Modeyso (dordaviprone)

The drug is administered orally once weekly and is well tolerated. Dordaviprone offers a new targeted systemic therapy for DMG with proven safety, good tolerability, and meaningful clinical benefit.

The recent ONC201 FDA approval, however, suggests DIPG therapy is tractable...A proof-of-concept in vivo mouse xenograft experiment demonstrated a reduction in tumor volume beyond antibody treatment alone. The work here represents an important milestone in preclinical development of a novel deruxtecan-based ADC agent for an intractable pediatric brain cancer, concurrent with other ADC agents demonstrating real-world clinical efficacy and gaining approvals in multiple disease indications.

DU145 and PC3 AIPC cells were treated with ONC201 (parent compound), ONC206, or ONC212...Imipridones induced a time-dependent cell-cycle redistribution with increased sub-G1 accumulation and modulated mitochondrial membrane potential and mass in a context-dependent manner. Collectively, these findings position ONC212 as a leading imipridone candidate in AIPC models, combining potent inhibition of tumor and stem-like cell functions with a coherent stress-response signature that supports further translational evaluation.

These studies implicate mitochondrial biogenesis as a biomarker of imipridone resistance and a focus for the development of combinatorial strategies to provide effective therapeutic options for a challenging pediatric brain tumor.

Among these are histone deacetylase inhibitors (HDACis), receptor tyrosine kinase inhibitors, and novel agents such as ONC201 and unesbulin that target metabolic and epigenetic pathways respectively...Despite these advances, challenges such as drug delivery across the blood-brain barrier and therapeutic resistance persist, necessitating the development of combination therapies and innovative delivery methods. Ongoing research is focused on refining these strategies and exploring additional molecular and immunological targets to improve outcomes for children with DMG.

Ovarian cancer has a poor clinical prognosis due to chemoresistance following carboplatin/paclitaxel treatment...The therapeutic efficacy of these combinations was also proved in patient-derived tumor organoid models (PDTO), leading to their structural disintegration and reduced viability. Collectively, our study highlights that ABT-737, through BCL-xL inhibition and synergy with ER stress inducers, triggers ovarian cancer death, offering promising strategies for overcoming chemoresistance in relapsed ovarian cancer.

To overcome this issue, herein, we developed a cobalt-pheophytin (CoPheo) coordination micelle chelating two chemotherapeutic agents including ONC201 and Palbociclib (Pal), yielding CoPheo-ONC201-Pal-F127. In addition, ONC201-mediated mitogen-activated protein kinase kinase (MEK) inhibition, combined with Pal-induced CDK4/6 blockade, promotes cellular senescence and remodels the tumor microenvironment. These three independent mechanisms collectively establish a mutually enhanced therapeutic strategy capable of overcoming the complex drug resistance driven by multiple downstream signaling pathways in KRAS-mutant pancreatic cancer.

Our results highlight ONC206 as a novel therapeutic option for patients with high-risk medulloblastoma and provide strong rationale for testing the efficacy of ONC206 in the treatment of these patients.

The individualized regimen comprised trametinib and everolimus for dual pathway inhibition, the tissue-agnostic agent dordaviprone (ONC201), metabolic modulation with 2-deoxy-D-glucose, and electric field-based therapy. The systematic integration of comprehensive molecular profiling with mechanistically rational treatment selection may contribute to meaningful radiological and clinical benefit in this otherwise uniformly fatal disease. These observations support further investigation of individualized, pathway-targeted approaches in prospective studies and N-of-1 trial frameworks.
