Melanoma Clinical Trial
IN10018 Monotherapy and Combination Therapy for Metastatic Melanoma
This is a phase Ib, open label clinical study to evaluate the safety, tolerability, PK and antitumor activities of IN10018 as monotherapy and in combination with cobimetinib in subjects with metastatic uveal melanoma and NRAS-mutant metastatic melanoma.
Subjects with metastatic uveal melanoma (UM) or with NRAS-mutant metastatic melanoma will be enrolled.
IN10018 will be assessed firstly as monotherapy（Part 1）, then in combination with cobimetinib (Part 2) and in combination with cobimetinib and Atezolizumab (Part 3).
Key Inclusion Criteria:
Ability to understand and willingness to sign informed consent(s).
Male or female subjects ≥ 18 years at the time of signing informed consent.

Metastatic uveal melanoma, or
Metastatic NRAS-mutant melanoma harboring an NRAS activating mutations of Q61, G12, or G13 mutation per local laboratory (including local reference laboratory) results.
Requirements for previous therapy:
Uveal melanoma: Either be treatment naïve or have failed the most recent therapy for metastatic disease, or
NRAS-mutant melanoma: Either be ineligible for standard of care due to the presence of various comorbidities or have failed the most recent therapy such as immunotherapy for metastatic disease.
Have failed immunotherapy therapy (anti-PD-1 or anti-PD-L1) alone or in combination with other agents for metastatic disease either with no initial response or disease progression after an initial response. (Part 3)

Adequate bone marrow, liver, renal, and coagulation function within 5 days prior to first dose of study treatment.
A male subject must agree to use contraception as detailed in Appendix 4 of this protocol during the treatment period and through 30 days after the last dose of study treatment and must refrain from donating sperm during this period.
A female subject is eligible to participate if she is not pregnant, not breastfeeding, and at least 1 of the following conditions applies:
Not a woman of childbearing potential (WOCBP) as defined in Appendix 4. OR
A WOCBP who agrees to follow the contraceptive guidance in Appendix 4 during the treatment period and through 30 days after the last dose of study treatment.
