General information about the trial
|
|||
Main objective of the trial |
The primary objective of the trial was to assess the efficacy of CMK389 in participants with chronic pulmonary sarcoidosis.
|
||
Protection of trial subjects |
The study was in compliance with the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All the local regulatory requirements pertinent to safety of trial subjects were also followed during the conduct of the trial.
|
||
Background therapy |
Participants were required to be on either Methotrexate or Azathioprine (no dose requirement) and on 5-15mg/day of prednisone for at least 6 months prior to screening. Methotrexate/Azathioprine was discontinued in the Run-In period and prednisone was titrated during the trial. Hydroxychloroquine was allowed but not required during the trial. | ||

To assess the effect of CMK389 compared to placebo after 16 weeks of treatment on spirometry (Forced Vital Capacity). Forced Vital Capacity (FVC) is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible.

End point description |
The Clinical Status Evaluation (CSE) served as a safety evaluation and served to establish the patient's clinical status (Clinical Status Determination [CSD]). CSE was performed prior to the titration of steroids, and the CSD guided selection of the next dose of steroids. Participants with CSD of "improved" or "stable" decreased steroid dose by 1 step on the dosing scale. Participants with CSD of "deteriorating" were ineligible to continue the study (if found during the run-in epoch or at study Day 1); or they increased steroid dose by 1 step (if found during the treatment epoch).

FEV1 (forced expiratory volume in one second) is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation, measured through spirometry testing. The least-squares means for change from baseline in FEV1 to assess the effect of CMK389 compared to placebo after 16 weeks were obtained from a mixed effects model for repeated measures (MMRM). A positive change from baseline in pre-dose FEV1 is considered a favourable outcome.

Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
13 Aug 2019 |
The purpose of this amendment was to make operational changes to the visit design to reduce patient and site
burden as well as to clarify the procedure in case of premature discontinuation. |
||
17 Sep 2019 |
The purpose of this amendment was to make changes to the inclusion criteria and is based on feedback from sites regarding
feasibility. The update Inclusion criteria #7 is expected to improve the recruitment rate since
lower doses of prednisone (or equivalent) are more common in clinical practice. Now, in the
absence of higher prednisone doses, Inclusion criteria #8 has been added as a marker of
clinically significant disease |
||
11 Dec 2019 |
The purpose of this amendment was to answer to comments from the U.S. Food and Drug
Administration (FDA) to add clarifying statements to the exclusion criteria, specify a more
objective grading scale for the reporting of Adverse Events, and add instructions for monitoring
an adverse event of special interest (hypersensitivity reactions). |
||
17 Apr 2020 |
The purpose of this amendment was to answer to comments received from the Paul-Ehrlich-Institut
(PEI) in Germany. |
||
20 Jul 2020 |
The purpose of this amendment was to answer to comments received from the Medicines &
Healthcare products Regulatory Agency (MHRA) in the United Kingdom |
||
01 Apr 2021 |
The main purpose of this amendment was to revise the inclusion/ exclusion criteria to allow for
facilitated recruitment in line with the study rational, and clarify
trial conduct. Age and BMI limits are expanded. Inclusion criteria #6 has been clarified to be in line with the
study rationale and to include patients with <15% extent of fibrosis instead of <15% reticulation.
Pregnancy follow up was re-assessed based on predicted time for IL-18 levels to return
within the normal range in healthy volunteers and reduced to 8 weeks after EOS (i.e., 24 weeks
after last study treatment). Rescreening is now permitted.
The restriction period for administration of live/attenuated vaccines prior to CMK389 treatment
is reduced from 3 months to 1 month. The immune response of the vaccine would already be
very high and it is therefore expected to have a low risk of any negative impact on either the
efficacy or safety profile of the vaccine. |
||
11 Aug 2021 |
The main purpose of this amendment was to include Patient Reported Outcomes (PROs)
assessments and update the list of eligibility criteria.
PROs are added to the protocol to collect more information about health-related quality of life
and health status in interstitial lung diseases. These are important parameters of disease activity
and prognosis. Both disease symptoms and treatment side effects can impact patients’ quality
of life. |
||
23 Jun 2022 |
The main purpose of this amendment was to revise the inclusion/exclusion criteria to allow for
facilitated recruitment in line with the study rationale. |
