11. Other Safety issues for discussion requested by the<br />

Member States<br />

11.1. Safety related variations of the marketing authorisation<br />

11.1.1. Azithromycin oral and intravenous formulations (NAP)<br />

<br />

PRAC consultation on a safety-related variations upon Finland’s request<br />

Regulatory details:<br />

Lead member: Terhi Lehtinen (FI)<br />

Administrative details:<br />

Procedure number: FI/H/XXXX/WS/23<br />

Procedure scope: PRAC consultation on a variation procedure evaluating the draft PASS protocol<br />

(A0661209) for a non-imposed non-interventional study in the Kaiser Permanente databases to<br />

examine the effects of azithromycin use on cardiovascular outcome<br />

MAH(s): Pfizer (Zithromax)<br />

Background<br />

Azithromycin is a macrolide antibiotic indicated for the treatment of infections caused by susceptible<br />

organisms (respiratory, skin and subcutaneous tissue, sexually transmitted disease (STD)).<br />

Azithromycin is also indicated in long term use in patients with advanced HIV infection for prophylaxis<br />

and treatment against Mycobacterium avium intracellular complex (MAC/DMAC).<br />

For background information, see PRAC Minutes January 2015. Following previous advice, the PRAC was<br />

further consulted on the evaluation of the MAH’s responses to a list of questions.<br />

Summary of advice and conclusion(s)<br />

Based on the review of the available information, the PRAC acknowledged the limitations in the<br />

proposed Veterans Affairs (VA) database study, and supported Finland’s view on potential confounding<br />

by indication and severity. The PRAC also supported that the population in the proposed study might<br />

not be representative of the population of interest. Therefore, the PRAC agreed with Finland’s<br />

conclusions that did not support the proposal to perform the VA database study, while PRAC agreed<br />

with pursuing studies using the Kaiser Permanente databases (North and South California; KPNC and<br />

KPSC).<br />
