Drug Information available for: Regorafenib

Arm Intervention/treatment
Experimental: CS1001+Regorafenib
In the dose escalation part, the dose levels will be escalated following a BOIN design. In the dose expansion part, patients will be assigned to different groups based on their tumor types and treated at the RP2D.
Drug: CS1001
CS1001 will be administrated by intravenous (i.v.) infusion once every 28 days

Drug: Regorafenib
The starting dose of regorafenib is 80 mg orally, once daily for the first 21 days of each 28-day cycle.
Other Name: BAY 73-4506




Primary Outcome Measures :
  1. Number of participants with adverse events [ Time Frame: From the day of first dose to 90 days after last dose ]
  2. Dose Limiting Toxicity (DLT) [ Time Frame: First cycle (28 days) ]

Secondary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: To be performed every 8 weeks during treatment period (up to 2 years) ]
  2. Area under the plasma concentration-time curve (AUC) [ Time Frame: From the day of first dose to 30 days after last dose ]
  3. Maximum plasma concentration (Cmax) [ Time Frame: From the day of first dose to 30 days after last dose ]
  4. Time to reach maximum plasma concentration (Tmax) [ Time Frame: From the day of first dose to 30 days after last dose ]
  5. Terminal elimination half-life (t1/2) [ Time Frame: From the day of first dose to 30 days after last dose ]
  6. Anti-CS1001 antibody [ Time Frame: From the day of first dose to 30 days after last dose ]

Criteria

Inclusion Criteria:

  • Participant must have at least one measurable lesion by CT or MRI per RECIST 1.1; radiographic tumor assessment should be performed within 28 days prior to initiation of study treatment.
  • ECOG performance status score of 0 or 1.
  • Life expectancy ≥ 12 weeks.

  • Adequate organ function
  • Women of childbearing potential (WOCBP) must have a negative serum pregnancy test result. Either Female or male participants must agree to use adequate contraceptive measures from signing informed consent and for 180 days after last investigational product administration, except for a participant with documented surgical sterilization or a postmenopausal female.

Exclusion Criteria:

  • Prior malignancy active within the previous 3 years except for locally curable cancers that have been apparently cured.
  • Participants with any condition that impairs their ability to take oral medication, such as lack of physical integrity of the upper gastrointestinal tract or malabsorption syndrome.
  • Has known central nervous system (CNS) metastases and/or carcinomatous meningitis that is either symptomatic or untreated.
  • Any prior or current clinically significant ascites as measured by physical examination and that requires active paracentesis for control.
  • Significant history of cardiac disease within 6 months prior to Day 1 of Cycle 1, myocardial infarction within the previous year, or current cardiac ventricular arrhythmias requiring medication.
  • History or evidence of poorly controlled arterial hypertension.
  • Any serious or uncontrolled medical disorder or active infection may increase the risk associated with study participation or dose.
  • Administration of drugs known as strong CYP3A4 inducers or strong CYP3A4 inhibitors and the last dose was given in < 5 half-lives from the first investigational product administration.

Other inclusion/exclusion criteria may apply.
