Please assess the completion status of the following clinical trial:

Trial Title: Treatment of Alveolar Bone Defects Using Aastrom Biosciences Autologous Tissue Repair Cell Therapy

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE1/PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Age range: 20 to 70 years~* Gender: Male and female~* Patients must be able and willing to follow study procedures and instructions~* Patients must have read, understood and signed an informed consent form~* Patients must require tooth extraction as a result of caries, periodontal disease, or tooth fracture~Exclusion Criteria:~* Allergies or hypersensitivities to study related medications: amoxicillin, dexamethasone, chlorhexidine, ibuprofen, ranitidine~* Hematologic disorders/ blood dyscrasias~* Active infectious disease~* Liver or kidney dysfunction/failure- Patients will have blood drawn for serum laboratory tests, including creatinine, blood urea nitrogen (BUN), aspartate aminotransferase (AST), alanine aminotransferase test (ALT), and bilirubin. All of these must be within normal limits for a patient to be included in the study. Current University of Michigan Health System normal lab values are as follows: Creatinine (male 0.7-1.3 mg/dl; female 0.5-1.0 mg/dl); BUN (8-20 mg/dl); AST (8-30 IU/L); ALT (7-35 IU/L); Bilirubin (0.2-1.2 mg/dl).~* Endocrine disorders/dysfunctions (i.e Type I and II diabetes)~* Cancer - The explicit definition of cancer used to exclude patients is consistent with that described by the National Cancer Institute (NCI), National Institutes of Health. According to NCI, cancer is any disease in which abnormal cells divide without control and invade nearby tissues (invasive disease). These include carcinomas, sarcomas, leukemias, and lymphomas. Any patient with a history of these invasive diseases will be excluded from the study.~* Patients who currently use bisphosphonates or have a history of bisphosphonate use will be excluded from the trial.~* HIV+~* Metabolic Bone Diseases-Patients with metabolic bone diseases such as Paget's disease, hypercalcemia, moderate to severe vitamin D3 abnormalities or any other metabolic bone disease including osteoporosis and osteoporotic fractures will be excluded. The following scale will be used to determine osteoporosis in patients who have had a bone mass density (BMD) determination: Normal = T score at or above -1.0 SD; Osteopenia = T score between -1.0 and -2.5 SD; Osteoporosis = T score at or below -2.5 standard deviation (SD). Although a dexa scan will not be required, all post-menopausal women receiving osteoporosis/osteopenia related therapy will receive a dexa scan as part of their standard medical care.~* Additionally, individuals who have a medical history significant for diabetes will not be included in the study.~* Laboratory values that will define normal renal and hepatic function, as well as criteria for exclusion of metabolic bone disease are consistent with those established by the University of Michigan Health System (UMHS). Normal clinical values will be used to help assure the health of all subjects in this trial.~* Individuals who have a BMI outside normal limits or a BMI that deems them overweight (BMI \>25) will be excluded due to potential difficulties in locating appropriate surgical entry of the iliac crest during bone marrow aspiration procedure.~* The following additional exclusion criteria for regenerative sites are in alignment with those described and adapted for using bone morphogenetic protein (BMPs) to regenerate buccal wall defects (Fiorellini, Howell et al. 2005):~* Patients \< 20 and \> 60 years of age~* Pregnant women- Female patients who are of childbearing potential are excluded except those who are using hormonal or barrier methods of birth control (oral or parenteral contraceptives, transdermal patch, diaphragm plus spermicide, or condoms). Pregnancy status will be determined with a urine test and patients who are pregnant, as determined by a positive test, will be excluded from the study~* Patients with acute sinusitis~* Patients with congenital or metabolic bone disorders~* Current smokers (have smoked within 6 mos. of study onset)~* Presence of \< 4 mm of bone from apex of tooth to the alveolar crest~* \< 2 mm bone from apex to floor of maxillary sinus

- Gender: ALL
- Minimum Age: 20 Years
- Maximum Age: 70 Years
- Healthy Volunteers: f

Study Arms:
- Tissue Repair Cells (TRC) (Type: EXPERIMENTAL): Subjects will receive Tissue Repair Cell (TRC) therapy plus Gelfoam carrier
- Control (Type: SHAM_COMPARATOR): Subjects will receive the control treatment, consisting of Gelfoam carrier without Tissue Repair Cell (TRC) therapy.

Based on this trial design, predict the completion outcome and termination type (if applicable).
