Trethera Corp., a biotechnology firm based in Brentwood, raised up to $8 million from investors, according to a securities filing posted March 11.

Trethera develops small molecules to fight certain types of blood cancer. In February 2018, it announced it had won federal approval to begin a clinical trial for a small molecule to treat myelodysplastic syndromes (MDS), a disease that can lead to bone marrow failure.

In October, it announced a collaboration with KYAN Therapeutics, a clinical-stage artificial intelligence drug development firm based in Singapore, to develop combination therapies for solid tumors.

Trethera Corp. was founded in 2015 by UCLA scientists Caius Radu, Johannes Czernin, David Nathanson, Owen Witte and Michael Jung, who developed the blockbuster drug Xtandi to treat prostate cancer, for which UCLA earned $1.14 billion.

The biotech firm raised $7.4 million from 40 investors during a previous funding round in February 2016, according to Crunchbase, a data tracking firm.stage
