Brief summary: This study is a phase 1, first-in-human, open-label, non-randomized, dose escalation safety study of 18 participants, between 39 and 69 years of age, with mild to moderate chronic obstructive pulmonary disease, treated with SORT-COPD (SMS cells).

The primary objective of this study is to determine the safety of SORT-COPD (SMS cells) at three doses in people with chronic obstructive pulmonary disease.

Detailed description: The suspension of stem cells will be put in a medical nebulizer machine, commonly used to deliver medicines into the lungs through inhalation. This means that the participants will breathe in the mist containing the SMS cells, produced by the nebulizer machine. This is a Phase I First-in-Human study, which indicates that this treatment is being studied for the first time in humans.

18 participants are expected to be enrolled into this study. Participants will be divided into three groups of six volunteers, with the first group receiving the lowest dose of the study treatment, the second group receiving a higher dose, and the third group receiving the highest dose. Between each of the three groups, there will be a pause to permit detection of any short-term adverse effects of the treatment at a specific dose.

Participants will be treated with the study drug, SORT COPD (Small Mobile Stem Cells), delivered via a medical nebuliser on the 1st, 4th, and the 8th days of the study in-clinic. The nebuliser treatment involves inhaling mist from a mouthpiece attached to a standard medical nebuliser machine and takes about 10 to 15 minutes to complete.

The volume to be nebulised is 3 millilitres (less than one teaspoon). Participants in the cohort 1 (low dose) will receive 1.2 billion cells/ml. Participants in the cohort 2 (medium dose) will receive 2.4 billion cells/ml. Participants in the cohort 3 (high dose) will receive 4.8 billion cells/ml.

The study treatment (SMS) cells will be given in three different concentrations with the lowest dose given to the 1st group of 6 participants, with the dose doubled for each group. The members of each group will receive the same dose at each treatment visit.

Participants will actively be in the study for up to 5 or 6 weeks, including the initial screening and testing period before the treatment is applied, during treatment, and about 4 weeks after the first treatment. Also, about 3 to 6 months after the study, participants will be contacted via telephone to answer some questions about their state of health, which will be the end of the study.

Individual participant duration will be up to a maximum of 15 months.

Eligibility criteria: Inclusion Criteria:

1. Aged 39 to 69 years (inclusive).
2. Female participants:

   A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies:

   Is a woman of nonchildbearing potential (WONCBP) OR Is a woman of childbearing potential (WOCBP) and using an acceptable contraceptive method from screening until 30 days after the last dose of study intervention.

   A WOCBP must have a negative highly sensitive pregnancy test (urine or serum as required by local regulations) at Screening and on Day 1, prior to administration of study intervention.

   If a urine test cannot be confirmed as negative (e.g., an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive.

   The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
3. Male participants:

   Male participants are eligible to participate if they agree to the following during the study intervention period and for at least 30 days after the last dose of study intervention:

   Refrain from donating fresh unwashed semen. Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent OR must agree to use contraception/barrier (male condom).
4. Has a diagnosis of mild or moderate COPD-C (cigarette smoking COPD) or COPD-P (biomass and pollution exposure COPD) according to the 2023 Global Initiative for Chronic Obstructive Lung Disease (GOLD) Criteria.

   Lung impairment will be determined with post-bronchodilator FEV1 spirometry.
5. Has previously received treatment for COPD-C or COPD-P.
6. Has stable COPD disease state, defined as no exacerbations in the 12 weeks prior to screening, no hospitalizations in the 12 weeks prior to screening, and no changes in COPD medication in the 28 days prior to screening.
7. Agrees to comply with study specific procedures and visits, including non-smoking during the treatment and follow-up periods of the study.
8. Willing and able to provide written informed consent.

Exclusion Criteria:

1. Previous or current diagnosis of COPD-G, COPD-D, COPD-I, COPD-A or COPD-U; asthma, congestive heart failure, bronchiectasis, tuberculosis, obliterative bronchiolitis or diffuse panbronchiolitis.
2. Previous or current history of respiratory failure other than due to COPD (e.g. restrictive lung disease, sarcoidosis, tuberculosis, idiopathic pulmonary fibrosis, bronchiectasis, CMV pneumonitis, cystic fibrosis, asbestosis, silicosis or farmer's lung disease), or detection of any of these conditions through screening CT scanning.
3. History of COVID associated pneumonia with hypoxemic respiratory failure in the 12 weeks prior to screening.
4. Current use, or use within 21 days of screening, of systemic corticosteroids. Participants on inhaled corticosteroids or combined inhaled therapies can be included, however must schedule inhaled therapies 12 hours prior to dosing IP and 12-hours post dosing IP.
5. Any history of chronic liver disease, or abnormal liver function at screening, defined as:

   Alanine transaminase (ALT) and/or aspartate aminotransferase (AST) more than 2.5 times the upper limit of normal (ULN) Total bilirubin more than two times the ULN Participants with documented Gilbert's syndrome are permitted to enter the study.
6. History of chronic renal insufficiency, defined as and eGFR \< 90 mL/min/1.73 m2. Participants without a history of chronic renal insufficiency, who at screening have an eGFR detected between 60-89 mL/min/1.73 m2, should have their eGFR repeated as per standard clinical procedure.
7. Uncontrolled hypertension, or current hypertension controlled on more than two medications.
8. History, within the last two years, of coronary artery disease, coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty, severe peripheral arterial disease, cerebrovascular disease (including history of transient ischemic attack or cerebrovascular accident), or any such history that, in the opinion of the investigator, will impact participation in the study.
