PassPort Technologies, Inc. Announces Positive Interim Phase I Results of Zolmitriptan Transdermal Microporation System for the Treatment of Acute Migraine | BioSpace

SAN DIEGO, March 29, 2024 /PRNewswire/ — PassPort Technologies, Inc. (PPTI), based in San Diego, a clinical-stage drug and medical device development company, today announced positive interim results from the Phase 1 (Part A) clinical trial of Zolmitriptan PassPort® utilizing its proprietary transdermal microporation system for the treatment of acute migraine. Zolmitriptan is an FDA-approved prescription medication used for treating migraine symptoms.

Zolmitriptan PassPort® demonstrated tolerability and rapid delivery of zolmitriptan.

Zolmitriptan PassPort®, a needle-free combination system consisting of a microporation device and zolmitriptan patch, was applied on the individual’s upper arm to deliver zolmitriptan into the systemic circulation via micropores painlessly created in the skin.

The open-label, randomized, crossover study consisting of 32 healthy volunteers tested the tolerability and pharmacokinetics of Zolmitriptan PassPort® with 3 different doses (0.75 mg, 1.5 mg, and 3.0 mg) compared to oral administration of 2.5 mg zolmitriptan.

Zolmitriptan PassPort® was well-tolerated with no serious adverse events. Zolmitriptan was detected in the plasma only 2 minutes after Zolmitriptan PassPort® administration, much faster than 15 minutes seen for oral administration. The relative bioavailability of Zolmitriptan PassPort® was approximately 160 to 200% compared to oral zolmitriptan.

“We are pleased with the tolerability and pharmacokinetics of Zolmitriptan PassPort® in Phase 1 Part A study. Our Zolmitriptan PassPort® is expected to demonstrate significant advantages of faster onset of action and higher pain relief for migraine patients with severe nausea and patients who are non-responsive to oral triptans. It will provide a Best-in-Class product option.” said President and CEO Tomoyuki Fujisawa.

Part B study, currently underway, will evaluate the transdermal administration of a single dose at alternative sites, the subject’s abdomen and upper thigh. The final results will be available to the public in Q3 2024.

PPTI holds exclusive global rights to develop and commercialize the Zolmitriptan PassPort® but intends to out-license for further clinical development and commercialization.
