FDA advisory panel backs expanded indication for Crestor (rosuvastatin) 1

The FDA Endocrinologic and Metabolic Drugs Advisory Committee voted 12-4 today in favor of an expanded indication for rosuvastatin (Crestor). According to an FDA analysis, the expanded indication means an additional 6.5 million people would be eligible to take the drug.

The AP’s Matthew Perrone wrote that the 4 negative votes came from panelists who “said they were uncomfortable recommending a drug with risks to patients who are healthy.”

Panel members said that the observed increase in diabetes was probably real, but that it was a class effect of statins and did not negate the beneficial effects of the drug. “I do think the diabetes problem is real, but I’m comforted by the fact that the drug works even in that patient group, so it’s very convincing,” said Michael Proschan, a statistician with the National Institutes of Health, in the AP report.

By contrast, the panel thought that the excess of gastrointestinal and neurological side effects observed in JUPITER were chance findings. “The biggest adverse effect is not being treated,” said the Gladstone Institute’s Thomas Bersot, in a heartwire story by Michael O’Riordan.

Panel member Sanjay Kaul, who voted with the majority, told CardioBrief that “the vote may not be an accurate reflection of the level of discussion,” since “the majority of the panelists expressed concerns about the potential of expanding the patient population eligible for statin therapy.” He said that the FDA often pays more attention to the details of the discussion than the actual votes, and that the real battle now will occur between AstraZeneca, who will look for the broadest possible indication, and FDA staff, who will pay close attention to the details of the discussion today.

Kaul noted that most events in JUPITER occurred in patients who had more than two risk factors, and that only a very modest benefit was observed in those with fewer risk factors. He also said that the diabetes risk observed in the trial was probably underestimated, since it relied only on investigator-reported diabetes, and would have been much higher if objective criteria had been used.

A Leerink Swann analyst wrote that “the FDA is unlikely to allow a total mortality claim.”

Earlier, in a series of twitter messages from the hearing, O’Riordan reported several interesting moments from the session:

  • At the FDA hearing: Ridker says screening and treatment based on JUPITER could prevent 250 000 events in the US over a five-year period.
  • FDA hearing: Panel member Sanjay Kaul asks about reliability of risk-benefit profile for rosuvastatin, given that JUPITER was halted early.
  • FDA hearing: “If you torture the data, it will confess,” says Rory Collins, of the ‘confusional state’ findings with rosuvastatin.

Specifically, the 14-12 vote was whether the benefits of rosuvastatin outweighed the risk in the following population:

  • Men greater than or equal to 50 years, women greater than or equal to 60 years;
  • Fasting LDL < 130 mg/dL; hsCRP greater than or equal to 2.0 mg/L; Triglycerides <500 mg/dL;
  • No prior history of cardiovascular or cerebrovascular events or coronary heart disease (CHD) risk equivalent as defined by NCEP ATP-III guidelines.

Favorable Vote from FDA Advisory Committee on Benefit/Risk of CRESTOR(R) (rosuvastatin calcium) in JUPITER Study

WILMINGTON, Del., Dec. 15 /PRNewswire-FirstCall/ — The U.S. Food and Drug Administration (FDA) Endocrinologic and Metabolic Drugs Advisory Committee (EMDAC) today voted 12 yes, 4 no, and 1 abstention that AstraZeneca has established sufficient benefit to offset the observed risks to support the use of CRESTOR® (rosuvastatin calcium) in individuals meeting the following criteria:

  --  Men greater than or equal to 50 years, women greater than or equal to
      60 years;
  --  Fasting LDL < 130 mg/dL; hsCRP greater than or equal to 2.0 mg/L;
      Triglycerides <500 mg/dL;
  --  No prior history of cardiovascular or cerebrovascular events or
      coronary heart disease (CHD) risk equivalent as defined by NCEP
      ATP-III guidelines.

The review, based on results of the JUPITER (Justification for the Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin) study, is part of the FDA’s evaluation of the supplemental New Drug Application (sNDA) filed by AstraZeneca in April 2009 to update the CRESTOR Prescribing Information with information about the impact of CRESTOR on reducing the risk of cardiovascular events.

