A Randomized, Double-blind, Placebo Controlled Trial to Evaluate the Safety, Tolerability and Antiviral Activity of 12 Weeks' Treatment With a New Antiviral HCMV Drug

• Evidence of post transplantation engraftment
• Able to swallow tablets.

Exclusion Criteria:

• Previous anti-HCMV therapy after this allogeneic HBPC transplantation
• Mismatched or cord blood transplant recipients
• Current or history of end-organ HCMV disease
• Graft versus host disease (GVHD)
• Impaired liver function
• Reduced renal function
