The Phase I trial for AC430 is a two part, placebo-controlled, single ascending, and multiple ascending dose trial in healthy volunteers.
In the trial, AC430 will be administered orally once-daily and doses escalated until a maximum tolerated or maximum feasible dose is established.
In addition to evaluating the safety, tolerability, and pharmacokinetics of AC430, the study will also assess cytokine signal transduction.
The Phase I trial for AC480 is a multi-center, dose escalation study with AC480 administered by intravenous infusion on days one and two of a 21 day cycle, either alone or in combination with docetaxel.
Ambit president and CEO Alan Lewis said that the initiations of these studies are important milestones.
"AC430 has demonstrated convincing efficacy in pre-clinical models of autoimmune and inflammatory diseases, and AC480 IV was developed to assess whether pulsatile doses of a pan-HER inhibitor administered in combination with a taxane such as docetaxal would produce synergistic anti-tumor activity," Lewis said.
