CAR-DC for End-Stage IPF
8 participantsStarted 2026-02-01
Plain-language summary
Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fatal interstitial lung disease characterized by irreversible scarring, leading to respiratory failure. With limited treatment options and a poor prognosis, new therapies are urgently needed. This study investigates a novel cell therapy targeting pathological fibroblasts, a key driver of fibrosis.
Single-cell analyses identify CTHRC1+FAP+ fibroblasts as a collagen-producing subpopulation crucial in IPF progression. Chimeric antigen receptor (CAR) technology enables precise targeting of these cells. While CAR-Treg therapy has shown promise in preclinical models, its clinical translation requires careful safety evaluation regarding infection risk, potential tumor promotion, and immune reconstitution.
This trial employs an innovative approach using engineered dendritic cells (DCs). CAR technology is applied to generate immunosuppressive CAR-DCs (iCAR-DCs) designed to target FAP, localize to fibrotic lung areas, and attenuate fibrosis without eliciting a detrimental immune response. Preliminary mouse studies demonstrated that iCAR-DC administration following lung injury significantly reduced fibrosis without apparent organ toxicity and improved survival.
This single-arm trial aims to evaluate the efficacy and safety of this immunosuppressive CAR-DC therapy in patients with end-stage IPF. Key assessments will include changes in lung function, fibrosis extent on imaging, and comprehensive monitoring of potential adverse effects, particularly infections, tumor markers, and immune parameters.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. History of acute exacerbation of IPF within 4 weeks prior to screening or during the screening period.
. Presence of interstitial lung disease (ILD) other than IPF, including but not limited to: other forms of idiopathic interstitial pneumonia; ILD associated with fibrogenic agents, environmental exposures, or drug toxicity; other occupational lung diseases; granulomatous lung diseases; pulmonary vascular diseases; or ILD related to systemic diseases (e.g., vasculitis, infections such as tuberculosis, connective tissue diseases). Cases with uncertain diagnosis require serological testing and/or multidisciplinary team review for confirmation.
. Presence of significant active infection.
. History of malignancy, except for malignancies treated with curative intent and with no recurrence for ≥5 years, resected basal cell or squamous cell skin carcinoma, carcinoma in situ of the cervix, or resected colonic polyps.
. Significant history of infectious diseases.
. Presence of psychiatric illness or other conditions that would compromise the patient's ability to cooperate with study requirements, comply with treatment, or undergo monitoring.
. Known hypersensitivity to any component of the immunosuppressive CAR-DC cell product.
. History of severe renal failure requiring renal dialysis, or serum creatinine level \>2.5 mg/dL.
