Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients with malignant pleural mesothelioma stage I-III who have undergone cytoreductive surgery with curative intend consisting of extended pleurectomy / decortication (eP/D) with or without hyperthermic intrathoracic chemoperfusion (HITOC) who will receive a maximum treatment duration of 16 cycles (4 cycles of chemotherapy in both arms + 12 cycles maintenance immunotherapy in treatment arm B). The main objective of the trial is Time-to-next-treatment (TNT), as well as safety and tolerability.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, randomized, controlled, open-label study including patients with malignant pleural mesothelioma (MPM) in tumor stages I-III who have previously undergone cytoreductive surgery by extended pleurectomy/decortication with or without hyperthermic intrathoracic chemoperfusion (eP/D ± HITOC).

Patients who have histologically proven initial diagnosis of malignant pleural mesothelioma of epithelioid subtype (including biphasic histologic subtype identified during surgery), will be included in this study. Patients must have confirmed Eastern Cooperative Group (ECOG) status 0 to 2 as well to able to be included to the study.

Patients will be centrally randomized 1:1 to receive either platinum-based adjuvant chemotherapy iv (Arm A) or platinum-based adjuvant chemotherapy iv together with nivolumab (Arm B) and stratified to (HITOC (yes vs. no)), (ECOG (0,1 vs. 2)), (Result of prior resection (macroscopic complete vs incomplete resection) with macroscopic complete resection defined as residual amounts of tumor being less than 1 cm3.

Arm A (platinum-based adjuvant chemotherapy iv) patients randomized to Arm A will receive 4 cycles (q4w) chemotherapy i.v. (carboplatin AUC5 (area under curve) or cisplatin 75 mg/m2 and pemetrexed 500 mg/m2). Usually, pemetrexed is administered first as a 10 min infusion, followed by infusion of the platinum component (starting 30 min after pemetrexed infusion). Active treatment within this arm is limited to 4 months.

Arm B (platinum-based adjuvant chemotherapy iv) patients randomized to Arm B will receive 4 cycles (q4w) chemotherapy i.v. (carboplatin AUC5 (area under curve) or cisplatin 75 mg/m2 and pemetrexed 500 mg/m2) together with up to 12 cycles (q4w) maintenance immunotherapy with nivolumab iv (480mg fixed dose over 60 minutes). During cycles 1-4, when nivolumab is administered along with chemotherapy, nivolumab will be administered as the first infusion, followed by the chemotherapy components. Subjects may be dosed with nivolumab i.v. no less than 26 days from the previous dose of drug. Active treatment within this arm is limited to 16 cycles (4 cycles adjuvant combination therapy + 12 cycles maintenance immunotherapy).

Tumor tissue, blood and stool samples will be collected for accompanying research project. (Participation is optional for participant).

During treatment, clinical visits (blood cell counts, ECG, detection of toxicity) occur prior to every treatment dose. Safety of chemotherapy/nivolumab will be monitored continuously by careful monitoring of all adverse events (AEs) and serious adverse events (SAEs) reported.

During treatment, tumor response will be assessed by the Investigator according to modified RECIST for pleural lesions and RECIST 1.1 for non-pleural lesions (radiological imaging by CT and/or MRI of the chest and upper abdomen \[including the entire liver and both adrenal glands\] at 8 weeks (±7days) from the date of first drug administration, at 16 weeks (±7 days) and every 12 weeks (±7 days) thereafter, until the initiation of the next anti-cancer therapy or death. A post-End-of-Treatment anticancer therapy status (EOT and follow-up (FU)) as well as a Survival Status (follow-up (FU)) will be assessed 30 days-, 100 days- and every 12 weeks after End of Treatment (EOT).

Inclusion Criteria

1. Fully-informed written consent
2. Males and females ≥ 18 years of age
3. Histologically proven initial diagnosis of malignant pleural mesothelioma of epithelioid subtype (patients can also be included if biphasic histologic subtype has been identified during surgery)
4. Postoperative stage I-III (TNM 8th Edition; pT1-4, pN0-2, cM0). Patients are only included with a completeness of cytoreduction score (CC score) \<3 (i.e., residual tumor thickness ≤2.5 cm).
5. Patients must have undergone cytoreductive surgery with curative intent consisting of extended pleurectomy/decortication (eP/D) ± hyperthermic intrathoracic chemotherapy (HITOC) performed
6. Surgery conducted ≤12 weeks (≤84 days) before study inclusion and patient recovered from post-surgical complications of eP/D or eP/D + HITOC
7. Eastern Cooperative Oncology Group (ECOG) performance status 0-2
8. Female patients with reproductive potential must have a negative urine or serum pregnancy test within 7 days prior to start of trial. Women must not be breastfeeding.
9. The patient is willing and able to comply with the protocol for the duration of the study, including hospital visits for treatment and scheduled follow-up visits and examinations.
10. WOCBP must agree to follow instructions for method(s) of contraception for a period of 30 days (duration of ovulatory cycle) plus the time required for the investigational drug to undergo 5 half-lives. The terminal half-lives of nivolumab is approximately 25 days. WOCBP should use an adequate method to avoid pregnancy for approximately 5 months (30 days plus the time required for nivolumab to undergo 5 half-lives) after the last dose of investigational drug.
