On June 12, 2025 Kura Oncology, Inc. (Nasdaq: KURA, "Kura") and Kyowa Kirin Co., Ltd. (TSE: 4151, "Kyowa Kirin") reported positive updated clinical data from KOMET-007, a Phase 1a/1b trial of ziftomenib, a highly selective oral investigational menin inhibitor, in combination with standards of care in patients with newly diagnosed NPM1-mutant (NPM1-m) and KMT2A-rearranged (KMT2A-r) acute myeloid leukemia (AML) (Press release, Kura Oncology, JUN 12, 2025, View Source [SID1234653844]). The data for the combination with cytarabine/daunorubicin (7+3) were presented as an oral presentation at the European Hematology Association (EHA) (Free EHA Whitepaper) 2025 Congress (EHA2025) being held in Milan, Italy from June 12-15, 2025.

"The findings presented at EHA (Free EHA Whitepaper)2025 underscore the potential of ziftomenib in combination with 7+3 as an early intervention in the frontline setting of AML and could offer a meaningful opportunity to improve patient outcomes," said Harry Erba, M.D., Ph.D., Director of the Leukemia Program at the Duke Cancer Institute. "The high rates of complete remission and MRD negativity across the 7+3 cohorts are particularly encouraging. The continued rapid enrollment in the Phase 1b portion of this study underscores the urgency and enthusiasm for further evaluating this combination approach."

"We remain very encouraged by the updated clinical activity, safety and tolerability data from the KOMET-007 study evaluating ziftomenib with 7+3 in newly diagnosed AML patients with NPM1 mutations or KMT2A rearrangements," said Mollie Leoni, M.D., Chief Medical Officer of Kura Oncology. "These updated data reinforce the combination potential of ziftomenib in the frontline setting, strengthening our confidence in its ability to provide a valuable treatment option for a significant portion of the AML population. We and our partners at Kyowa Kirin are working in earnest to prepare for the KOMET-017-IC and NIC pivotal Phase 3 studies, which will enable us to test ziftomenib-based combinations and their potential, if approved, to transform care for AML patients worldwide."

In the ongoing study, ziftomenib dosed once daily at 600 mg in combination with 7+3 continued to demonstrate robust and evolving clinical activity in patients with newly diagnosed AML. Among 71 response-evaluable patients, 92% (65/71) achieved a composite complete remission (CRc) (93% for NPM1-m, 89% for KMT2A-r patients) and 80% (57/71) achieved a complete remission (CR) (84% for NPM1-m, 74% for KMT2A-r patients) at the time of data cutoff. A rate of CR minimal residual disease (CR-MRD) negativity of 71% for NPM1-m with a median time to MRD negativity of 4.7 weeks and a rate of CR-MRD negativity of 88% for KMT2A-r patients with a median time to MRD negativity of 4.4 weeks were observed. Ziftomenib did not delay time to neutrophil and platelet count recovery, which was comparable to intensive chemotherapy regimens.

Median follow-up times for the two populations were 24.9 weeks (range 4.3-47.1) in NPM1-m patients and 15.7 weeks (range 1.1-40.3) in KMT2A-r patients. Among response-evaluable NPM1-m patients, neither a median duration of CR nor a median overall survival (OS) had been reached. Among response-evaluable KMT2A-r patients, a median duration of CR was determined to be 25.6 weeks (95% CI, range 8.3-NE), and a median OS had not been reached. Notably, 96% (47/49) of NPM1-m patients and 88% (29/33) of KMT2A-r patients remained alive and on study.

The safety population included 82 newly diagnosed adult patients with NPM1-m or KMT2A-r AML from the pooled Phase 1a/1b portions of the trial at the 600 mg QD dose of ziftomenib. The safety profile observed with ziftomenib was consistent with previously reported data. Ziftomenib-related adverse events (TRAEs) of ≥ Grade 3 (Gr3), which occurred in more than 10% of patients were febrile neutropenia (15%), decreased platelet count (15%), anemia (11%) and decreased neutrophil count (11%). One case of differentiation syndrome (KMT2A-r, Gr3) was successfully managed by protocol-specified mitigation strategies. Two cases of investigator-assessed QTc prolongation (both KMT2A-r, Gr3) were reported; both patients were on other medications (posaconazole and/or piperacillin/tazobactam), which have been identified as potentially causing QT prolongation at the time of QT assessment. No dose-limiting toxicities, drug-drug interactions, clinically meaningful ziftomenib-associated QTc prolongation or additive myelosuppression were observed.

