Key Q&A

Q:What are the differences in efficacy and safety between the 40 mg and 60 mg doses in Phase I trials?
A:The 60 mg dose showed a clear benefit-risk profile compared to the 40 mg dose. Efficacy, measured by SVR and TSS, was maximized in the 60 mg group. Safety differences were less stark, with slightly higher heme and non-heme toxicities in the 60 mg group. Pharmacokinetic data also showed higher exposures with the 60 mg dose, supporting its selection for Phase III trials.
Q:What are your thoughts on Novartis' recent plans in the myelofibrosis (MF) space?
A:Novartis' plans highlight the importance of selecting the right patient population and the unmet need in the MF market. Novartis may file in the EU, indicating regulatory flexibility there. However, their U.S. trial will take years to read out, giving Karyopharm time to establish its combination therapy as the standard of care in frontline MF.
Q:What is the strategy for eltanexor and other MPNs if MF data is positive?
A:Eltanexor, a second-generation XPO1 inhibitor, has differentiating properties like lower IC50s and better safety. It has shown encouraging preliminary data in other tumors. The strategy is to expand beyond MF to other MPNs like PV and ET, supported by preclinical data. Eltanexor's patent extends to 2034, with potential extensions to 2039.
Q:Has there been any update on blinded safety data or baseline characteristics in the trial?
A:No updates have been made beyond previously disclosed data. Baseline demographics and TSS evolution align with expectations. Blinded safety data will be definitively analyzed next month, with early indications suggesting manageable toxicities and potentially lower Grade 3+ anemia.
Q:What is the dosing protocol for selinexor and ruxolitinib in the trial?
A:Selinexor doses can be reduced from 60 mg to 40 mg to 20 mg, with re-escalation possible. Ruxolitinib dosing follows local labels, typically based on baseline platelet count. Dose modifications depend on the type of adverse event, with ruxolitinib adjusted for hematologic toxicities and selinexor for non-heme toxicities.
Q:What is the purpose of the SENTRY-2 trial, and how does it fit into the broader strategy?
A:SENTRY-2 aims to explore selinexor as a monotherapy and in combination with other JAK inhibitors. It allows flexibility in treatment and could expand selinexor's role in MF and other MPNs. The trial includes patients with platelets ≥50,000 and offers opportunities for label expansion and guideline inclusion.
Q:How do the Phase III baseline characteristics compare to Phase I/II, and what could this mean for efficacy?
A:Phase III patients appear less sick, with higher baseline hemoglobin and milder disease. However, efficacy is expected to remain consistent across subgroups, as seen in Phase I data. The milder population should not impact the ability to demonstrate meaningful benefit.
Q:What feedback have you received from KOLs and regulators on symptomatic improvement thresholds?
A:KOLs prioritize SVR as the primary treatment driver, with symptoms being secondary. They expect some symptom improvement above ruxolitinib. Regulators have not specified a minimum delta for symptoms, but statistical significance in both SVR and TSS is the goal.
Q:What is the frequency of DSMB safety reviews, and would they detect imbalances in transformations?
A:The DSMB reviews safety data every 4-6 months, including all adverse events, SAEs, and transformations. No issues have been reported so far, and the study continues without modification.
Q:What can you say about dose reductions in the SENTRY trial and their comparison to Phase I?
A:Selinexor dose intensity among the first 61 patients was greater than 95%. Ruxolitinib dose reductions are variable and not meaningful to analyze in the context of blinded data. Further insights will come with top-line data.
Q:Where were the first 61 patients in the SENTRY trial recruited from?
A:The first 61 patients were recruited globally, primarily from North America and Europe, with more patients likely from North America due to earlier site activations.
Q:What gives you confidence in hitting the TSS endpoint in the SENTRY study?
A:Phase I data showed strong TSS50 and absolute TSS improvements. Rapid cytokine reductions correlate with symptom improvement. The FDA allowed a switch to absolute TSS without fatigue, a more sensitive measure. The trial's design and patient population also support confidence in achieving the endpoint.
Q:Review of Unclear Management Responses
A:Management avoided directly addressing the specific dose reductions for ruxolitinib in the SENTRY trial, citing variability in starting doses and the blinded nature of the data. They also did not provide a clear timeline for when in March the Phase III data would be released, only stating it would be 'in March.'
