A Study of Immunotherapy Drugs Nivolumab and Ipilimumab in Patients w/Resectable Malignant Peritoneal Mesothelioma

A Phase II Prospective, Open-label Trial of Perioperative Combination Nivolumab and Ipilimumab in Patients With Resectable Malignant Peritoneal Mesothelioma

This study is for individuals who have peritoneal mesothelioma, a cancer of the lining of your abdominal wall and organs (the peritoneum). Doctors leading the study would like to determine the effects of treating this cancer with immunotherapy drugs (nivolumab and ipilimumab - the two study drugs that will be used in this study) before and after surgery.

Doctors hope to learn if giving these two drugs before surgery will decrease the amount of viable (live) cancer cells that remain at the time of surgery and whether it will delay the time it could take for the cancer to regrow.

10. Has a known additional malignancy that is progressing or required active treatment within the 3 years prior to enrollment - exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer or other tumors that will not affect life expectancy
11. Has an active infection requiring systemic therapy
12. Has a known history of HIV, Hepatitis B, or Hepatitis C
13. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.

14. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 120 days after the last dose of trial treatment

    1. Female subjects of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
    2. Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication (Reference Section 5.8.2). Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.
    3. Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.
15. Is on anticoagulation that cannot be discontinued in the perioperative period
16. Has received a live vaccine within 30 days of planned start of study therapy

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: All Participants in Study Who Have Mesothelioma; Individuals in this group will receive a combination of two immunotherapy drugs (nivolumab and ipilimumab) before and after surgery to remove their cancer. There will also be a follow up period to determine how well the drugs and surgery worked to get rid of your cancer. Your overall participation in this study (including drug treatment, surgery and follow up visits) will last for roughly one and a half years. All eligible participant who enroll in the study will participate in this group.

Drug: Nivolumab; Nivolumab is an immunotherapy drug (a type of drug that helps your immune system fight cancer) that is often used with ipilimumab as the first treatment in adults with mesothelioma whose disease cannot be removed by surgery. The drug will be given as an IV infusion.; Other Names: BMS-936558; ONO-4538; Opdivo; MDX1106; Drug: Ipilimumab; Ipilimumab is a type of immunotherapy drug known as a checkpoint inhibitor, which helps your own immune system attack cancer cells.; Other Names: Yervoy

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Major Pathologic (Disease) Response of Tumor to Nivolumab Combined With Ipilimumab Before Surgery	The response of participant's tumor to treatment with nivolumab and ipilimumab before surgery by analyzing tissue samples collected from participant during surgery for the presence of cancerous tumour cells. Major pathologic response will be defined as tissue samples containing less than or equal to 10% of residual (leftover) tumor/cancer in the tissue after surgery.	24 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of Participants Who Report Serious Side Effects to Nivolumab Combined With Ipilimumab Before Surgery (Neoadjuvant Treatment)	The rate of participants who report Grade 3 or 4 serious adverse events (side effects) after taking nivolumab combined with ipilimumab before surgery. These side effects will be measured according to Common Terminology Criteria for Adverse Events v5.0 for up to 30 days after surgery.	3 weeks (timeframe for surgery ) + 30 days (timeframe for assessing side effects after surgery)
Number of Participants Who Proceed to Surgery Without Delays After Receiving Nivolumab Combined With Ipilimumab	Number of participants who complete treatment with nivolumab and ipilimumab before surgery and proceed to surgery without extended treatment-related delays or progression precluding surgery as assessed by clinical /study records.	19 weeks
Overall Survival of Participants Who Take Nivolumab Combined With Ipilimumab Before Surgery	Overall survival of participants who receive neoadjuvant nivolumab combined with ipilimumab, defined as time from enrollment on study to death from any cause.	42 Months
Progression-Free Survival of Participants Who Take Nivolumab Combined With Ipilimumab Before Surgery	Progression-free survival of participants who receive neoadjuvant nivolumab combined with ipilimumab, defined as time from enrollment on study to death from any cause.	42 months
Rate of Participants Who Report Serious Side Effects to Taking Nivolumab Combined With Ipilimumab After Surgery (Adjuvant Treatment)	The rate of participants who report Grade 3 or 4 serious adverse events (side effects) after taking nivolumab combined with ipilimumab after surgery. These side effects will be measured according to Common Terminology Criteria for Adverse Events v5.0.	12 weeks
Radiologic Response to Nivolumab and Ipilimumab Before Surgery	Radiologic response to nivolumab and ipilimumab before surgery using radiology images of tumor pre- and post-treatment.	24 months
Peritoneal Carcinomatosis Index (PCI) of Participants Who Taking Nivolumab Combined With Ipilimumab Before Surgery	The effect of nivolumab and ipilimumab on participant's tumor as assessed by a peritoneal carcinomatosis index (PCI) score, a score determined based on the size of participant's tumor after abdominal surgery. The Peritoneal Cancer Index (PCI) scoring system is a diagnostic and prognostic tool. The PCI score is calculated by dividing the peritoneal (abdominal) cavity into 13 regions and assigning a score to each of the 13 regions. Each region receives a score of 0-3 based on the largest tumor size in each region. The total sum of all 13 regions is the PCI score. PCI scores can range from 0 to 39. Higher scores indicate more widespread and/or larger tumors in the peritoneal cavity.	12 weeks
