The collaboration, launched in 2019, has successfully combined MD Anderson’s innovative clinical research infrastructure and the patient-driven drug development capabilities of the Therapeutics Discovery division with Boehringer Ingelheim’s pipeline of innovative cancer medicines and expertise in advancing breakthrough therapies. Under the new agreement, joint research will continue for five additional years.

"Our collaboration with MD Anderson strengthens our determination to find solutions for the most difficult-to-treat cancers, and this latest commitment marks an important step forward, especially in our holistic KRAS program," said Norbert Kraut, Ph.D., Head of Global Cancer Research at Boehringer Ingelheim. "We are delighted to extend our collaboration with MD Anderson. With our shared dedication to patients and like-minded approach to innovation, we have the potential to bring the medicines to lung and gastrointestinal cancer patients that they so much need."

The flexible nature of the VRDC agreement allows the teams to expand their lung cancer indication programs targeting KRAS and TRAILR2, including Boehringer Ingelheim’s first-in-class SOS1::pan-KRAS inhibitor (BI 1701963), inhibitors of KRAS G12C (BI 1823911) and MEK (BI 3011441), as well as a novel undisclosed bi-specific TRAILR2 agonist.

The collaboration already has resulted in a number of joint publications1, conference presentations (including at the 2021 AACR (Free AACR Whitepaper) Annual Meeting2) and clinical trial activities. Boehringer Ingelheim is pursuing a comprehensive mutant KRAS-directed effort with multiple programs expected to enter the VRDC with MD Anderson.

"We are proud to expand our work with Boehringer Ingelheim in a very exciting drug-development space – advancing novel targeted therapies against KRAS and TRAILR2," said Timothy Heffernan, Ph.D., Head of Oncology Research in Therapeutics Discovery at MD Anderson. "Our collaboration is built upon a strong working relationship and complementary expertise, highlighting how an academic center and a pharmaceutical company can strategically work together to advance innovative therapies for patients with cancer."
MD Anderson’s Therapeutics Discovery division is anchored by an experienced team of drug development experts working to advance the next generation of cancer therapies. The Translational Research to Advance Therapeutics and Innovation in Oncology (TRACTION) platform, led by Heffernan, performs cutting-edge translational research to rapidly advance new therapies to the patients most likely to benefit.

KRAS is the most frequently mutated cancer-causing oncogene. One in seven of all human metastatic cancers expresses KRAS mutations, with mutation rates of more than 30 percent in lung adenocarcinomas, more than 40 percent in colorectal cancers and more than 90 percent in pancreatic cancers. No approved treatments for KRAS-driven cancers exist currently, further underscoring the need for continued investment in research and development. Tumor cell-selective activation of TRAILR2 can trigger cancer cell death in indications of high medical need, including lung and gastrointestinal malignancies.

On April 14, 2021 Aura Biosciences, a clinical-stage oncology company developing a novel class of virus-like drug conjugate (VDC) therapies for multiple oncology indications, reported the online publication of data in the peer-reviewed medical journal Cancer Immunology Research, a journal of the American Association for Cancer Research (AACR) (Free AACR Whitepaper), that supports the broad application of the Company’s proprietary VDC technology platform for treating cancer (Press release, Aura Biosciences, APR 14, 2021, View Source [SID1234578022]). The manuscript, titled, "Virus-like Particle-drug Conjugates Induce Protective, Long-lasting Adaptive Anti-Tumor Immunity in the Absence of Specifically Targeted Tumor Antigens," describes promising long term anti-tumor activity of AU-011, the Company’s lead VDC candidate, as a monotherapy and in combination with checkpoint inhibitor antibodies in preclinical studies conducted in collaboration with the Center for Cancer Research at the National Cancer Institute of the National Institutes of Health.

"Collectively, these promising results confirm treatment of AU-011 resulted in targeted tumor cytotoxicity with hallmarks of immunogenic cell death that may promote a durable anti-tumor immune response," said Cadmus C. Rich, MD, MBA, Chief Medical Officer and Head of R&D for Aura. "Additionally, the additive activity of AU-011 in combination with checkpoint inhibitors has shown a high level of durable complete responses and prevention of tumor recurrence, warranting continued research into its potential clinical utility to effectively treat multiple types of tumors like non-muscle invasive bladder cancer as a primary treatment and further prevent metastatic disease."

Key findings from the manuscript include:

In vitro and in vivo studies in immunocompetent murine tumor models demonstrated a dose-dependent cytotoxic response of AU-011 with an upregulation of the markers of immunogenic cell death like caspase-1 and calreticulin surface expression demonstrating that AU-011 mediated cell death was able to generate potent immune stimulatory conditions within the tumor microenvironment.

