Weekly Vinblastine for Chemotherapy Naive Children With Progressive Low Grade Glioma (PLGGs)

September 19, 2017 updated by: Ute Bartels, The Hospital for Sick Children
The overall objective of this study is to determine the efficacy of weekly Vinblastine in chemotherapy naïve patients with progressive or incompletely resected paediatric low grade glioma, to generate estimates of the response rate, progression-free survival, toxicity and quality of daily living among the population treated and determine biologic factors which will enable us to predict tumour behaviour.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Unresectable low grade glioma (LGG) of childhood increasingly appears as a chronic condition for which multiple treatments may be required. While several studies have shown evidence of short term tumour control with chemotherapy, the progression-free survival at 5 years is unsatisfactory. In addition, several regimens currently used for this condition are associated with significant risks of side effect and long term toxicity.

We have piloted in a single arm study the feasibility and efficacy of Vinblastine for children with recurrent and refractory low grade glioma, who have failed at least one line of treatment (chemotherapy and/or irradiation). Preliminary results show promising activity with minimal toxicity.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients must have been < 18 years of age when originally diagnosed.

  2. Histologic Diagnosis: Patients must have histologic verification of LGG at original diagnosis. Exceptions are optic pathway gliomas in children with neurofibromatosis or children with large hypothalamic tumours for which a diagnostic biopsy does not seem necessary. Patients with disseminated low grade glioma are eligible.

    1. Astrocytoma Variants: fibrillary, protoplasmic, gemistocytic, mixed
    2. Pilocytic Astrocytoma
    3. Pleomorphic Xanthoastrocytoma

    8. Pilomyxoid astrocytoma
  3. Performance Level :Patients must have an ECOG performance status of 0, 1 or 2 or a Lansky/Karnofsky score > 50
  4. Life expectancy: Patients must have a life expectancy of * 2 months.

  6. Measurable Disease: Patients must have measurable disease, documented by radiographic criteria.

  7. Concomitant Medications

    1. Steroids: Steroids may be used at the time of inclusion to control progressive symptoms.
    2. Anti-epileptic medications are permitted - levetiracetam (Keppra) or clobazam (Frisium) being the preferred anti-epileptic medications for chronic use reserving phenytoin and lorazepam for acute seizure control.

Experimental: 1

Children will be treated with Vinblastine Sulphate chemotherapy via intravenous administration once a week over a period of 26 weeks. MRI disease evaluation should be performed at weeks 12 and 26 (+/- 1 week). If response on MRI at week 26 > stable (i.e. stable disease, objective or partial or complete response compared to the baseline MRI exam), continue weekly Vinblastine to the total duration of treatment (i.e. 70 weeks).

All children will be followed until they demonstrate clear signs tumour progression.
