Title: A Randomized, Double Blind, Multicentric, Placebo Controlled, Single Dose, Phase - i/ii Study Assessing the Safety and Efficacy of Intramuscular ex Vivo Cultured Adult Allogenic Mesenchymal Stem Cells in Patients With Critical Limb Ischemia (Cli)
Brief Summary: This clinical trial aims to study the safety and efficacy of adult mesenchymal stem cells in critical limb ischemia.


Options:
A: Inclusion Criteria:

* Patients 18 years of age or greater with atherosclerotic vascular disease that is viewed as not readily amenable to reconstructive surgery and Rutherford Category 4 ischemia (ischemic rest pain) and Rutherford Category 5 ischemia (ulceration or tissue necrosis) and by the judgment of their referring physician are not reasonable candidates for revascularization options of either percutaneous balloon angioplasty or a surgical revascularization.
* Objective evidence of severe peripheral arterial disease will include an ankle brachial index (ABI) of less than 0.5, or, in the case of patients who have vessels calcified and thereby "non-compressible" vessels metatarsal pulse volume recording (PVR) that is flat or barely pulsatile in the diseased limb on two consecutive examinations performed at least one week apart.
* Patients competent to give informed consent.
* No active malignant disease that could involve the bone marrow, or history of treatment of malignant disease that could have damaged the bone marrow.
* Before being accepted for the study the patient must be screened for human immunodeficiency virus, hepatitis B virus, hepatitis C virus, human transmissible spongiform encephalopathy, including Creutzfeldt-Jacob Disease, Treponema pallidum, and have a negative standard infectious disease panel including a CMV PCR test.
* Patients who are hemodynamically stable.

Exclusion Criteria:

* Patients with poorly controlled diabetes mellitus (HbA1C \> 8%)
* Patients with renal insufficiency (creatinine \> 2.5).
* Patients with evidence of infectious disease as determined by e. above or other medical findings.
* Pregnant women (women capable of childbearing must have a negative pregnancy test).
* Patients with cognitive impairments.
* Other comorbid disease that would be expected to result in less than one year life expectancy
* Past malignancy or history of chemotherapy or radiation affecting the bone marrow.
* History of inflammatory or progressively fibrotic conditions: .e.g., rheumatoid arthritis, systemic lupus erythematosis, vasculitic disorders, idiopathic pulmonary fibrosis, retroperitoneal fibrosis
* Infection as evidenced by WBC count of \>15,000 and/or temperature \>38 degrees C. Large area of cellulitis in the afflicted limb that in the opinion of the investigators would require the institution of antibiotics OR evidence of osteomyelitis corroborated by radiographic or scintigraphic examination
* Cardiovascular conditions:

  * Exercise limiting angina ( Canadian Cardiovascular Society Class 3 (Appendix 7);
  * Congestive heart failure (New York Heart Association class 3 (Appendix 5);
  * Unstable angina;
  * Acute ST elevation myocardial infarction (MI) within 1month;
  * Transient ischemic attack or stroke within 1 month;
  * Severe valvular disease
* Patients with any history of organ transplants;
B: Inclusion Criteria:

* Diabetes mellitus Type 1 or 2
* Peripheral occlusive arterial disease stage III or IV (Fontaine) with chronical ischemia, chronic foot ulcer, degree of severity \<5 (Wagner), older than 6 weeks, without acute wound infection
* Ulcer size 1 - 30cm2, in case of osteomyelitis only one bone should be affected no trend towards healing in the ulcer after one week of standard treatment
* Angiopathic or angioneuropathic diabetic foot syndrome with no possible option of operative or interventional revascularisation
* Age 18 - 80 years
* Declaration of patient consent
C: Inclusion Criteria:

* Clinical diagnosis of third or fourth class of peripheral atherosclerosis

Exclusion Criteria:

* Insuline dependent diabetes
* Cancer
D: Inclusion Criteria:

* Males or females with non-child bearing potential in the age group of 18-60 yrs of Indian origin.
* Established CLI, clinically and hemodynamically confirmed as per Rutherford- II-4, III-5, or III-6; Patients having Infra-inguinal arterial occlusive disease with rest pain or ischemic ulcer/necrosis, who are not eligible for or have failed traditional revascularization treatment (No option patients)
* Ankle Brachial Pressure Index (ABPI) ≤ 0.6 or ankle pressure ≤ 70 mm Hg or TcPO2 ≤ 60 mmHg in the foot
* Patients if having associated Type II Diabetes, should be on medication and well controlled (HbA1c ≤ 8%) without complications
* Patients who are able to understand the requirements of the study, and willing to provide voluntary written informed consent, abide by the study requirements, and agree to return for required follow-up visits
* Normal liver and renal function
* On regular medication for hypertension if any

Exclusion Criteria:

* Patients with CLI suitable for surgical or percutaneous revascularization as determined by the surgeon performing vascular procedure and patients with any acute/chronic inflammatory condition
* CLI patient requiring amputation proximal to trans-metatarsal level
* Patients with gait disturbance for reasons other than CLI.
* Type I diabetes
* Patients having respiratory complications/left ventricular ejection fraction \< 25%f) Stroke or myocardial infarction within last 3 months
* Patients who are contraindicated for MRA
* Have clinically serious and/or unstable inter-current infection, medical illnesses or conditions that are uncontrolled or whose control, in the opinion of the Investigator, may be jeopardized by participation in this study or by the complications of this therapy
* Documented terminal illness or cancer or any concomitant disease process with a life expectancy of less than 1 year
* Patients already enrolled in another investigational drug trial or completed within 3 months.
* History of severe alcohol or drug abuse within 3 months of screening.
* Hb% \< 10 gm%, Serum Creatinine ≥ 2mg%, Serum Total Bilirubin ≥2mg%, HbA1c \> 8%
* Women with child bearing potential, pregnant and lactating women.
* Patients tested positive for HIV 1, HCV, HBV,
