The following article may help u out for determination of sample size assuming different variances of test and reference formulation which is recommanded by FDA.

"Hansheng Wang and Shein-Chung Chow, A practical approach for comparing means of two groups without equal variance assumption, Statistics in Medicine 2002; 21:3137–3151" :-P