"Despite the availability of approved therapies for AML, up to 70% of patients who initially achieve a complete response relapse within three years – highlighting a substantial unmet need," said Takeyoshi Yamashita, Ph.D., Executive Vice President and Chief Medical Officer of Kyowa Kirin. "The data presented at EHA (Free EHA Whitepaper)2025 suggest a favorable safety, tolerability, and efficacy profile for ziftomenib. We are encouraged by its potential as a future first-line treatment option and are committed to advancing the KOMET-017 Phase 3 trial, expected to begin later this year, to further evaluate its value in AML care."

The EHA (Free EHA Whitepaper)2025 oral presentation highlighting ziftomenib combined with 7+3 in newly diagnosed (1L) NPM1-m and KMT2A-r AML, and an encore presentation of results from the KOMET-001 registrational trial of ziftomenib in relapsed/refractory (R/R) NPM1-m AML (also presented during EHA (Free EHA Whitepaper)2025) are available in the Posters and Presentations section of the Kura website. The KOMET-017 protocol consists of 2 separate Phase 3 studies, which will investigate the benefits and risks of adding ziftomenib to standards of care treatments in patients newly diagnosed NPM1-m or KMT2A-r AML and which is registered at www.clinicaltrials.gov as NCT07007312.

Virtual Investor Event

Kura will host a virtual investor event featuring company management and investigators from the KOMET-007 trial of ziftomenib in combination with 7+3 in patients with NPM1-m and KMT2A-r AML at 4:30pm ET / 1:30pm PT on Wednesday, June 18, 2025. Those who would like to participate may access the live webcast here, or register in advance for the teleconference here.

Golidocitinib Shows Potential to Significantly Improve Patient Outcomes in PTCL

PTCL patients who achieved tumor response with first-line standard therapy will relapse. Approximately 40% of patients with complete response and 80% with partial response experienced disease progression within 2 years after initial tumor response, and the prognosis of these relapsed patients was very poor.

The 24-month follow-up results from JACKPOT26, a prospective, multicenter Phase 2 clinical study of golidocitinib will be unveiled at EHA (Free EHA Whitepaper) and featured as an oral presentation at ICML. The data suggest that golidocitinib showed promising efficacy in maintaining and enhancing tumor response with an acceptable and manageable safety profile in patients with PTCLs post first-line therapies.

In Cohort 1 (patients with complete response), the 24-month disease-free survival (DFS) rate reached 74.2%, with consistent efficacy observed across different subtypes.
In Cohort 2 (patients with partial response), the complete response rate (CRR) was 50.0%, the median duration of response (DoR) was 23.9 months, and the median progression-free survival (PFS) was 17.4 months, with the longest PFS reaching 35.9 months and the patient was still responding.
"Golidocitinib, a next-generation oral and highly selective JAK1 inhibitor, addresses a critical unmet need for effective maintenance therapy following first-line treatment in PTCL," said Professor Jie Jin, lead principal investigator of the JACKPOT26 study at the First Affiliated Hospital of Zhejiang University School of Medicine. "Its unique mechanism of action not only delivers strong anti-tumor activity—allowing 50% of patients with partial remission (PR) to achieve complete remission (CR)—but also modulates the tumor immune microenvironment through its anti-inflammatory and immunomodulatory effects. These unique features help delay relapse and extend survival, positioning golidocitinib as a highly promising option for maintenance therapy in PTCL."

In addition, golidocitinib has shown encouraging antitumor activities and favorable safety profiles in combination with CHOP in 1st line PTCL patients, as well as in rare T-cell lymphoma subtypes, including relapsed/refractory T-cell large granular lymphocytic leukemia (r/r T-LGLL) and monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL). Further studies are warranted to validate the results.

DZD8586 Overcomes Multi-Drug Resistance in CLL and other B-NHL

A pooled analysis of two phase I/II studies of DZD8586 in CLL/SLL patients previously treated with covalent/non-covalent Bruton’s Tyrosine Kinase (BTK) inhibitors and BTK degraders was presented in an oral session at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and will be presented at EHA (Free EHA Whitepaper). Subgroup analyses will be presented as an oral presentation at ICML.

In heavily pretreated CLL/SLL, DZD8586 achieved an ORR of 84.2%. Tumor response with a manageable safety profile was observed irrespective of prior covalent/non-covalent BTKi, BTK degrader, or BCL-2 inhibitor treatment, and in patients with classic BTK resistance mutations (C481X) as well as other BTK mutations, including kinase-dead mutations. No drug-related bleeding, atrial fibrillation, or major cardiac events observed.

A Phase II study of DZD8586 monotherapy in relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL) will also be presented at EHA (Free EHA Whitepaper) and ICML. Clinical activities from small molecule targeted drugs such as BTK inhibitors have been less than desired for the treatment of DLBCL. Compensatory or redundant pathway activation could be one of the main escape mechanisms. DZD8586, a novel LYN/BTK dual inhibitor, is designed to overcome these limitations by blocking both BTK and LYN signaling pathways, and thus potentially improve therapeutic outcomes.

