Brief summary

The purpose of this trial is to assess whether treatment with NY-ESO-1 ISCOMATRIX® vaccine improves outcomes for people with Malignant Melanoma which has been removed, but is at high risk of relapse.

Detailed description

NY-ESO-1 protein is an immune target found in many cancers including melanoma. ISCOMATRIX® adjuvant enhances immune responses. This trial compares NY-ESO-1 ISCOMATRIX® vaccine with ISCOMATRIX® adjuvant alone to assess whether treatment with NY-ESO-1 ISCOMATRIX® vaccine improves outcomes for participants with Malignant Melanoma which has been removed, but is at high risk of recurrence. Eligible participants are randomly allocated to a treatment arm. Treatment involves four intramuscular (into a muscle) injections (1 injection every 4 weeks x 3, plus 1 injection at 6 months). Participants are assessed for recurrence of melanoma, safety and immune responses (by blood test) over the 18 month study period. Off study, their own doctor will follow them for melanoma recurrence and survival.

Interventions

BIOLOGICALNY-ESO-1 ISCOMATRIX®

100 μg of NY-ESO-1 protein formulated with 120 μg of ISCOMATRIX® adjuvant. Each patient will receive four intramuscular injections of NY-ESO-1 ISCOMATRIX® vaccine. The first three doses will be given at four-week intervals, days 1, 29, and 57, (± 3 days of scheduled date). The fourth injection will be given at month 6 (day 183 ± 3 days).

BIOLOGICALISCOMATRIX® adjuvant

120 μg of ISCOMATRIX® adjuvant Each patient will receive four intramuscular injections of ISCOMATRIX® adjuvant alone. The first three doses will be given at four-week intervals, days 1, 29, and 57, (± 3 days of scheduled date). The fourth injection will be given at month 6 (day 183 ± 3 days).

MeasureTime frameDescription
Rate of Relapse-free Survival at 18 Months18 monthsThe number of patients who were alive and relapse free 18 months after starting therapy and the number of patients who relapsed or died within 18 months of starting therapy. Disease was assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) as measured by CT. Disease progression or relapse was based on an increase of 20% or more in the sum of the longest diameter of target lesions, the appearance of any new lesion as confirmed by CT scan or death.

Overall Survival measured during the entire Period of Observation (up to 6years). Overall survival was measured from start of treatment to the last follow-up or death.

Time frame: through study completion; up to 6 years

Population: All randomized patients who received at least one dose of NY-ESO-1 ISCOMATRIX® vaccine or ISCOMATRIX® adjuvant.

Relapse-Free Survival During the Entire Period of Observation (up to 6 Years).

Disease was assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) as measured by CT. Disease progression or relapse was based on an increase of 20% or more in the sum of the longest diameter of target lesions, the appearance of any new lesion as confirmed by CT scan or death.

Time frame: through study completion; up to 6 years

Population: All patients who received at least one dose of NY-ESO-1 ISCOMATRIX® vaccine or ISCOMATRIX® adjuvant.
