About
The purpose of this study is to determine the recommended Phase 2 dose (RP2D) of rivoceranib when used in combination with trifluridine/tipiracil in participants with mCRC and to assess progression-free survival (PFS) in participants with mCRC.
Full description
This a multicenter open-label study comparing safety, tolerability and efficacy of rivoceranib and trifluridine/tipiracil monotherapies, and the combination of rivoceranib plus trifluridine/tipiracil in participants with mCRC. Participants with histologically or cytologically definitive adenocarcinoma of the colon or rectum who have progressed following standard of care therapy for colorectal cancer (CRC) will be randomly assigned (1:1:2) to rivoceranib, trifluridine/tipiracil or rivoceranib plus trifluridine/tipiracil treatment groups.
The study will consist of an initial phase 1b portion to assess the safety of and determine the RP2D of rivoceranib in combination with trifluridine/tipiracil. A subsequent phase 2 portion will assess the primary endpoint of progression free survival (PFS) by investigator assessment. When a participant discontinues rivoceranib and/or trifluridine/tipiracil for any reason, the participant will enter the 12-month survival follow-up period until withdrawal of consent from the study, lost to follow-up, end of the study or death, whichever occurs earlier.
The maximum duration of the study is estimated to be 36 months, which includes screening, treatment, and follow-up phases.

Inclusion criteria
Histological or cytological confirmation of the diagnosis of mCRC
Failure to respond or be intolerant of at least 2 prior regimens of standard anti-cancer treatments (study treatment must be 3rd-line or greater for mCRC). Failed prior treatments may include:
Have progressed based on imaging during or within 3 months of the last administration of most recent therapy
Have measurable disease, as defined by RECIST v1.1
Adequate bone marrow, renal, and hepatic function, as evidenced by the following within 7 days prior to Cycle 1 Day 1
Urinary protein <2+ on dipstick or routine urinalysis. If urine dipstick or routine analysis indicates proteinuria ≥ 2+, a 24-hour urine or urine protein/creatinine ratio must be collected and must demonstrate <2 g of protein in 24 hours to allow participation in the study.
Have an Eastern Cooperative Oncology Group (ECOG) status of 0 or 1
Exclusion criteria
Prior treatment with rivoceranib or trifluridine/tipiracil
Prior treatment with other VEGFR small molecule inhibitors (for example, regorafenib)
Packed red blood cell transfusion or erythropoietin therapy within 14 days prior to first dose of study drug
History of another malignancy within 3 years prior to Cycle 1 Day 1. A participant with the following malignancies is eligible for this study if, in the opinion of the Investigator, they do not pose a significant risk to life expectancy:
Active renal dysfunction that requires dialysis treatments
Active cardiac disease including any of the following:
Congestive heart failure New York Heart Association (NYHA) ≥Class 2
Myocardial infarction less than 6 months before the start of Cycle 1 Day 1 of treatment
Cardiac arrhythmias requiring antiarrhythmic therapy (beta-blockers or digoxin are permitted)
History of uncontrolled hypertension (blood pressure ≥140/90 mmHg and/or change in antihypertensive medication within 7 days prior to first dose of study drug)
History of antiangiogenic drug class-related severe adverse reactions, including uncontrolled hypertension or others related to prior therapy discontinuation and/or those that may indicate a higher risk to a participant' safety, in the Investigator's opinion, if provided further antiangiogenic treatment.
History of vascular disease including arterial or venous embolic events (pulmonary embolism), other than hypertension, within 6 months prior to Cycle 1 Day 1 (for example, hypertensive crisis, hypertensive encephalopathy, stroke or transient ischemic attack [TIA], or significant peripheral vascular diseases) that, in the Investigator's opinion, may pose a risk to the participant on VEGF inhibitor therapy.
History of clinically significant thrombosis within 3 months prior to first dose of study drug that, in the Investigator's opinion, may place the participant at risk of side effects from antiangiogenics medications
History of bleeding diathesis or clinically significant bleeding within 14 days prior to first dose of study drug
Therapy with systemic anticoagulant or antithrombotic agents within 7 days prior to first dose of study drug that in the Investigator's opinion could interfere with clotting. The maximum allowable daily dose of aspirin is 325 milligram (mg).
Participants with unstable seizure disorder requiring medication changes within 3 months of Cycle 1 Day 1 treatment
Untreated or active central nervous system (CNS) or leptomeningeal metastases. Participants are eligible if metastases have been treated and participants are neurologically returned to baseline or neurologically stable (expect for residual signs and symptoms related to the CNS treatment) for at least 4 weeks prior to first dose of study drug. In addition, participants must be either off corticosteroids, or on a stable dose or decreasing dose of ≤ 20 mg daily prednisone or prednisone-equivalent. A baseline radiological assessment of the brain will be performed on participants who have prior history of metastases with CNS involvement
History of clinically significant glomerulonephritis, biopsy-proven nephritis, crystal nephropathy or other renal insufficiencies
Unresolved adverse reactions >Grade 1 excluding peripheral neuropathy or treatment related myelosuppression
Known hypersensitivity to any of the study drugs, study drug classes, or any components of study drug formulations
Inability to swallow oral medications
An active malabsorption condition, or any other condition that in the opinion of the Investigator might affect the absorption of study drug
