A Phase 2 interventional study of EXPD-101/FXS7553 Dose 1 and EXPD-101/FXS7553 Dose 2 in Chronic Obstructive Pulmonary Disease (COPD), sponsored by Expedition Therapeutics, Inc. Recruiting at 35 sites in 4 countries. Open to participants aged 40 Years to 85 Years. Per ClinicalTrials.gov, last updated 2026-10-28.
Sponsored by Expedition Therapeutics, Inc · Phase 2, Interventional, and Treatment
This is a Phase 2 study of the efficacy, safety, tolerability and pharmacokinetics of two doses of EXPD-101 in participants with COPD. Study participants will be randomized to receive either study drug or placebo administered once daily for 52 weeks.
5,520 studies on the registry are indexed under Pulmonary Disease, Chronic Obstructive; 856 are open to participants now.
This study's planned enrollment of 600 is above the median of 62 across 3,839 interventional studies indexed under Pulmonary Disease, Chronic Obstructive.

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.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
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.
From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
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.
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.
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.
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.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
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.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Change From Baseline in Quality of Life Questionnaire - St. George's Respiratory Questionnaire (SGRQ)
The SGRQ is a validated, self-administered patient-reported outcome (PRO) that assesses symptoms, functioning, and health-related quality of life for participants with Chronic Obstructive Pulmonary Disease (COPD). It contains 50 items in 2 parts. Part 1 has 8 items for assessing the severity of respiratory symptoms (cough, sputum production, wheeze, breathlessness, and the duration and frequency of attacks of breathlessness or wheeze). Part 2 has 42 items across 2 components (Activity and Impacts) related to daily activities and psychosocial impacts of the participant's respiratory condition. The SGRQ total score is calculated as the sum of scores across symptoms, activity, and effects, with 0 indicating the best possible health status and 100 indicating the worst possible health status. A decrease in 4 units in the total score corresponds to a clinically significant improvement in the quality of life.
Time frame: Baseline, Week 52
Change From Baseline at Week 52 in Postbronchodilator Forced Expiratory Volume in 1 Second (FEV1) and forced vital capacity (FVC)
FEV1 is used to assess lung function and is the maximum amount of air that can be forced out in one second after first second after taking a forced expiration as measured by a spirometer. Postbronchodilator FEV1 tests included spirometry tests performed after administration of bronchodilator. FVC is used to assess lung function and is the total volume of air that can be forced out after taking a deep breath as measured by a spirometer.
Time frame: Baseline, Week 52
Change From Baseline at Week 52 in Quality of Life Questionnaire - Evaluating Respiratory Symptoms (E-RS): COPD
The E-RS:COPD™ scale, a part of the EXACT tool, is a derivative instrument used to measure the effect of treatment on the severity of respiratory symptoms in stable COPD. The E-RS is an 11-item participant-reported diary to measure respiratory symptom items contained in the 14-item EXACT. Summation of E-RS: COPD item responses produces a total score ranging from 0 to 40, with higher scores indicating greater severity. In addition to the total score, symptom domain scores can be calculated for breathlessness (5 items; score range: 0-17), cough and sputum (3 items; score range: 0-11) and chest symptoms (3 items; score range: 0-12) by summing the responses of items within a respective domain. As with the total score, higher domain scores indicate greater severity.
