Flamingo Therapeutics

Flamingo Therapeutics is a biotechnology company specializing in RNA-targeted therapies for oncology. Founded in 2019, the company focuses on developing treatments for difficult-to-treat cancers using state-of-the-art chemistries and a clinical-stage pipeline targeting undruggable transcription factors and splice variants. Flamingo's lead program is danvatirsen, an antisense oligonucleotide (ASO) that selectively targets STAT3 and has shown clinical activity in two Phase II studies. Danvatirsen binds to STAT3 mRNA, inhibiting translation of the transcript, resulting in reduced tumor cell growth and activation of anti-tumor immunity. Flamingo initiated the PEMDA-HN Phase II trial evaluating danvatirsen in combination with pembrolizumab for patients with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). The company is also advancing FTX-001, its most advanced long non-coding RNA (LncRNA) program targeting MALAT-1, through readiness for Phase 1 trials in solid tumors. Flamingo's proprietary discovery engine, FLAME (Flamingo LncRNA Antisense Mining Engine), addresses lncRNAs, a large and untapped class of disease-causing targets within the "dark matter" of the human genome. In March 2023, Flamingo merged with Dynacure to create a leading RNA therapeutics company focused on clinical oncology, combining their pipelines and expertise.

Key customers and partnerships

Flamingo Therapeutics has established strategic alliances and partnerships to advance its RNA-targeted therapies. The company has an expanded alliance with Ionis Pharmaceuticals, a world leader in RNA-targeted antisense oligonucleotide (ASO) therapeutics. This partnership, announced in September 2021, combines three clinical-stage programs from Ionis with Flamingo's novel lncRNA discovery engine and preclinical lncRNA program. The alliance leverages Flamingo's expertise in oncology and long non-coding RNAs with Ionis' proficiency in RNA-targeted drug discovery and development. Additionally, Flamingo collaborates with academic partners at VIB, KU Leuven, Ghent University, and the University of Michigan, whose pioneering work in non-coding RNA genes in cancer contributed to the company's foundation. In June 2023, Flamingo received a EUR 1.7 million research grant from Flanders Innovation & Entrepreneurship (VLAIO) to advance its RNA-targeting oncology portfolio, further validating its approach in creating a pipeline of programs targeting undruggable transcription factors and non-coding RNA.
