New drug cocktail aims to tame rare nerve and blood disorder
NCT ID NCT07652879
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests a combination of three drugs—carfilzomib, cyclophosphamide, and dexamethasone—in 20 people newly diagnosed with POEMS syndrome, a rare disorder affecting nerves and blood. The goal is to see if the regimen can reduce abnormal proteins and improve symptoms. Participants will receive the drugs intravenously on specific days over several cycles.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- carfilzomib, cyclophosphamide, and dexamethasone (KCD regimen)
- What this could lead to
- If successful, this could provide a new treatment option to control POEMS syndrome and improve nerve function.
- What could go wrong
- This is a small, early-phase trial with only 20 people, so results may not apply broadly. Side effects include infections, blood issues, and nerve worsening.

Inclusion Criteria: 1. Newly diagnosed POEMS syndrome meeting the Dispenzieri diagnostic criteria (2023 version); 2. Age 18-75 years; 3. ECOG performance status 0-3, with an estimated life expectancy \>3 months; 4. No active infective diseases; 5. No prior anti-POEMS therapy except for corticosteroids; 6. No severe organic impairment of major organs, meeting the following laboratory requirements: creatinine clearance ≥40 mL/min, total bilirubin ≤1.5 × upper limit of normal (ULN); AST and ALT ≤2.5 × ULN; cardiac enzymes \<2 × ULN; left ventricular ejection fraction within normal range on echocardiography, and no clinically significant electrocardiogram abnormalities; 7. Absolute neutrophil count ≥1.5 × 10\^9/L without prior growth factor support; platelet count ≥50 × 10\^9/L without platelet transfusion within 7 days prior to screening; hemoglobin ≥60 g/L; 8.

HIV positivity, or active hepatitis A, hepatitis B, or hepatitis C infection; or hepatitis B virus DNA \>10\^2 copies/mL; 3. Concurrent severe unstable medical conditions, including heart failure, renal failure, liver failure, bleeding disorders, arterial/venous thrombotic events within 6 months, uncontrolled diabetes mellitus, or a history of active hemorrhagic cystitis; 4. History of autoimmune diseases (e.g., Crohn's disease, rheumatoid arthritis, systemic lupus erythematosus) within the past 2 years that caused end-organ damage or required systemic immunosuppressive or disease-modifying therapy; 5. Severe active infections (e.g., untreated tuberculosis, pulmonary aspergillosis); 6. Presence of other malignancies (except non-melanoma skin cancer, in situ cervical, bladder, or breast cancer with disease-free survival \>5 years); 7. Epilepsy requiring medication, dementia, or other mental status abnormalities that interfere with understanding or complying with the study protocol; 8.
