Cell Therapy for Craniofacial Bone Defects

Completed · Phase 1/Phase 2

Conditions studied: Cleft Palate, Trauma

In brief

The purpose of this research is to determine if a patient's own bone marrow tissue can help regenerate bone in the area of the jaw where an implant will be placed. The name of the process is called Bone Repair Cell (BRC) Therapy. A sample of bone marrow tissue will be collected and sent to a laboratory where it will be processed to form more cells. These new cells will then be transplanted in the regenerative site. The researchers are testing to see if these cells (BRC) will help form bone. The research will also determine if the implant will be more stable in the area with new bone growth.

You may not qualify if…

Allergies or hypersensitivities to study related medications: dexamethasone, chlorhexidine, ibuprofen. For patients allergic to amoxicillin a comparable substitute antibiotic will be used.
Hematologic disorders/ blood dyscrasias. Patients will have blood drawn for a complete blood count (CBC) test. Current University of Michigan Health System normal lab values are as follows: white blood count (WBC: 4.0-10.0 x103/cmm), red blood count (RBC: male 4.50-5.90 x103/cmm; female 3.90-5.30x103/cmm), hemoglobin (HgB: male 13-17.3gm/dl; female 12-16gm/dl), Hct (male 39-50.2%; female 35-48%), mean corpuscular volume (MCV: 80-100fl), mean corpuscular hemoglobin (MCH: 25-35 pg), mean corpuscular hemoglobin concentration (MCHC: 30-37%), red cell distribution width (RDW: 11.5-15.5%), Plt (150-450x103/cmm).
Active infectious disease
Liver or kidney dysfunction/failure- Patients will have blood drawn for serum laboratory tests, including creatinine, blood urea nitrogen, aspartate aminotransferase test (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)
blood urea nitrogen (BUN: 8-20 mg/dl)
AST (8-30 IU/L)
ALT (7-35 IU/L)
Bilirubin (0.2-1.2 mg/dl).
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.
Potential subjects whose laboratory values fall outside the UMHS normal ranges will be required to have medical clearance from their primary care provider prior to participation.
Endocrine disorders/dysfunctions (i.e uncontrolled Type I or II diabetes, glycosylated hemoglobin [HA1C > 7%})
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 standard deviation [SD]); Osteopenia = T score between -1.0 and -2.5 SD; Osteoporosis = T score at or below -2.5 SD.
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, 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 congenital or metabolic bone disorders
Subjects with co-morbid conditions that would affect the study outcome or interpretation of study results will be excluded
Subjects on significant concomitant drug therapy for systemic conditions (i.e. cardiovascular disease, renal dysfunction) will not be included in the study. Occasional short term use (7-14 days) of analgesics or common cold medication is permitted. Such use of these medications will be reviewed and recorded by the Investigator.
