简要总结
The primary goal of this Phase 1 study is to characterize the safety and tolerability of INCMGA00012 and establish the maximum tolerated dose (MTD) of INCMGA00012 administered on either every two week or every four week schedules of administration among patients with solid tumors. Pharmacokinetics, pharmacodynamics, and the anti-tumor activity of INCMGA00012 will also be assessed.
The purpose of Amendment 5 is to obtain additional safety experience at the newly defined recommended Phase 2 dose of 500 mg every 4 weeks in patients with endometrial cancer, specifically either microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR). Additionally, every 3 week (Q3W) flat-dosing will be studied in an additional tumor agnostic cohort.
详细描述
This study is a Phase 1, open-label, dose escalation and cohort expansion study designed to characterize the safety, tolerability, PK, PD, immunogenicity, and preliminary anti-tumor activity of INCMGA00012 administered IV every 2, 3, or 4 weeks in patients with relapsed/refractory, unresectable locally advanced or metastatic solid tumors.
In the initial phase of the study, two dose schedules will be assessed in dose escalation, once every two weeks and once every four weeks administration of single agent INCMGA00012. Following the establishment of an MTD, additional patients will enroll in expansion cohorts of specific tumor types and/or INCMGA00012 dose.
The Cohort Expansion Phase will include tumor-specific cohorts, consisting of patients with endometrial cancer (unselected [up to n = 35] and MSI-H or dMMR [up to n = 70]), cervical cancer (up to n = 35), sarcoma (up to n = 35), non-small cell lung cancer (NSCLC) (up to n = 35), and 3 cohorts of any tumor histology (tumor-agnostic) (up to n = 15) who will receive flat dosing: 1 cohort treated with INCMGA00012 500 mg Q4W, 1 cohort with INCMGA00012 750 mg Q4W, and 1 cohort treated with INCMGA00012 375 mg Q3W.

入选标准
- •Histologically proven, locally advanced unresectable or metastatic solid tumors for whom no approved therapy with demonstrated clinical benefit is available or standard treatment was declined. Patients enrolled to Cohort H (endometrial cancer 500 mg Q4W) must have MSI-H or dMMR endometrial cancer, as determined by a local laboratory using IHC or PCR methods and must also have tissue (fresh or archival) available for central confirmation of diagnosis
- •Expansion cohort(s): Progression during or following at least 1, and up to 5, previous systemic therapies, consistent with the standard of care for the specific tumor type.
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- •Life expectancy ≥ 12 weeks
- •Measurable disease
- •Acceptable laboratory parameters
排除标准
- •Symptomatic central nervous system (CNS) metastases.
- •For Cohort Expansion, patients who have previously received an immune checkpoint inhibitor (e.g., anti-PD-L1, anti-PD-1, anti-CTLA-4) are not eligible for this study.
- •Patients with any history of known or suspected autoimmune disease with the specific exceptions of vitiligo, resolved childhood atopic dermatitis, psoriasis not requiring systemic treatment (within the past 2 years), and patients with a history of Grave's disease that are now euthyroid clinically and by laboratory testing.
- •Treatment with any systemic anti-neoplastic therapy, or investigational therapy within the 4 weeks prior to the initiation of study drug administration.
- •Treatment with radiation therapy within 2 weeks prior to the initiation of study drug administration.
- •Clinically significant cardiovascular disease
- •Clinically significant pulmonary compromise, including a requirement for supplemental oxygen use to maintain adequate oxygenation.
- •Presence of active pneumonitis or history of non-infectious pneumonitis.
- •Clinically significant gastrointestinal disorders
- •Evidence of active viral, bacterial, or systemic fungal infection requiring parenteral treatment within 7 days prior to the initiation of study drug. Patients requiring any systemic antiviral, antifungal, or antibacterial therapy for active infection must have completed treatment no less than one week prior to the initiation of study drug
- •Known history of positive testing for human immunodeficiency virus or history of acquired immune deficiency syndrome.
- •Known history of hepatitis B or hepatitis C infection or known positive test for hepatitis B surface antigen, hepatitis B core antigen, or hepatitis C polymerase chain reaction (PCR)
- •Vaccination with any live virus vaccine within 4 weeks prior to the initiation of study drug administration. Inactivated annual influenza vaccination is allowed
- •Dementia or altered mental status that would preclude understanding and rendering of informed consent
