Abstract:
ONC201 is an oral selective antagonist of the dopamine D2 receptor and direct activator of caseinolytic protease P. In a phase II study, ONC021 was shown to be well tolerated with notable efficacy in patients with the rare neuroendocrine neoplasms pheochromocytomas-paragangliomas, although biomarkers for activity remain to be elucidated. See related article by Anderson et al., p. 1773.
Insights
ONC201, an oral drug, shows promise for treating rare pheochromocytomas-paragangliomas. This phase II study found it well-tolerated with notable efficacy, though further research is needed for activity biomarkers.
Area of Science:
- Pharmacology
- Oncology
- Neuroendocrinology
Background:
- ONC201 is an oral selective dopamine D2 receptor antagonist and caseinolytic protease P activator.
- A phase II study investigated ONC201 in patients with pheochromocytomas-paragangliomas, a type of rare neuroendocrine neoplasm.
Discussion:
- The study demonstrated that ONC201 was well-tolerated in patients.
- Notable efficacy was observed in the treatment of pheochromocytomas-paragangliomas.
- Biomarkers for ONC201 activity in this patient population require further elucidation.
Key Insights:
- ONC201 exhibits therapeutic potential for rare neuroendocrine neoplasms.
- The drug is orally administered and shows a favorable safety profile.
- Further investigation is necessary to identify predictive biomarkers for treatment response.
Outlook:
- Future research should focus on identifying biomarkers to personalize ONC201 treatment.
- Expanding clinical trials may confirm the efficacy and safety of ONC201 in a larger patient cohort.
- ONC201 could represent a novel therapeutic option for patients with limited treatment alternatives.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
