入选标准
- •Male or female patients ≥18 years of age
- •Diagnosis of uveal melanoma with histological or cytological confirmed metastatic disease. Disease must be treatment naive or have progressed (radiologically or clinically) on most recent therapy.
- •Willingness to provide newly obtained tumor tissue at baseline and on treatment unless contraindicated by medical risk in the opinion of the treating physician.
- •Measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as > 20 mm with conventional techniques or as >10 mm with CT scan.
- •ECOG performance status ≤ 1
排除标准
- •Malignant disease other than that being treated in this study.
- •Symptomatic or untreated CNS metastases or spinal cord compression. Brain metastasis must be stable with verification by imaging .
- •Impaired cardiac function or clinically significant cardiac diseases

- •Patients who are receiving treatment with medications that cannot be discontinued prior to study entry and that are considered to be any of the following:
- •known and possible risk for QT prolongation
- •known to be strong inducers or inhibitors of CYP3A4/5 (for single agent part); known to be moderate to strong inducers or inhibitors of CYP3A4/5 (for combination part)
- •known to be inducers or inhibitors of P-gp
- •known to be substrates of CYP3A4/5 and P-gp with a narrow therapeutic index
- •Patients with abnormal laboratory values, defined as any of the following:
- •AST or ALT > 3 times ULN, AST or ALT > 5 times ULN for patients with liver metastases.
- •Total bilirubin > 1.5 x ULN, except for patients with Gilbert's syndrome who are excluded if total bilirubin > 3.0 x ULN or direct bilirubin > 1.5 x ULN.
- •Absolute neutrophil count (ANC) ≤ 1.5 x109/L.
- •Platelets ≤ 100 x 109/L.
- •Hemoglobin (Hgb) ≤ 90 g/L (9 g/dL).
- •Creatinine > 1.5 x ULN
- •Patients receiving live vaccines due to the expected bone marrow toxicity (applicable to combination part only).
- •Patients treated with growth factors targeting the myeloid lineage (e.g. G-CSF, GM-CSF and M-CSF) within 2 weeks of starting study treatment. (applicable to combination part only).
