20 Clinical Trials for Various Conditions
This study will compare two techniques to achieve increase in ridge dimensions as a preparation for dental implants using a resorbable barrier membrane and bone particulate allogenic graft hydrated with saline or a growth factor called Recombinant Human Platelet-Derived Growth Factor (rhPDGF).
The present randomized clinical trial is aimed at evaluating the efficacy of recombinant human platelet-derived growth factor in combination with collagen matrix for the treatment of multiple adjacent gingival recessions
This trial will evaluate the activity of dasatinib in combination with everolimus for children with gliomas harboring PDGFR alterations, including newly diagnosed high-grade glioma (HGG) or diffuse intrinsic pontine glioma (DIPG) after radiation (stratum A); and recurrent/progressive glioma (grade II-IV, including DIPG) (stratum B).
The aim of the study was to evaluate the safety and effectiveness of Platelet Derived Growth Factor (PDGF) mixed with b tricalcium phosphate (BTCP) for the treatment of advanced periodontal osseous defects at 6 months of healing.
This is a multi-center study to assess the safety and to determine the maximum tolerated dose of the combination of imatinib and LBH589 in patients with newly diagnosed and recurrent chordoma. For the recurrent population, those patients that do not require immediate surgical resection will be eligible. Patients will be treated with 4 cycles, followed by surgical resection if possible. If indicated, surgery may take place prior to the completion of 4 cycles.
The purpose of this study is to determine the survival, disease response, and side effects of Tasigna® (nilotinib) in patients who have malignant gliomas and are positive for Platelet Derived Growth Factor Receptor (PDGFR) amplification. This study is designed to test the hypothesis that patients with malignant gliomas with PDGFR amplification are sensitive to PDGFR kinase inhibitors.
This study is to determine if subjects with .systemic sclerosis have stimulatory autoantibodies to the PDGF receptor and to confirm activation (phosphorylation) of the PDGF receptor in skin sites with varying degrees of skin thickening
Skin cancers such as basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma lesions that develop on the head and neck are treated by Mohs surgery or wide local excision to remove all tumor cells and preserve the normal tissue. These surgical techniques may result in large wounds requiring reconstructive surgery to restore function and aesthetics. Older, frail patients are particularly vulnerable to complications from these invasive procedures often leaving them to care for chronic wounds until a split-thickness skin graft can be placed. Recombinant human platelet-derived growth factor (rhPDGF) is a manufactured protein that signals through the PDGF receptor, PDGFRβ, to mediate inflammation, granulation, angiogenesis, and remodeling during wound healing and skin repair and is FDA-cleared for diabetic neuropathic ulcers and periodontal bone and soft tissue reconstructions. Preclinical and clinical data suggest that rhPDGF may be a viable therapeutic strategy to augment the reconstruction of these complex surgical wounds by accelerating healing and reducing the time-to-readiness for skin graft placement.
The average success rate for healing and remission of complex perianal fistulas, idiopathic or Crohn's-related, is approximately 50%. These abnormal connections between the rectum and the outside skin remain a major clinical challenge in need of new treatments aimed at tissue repair. Platelet-derived growth factor drives wound healing and tissue regeneration, and manufactured PDGF is currently used to heal diabetic foot ulcers and regenerate bone in periodontal and orthopedic patients. Manufactured recombinant human PDGF has the potential to improve the success rate for complete healing of complex perianal fistulas, reduce the recurrence rate due to reopening of the fistula tract, and avoid complications associated with routine surgical interventions.
The purpose of this study is to determine the safety and efficacy of combination therapy with pembrolizumab (MK-3475) and lenvatinib (E7080/MK-7902) in participants with triple negative breast cancer (TNBC), ovarian cancer, gastric cancer, colorectal cancer (CRC), glioblastoma (GBM), biliary tract cancers (BTC), or pancreatic cancer.
Lucitanib is an oral multi kinase inhibitor designed to block the action of certain molecules called "angiogenic factors" that may cause tumors to grow. These factors are called vascular endothelial growth factor (VEGF), platelet derived growth factor receptor (PDGFR) and fibroblast growth factor (FGF). Lucitanib is experimental and not approved by the FDA for the treatment of cancer. The purpose of this study is to look at the effects of lucitanib in cancer patients whose cancers harbor aberrations in FGFR, VEGFR, PDGFR or other markers predicted to be sensitive to lucitanib. This study will also look for biomarkers in samples of blood and tumor tissue to identify patients most likely to respond to lucitanib. Biomarkers are substances such as genetic material (DNA and RNA) and proteins found in blood and tumor tissue that might show if a cancer patient will respond or not respond to a drug.
The purpose of this study is to evaluate the safety and efficacy of X-82 in the treatment of vision loss due to wet AMD.
The purpose of this study is to evaluate the dose, antitumor activity, safety and pharmacology of MEDI-575 in combination with carboplatin/paclitaxel in subjects with previously untreated, advanced non-small cell lung cancer (NSCLC).
