'With strong support from leading healthcare-dedicated investors, Palvella is well positioned to enter the public markets and pursue our vision of becoming the leading rare disease company focused on developing and commercializing novel therapies to treat patients suffering from serious, rare genetic skin diseases,' said
Concurrent with the merger, Palvella completed a previously announced oversubscribed
Palvella's research team developed QTORIN, a patented and versatile platform designed to generate novel topical therapies that penetrate the deep layers of the skin to locally treat a broad spectrum of serious, rare genetic skin diseases. Well-accepted mechanisms of action of rapamycin and other therapeutic agents represent potential therapies for rare genetic skin diseases. However, the adverse event profile of those agents through systemic exposure poses significant barriers to patient adoption. Palvella's QTORIN product candidates are designed for targeted, localized delivery of therapeutic agents to pathogenic tissue of interest while minimizing systemic absorption and thereby reducing the risk of unwanted adverse events associated with systemic therapy.
Palvella's lead product candidate QTORIN rapamycin is a novel, patented 3.9% rapamycin anhydrous gel currently under development for the treatment of microcystic LMs, cutaneous VMs, and other serious, functionally debilitating skin diseases driven by the overactivation of the mammalian target of rapamycin (mTOR) pathway. QTORIN rapamycin has received FDA Breakthrough Therapy Designation, Fast Track Designation, and Orphan Drug Designation for microcystic LMs and is the recent recipient of up to a
In the third quarter of 2024, Palvella initiated SELVA, a 24-week, Phase 3, single-arm, baseline-controlled clinical trial of QTORIN rapamycin administered once daily for the treatment of microcystic LMs. The primary efficacy endpoint is the change from baseline in the overall microcystic LM Investigator Global Assessment (mLM-IGA) at week 24. The Phase 3 study is enrolling approximately 40 subjects, age six or older, at leading vascular anomaly centers across the
Transaction Details
Based on the final exchange ratio of approximately 0.30946 shares of Pieris common stock for each share of Palvella common stock, at the closing of the merger, there are approximately 13.95 million shares of the combined company's common stock outstanding on a diluted basis, with prior Pieris stockholders owning approximately 11% on a diluted basis and prior Palvella stockholders (including investors in the private placement) holding approximately 89% of the combined company's outstanding common stock on a diluted basis.

Holders of the CVR will be entitled to receive payments from proceeds received by the combined company, if any, under Pieris' existing partnership agreements with
About Microcystic Lymphatic Malformations
Microcystic LMs are a rare, chronically debilitating genetic disease caused by dysregulation of the phosphatidylinositol 3-kinase (PI3K)/mTOR pathway. The disease is characterized by malformed lymphatic vessels that protrude through the skin and persistently leak lymph fluid (lymphorrhea) and bleed, often leading to recurrent serious infections and cellulitis that can cause hospitalization. The natural history of microcystic LMs are persistent and progressive without spontaneous resolution, with symptoms generally worsening during life, including increases in the number and size of malformed vessels that lead to complications and lifetime morbidity. There are currently no FDA-approved treatments for the estimated more than 30,000 diagnosed patients with microcystic LMs in

Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not guarantees of future performance. Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including, without limitation: the limited operating history of each company; the significant net losses incurred since inception; the ability to raise additional capital to finance operations; the ability to advance product candidates through preclinical and clinical development; the ability to obtain regulatory approval for, and ultimately commercialize, Palvella's product candidates, including QTORIN rapamycin; the outcome of early clinical trials for Palvella's product candidates, including the ability of those trials to satisfy relevant governmental or regulatory requirements; the fact that data and results from clinical studies may not necessarily be indicative of future results; Palvella's limited experience in designing clinical trials and lack of experience in conducting clinical trials; the ability to identify and pivot to other programs, product candidates, or indications that may be more profitable or successful than Palvella's current product candidates; the substantial competition Palvella faces in discovering, developing, or commercializing products; the negative impacts of the global events on operations, including ongoing and planned clinical trials and ongoing and planned preclinical studies; the ability to attract, hire, and retain skilled executive officers and employees; the ability of Palvella and Pieris to protect their respective intellectual property and proprietary technologies; reliance on third parties, contract manufacturers, and contract research organizations.
