EXPANDED ACCESS

Cellphire Policy: Expanded Access Use of Thrombosomes®

Overview

This Policy regarding Expanded Access to Cellphire’s Investigational New Drug Thrombosomes (TBX), an activated freeze-dried platelet, is aimed at addressing the limited availability of platelets that are the result of the COVID-19 pandemic. Blood products are in critical need during this time frame and blood banks are faced with extremely limited supplies.

In the situation where a patient presents with WHO Grade 3 bleeding or higher and is in critical need of platelet/blood products, this Policy facilitates the use of TBX to treat the acute bleed and possibly mitigate the risk of additional critical bleeding. The benefit of the use of TBX in this critical set of circumstances is believed to outweigh the risks of the use of this investigational product. 

Policy Statements

In cases where a clinical trial with Thrombosomes is not an option, Cellphire may elect to provide the Sponsor/Investigator expanded access to its investigational product, TBX. Treating Sponsor/Investigators and patients should note that clinical safety and efficacy of investigational products has not been fully established, so all potential risks and benefits should be carefully evaluated before seeking expanded access to this product. It is envisioned that requests could be made by Sponsor/Investigators as either an Individual Patient IND or Emergency Use Individual Patient IND. For more information on submitting requests to the FDA, click here.

This policy is aimed at addressing both types of requests. Cellphire will consider requests for access to TBX, according to internal Cellphire SOPs and as permitted by applicable law, in very specific circumstances, when certain criteria are met. For more detailed information, see Cellphire’s full policy here.

Requesting Access

Sponsor/Investigators seeking single patient expanded access (either emergency or non-emergency use) to TBX on behalf of their patient should call Cellphire at 301-545-2528 or submit an inquiry to expandedaccess@cellphire.com.

The request will promptly be addressed, generally within 24 hours of receipt by a member of either the Cellphire Clinical Affairs or Clinical Study Teams. Sponsor/Investigators should provide a written summary of the specific medical circumstances that require single patient expanded access and the need for treatment with TBX which briefly includes responses to each of the eligibility requirements listed above.

It should be noted that there is no guarantee that an expanded access request will be granted by FDA. Sponsor/Investigators who receive a TBX dose for their patients through the expanded access program must comply with all applicable FDA regulations, contractual conditions, safety reporting required by FDA, and protection of intellectual property.

This policy is subject to change. Cellphire will revisit the policy periodically and amend it as appropriate. This policy is not a guarantee of access to any of Cellphire’s investigational products.

The Cellphire Method

Cellphire has developed a proprietary method for the long-term stabilization of blood cells in the dry state. The first application of this technology is to develop a freeze-dried hemostatic agent derived from platelets.
