A Phase 2 interventional study of OATD-01 and Placebo in Pulmonary Sarcoidosis, sponsored by Molecure S.A.. Recruiting at 28 sites in 8 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-08.
Sponsored by Molecure S.A. · Phase 2, Interventional, and Treatment
This is a Phase 2, randomized, double-blind, placebo-controlled, adaptive, multicenter study to evaluate the efficacy, safety, tolerability, Pharmacodynamics (PD), and Pharmacokinetics (PK) of OATD-01 in the treatment of subjects with active pulmonary sarcoidosis.
Adult subjects (≥ 18 years of age) diagnosed with symptomatic pulmonary sarcoidosis and active granulomatous process captured by [18F]Fluorodeoxyglucose Positron emission tomography/computed tomography ([18F]FDG PET/CT) imaging, treatment-naïve or previously treated but currently untreated, will be enrolled in the study. The diagnosis of pulmonary sarcoidosis will be based on the diagnostic criteria for pulmonary sarcoidosis recommended by the American Thoracic Society (ATS, 2020).
Subjects will be randomized in a 1:1 ratio to receive either OATD-01 or placebo for 12 weeks. A stratification of the study population based on previous treatment status for sarcoidosis (previously treated/treatment-naïve) will be applied for statistical analysis without limitation for the ratio between the subject groups. Double-blind conditions will be kept for the whole treatment duration.
67 studies on the registry are indexed under Sarcoidosis, Pulmonary; 16 are open to participants now.
This study's planned enrollment of 96 is above the median of 55 across 50 interventional studies indexed under Sarcoidosis, Pulmonary.

Exclusion Criteria:
Potentially effective systemic or inhaled pharmacological (including ) therapy for sarcoidosis (whether pulmonary or other disease), with the exception of any of the following:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
