- CK0804 reduces symptom burden and induces spleen volume reduction in patients with myelofibrosis who have suboptimal response to prior lines of therapy
HOUSTON, Nov. 7, 2024 /PRNewswire/ -- Cellenkos® Inc., a clinical-stage biotechnology company focused on developing allogeneic, off-the-shelf, T regulatory (Treg) cell therapies for inflammatory disease areas of high unmet needs and autoimmune disorders, today announced that its CK0804 Phase 1b study data in myelofibrosis has been selected for oral presentation at the 66th Annual Meeting & Exposition of the American Society of Hematology (ASH), December 7-10, 2024, in San Diego, California.
The oral presentation will feature the safety and efficacy data from Cellenkos' Phase 1b trial evaluating CK0804 in patients with myelofibrosis who have suboptimal responses to prior therapies, including ruxolitinib. CK0804 is an off-the-shelf, allogeneic, non-HLA matched, CXCR4-enriched Treg cell therapy and is administered in fixed dose of 100 million cells infused every 28 days for 6 doses. CK0804 has shown early promise in addressing this high unmet medical need.

- Session Name: 634. 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.
Cellenkos is a clinical-stage biotechnology company based in Houston, Texas, focused on developing off-the-shelf Treg cell therapies for rare inflammatory diseases and autoimmune disorders. The company's portfolio includes four clinical-stage candidates:
- CK0801 for aplastic anemia: durable transfusion independence.
- CK0802 for COVID-19 ARDS: survival benefit
- CK0803 for amyotrophic lateral sclerosis (ALS): slowing of ALSFRSR score decline and decrease in neurofilament
- CK0804 for myelofibrosis: decrease in symptom burden and spleen volume reduction
Cellenkos' Treg therapies, derived from umbilical cord blood, are designed to provide powerful anti-inflammatory effects and long-lasting immune modulation without the need for donor matching. The company is committed to advancing the development of these promising therapies to improve the lives of patients with rare and underserved conditions.
