A Study of TRK-950 in Combinations With Anti-Cancer Treatment Regimens in Patients With Advanced Solid Tumors

Prior treatment

• Treatment with radiation therapy within 2 weeks, or treatment with surgery, chemotherapy, immunotherapy, targeted therapy or investigational therapy within four weeks prior to initiation of study treatment (6 weeks for nitrosoureas or mitomycin C, and 2 weeks or 5 half-lives whichever is longer for TKIs).
• Patients who are currently receiving any other investigational agent

Other illness

• New York Heart Association Class III or IV, cardiac disease, myocardial infarction within the past 6 months, unstable arrhythmia, or evidence of ischemia on ECG
• Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy. Prophylactic antibiotics are acceptable.
• Known active infection with HIV, hepatitis B, hepatitis C
• Serious nonmalignant disease that could compromise protocol objectives in the opinion of the investigator and/or the sponsor
• Any contraindicated condition or drug which would make the patient ineligible for the respective treatment regimen that is to be used in combination with TRK-950 (for example, autoimmune disorders for nivolumab or pembrolizumab treatment) as described in the Full Prescribing Information
