Description

Description

Primary Objectives

Secondary Objectives

To demonstrate the effectiveness of volrustomig in combination with carboplatin plus pemetrexed relative to investigator’s choice of nivolumab in combination with ipilimumab or platinum plus pemetrexed by assessment of OS in all randomized participants.

To demonstrate effectiveness of volrustomig in combination with carboplatin plus pemetrexed relative to investigator’s choice of nivolumab in combination with ipilimumab or platinum plus pemetrexed by assessment of PFS.

Inclusion Criteria

Inclusion Criteria

Age

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

Type of Participant and Disease Characteristics

2 All races, genders, and ethnic groups are eligible for this study.

3 Histologically proven diagnosis of PM with known histology (epithelioid vs. nonepithelioid).

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 (that is, ECOG PS > 1) over the previous 2 weeks prior to 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 7 mm to qualify as measurable disease and contribute to the sum that defines the pleural measurement as per mRECIST 1.1 criteria. See Appendix F.

(b) Non-pleural metastatic target lesions measured uni-dimensionally as per RECIST 1.1 criteria. See Appendix F.

(c) Patients who present without pleural lesions that can be considered measurable, but with metastatic lesions (non-pleural) meeting criteria for target lesion by RECIST 1.1 criteria may be considered for inclusion, based upon the investigator’s judgment.

9 Adequate organ and bone marrow function (in the absence of transfusions or growth factor support within 14 days prior to enrollment) as defined below in Table 11. (See protocol)

Weight

10 Body weight > 35 kg.

Sex and Contraceptive/Barrier Requirements

11 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; see below and Appendix G for further details.

(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).

Informed Consent

12 Capable of giving signed informed consent as described in 10 which includes compliance with the requirements and restrictions listed in the ICF and in this CSP.

13 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 (see Appendix D).

Other Inclusion Criteria

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

Exclusion Criteria

Exclusion Criteria

(a) Malignancy treated with curative intent and adequate follow-up with no known active disease or have not required active treatment within the past 2 years before the first dose of study intervention and of low potential risk for recurrence.

(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.

 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.
