Aflac ST1001 Prolonged Isotretinoin (Aflac ST1001)
Prolonged Isotretinoin Therapy in Patients With High Risk Neuroblastoma
Neuroblastoma is a cancer of the nervous system and accounts for 15% of cancer related deaths in children. With the advancement of treatment therapies, the long term survival rate has progressed to approximately 50%. The therapy used for treatment, however, is very toxic and associated with serious long-term side effects. Treatment for neuroblastoma typically includes chemotherapy, surgery, stem cell transplantation, radiation therapy, and immunotherapy. At the end of this treatment, children with neuroblastoma commonly take the drug isotretinoin for 6 months. Isotretinoin maintains the response to previous treatments and helps turn the remaining cancer cells into normal nerve cells.
Most patients often respond to this treatment at first but are at a high-risk for the cancer coming back. The majority of the children who relapse after treatment or develop recurrent disease do so in the first two years following the completion of therapy and there are no current treatments to cure those who relapse. This study will explore whether or not extending the therapy with isotretinoin from 6 months to 24 months will help prevent the cancer from coming back without causing severe side effects.
Study Overview
Detailed Description
Neuroblastoma is the most common extracranial solid tumor of childhood and accounts for 15% of all pediatric cancer related deaths. The majority of patients present with high-risk disease that is widely metastatic and aggressive. Historically, less than 30% of these patients achieved long-term disease-free survival and the majority of relapses occurred within the first 24 months following treatment. Survival rates have modestly improved with the addition of high-dose chemotherapy and stem cell rescue, radiotherapy, surgery and biologic therapy, yet 50% of patients still succumb to their disease. Current treatment of neuroblastoma also carries significant acute toxicities and those patients that are cured suffer significant long-term treatment-related morbidities. Therefore, children with high-risk neuroblastoma are in need of novel therapeutic strategies that will improve cure rates without adding to acute and long-term toxicities.
Retinoids, derivatives of vitamin A, have been repeatedly shown to arrest cell growth of neuroblastoma cells in vitro by causing differentiation. Clinical trials in relapsed neuroblastoma patients with bulky tumors failed to show significant responses to retinoid therapy. Subsequently, however, a sentinel randomized clinical trial demonstrated that isotretinoin(13-cis-retinoic acid), when given to patients with minimal residual disease following consolidation chemotherapy, independently improved the overall survival of patients with high-risk neuroblastoma. The treatment regimen included isotretinoin for 2 weeks followed by a 2 week rest period for 6 treatment cycles. The treatment was very well tolerated with minimal side effects. The duration of treatment, 6 months, was arbitrarily chosen and currently many institutions implement prolonged retinoic acid treatment in patients with relapsed high-risk disease, yet no formal study has been done to statistically show improved survival with prolonged biotherapy.
To improve the progression-free survival in patients with high-risk neuroblastoma this trial will prolong therapy with isotretinoin to 24 months, the time window in which most relapses occur. The treatment is anticipated to be well tolerated with no increase in adverse side effects based on the benign side effect profile of patients who have received the typical 6 month treatment course. The trial will consist of a single arm of 20 high-risk neuroblastoma patients who will receive a total of 24 cycles of isotretinoin (2 weeks on treatment followed by 2 weeks of rest) compared to the historical and current COG study treatment of 6 cycles. Patients will be accrued over a 3-year period.
The toxicity and tolerability of a prolonged course of isotretinoin biologic therapy will be closely monitored with a focus on neuropsychologic and bone toxicities, and isotretinoin drug levels will be measured to determine if there is a correlation between levels and anti-tumor efficacy or toxicities. This will provide complementary data to support future national cooperative group trials.
