  • Research summary

    This study will recruit patients with the following cancer indications: ovarian cancer, squamous non-small cell lung cancer, synovial sarcoma and head and neck cancer ; with inoperable locally advanced or metastatic solid tumours. Currently, these patients have a poor prognosis and a relatively short overall survival. There is a lack of meaningful effective therapies available that improve the outcome for these patients.

    The treatment being investigated in this study is ZI-MA4-1, an allogeneic cell therapy product (made with cells from a health dinner). This is the first time ZI-MA4-1 will be administered to humans.

    All participants will receive ZI-MA4-1 administered via IV infusion 3 times per 33-day treatment cycle at their assigned dose. It is planned that all participants in the study will get a minimum of one treatment cycle and up to a maximum of two treatment cycles. Prior to receiving ZI-MA4-1, participants will be given fludarabine and cyclophosphamide to temporarily reduce lymphocytes in the body (lymphodepletion).

    The study is planned to consist of two parts (A and B). Part A includes up to four dose escalation cohorts and aims to identify the maximum tolerated dose of ZI-MA4-1 and give insight into the recommended Phase 2 dose (RP2D). Part B consists of an expansion cohort and is designed to further evaluate the RP2D identified in Part A across one or more indications. The study procedures and eligibility criteria will be the same for participants in Part A and B, except for the dose level of ZI-MA4-1.

    In Part A, a maximum of 24 participants will be enrolled in up to four cohorts with up to six participants each. A maximum of 15 participants will be enrolled in Part B.

    The total duration for participation is approximately 5 years & 2 months [including pre-screening (1 month), screening (23 days), treatment (33 days) and post treatment follow-up period of approximately 5 years)].

    The study is sponsored by Zelluna Immunotherapy AS.
