The Diabetes Control and Complications Trial (DCCT,1983-1993) compared intensive therapy aimed at near-normal glycemia versus conventional therapy with no specific glucose targets in 1441 subjects with type 1 diabetes (T1DM) over a mean follow-up of 6.5 years. Intensive therapy reduced the risks of retinopathy, nephropathy, and neuropathy by 35-76%. The level of glycemia was the primary determinant of complications. We also described the adverse effects of intensive therapy; assessed its effects on cardiovascular disease (CVD) risk factors, neurocognition and quality of life; and projected the lifetime health-economic impact. After the primary DCCT results were reported in 1993, intensive therapy aiming for a HbA1c <7% was adopted world-wide as standard-of-care for T1DM. The Epidemiology of Diabetes Interventions and Complications (EDIC, 1994-present) is the observational follow-up study of the DCCT cohort. Micro- and cardio-vascular complications and a wide range of established and putative risk factors, including genetic and epigenetic factors, have been measured with standardized methods, carefully documented and events adjudicated. EDIC has notably shown that the early beneficial effects of intensive versus conventional therapy on complications persisted for ~15 years despite the convergence of HbA1c levels in the two groups during EDIC, a novel concept termed metabolic memory. Prior intensive therapy was also shown to reduce substantially the risk of CVD events and mortality. The overarching goals for the current cycle (2022-2027) are to study the occurrence and identify potentially modifiable risk factors of the more advanced microvascular and cardiovascular complications and physical and cognitive dysfunction that are occurring with increasing diabetes duration and age. With increasing longevity, the increased adiposity that has affected patients with T1DM, including EDIC participants, has potential adverse consequences. Thus, the impact of diabetes duration, aging and adiposity on morbidities and their underlying risk factors will be studied. The results will guide treatment priorities as T1DM patients age.
RATIONALE: Interferon alfa may interfere with the growth of cancer cells. Low doses of interferon alfa may be as effective as high doses. PURPOSE: Randomized phase III trial to compare the effectiveness of low-dose or high-dose interferon alfa in treating patients who have newly diagnosed chronic myelogenous leukemia.
The goal of the study is to gain a better understanding of the molecular changes responsible for causing prostate cancer and that examination of tissue and blood samples will help in the development of improved screening and therapeutic approaches.
RATIONALE: Interferon alfa may interfere with the growth of cancer cells. It is not known whether giving high-dose or low-dose interferon alfa is more effective than no further therapy in treating patients with stage III melanoma. PURPOSE: Randomized phase III trial to compare the effectiveness of high- or low-dose interferon alfa with that of no further therapy following surgery in treating patients who have stage III melanoma.
RATIONALE: Boron neutron capture therapy may selectively kill tumor cells without harming normal tissue. PURPOSE: Phase I trial to study the effectiveness of boron neuron capture therapy in treating patients with stage III melanoma.
RATIONALE: Vaccines may make the body build an immune response to kill melanoma cells. PURPOSE: Phase I/II trial to study the effectiveness of vaccine therapy in treating patients with metastatic melanoma.
RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and deliver tumor-killing substances to them without harming normal cells. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Sometimes the transplanted cells can make an immune response against the body's normal tissues. Cyclosporine may prevent this from happening. PURPOSE: Phase I trial to study the effectiveness of radiolabeled monoclonal antibody plus cyclosporine and peripheral stem cell transplantation in treating patients who have metastatic breast cancer that has not responded to previous therapy.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of combination chemotherapy consisting of fluorouracil, leucovorin, and gemcitabine in treating patients with recurrent or metastatic colorectal cancer.
This trial is designed to study the effects of various mechanistically unique medications in controlling excessive increases in heart rate with standing and in improving the symptoms of orthostatic intolerance in patients with this disorder.
RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known whether giving monoclonal antibody therapy is more effective than a placebo in treating patients with ovarian epithelial, fallopian tube, or peritoneal cancer who have responded to surgery and chemotherapy. PURPOSE: Randomized phase II trial to study the effectiveness of monoclonal antibody therapy in treating patients with residual disease from stage III or stage IV ovarian epithelial, fallopian tube, or peritoneal cancer following surgery and chemotherapy.
