Oral D-penicillamine for the prevention of retinopathy of prematurity in very low birth weight infants: a randomized, placebo-controlled trial. [2010.09]
PURPOSE: To compare prophylactic enteral D-penicillamine (DPA) with placebo for prevention of 'retinopathy of prematurity (ROP) or death' among very low birth weight (VLBW) infants... CONCLUSION: Prophylactic enterally administered DPA suspension in a dose 100 mg/kg/dose 8 h for 3 days, followed by 50 mg/kg once per day for next 11 days, does not prevent 'any stage ROP or death' or 'ROP requiring treatment' in VLBW infants. DPA is well tolerated and does not have any major short-term adverse effects. (c) 2010 The Author(s)/Journal Compilation (c) 2010 Foundation Acta Paediatrica.
Oral D-penicillamine for the prevention of retinopathy of prematurity in very low birth weight infants: a randomized, placebo-controlled trial. [2010.04.16]
Abstract Purpose: To compare prophylactic enteral D-penicillamine (DPA) with placebo for prevention of 'retinopathy of prematurity (ROP) or death' among very low birth weight (VLBW) infants. Methods: This was a double-blind, single-centre, randomized, placebo-controlled trial with stratification (for birth weight <1250 and >/=1250 g) and blocking...
High-dose versus low-dose D-penicillamine in early diffuse systemic sclerosis trial: lessons learned. [2004.02]
OBJECTIVES: To review important findings, or lessons, that were learned about measures of response, design, conduct, and analysis of a randomized, controlled trial (RCT), even though the trial failed to demonstrate efficacy of d-penicillamine... CONCLUSIONS: Even in studies that are therapeutically "negative," careful evaluation of the data can examine other hypotheses and thereby provide important insights into other aspects of trial design, outcome measures, patient function, and trial conduct.
The Disability Index of the Health Assessment Questionnaire is a predictor and correlate of outcome in the high-dose versus low-dose penicillamine in systemic sclerosis trial. [2001.03]
OBJECTIVE: To explore the clinical implications of a score of > or =1.0 on the Disability Index of the Health Assessment Questionnaire (HAQ DI) at the first patient visit, and to examine the implications of improvement in HAQ DI score over 2 years in a cohort of systemic sclerosis (SSc) patients with diffuse cutaneous scleroderma... CONCLUSION: A baseline HAQ DI score of > or =1.0 predicted mortality over 4 years. Improvement in the HAQ DI score in these patients with diffuse scleroderma was associated with improvement in skin thickening, hand function, oral aperture, lung function, signs of arthritis, serum creatinine level, and the investigator's global assessment of improvement. The HAQ DI is a self-administered questionnaire that SSc patients can complete easily and rapidly and that gives the practicing physician important information about prognosis, patient status, and changes in disease course over time.
D-penicillamine is not an effective treatment in systemic sclerosis. 
Based on open studies. D-penicillamine (DPA) has been used for the treatment of systemic sclerosis (SSc) but we believe the controlled trial of this drug in SSc does not support its use to treat this disease.
Clinical Trials Related to Cuprimine (Penicillamine)
Penicillamine Chelation for Children With Lead Poisoning [Active, not recruiting]
Childhood Lead Poisoning is a widespread disease that has few effective treatments. The
specific aims of this proposed clinical trial are threefold:
- To determine whether a six-week course of a newly formulated d-penicillamine suspension
will effectively reduce blood lead level in children aged 6 months to 16 years with
blood lead levels of 15-25 μg/dL.
- To determine whether d-penicillamine chelation produces a sustained reduction in blood
lead level in comparison with succimer and other lead chelators which always produce a
significant post-treatment "rebound".
- To determine whether chelation with d-penicillamine improves the physiologic
disturbances that can be measured in children with blood lead levels in this range.
Penicillamine, Low Copper Diet, and Radiation Therapy in Treating Patients With Glioblastoma [Active, not recruiting]
RATIONALE: Penicillamine may stop the growth of glioblastomas by stopping blood flow to the
tumor. A diet low in copper may interfere with the growth of brain tumor cells. Radiation
therapy uses high-energy x-rays to damage tumor cells. Combining these therapies may be
effective in treating glioblastoma.
PURPOSE: Phase II trial to study the effectiveness of penicillamine, a low copper diet, and
radiation therapy in treating patients who have newly diagnosed glioblastoma.
Effect of Increasing Doses of Cystine Binding Thiol Drugs on Cystine Capacity in Patients With Cystinuria [Recruiting]
The purpose of this study is to evaluate the effect of escalating doses of cystine biding
thiol drugs, including tiopronin and d-penicillamine, on the urinary cystine capacity, which
is a measure of the amount of cystine in the urine, in patients with cystinuria. The overall
goal will be to help guide therapy and ultimately minimize unnecessary side effects caused
by larger doses.
Cystine Capacity Clinical Study (CysCap) [Recruiting]
The purpose of this study is to determine whether urinary cystine capacity, an assay used to
measure the amount of cystine in the urine, can be used to predict stone recurrence in
patients with cystinuria.
Study of Positron Emission Tomography and Computed Tomography in Guiding Radiation Therapy in Patients With Stage III Non-Small Cell Lung Cancer [Recruiting]
RATIONALE: Imaging procedures, such as positron emission tomography (PET) scan and CT scan,
may help doctors plan radiation therapy for patients with non-small cell lung cancer.
PURPOSE: This randomized phase II trial studies how well PET/CT scan work in guiding
radiation therapy compared to standard radiation therapy treatment in patients with stage
III non-small cell lung cancer.
