**Harvoni/Sovaldi IMS data weekended 1/2/15 is now available. Harvoni NRx is up to 2,526 from 2, 500, +1.0%, despite theNew Year's holiday, though up slightly less weekoverweek than we'd modeled. Viekira NRx/TRx totaled 50, though difficultto interpret in this early stage and given some data restrictions.**We assume multiple drivers in place, with warehousing + increased demand from Harvoni's better convenience offset bypotential insurance barriers; it's difficult to ascertain the net effects of these trends, though we now model Harvoni newpatient starts stabilizing as we enter 2015, its fourth month of launch, and look to coming weeks for evidence of resumptionof growth. **Sovaldi NRx was also up despite holiday and increased to 777 from 677, +14.8%, reflecting underlying demand from GT1patients for the new drug, in our view. Before the holiday season, Sovaldi NRx appeared to be settling at a runrate of 1,000scrips/week as the base demand from GT2/3s, which should be solid if things bounce back near to those levels. **Total prescriptions across GILD's HCV franchise were up weekoverweek, to 8,477 from 7,402, +14.5%. This includes thisweek's total NRx count of 3,303, plus refills from the 3,290 Harvoni scrips first filled four weeks ago, and the 1,111 Sovaldiscrips first filled eight weeks prior, for a total of 7,704 scrips with a slight refill ''excess'' implied by the difference in total TRXand expected total TRx. **Our tracker suggests Q4 U.S./WW sales of $3.02B/$3.77B, which given consensus numbers appearing to have comedown, should enable GILD to comfortably meet expectations depending in part on Harvoni inventory build and exU.S.uptake. **BOTTOM LINEGILD's total HCV franchise sales are entering the year at a favorable steadystate into the ABBV launch.
