Clinical Trial Summary

The purpose of this study is to evaluate the safety, efficacy, pharmacokinetics, and pharmacodynamics of itacitinib in participants with post-lung transplant bronchiolitis obliterans syndrome (BOS).

Recruitment information / eligibility

• Status: Terminated
• Enrollment: 23
• Est. completion date: October 13, 2023
• Est. primary completion date: October 13, 2023
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Double lung transplantation = 1 year before informed consent. Confirmed BOS progression to Grade 1, 2, or 3 diagnosed within 1 year of screening

*Confirmed BOS progression to Grade 1, 2, or 3 diagnosed within 2 years of screening AND:

• A = 200 mL decrease in FEV1 in the previous 12 months

OR

*A = 50 mL decrease in FEV1 in the last 2 measurements.

• Willingness to avoid pregnancy or fathering children.

Exclusion Criteria:

• History of a single lung transplant

• FEV1 decline attributable to cause(s) other than BOS.

• Participants who have had any significant change (eg, addition of new agents) in an immunosuppressive regimen in the 4 weeks before screening.

• Untreated and/or symptomatic gastroesophageal reflux disease.

• Significant infectious comorbidities including invasive fungal disease, B. Cepacia, non TB mycobacteria, or TB.

• Receipt of JAK inhibitor therapy after lung transplant for any indication. Treatment with a JAK inhibitor before lung transplant is permitted.

• Laboratory values at screening outside the protocol-defined ranges.

• Active HBV or HCV infection that requires treatment, or at risk for HBV reactivation (ie, positive HBsAg).

• Known HIV infection.

• History of active malignancy within 3 years of screening.

• Women who are pregnant or breastfeeding.

• Treatment with an investigational agent, procedure, or device within 30 days of enrollment, or within 5 half-lives of the investigational product, whichever is longer.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Phase 1: Number of treatment-emergent adverse events	Defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study drug until 30 days after the last dose of study drug.	Up to approximately 24 months
Primary	Phase 1: Change from baseline in forced expiratory volume in 1 second (FEV1)		Week 12
Primary	Phase 2: Change from baseline in FEV1 response rate	Defined as the proportion of participants demonstrating a = 10% absolute increase in FEV1 compared to baseline.	Week 12
Secondary	Phase 1 and 2: Duration of FEV1 response	Defined as the time of the onset of response (= 10% absolute increase in FEV1 compared to baseline) to BOS progression or loss of clinical benefit as determined by the investigator.	Up to approximately 24 months
Secondary	Phase 1 and 2: Time to progression	Defined as the interval between the start of treatment and BOS progression (= 10% absolute decrease in FEV1 compared to baseline), or death.	Up to approximately 24 months
Secondary	Phase 1 and 2: Change from baseline in SGRQ total score	St. Georges Respiratory Questionnaire, a disease-specific instrument designed to measure impact on overall health, daily life, and perceived well-being in patients with obstructive airway disease.	Up to approximately 24 months
Secondary	Phase 1 and 2: Change from baseline in QOL-SF-12 questionnaire	A 12-item subset of the SF-36 v2 scale that will capture changes in health status during the course of treatment.	Up to approximately 24 months
Secondary	Phase 1 and 2: Categorical summary or change from baseline in EQ-5D-3L questionnaire	A descriptive classification consisting of 5 dimensions of health: mobility, self-care, usual activities, anxiety/depression, and pain/discomfort.	Up to approximately 24 months
Secondary	Phase 2: Overall Survival	Defined as the interval between the start of treatment and the date of re-transplantation or death due to any cause.	Up to approximately 24 months
Secondary	Phase 1 and 2: Cmax of itacitinib	Maximum observed concentration.	Up to Week 4
Secondary	Phase 1 and 2: Cmin of itacitinib	Minimum observed plasma or serum concentration over the dose interval.	Up to Week 4
Secondary	Phase 1 and 2: Tmax of itacitinib	Time to maximum concentration.	Up to Week 4
Secondary	Phase 1 and 2: AUC0-t of itacitinib	Area under the plasma or serum concentration-time curve from time = 0 to the last measurable concentration at time = t.	Up to Week 4
Secondary	Phase 1 and 2: Cl/F of itacitinib	Apparent oral dose clearance.	Up to Week 4
