taken off the study. Patients who initially developed progressive disease per RECIST version 1.1 were allowed to continue therapy if the investigator considered patients to be benefiting from the treatment per irRECIST. Any dose-reduction cohort that did not exceed the maximum-tolerated dose could be expanded in part B for additional evaluation of safety and clinical activity. The primary end point of this study was dose-limiting toxicity within the first 4 weeks of treatment with AK104 or AK112 plus axitinib in part A.

Left ventricular ejection fraction ≥50%.

Критерии исключения

• Prior treatment with anti-PD-1/PD-L1/PD-L2 antibody and Axitinib
• Is currently participating in a study of an investigational agent or using an investigational device
• Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy within 2 years prior to the first dose of study treatment
• Has undergone major surgery within 30 days of Study Day 1
• Has a known additional malignancy that is progressing or requires systemic treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer

Replacement therapy (e.g., thyroxine, insulin or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment NOTE: Subjects with vitiligo or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study
• Has an active infection requiring systemic therapy
• Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA \[qualitative\] is detected)
• History of myocardial infarction, unstable angina, cardiac or other vascular stenting, angioplasty, or surgery within 12 months prior to day 1 of study treatment
