0000ba16-b291-428d-b7a1-6cee104c7cfb | NCT07110246 | All | 0 | 12 Months | 25 Years | No | Inclusion Criteria:
Participants must have histologically confirmed LGG World Health Organization (WHO) Grade I or II with BRAF V600 mutation confirmed by immunohistochemistry or sequencing
Participants must have measurable tumor.
* For participants with measurable disease, this will be defined as lesions that can be accurately measured in two dimensions (longest diameter to be recorded) with a minimum size of no less than double the slice thickness. Previously irradiated lesions are considered non-measurable except in cases of documented progression of the lesion since the completion of radiation therapy. Participants without measurable disease may be considered for enrollment and followed for survival and progression purposes but will not be included as part of a measurable disease cohort.
Cohort 1:
Participants must have no prior therapy, except for surgical intervention (i.e. biopsy or resection)
Participants may currently be taking dabrafenib and trametinib as frontline therapy, with a maximum duration of 21 months and participants must not yet have met criteria for confirmed best response as defined in this protocol. For participants entering the trial currently taking dabrafenib and trametinib, they must be taking a dose that is within 20% of the standard dosing for both drugs based on age and weight. Participants who are already on dabrafenib and trametinib when enrolling on trial and whose dosing deviates more than 20% from the protocol nomogram need to be discussed with the study chairs. Eligibility for these participants will be based on ability to wean within the parameters of the protocol
Cohort 2:
* Participants must have a history of recurrent or progressive disease following prior therapy (e.g., carboplatin and vincristine, vinblastine, bevacizumab, mitogen-activated extracellular signal-regulated kinase (MEK) inhibitor, radiation therapy etc). Participants who previously completed a course of therapy with dabrafenib and trametinib, who did not progress on this therapy, and who are beyond 6 months from completion of therapy are eligible for retreatment.
** Participants may currently be taking dabrafenib and trametinib as therapy for disease recurrence, for a maximum duration of 21 months and participants must not yet have met criteria for confirmed best response as defined in this protocol. For participants entering the trial currently taking dabrafenib and trametinib, they must be taking dose that is within 20% of the standard dosing for both drugs based on age and weight. Participants who are already on dabrafenib and trametinib when enrolling on trial and whose dosing deviates more than 20% from the protocol nomogram need to be discussed with the study chairs. Eligibility for these participants will be based on ability to wean within the parameters of the protocol
Participants must have received their last dose of chemotherapy 3 weeks prior to enrollment (6 weeks for nitrosoureas) and recovered from acute adverse events due to agents administered
Participants must be at least 7 days since the completion of therapy with a biologic or small molecule agent except dabrafenib and trametinib. For any agent with known adverse events that can occur beyond 7 days after administration, the period prior to enrollment must be beyond the time during which adverse events are known to occur. Such participants must be discussed with study chairs
Radiation:
No prior radiation is allowed for participants in Cohort 1
Participants in Cohort 2 must have:
Had their last fraction of local irradiation to primary tumor ≥ 12 weeks prior to registration
Had their last fraction of craniospinal irradiation ≥ 12 weeks prior to registration
At least 14 days after local palliative radiation (small-port)
Age: ≥ 12 months and < 25 years old
Performance Score: Karnofsky ≥ 50 for participants > 16 years of age and Lansky ≥ 50 for participants ≤ 16 years of age. Participants who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score
Peripheral absolute neutrophil count (ANC) ≥ 1000/mm^3
Platelet count ≥ 100,000/mm^3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment)
A serum creatinine ≤ 1.5 upper limit of normal (ULN) based on age and gender
Total bilirubin ≤ 1.5 x ULN for age; in presence of Gilbert's syndrome, total bilirubin ≤ 3 x ULN or direct bilirubin ≤ 1.5 x ULN
Alanine aminotransferase (ALT) ≤ 3 x ULN
Aspartate aminotransferase (AST) ≤ 3 x ULN
Participants with seizure disorder may be enrolled if well controlled
Left ventricular ejection fraction (LVEF) greater than or equal to institutional lower limit of normal (LLN) by echocardiogram (ECHO) (while not receiving medications for cardiac function)
Correct QT (QTc) interval < 480 msecs
Patient must agree to adequate contraception. (The effects of dabrafenib and trametinib on the developing human fetus are unknown. For this reason and because agents as well as other therapeutic agents used on this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method birth control, or abstinence) prior to study entry, for the duration of study participation, and 4 months after completion of the study medication administration. Should a women become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately)
A legal parent/guardian or patient must be able to understand, and willing to sign, a written informed consent and assent document, as appropriate
Participants must enroll on Pediatric Neuro-Oncology Consortium (PNOC) comprehensive follow up protocol (PNOC COMP) if PNOC COMP is open to accrual at the enrolling institution
