There is another (possible) weakness with Aberelix. Safety, immuno-toxicity.

<<We observed some adverse reactions in patients during our abarelix depot studies, including allergic reactions and temporary and reversible elevation of some liver enzymes.>>

A is chimeric, and long exposure may trigger anti-antibody. AMGN/PRCS did run third (toxicology) PIII trials, 12 months, but never disclose data.

Few days ago I sold my small PRCS position because: 1) do not expect timely FDA respond on fast track NDA file, 2) concern about safety, 3)competition from ATIS formulation, and 4)negative from TAP (price pressure).

This was preventive action, and may be premature.
