Background on BAF312 (Siponimod)

BAF312 is a potent and selective agonist of S1P with EC50 value of 0.39nM for S1P1 receptors and 0.98nM for S1P5 receptors, respectively [1].

BAF312 has shown >1000-fold selectivity for S1P1 versus S1P2, S1P3 and S1P4 receptors [1]. In vitro metabolism studies with liver microsomes have shown that the metabolic clearance of BAF312 is high in rat, low to moderate in monkey and human being, and low in dog and mouse. Moreover, BAF312 has been revealed to dose-dependently reduce peripheral lymphocyte counts in Lewis rats [2].

Pharmacokinetics, safety, and tolerability of siponimod (BAF312) in subjects with different levels of hepatic impairment: a single-dose, open-label, parallel-group study.[Pubmed:27443658]

Int J Clin Pharmacol Ther. 2017 Jan;55(1):41-53.

OBJECTIVE: To assess the pharmacokinetics (PK), safety, and tolerability of siponimod and major metabolites in subjects with mild, moderate, and severe hepatic impairment (HI) compared with demographically-matched healthy subjects (HS). METHODS: This open-label, parallel-group study enrolled 40 subjects (each HI group, n = 8; HS group, n = 16). A staged design was employed starting with the enrollment of subjects with mild HI, followed by those with moderate and severe HI. All subjects received single oral doses of 0.25 mg siponimod on day 1; PK and safety data were collected during the 21-day follow-up. RESULTS: All subjects had similar baseline characteristics and completed the study. No significant differences were observed in the plasma exposure of siponimod in mild, moderate, and severe HI groups vs. HS: Cmax changed by 16%, -13%, and -16%; AUC by 5%, -13%, and 15%, respectively. The unbound siponimod PK parameters vs. HS were similar in the mild HI, and increased in the moderate (Cmax, 15%; AUC, 17%) and severe HI groups (Cmax, 11%; AUC, 50%). Exposure of M3 and M5 also showed 2- to 5-fold increase, particularly in the moderate and severe HI groups vs HS. There were no clinically-relevant safety findings. CONCLUSIONS: Single oral doses of 0.25 mg siponimod were well tolerated, and HI did not significantly alter exposure to siponimod. Increase in the M3 and M5 metabolites requires further evaluation. These results do not warrant any dose adjustments of siponimod in subjects with HI..

Siponimod (BAF312) prevents synaptic neurodegeneration in experimental multiple sclerosis.[Pubmed:27566665]

J Neuroinflammation. 2016 Aug 26;13(1):207.

BACKGROUND: Data from multiple sclerosis (MS) and the MS rodent model, experimental autoimmune encephalomyelitis (EAE), highlighted an inflammation-dependent synaptopathy at the basis of the neurodegenerative damage causing irreversible disability in these disorders. This synaptopathy is characterized by an imbalance between glutamatergic and GABAergic transmission and has been proposed to be a potential therapeutic target. Siponimod (BAF312), a selective sphingosine 1-phosphate1,5 receptor modulator, is currently under investigation in a clinical trial in secondary progressive MS patients. We investigated whether siponimod, in addition to its peripheral immune modulation, may exert direct neuroprotective effects in the central nervous system (CNS) of mice with chronic progressive EAE. METHODS: Minipumps allowing continuous intracerebroventricular (icv) infusion of siponimod for 4 weeks were implanted into C57BL/6 mice subjected to MOG35-55-induced EAE. Electrophysiology, immunohistochemistry, western blot, qPCR experiments, and peripheral lymphocyte counts were performed. In addition, the effect of siponimod on activated microglia was assessed in vitro to confirm the direct effect of the drug on CNS-resident immune cells. RESULTS: Siponimod administration (0.45 mug/day) induced a significant beneficial effect on EAE clinical scores with minimal effect on peripheral lymphocyte counts. Siponimod rescued defective GABAergic transmission in the striatum of EAE, without correcting the EAE-induced alterations of glutamatergic transmission. We observed a significant attenuation of astrogliosis and microgliosis together with reduced lymphocyte infiltration in the striatum of EAE mice treated with siponimod. Interestingly, siponimod reduced the release of IL-6 and RANTES from activated microglial cells in vitro, which might explain the reduced lymphocyte infiltration. Furthermore, the loss of parvalbumin-positive (PV+) GABAergic interneurons typical of EAE brains was rescued by siponimod treatment, providing a plausible explanation of the selective effects of this drug on inhibitory synaptic transmission. CONCLUSIONS: Altogether, our results show that siponimod has neuroprotective effects in the CNS of EAE mice, which are likely independent of its peripheral immune effect, suggesting that this drug could be effective in limiting neurodegenerative pathological processes in MS.

Pharmacokinetics, safety, and tolerability of siponimod (BAF312) in subjects with severe renal impairment: A single-dose, open-label, parallel-group study.[Pubmed:27841151]

Int J Clin Pharmacol Ther. 2017 Jan;55(1):54-65.

