Therapeutics (“Flamingo”) and Dynacure, announced today that the companies have signed a definitive merger agreement to combine their pipelines and expertise to create a leading oncology company. The combined company will advance Flamingo’s lead programs: danvatirsen in a Phase II trial PEMDA-HN in Head & Neck cancer (danvatirsen in combination with pembrolizumab) and other indications; and FTX-001 targeting MALAT-1 in cancer (IND ready). In addition, Flamingo’s current investors Kurma Partners (France) and PMV (Belgium) made a further investment in the company.

Danvatirsen is an antisense oligonucleotide (ASO) that selectively targets STAT3 and has shown clinical activity in two Phase II clinical studies. Danvatirsen binds to STAT3 mRNA, inhibiting translation of the transcript. The therapeutic effect of STAT3 suppression results in reduction of tumor cell growth as well as activation of anti-tumor immunity mediated by the tumor micro environment.

Currently, danvatirsen is planned to continue Phase 2 clinical development for head and neck squamous cell carcinoma to advance the program through key clinical milestones and data readouts. In addition, the combined company will also advance FTX-001, Flamingo’s most advanced long non-coding RNA (LncRNA) program which targets MALAT-1, through readiness for Phase 1 in solid tumors. LncRNAs are a large and untapped class of disease-causing targets within the “dark matter” of the human genome.

“The merger of Flamingo and Dynacure is a great strategic fit for both companies, leveraging a wealth of RNA therapeutic expertise and cancer drug development, and combining teams to create a stronger organization,” said Stephane van Rooijen, Chief Executive Officer of Flamingo.
“With our well-defined clinical strategy and operational plan, we are focused on creating value for all stakeholders, including patients, clinicians, and our investors. We plan to continue to execute upon our clinical strategy with the combined company and team in place.”

“We are delighted to join forces with the Dynacure team to execute an exciting transition plan for the long-term success and growth of Flamingo. The merger will focus our priorities on clinical execution, while adding additional resources,” added Michael Garrett, Chief Operating Officer of Flamingo.

Chris Mirabelli, Ph.D., Chairman of the combined company, added, “We have tremendous confidence in danvatirsen and our MALAT-1 targeted ASO (FTX-001), and look forward to delivering on our ambitious clinical plan with multiple readouts planned for 2024 and 2025.”

Brett P. Monia, Ph.D., Ionis’ Chief Executive Officer, added, “We are pleased that the combined company will advance Ionis-discovered cancer therapies where there is an unmet need, enabling Ionis to focus our resources on our pipeline priorities. The strength and dedication of the Flamingo leadership team, combined with their core expertise in oncology drug development, provide for a compelling foundation for future success for all stakeholders, including Ionis.”
