Once-A-Month Steroid Treatment for Patients With Focal Segmental Glomerulosclerosis

GlomerulonephritisNephrotic Syndrome

This study will test the safety and effectiveness of a monthly dosing regimen of dexamethasone-a strong steroid medication-to treat patients with focal segmental glomerulosclerosis (FSGS). Patients with this disease have kidney fibrosis (scarring) and proteinuria (excessive excretion of protein in the urine) that, in about half of the patients eventually requires kidney dialysis or transplant. Currently, the most effective treatment for FSGS is high-dose steroids (prednisone) taken daily for 4 to 6 months. However, only about 30 percent of patients respond to this treatment, and it causes serious side effects in many patients. Other drugs, such as cyclosporin and cyclophosphamide, improve proteinuria in even fewer patients (about 10 percent) and also have serious side effects. This study will explore whether a monthly pulse dose of steroids will achieve disease remission with less toxicity. Adults and children with FSGS who: 1) have not received steroid treatment, or 2) could not tolerate daily steroid treatment, or 3) relapsed after conventional steroid treatment may be eligible for this study. Those enrolled will take dexamethasone by mouth for 4 days every 4 weeks for a total of 8 months. Patients will undergo various tests before treatment starts (baseline), during the course of treatment, and in follow-up visits to evaluate the effects of treatment as follows: Review of kidney biopsy, medical evaluation, measurement of total daily urine protein excretion and kidney function, psychiatric testing for depression or other mood disorder Measurements of blood pressure, blood chemistries and urine protein excretion - monthly during treatment Questionnaire about the effects of treatment, if any, on mood and feelings - monthly during treatment Photographs of the face and body (in underwear or shorts and tank top) to evaluate body fat distribution- baseline and 8 months Eye examinations for cataracts and glaucoma - baseline and 8 months Bone density scan (DEXA scan) of the lower spine and hip - baseline, 4 and 12 months Magnetic resonance imaging (MRI) of the hips Psychological evaluation and quality of life evaluation - baseline, 1, 2 and 8 months Blood tests for adrenal gland function - baseline, 4 and 8 months Blood and urine tests - 10, 12, 15, and 18 months Patients who achieve remission (whose urine protein levels decrease to normal) before completing the 8 months of dexamethasone will take one more dose and then stop therapy, but continue with follow-up. Patients who achieve remission but relapse may be offered a second course of treatment.

Safety and Effectiveness of Propagermanium in Focal Segmental Glomerulosclerosis Participants Receiving...

Focal Segmental Glomerulosclerosis

This study will be evaluating the safety and efficacy of propagermanium for the treatment of participants with FSGS who are already taking irbesartan by: monitoring symptoms that participants may experience while on the study, measuring levels of protein in participant's urine and kidney function during the course of the study, measuring the levels of propagermanium and irbesartan that enters into participant's urine and blood, and comparing the propagermanium outcomes to participants' pre-study and placebo outcomes. Eligible participants will randomly be assigned to one of two arms to receive both the propagermanium and placebo in different orders as follows, either: Treatment Period 1 taking a propagermanium capsule twice a day for 16 weeks, followed by a six week washout period followed by Treatment Period 2 taking a placebo capsule twice a day for 16 weeks. OR Treatment Period 1 taking a placebo capsule twice a day for 16 weeks, followed by a six week washout period followed by Treatment Period 2 taking a propagermanium capsule twice a day for 16 weeks.

Pirfenidone to Treat Kidney Disease (Focal Segmental Glomerulosclerosis)

FibrosisFocal Glomerulosclerosis3 more

This study will examine the effectiveness of the drug pirfenidone in treating focal segmental glomerulosclerosis (FSGS). Patients with this disease have kidney fibrosis (scarring) and proteinuria (excessive excretion of protein in the urine). About half of patients with FSGS eventually require kidney dialysis or transplant. Steroids, which are currently used to treat the disease, are effective in only a minority of patients. Other drugs, such as cyclosporin and cyclophosphamide, improve proteinuria in a very small percentage of patients and have serious side effects. Patients with FSGS who wish to participate in this study will undergo pre-study evaluation with blood and urine tests. Patients must be on a stable dose of an ACE inhibitor (a drug that lowers blood pressure and reduces proteinuria) for at list 6 months before starting pirfenidone therapy. (Patients who are not already taking an ACE inhibitor will be started on the drug; those who cannot tolerate ACE inhibitors will be given a different drug.) Patients with elevated cholesterol will take a cholesterol-lowering drug. A diet containing approximately 1 gram of protein per kilogram of body weight per day will be recommended. Patients will take pirfenidone by mouth 3 times a day for 12 months. Blood and urine will be tested once a month, either at NIH or by the patient's local kidney specialist. They will collect two 24-hour urine samples at the beginning of the treatment period, at 2-month intervals throughout the study, and at a 6-month follow-up. Patients will also be asked to give three to five tubes of blood and urine samples for analysis during the study. In animal studies, pirfenidone improved kidney function and proteinuria and reduced kidney scarring in rats with a disease similar to FSGS. In human studies, pirfenidone improved breathing and survival in patients with lung fibrosis.

Sirolimus for Focal Segmental Glomerulosclerosis

Focal Glomerulosclerosis

This study will determine the safety and effectiveness of sirolimus (Rapamune® (Registered Trademark)) in treating focal segmental glomerulosclerosis (FSGS), a disease involving kidney scarring and increased protein in the urine. About one-half of patients with FSGS go on to develop end-stage kidney disease within 6 years, requiring dialysis or kidney transplant. Therapies to reduce urine protein are likely to stop the progression of renal scarring and reduce the chance of developing kidney failure. However, current treatments for FSGS, such as prednisone, cyclophosphamide, and cyclosporine, are not effective in many patients and can cause serious side effects. This study will see if sirolimus, a drug with both anti-scarring and immune suppressing properties, can lower the amount of protein in the urine and slow or stop the kidney disease. Patients 13 years of age and older with FSGS who have had at least one standard treatment for FSGS may be eligible for this 24-month study. Pregnant and nursing women may not participate. Candidates will be screened with a medical history and physical examination, review of medical records and kidney biopsy, 24-hour urine collection, and blood tests. Participants will take sirolimus tablets once a day for 1 year. Three 24-hour urine collections will be done before starting treatment. Blood will be drawn to measure drug levels every week for the first month after starting treatment, then every other week for 1 month, and then every 2 months until treatment stops. Patients who do not have a complete response to the drug at low levels will have their dose increased. Patients will be seen at the NIH clinic in Bethesda, Md., for the screening visit and then at 1, 4, 8, 12, and 15 months for blood and urine tests. Additional urine collections and blood tests will be done periodically throughout the 24-month study period by the patient's local physician. Patients whose urine protein decreases on therapy will be asked to wait 3 months before starting another treatment and will monitored during that time to determine if the response is sustained. Patients whose urine protein levels do not decrease with sirolimus will not be asked to wait 3 months before starting another therapy. Follow-up with the local physician will continue at 18 and 24 months after starting the study. Patients whose urine protein levels increase with sirolimus treatment will be taken off the study and may seek other treatment at any time.

Idiopathic Focal Segmental Glomerulosclerosis (FSGS) and Treatment With ACTH

Kidney Diseases

FSGS is an immunologic disorder wherein circulating immune proteins cause damage to the kidneys and progressive injury and scarring. Corticosteroid therapy is occasionally, but not nearly universally, successful in reducing proteinuria, and when patients respond, they have a favorable prognosis. The investigators believe that ACTH therapy (H.P. Acthar Gel) can provide a more rapid, well tolerated reduction in glomerular injury.