Pathology reports, next generation sequencing reports, or both, confirming BRAF V600E mutation status must be submitted at the time of enrollment
Exclusion Criteria:
Participant's tumor has any of the following additional previously known or expected activating molecular alterations:
Isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2) mutation
Histone H3 mutation (p.K28M, p.G35R, p.G35V)
Neurofibromatosis Type 1 (NF-1) loss of function alteration
Participants who are receiving any other investigational agents
History of allergic reactions attributed to compounds of similar chemical or biologic composition to dabrafenib and trametinib
Medications that are affected by the induction of CYP3A4 and CYP2C9 should be avoided or used cautiously. Dabrafenib has been shown to induce CYP3A4 and CYP2C9. In addition, dabrafenib is an in vitro inducer of CYP2B6, CYP2C8, CYP2C19, Uridine 5'-diphospho (UDP)-glucuronosyltransferase. Co-administration of dabrafenib and medications which are affected by the induction of these enzymes (including warfarin) and transporters may result in loss of efficacy. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated list such as http://medicine.iupui.edu/clinpharm/ddis/table.aspx; medical reference texts such as the Physicians' Desk Reference may also provide this information. As part of the enrollment/informed consent procedures, the participant and/or legal parent or guardian will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the participant is considering a new over-the-counter medicine or herbal product
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection
Women of childbearing potential must not be pregnant or breast-feeding
Human immunodeficiency virus (HIV) positive participants will be ineligible if HIV therapy regimen has not been stable for at least 4 weeks or there is intent to change the regimen within 8 weeks following enrollment, or if they are severely immunocompromised | |||

NCT00000102 | Congenital Adrenal Hyperplasia: Calcium Channels as Therapeutic Targets | completed | treatment | This study will test the ability of extended release nifedipine (Procardia XL), a blood
pressure medication, to permit a decrease in the dose of glucocorticoid medication
children take to treat congenital adrenal hyperplasia (CAH). | This protocol is designed to assess both acute and chronic effects of the calcium channel
antagonist, nifedipine, on the hypothalamic-pituitary-adrenal axis in patients with
congenital adrenal hyperplasia. The multicenter trial is composed of two phases and will
involve a double-blind, placebo-controlled parallel design. The goal of Phase I is to
examine the ability of nifedipine vs. placebo to decrease adrenocorticotropic hormone
(ACTH) levels, as well as to begin to assess the dose-dependency of nifedipine effects.
The goal of Phase II is to evaluate the long-term effects of nifedipine; that is, can
attenuation of ACTH release by nifedipine permit a decrease in the dosage of
glucocorticoid needed to suppress the HPA axis? Such a decrease would, in turn, reduce
the deleterious effects of glucocorticoid treatment in CAH. | 0 | 0 | NCRR-M01RR01070-0506 | 0 | 0 | 0 | 0 | ||||||||||||||||||
NCT00000105 | Vaccination With Tetanus and KLH to Assess Immune Responses. | Vaccination With Tetanus Toxoid and Keyhole Limpet Hemocyanin (KLH) to Assess Antigen-Specific Immune Responses | terminated | The purpose of this study is to learn how the immune system works in response to
vaccines. We will give the vaccines to subjects who have cancer but have not had
treatment, and to patients who have had chemotherapy or stem cell transplant. Some
patients will get vaccines while they are on treatments which boost the immune system
(like the immune stimulating drug interleukin-2 or IL-2). Although we have safely treated
many patients with immune boosting drugs, we do not yet know if they improve the body's
immune system to respond better to a vaccine. Some healthy volunteers will also be given
the vaccines in order to serve as control subjects to get a good measure of the normal
immune response. We will compare the patients and the healthy volunteers to study how
their immune systems respond to the vaccines.
There are several different types of white cells in the blood. We are interested in
immune cells in the blood called T-cells. These T-cells detect foreign substances in the
body (like viruses and cancer cells). We are trying to learn more about how the body
fights these foreign substances. Our goal is to develop cancer vaccines which would teach
T-cells to detect and kill cancer cells better. We know that in healthy people the immune
system effectively protects against recurrent virus infection. For example, that is why
people only get "mono" (mononucleosis) once under normal circumstances. When the body is
infected with the "mono" virus, the immune system remembers and prevents further
infection. We are trying to use the immune system to prevent cancer relapse. To test
this, we will give two vaccines which have been used to measure these immune responses.
Blood samples will be studied from cancer patients and will be compared to similar
samples from normal subjects. | Patients will receive each vaccine once only consisting of:
Arm A: Intracel KLH 1000 mcg (1 mg) without adjuvant, subcutaneous Tetanus Toxoid 0.5 ml
intramuscularly (this arm closed 1/2/02).
Arm B: Biosyn KLH 1000 mcg (1 mg) without adjuvant, subcutaneous tetanus toxoid 0.5 ml
intramuscularly (this arm closed 3/18/03).
Arm C: Biosyn KLH 1000 mcg (1 mg) with Montanide ISA51 (now replaced with vegetable (VG)
source after 8/31/06 to increase product safety) subcutaneous Tetanus toxoid 0.5 ml
intramuscularly (this arm open 3/18/03).