A single in vivo dose administration of AU-011 caused rapid cell death leading to long term complete responses in 50% of all animals. Combination with immune checkpoint inhibitor antibodies improved therapeutic efficacy resulting in 70-100% complete response rate that was durable 100 days post-treatment with 50-80% of those animals displaying protection from secondary tumor re-challenge.

Depletion studies of CD4+ or CD8+ T-cells at the time of AU-011 treatment or tumor re-challenge confirmed the involvement of both cell populations in the mechanism of action of AU-011 and the promotion of long-lasting anti-tumor protection.

"These promising findings further reinforce the therapeutic advantages of VDCs in treating cancer compared to other available treatments, which include the broad tumor selectivity and multivalent binding of the virus-like particles compared to antibodies, the ability to deliver hundreds of cytotoxic molecules and the generation of long-lasting anti-tumor immunity," said Elisabet de los Pinos, Ph.D., Chief Executive Officer of Aura. "While our initial clinical focus has been in ocular oncology, our VDC approach has wide application as a single agent and as a combination therapy in a variety of solid tumors, including non-muscle invasive bladder cancer, which is expected to enter the clinic in 2022 We remain focused on advancing our novel VDC approach to transform the treatment of tumors and improve outcomes for patients with cancer."

About AU-011 (belzupacap sarotalocan)

AU-011 is a first-in-class virus-like drug conjugate (VDC) therapy in development for the first line treatment of choroidal melanoma. The virus-like component of the VDC selectively binds unique heparan sulphate proteoglycans (HSPGs) that are modified and overexpressed on the tumor cell surface of choroidal melanoma (and other tumor types) and delivers a potent cytotoxic drug that is activated with infrared light. Upon activation with an ophthalmic laser, the cytotoxic drug rapidly and specifically disrupts the cell membrane of malignant melanoma cells with a pro-immunogenic cell death that can activate the immune system generating long term anti-tumor immunity. The unique specificity of tumor binding by the VDC enables the preservation of key eye structures, which may allow for the potential of preserving patients’ vision and reducing other long-term complications of radiation treatment. The possibility of early treatment intervention and the activation of the immune system could lead to a reduction in the metastases rate for patients with this life-threatening disease. AU-011 can be delivered using equipment commonly found in an ophthalmologist’s office and does not require a surgical procedure, pointing to a potentially less invasive, more convenient therapy for patients and physicians. AU-011 for the treatment of choroidal melanoma has been granted Orphan Drug and Fast Track designations by the U.S. Food and Drug Administration and is currently in Phase 2 clinical development.

Ependymoma is a rare type of tumor that can form in the brain or spinal cord. Ependymoma begins in the ependymal cells in the brain and spinal cord that line the passageways where the fluid (cerebrospinal fluid) that nourishes your brain flows. Ependymoma can occur at any age, but most often occurs in young children.

"The FDA’s recognition of the high prevalence and unmet needs in the treatment landscape for ependymoma, especially in pediatric patients is a significant milestone as we continue to advance and expand the WP1066 development program. We currently have Orphan Drug Designation for WP1066 for the treatment of brain tumors, as well as RPD designation for three other pediatric indications, and believe that ependymoma represents another important rare indication. We continue to be encouraged by the data WP1066 has demonstrated to date and believe it has the potential to be an effective therapy for pediatric patients with ependymoma," commented Walter Klemp, Chairman and CEO of Moleculin.

The Rare Pediatric Disease Priority Review Voucher program, which was created as part of the Food and Drug Administration Safety and Innovation Act (FDASIA) of 2012, is intended to incentivize the development of new therapies for rare pediatric diseases. Under the FDA’s rare pediatric disease designation program, the FDA may grant a priority review voucher to a sponsor who receives a product approval for a "rare pediatric disease," which is defined as a serious or life-threatening disease in which the serious or life-threatening manifestations primarily affect individuals aged from birth to 18 years and affects fewer than 200,000 people in the U.S. Subject to FDA approval of WP1066 for the treatment of ependymoma, Moleculin would be eligible to receive a voucher that may be redeemed to receive priority review for a subsequent marketing application for a different product candidate or which could be sold or transferred.

About WP1066

WP1066 is an immune/transcription modulator capable of directly inhibiting certain key oncogenic transcription factors, including the activated form of a protein known as STAT3. The activated form of STAT3 referred to as p-STAT3, is considered a master regulator of tumor activity. In addition to inhibiting p-STAT3 and several other signaling proteins linked to tumor development, WP1066 has also been shown in animal models to stimulate a natural immune response and immune memory to fight tumor progression.
