Enhancing ICB Efficacy Through IL-1 Inhibition in TNBC

Официальное название

Rebooting Sensitivity to Checkpoint Blockade Therapy in Triple-Negative Breast Cancer With Isunakinra (RESETT- I)

Обзор

This study is a phase I/II open-label randomized clinical trial to examine whether administration of isunakinra (EBI-005), a modified recombinant IL1 receptor antagonist, can sensitize human TNBC to the PD1 inhibitor-pembrolizumab-based neoadjuvant chemotherapy (NAC/P) by changing the tumor microenvironment (TME) via reducing the recruitment of immunosuppressive tumorassociated macrophages (TAMs) and increasing activated cytotoxic T-lymphocytes (CTLs).

Подробное описание

Pre-clinical work has found that tumor cell IL-1β drives TAM recruitment, immunosuppression, and tumor progression in TNBC. In fact, experimental evidence, across most cancer types, supports a tumor-promoting role for IL-1β making IL-1β a target with clear therapeutic potential. Roles for IL-1β in growth, invasion and angiogenesis, metastases, stemness and epithelial-mesenchymal transition (EMT) and tumoral recruitment of TAMs and other pro-tumoral inflammatory cells have been extensively described, and IL-1β upregulation is generally associated with poorer prognosis. The best available clinical information suggests that targeting IL-1β reduces cachexia and remarkably is associated with a greater than 50% reduction of death from all cancers (phase 3 Cantos trial, testing the IL-1β inhibitor canakinumab (Ilaris®) to treat heart failure in a cohort of 10,061 patients). We are the first to suggest that TNBCs are the "perfect storm" for IL-1β production, with Notch providing IL-1β priming and the inflammasome ensuring cleavage, making TNBC an ideal candidate for IL-1β blockade. Supporting this, our most recent pre-clinical work shows that IL1β antagonists can synergize with ICB to eliminate TNBC.

This study is a phase I/II open-label randomized clinical trial evaluating the immunologic effects within the tumor, microenvironment, and host blood of patients treated with either: Group 1 Study participants randomized to Group 1 treatment group will receive isunakinra at a dose of 50mg SC daily x 24 weeks in addition to standard pembrolizumab-based neoadjuvant chemotherapy (NAC/P). Group 2 Study participants randomized to Group 2, the control group, will receive standard pembrolizumab-based neoadjuvant chemotherapy (NAC/P).

A total of 60 patients will be recruited across 3 institutions, randomized 1:1 to treatment (n=30) versus control (n=30).

The proposed study may provide important data regarding the mechanism of action, safety, feasibility and efficacy of isunakinra when added to NAC/P. It will inform sample size for a definitive phase 3 study designed to prove that isunakinra improves patient outcome.

• Препарат Group 1-Isunakinra
  isunakinra at a dose of 50mg SC daily x 24 weeks in addition to standard pembrolizumab-based neoadjuvant chemotherapy (NAC/P).

Первичные конечные точки

• Outcome-Study will test whether IL1 blockade can reduce TAM and sensitize human TNBCs to ICB. Outcome measure-changes in the TME induced by the addition of isunakinra to NAC/P will be determined. [Срок оценки: 6 years]