Subjects ineligible for tetanus may still receive KLH on this protocol. This is
especially true given the national shortage of tetanus vaccines. Subjects will be
eligible for tetanus when it becomes available if there has been no significant change in
treatment interventions or overall health status and it is within 3 months of the KLH
vaccine. | 0 | Replaced by another study. | 136 | 2002-07-01 | 2012-03-01 | actual | 0 | 2002LS032 | 0 | 0 | 0 | 0 | |||||||||||||
NCT00000110 | Influence of Diet and Endurance Running on Intramuscular Lipids Measured at 4.1 TESLA | completed | treatment | The purpose of this pilot investigation is to use 1 H Magnetic Resonance Spectroscopy
(MRS) to 1) document the change in intra-muscular lipid stores (IML) before and after a
prolonged bout of endurance running and, 2) determine the pattern (time course) of IML
replenishment following an extremely low-fat diet (10% of energy from fat) and a
moderate-fat diet (35% of energy from fat). Specifically, the study will evaluate the
change in IML following a 2-hour training run and the recovery of IML in response to the
post-exercise low-fat or moderate-fat diet in 10 endurance trained athletes who will
consume both diets in a randomly assigned cross-over fashion. We hypothesize that IML
will be depleted with prolonged endurance exercise, and that replenishment of IML will be
impaired by an extremely low-fat diet compared to a moderate-fat diet. Results of this
pilot study will be used to apply for extramural grant support from NIH or the US Armed
Forces to investigate the effect of dietary fat on the health and performance of
individuals performing heavy physical training. It is anticipated that this methodology
could also be employed in obesity research to delineate, longitudinally, the reported
cross-sectional relationships among IML stores, insulin resistance and obesity. | 0 | 1 | NCRR-M01RR00032-0855 | 0 | 0 | 0 | 0 | |||||||||||||||||||
NCT00000114 | Randomized Trial of Vitamin A and Vitamin E Supplementation for Retinitis Pigmentosa | completed | treatment | To determine whether supplements of vitamin A or vitamin E alone or in combination affect
the course of retinitis pigmentosa. | Retinitis pigmentosa (RP) is a group of inherited retinal degenerations with a worldwide
prevalence of about 1 in 4,000. Patients typically report night blindness in adolescence
and lose vision in the midperipheral followed by far-peripheral visual field in adulthood
due to progressive loss of both rod and cone function. Most patients have reductions in
central vision by age 50 to 80 years. Modern-day electroretinograms (ERGs) make it
possible to record retinal responses from most patients with remaining vision and thereby
monitor objectively the course of their disease.
While the natural course of retinal degeneration in the common forms of RP was being
studied, it was noted that a subgroup of patients aged 18 through 49 who were treating
themselves with both vitamin A and vitamin E and other nutritional supplements exhibited
less decline in ERG amplitude over a 2-year period. These preliminary findings, as well
as the known roles of vitamins A and E in maintaining normal photoreceptor function and
structure, prompted this randomized, controlled trial to determine whether these vitamins
alone or in combination would halt or slow the progression of the common forms of RP.
This study was a randomized, controlled double-masked trial with 2 x 2 factorial design
and duration of 4 to 6 years. Patients were assigned to one of four treatment groups:

NCT00000115 | Randomized Trial of Acetazolamide for Uveitis-Associated Cystoid Macular Edema | completed | treatment | To test the efficacy of acetazolamide for the treatment of uveitis-associated cystoid
macular edema. | Uveitis, an intraocular inflammatory disease, is the cause of about 10 percent of visual
impairment in the United States. Uveitis may lead to many sight-threatening conditions,
including cataract, vitreal opacities, glaucoma, and, most commonly, cystoid macular
edema. Reduction of swelling or edema within the retina depends on the movement of fluid
from the retina through the choroid. A number of studies indicate that this process
requires active transport of fluid ions by the retinal pigment epithelium and may involve
the carbonic anhydrase system. Current treatment of uveitis-associated cystoid macular
edema requires the use of immunosuppressive or anti-inflammatory agents. However, many
patients are either resistant or intolerant to this therapy. Recent reports suggested
that acetazolamide, a carbonic anhydrase inhibitor that is used to lower intraocular
pressure in some glaucoma patients, might be safe and effective in reducing
uveitis-associated cystoid macular edema.
Because the course of ocular inflammatory disease can be variable, a double-masked,
randomized, crossover trial was designed to test the efficacy of acetazolamide compared
with a placebo for the treatment of uveitis-associated cystoid macular edema. Randomized
adult patients received either oral acetazolamide sodium 500 mg or a matched placebo
every 12 hours for the first 4 weeks of the study. Children 8 years of age or older
received a lesser dose based on body weight. Following a 4-week period, during which no
medication was given, patients then received a 4-week course of the opposite medication.
Primary end points included reduction in cystoid macular edema (graded on fluorescein
angiography) and improvement in visual acuity (measured on standardized Early Treatment
Diabetic Retinopathy Study [ETDRS] charts). Laser acuity was also assessed as a secondary
outcome variable. Adverse effects of the acetazolamide therapy were monitored by clinical
and laboratory examinations.
A total of 40 patients were recruited for the study. Patients were seen at the beginning
of the study for baseline measurements and at 4, 8, and 12 weeks after enrollment into
the study. | 0 | 1990-12-01 | 1994-06-01 | actual | 0 | NEI-11 | 0 | 0 | 0 | 0 |
