Inducing Systemic Immunity and Regressions in Metastatic Melanoma

Phase 1
Completed
Conditions
Metastatic Malignant Melanoma
Interventions
Biological: Autologous cytokines
Registration Number
NCT02350972
Lead Sponsor
NYU Langone Health
Brief Summary

In patients with multiple metastatic nodules of melanoma, the investigators evaluated whether autologous cytokines injected into cutaneous metastases would induce a systemic immune response as evidenced by the accumulation of dense lymphocytic infiltrates in metastases that had never been injected. Such immune responses were observed, and often the never-injected metastasis regressed completely. 20% of patients remained free of disease for greater than 5 years.

Detailed Description

Lymphocytic infiltrates were seen in never-injected nodules only after several weeks of injections elsewhere. No adverse events were seen. The tumor-infiltrating lymphocytes were able to kill autologous melanoma ex vivo. Some patients who experienced complete regressions of all metastases lived without disease for over 10 years.

Primary Outcome Measures
NameTimeMethod
Immune responses as evidenced by lymphocytic infiltrates in never-injected nodules.Cutaneous nodules were biopsied by a surgeon afer 8 to 20 weeks of injections.

The biopsies were examined by a licensed pathologist for the presence of dense lymphocytic infiltrates.

Secondary Outcome Measures
NameTimeMethod
Complete regression of a metastasisComplete regressions of all injected and never-injected metastases occurred in different pts after 13 weeks to 48 months of injections. Pts with progressive disease were switched to chemotherapy at any point in the study.

70 % of patients had at least one nodule regress. 40 % had all metastases completely regress for 5 to 20 years (median 60 months).
