Inflectra Sales Lagging for Pfizer in Second Quarter

Pfizer announced some disappointing results for the second quarter in its quest to advance a foothold in the biosimilar market. The second-quarter results hinted at more difficulties to come for the Inflectra® brand, with the most recent launch of Merck’s Renflexis®.

Amid somewhat positive signs with group purchasing organizations, which supply hospitals and health systems, commercial health plans have lagged in covering the product. On the earnings call, John Young, Pfizer’s Group President for Pfizer Essential Health, said that in the second quarter, “our Inflectra share was 2.3% of the overall infliximab volume,” including both patients who had not used infliximab before and those who switched to Inflectra. The total US revenue for the quarter was only $23 million. In Europe, sales were $94 million—better but not yet gaining the penetration of other biosimilars in the EU.

The 15% discounting strategy may have limited uptake by US health plans and insurers to date, but Janssen’s actions to defend marketshare have no doubt been effective. Pfizer’s most recent price drop, coinciding roughly with the launch of Merck’s (and Samsung Bioepis’) infliximab biosimilar, will likely muddy this picture in the near term.

Overall, Pfizer’s revenue decreased by 2% (to $12.9 billion) compared with the second quarter of 2016. This is not terrible, considering that its European revenues from Enbrel® (etanercept) continue to be under siege from biosimilars, dropping 20% compared with Q2 2016.

Pfizer’s pipeline remains robust, however, with 8 biosimilars in the works, including 4 in phase 3 trials. Its epoetin alfa product Retacrit® had been rejected by the Food and Drug Administration (FDA) because of potential manufacturing concerns. The second-quarter financial report did not update its progress in discussions with FDA.
