Australian researchers have uncovered something remarkable hiding in plain sight. A medication already approved for other uses might hold the key to halting neuroblastoma, an aggressive cancer that strikes young children when they should be playing in sandpits rather than fighting for their lives.
The findings emerged from Children’s Cancer Institute research, where scientists discovered that a repurposed pharmaceutical agent demonstrated significant potential against this devastating childhood disease. Neuroblastoma accounts for roughly 15% of all paediatric cancer deaths despite representing only 6% of childhood cancer cases.
Why This Discovery Matters
Neuroblastoma typically develops in nerve tissue and primarily affects children under five years old. The cancer often appears in the adrenal glands but can emerge anywhere along the sympathetic nervous system.

Current treatment protocols involve:
- Intensive chemotherapy regimens
- Surgical removal of tumours
- Radiation therapy
- Stem cell transplants in severe cases
Yet survival rates for high-risk neuroblastoma remain stubbornly low at around 50%, even with these aggressive interventions.
The research team identified that this existing drug neuroblastoma treatment approach could disrupt the cancer’s ability to thrive and spread. Unlike developing entirely new medications, which takes years and costs billions, repurposing proven drugs accelerates the pathway to clinical application.
How the Research Unfolded
Scientists examined how neuroblastoma cells resist conventional treatments. They found specific molecular pathways that fuel cancer growth, then screened existing medications to identify compounds that could interrupt these processes.
The drug candidate emerged from analysing thousands of approved medications. Laboratory testing revealed it could effectively target neuroblastoma cells whilst sparing healthy tissue, a crucial distinction that reduces treatment side effects.
Early laboratory results showed the medication suppressed tumour growth in cellular models. Further testing in preclinical settings confirmed these promising initial observations.
Professor Glenn Marshall, who leads the Children’s Cancer Institute’s Clinical Studies Unit, explained that identifying existing medications with anti-cancer properties offers multiple advantages. Established safety profiles mean researchers already understand potential side effects, whilst manufacturing processes and dosing guidelines exist from previous applications.

What Happens Next
Moving from laboratory bench to bedside requires methodical progression through clinical trial phases. The research team plans to initiate a childhood neuroblastoma drug trial examining safety and efficacy in paediatric patients.
Phase 1 trials will assess appropriate dosing levels and monitor for adverse reactions. If results prove favourable, Phase 2 studies will evaluate how effectively the treatment combats neuroblastoma compared to standard therapies.
This systematic approach protects young participants whilst gathering essential data about treatment effectiveness. Researchers estimate preliminary results could emerge within 18 to 24 months of trial commencement.
The Broader Impact
Australia loses approximately 40 children annually to neuroblastoma. Globally, thousands of families face this diagnosis each year, making advances in treatment critically important.
Beyond neuroblastoma, the research methodology demonstrates how existing pharmaceutical libraries offer untapped potential for treating various cancers. Scientists worldwide increasingly examine approved drugs for new applications, a strategy called drug repurposing that could accelerate treatment development across multiple diseases.
The Children’s Cancer Institute receives support from various organisations including the Australian Government through the National Health and Medical Research Council. This funding enables researchers to pursue innovative approaches that might not attract commercial pharmaceutical investment.
Current Treatment Landscape
Neuroblastoma treatment intensity depends on several factors:
- Patient age at diagnosis
- Tumour location and size
- Whether cancer has metastasised
- Specific genetic markers present in cancer cells
Children with low-risk neuroblastoma sometimes require minimal intervention, as some tumours regress spontaneously. However, high-risk cases demand aggressive multi-modal treatment that severely impacts quality of life.
Treatment-related complications include hearing loss, growth delays, secondary cancers decades later, and psychological effects from prolonged hospitalisation. Finding gentler yet effective therapies remains a priority for paediatric oncology.

Looking Forward
Whilst cautious optimism surrounds these findings, researchers emphasise that extensive testing lies ahead before this becomes standard treatment. The drug must prove both safe and effective in human trials before regulatory approval.
Families affected by neuroblastoma have reason for hope, though patience remains essential as the scientific process unfolds. Each step brings researchers closer to better outcomes for children facing this formidable disease.
The research underscores Australia’s significant contributions to paediatric cancer research despite our relatively small population. Collaboration between institutions, clinicians, and research scientists continues driving progress against childhood cancers.
For families navigating neuroblastoma diagnosis, staying informed about emerging research offers reassurance that dedicated teams worldwide work tirelessly toward improved treatments. This latest development represents another step forward in that ongoing mission.
