Preclinical studies demonstrate that BPT958 induces potent, synergistic anti-tumor immune responses superior to PD-1 blockade alone, with activity in both PD-1-sensitive and PD-1-resistant tumor models.<\/p>\n<p>Here we introduce BPT958, a bifunctional PD1-IL2 immunoconjugate with an optimized and masked IL-2 payload, said Dr. Jon Wigginton, President of Research and Development at Bright Peak. &#8220;We rationally designed our tumor-activated IL-2 payload with the intent of selectively targeting antigen-experienced PD-1<sup>+<\/sup> T<sub>eff<\/sub> cells in the tumor microenvironment. We believe that this approach ultimately could yield a more favorable safety profile and increased therapeutic window compared to non-masked IL-2 approaches, and leverage the potential for use of BPT958 alone or in combination with other therapeutics for patients with a range of cancers.&#8221;<\/p>\n<p><strong>Details regarding the upcoming SITC abstract presentations are as follows:<\/strong><\/p>\n<p><strong>November 9, 2024, 9:00 AM  9:00 PM (EST)<\/strong><br \/><strong>Poster 1320: Identification of PD1-IL2<\/strong><sub><strong>TAP<\/strong><\/sub><strong>  a PD-1 Blocking Immunoconjugate Harboring a Tumor-Activatable Masked IL-2 Payload Lacking Binding to IL2R<\/strong><strong>\/CD122 <\/strong><\/p>\n<p><strong>Abstract Highlights <\/strong><\/p>\n<ul type=\"disc\">\n<li><strong>Using its chemical conjugation platform, Bright Peak generated a structurally unique <\/strong><strong><u>T<\/u><\/strong><strong>umor-<\/strong><strong><u>A<\/u><\/strong><strong>ctivated IL-2 <\/strong><strong><u>P<\/u><\/strong><strong>ayload (IL2<\/strong><sub><strong>TAP<\/strong><\/sub><strong>) masked by a protease-cleavable intramolecular loop preventing its binding to IL2Rb\/CD122.<\/strong><\/li>\n<li><strong>Site-specific chemical conjugation of the IL2<\/strong><sub><strong>TAP<\/strong><\/sub><strong> payload to an anti-PD-1 Ab generates the PD1-IL2<\/strong><sub><strong>TAP<\/strong><\/sub><strong> immunoconjugate (BPT958).<\/strong><\/li>\n<li><strong><em>In vitro<\/em><\/strong><strong>, masked BPT958 is inactive in the absence of PD-1 expression.
