On June 26, 2026, Curis announced that eleven clinical sites had opened for enrollment in the TakeAim CLL study. Today, Curis is announcing that it has consented the first six patients in that study – and reaffirmed its guidance for the dosing of five CLL patients by the end of July 2026, with initial CLL data expected in December 2026.

"We are encouraged by the strong interest among clinical sites and key opinion leaders in our TakeAim CLL study that has enabled us to exceed expectations for site activation and enrollment," said James Dentzer, Chief Executive Officer of Curis. "It reflects the clear unmet need in CLL and the excitement for the potential of emavusertib to fundamentally change the treatment paradigm in CLL."

In CLL, disease is driven by NF-kB dysregulation, which is in turn driven by two biologic pathways: BCR and TLR1. The goal of combining emavusertib with a BTK inhibitor (BTKi) in the TakeAim CLL Study is to enable a dual blockade of NF-kB, by inhibiting both the BCR and TLR pathways. BTK inhibitors (BTKi) block the BCR pathway; emavusertib blocks the TLR pathway.

BTKi is the current standard of care in CLL. In the registrational study for the BTKi zanubrutinib, 93% of patients were able to achieve an objective response, but only 7% achieved complete response2. More recent clinical studies have demonstrated that adding emavusertib to a BTKi regimen, blocking both the TLR and BCR pathways, can enable patients with NHL to achieve deeper responses, including complete responses or undetectable minimal residual disease (MRD).
