Dataset Information

Single-arm study of camrelizumab plus apatinib for patients with advanced mucosal melanoma.

ABSTRACT:

Background

Previous studies have suggested the potential synergistic antitumor activity when combining immune checkpoint inhibitors with anti-angiogenic agents in various solid tumors. We aimed to assess the efficacy and safety of camrelizumab (a humanized programmed cell death-1 antibody) plus apatinib (a vascular endothelial growth factor receptor tyrosine kinase inhibitor) for patients with advanced mucosal melanoma (MM), and explore-related biomarkers.

Methods

We conducted a single-center, open-label, single-arm, phase II study. Patients with unresectable or recurrent/metastatic MM received camrelizumab and apatinib. The primary endpoint was the confirmed objective response rate (ORR).

Results

Between April 2019 and June 2022, 32 patients were enrolled, with 50.0% previously received systemic therapy. Among 28 patients with evaluable response, the confirmed ORR was 42.9%, the disease control rate was 82.1%, and the median progression-free survival (PFS) was 8.05 months. The confirmed ORR was 42.9% (6/14) in both treatment-naïve and previously treated patients. Notably, treatment-naïve patients had a median PFS of 11.89 months, and those with prior treatment had a median PFS of 6.47 months. Grade 3 treatment-related adverse events were transaminase elevation, rash, hyperbilirubinemia, proteinuria, hypertension, thrombocytopenia, hand-foot syndrome and diarrhea. No treatment-related deaths were observed. Higher tumor mutation burden (TMB), increased T-cell receptor (TCR) diversity, and altered receptor tyrosine kinase (RTK)/RAS pathway correlated with better tumor response.

Conclusion

Camrelizumab plus apatinib provided promising antitumor activity with acceptable toxicity in patients with advanced MM. TMB, TCR diversity and RTK/RAS pathway genes were identified as potential predictive biomarkers and warrant further validation.

Project description:PurposeImmune checkpoint inhibitors combined with antiangiogenic therapy reportedly have potential synergistic antitumor activity. We investigated the activity and safety of this regimen for recurrent/metastatic nasopharyngeal carcinoma (NPC).MethodsThis single-arm, Simon two-stage study enrolled patients with recurrent/metastatic NPC who were refractory to at least first-line systemic therapy and treatment-naive to immune checkpoint inhibitors. The patients received camrelizumab 200 mg once every 3 weeks and apatinib 250 mg once per day. The primary end point was the objective response rate. Key secondary end points included disease control rate, progression-free survival, duration of response, overall survival, and safety.ResultsBetween October 14, 2020, and December 23, 2021, 58 patients were enrolled, and all were included in the efficacy and safety analysis set. The objective response rate was 65.5% (95% CI, 51.9 to 77.5), and the disease control rate was 86.2% (95% CI, 74.6 to 93.9). The median duration of response was not reached, and the median progression-free survival was 10.4 months (95% CI, 7.2 to 13.6), with a median follow-up duration of 12.4 months (range, 2.1-19.9 months). Treatment-related adverse events (TRAEs) of grade 3 or higher were reported in 34 (58.6%) patients, with the most common being hypertension (19.0%), nasopharyngeal necrosis (15.5%), headache (12.1%), AST elevation (10.3%), and creatine phosphokinase elevation (10.3%). Sixteen (27.6%) patients discontinued apatinib treatment before progression because of unbearable TRAEs, and the most common complication was nasopharyngeal necrosis (9/16; 56.3%). Recurrent nasopharyngeal lesions (odds ratio, 5.94 [95% CI, 1.45 to 24.24]) and reirradiation (odds ratio, 5.33 [95% CI, 1.15 to 24.79]) were significantly positively correlated with nasopharyngeal necrosis.ConclusionCamrelizumab plus apatinib had promising antitumor activity in patients with refractory recurrent/metastatic NPC who failed first-line therapy. Moderate to severe TRAEs were experienced by 58.6%, including nasopharyngeal necrosis associated with local recurrence and a history of reirradiation.

Project description:BackgroundThe combination of anti-programmed death 1 (PD-1) inhibitors and tyrosine kinase inhibitors is an effective treatment strategy in endometrial cancer. We aimed to explore the efficacy and safety of camrelizumab plus apatinib as an alternative therapeutic option in patients with previously treated endometrial cancer.MethodsThis single-arm Simon's two-stage phase II trial was conducted at the Fudan University Shanghai Cancer Center. Patients with advanced or recurrent endometrial cancer who had failed at least one prior systemic therapy were screened for potential participation. Eligible patients were treated with intravenous camrelizumab (200 mg d1 q2w) and oral apatinib (250 mg qd) every 4 weeks. The primary end point was the objective response rate (ORR) per RECIST v1.1 in the intention-to-treat principle.ResultsBetween January 20, 2020, and October 14, 2022, 36 patients (29 with microsatellite stability/mismatch repair proficient [MSS/pMMR] tumors; two with microsatellite instability-high/mismatch repair deficient [MSI-H/dMMR] tumors) were enrolled and treated. The confirmed ORR was 44.4% (95% CI: 27.9, 61.9) and the disease control rate was 91.7% (95% CI: 77.5, 98.2). The median duration of response was 9.3 (95% CI: 4.3, not reached) months, the median progression-free survival was 6.2 (95% CI: 5.3, 11.1) months, and the median overall survival was 21.0 (95% CI: 13.4, not reached) months during a median follow-up of 14.2 (interquartile range: 10.3, 27.6) months. Treatment-related adverse events of grade 3 or 4 occurred in 20 (55.6%) patients, with the most common being increased γ-glutamyl transferase (27.8%), alanine aminotransferase (16.7%) and aspartate aminotransferase (13.9%), and hypertension (11.1%). No treatment-related death occurred.ConclusionsCamrelizumab plus apatinib showed promising antitumor activity with manageable toxicity in patients with advanced or recurrent endometrial cancer who had failed at least one prior systemic therapy. The findings of this study support further investigation of camrelizumab plus apatinib as an alternative therapeutic option, especially for patients with MSS/pMMR tumors.Trial registrationThis trial was retrospectively registered with ChiCTR.org.cn, number ChiCTR2000031932.
