Más betegség

• Active known second malignancy
• Clinically significant cardiac disease
• Infection with human immunodeficiency virus (HIV)-1 or HIV-2 unless it's well-controlled HIV (eg, cluster of differentiation 4 [CD4] > 350/mm3 and undetectable viral load)
• Current active liver disease including hepatitis A (hepatitis A [HepA] virus immunoglobulin M [IgM] positive), hepatitis B (hepatitis B virus [HBV] surface antigen positive), or hepatitis C (hepatitis C virus [HCV] antibody positive, confirmed by HCV RNA)
• Uncontrolled diabetes
• History of solid organ transplantation

• Histologically confirmed ACC or CRC
• Radiographically measurable disease as assessed per RECIST 1.1, with at least 1 site of disease that is measurable and that has not been previously irradiated; or, if the patient has had previous radiation to the target lesion(s), there must be evidence of progression since the radiation
• Patients with locally relapsed/refractory (R/R) advanced or metastatic ACC not amenable to potentially curative surgery or radiotherapy and progression of disease within 12 months at study entry
• Patients with CRC must have locally R/R advanced or metastatic disease not amenable to potentially curative surgery or radiotherapy; must have been previously treated with, or are not considered candidates for, available therapies including fluoropyrimidines-, oxaliplatin-, and irinotecan-based chemotherapies, anti-VEGF agents, and if RAS wild-type, an anti-EGFR therapy.
• Adequate hematologic status, organ function, renal function, liver function and prothrombin time (PT) or INR ≤ 1.5 × ULN and partial thromboplastin time (PTT) or activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN
• Resolved acute effects of any prior therapy to baseline
• Patients with ACC must have documented evidence of intact MYB pseudoexon positive criteria or be MYB wild type and patients with CRC must have amplification of MYB as determined by designated assay
