Can a light therapy clean cancer cells from blood? new trial aims to find out
NCT ID NCT05157581
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial is testing whether a procedure called extracorporeal photopheresis (ECP) can reduce tumor cells in people with Sezary syndrome, a rare blood cancer that affects the skin. Twenty participants will receive ECP weekly for a month, then every two weeks for five months. Researchers will analyze blood samples to see how the immune system responds and whether cancer cells decrease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Extracorporeal photopheresis (ECP) with methoxsalen
- What this could lead to
- If successful, this could show that ECP effectively reduces cancer cells in the blood and skin for people with Sezary syndrome, offering a treatment option.
- What could go wrong
- This is a small, early-phase trial with only 20 participants, so results may not apply to everyone. ECP is a complex procedure and may not work for all patients.

Inclusion Criteria: 1. Patient with an established diagnosis of Sezary syndrome (stage IVA1) 2. Patients amenable for ECP 3. The patient must have a minimum wash-out period of 3 weeks between the last dose of prior systemic therapy 4. Patients should have recovered from all adverse events related to prior therapy to ≤ grade 1 5. Signed informed consent form prior to any protocol-specific procedures. Exclusion Criteria: 1. Visceral metastasis of lymphoma 2. Concomitant administration of radiotherapy or systemic anti-cancer therapy including but not restricted to: chemotherapy, biological agents, or immunotherapy 3. Patients with known NCI CTCAE grade 3 or higher active systemic or cutaneous viral, bacterial, or fungal infection. 4. Patients with any serious underlying medical condition that would impair their ability to receive or tolerate the planned treatment and/or comply with study protocol. 5. Patients with dementia or altered mental status that would preclude understanding and rendering of informed consent document. 6. Patients with known allergy to Methoxsalen or heparin (as part of SOC ECP procedure). 7. Patients who are pregnant. -
