T-Cell Prolymphocytic Leukemia

STAT3 Degrader KT-333 showed early signs of antitumor activity across liquid and solid tumors, including major responses in cutaneous T-cell lymphoma (CTCL) and Hodgkin’s lymphoma Robust STAT3 knockdown and positive immunomodulatory effect demonstrated in tumor as well as blood KT-333 was generally well-tolerated with dose escalation continuing WATERTOWN, Mass., Dec. 10, 2023 (GLOBE NEWSWIRE) -- Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing a new class of small molecule medicines using targeted protein degradation (TPD), today shared new data from its ongoing KT-333 Phase 1 trial. KT-333, a first-in-class, potent, highly selective, heterobifunctional small molecule degrader of STAT3, demonstrated early signs of antitumor activity at doses that were generally well-tolerated and associated with substantial STAT3 knockdown in blood and tumor. The data were presented at the American Society of Hematology (ASH) 65th Annual Meeting and Exposition taking place from December 9-12, 2023, in San Diego, California. “We’re encouraged by the data from the Phase 1 trial showing consistent fidelity of translation from preclinical models to patients, including STAT3 degradation in blood and tumor, induction of IFN-γ response signature, and antitumor responses in CTCL and Hodgkin’s lymphoma, which we believe supports the potential of KT-333 to address both hematological malignancies as a single agent and solid tumors as a potential novel combination partner with anti-PD-1 drugs,” said Jared Gollob, M.D., Chief Medical Officer, Kymera Therapeutics. “We look forward to completing the dose escalation portion of the Phase 1 study in 2024 and sharing additional updates on this first-in-class program across a range of indications at future medical meetings.” KT-333 STAT3 Clinical Update KT-333 degrades STAT3, a transcriptional regulator that has been linked to numerous cancers, as well as to inflammatory and autoimmune diseases, and is being developed for the treatment of STAT3-dependent hematological malignancies and solid tumors. The Phase 1 clinical trial is evaluating the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and clinical activity of KT-333 dosed weekly on 28-day cycles in adult patients with relapsed and/or refractory lymphomas, leukemias and solid tumors. The poster provides an interim update with a data cut-off as of October 18, 2023. Twenty-nine patients were treated across five dose levels (DL1-5) with a mean of eight doses, including five with cutaneous T-cell lymphoma (CTCL), two with large granular lymphocytic leukemia (LGL-L), one each with peripheral T-cell lymphoma (PTCL), B-cell and Hodgkins’s lymphoma, and nineteen with a variety of solid tumor malignancies. Dose escalation is ongoing at DL5 in solid tumor/lymphoma patients and at DL3 in leukemia patients. Dr. Aditi Shastri from Montefiore Medical Center and Albert Einstein College of Medicine, a lead investigator in the study, presented the interim Phase 1 findings. Highlights from the poster presentation include: A partial response (PR) was observed in one patient with Hodgkin’s lymphoma, and two PRs and one stable disease were reported among the five CTCL patients treated. Stable disease was observed in four patients with advanced solid tumors, including two head and neck cancer patients as well as patients with cholangiocarcinoma and renal cell cancer.KT-333 was generally well tolerated with primarily Grade 1 and 2 adverse events which included constipation, fatigue, nausea and anemia. The only KT-333 related adverse events that were Grade 3 or higher were stomatitis, arthralgia, and decreased weight in one patient each. Two dose-limiting toxicities (DLTs), stomatitis and arthralgia, occurred in LGL-L patients at DL5 and no DLTs were observed in solid tumor/lymphoma patients. Based on these findings, the study protocol was revised to continue dose escalation in solid tumor and lymphoma patients separately from patients with leukemia, including LGL-L and T-cell prolymphocytic leukemia (T-PLL) patients. The study continues to enroll solid tumor/lymphoma patients at DL5 and LGL-L/T-PLL patients at DL3.KT-333 achieved maximum degradation up to 96% in peripheral blood mononuclear cells at DL4-5 and with evidence of STAT3 pathway inhibition and downregulation of inflammatory biomarkers in peripheral blood.A critical cytokine involved in anti-tumor immunity, IFNγ, as well as IFNγ-stimulated genes, were induced in peripheral blood showing functional engagement of the JAK/STAT pathway, similar to preclinical studies.KT-333 resulted in substantial reduction of STAT3, pSTAT3 and SOCS3 in a CTCL patient tumor with concomitant induction of IFNγ-stimulated genes, suggestive of positive immunomodulatory response in the tumor microenvironment that both clinically and preclinically has been shown to enhance the activity of anti-PD-1 drugs, supporting potential expansion into combinations of KT-333 and anti-PD-1 agents. Preclinical data demonstrating the potential of STAT3 protein degraders as a therapeutic approach in venetoclax-resistant Acute Myeloid Leukemia was also presented at the meeting.

Data from 75 patients (44 with TDT, 31 with SCD) from the CLIMB-111, CLIMB-121 and CLIMB-131 studies with follow-up ranging from 1.2 to 37.2 months after exa-cel infusion continued to demonstrate that exa-cel has the potential to be a durable, one-time functional cure. All 31 patients with severe SCD, characterized by recurrent vaso-occlusive crises (VOCs), were free of VOCs after exa-cel infusion through the duration of follow-up, with follow-up ranging from 2.0 to 32.3 months. Of the 44 patients with TDT, 42 were transfusion-free with follow-up ranging from 1.2 to 37.2 months. Two patients who were not yet transfusion-free had 75% and 89% reductions in transfusion volume, respectively. The safety profile was generally consistent with myeloablative conditioning with busulfan and autologous stem cell transplant. The CLIMB-111 and CLIMB-121 trials are in Phase 3 and fully enrolled. CRISPR Therapeutics and Vertex have initiated two additional Phase 3 clinical trials, CLIMB-131 and CLIMB-141, for exa-cel in pediatric patients with TDT or SCD.CRISPR Therapeutics and Vertex have completed discussions with the European Medicines Agency (EMA) and the Medicines and Healthcare products Regulatory Agency (MHRA) on the submission package for exa-cel and are on track to submit for regulatory approvals of exa-cel for SCD and TDT in Europe and the U.K. by the end of 2022.

About exagamglogene autotemcel (exa-cel) Exa-cel, formerly known as CTX001™, is an investigational, autologous, ex vivo CRISPR/Cas9 gene-edited therapy that is being evaluated for patients with TDT or SCD characterized by recurrent VOCs, in which a patient’s own hematopoietic stem cells are edited to produce high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is the form of the oxygen-carrying hemoglobin that is naturally present during fetal development, which then switches to the adult form of hemoglobin after birth. The elevation of HbF by exa-cel has the potential to alleviate transfusion requirements for patients with TDT and reduce painful and debilitating sickle crises for patients with SCD. Earlier results from these ongoing trials were published in The New England Journal of Medicine in January of 2021. Based on progress in this program to date, exa-cel has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, Orphan Drug, and Rare Pediatric Disease designations from the FDA for both TDT and SCD. Exa-cel has also been granted Orphan Drug Designation from the European Commission, as well as Priority Medicines (PRIME) designation from the European Medicines Agency (EMA), for both TDT and SCD. Among gene-editing approaches being evaluated for TDT and SCD, exa-cel is the furthest advanced in clinical development. About CLIMB-111 and CLIMB-121The ongoing Phase 1/2/3 open-label trials, CLIMB-111 and CLIMB-121, are designed to assess the safety and efficacy of a single dose of exa-cel in patients ages 12 to 35 years with TDT or with SCD, characterized by recurrent VOCs, respectively.