This study is to evaluate the safety, absorption rate and side effects associated with the study drug. Healthy volunteers will be given a single dose of the drug in Part 1. Subjects will be dosed at the same time at several different sites. In Part 2 of the study elderly volunteers will participate in a 14 day repeat dose session receiving either study drug or a placebo (sugar pill). Data from at least 7 days of safety will be reviewed from the first set of volunteers before increasing the doses for the next set. All results will be used for planning the next study.
The purpose of this study is to evaluate the safety and tolerability of imatinib mesylate in combination with panitumumab for the treatment of stage IV colorectal cancer that has spread to the liver. It will also assess the whether imatinib mesylate, either alone or in combination with panitumumab, is effective in treating this type of cancer. In addition, the study will evaluate the feasibility of a predefined lab score and whether it can predict which patients will respond to treatment with imatinib mesylate.
Platelet Derived Growth Factor (PDGF) is a potent mitogen for a wide range of cell types including fibroblasts, smooth muscle and connective tissue. Recombinant human platelet derived growth factor (R-Pdf/Gbb) has biologic activity similar to endogenous platelet derived growth factor (PDGF). Biologic activity of PDGF includes encouraging chemotaxis and proliferation of cells responsible for wound repair and it augments production of granulation tissue. The growth factor rhPDGF is found effective in patients having diabetic foot ulcer grade III and IV. The nature of wounds in the third degree burns is similar so far as healing process is concerned. The purpose of this study is to test the hypotheses that the application of R-Pdf/Gbb 0.01% gel on the third degree thermal and electrical burns will heal these wounds within 3 months and there will be improvement in general condition of the patients without any complications.
When a tooth is extracted the ridge of bone that held the tooth in place begins to heal and over time new bone grows to fill the empty space left by the missing tooth. Sometimes this process works very well and new bone grows to completely fill the socket, at other times new bone fails to fill in the space completely and patients are left with uneven bone-fill. Grafted extraction sockets may fill with bone faster and more evenly than those without grafts, allowing the dentist to have greater control over the healing process and to repair the area with dental implants in a shorter period of time. This study will help determine if grafting an extraction socket, with or without enriching the graft material, is an added benefit when compared to allowing the socket to heal naturally. The study will also assess how well two different dental implant designs used to restore the area will function over time.
An open label multi-site phase II clinical trial of dose escalated sunitinib malate given orally once daily on days 1-28 of each 42-day cycle. Treatment will be continued until there is either disease progression or cumulative or acute toxicity which in the opinion of the treating physician compromises the ability of the patient to receive treatment or patient desire to stop treatment.
Patients with diabetes may develop chronic wounds that respond poorly to treatment. Gene therapy with the platelet-derived growth factor-B gene has been shown to help with the healing of chronic wounds. This study will evaluate a new way to deliver the gene to the wound tissue.
The purpose of this study is to evaluate the safety and efficacy of the tyrosine kinase inhibitor, imatinib mesylate (Gleevec ) in reducing peripheral blood eosinophilia in patients with the myeloid form of hypereosinophilic syndrome (HES). Patients with the hypereosinophilic syndrome who meet a set of criteria designed to select patients with the myeloid form of the disease, as well as patients without myeloid disease who are refractory to standard therapy for HES, will be admitted on this protocol. A thorough clinical evaluation will be performed with emphasis on potential sequelae of eosinophil-mediated tissue damage. A baseline bone marrow will be obtained to exclude leukemia or lymphoma and to assess the degree and nature of eosinophilopoiesis. Bone marrow, blood cells and/or serum will also be collected to test for the presence of a recently described mutation that is associated with imatinib-responsiveness in HES, and to provide reagents (such as DNA, RNA, and specific antibodies) and for use in the laboratory to address issues related to the mechanism of action of imatinib mesylate in HES. Imatinib mesylate will be initiated at a dose of 400 mg daily, the FDA-approved dose for the treatment of chronic myelogenous leukemia. In patients who demonstrate a complete clinical and hematologic response to imatinib therapy and who do not have life-threatening disease, the dose will be decreased gradually to 100mg daily and then discontinued. In order to minimize bone marrow suppression, other myelosuppressive agents will be tapered and discontinued during the first week of therapy with imatinib mesylate. Complete blood counts will be performed weekly for the first month and biweekly thereafter. Clinical assessments will be performed every three months to assess progression of end organ damage. In patients who demonstrate a complete clinical and hematologic response to imatinib therapy and who do not have life-threatening disease, the dose will be decreased gradually to 100 mg daily and then discontinued. In the event of clinical, hematologic or molecular relapse during the taper, the imatinib dose will be increased to a maximum of 600 mg daily to achieve a second remission. Laboratory monitoring will be performed as above except for molecular monitoring which will be monitored monthly if drug is discontinued or molecular relapse occurs. Once a stable dosing regimen is achieved for greater than or equal to 6 months in subjects who have undergone dose descalation or greater than or equal to 2 years in subjects receiving 300-400 mg of imatinib daily who did not qualify for dose de-escalation, the frequency of NIH visits and end organ assessments will be decreased to 6 months, with molecular monitoring every 3 months and monthly routine laboratory assessments. ...
