Safety, Tolerability and Pharmacodynamic Effects of Sublingual Immunotherapy (Tablets) With Recombinant Bet v1

June 26, 2013 updated by: Stallergenes Greer

A Phase I Study to Investigate the Safety, Tolerability and Pharmacodynamic Effects of SLIT(Tablets) With Recombinant Bet v1 Given in Single Rising Doses and in Higher Multi Dose Regimens to Subjects Sensitised to Birch Pollen

To investigate the safety and tolerability of successive single rising doses of SLIT in subjects with allergic rhinitis and to investigate the safety and tolerability of multi high dose regimens of SLIT in subjects with allergic rhinitis.