“AstraZeneca welcomes the Advisory Committee’s positive vote,” said Howard Hutchinson, M.D., Chief Medical Officer, AstraZeneca. “Today’s discussions will help guide our ongoing dialogue with the FDA regarding our request for an indication that supports the use of CRESTOR for the prevention of cardiovascular disease in patients with an increased risk of experiencing cardiovascular events.”

The FDA Advisory Committee also discussed four non-voting items related to a range of other observations in JUPITER, including adverse events and whether the JUPITER trial identified an appropriate new target patient population.

The FDA frequently convenes advisory committee meetings to obtain independent expert guidance and opinions on clinical matters. While the FDA is not required to follow this guidance, the agency usually takes the advice into consideration when rendering its final decisions on pending applications and other public health matters.

ABOUT JUPITER:

Results from JUPITER (Justification for the Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin) were originally presented in November 2008 at the American Heart Association’s Annual Scientific Sessions, and published by the New England Journal of Medicine, evaluated the impact of rosuvastatin 20 mg on reducing CV events (combined risk of myocardial infarction, stroke, arterial revascularization, hospitalization for unstable angina, or death from CV causes).

JUPITER was a long-term, randomized, double-blind, placebo-controlled, large-scale study of 17,802 patients designed to determine if rosuvastatin 20 mg decreases the risk of myocardial infarction, stroke and other cardiovascular events in patients with LDL-C < 130 mg/dL but at increased cardiovascular risk as identified by age and elevated high-sensitivity C-reactive protein (hsCRP). The majority of patients had at least one other risk factor including hypertension, low HDL-C, family history of premature coronary heart disease (CHD) or smoking. hsCRP is a recognized marker of inflammation which is associated with an increased risk of atherosclerotic cardiovascular events.

JUPITER is a part of AstraZeneca’s extensive GALAXY clinical trials program, designed to address important unanswered questions in statin research. Currently, more than 65,000 patients have been recruited from 55 countries worldwide to participate in the GALAXY Program.

ABOUT CRESTOR (ROSUVASTATIN CALCIUM):

CRESTOR is indicated as an adjunct to diet to reduce elevated Total-C, LDL-C, ApoB, non-HDL-C, and TG levels and to increase HDL-C in patients with primary hyperlipidemia and mixed dyslipidemia. CRESTOR is also indicated as an adjunct to diet to slow the progression of atherosclerosis in adult patients as part of a treatment strategy to lower Total-C and LDL-C to target levels. CRESTOR is not approved to reduce cardiovascular morbidity and mortality.

IMPORTANT SAFETY INFORMATION:

CRESTOR is contraindicated in patients with a known hypersensitivity to any component of this product, in patients with active liver disease, which may include unexplained persistent elevations of hepatic transaminase levels, in women who are pregnant or may become pregnant, and in nursing mothers.

Cases of myopathy and rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with HMG-CoA reductase inhibitors, including CRESTOR. These risks can occur at any dose level, but are increased at the highest dose (40 mg).

CRESTOR should be prescribed with caution in patients with predisposing factors for myopathy (eg, age greater than or equal to 65 years, inadequately treated hypothyroidism, renal impairment). The risk of myopathy during treatment with CRESTOR may be increased with concurrent administration of some other lipid-lowering therapies (fibrates or niacin), gemfibrozil, cyclosporine, or lopinavir/ritonavir.

Therapy with CRESTOR should be discontinued if markedly elevated CK levels occur or myopathy is diagnosed or suspected. All patients should be advised to promptly report unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever. It is recommended that liver enzyme tests be performed before and at 12 weeks following both the initiation of therapy and any elevation of dose, and periodically (e.g., semiannually) thereafter. Should an increase in ALT or AST of >3 times ULN persist, reduction of dose or withdrawal of CRESTOR is recommended. CRESTOR should be used with caution in patients who consume substantial quantities of alcohol.

CRESTOR 40 mg should be used only for those patients not achieving their LDL-C goal with 20 mg. Patients initiating CRESTOR therapy or switching from another statin should begin treatment with CRESTOR at the appropriate starting dose.

In the controlled clinical trials database, the most common adverse reactions were headache (3.7%), myalgia (3.1%), abdominal pain (2.6%), asthenia (2.5%), and nausea (2.2%).
