Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Melanoma, Ocular Combination Product: Melphalan/HDS Phase 3

Detailed Description:

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.

  1. Duration of Response (DOR) as determined by Independent Central Review Committee [ Time Frame: From time of 1st treatment until there is evidence of disease progression [assessed up to 36 months] ]
    Duration of Response (DOR) is defined as the time from first documented confirmed response of CR or PR based on RECIST v1.1 determined by the IRC to the first documented progression or death due to any cause.

  2. Disease Control Rate (DCR) determined by Independent Central Review Committee [ Time Frame: ORR will be assessed every 10-14 weeks from the start of 1st treatment and continues until the earlier of either when there is evidence of disease progression or 1 year from 1st treatment. ]
    DCR is defined as the proportion of patients with a best overall response of CR of any duration, PR of any duration, or stable disease (SD) for a minimum of 12 weeks from the eligibility date for PHP-OCM-301A patients (and randomization date for PHP-OCM-301 patients)

  3. Overall Survival [ Time Frame: From the start of the study to the date the patient was last known alive. [assessed up to 36 months] ]
    Overall Survival will be measured from the eligibility date for PHP-OCM-301A patients (and randomization date for PHP-OCM-301 patients) to the date of death (included all-cause mortality).

  4. Progression-Free Survival [ Time Frame: From start of study until disease progression. [assessed up to 36 months] ]
    PFS is defined as the time from the eligibility date for PHP-OCM-301A patients (and randomization date for PHP-OCM-301 patients) to the first occurrence of disease progression (either hepatic or extra-hepatic), as determined by the investigator and Independent Central Review Committee assessments using RECIST (version 1.1), or death from any cause.


Other Outcome Measures:
  1. Time to Objective Response (TOR) [ Time Frame: From study start through study completion. [Assessed up to 36 months] ]

    Hepatic PFS (hPFS) is defined as the time from the eligibility date for the PHP-OCM-301A patients (and randomization date for PHP-OCM-301 patients) to the first occurrence of hepatic disease progression, as determined by the Independent Central Review Committee (IRC) on imaging studies using RECIST 1.1 or death from any cause.

  4. Hepatic Objective Response Rate (hORR) as determined by Imaging Core Lab [ Time Frame: Assessed from the start of 1st treatment and continues until there is evidence of disease progression in the liver or 1 year from 1st treatment. [Assessed up to 36 months] ]
    Hepatic Objective Response Rate (hORR), is defined as the proportion of patients with tumor size reduction when evaluating hepatic lesions after study treatment as determined by the IRC using RECIST version 1.1.

  5. Quality of Life as Measured by Functional Hepatobiliary Symptom Index (FHSI-8) [ Time Frame: Quality of life will be assessed at screening and last week of each treatment and at end of treatment, which is the earlier of either disease progression or 6-8 weeks after the last treatment. [Assessed over 12 months] ]
    Using a questionnaire, patients will self-assess how they feel after the treatment. A total of eight questions are to be answered, patients are asked to complete each question based on the previous 7 days. Rating of answers are 0 (not at all) up to 4 (very much). Questions are (1). if the patient has lack of energy, (2) does the patient have nausea, (3) does the patient have pain, (4) does the patient feel they are losing weight, (5) does the patient have back pain, (6) is the patient tired, (7) is the patient bother by jaundice or yellow coloring of skin, (8)does the patient have pain/discomfort in the stomach area, The FHSI-8 quality of life instrument will be scored per standard methodology developed for the questionnaire. Results will be presented by treatment groups; changes from baseline will also be calculated.
