About

the efficacy and safety ofhe use of regorafenib in combination with nivolumab

Full description

The present trial consists of a dose-escalation cohort to verify the tolerability of nivolumab and regorafenib when used in combination for patients with solid tumors, and to examine the clinical recommended dose(RD). The trial also consists of an expansion cohort to examine the safety and efficacy when the clinical RD is administered for several advanced solid tumors.

In the dose-escalation cohort, three patients with solid tumors will be administered 3.0 mg/kg of nivolumab once every 2 weeks and regorafenib daily for 21days, with a 1-week washout period at dose of 80 mg (level 1), 120 mg (level 2), or 160 mg (level 3). As a general rule, one cycle will last 28 days (day 1-29); however, in the event of treatment prolongation, the cycle period will be extended. The Dose Limiting Toxicity(DLT) evaluation period will be 28 days. Furthermore, for each level, three additional subjects will be added depending on the state of DLT.

In the expansion cohort, the target subject sample will consist of approximately 30 patients who will be administered 3.0 mg/kg of nivolumab once every 2 weeks, and the clinical RD of regorafenib will be determined in the dose-escalation cohort.

8. For women who are likely to become pregnant (including those without menstruation due to medical reasons such as chemical menopause) Note 1, we agreed to double contraceptive Note 2 for at least 5 months from consent acquisition patient to the final administration of the investigational product. Also, patients who agreed not to breast feeding for at least 5 months from acquiring consent to the final investigational drug administration.

For men, patients agreeing to double contraceptive for at least 7 months from the time of starting investigational drug administration to the final investigational drug administration.

Note 1): A woman who is likely to become pregnant is a woman who has experienced menarche and is not undergoing sterilization surgery (such as hysterectomy, bilateral salpingo ligation or bilateral oophorectomy), a woman without menopause Everything is included. The definition after menopause shall be amenorrhea continuously for 12 months or more even though there is no noteworthy reason. Women who are using oral contraceptives or mechanical contraceptive methods (such as intrauterine contraceptive devices or barrier methods) are considered to be pregnant.

Note 2): With regard to contraception, it is necessary to use two of the vasectomy or condom of a male patient or male male, the uterine tube ligation of a female patient or the other woman, a contraceptive pessary, an intrauterine contraceptive device or an oral contraceptive I need to agree to heavy contraception.
