Myeloproliferative Syndromes: Clinical and Epidemiological: Advancing MPN Care: Innovative Therapies and Clinical Breakthroughs in Myelofibrosis Date: Monday, December 9, 2024 Time: 5:00 PM (Presentation) Location: Manchester Grand Hyatt San Diego, Harbor Ballroom DEFG Publication Number: 999 Title: A Phase Ib, Open-Label Study of Add-on Therapy with CK0804 in Participants with Myelofibrosis and Suboptimal Response to Ruxolitinib Submission ID: 211587 The study data to be presented demonstrates the safety and efficacy of CK0804 in patients with myelofibrosis who had previously failed standard treatments. Key findings from the trial include significant improvements in symptom burden, spleen volume reduction, blood transfusion dependence, and systemic inflammatory cytokine levels. Importantly, CK0804 was well-tolerated, with no significant drug-related adverse events observed, aside from one patient with a sulfa drug allergy who had an infusion reaction. Study Highlights Nine patients, with a median of two (range, 1-6) prior lines of treatment, were treated with CK0804. Improvements in fatigue and overall symptom burden were reported by all patients, with four out of six evaluable patients showing spleen volume reduction (SVR). Two patients who were transfusion-dependent showed a reduction in their monthly need for transfusions by the end of the treatment period. Longitudinal data indicates sustained benefits, including improvements in hemoglobin levels and inflammatory markers. Following the initial success of the Phase 1b trial, the Data Safety Monitoring Board has approved an expansion cohort to further explore the safety and efficacy of CK0804. This expansion includes an induction phase of four weekly doses, followed by five monthly doses, and active participant enrollment is ongoing (NCT05423691). About Myelofibrosis Myelofibrosis is a rare, chronic, and progressive blood cancer that causes scar tissue to form in the bone marrow, disrupting the production of normal blood cells. Patients with myelofibrosis often experience debilitating symptoms such as fatigue, spleen enlargement, and night sweats. Approximately 16,000 to 18,500 people in the U.S. are living with myelofibrosis, and those who fail to respond adequately to current treatments including ruxolitinib, face limited options and a poor prognosis. Inflammation is a key driver for disease pathogenesis and progression in myelofibrosis. About CK0804 CK0804 is an investigational, allogeneic, off-the-shelf Treg cell therapy that leverages the CXCR4/CXCL12 axis to suppress inflammatory cytokines implicated in myelofibrosis pathogenesis. CXCR4 enriched Tregs home faster to bone marrow compared to unmanipulated Tregs. Derived from clinical-grade umbilical cord blood and manufactured using Cellenkos' proprietary CRANE® process, CK0804 does not require HLA matching, making it an ideal therapeutic option for patients in need of prompt intervention. The therapy is administered intravenously and can be infused in an outpatient setting. About Cellenkos, Inc.

Treg Cell-based Therapies refer to therapeutic approaches that utilize regulatory T cells (Tregs) to modulate the immune system. Innovations in cell expansion and engineering techniques have greatly enhanced the ability to isolate, expand, and deliver functional Tregs. Ex vivo expansion technologies and genetic engineering (such as CAR-Tregs) have opened up new possibilities for enhancing the stability, specificity, and effectiveness of Treg therapies. LAS VEGAS, Oct. 28, 2024 /PRNewswire/ -- DelveInsight's ' Treg Cell-based Therapies Pipeline Insight 2024 ' report provides comprehensive global coverage of available, marketed, and pipeline Treg cell-based therapies in various stages of clinical development, major pharmaceutical companies are working to advance the pipeline space and future growth potential of the Treg cell-based therapies pipeline domain. Key Takeaways from the Treg Cell-based Therapies Pipeline Report DelveInsight's Treg cell-based therapies pipeline report depicts a robust space with 50+ active players working to develop 55+ pipeline therapies for various indications.

In September 2024, Abata Therapeutics announced that ABA-101, an autologous regulatory T-cell (Treg) therapy for the treatment of patients with progressive multiple sclerosis (MS), has received fast-track designation from the US FDA. In September 2024, PolTREG S.A. announced that China's National Intellectual Property Administration, PRC (CNIPA) had issued a notification to grant a patent for the intrathecal administration of the company's cellular therapies in patients with multiple sclerosis (MS). The intrathecal administration is an established method used to deliver therapy across the blood-brain barrier via injection into the subarachnoid space. In June 2024, Orca Bio announced that it had completed enrollment in the pivotal Precision-T Phase III clinical study. The primary endpoint of the Precision-T study is the rate of survival free from moderate-to-severe chronic graft versus host disease (GvHD). In March 2024, PolTREG announced that the company is planning to launch Phase II trials testing its Tregs therapy — the T-cell-based treatment PTG-007 in people with multiple sclerosis (MS). In February 2024, Cellenkos announced encouraging safety data from its innovative CK0803 neurotrophic T regulatory (Treg) cell therapy, being developed to help treat individuals with Amyotrophic Lateral Sclerosis (ALS).

Treg Cell-based Therapies Overview Treg cell-based therapies represent a promising frontier in immunotherapy, focusing on harnessing regulatory T cells (Tregs) to modulate the immune response in various clinical settings. Tregs play a crucial role in maintaining immune homeostasis and preventing autoimmune reactions by suppressing excessive immune responses. In the context of autoimmune diseases, these therapies aim to restore balance by expanding or enhancing Tregs to dampen inappropriate immune activity. For instance, in diseases like type 1 diabetes or multiple sclerosis, Treg cell-based treatments seek to prevent or slow disease progression by reestablishing immune tolerance. Beyond autoimmune disorders, Treg cell-based therapies are also being explored in cancer treatment. Tumors often exploit Tregs to evade immune detection, and by manipulating these cells, it's possible to enhance the anti-tumor immune response. Strategies include expanding Tregs ex vivo and reinfusing them to boost their numbers or modifying them to more effectively target tumor-associated antigens. These approaches hold the potential to improve the efficacy of existing immunotherapies and offer new avenues for treating cancers that are currently resistant to conventional treatments.
