881 F. Supp. 2d 1333
N.D. Ala.2012Background
- MDL product liability action concerning Chantix (varenicline) for smoking cessation.
- FDA approved Chantix in May 2006; plaintiffs allege neuropsychiatric harms including depression and suicidality.
- Label warnings evolved, culminating in a July 2009 black box warning and a concurrent Medication Guide.
- Plaintiffs argue the 2009 warning is insufficient and seeks to toll or trigger statute-of-limitations issues; defendant argues the 2009 warning is adequate as a matter of law.
- Court applies learned intermediary doctrine, attributing warnings to physicians; focus is on adequacy of the 2009 label and its impact on liability.
- Court distinguishes post-2009 claims and allows case-specific challenges to limitations timing rather than a blanket ruling.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Adequacy of the 2009 boxed warning | Glenmullen supports inadequacy of 2009 warning | Label adequately warns of neuropsychiatric risks | 2009 warning deemed adequate as a matter of law |
| Statute of limitations timing | Running of limitations cannot be blanketly tied to 2009 warning | Limitations should start after July 1, 2009 | Case-by-case analysis; allow motions in individual cases; not a blanket ruling |
| Role of learned intermediary doctrine | Physician warning to patient remains inadequate irrespective of doctor judgment | Warning to physicians suffices; doctors decide prescribing | Court sustains sufficiency of physician-directed warning under learned intermediary doctrine |
