Innate Pharma

Innate Pharma said its first-half 2026 developments included closing a strategic partnership with Sobi for lacutamab, completing dose-escalation enrollment for IPH4502, and completing enrollment in the PACIFIC-9 phase III study of monalizumab. Chief Executive Officer Jonathan Dickinson said the Sobi transaction became effective on closing and included a $75 million upfront payment, which combined with a €30 million equity financing is expected to extend the company's projected cash runway through the end of the first quarter of 2028. The Sobi agreement also carries up to $40 million in near-term Sézary syndrome milestones, up to an additional $465 million tied to development-rights options and future regulatory and commercial milestones, and tiered double-digit royalties on future net sales. Innate has initiated the TELLOMAK-3 confirmatory phase III trial of lacutamab in cutaneous T-cell lymphoma, with the first patient expected in the first quarter of 2027, and plans to seek accelerated approval in Sézary syndrome in the second half of 2027. The company expects key clinical updates in the second half of 2026, including a PACIFIC-9 phase III readout for monalizumab and initial phase I data for IPH4502, an antibody-drug conjugate that has shown preliminary responses in several heavily pretreated solid-tumor populations.

Swedish Orphan Biovitrum AB and Innate Pharma SA announced that their previously announced strategic partnership is now effective following the expiration of applicable antitrust waiting periods and completion of other conditions. The partnership, entered on the 10th of August 2026, enables initiation of the TELLOMAK-3 confirmatory Phase 3 study in cutaneous T cell lymphoma, a key step toward filing for accelerated approval of lacutamab in Sézary syndrome, with the first patient expected in Q1 2027. Under the agreement, Innate will conduct the TELLOMAK-3 Phase 3 confirmatory trial to support a planned accelerated approval filing for Sézary syndrome, and the study will also support applications for full approvals in key jurisdictions in Sézary syndrome and mycosis fungoides. Sobi will receive exclusive global rights to commercialise lacutamab upon potential accelerated approval and will be eligible to assume full global development rights following positive Phase 3 results. Sobi will pay Innate Pharma USD 75 million upon the partnership becoming effective, and Innate will be eligible to receive up to a further USD 40 million in near-term development milestones connected to Sézary syndrome, up to USD 465 million related to the option for Sobi to get full development rights and to future regulatory and commercial milestones, plus tiered double-digit royalties on net sales.

Innate Pharma shares jumped more than 25% after the company announced a strategic partnership with Swedish Orphan Biovitrum AB to enable the TELLOMAK-3 confirmatory Phase 3 study of lacutamab in cutaneous T-cell lymphoma. Under the deal, Sobi will pay Innate $75 million upfront, with up to $40 million in near-term development milestones and up to $465 million tied to an option for full development rights and future regulatory and commercial milestones, plus tiered double-digit royalties on net sales. Innate said the upfront payment extends its projected cash runway through the third quarter of 2027. Separately, the company appointed Markus Jensen as Chief Medical Officer effective September 1, 2026, succeeding Sonia Quaratino.
