A national group of independent pharmacists Wednesday called on the Federal Trade Commission to conduct an extensive investigation of alleged anticompetitive conduct by CVS Caremark Corp. (CVS) and to consider reopening the 2007 merger that formed the hybrid drug retailer and pharmacy benefits manager.

Representatives of the National Community Pharmacists Association, with pharmacy customers in tow, met with FTC Chairman Jon Leibowitz to raise antitrust and consumer-protection concerns about CVS Caremark, including the group's assertion the company is improperly steering its prescription benefits patients to CVS drug stores.

The pharmacists, in Washington for an annual meeting, also met with lawmakers to express their concerns about CVS Caremark and the pharmacy benefits management, or PBM, industry, and asked members of Congress to request that the FTC review the CVS Caremark merger. The group, which had opposed the merger, has been pressing the FTC in recent months to investigate the company and its conduct.

"We are cautiously optimistic about the results of our meeting," with Leibowitz, said NCPA President Holly Whitcomb Henry in a conference call with reporters.

"Based on today's meeting, we're hopeful and encouraged, but we'll see what happens," said the group's general counsel, Joanne Thelmo.

CVS Caremark's conduct harms community pharmacies, and "more importantly their anticompetitive behavior is harming our patients and our customers and that's what we're really concerned about," said Henry, who operates three pharmacies with her husband in the Seattle area. The company's actions increase costs, limits patient choice and access, and reduce quality and convenience for patients, she said.

The group presented in writing numerous examples of conduct it considers problematic, and five pharmacists and a North Carolina couple spoke with the FTC about specific situations, according to Henry.

In a letter to Leibowitz written in advance of the meeting, the NCPA said CVS Caremark dominates the pharmaceutical services industry and its retail business is using its pharmacy benefits management operation to "eliminate consumer choice and drive consumers from rival pharmacies."

One of the group's key concerns -- though not its only one -- revolves around CVS Caremark's "maintenance choice" program, which allows the company's pharmacy benefits management members to buy medications for chronic conditions at CVS stores for the same price they would pay at the company's mail-order pharmacy.

CVS Caremark considers the program an added convenience for patients whose employers' drug-benefit plans require them to use mail-order supplies for maintenance medications. The community pharmacists and other critics, however, say the program unfairly steers patients from other drug stores, and the NCPA alleges the company improperly uses private patient information to do so.

"We disagree with NCPA's mischaracterization of our business practices," said CVS Caremark spokeswoman Carolyn Castel. "The merger of CVS and Caremark is, in fact, making pharmacy health care more accessible, more effective and more affordable. Our integrated pharmacy and PBM operations provide greater choice and more convenience for patients, improve health outcomes, and lower overall health care costs for plan sponsors and participants."

The NCPA, in its letter, asked the FTC to investigate CVS Caremark "to attack both anticompetitive and deceptive conduct," and to "consider whether CVS' consummated acquisition of Caremark has reduced competition in the pharmacy and PBM markets, and seek appropriate relief, including imposition of enforceable firewalls and non-discrimination obligations, or divestiture, if necessary." The group is working with lawyer David Balto, a former policy director of the FTC's competition bureau.

The group also asked that the FTC require Caremark, the PBM part of the company, to treat all pharmacies in a nondiscriminatory fashion, bar CVS from creating programs that "disadvantage rivals by imposing higher costs on them," and prevent Caremark from sharing sensitive patient information with CVS.

The FTC had no comment.

CVS Caremark is coming under criticism from consumers and others. Last week, a group of state legislators - the National Legislative Association on Prescription Drug Prices - asked the FTC to investigate the company as well, saying the merger "created a heightened opportunity for anticompetitive and exclusionary conduct that harms consumers by increasing the price of drugs and limiting patients' access to pharmaceutical care."

The calls for closer scrutiny of CVS Caremark come as another major PBM, Express Scripts Inc. (ESRX), seeks to acquire the pharmacy benefits management business of health insurer WellPoint Inc. (WLP). The NCPA opposes that merger and has asked the FTC to investigate it, asserting it would harm consumers by further concentrating the PBM industry.

JPMorgan analyst Lisa Gill, in a note, said she wouldn't be surprised if the FTC looked into the CVS Caremark merger, given the Obama administration's view on vertical transactions. She said she remained confident, however, that the company provides choice to its PBM members and isn't abusing its power in the marketplace. Employers, not the PBM, make the decisions on prescription-benefit plan designs, noted Gill. She added that the patients are receiving better prices at CVS stores than at the independent pharmacies.
