Material Changes and Developments
- Regulatory Approval: The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a positive opinion recommending marketing authorization for Tivicay (dolutegravir).
- Indication: The approval covers the treatment of HIV-infected adults and adolescents above 12 years of age in combination with other antiretroviral medicinal products.
- Timeline: The European Commission's final marketing authorization decision is expected early in 2014.
- Clinical Basis: The opinion is based on safety and efficacy data from four pivotal Phase III studies involving more than 2,500 patients, including treatment-naive and treatment-experienced individuals.
Outlook, Risks, and Management Commentary
Management Commentary: Dr. John Pottage, Chief Medical Officer of ViiV Healthcare, stated that the positive opinion brings the company closer to offering a new treatment option to patients across Europe. He emphasized the company's commitment to research and acknowledged the contribution of thousands of patients in clinical development.
Pipeline and Strategy: Regulatory applications for a single-tablet regimen (STR) combining Tivicay with Kivexa/Epzicom were submitted to authorities in Europe, Canada, and the U.S. in October 2013. Applications are also being evaluated in other countries worldwide.
Risks and Safety Information:
- Contraindications: Co-administration with dofetilide is contraindicated due to the risk of serious or life-threatening events.
- Hypersensitivity: Reactions including rash, fever, and organ dysfunction (including liver injury) have been reported in 1% or fewer subjects. Immediate discontinuation is required if symptoms develop.
- Hepatitis: Patients with underlying Hepatitis B or C may be at increased risk for transaminase elevations.
- Drug Interactions: Strong inducers of UGT1A1 and/or CYP3A4 may reduce dolutegravir plasma concentrations. Specific timing is required when taking cation-containing antacids or supplements.
- Forward-Looking Statements: GSK cautions that actual results may differ materially from projections due to risks and uncertainties described in their 2012 Form 20-F.
