About US Orphan Drug Designation
The US Orphan Drug Designation program provides orphan status to drugs intended to treat rare diseases or disorders that affect fewer than 200,000 people in the US, or that affect more than 200,000 people but are unlikely to recover the costs of developing and marketing the drug. Orphan designation by the
About Soft Tissue Sarcoma
Sarcomas are a group of aggressive cancers of connective tissue of the body for which there are currently limited treatment options. Soft tissue sarcomas are treated with surgery, chemotherapy and radiation. Doxorubicin as a single agent or in combination with ifosfamide are the most commonly used chemotherapeutic regimens in patients with advanced soft tissue sarcoma, but response rates are generally low and toxicity can be significant. The
SARC is a non-profit organization dedicated to the development and support of clinical trial research for the prevention, treatment and cure of sarcomas -- a cancer of the bone and connective tissue of the body. For more information please visit http://sarctrials.org/
TH-302 is a hypoxia-targeted drug that is thought to be activated under tumor hypoxic conditions, a hallmark of many cancer indications. Areas of low oxygen levels (hypoxia) within tissues are common in many solid tumors due to insufficient blood vessel growth. Similarly, the bone marrow of patients with hematological malignancies has also been shown, in some cases, to be extremely hypoxic.
TH-302 has been investigated in over 600 patients in Phase 1/2 clinical trials to date in a broad spectrum of tumor types, both as a monotherapy and in combination with chemotherapy treatments and other targeted cancer drugs. Threshold has several additional ongoing clinical trials, the most advanced of which is a Phase 3 pivotal study evaluating TH-302 in combination with doxorubicin versus doxorubicin alone in patients with soft tissue sarcoma, and recently completed a Phase 2b trial of TH-302 in combination with gemcitabine versus gemcitabine alone in pancreatic cancer. In
Threshold is a biotechnology company focused on the discovery and development of drugs targeting Tumor Hypoxia, the low oxygen condition found in microenvironments of most solid tumors as well as the bone marrows of some hematologic malignancies. This approach offers broad potential to treat a variety of cancers. By selectively targeting tumor cells, we are building a pipeline of drugs that hold promise to be more effective and less toxic to healthy tissues than conventional anticancer drugs.

Except for statements of historical fact, the statements in this press release are forward-looking statements, including statements regarding TH-302's potential ability to treat cancers, planned clinical trials and anticipated results, and potential therapeutic uses and benefits of TH-302. These statements involve risks and uncertainties that can cause actual results to differ materially from those in such forward-looking statements. Potential risks and uncertainties include, but are not limited to, Threshold's ability to enroll or complete its anticipated clinical trials, the time and expense required to conduct such clinical trials and analyze data, whether such trials confirm results from earlier trials and preclinical studies, potential side effects associated with TH-302, issues arising in the regulatory or manufacturing process and the results of such clinical trials (including product safety issues and efficacy results), and Threshold's ability to raise additional capital to continue funding its operations. Further information regarding these and other risks is included under the heading "Risk Factors" in Threshold's Annual Report on Form 10-K, which has been filed with the
