Healthcare Industry News: Zalviso
News Release - September 26, 2014
AcelRx Pharmaceuticals Provides Regulatory Update on Zalviso(TM)REDWOOD CITY, Calif., Sept. 26, 2014 -- (Healthcare Sales & Marketing Network) -- AcelRx Pharmaceuticals, Inc. (ACRX), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute and breakthrough pain, today provided an update on the plans for the resubmission of the Company's New Drug Application (NDA) for Zalviso™ (sufentanil sublingual tablet system). The Company recently held a teleconference with representatives from the Food and Drug Administration (FDA) to review the Company's proposed response to the Zalviso Complete Response Letter (CRL) received on July 25, 2014. The Company had submitted a Briefing Document to the FDA ahead of the teleconference and received preliminary comments from the FDA on the Briefing Document. Based on the communications with the FDA, subject to the timing of the FDA review and comment on protocols to be submitted for the bench testing and Human Factors Study, the Company is targeting resubmission of the Zalviso NDA in the first quarter of 2015. However, depending on feedback from the FDA, the timing of the filing of the NDA could be later than the first quarter of 2015. The FDA also communicated that the planned resubmission will qualify as a Class 2 resubmission with a review period of six months.
During the teleconference with the FDA, the Company discussed the items included in the CRL, specifically: testing of the proposed mitigations to reduce the incidence of optical system errors, changes to the Instructions for Use (IFU) for the Zalviso System to address risk of inadvertent misplacement of tablets, and submission of additional data to support the shelf life of the product.
As a result of the communications, the Company confirmed that bench testing would be an acceptable approach to evaluate the reduction in optical system errors. The protocol for the bench testing will be submitted to the FDA for review and comment.
To address the risk of inadvertent misplacement of tablets, the Company proposed mitigations through the Zalviso System and IFU and to test these mitigations by way of a Human Factors Study. The protocol for the Human Factors Study will be submitted to the FDA for review and comment. The FDA stated that the adequacy of the Human Factors Study and the results of the study will be subject to final review and approval by the FDA.
Lastly, the Company proposed including additional stability data in the resubmission to support the proposed 24 month shelf life of the Zalviso System. The FDA has agreed with this approach subject to review of the data previously submitted and to be submitted.
"The discussion with the FDA was productive," said Richard King, president and CEO of AcelRx. "Over the coming months we will prepare, submit and finalize with the FDA the protocols required to complete this work. Assuming timely review by the FDA on the protocols, we anticipate being able to complete the work with a target to refile the Zalviso NDA in the first quarter of 2015. However, depending on feedback from the FDA, the timing of the filing of the NDA could be later than the first quarter of 2015."
The Company awaits receipt of the teleconference meeting minutes from the FDA to confirm the target timelines discussed above.
