* Eastern Cooperative Oncology Group (ECOG) performance status 0, 1 or 2, (not declining within 2 weeks prior to the first dose of investigational product);
* Life expectancy - 12 weeks or more from the moment of randomization;
* Presence of at least 1 measurable tumour with a size not less than 1 cm (revealed with CT slice thickness not more than 5 mm), as defined by modified Response Evaluation Criteria in Solid Tumors (RECIST) criteria (specifically, no ascites, pleural, or pericardial effusions, osteoblastic bone metastases, or carcinomatous lymphangitis of the lung as only lesion;
* Patients should be able to follow the Protocol procedures (according to Investigator's assessment);
* Patients must implement reliable contraceptive measures during all the study treatment, starting 4 weeks prior to the administration of the first dose of investigational product until 6 months after the last dose of investigational product. This requirement does not apply to participants who have undergone surgical sterilization, or patients who are postmenopausal (documented) for the past 2 years. Reliable contraceptive measures include two methods of contraception, including one barrier method
