Rhea-AI Summary
Orphazyme has received encouraging feedback from the FDA following a Type A meeting regarding arimoclomol, a treatment for Niemann-Pick disease Type C (NPC). The FDA suggests that Orphazyme provide supplementary data and analyses to support its resubmission path after a previous Complete Response Letter indicated the need for more evidence regarding the drug’s efficacy. CytRx Corporation, which sold arimoclomol to Orphazyme, expressed optimism about the FDA’s invitation for further discussions and potential regulatory pathways.
Positive
FDA encourages Orphazyme to submit additional data for arimoclomol.
The FDA supports removing the cognition domain from the NPC Clinical Severity Scale endpoint.
Future engagements with the FDA could streamline the resubmission process.
Negative
Initial Complete Response Letter from the FDA requires additional evidence for approval.
Additional clinical data is needed to support the NDA benefit-risk assessment.
FDA Recommends Orphazyme Provides Supplemental Information and Analyses
FDA Offers to have Further Interactions with Orphazyme to Identify Path to Resubmission for Arimoclomol in NPC
LOS ANGELES--(BUSINESS WIRE)--
CytRx Corporation (OTCQB: CYTR) (“CytRx” or the “Company”), a specialized biopharmaceutical company focused on research and development for the oncology and neurodegenerative disease categories, today commented on Orphazyme A/S's (NASDAQ: ORPH) ("Orphazyme") encouraging regulatory update following its recently held Type A meeting with the U.S. Food and Drug Administration ("FDA") on arimoclomol, a heat shock protein amplifier intended for the treatment of Niemann-Pick disease Type C (“NPC”). Arimoclomol, CytRx's drug candidate, was sold to Orphazyme in exchange for milestone payments and royalties.
In June 2021, Orphazyme announced it had received a Complete Response Letter ("CRL") from the FDA following the regulatory agency's review of the new drug application ("NDA") for arimoclomol. Orphazyme disclosed that the FDA issued the CRL based on needing additional evidence to further substantiate the validity and interpretation of the 5-domain NPC Clinical Severity Scale and, in particular, the swallow domain. Further, the FDA noted in the CRL that additional data is needed to bolster confirmatory evidence beyond the single phase 2/3 clinical trial to support the benefit-risk assessment of the NDA.
Orphazyme's recent Type A meeting to discuss the CRL resulted in the following takeaways:
The FDA recommended that Orphazyme submit additional data, information and analyses to address certain topics in the CRL and engage in further interactions with the FDA to identify a pathway to resubmission.
The FDA concurred with Orphazyme's proposal to remove the cognition domain from the NPCCSS endpoint, with the result that the primary endpoint is permitted to be recalculated using the 4-domain NPCCSS, subject to the submission of additional requested information which Orphazyme intends to provide. To bolster the confirmatory evidence already submitted, the FDA affirmed that it would require additional in vivo or pharmacodynamic (PD)/pharmacokinetic (PK) data; Orphazyme is considering the optimal path forward to address the FDA’s requests.
Christophe Bourdon, Chief Executive Officer of Orphazyme A/S, commented:
“We are pleased to have gained a greater understanding from the FDA on the information that could address topics in the CRL. This is good progress. We are encouraged by the FDA’s request to submit additional information and the invitation to further engage to discuss our approach and potential path forward. While we have not yet established a path to resubmission, our team will now work on putting a plan in place to discuss with the FDA during our next interactions and we will share more details about our strategy as and when appropriate. We firmly believe in the establishment of a positive benefit-risk balance for arimoclomol and will continue to support the NPC community and our early access programs.”
Steven A. Kriegsman, Chairman and Chief Executive Officer of CytRx, commented:
"We are highly encouraged by the outcome of Orphazyme's recent meeting with the FDA on arimoclomol in Niemann-Pick disease Type C. It's especially impactful to hear that the FDA welcomed the submission of additional information and invited Orphazyme to engage further with the agency in order to identify a path toward resubmission of an NDA. We look forward to monitoring additional developments in the U.S. as well as Orphazyme's pursuit of European regulatory approval for arimoclomol in Q1 2022."
