Inclusion criteria
. Is able to complete signed informed consent. Patients for whom English is not their primary language are eligible for participation with translator assistance during the informed consent process.
. Is of age ≥ 18
. Is able, in the investigator's judgment, to comply with the study protocol
. Has measurable disease according to RECIST v1.1 The pleural mesothelioma cohort will require measurable disease according to either modified RECIST or RECIST; the Hodgkin lymphoma patients will be assessed by the 2014 Lugano criteria (see Appendix F)
. Has an ECOG performance status of 0 - 1
. Has adequate hematologic and end-organ function, defined by the following laboratory test results, obtained within 14 days prior to initiation of study treatment:
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
To establish the efficacy of XmAb20717 as measured by overall response rate.
Timeframe: through study completion, an average of 1 year
. Must agree to use a highly effective method of birth control (as defined in Section 7.4.1) (female patients and male patients with female partners of childbearing potential) during and for 6 months after last dose of study treatment. Also see related information in Section 6.6.10.8.
. Peritoneal Mesothelioma: Has advanced MPeM that was previously treated with and refractory/intolerant to platinum-pemetrexed systemic chemotherapy or has not received treatment and is ineligible for platinum-pemetrexed treatment
Exclusion criteria
. Cervical Cancer: Has recurrent, metastatic, or persistent cervical cancer (squamous cell carcinoma, adenosquamous, or adenocarcinoma of the cervix) and has received at least one prior line of systemic therapy and not amenable to curative treatment. Prior treatment with anti-PD1 / PDL1 antibody is not exclusionary.
. Small-cell lung cancer: Extensive-stage small-cell lung cancer following treatment with prior platinum-based therapy, which can include prior anti-PD1, anti-PDL1, but not anti-CTLA4.
. Received treatment for the studied cancer within 21 days prior to initiation of study treatment
. Received treatment with targeted therapies or investigational therapies within 21 days or for the duration of 5 half-lives prior to initiation of study treatment
. Has a history of severe allergic, anaphylactic, or other hypersensitivity reactions to study drug
. Has active known- or suspected autoimmune disease (allowed are patients with vitiligo; type 1 diabetes mellitus, or residual hypothyroidism due to an autoimmune condition that is treatable with hormone-replacement therapy only; psoriasis, atopic dermatitis, or another autoimmune skin condition that is managed without systemic therapy; or arthritis that is managed without systemic therapy beyond oral acetaminophen and non-steroidal anti-inflammatory drugs).
. Has any condition that requires systemic treatment with corticosteroids, prednisone equivalents, or other immunosuppressive medications within 14 days prior to first dose of study drug (except that inhaled or topical corticosteroids or brief courses of corticosteroids given for prophylaxis of contrast dye allergic response are permitted).
. Has a history or evidence of any other clinically unstable/uncontrolled disorder, condition, or disease (including, but not limited to, cardiopulmonary-, renal-, metabolic-, hematologic-, or psychiatric-) other than their primary malignancy, that in the opinion of the Investigator would pose a risk to patient safety or interfere with study evaluations, procedures, or completion.
