Threshold Pharmaceuticals Reports Second Quarter Financial Results

-- Presented additional subset data at ASCO from Phase 3 MAESTRO trial of evofosfamide in pancreatic cancer; meaningful improvement in overall survival in patients from Asia --

SOUTH SAN FRANCISCO, Calif., Aug. 01, 2016 (GLOBE NEWSWIRE) -- Threshold Pharmaceuticals, Inc. (Nasdaq:THLD), a clinical-stage biopharmaceutical company developing novel therapies for cancer, today reported financial results for the second quarter ended June 30, 2016 and provided an update on the Company's corporate and clinical development activities.

"Encouraged by the MAESTRO data presented recently at ASCO that demonstrated meaningful improvement in overall survival in the subgroup of patients from Japan and South Korea, we are pursuing a registration strategy for Japan," said Barry Selick, Ph.D., Chief Executive Officer of Threshold. "We have also been encouraged by the translational data evaluating the role of hypoxia in mediating treatment resistance to cancer immunotherapy conducted by collaborators at the MD Anderson Cancer Center and to initiating a clinical trial evaluating evofosfamide in combination with checkpoint blockade."

Recent Highlights
Evofosfamide - The Company's lead product candidate is an investigational hypoxia-activated prodrug that is designed to be activated under tumor hypoxic conditions, a hallmark of many cancers.

Tarloxotinib - Beyond the evofosfamide program, the Company is pursuing the Phase 2 proof of concept studies with tarloxotinib, a hypoxia-activated epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), which is designed to selectively release an irreversible EGFR-TKI in hypoxic tumors.

Second Quarter 2016 Financial Results

About Evofosfamide
Evofosfamide (previously known as TH-302) is an investigational hypoxia-activated prodrug of a bis-alkylating agent that is preferentially activated under severe hypoxic tumor conditions, a feature of many solid tumors. Areas of low oxygen levels (hypoxia) in solid tumors are due to insufficient blood vessel supply. Similarly, the bone marrow of patients with hematological malignancies has also been shown, in some cases, to be severely hypoxic. On December 6, 2015, the Company announced the outcomes of two Phase 3 studies (MAESTRO and TH-CR-406/SARC021) of evofosfamide stating that neither study met its primary endpoint. 

About Tarloxotinib Bromide
Tarloxotinib bromide (the proposed International Nonproprietary Name, previously known as TH-4000), or "tarloxotinib", is a prodrug designed to selectively release a covalent (irreversible) EGFR tyrosine kinase inhibitor under severe hypoxia, a feature of many solid tumors. Accordingly, tarloxotinib has the potential to effectively shut down aberrant EGFR signaling in a tumor-selective manner, thus potentially avoiding or reducing the systemic side effects associated with currently available EGFR tyrosine kinase inhibitors. Tarloxotinib is currently being evaluated in two Phase 2 proof-of-concept trials: one for the treatment of patients with mutant EGFR-positive, T790M-negative advanced non-small cell lung cancer progressing on an EGFR tyrosine kinase inhibitor, and the other for patients with recurrent or metastatic squamous cell carcinomas of the head and neck or skin. Threshold licensed exclusive worldwide rights to tarloxotinib from the University of Auckland, New Zealand, in September 2014

About Threshold Pharmaceuticals
Threshold is a clinical-stage biopharmaceutical company focused on the discovery and development of drugs and diagnostic agents 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.

Forward-Looking Statements
Except for statements of historical fact, the statements in this press release are forward-looking statements, including all statements regarding anticipated development activities and clinical development outlooks related to company-sponsored clinical trials for evofosfamide and tarloxotinib, including potential development opportunities for evofosfamide, including the potential for Threshold's evofosfamide Phase 3 clinical trial to support registration for the treatment of patients with advanced pancreatic cancer in Japan in view that the FDA recently considered the MAESTRO data insufficient to support registration in the U.S., the varying interpretations of the MAESTRO data which could prevent registration; and even if approved, the reduced commercial potential of evofosfamide, if only approved in Japan; the timing of the Phase 2 proof of concept study of tarloxotinib, its therapeutic potential; and Threshold's ability to advance development of evofosfamide and tarloxotinib without establishing new collaborations for our product candidates and otherwise raise substantial additional capital. 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: the ability of Threshold to establish collaborations for our product candidates or otherwise raise substantial additional capital and even if we are successful in raising the additional capital necessary, Threshold's ability to advance the development of its product candidates; Threshold's dependence on the transfer of development activities from Merck KGaA, Darmstadt, Germany, including its dependence on decisions by Merck KGaA, Darmstadt, Germany regarding the amount and timing of resource expenditures for the transfer  of evofosfamide development activities and the risk of potential disagreements with Merck KGaA, Darmstadt, Germany, regarding the time and expense required to transfer clinical trials and analyze data; the uncertainty of clinical success and regulatory approval; the risk that later analysis may not confirm the results of earlier analysis; the risks that the design of, or data collected from, the Phase 3 clinical trials of evofosfamide may be inadequate to demonstrate safety and efficacy, or otherwise may be insufficient to support any marketing authorization submissions and/or regulatory approvals, that evofosfamide may not receive any marketing approvals in a timely manner or at all; issues arising in the regulatory process and the results of such clinical trials (including product safety issues and efficacy results); dependence of Threshold on single source suppliers, including the risk that these single source suppliers may be unable to meet clinical supply demands for evofosfamide and/or tarloxotinib which could significantly delay the development of evofosfamide and/or tarloxotinib; Threshold's ability to enroll or complete tarloxotinib clinical trials, including the ability of Threshold to complete the ongoing clinical trials in the expected timeframe or at all; the risks that Threshold's evaluation of tarloxotinib is at an early stage and it is possible that tarloxotinib may not be found to be safe or effective in the Phase 2 proof-of-concept study of tarloxotinib or in any other studies of tarloxotinib that Threshold may conduct, and that Threshold may otherwise fail to realize the anticipated benefits of its licensing of this product candidate; the amount and timing of licensing fees, milestone payments and royalty payments that we are obligated to pay; and Threshold's need for and the availability of resources to develop evofosfamide and tarloxotinib and to support Threshold's 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 was filed with the Securities and Exchange Commission on March 10, 2016 and is available from the SEC's website ( and on our website ( under the heading "Investors". We undertake no duty to update any forward-looking statement made in this news release.
