PHASE 3 STELLAR STUDY SHOWS EFLORNITHINE IMPROVES OVERALL SURVIVAL (OS) AND PROGRESSION FREE SURVIVAL (PFS) IN PATIENTS WITH RECURRENT 2021 WHO ASTROCYTOMA, IDH-MUTANT GRADE 3 (SNO 2024) - "STELLAR was a phase III randomized, open-label trial of eflornithine (ornithine decarboxylase inhibitor) with lomustine versus lomustine alone, originally for patients with recurrent AA. However, as the WHO definition of AA evolved during trial conduct (e.g., excluding IDH wild-type disease), we determined results in both the original ITT population and by revised molecularly defined WHO 2021 diagnoses in pre-planned analyses .METHOD Key eligibility: age ≥ 18, AA (2016 WHO criteria), first recurrence ≥ 6 months after radiation and temozolomide, KPS ≥ 70, no imaging findings consistent with grade 4 glioblastoma...CONCLUSION There was no difference in OS between arms in the ITT analysis. However, medically meaningful and statistically significant OS and PFS benefits were observed with eflornithine in the pre-planned analysis of patients with molecularly defined 2021 WHO CNS grade 3 astrocytoma."

Combination of Eflornithine and Lomustine Demonstrates Clinically Meaningful Improvements in Overall Survival (OS) and Progression Free Survival (PFS) in Patients with Recurrent Astrocytoma, IDH Mutant Grade 3 (GlobeNewswire) - P3 | N=343 | STELLAR (NCT02796261) | Sponsor: Orbus Therapeutics, Inc. | "The primary efficacy endpoint, overall survival (OS) in the intention-to-treat population of 343 patients had a hazard ratio (HR) = 0.94 and was not statistically significant; In the 194 patients with recurrent grade 3 IDH mutant astrocytoma, clinically meaningful improvements in both OS and PFS were observed; Median OS in the eflornithine + lomustine arm was 34.9 months compared to 23.5 months in the lomustine alone arm with HR = 0.64 (log rank p = 0.016); PFS showed a correlating benefit with median PFS of 15.8 months in the eflornithine + lomustine arm and 7.2 months in the lomustine alone arm with HR = 0.58 (log rank p = 0.015); The combination of eflornithine and lomustine was generally well-tolerated....The results from the Phase 3 STELLAR study will be presented at an upcoming medical conference."

Amgen and US WorldMeds: A Tale of Data and Two FDA Adcomm Meetings (BioSpace) - "Despite the lack of a randomized controlled trial for US WorldMeds’ investigational drug, the FDA’s Oncologic Drugs Advisory Committee in a potentially precedent-setting decision found that the company provided adequate data to support its benefit in high-risk neuroblastoma. In a 14-6 vote, the adcomm determined that US WorldMeds provided enough evidence from a Phase II study to conclude that eflornithine hydrochloride (DFMO) boosts event-free survival in its target pediatric patient population."

Effect of eflornithine on mutation frequency in temozolomide-treated U87MG cells. (PubMed, Oncotarget) - "The current chemotherapy options include nitrosoureas (e.g., lomustine) and the imidazotetrazine-class monofunctional DNA alkylating agent, temozolomide (TMZ). It was shown that TMZ significantly increased the frequency of mutations in U87MG glioblastoma cells while DFMO-treated cells showed mutation frequency statistically similar to that of the untreated cells on the respective treatment days. The findings of this study provide evidence to support the hypothesis that DFMO may inhibit progression of DNA mutations caused by alkylating chemotherapy agents, such as TMZ."

[VIRTUAL] Sulindac and Eflornithine Combination Delays the Need for Lower Gastrointestinal Surgery in Familial Adenomatous Polyposis: CPP FAP-310 Trial (ACG 2020) - "A total of 158 patients in the CPP FAP-310 trial fit the criteria for this LGI disease progression assessment. FAP disease progression was observed in 2/54 (3.7%), 9/53 (17.0%), and 10/51 (19.6%) patients in the combination, sulindac, and eflornithine arms, respectively, corresponding to risk reductions of 80% (hazard ratio [HR]=0.20; 95% CI: 0.05-0.80; p=0.02) and 83% (HR=0.17; 95%CI: 0.04-0.70; p=0.01) between combination and sulindac alone or eflornithine alone, respectively (Figure). The need for surgery as determined by the endoscopist occurred in 0, 7 (13.2%), and 8 (15.7%) patients in the combination, sulindac, and eflornithine arms, respectively, corresponding to risk reductions approaching 100% both between the combination and sulindac arms (HR=0.00; 95%CI: 0.00-0.48; p=0.005) and between the combination and eflornithine arms (HR=0.00; 95%CI: 0.00-0.44; p=0.003)."