At recommended phase 2 doses (RP2Ds) of 50 mg and 75 mg QD, DZD8586 monotherapy demonstrated promising anti-tumor activity in r/r DLBCL. The majority of patients showed target lesion shrinkage, with a CRR of 35.5%. Complete responders showed durable responses, with 81.8% of patients remaining in response and the median DoR was not reached. Notably, it showed efficacy in both GCB and non-GCB subtypes, supporting its broad therapeutic potential.

Dr. Xiaolin Zhang, CEO of Dizal, remarked, "We are excited that golidocitinib and DZD8586 have demonstrated promising potential in PTCL and B-cell non-Hodgkin lymphoma (B-NHL), two areas with substantial unmet clinical needs. The selection of multiple studies for oral presentations at global leading conferences represents a strong recognition of our capabilities in research and development and further affirms our commitment to bringing transformative therapies to patients worldwide."

About golidocitinib (DZD4205)
Golidocitinib is currently the first and only Janus kinase 1 (JAK1) selective inhibitor being evaluated for the treatment of r/r PTCL. In June 2024, golidocitinib was approved by the National Medical Products Administration (NMPA) of China for the treatment of adult patients with relapsed or refractory peripheral T-cell lymphoma (r/r PTCL).

At the data cut-off date of August 31, 2023, golidocitinib has demonstrated robust and durable anti-tumor efficacy, with an ORR of 44.3%. All subtypes benefited well, and the ORR of common subtypes exceeded 40%. More than 50% of the patients with tumor remission achieved a complete response with a CRR of 23.9%. Per IRC assessment, the median duration of response (mDoR) reached 20.7 months. As of February 2024, golidocitinib showed a median overall survival (mOS) of 24.3 months.

Golidocitinib was granted Fast Track Designation by the U.S. FDA for the treatment of r/r PTCL in February 2022. In September 2023, the CDE accepted its NDA and granted Priority Review for the treatment of r/r PTCL. The Phase I clinical data of golidocitinib (JACKPOT8 PART A) were published in Annals of Oncology (Impact Factor: 51.8), and global pivotal trial data of golidocitinib for the treatment of r/r PTCL (JACKPOT PART B) were published in The Lancet Oncology (Impact Factor: 54.4).

About DZD8586
DZD8586 is a first-in-class, non-covalent, LYN/BTK dual inhibitor with full blood-brain barrier (BBB) penetration, designed as a potential treatment option for B-cell non-Hodgkin lymphoma (B-NHL).

While Bruton’s Tyrosine Kinase (BTK) inhibitors have been approved for the treatment of B-NHL, resistance can arise through two major mechanisms: the BTK C481X mutation and BTK-independent BCR signaling pathway activation. Currently, there is no targeted therapy available to address both resistance mechanisms, posing an urgent clinical challenge. Although BTK degraders have shown encouraging efficacy in early clinical studies, mutation-related resistance has been reported, and degrader-related toxicities may affect long-term clinical application.

DZD8586 has high selectivity against other TEC family kinases (TEC, ITK, TXK and BMX). By targeting BTK and LYN, it blocks both BTK-dependent and -independent BCR-signaling pathways, effectively inhibiting tumor growth of B-NHLs in cell lines and in animal models. Phase I clinical trial suggests that DZD8586 exhibits favorable PK properties, good central nervous system (CNS) permeability, complete blockade of BCR signaling, and encouraging anti-tumor efficacy with good safety and tolerability in patients with B-NHL.

On June 12, 2025 Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of targeted protein degradation medicines, reported positive clinical data from the Company’s ongoing NX-5948-301 study, a Phase 1a/b clinical trial of bexobrutideg (NX-5948) in patients with relapsed or refractory B-cell malignancies (Press release, Nurix Therapeutics, JUN 12, 2025, View Source [SID1234653846]).

The data include findings from the fully enrolled Phase 1a dose escalation study in patients with relapsed/refractory chronic lymphocytic leukemia (CLL) and the ongoing Phase 1a/1b cohorts of patients with Waldenström macroglobulinemia (WM). Talha Munir, M.B. Ch.B, Ph.D., consultant hematologist at Leeds Teaching Hospitals NHS Trust, deputy chair of the United Kingdom National Cancer Research Institute CLL Study Group, and Dima El-Sharkawi, M.B., B.S., M.A., Ph.D., MRCP FRCPath, Consultant Haematologist, Royal Marsden NHS Foundation Trust, Sutton, U.K., will present these data at the 30th European Hematology Association (EHA) (Free EHA Whitepaper) Congress (EHA2025), taking place June 12–15, 2025, in Milan, Italy.

