Quinoline-3-carboxamide (Linomide) is a novel, synthetic immunomodulator acting via immunologic and non-immunologic mechanisms. It has shown efficacy against various malignancies, experimental autoimmune encephalomyelitis, and septic shock in animal models and has been investigated for clinical use in minimal residual myeloid leukemia with promising results. Interleukin-2 has shown considerable efficacy in palliative anti-tumor-treatment of advanced renal cell cancer, revealing remission rates of up to 40% in combination therapy regimens. Linomide is reported to exhibit synergistic effects with interleukin-2. Here we report on a clinical phase I/II study examining tolerance and efficacy of a combination therapy schedule of SQ interleukin-2 and PO Linomide in advanced renal cell cancer. Seventeen patients received 10 IU/m2 interleukin-2 per week for 8 weeks, resting interleukin-2 for another 8 weeks. In week 5 they started 5 mg Linomide daily, continued with 10 mg from week 7 to 16. No objective remissions were observed. Among 15 patients evaluable for response, 10 (66.7%) were progredient during the study. Three patients died during the observation period, including two not evaluable for response. Median survival was 4.0 months, median progression-free survival 2.5 months with a Kaplan-Meier estimate of 3.63 months. Fever, reduced general condition, nausea/vomiting, dyspnea, anorexia, chills and hypotension were the most common side effects, reaching WHO grade 3 in 6 and grade 4 in 2 cases. In summary, Linomide in combination with interleukin-2 provides no advantages in efficacy or toxicity over other therapy regimens employing interleukin-2.

Interleukin-2 (IL-2) is a cytokine intimately involved with both the function and regulation of the immune system. Genetic analysis of experimental autoimmune encephalomyelitis (EAE) provides strong evidence supporting the candidacy of IL-2 as a susceptibility gene. We investigated the association of two single nucleotide polymorphisms (SNPs) at position -384 in the promoter region and +114 in the first exon of the IL-2 gene through a case-control study involving 113 Japanese patients with multiple sclerosis (MS) and 118 healthy controls. Our results showed no significant differences in the distribution of the two polymorphisms between MS patients and controls. Furthermore, no association was observed between IL-2 gene polymorphisms and clinical characteristics, such as clinical course and age at disease onset. Together, our findings suggest that IL-2 gene polymorphisms do not influence the susceptibility to MS or the clinical characteristics of MS in Japanese patients.

Interleukin-2 (IL-2) has been shown to suppress immune pathologies by preferentially expanding regulatory T cells (Tregs). However, this therapy has been limited by off-target complications due to pathogenic cell expansion. Recent efforts have been focused on developing a more selective IL-2. It is well documented that certain anti-mouse IL-2 antibodies induce conformational changes that result in selective targeting of Tregs. We report the generation of a fully human anti-IL-2 antibody, F5111.2, that stabilizes IL-2 in a conformation that results in the preferential STAT5 phosphorylation of Tregs in vitro and selective expansion of Tregs in vivo. When complexed with human IL-2, F5111.2 induced remission of type 1 diabetes in the NOD mouse model, reduced disease severity in a model of experimental autoimmune encephalomyelitis and protected mice against xenogeneic graft-versus-host disease. These results suggest that IL-2-F5111.2 may provide an immunotherapy to treat autoimmune diseases and graft-versus-host disease.
