|Condition or disease||Intervention/treatment||Phase|
|Malignant Melanoma||Drug: Imiquimod Biological: NY-ESO-1 protein||Phase 1|
Patients applied imiquimod (250 mg) topically to a designated area of healthy skin on the upper inner arm or inner thigh (the cream remained on the skin overnight for 6-10 hours) every day for 5 consecutive days (i.e., for the first 5 days of Cycles 1-3 and for the first 4 days of Cycle 4). The NY-ESO-1 protein (100 μg) was injected intradermally into the imiquimod-pretreated area on Day 3 of each cycle for 4 consecutive 21-day cycles.
Safety was monitored continuously. Immunization was assessed by the generation of NY-ESO-1-specific cluster of differentiation (CD)4+ and CD8+ T cell responses in enzyme-linked immunosorbent spot (ELISPOT) assays and by the development or augmentation of NY-ESO-1-specific antibody titers, assessed by enzyme-linked immunosorbent assay (ELISA).
Blood samples were obtained for the assessment of clinical biochemistry and hematology, and physical examinations were performed at baseline, on Day 1 of each cycle, and at a follow-up visit at Week 13.
Skin biopsies of the vaccinated area were obtained 48 hours after the last injection (Day 5 of Cycle 4). To avoid irritation, imiquimod was not applied after the biopsies.

Experimental: Imiquimod + NY-ESO-1
Patients applied topical imiquimod followed by vaccination with intradermal injections of the NY-ESO-1 protein.
Patients applied imiquimod cream at bedtime every day for 5 consecutive days (for the first 5 days of Cycles 1-3 and for the first 4 days of Cycle 4) at a dose of 250 mg as supplied in single-use packets to a 4 x 5 cm area of healthy skin, alternating among the extremities (upper inner arms and inner thighs) in each cycle. The cream was to be rubbed into the skin until it was no longer visible. Patients were encouraged to wash their hands before and after applying cream. The application site was not occluded. The next morning, 6 to 10 hours after initial application, the treated area was washed with mild soap and water to remove any residual cream.
Other Name: Aldara
Biological: NY-ESO-1 protein
NY-ESO-1 protein was injected intradermally by a study physician or nurse at a dose of 100 μg into the imiquimod-pretreated area on Day 3 of each cycle for 4 consecutive 21-day cycles.
- Number of Patients With Treatment-emergent Adverse Events (TEAEs) [ Time Frame: Up to 4 months ]Toxicity was graded in accordance with the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 3.0, as follows: Grade 1 (mild), Grade 2 (moderate), Grade 3 (severe), Grade 4 (life-threatening), and Grade 5 (fatal). Adverse events (AEs) were reported based on clinical laboratory tests, vital sign and weight measurements, physical examinations, performance status evaluations, and any other medically indicated assessments, including patient interviews, from the time informed consent was signed through the last follow-up visit. AEs were considered to be treatment emergent (TEAE) if they occurred or worsened in severity after the first dose of study treatment.
- Number of Patients With Cellular Antibody Response to NY-ESO-1 at Two or More Post-vaccination Time Points [ Time Frame: Up to 4 months ]Assays to assess cluster of differentiation (CD)8+ and CD4+ antigen-specific responses were performed at baseline (Cycle 1 Day 1), throughout the vaccination period (Day 1 of Cycles 2 through 4 and Day 10 of each cycle), and at the 2 post-treatment follow-up visits (Weeks 13 and 16) by enzyme-linked immune absorbent spot (ELISPOT) assay following prior in vitro sensitization. A 3-fold increase in spot-forming cells over baseline defined a positive response. Suitable antigens may have included recombinant viral vectors encoding NY-ESO-1, or NY-ESO-1 overlapping peptides, depending upon availability.
- Number of Patients With Humoral Antibody Response to NY-ESO-1 [ Time Frame: Up to 4 months ]Assays to assess NY-ESO-1 specific antibodies were performed at baseline (Cycle 1 Day 1), throughout the vaccination period (Day 1 of Cycles 2 through 4 and Day 10 of each cycle), and at the 2 post-treatment follow-up visits (Weeks 13 and 16) by enzyme-linked immunosorbent assay (ELISA). Samples were diluted serially. The induction and augmentation of immunity were defined as an increase in antibody titer of ≥ 3× over buffer alone or ≥ 4× the pre-vaccination titer, respectively. Sera from the responding patients were tested a second time against a pool of NY-ESO-1 overlapping peptides to confirm NY-ESO-1 specificity; the number of patients in the table reflect the patients with confirmed NY-ESO-1 specificity.
