Study Details

Study Description

Brief Summary

Patients with advanced mismatch repair-deficient (MMRd) or microsatellite instability-high (MSI-H) endometrial cancer (EC) are currently treated as one entity, and immune checkpoint inhibitor (ICI) monotherapy is the treatment of choice. However, different molecular mechanisms drive the development of dMMR/MSI-H tumors, including germline mutations in canonical MMR genes (Lynch syndrome), somatically acquired MMR gene mutations (Lynch-like), and homozygous methylation of the MLH1 gene promoter (sporadic). There is increasing evidence that patients with sporadic MMRd EC have a worse response to ICI monotherapy than those with Lynch/Lynch-like tumors. Antiangiogenic therapy can relieve immunosuppression through blood vessel normalization and the oxygen metabolism pathway, thereby having a synergistic effect with ICIs. Anlotinib is an oral anti-angiogenic tyrosine kinase inhibitor (TKI). Camrelizumab is a fully humanized, high-affinity monoclonal antibody against PD-1. The purpose of this trial is to assess the efficacy and safety and tolerability of anlotinib plus camrelizumab in recurrent EC patients with sporadic MMRd tumors.

Outcome Measures

Primary Outcome Measures

  1. Objective response rate (ORR) [24 months]

    ORR is defined as the percentage of patients, relative to the total of enrolled subjects, achieving a complete (CR) or partial (PR) response, according to RECIST 1.1 criteria.

Secondary Outcome Measures

  1. Frequency and severity of adverse events (AEs) [24 months]

    Number of participants with AEs occurring up to 28 days after the last administration are evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.03.

  2. Progression-free Survival (PFS) [24 months]

    The duration from date of enrollment to the disease progression, death, or the date of last contact, whichever occurs first.

  3. Overall Survival (OS) [24 months]

    The duration from date of enrollment to time of death or the date of last contact, , whichever occurs first.

  4. Disease Control Rate (DCR) [24 months]

    The percentage of participants in the analysis population who have a CR, PR or SD as assessed by RECIST 1.1.

  5. Duration of Response (DOR) [24 months]

    the time from first documented CR or PR until disease progression or death due to any cause, whichever occurs first.

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years and Older
Sexes Eligible for Study:
Female
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  1. Patients must receive have completed at least 1 but no more than 3 prior lines of therapy including at least one prior platinum-based chemotherapy:
  • Patients with recurrent endometrial cancer that has failed at least one line of platinum-based chemotherapy;

  • Patients with newly diagnosed advanced (metastatic and/or unresectable) disease has persist lesion after frontline treatment with surgery and platinum-based chemotherapy ± radiotherapy;

  • Patients with newly diagnosed advanced disease that is not amenable to curative treatment with surgery and/or radiation therapy cannot tolerate chemotherapy;

  1. Patients may have received prior hormonal therapy for treatment of endometrial carcinoma. All hormonal therapy must be discontinued at least one week prior to the first date of study therapy.

  2. Histologically proven diagnosis of endometrial cancer.

  3. Tumors must demonstrate MMRd and MLH1 methylation.

° Endometrial tumor MMR and MLH1 methylation status: All participants must be screened using Immunohistochemistry (IHC) for MMR proteins MLH1, MSH2, MSH6, and PMS2. MLH1 gene promoter methylation is performed in tumors exhibiting MLH1 and/or PMS2 IHC loss. MLH1 methylation status is determined by the bisulfite mediated detection of methylated cytosines, as described by Benhamida (Benhamida JK, et al. Reliable Clinical MLH1 Promoter Hypermethylation Assessment Using a High-Throughput Genome-Wide

Methylation Array Platform. J Mol Diagn. 2020 Mar;22:368-375. doi:

10.1016/j.jmoldx.2019.11.005).

  • Hemoglobin ≥ 80 g/L;

  • Total bilirubin ≤ 1.5 x upper limit of normal (ULN);

  • Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ≤ 2.5 × ULN (however, patients with known liver metastasis who have AST or ALT level ≤ 5 × ULN may be enrolled);

  • Creatinine ≤ 1.5 × ULN or creatinine clearance rate ≥ 60 ml/min (Cockcroft-Gault formula);
