The antirhinovirus agent chalcone Ro 090410 was tested in double-blind place-controlled volunteer trials for its protective efficacy against experimental rhinovirus infection. Fifty volunteers received either drug (26 volunteers) or placebo (24 volunteers) both before and after challenge with 2040 tissue culture infecting dose (TCID50) of human rhinovirus 2 (RV2). There was no evidence that medication significantly reduced the incidence of infection or illness, indeed there was some increase in the nasal secretion produced.
