A Study of RC48-ADC in Advanced Melanoma Subjects With HER2 Variant (Mutation, Amplification, Overexpression)
Sponsor:

RemeGen Co., Ltd.

Brief Summary:

This is a Phase IIa, single-arm, multicentre, open-label clinical trial aims to evaluate the effectiveness and safety of RC48-ADC in the treatment of HER2 Variant (Mutation, Amplification, Overexpression) advanced melanoma.

Condition or disease

Melanoma, Stage II

HER2-positive

Advanced Melanoma

Intervention/treatment

RC48-ADC

Phase

Phase 2

Detailed Description:

This study is a phase IIa multicentre,single-arm, open-label, clinical study to evaluate the efficacy and safety of recombinant humanized anti-HER2 monoclonal antibody-Monomethyl auristatin E (MMAE) conjugate for the treatment of HER2- positive advanced melanoma. HER2 mutation is defined as the presence of HER2 gene mutations in primary or metastatic tumour tissue as detected by immunohistochemistry (IHC). HER2 gene mutation.}}

Criteria
Inclusion Criteria

  • All female subjects will be considered to be of child-bearing potential unless participants are postmenopausal, or have been sterilized surgically.Female subjects of child-bearing potential must agree to use two forms of highly effective contraception. Male subjects and their female partner who are of child-bearing potential must agree to use two forms of highly effective contraception.
  • Willing to adhere to the study visit schedule and the prohibitions and restrictions specified in this protocol.
  • Adequate organ function.
  • All subjects must be histologically confirmed, non-resectable stage III or metastatic melanoma, except for patients with uveal or ocular melanoma.
  • The subject has experienced disease progression or intolerance after receiving standard treatment in the past; Patients with disease progression within 6 months after receiving neoadjuvant or adjuvant chemotherapy regimens can be included in the clinical study.
  • The HER2 IHC test result is IHC 2+ or IHC 3+, the subject's previous test results (confirmed by the investigator) or the research center's test results are acceptable; the subject can provide the Specimen of primary or metastatic tumor for HER2 review/judgment.
  • According to the RECIST 1.1 standard, there is at least one measurable lesion.
Exclusion Criteria
  • Known hypersensitivity to Recombinant Humanized Anti-HER2 Monoclonal Antibody-MMAE Conjugate For Injection.
  • History of receiving any anti-cancer drug/biologic treatment within 4 weeks prior to trial treatment.
  • Pleural or abdominal effusion with clinical symptoms that requires ongoing treatment.
  • Treated with systemic treatment (e.g. immunomodulators, corticosteroids or immunosuppressants) for the autoimmune disease within 2 years prior to the study treatment.
  • History of major surgery within 4 weeks of planned start of trial treatment.
  • Has received a live virus vaccine within 4 weeks of planned start of trial treatment.
  • Toxicity of previous anti-tumor treatment not recovered to CTCAE Grade 0-1 (with exception of Grade 2 alopecia).
  • Pregnancy or lactation.
  • Currently known active infection with HIV or tuberculosis.
  • Diagnosed with HBsAg, HBcAb positive and HBV DNA copy positive, or HCVAb positive.
  • Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
  • History of other malignancy within the previous 5 years, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, or cancers with a similar curative outcome as those mentioned above.
  • Assessed by the investigator to be unable or unwilling to comply with the requirements of the protocol.
