**Harvoni/Sovaldi IMS data weekended 1/30/15 was released and show Harvoni volumes accelerating, with Sovaldi remaining in steady state. **Harvoni NRx are up to 3,781 from last week's 3,627, an increase of 4.2%. We believe this reflects increasing access and expect this to continue to rise over the next several weeks as additional insurance formularies come online following price negotiations. **Sovaldi Rx remain in steady state (NRx 771, TRx 1,941), continuing to suggest an equilibrium and that with our belief Sovaldi is now being used almost exclusively for GT2/ 3 patients, the product's runrate in the U.S. is approximately $3B. **Assuming modest (1.5%) weekoverweek increases in Harvoni new patient starts for the rest of the quarter then some modest weekly declines throughout the rest of the year due to competition and the initial bolus being worked through, our scripsbased projector suggests 2015 U.S. Harvoni sales of $8.6B. Adding the projected U.S. Sovaldi sales of $3.1B and exU. S. total HCV sales of $3.2B, fullyear HCV sales appear to be tracking at around $15Bwe believe at or above consensus, and illustrating how the increases in prescription volume can help offset the greaterthanexpected average discounts. **BOTTOM LINE: Acceleration of Harvoni prescriptions illustrates how volumes should help GILD offset the greaterthanexpected gross/net and enable fullyear HCV sales to meet/beat consensus and guidance, even if the greaterthanexpected discounting does suggests such volumes will need to be sustained longterm to enable continued robust sales. With large pharmas having similar modest (4-6%) EPS growth rates to GILD (AZN, GSK, JNJ) trading at a mean 16.5x, and minimal credit given to GILD's pipeline, we believe at a substantially discounted 9.8x multiple GILD looks relatively undervalued even with the longterm HCV uncertainties.
My comment - both TRx and NRx numbers for total HCV are new highs, even with better competition. Still amazed Olysio has held up so well (NRx as not really declined for weeks) with new all-orals around. Don't get it.
