JV makes ‘stability timer’ logistics tech to protect cell and gene therapies

The US Patent and Trademark Office has granted a notice of allowance for ‘shelf life’ timer technology used to protect time-sensitive biologic materials in transit.

BioLife Solutions and Savsu Technologies said the technology will be incorporated into Savsu’s evo.is cold chain software offering. The patent – to be issued on April 10, 2018 – covers Biologic stability, delivery logistics and administration of time and/or temperature sensitive biologic based materials​ (9,939,422 and 9,939,423).

The US-headquartered firms formed a joint venture (JV) in 2014 to develop precision thermal shipping containers under Savsu’s evo brand.

A Savsu spokesperson told us the patent covers a payload “stability timer” – also known as a “shelf life” timer in the evo.is cold chain offering – to help transport and protect high value payloads, such as cell and gene therapies.

The timer tracks the remaining stability time and informs clinicians and relevant parties via a messaging system. 

“Manufactured, personalized cell therapy doses are temperature- and time-sensitive payloads that must be administered to the patient within a validated stability period or shelf life,” ​the spokesperson explained.

It is easy for busy employees in hospital receiving areas to set aside or overlook a package that has a time sensitive payload, the spokesperson told us.

However, in the event of a delay in transit, the timer provides a “helpful reminder,” ​so that “all parties can evaluate the situation and possible corrective actions in relation to the time left on the timer.”

Pack-out errors

The patent also detects cold packs and the biologic payload container to help reduce pack-out errors.

“Alerting pack-out technicians that the shipping container is not packed out correctly could mean the difference between a cancer patient being administered a viable CAR T-cell therapy vs. receiving cells that were dead on arrival,” ​said the spokesperson.

The joint venture has received two USPTO patients to date and has 11 additional patent applications pending, covering hardware and software.
