Abstract

Melanoma-associated retinopathy (MAR) is a rare autoimmune syndrome in patients with melanoma characterized by visual disorders. MAR is induced by the degeneration of bipolar cells of the retina and the presence of serum autoantibodies against retina proteins. Ipilimumab, an anti-cytotoxic T lymphocyte-associated antigen 4 antibody, improves survival in previously treated patients with metastatic melanoma, but is responsible for a spectrum of immune-related adverse events. Administration of ipilimumab to patients with autoimmune diseases (such as MAR or vitiligo) is actually not recommended. We report a patient presenting with MAR occurring during a melanoma relapse. Surgery and chemotherapy had no effect on visual acuity and melanoma increased. In the absence of alternative antitumoral treatment, we focused on the vital prognosis and treated the patient with ipilimumab. Two years after the treatment the patient is free from new metastasis but has presented with exacerbation of vitiligo and MAR. In the very rare case of melanoma with autoimmune disease without a therapy option, ipilimumab could be discussed, taking into account the fact that it can be effective on tumor burden but can also increase autoimmunity.

Improved survival with ipilimumab in patients with metastatic melanoma.

R Weber, Marie-Louise Vo Van, John Clark … (2010)

An improvement in overall survival among patients with metastatic melanoma has been an elusive goal. In this phase 3 study, ipilimumab--which blocks cytotoxic T-lymphocyte-associated antigen 4 to potentiate an antitumor T-cell response--administered with or without a glycoprotein 100 (gp100) peptide vaccine was compared with gp100 alone in patients with previously treated metastatic melanoma. A total of 676 HLA-A*0201-positive patients with unresectable stage III or IV melanoma, whose disease had progressed while they were receiving therapy for metastatic disease, were randomly assigned, in a 3:1:1 ratio, to receive ipilimumab plus gp100 (403 patients), ipilimumab alone (137), or gp100 alone (136). Ipilimumab, at a dose of 3 mg per kilogram of body weight, was administered with or without gp100 every 3 weeks for up to four treatments (induction). Eligible patients could receive reinduction therapy. The primary end point was overall survival. The median overall survival was 10.0 months among patients receiving ipilimumab plus gp100, as compared with 6.4 months among patients receiving gp100 alone (hazard ratio for death, 0.68; P<0.001). The median overall survival with ipilimumab alone was 10.1 months (hazard ratio for death in the comparison with gp100 alone, 0.66; P=0.003). No difference in overall survival was detected between the ipilimumab groups (hazard ratio with ipilimumab plus gp100, 1.04; P=0.76). Grade 3 or 4 immune-related adverse events occurred in 10 to 15% of patients treated with ipilimumab and in 3% treated with gp100 alone. There were 14 deaths related to the study drugs (2.1%), and 7 were associated with immune-related adverse events. Ipilimumab, with or without a gp100 peptide vaccine, as compared with gp100 alone, improved overall survival in patients with previously treated metastatic melanoma. Adverse events can be severe, long-lasting, or both, but most are reversible with appropriate treatment. (Funded by Medarex and Bristol-Myers Squibb; ClinicalTrials.gov number, NCT00094653.)

Autoimmunity correlates with tumor regression in patients with metastatic melanoma treated with anti-cytotoxic T-lymphocyte antigen-4.

Leah Haworth, Yuh-Shyong Yang, Suzanne Topalian … (2005)

Previously, we reported our experience treating 14 patients with metastatic melanoma using a fully human antibody to cytotoxic T-lymphocyte antigen-4 (anti-CTLA-4) in conjunction with peptide vaccination. We have now treated 56 patients to evaluate two different dose schedules of anti-CTLA-4 and to explore the relationship between autoimmunity and tumor regression. A total of 56 patients with progressive stage IV melanoma were enrolled onto the study. All had Karnofsky performance status > or = 60% with no prior history of autoimmunity. Twenty-nine patients received 3 mg/kg anti-CTLA-4 every 3 weeks, whereas 27 received 3 mg/kg as their initial dose with subsequent doses reduced to 1 mg/kg every 3 weeks. In both cohorts patients received concomitant vaccination with two modified HLA-A*0201-restricted peptides from the gp100 melanoma-associated antigen, gp100:209-217(210M) and gp100:280-288(288V). Two patients achieved a complete response (ongoing at 30 and 31 months, respectively) and five patients achieved a partial response (durations of 4, 6, 25+, 26+, and 34+ months, respectively), for an overall objective response rate of 13%. Tumor regression was seen in lung, liver, brain, lymph nodes, and subcutaneous sites. Of 14 patients with grade 3/4 autoimmune toxicity, five (36%) experienced a clinical response compared with only two responses in the 42 patients (5%) with no autoimmune toxicity (P = .008). There were no significant differences in response rate or toxicity between the two dose schedules. Administration of anti-CTLA-4 monoclonal antibody plus peptide vaccination can cause durable objective responses, which correlate with the induction of autoimmunity, in patients with metastatic melanoma.

Immunostimulatory monoclonal antibodies for cancer therapy.

Ignacio Melero, Drew M Pardoll, Lieping Chen … (2007)

Increasing immune responses with immunostimulatory monoclonal antibodies (mAbs) directed to immune-receptor molecules is a new and exciting strategy in cancer therapy. This expanding class of agents functions on crucial receptors, either antagonizing those that suppress immune responses or activating others that amplify immune responses. Complications such as autoimmunity and systemic inflammation are problematic side effects associated with these agents. However, promising synergy has been observed in preclinical models using combinations of immunostimulatory antibodies and other immunotherapy strategies or conventional cancer therapies. Importantly, mAbs of this type have now entered clinical trials with encouraging initial results.
