SciClone and Taiwan Liposome Company Enter Into a Licensing Agreement for ProFlow, a Novel Treatment for Peripheral Arterial Disease for the China Market

FOSTER CITY, CA and TAIPEI CITY, TAIWAN--(Marketwired - Jun 25, 2013) - SciClone Pharmaceuticals, Inc. (NASDAQ: SCLN) today announced that the Company has entered into an agreement with Taiwan Liposome Company (TLC) granting SciClone a license and the exclusive rights in China, Hong Kong and Macau to promote, market, distribute and sell ProFlow® for the treatment of peripheral arterial disease (PAD) and other indications.

ProFlow is a novel lipid emulsion-based formulation of prostaglandin E1 (PGE1), a vasodilator and platelet inhibitor. TLC's proprietary lipid-based delivery systems (LDDS) are designed to modify and broaden the use of existing drugs and enhance their therapeutic index. ProFlow has demonstrated to have twice the shelf life as currently marketed lipid emulsion formulations of PGE1. A patent providing broad protection for ProFlow has been granted in China, Japan and Taiwan. TLC has also applied for worldwide composition of matter patents.

Peripheral arterial disease is a serious cardiovascular condition in which blood flow to the limbs (usually the legs) is restricted due to arterial plaque build-up. PAD can cause severe pain and restricted mobility, and potentially life-threatening blood clots. PAD represents a large and growing market opportunity in China. The current market leading drug generates annual revenue of more than $200 million.

Commented Friedhelm Blobel, Ph.D., SciClone's Chief Executive Officer: "We are excited to add ProFlow to our product portfolio, as the cardiovascular market represents a large and growing commercial opportunity for which SciClone is well-positioned. We can leverage our considerable sales and marketing expertise for this product. We believe that ProFlow has significant therapeutic and commercial advantages that differentiate it from other branded and generic competitors in the expanding PAD segment. We look forward to working with our partner TLC to bring this important medical advance to patients in need."

"China is becoming an increasingly prominent market, and we are very pleased to be working with a NASDAQ company that has a strong presence in China, such as SciClone," said Dr. Keelung Hong, Chairman and Chief Executive Officer of TLC. "SciClone was ranked number 39 in Fortune's 2012 Fastest-Growing Companies, which makes it an ideal partner for such a rapidly growing market like China, and also a perfect strategic fit for TLC, since we share the same enthusiasm and sense of urgency for bringing important new therapeutics to patients."

Under the terms of the agreement, TLC will be responsible for the continued development, including potential clinical trials and regulatory activities, as well as the manufacturing and supply of ProFlow, and SciClone will be responsible for all aspects of commercialization, including pre- and post-launch activities. ProFlow has been submitted to the China Food and Drug Administration (CFDA) for approval, and it is expected that some additional clinical testing may be required prior to approval. Financial terms of the agreement include clinical, regulatory and sales milestone payments up to an aggregate of $39.5 million. The agreement provides for the principal terms of the arrangement between SciClone and TLC, and the companies have agreed to negotiate a supplemental license and supply agreement.
