durvalumab (medi4736) plus cediranib in patients with metastatic uveal melanoma

Conditions: Uveal Melanoma; Metastatic Cancer

Summary: phase ii clinical trial aimed to evaluate the efficacy of the combination of cediranib and durvalumab in patients with metastatic uveal melanoma (mum) with biopsiable disease at first line of after failure to first line systemic or liver directed therapy.


Eligibility criteria:
inclusion criteria: * patients must have histologically confirmed metastatic uveal melanoma with measurable disease not eligible for curative therapy. * participants must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥20 mm with conventional techniques or as ≥10 mm with spiral ct scan, mri, or calipers by clinical exam. patients must have at least 1 biopsiable liver metastasis. * patients can have received one prior therapy for metastatic disease, excepting for treatments listed in exclusion criteria. * patients must be 18 years of age or older at time of study entry. * eastern cooperative oncology group (ecog)

previously treated, off steroids at least 2 weeks, and considered stable. patients with untreated central nervous system (cns) metastases and/or carcinomatous meningitis identified either on the baseline brain imaging \[recist\]) obtained during the screening period or identified prior to signing the icf. patients whose brain metastases have been treated may participate provided they show radiographic stability (defined as 2 brain images, both of which are obtained after treatment to the brain metastases. these imaging scans should both be obtained at least four weeks apart and show no evidence of intracranial progression). in addition, any neurologic symptoms that developed either as a result of the brain metastases or their treatment must have resolved or be stable either, without the use of steroids, or are stable on a steroid dose of ≤10mg/day of prednisone or its equivalent and anticonvulsants, for at least 14 days prior to the start of treatment. brain metastases will not be recorded as recist target lesions at baseline. * patients weighing \<30kg will be excluded from enrollment. * participation in another clinical study with an investigational product during the last 4 weeks. * concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study. * receipt of the last dose of anticancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies) ≤28 days prior to the first dose of study drug if sufficient wash-out time has not occurred due to the schedule or pk properties of an agent, a longer wash-out period will be required, as agreed by sponsor designated coordinating investigator and principal investigator. * any unresolved toxicity nci ctcae grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria: patients with grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the coordinating investigator. patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the coordinating investigator. * any concurrent chemotherapy, imp, biologic, or hormonal therapy for cancer treatment different to cediranib and/or durvalumab. concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable. * radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of study drug. * major surgery within a minimum of 2 weeks prior to inclusion; patients must have recovered from any effects of any major surgery prior to inclusion. note: local surgery of isolated lesions for palliative intent and minor surgeries performed to obtain biological material for the study (i.e. liver biopsy) are acceptable. * history of allogeneic organ transplantation. * active or prior documented autoimmune or inflammatory disorders (including
