6(S)-5-MTHF(Deplin)
Placebo/Deplin
Placebo/Placebo
Participants will receive 15 mg/day of Deplin, a medical food, for 8 weeks. The SPCD approach, is modified and conducted as follows: The phase II dataset of interest is limited to patients treated with placebo during phase I who completed phase I, who did not experience a clinical response according to the HDRS-17 during phase I and entered phase II. Drug is compared to placebo in phase II for this patient subset alone. The ITT/LOCF data comparing drug and placebo during phase I is combined with the data comparing drug and placebo according to the SPCD model for phase II (see steps 2 and 3 above), and analyzed using the statistical model as described in Fava et al, 2003
Participants will receive placebo for the first 4 weeks, and then 15 mg/day of Deplin (6(S)-5-MTHF) for the next 4 weeks. The SPCD approach, is modified and conducted as follows: The phase II dataset of interest is limited to patients treated with placebo during phase I who completed phase I, who did not experience a clinical response according to the HDRS-17 during phase I and entered phase II. Drug is compared to placebo in phase II for this patient subset alone. The ITT/LOCF data comparing drug and placebo during phase I is combined with the data comparing drug and placebo according to the SPCD model for phase II (see steps 2 and 3 above), and analyzed using the statistical model as described in Fava et al, 2003
Participants will receive placebo for both phases of the study. The SPCD approach, is modified and conducted as follows: The phase II dataset of interest is limited to patients treated with placebo during phase I who completed phase I, who did not experience a clinical response according to the HDRS-17 during phase I and entered phase II. Drug is compared to placebo in phase II for this patient subset alone. The ITT/LOCF data comparing drug and placebo during phase I is combined with the data comparing drug and placebo according to the SPCD model for phase II (see steps 2 and 3 above), and analyzed using the statistical model as described in Fava et al, 2003
