Clinical Trial Summary

A Safety Run-In will be followed by a Double-Blinded Randomized Phase. All subjects shall meet the inclusion/exclusion criteria, and will be evaluated prior to the scheduled infusion to establish baseline.

There will be 3 subjects in the safety run-in phase and 15 subjects in the double-blinded phase.

Description:

Primary objective is to demonstrate the safety of Mesenchymal Stem Cells (MSCs) intravenously administered to subjects with cystic fibrosis.

Secondary Objective is to explore if MSCs can improve the symptoms of cystic fibrosis, including lung function, the rate of pulmonary exacerbation, systemic and local inflammation and symptom-related quality of life.

The Safety Run-In will be performed to evaluate the safety of MSC infusion into subjects with cystic fibrosis. 3 subjects will participate and they will receive a single administration of allogeneic MSCs given through intravenous infusion.

In the randomized phase the subjects will be randomized at a ratio of 1:1:1 into 3 cohorts to receive infusions. There will be a total of 15 subjects in 3 cohorts.

The total duration for each subject after infusion is 12 months, plus up to an additional 2 months for the Screening and Baseline Visits. Approximately 9 visits in total.

• Patients should be on a stable medication regimen as determined by their Cystic fibrosis physician. Allowable medications include:

• Inhaled medications (bronchodilators, steroids, pulmozyme, hypertonic saline and inhaled antibiotics to suppress chronic infections including tobramycin, amikacin, colistin, aztreonam lysine)

• Be unable to perform any of the assessments required for endpoint analysis.

• Use systemic corticosteroids (=5 mg of prednisone per day).

• Have been on intravenous or oral antibiotics within the last 4 weeks

• Have a clinical history of malignancy within 5 years (i.e., subjects with prior malignancy must be disease free for 5 years), except curatively- treated basal cell carcinoma, squamous cell carcinoma, melanoma in situ or cervical carcinoma, if recurrence occurs.

• Have congestive heart failure (NYHA Class III or IV).

• Have severe pulmonary hypertension with a right ventricle systolic pressure (RVSP) >50 mmHg as estimated by echocardiography

• Have chronic kidney disease Stage 4 or 5.

• Have a non-pulmonary condition that limits lifespan to =1 year.

• Have clinically significant autoimmune disease (e.g., rheumatoid arthritis, systemic lupus erythematosus (SLE), or inflammatory bowel disease).

• Have HIV, AIDS, or other immunodeficiency.

• Test positive for hepatitis B HsAg, viremic hepatitis C, HIV1, HIV2, HTLV-I, HTLV-II, syphilis, and West Nile Virus.

• Have a resting blood oxygen saturation of <93% (measured by pulse oximetry).

• Have documented current substance and/or alcohol abuse.

• Be a current user of tobacco products.

• Have a known hypersensitivity to dimethyl sulfoxide (DMSO).

• Have had a recent (within prior 3 months) trauma or surgery.

• Be an organ transplant recipient.

• Be actively listed (or expected to be listed) for transplant of any organ other than for a lung transplant.

• Have any clinically important abnormal screening laboratory values, including but not limited to:

• hemoglobin <12.1 g/dL (females) or <13.6 g/dL (males).

• white blood cell count < 3000/mm3.

• platelets < 150,000/mm3.

• International normalized ratio (INR) ? 1.5 not due to a reversible cause (i.e. Coumadin).

• aspartate transaminase, alanine transaminase, or alkaline phosphatase ? 2 times upper limit of normal.

• Have a sitting or resting systolic blood pressure >180 mm Hg or diastolic blood pressure >110 mm Hg at Screening.

• Have any serious comorbid illness or any other condition that, in the opinion of the Investigator, may compromise the safety or compliance of the patient or preclude successful completion of the study, or that may compromise the validity of the study.

• Be a female who is pregnant, nursing, or of childbearing potential while not practicing effective contraception (female patients must undergo a blood or urine pregnancy test at screening and prior to infusion). Females who are in childbearing age must agree to practice a highly effective form of contraception throughout the study. Highly effective forms of contraception with a low failure rate include barrier methods, oral contraception or depot contraceptives (unless on Orkambi), an intrauterine device, implantable devices.

• Be currently participating in an investigational therapeutic or device trial, or have participated in an investigational therapeutic or device trial within the previous 30 days, or participate in any other clinical trial for the duration of the time that the subject actively participates in this trial.
