Threshold Pharmaceuticals and Merck KGaA Announce Global Agreement to Co-Develop and Commercialize Phase 3 Hypoxia-Targeted Drug TH-302* Threshold to receive $25 million upfront, plus further potential milestones and royalties
* Deal provides Threshold option to co-commercialize in the United States
* Phase 3 trial in soft tissue sarcoma on-going and randomized Phase II trial in patients with pancreatic cancer expected to report in February 2012
SOUTH SAN FRANCISCO, CA--(Healthcare Sales & Marketing Network)- Threshold Pharmaceuticals, Inc (NASDAQ: THLD ) Threshold Pharmaceuticals, Inc (NASDAQ: THLD ) today announced that a global agreement was signed with Merck KGaA, Darmstadt, Germany, to co-develop and commercialize TH-302, Threshold's small molecule hypoxia-targeted drug. TH-302 is currently being investigated in a global Phase 3 clinical trial in patients with soft tissue sarcoma, a randomized Phase 2 trial in patients with advanced pancreatic cancer from which top-line results are expected in February, as well as additional clinical studies in other solid tumors and hematological malignancies.
Under the terms of the agreement, Merck will receive co-development rights, exclusive global commercialization rights and will provide Threshold an option to co-commercialize the therapeutic in the United States. In exchange, Threshold will receive an upfront payment of $25 million and could receive up to $35 million in additional development milestones during 2012. Threshold is also eligible to receive a $20 million milestone payment based on positive results from its randomized Phase 2 trial in pancreatic cancer. Total potential milestone payments are $525 million, comprised of $280 million in regulatory and development milestones and $245 million in sales-based milestones.
In the United States, Threshold will have primary responsibility for development of TH-302 in the soft tissue sarcoma indication. Threshold and Merck KGaA will jointly develop TH-302 in all other cancer indications being pursued. Merck KGaA will pay 70% of worldwide development costs for TH-302.
Subject to FDA approval in the United States, Merck KGaA will initially be responsible for commercialization of TH-302 with Threshold receiving a tiered, double-digit royalty on sales. Under the royalty-bearing portion of the agreement, Threshold retains the option to co-promote TH-302 in the United States. Additionally, Threshold retains the option to co-commercialize TH-302 allowing the company to participate in up to 50% of the profits in the United States based on certain revenue tiers. Outside of the United States, Merck KGaA will be solely responsible for the commercialization of TH-302 with Threshold receiving a tiered, double-digit royalty on sales in these territories.
"The addition of TH-302 to our pipeline provides an important opportunity in several different tumor types to expand our oncology development program," said Susan Jane Herbert, Head of Global Business Development and Strategy, Merck Serono. "Given the fact that pancreatic cancer is a very difficult to treat indication, successful Phase II results could represent an important upside for our company."
"We are excited by the new resources that our partnership is going to bring to the development of TH-302 and the expertise in clinical development and commercialization that Merck will contribute to this program," said Barry Selick, President and CEO of Threshold. "This collaboration provides Threshold a strong and committed partner with a shared vision for TH-302."
Morrison & Foerster LLP acted as legal counsel for Threshold in this transaction.
TH-302 is a hypoxia-targeted drug that is thought to be activated under tumor hypoxic conditions, a hallmark for 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 550 patients in Phase I/II 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 ongoing clinical trials including, but not limited to, a controlled Phase 2 trial of TH-302 in combination with gemcitabine versus gemcitabine alone in patients with advanced pancreatic cancer and a Phase 3 study evaluating TH-302 in combination with doxorubicin versus doxorubicin alone in patients with soft tissue sarcoma.
TH-302 development in soft tissue sarcoma
A Phase 3 trial of TH-302 in patients with first-line advanced soft tissue sarcoma (STS) was initiated in September 2011, based on results from a Phase 1/2 trial investigating its use in combination with the chemotherapeutic doxorubicin. This randomized, multi-center Phase 3 trial will investigate the use of TH-302 plus doxorubicin compared with doxorubicin alone. The primary efficacy endpoint is overall survival. The study is conducted under a Special Protocol Assessment with the U.S. Food and Drug Administration. It is being run in partnership with the Sarcoma Alliance for Research through Collaboration (SARC) and aims to enroll 450 patients with metastatic or locally advanced unresectable STS.
TH-302 development in pancreatic cancer
Results from a randomized, controlled, multi-center Phase 2 trial of TH-302 in patients with first-line pancreatic cancer are expected to be announced in February 2012. This trial of 214 previously untreated patients with locally advanced unresectable or metastatic pancreatic adenocarcinoma started in June 2010, and completed enrollment in June 2011. Two different doses of TH-302 in combination with the chemotherapeutic gemcitabine were compared to gemcitabine alone, with progression free survival (PFS) as the primary endpoint.
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 American Cancer Society estimates that 10,980 people were diagnosed with a soft tissue sarcoma in the United States in 2011, and approximately 3,920 people died from the disease. In Europe, it is estimated that more than 32,000 people were diagnosed with soft tissue sarcoma in 2010.
Pancreatic cancer is a malignant neoplasm of the pancreas with current treatment options including surgery, radiotherapy and chemotherapy. Gemcitabine as a single agent or in combination with other treatments is the most commonly used chemotherapeutic agent in patients with advanced pancreatic cancer. It is estimated that approximately 279,000 cases of pancreatic cancer were diagnosed worldwide in 2008. Pancreatic cancer is the fourth most common cause of cancer death both in the United States and internationally. The American Cancer Society estimates that 44,030 people were diagnosed with pancreatic cancer in the United States in 2011, and approximately 37,660 people died from the disease.
