Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 65 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age ≥ 18 years.
  • Diagnosis of probable or proven fungal infection according to EORTC criteria20, who have been treated with the best available antifungal strategy and present at least one of the following criteria indicating inadequate response to antifungal therapy: Increase in fungal infection biomarker levels (serum or bronchoalveolar lavage galactomannan, or serum β-D-glucan) after at least one week of antifungal therapy:
  • Persistence of positive cultures despite having received ≥2 weeks of appropriate antifungal treatment.
  • Radiological worsening of lesions suggestive of fungal infection despite having received ≥2 weeks of appropriate antifungal treatment, and when at least 2 weeks have passed since the previous imaging study.
  • Clinical deterioration and microbiological isolation of a fungus resistant to all available antifungal treatments (including cases in which a specific antifungal cannot be administered due to the risk of unacceptable toxicity).
  • Rapidly progressive clinical deterioration despite the implementation of all available antifungal measures, conferring a poor prognosis for the patient.
  • Signing the informed consent form to participate in the clinical trial and to receive CD5CAR-CBNK therapy. If the patient is not in a condition to sign the informed consent form, consent will be requested from the family and patient consent for the study continuation will be obtained as soon as deemed possible.

Who cannot join

  • An expected survival of less than four weeks due to a cause unrelated to the current fungal infection.
  • Patients with positive HIV serology.
  • Pregnant or breastfeeding women.
  • Men or women of childbearing potential unable or unwilling to use highly efficient contraceptive measures from the beginning until the end of the study.

CD5CAR-NK is a first-in-human, pilot, dose-escalation, and single-site study to evaluate the safety of CD5CAR-CBNK in patients with invasive mold diseases (IMD).

The study population consists of patients aged ≥18 years with refractory mold infections.

The number of patients treated will be 10.

This is a dose-escalation study including 3 cohorts. The dose escalation scheme will follow the following scheme:

Cohort 1(3 patients) The sentinel patient of cohort 1 will receive 10 x106 CAR+ cells of CD5CAR-CBNK at day 0. Intra-patient safety will be reviewed daily following the first dose. The second dose (day+3) and third (day+6) will only be administered after a safety review from clinicians that confirms the absence of dose-limiting toxicities (DLTs).

Cohort 1 is planned to include 3 evaluable patients. If a patient does not receive the full planned dosing schedule (all 3 doses), additional patients will be enrolled until at least 3 patients have completed the full prescribed treatment for this cohort. Escalation to Cohort 2 will only occur once safety data from 3 fully-treated patients have been reviewed.

The first subject in each cohort will be dosed and undergo a safety observation period between administrations. The second subject will be dosed 7 days after the first subject completes treatment and after review of safety data. The third subject will be dosed 3 days after the last dose of the second subject, subject to confirmation of acceptable safety.

Cohort 2 (3 patients) The sentinel patient of cohort 2 will receive 10 x106 CAR+ cells of CD5CAR-CBNK at days 0,3 and 6 followed by 25 x106 CAR+ cells at days 9 and 12. Intra-patient safety will be reviewed daily following the first 25 million dose. The dose at day +12 will only be administered after a safety review from clinicians that confirms the absence of dose-limiting toxicities (DLTs).

Cohort 3 (4 patients) The sentinel patient of cohort 3 will receive 10 x106 CAR+ cells of CD5CAR-CBNK at days 0,3 and 6 followed by 25 x106 CAR+ cells at days 9 and 12, and additionally 50 x106 CAR+ cells at days 15 and 18. In this occasion, intra-patient safety will be reviewed daily following the first 50 million dose. The dose at day +18 will only be administered after a safety review from clinicians that confirms the absence of dose-limiting toxicities (DLTs).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CD5CAR-CBNK in people with Fungal Infection, run by Fundacion Clinic per a la Recerca Biomédica at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 6 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Carolina Garcia Vidal, Dr. (+34932775400, cgarciav@clinic.cat), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluate the safety of allogeneic CD5CAR-CBNK cells in patients with refractory mold infection. (time frame: 28 days following the first infusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2026.