"These data demonstrate an impressive safety and efficacy profile for bexobrutideg with improvement in responses in patients over time, including the notable achievement of a complete response in a patient with CLL and a history of two lines of prior therapy who has been on bexobrutideg treatment for over two years," said Dr. Munir. "Patients with relapsed or refractory CLL and WM who have failed treatments with commonly prescribed BTK inhibitors and other agents due to intolerance or acquired resistance have few therapeutic options. Nurix’s bexobrutideg has the potential to address this unmet need and provide a life-changing treatment for patients with CLL and WM."

"With longer time on treatment, we are encouraged by the continued favorable safety profile and high ORR with deepening responses in CLL and WM, including those with clinical and genomic high risk features including CNS involvement," said Paula G. O’Connor, M.D., chief medical officer of Nurix. "We have further expanded our Phase 1b cohorts in select CLL populations and remain on track to initiate pivotal studies in 2025."

"Bexobrutideg offers a next-generation approach to BTK targeting with exquisite selectivity, superior preclinical potency, broad coverage of mutations and demonstrated clinical activity in areas of high unmet medical need," said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. "We are not only preparing to initiate pivotal studies in the coming months but are also laying the foundation for the commercialization of bexobrutideg as a differentiated treatment option for patients with B-cell malignancies."

Data presented at EHA (Free EHA Whitepaper)2025 include efficacy and safety findings for patients with CLL/SLL in the fully enrolled Phase 1a dose escalation study (n=48). This cohort of CLL patients was a heavily pretreated population that had received a median of four prior lines of therapy (range = 2–12) including prior covalent BTK inhibitors (97.9%), prior BCL2 inhibitors (83.3%), and prior non-covalent BTK inhibitors (27.1%). At baseline, many patients had mutations associated with BTK inhibitor resistance, including mutations in BTK (38.3%) and PLC2G (14.9%). Poor prognostic features were common, including TP53 mutations (44.7%), and five patients (10.4%) had central nervous system (CNS) involvement.

Patients were treated with bexobrutideg at doses ranging from 50 mg to 600 mg once daily by oral administration in the Phase 1a dose escalation study. As of the March 12, 2025 data cut, the median follow up was 9.0 months with most patients still on treatment. Bexobrutideg was well tolerated across all doses evaluated with the most common treatment emergent adverse events of purpura/contusion (45.8%), neutropenia (29.2%) and thrombocytopenia (22.9%), primarily low grade. No new onset atrial fibrillation was observed. Among the efficacy evaluable patients with CLL (n = 47), bexobrutideg treatment resulted in a robust objective response rate (ORR) of 80.9% across all doses tested with a median time to first response of 1.9 months. Many patients experienced deepening of their response with longer time, with multiple conversions from stable disease to partial responses and one patient, who has been on treatment for over two years, experienced a complete response. The median duration of response has not been reached, with 18 patients on treatment for more than a year. Responses were observed across all populations regardless of prior treatment, baseline mutations, or CNS involvement.

The data presented at EHA (Free EHA Whitepaper) included patients with WM (n=22) treated with bexobrutideg at doses ranging from 50 mg to 600 mg once daily by oral administration from both the Phase 1a dose escalation and Phase 1b cohort expansion. Among the 22 WM patients, the median age was 72.5 years (range 58-86 years) and the median number of prior lines of therapy was 3 (range 2-5). All 22 patients previously had been treated with a covalent BTK inhibitor (100%), 21 had received prior chemotherapy/chemo-immunotherapy (95.5%), four had received prior non-covalent BTK inhibitor (18.2%), and one patient (4.5%) had received prior treatment with a BCL2 inhibitor. Baseline mutation status in MYD88 and CXCR4 was captured from patient records. 15 patients (68.2%) had mutations in MYD88, and five patients (22.7%) had mutations in CXCR4. Bexobrutideg was well tolerated in patients with WM with a profile that was consistent with the overall study population and previous disclosures. Adverse events (AEs) were predominantly low grade; with the most common being petechiae (27.3%), diarrhea (22.7%), purpura/contusion (18.2%), neutropenia (18.2%), and thrombocytopenia (18.2%). There were no dose limiting toxicities observed and no grade 5 AEs. Two treatment emergent AEs led to drug discontinuation. No new onset atrial fibrillation was observed.​ As of the March 12, 2025 data cut, 19 patients were evaluable for responses. Objective response was observed in 16 patients (84.2%), including two patients (10.5%) with very good partial response (VGPR), 11 patients (57.9%) with partial response (PR), and three patients (15.8%) with minor response (MR). Three patients (15.9%) had a best response of stable disease (SD). Responses were observed in patients regardless of their baseline mutations in MYD88 and CXCR4. Steady reductions in IgM levels were observed starting from the first assessment at four weeks, which continued to deepen, and three patients achieved IgM reductions of greater than 90%.
