Clarus Therapeutics Inc. officially canceled plans to go public early this month, but its bid to develop the first oral testosterone-replacement product remains alive thanks to an efficient strategy. Clarus has kept its capital needs low by targeting a market, testosterone replacement, in which the requirements for securing U.S. approval are very clear. That gives it an edge over many other biotechs during a tough time — only six U.S. venture-backed biotechnology companies have gone public this year, according to VentureSource.
