New drug trial aims to rescue failing lungs after transplant
NCT ID NCT07538336
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a one-time infusion of emapalumab in 40 adults who had a lung transplant and now have a sudden drop in lung function (acute lung allograft dysfunction). The goal is to see if the drug can help their lungs recover to near-normal function within 90 days. Emapalumab blocks a protein that may be causing the damage.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- emapalumab
- What this could lead to
- If it works, this could point toward a treatment for sudden lung function decline after lung transplant, helping patients breathe better without needing a new transplant.
- What could go wrong
- This is a small, early-phase trial with only 40 people. The drug may not improve lung function, and there are risks like serious infections since emapalumab suppresses the immune system.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Recipients ≥10 months post-lung transplant who are enrolled in existing biorepository study (IRB #13-10738) will be approached if they have ALAD and elevated AI2 and CXCL9 levels * Age: ≥18 years old * Informed Consent: Ability to provide written informed consent to participate in the study. Exclusion Criteria: * Active Bacterial Infection: Positive bacterial cultures from bronchoalveolar lavage (BAL) samples at the time of ALAD diagnosis. Viral infections, which are typically treated in lung transplant recipients with a steroid taper and cleared by type I interferons, are not exclusion criteria per se. * Active CMV or EBV Infection: Active reactivation of cytomegalovirus (CMV) or Epstein-Barr virus (EBV) based on plasma PCR testing. * Severe Comorbidities: Presence of severe conditions likely to compromise study participation or outcomes (e.g., terminal illness). * Pregnancy or Breastfeeding: Women who are pregnant or breastfeeding at the time of screening. * Concurrent Immunosuppressive Therapy Trials: Use of investigational agents or therapies other than standard of care post-transplant immunosuppression. * Allergy to Study Drug: Known hypersensitivity to emapalumab or any of its components. * Insufficient Baseline Data: Lack of prior baseline FEV1 data for comparison.
