A Study to Evaluate the Safety and Tolerability of Using the SHR-1210 in Patients With Advanced Melanoma

Jiangsu HengRui Medicine Co., Ltd.36 enrolled

Overview

This is an open-label, single center, non-randomized, dose escalation phase I trial to evaluate safety and tolerability of SHR-1210 (camrelizumab) in patients with advanced melanoma with disease progression after standard treatment, unresectable lesions, or metastases. Between Apr 13, 2016, and Jan 8, 2020, 36 patients were enrolled from Beijing Cancer Hospital.

Medical Language ↔ Plain English

Inclusion Criteria: 1. Male or female patients aged 18-70 years old, who agree to provide pathological tumor biopsy specimens during the screening period and after the end of treatment. 2. Patients with pathologically confirmed advanced melanoma who have failed standard treatments or without effective treatment methods (e.g., chemotherapy, targeted therapy and immunotherapy other than those targeting PD-1/PD-L1). 3. ECOG PS: 0-1. 4. Life expectancy ≥ 12 weeks. 5. With measurable and evaluable lesion(s) according to RECIST v1.1. Exclusion Criteria: 1. Patients with active autoimmune diseases or a history of autoimmune diseases (including but not limited to the following: interstitial pneumonitis, uveitis, enteritis, hepatitis, hypophysitis, nephritis, vasculitis, hyperthyroidism, hypothyroidism; adults with vitiligo or completely relieved childhood asthma can be enrolled if they do not require any intervention; patients with asthma requiring medical intervention with bronchodilators cannot be enrolled). 2. Patients who are currently using immunosuppressive agents, or systemic or absorbable local hormonal therapies for immunosuppression purposes (\> 10 mg/day prednisone or equivalent) and still use the above drugs within 2 weeks prior to enrollment. 3. Patients who are known to be previously allergic to macromolecular protein preparations or any component of SHR-1210. 4. Patients with clinically symptomatic metastases to central nervous system (e.g., cerebral edema requiring hormonal intervention, or progression of brain metastasis). Patients who have received treatment for brain or meningeal metastasis can be included if they are clinically stable (MRI) for at least 2 months and have discontinued systemic hormonal therapy (\> 10 mg/day prednisone or equivalent) for more than 2 weeks. 5. Patients who have previously received radiotherapy, chemotherapy, hormone therapy, surgery or molecular targeted therapy with an interval of less than 4 weeks from the completion of the treatment to the study medication (for patients who have previously received chemotherapy with nitrosourea or mitomycin, the interval from the end of chemotherapy to the study enrollment is less than 6 weeks); patients whose adverse events caused by previous treatments have not recovered to CTCAE Grade ≤ 1. 6. Patients with active infection or unexplained fever \> 38.5 °C during screening or prior to the first dose (patients with tumor-induced fever may be enrolled as per the judgment of the investigator). 7. Patients with congenital or acquired immunodeficiency (such as HIV, HBV, or HCV). 8. Patients who have previously received other PD-1 antibody treatments or immunotherapies targeting PD-1/PD-L1.

Outcomes

Primary Outcomes

Number of Participants Experiencing Adverse Events (AEs)

The safety assessment documented in this clinical study included any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of an investigational product, which were monitored per the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE version \[v\] 4.03 2010).

Time frame: From the time the participants signed the informed consent to 90 days after the final dose (Up to 3 years and 9 months)

Number of Participants Experiencing Severe AEs (SAEs)

Time frame: From the time the participants signed the informed consent to 90 days after the final dose (Up to 3 years and 9 months)

Secondary Outcomes

Maximum Observed Serum Concentration (Cmax) For SHR-1210

Time frame: PK blood samples are collected multiple times on Cycle 1 (each cycle is 28 days) Day1, Day 8, Day 15, Day 22, Cycle 2 Day 1, Since Cycle 2, every 3 cycle Day 1, and the day disease progression (Up to 3 years and 9 months).

PD-1 receptor occupancy (RO) for SHR-1210

Receptor occupancy (RO) assays are designed to quantify the binding of therapeutics to their targets on the cell surface and are frequently used to generate pharmacodynamic (PD) biomarker data in nonclinical and clinical studies of biopharmaceuticals.

Time frame: PD blood samples are collected multiple times on Cycle 1 (each cycle is 28 days) Day1, Day 8, Day 15, Day 22, Cycle 2 Day 1, Since Cycle 2, every 3 cycle Day 1, and the day disease progression (Up to 3 years and 9 months).

Number of Participants with Anti-drug Antibodies (ADAs) for SHR-1210

ADAs: Immunogenicity was summarized by the number and percentage of participants who developed detectable treatment-emergent ADAs.

Time frame: Blood samples for ADAs analysis are collected on Cycle 1 (each cycle is 28 days) Day1 to the end of treatment (Up to 3 years and 9 months).

Objective Response Rate (ORR)

ORR was defined as the percentage of participants in the study whose best overall response was either complete response (CR) or partial response (PR) as assessed by investigators based on Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1.

Time frame: Up to 3 years and 9 months

Disease Control Rate (DCR)

DCR was defined as the percentage of participants in the study whose best overall response was either CR, PR or stable disease (SD) as assessed by investigators based on Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1.

Time frame: Up to 3 years and 9 months

Progression-free survival (PFS)

PFS was defined as the time from the date of first study dose to disease progression or death whichever occurs first. Participants without an event (no disease progression or death) were censored at the date of "last tumor assessment". Participants with no baseline or post-baseline tumor assessments were censored at Day 1. PFS was based on RECIST v 1.1 and the results of Investigator evaluations. Median PFS was calculated by Kaplan-Meier method.

Time frame: Up to 3 years and 9 months
