Moffitt Cancer Center Grants Aptose Exclusive Global Rights to Highly Potent Multi-Targeting Epigenetic Inhibitors
Exclusive Agreement with Laxai Avanti Life Sciences to Design Next Generation Epigenetic Therapeutics
REDWOOD CITY, Calif., TORONTO, TAMPA, Fla. and HYDERABAD, India, Nov. 10, 2015 (GLOBE NEWSWIRE) -- Aptose Biosciences Inc. (Nasdaq:APTO) (TSX:APS), a clinical-stage company developing new therapeutics and molecular diagnostics that target the underlying mechanisms of cancer, today announced two collaborations that will provide exclusive access to new epigenetic therapeutics for the Company’s oncology pipeline. These partnerships have been strategically formed to leverage Aptose’s scientific and clinical expertise in cancer and hematologic diseases to develop mechanistically differentiated and high-value epigenetic drug candidates.
Strategic Collaboration with Moffitt Cancer Center
Aptose has entered into a definitive agreement with Moffitt Cancer Center for exclusive global rights to potent, multi-targeting, single-agent inhibitors for the treatment of hematologic and solid tumor cancers. These small molecule agents are highly differentiated inhibitors of the Bromodomain and Extra-Terminal motif (BET) protein family members, which simultaneously target specific kinase enzymes. The molecules developed by Moffitt exhibit single-digit nanomolar potency against the BET family members and specific oncogenic kinases which, when inhibited, are synergistic with BET inhibition. Under the agreement, Aptose will gain access to the drug candidates developed by Moffitt and the underlying intellectual property covering the chemical modifications enabling potent bromodomain (BRD) inhibition on the chemical backbone of a kinase inhibitor. Aptose expects lead clinical candidates to emerge from the collaboration by late 2016.
Transcriptional dysregulation in cancer cells may occur through various means, including chromatin remodeling, histone modification and super-enhancer formation. The bromodomain proteins play a critical role in this dysregulation, and hence targeting specific bromodomains represents a validated treatment approach for various cancers. Aptose is committed to developing a pipeline of molecules that inhibit key epigenetic targets with the potential to intervene in oncogenesis and induce remission.
“We’ve built an oncology drug development organization with valuable ties to leading clinical centers and thought leaders,” said William G. Rice, Ph.D., Chairman, President and CEO, “and we are exceptionally pleased to partner with Moffitt on advancing new epigenetic inhibitors, specifically bromodomain inhibitors that simultaneously inhibit specific kinases in key regulatory pathways.”
“Aptose views a multi-targeting approach, which incorporates bromodomain inhibition, as an exciting means to enhance efficacy and diminish therapeutic resistance relative to the current landscape in cancer treatment. This is even more beneficial when inhibition of the pathways is highly synergistic. The researchers at Moffitt have made unprecedented progress in this field,” continued Dr. Rice.
“We view the advancement of epigenetic multi-inhibitors as a highly promising strategy in the treatment of cancer,” said the principal investigators Ernst Schonbrunn, Ph.D. and Nicholas Lawrence, Ph.D., members of the Drug Discovery Program at Moffitt, “and targeting broad-acting epigenetic regulators of transcription like bromodomain proteins is needed to suppress the induction of gene expression that results when cancer cells respond to kinase inhibitors.”
“We are excited to work with an organization as scientifically driven to develop novel therapeutics as Aptose,” said Haskell Adler, Ph.D., MBA, Senior Licensing Manager at Moffitt.
Exclusive Agreement with Laxai Avanti Life Sciences
Aptose today also announced an exclusive drug discovery partnership with Laxai Avanti Life Sciences (LALS) for their expertise in next generation epigenetic-based therapies. Under the agreement, LALS will be responsible for developing multiple clinical candidates, including optimizing candidates derived from Aptose’s relationship with the Moffitt Cancer Center. Aptose will own global rights to all newly discovered candidates characterized and optimized under the collaboration, including all generated intellectual property.
“We have identified LALS as an organization with high-caliber medicinal chemistry and with robust, and highly efficient drug discovery capabilities that complement our capabilities at Aptose,” said Dr. Rice. “These collaborations are designed to build upon insights into the epigenetic field that were informed by the mechanism of APTO-253. As we continue to advance APTO-253 into late-stage clinical development, we are committed to creating and acquiring additional differentiated agents and building a staged oncology pipeline behind APTO-253.”
About APTO-253
Epigenetic suppression of the KLF4 gene has been reported in the scientific literature as a key transforming event in AML and high-risk myelodysplastic syndromes. APTO-253, Aptose’s lead drug candidate, is a first-in-class inducer of the Krüppel-like factor 4 (KLF4) tumor suppressor gene, and the only clinical-stage compound targeted for patients with suppressed KLF4 levels. APTO-253 has demonstrated a favorable safety profile with no evidence of bone marrow suppression. Preclinical studies have shown potent single-agent activity and an opportunity for combination therapy with a variety of anti-cancer therapeutics. The drug candidate is in a Phase 1b clinical study in patients with relapsed or refractory hematologic malignancies.