OBJECTIVE: To investigate the pharmacokinetics (PK), safety, and tolerability of siponimod and selected inactive metabolites (M3 and M5) in subjects with varying degrees of renal impairment (RI) compared to demographically matched healthy subjects (HS). METHODS: The study enrolled subjects with severe RI (n = 8) and matched HS (n = 8). Subjects with moderate and mild RI were to be enrolled only if interim analysis showed >/= 50% increase in maximum plasma concentration (Cmax) or area under the curve (AUC) of total and/or unbound siponimod in severe RI subjects vs. HS. All subjects received a single oral dose of siponimod 0.25 mg on day 1; PK and safety were evaluated during the follow-up (~ 13 days). RESULTS: PK of siponimod was marginally affected in severe RI subjects vs. HS: Cmax decreased by 8%, and AUClast and AUCinf increased by 23% and 24%, respectively; half-life (37 vs. 26 hours) and systemic clearance (2.9 vs. 3.4 L/h) were comparable. Siponimod plasma unbound (u) fraction at 4 hours post-dose was similar between the two groups (range: 0.0172 - 0.0550%). Cmax(u) was comparable while AUClast(u) and AUCinf(u) were increased by 33% compared to HS. M3 exposure was similar (Cmax decreased by 9%; AUClast and AUCinf increased by 11%) and M5 exposure was slightly lower (Cmax decreased by 26%; AUClast decreased by 16%) in subjects with severe renal impairment (RI) compared with matched HS. No adverse events were reported during this study. CONCLUSIONS: Changes in the plasma exposure of total and unbound siponimod and metabolites M3 and M5 were not considered to be clinically relevant. Further to severe RI, investigation of PK in subjects with mild and moderate RI was not warranted..

Safety and Efficacy of Siponimod (BAF312) in Patients With Relapsing-Remitting Multiple Sclerosis: Dose-Blinded, Randomized Extension of the Phase 2 BOLD Study.[Pubmed:27380540]

JAMA Neurol. 2016 Sep 1;73(9):1089-98.

IMPORTANCE: This dose-blinded extension of the phase 2 BOLD (BAF312 on MRI Lesion Given Once Daily) Study in relapsing-remitting multiple sclerosis provides evidence on disease activity and safety of a range of siponimod doses for up to 24 months. OBJECTIVE: To assess the safety and efficacy of siponimod for up to 24 months during the dose-blinded extension of the BOLD Study. DESIGN, SETTING, AND PARTICIPANTS: At extension baseline in a randomized clinical trial, patients taking siponimod continued at the originally assigned dose and patients taking placebo were rerandomized to the 5 siponimod doses. Initial treatment was titrated over 10 days. A total of 252 eligible patients were treated at specialized multiple sclerosis centers for this study conducted from August 30, 2010, through June 3, 2013. INTERVENTIONS: Siponimod at 10-mg, 2-mg, 1.25-mg, 0.5-mg, and 0.25-mg doses. MAIN OUTCOMES AND MEASURES: Safety assessment included blood tests, documentation of adverse events at regular scheduled visits and Holter monitoring; key efficacy measures were annualized relapse rate and magnetic resonance imaging lesion activity. RESULTS: Among the 252 eligible patients, the mean (SD) ages were 37.2 (8.4) years, 35.2 (9.1) years, 34.0 (7.6) years, 35.1 (9.2) years, and 36.8 (9.1) years in the 0.25-mg, 0.5-mg, 1.25-mg, 2-mg, and 10-mg groups. Of the 252 patients, 184 (73%) entered the extension and received siponimod (10 mg: n = 33; 2 mg: n = 29; 1.25 mg: n = 43; 0.5 mg: n = 29; and 0.25 mg: n = 50); 159 (86.4%) completed the dose-blinded extension. The incidence of adverse events was similar across treatment groups (10 mg: 87.9%; 2 mg: 89.7%; 1.25 mg: 88.4%; 0.5 mg: 96.6%; and 0.25 mg: 84.0%). Nine patients reported serious adverse events (2 mg: 3/29 [10.3%], 1.25 mg: 1/43 [2.3%], 0.5 mg: 4/29 [13.8%], and 0.25 mg: 1/50 [2.0%]; no serious adverse event was reported for more than 1 patient and no new safety signals occurred compared with the BOLD Study. Dose titration mitigated symptomatic bradycardic events. Reductions in mean (95% CI) gadolinium-enhancing T1 lesion counts from the last BOLD assessment were sustained in the 10-mg, 2-mg, 1.25-mg, and 0.5-mg dose groups (0 [0-0], 0.1 [0-1.9], 0.1 [0-2.6], and 0.1 [0-2.8] at month 24, respectively). At the 3 highest vs 2 lowest doses, the estimated new/newly enlarging T2 lesion counts (95% CIs) were lower during months 6 to 12 (0.5 [0.2-1.3], 0.4 [0.2-1.1], and 0.2 [0.1-0.6] vs 1.3 [0.6-2.8] and 1.4 [0.7-2.7]), months 12 to 18 (0.4 [0.1-1.1], 0.4 [0.1-1.3], and 0.4 [0.2-1.0] vs 1.0 [0.4-2.6] and 3.6 [1.7-7.6]), and months 18 to 24 (0 [0-not estimable], 0.9 [0.1-7.6], and 0.1 [0-1.7] vs 1.6 [0.3-7.7] and 2.0 [0.4-9.5]). Annualized relapse rates (95% CIs) up to month 24 were similarly lower for the 3 highest doses: 0.22 (0.12-0.40) for 10 mg, 0.20 (0.10-0.38) for 2 mg, and 0.14 (0.08-0.26) for 1.25 mg vs 0.33 (0.19-0.56) for 0.5 mg and 0.33 (0.21-0.50) for 0.25 mg. CONCLUSIONS AND RELEVANCE: For up to 24 months of siponimod treatment, multiple sclerosis disease activity was low and there were no new safety signals; investigation in phase 3 trials is encouraged. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01185821.
