 Inclusiecriteria

Participants are eligible to be included in the study only if all of the following criteria apply:

1. Participant must be ≥ 18 years at the time of screening.

2. All races, genders, and ethnic groups are eligible for this study.
3. Histologically proven diagnosis of PM with known histology (epithelioid vs. non-epithelioid).
4. Advanced unresectable disease that cannot be treated with surgery with curative intent (with or without chemotherapy).
5. WHO/ECOG performance status of 0 or 1 with no deterioration over the previous 2 weeks prior to the day of first dosing.
6. Life expectancy ≥ 12 weeks.
7. Provision of existing (leftover) tumor sample obtained within 6 months prior to screening is required, if available.
8. Measurable disease, per investigator assessment, defined as:
– (a) Mesothelioma tumor thickness perpendicular to the chest wall or mediastinum, that can be measured in up to 2 positions at 3 separate levels on transverse cuts of CT scan (cuts must be at least 10 mm apart), for a total of up to 6 measurements. Each single tumor measurement must be at least 10 mm to qualify as measurable disease and contribute to the sum that defines the pleural measurement.
– (b) Non-pleural metastatic target lesions measured unidimensionally as per RECIST 1.1 criteria.
– (c) Patients who present without pleural lesions that can be considered measurable, but with metastatic lesions meeting criteria for target lesion by RECIST 1.1 criteria may be considered for inclusion, based upon the investigator’s judgment.

9. Body weight > 35 kg.

10. Male and/or female. Contraceptive use by males or females should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies
– (a) Male participants: Non-sterilized male participants who are sexually active with a female partner of childbearing potential must use a condom with spermicide from enrolment until at least 90 days after the last dose of volrustomig, and 180 days after the last dose of pemetrexed or carboplatin (Note: Male condoms are not reliable as a sole contraception method). IT IS STRONGLY RECOMMENDED THAT female partners of a male participant also use at least one highly effective method of contraception throughout this period. In addition, male participants must refrain from fathering a child or donating sperm from enrolment, throughout the study, and until at least 90 days after the last dose of volrustomig, and 180 days or per local prescribing information after the last dose of all other study treatments.
– (b) Female participants:
– Females receiving HRT and whose menopausal status is in doubt will be required to use one of the contraception methods outlined for females of childbearing potential if they wish to continue using HRT during the study. Otherwise, HRT must be discontinued to allow confirmation of post-menopausal status prior to study enrolment.
– If sexually active with a non-sterilized male partner, female participants of childbearing potential must use at least one highly effective method of birth control from enrolment, throughout the study, and until at least 90 days after the last dose of volrustomig, and 180 days or per local prescribing information after the last dose of all other study treatments.
– All females of childbearing potential must have a negative serum pregnancy test result at Visit 1 (ie, during the screening period).

11. Capable of giving signed informed consent as described in Appendix A, which includes compliance with the requirements and restrictions listed in the ICF and in this CSP.
12. Provision of signed and dated written Optional Genetic Research Information informed consent prior to collection of samples for optional genetic research that supports the Genomic Initiative.

13. Prior palliative radiotherapy is permitted, but at least 14 days must elapse prior to first dose and all signs of toxicity must be resolved.

 Exclusiecriteria

Participants are excluded from the study if any of the following criteria apply:

1. As judged by the investigator, any condition that would interfere with evaluation of the investigational product or interpretation of participant safety or study results.
2. History of another primary malignancy except for:

– (b) Adequately treated nonmelanoma skin cancer or lentigo maligna without evidence of disease.
– (c) Adequately treated carcinoma in situ, including Ta bladder tumors, without evidence of disease. Cancer participants with incidental histologic findings of prostate cancer that, in the opinion of the investigator, is not deemed to require active therapy (eg, incidental prostate cancer identified following cystoprostatectomy that is tumor/node/metastasis stage ≤ pT2N0) may be enrolled, pending discussion and approval by the investigator.
3. Active or prior documented autoimmune or inflammatory disorders including inflammatory bowel disease (eg, colitis or Crohn’s disease), diverticulitis (with the exception of diverticulosis), celiac disease, systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome (granulomatosis with polyangiitis), Graves’ disease, rheumatoid arthritis, hypophysitis, uveitis, pneumonitis (past medical history of ILD, drug-induced ILD, or radiation pneumonitis requiring steroid treatment, or any evidence of clinically active ILD), etc. The following are exceptions to this criterion:
– (a) Participants with vitiligo or alopecia.
– (b) Participants with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement.
– (c) Any chronic skin condition that does not require systemic therapy.
– (d) Participants without active disease in the last 5 years prior to enrolment may be included.
– (e) Participants with celiac disease controlled by diet alone.
4. History of active primary immunodeficiency.
5. Untreated or progressive CNS metastatic disease, any leptomeningeal disease, or cord compression. Exceptions include:
– Participants previously treated with radiation or surgical resection within 3 months prior to first dose of investigational products for CNS metastases who are asymptomatic, and clinically stable who do not require corticosteroids for at least 14 days prior to the first dose of investigational product.
6. As judged by the investigator, any evidence of diseases (such as severe or uncontrolled systemic diseases, including, but not limited to, ongoing or active infection, cardiomyopathy of any etiology, symptomatic congestive heart failure [as defined by New York Heart Association class > 2], uncontrolled hypertension, unstable angina pectoris, history of myocardial infarction within the past 12 months, ILD, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations, and active bleeding diseases) and/or history of organ transplant or allogeneic stem cell transplant, which, in the investigator’s opinion, makes it undesirable for the participant to participate in the study or that would jeopardize compliance with the protocol.
7. Evidence of the following infections:
– (a) Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination, and radiographic findings and tuberculosis testing in line with local practice).
