This study is a single cohort, open label exploratory clinical trial aimed at observing and evaluating the efficacy and safety of Tunlametinib (HL-085) in the treatment of refractory solid tumors with advanced metastatic non melanoma. It is expected that the ORR of Tunlametinib (HL-085) treatment can reach 20%. According to the literature results, the experimental group rate is 0.2 and the target value rate is 0.02. If the bilateral alpha is 0.05 and the beta is 0.2, the sample size is calculated as 12 cases in the experimental group. Considering a 20% dropout rate, a total of 15 cases are required.
