Brief Summary:
This phase I/II studies the side effects and best dose of regorafenib when given together with pembrolizumab in treating participants with colorectal cancer that has spread to other places in the body. Drugs used in chemotherapy, such as regorafenib, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Giving regorafenib and pembrolizumab may work better at treating colorectal cancer.

Condition or disease Intervention/treatment Phase
Colorectal Cancer Colorectal Cancer Metastatic Biological: Pembrolizumab Drug: Regorafenib Phase 1 Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. To assess safety of the combination and identification of the recommended dose (RD) for combination therapy. (Phase I) II. To evaluate preliminary efficacy and tolerability of the combination RD of regorafenib and pembrolizumab. (Phase II)

EXPLORATORY OBJECTIVES:

I. The associations between biomarkers and clinical outcome will be investigated.

OUTLINE: This is a phase I, dose-escalation study of regorafenib followed by a phase II study.

Participants receive pembrolizumab intravenously (IV) over 30 minutes on day 1 and regorafenib orally (PO) once daily (QD) on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, participants are followed up periodically.

Primary Outcome Measures :
  1. Dose limiting toxicity (DLTs) (Phase I) [ Time Frame: At the end of Course 1 (each course is 21 days) ]
    Will be evaluated according to Common Terminology Criteria for Adverse Events (CTCAE) version (v)4.03. All DLTs will be listed by dose level.

  2. Progression-free survival (PFS) (Phase II) [ Time Frame: Up to 30 months after study entry ]
    PFS will be calculated from the start of treatment (day 1 of cycle 1) to the first observation of disease progression or death whichever comes first, or to the latest follow up. Kaplan Meier curves will be used for PFS plot. Medians and probabilities of PFS at 3 and 6 months and their 95% CI confidence intervals will be given.

  3. Overall survival (OS) [ Time Frame: Up to 30 months after study entry ]
    OS will be calculated from the start of treatment (day 1 or cycle 1) to death from any cause. Kaplan Meier curves will be used to OS plot. Medians and probabilities at 3 and 6 months and their 95%CI confidence intervals will be given.

  • Total bilirubin =< 1.5-times the upper limit of normal
  • Creatinine =< 1.5-times the upper limit of normal
  • Lipase =< 1.5 x the upper limit of normal (ULN)
  • International normalized ratio (INR) =< 1.5 x ULN and partial thromboplastin time (PTT) or activated partial thromboplastin time (aPTT) =< 1.5 x ULN unless receiving treatment with therapeutic anticoagulation. Patients being treated with anticoagulant, e.g. heparin, will be allowed to participate provided no prior evidence of an underlying abnormality in these parameters exists. Close monitoring of at least weekly evaluations will be performed until INR and PTT are stable based on a pre-dose measurement as defined by the local standard of care

Women with the potential for pregnancy include those who have begun menstruation, who have not undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy, and who have not gone through menopause. Menopause is defined as the consecutive absence of menstrual periods for >= 12 months
  • In the case of men, the patient must agree after consenting to the study to take contraception for at least 31 weeks after taking the final dose of the investigational drug (a period of 90 days [the spermatogenesis cycle] is added to five times the elimination half-time of immuno-oncology (I/O) agent

  • Therapeutic anticoagulation with vitamin-K antagonists (e.g., warfarin) or with heparins and heparinoids. However, prophylactic anticoagulation as described below is allowed:

    • Low dose warfarin (1 mg orally, once daily) with PT-INR =< 1.5 x ULN is permitted. Infrequent bleeding or elevations in PT-INR have been reported in some subjects taking warfarin while on regorafenib therapy. Therefore, subjects taking concomitant warfarin should be monitored regularly for changes in PT, PT-INR or clinical bleeding episodes

  • During the study, strong CYP3A4 inhibitors (eg, clarithromycin, grapefruit juice, indinavir, itraconazole, ketoconazole, nefazodone, nelfinavir, posaconazole, ritonavir, saquinavir, telithromycin, voriconazole) or strong CYP3A4 inducers (eg, carbamazepine, phenobarbital, phenytoin, rifampin, St. John?s wort) are not permitted
  • Live vaccines administered < 30 days before the initiation of treatment with the investigational drug and during the trial period. Examples of live vaccines are as follows (however, the list is not exhaustive): measles, mumps, rubella, chicken pox/herpes zoster, yellow fever, rabies, BCG for tuberculosis, and typhoid vaccines. Inoculation with inactive vaccines (e.g., seasonal influenza vaccines) is permitted; however, the intranasal administration of attenuated influenza vaccines (e.g., Flu-Mist) is prohibited
  • Systemic glucocorticoids for purposes other than treating symptoms caused by notable events with a suspected immunological etiology. Upon deliberation with the trial coordinating committee, the use of corticosteroids may be permitted according to the physiological dose required to alleviate symptoms (e.g., to control symptoms of acute asthma)
