Melanoma, Ocular Clinical Trial
Official title:
A Single-arm, Multi-Center, Open-Label Study to Evaluate the Efficacy, Safety and Pharmacokinetics of Melphalan/HDS Treatment in Patients With Hepatic-Dominant Ocular Melanoma
This study will evaluate patients who have melanoma that has spread from the eye to the liver: Patients in the study will be treated with Melphalan/HDS up to 6 total treatment, and will be followed until death. This study will evaluate the safety and effects of the treatment on how long patients live and how long it takes for the cancer to advance or respond to the treatment.
The study will consist of 3 phases: a screening phase, treatment phase, and follow-up phase. Screening Phase: Screening assessments will be conducted within 28 days prior to the eligibility date to determine each patient's overall eligibility and baseline characteristics. These assessments will include medical history, physical examination, Eastern Cooperative Oncology Group (ECOG) performance status (PS), 12 lead electrocardiogram (ECG), echocardiogram (ECHO), vital signs, full hematology and biochemistry, Quality of Life questionnaire, radiologic assessments of baseline disease status and concomitant medications. For patients with a history of liver surgery or major vasculature surgery, an angiogram evaluation of their vasculature will be performed for compatibility for Percutaneous Hepatic Perfusion (PHP) prior to confirming eligibility. Eligibility date: This is the date on which all screening assessments have been completed and the patient is determined to be eligible for the trial. Treatment Phase: Eligible patients will be treated with Melphalan/HDS 3.0 mg/kg Ideal Body Weight (IBW) and must begin treatment within 14 days being eligible. Melphalan/HDS treatment, patients will receive up to 6 treatments. Each treatment cycle consists of 6 weeks with an acceptable delay for another 2 weeks before the next planned treatment to allow for recovery of melphalan-related toxicity, if needed. Tumor response will be assessed every 12 weeks (+ 2 weeks) until disease progression. If the patient receives only 1 treatment, the disease assessment scans will be conducted 12 weeks after the date of the first treatment. The assessment scans will be reviewed by an Independent Review Committee (IRC), also referred to as Independent Central Review. At any time when progressive disease (PD) is observed, the patient will be removed from further study treatment and followed until death. Melphalan/HDS treatment will also be discontinued in the event that recovery from treatment related toxicity requires more than 8 weeks from last treatment. An end-of-treatment visit will be conducted approximately 6 to 8 weeks following the final study treatment. Ongoing treatment related adverse events (AEs) at the end-of-treatment visit will be followed until the severity is within one of the following parameters (1) Symptoms are resolved or return to baseline; (2) CTCAE Grade < 1 or can be explained; (3) patient death. The maximum possible duration of the study treatment for any patient will be 12 months. NOTE: Active Melphalan/HDS patients (currently in treatment) on PHP-OCM-301 will continue treatment on PHP-OCM-301A following the re-consenting process. NOTE: Patients on PHP-OCM-301 that have completed treatment and are entering or are already in the follow-up phase will be followed-up for survival and disease progression (as applicable) on PHP-OCM-301A following the re-consenting process. Follow-up Phase: Once the patient has completed the end-of-treatment (EOT) visit in accordance with the schedule of events they will enter the follow-up phase. If the disease has not progressed at the EOT (Section 6.2), the patient will need to continue with disease assessment visits every 12 weeks (+ 2 weeks) until disease progression is documented. If the disease has progressed before or at the EOT their follow-up is to be by phone every 3 months for survival status until death. Patients will be monitored, following the completion of study treatment, for the development of myelodysplasia and secondary leukemia. ;
