Extension of a phase III trial (TEMSO) of oral teriflunomide in multiple sclerosis with relapses: safety outcomes with up to 4 years of follow-up

Background: Teriflunomide is a novel oral disease modifier in development for the treatment of relapsing forms of multiple sclerosis (RMS). Teriflunomide significantly reduced clinical and MRI disease activity and was well tolerated in the 2-year Phase III TEMSO study.
Objective: To report safety and tolerability of teriflunomide from the ongoing long-term extension of TEMSO (data cut-off: 23 February 2011).
Methods: Initially, 1088 RMS patients (18–55 years; Expanded Disability Status Scale scores <=5.5; >=1 relapse in the previous year or >=2 in the previous 2 years) were randomised (1:1:1) to placebo or teriflunomide, 7 mg or 14 mg/day for 108 weeks. 742 patients entered the long-term double-blind extension from 16 October 2006 to 29 April 2010; actively treated patients continued on their original dose, while those originally randomised to placebo were re-allocated to teriflunomide, 7 mg or 14 mg/day.
Results: Median duration of treatment in the extension was 2 years for both groups (min/max [days]: 5/1592 and 39/1527, for 7 mg and 14 mg, respectively). The incidence of treatment-emergent adverse events (TEAEs) reported in the extension was similar in both groups (7 mg: 83.6%; 14 mg: 84.6%). Most commonly reported TEAEs (MedDRA preferred term; 7 mg and 14 mg, respectively) were: nasopharyngitis (21.4% and 23.5%); headache (11.0% and 12.3%); ALT increase (12.0% and 11.8%); pain in extremity (7.6% and 10.6%); back pain (7.6% and 10.4%); diarrhoea (6.3% and 10.4%); urinary tract infection (7.3% and 9.5%); influenza (9.7% and 9.2%); paresthesia (6.3% and 8.4%); fatigue (11.2% and 7.8%). Serious TEAEs (7 mg: 15.4%; 14 mg: 11.5%) and TEAEs leading to permanent treatment discontinuation (7 mg: 9.1%; 14 mg: 6.2%) were higher in the 7 mg group. Two deaths (1 in each group) were reported in the extension. Medically confirmed malignancies as solid tumors only were reported with a low frequency: 2 cases in the 7 mg group (1 basal cell carcinoma, 1 colon cancer) and 2 cases in the 14 mg group (1 breast neoplasm, 1 small renal cell cancer). A low and similar incidence of serious infections and hepatic disorders was reported in both groups. Asymptomatic liver enzyme elevations, mostly ALT increases <3xULN, were the most commonly reported hepatic disorders.
Conclusion: Both doses of teriflunomide were well tolerated with up to 4 years of follow-up in the extension period with a favourable safety profile. Results were consistent with the core 2-year TEMSO study.
