药品介绍
首款遗传性视神经病变药物艾地苯醌 idebenone(商品名 Raxone)已获欧盟批准上市
2015年9月11日,欧盟委员会批准Santhera的首款药物Raxone(idebenone),用于Leber遗传性视神经病变(LHON)青少年及成年患者的视觉障碍治疗。这种罕见病症是一种遗传性的线粒体疾病,如果不进行治疗,它通常会使健康患者快速、深刻及永久性失明。
LHON是一种特别灾难性的疾病,因为遭受这种疾病的患者不健康,并通常比较年轻,他们在几个月内会迅速双眼失明。如果不进行治疗,多数患者仍会持续失明。
Raxone是一种口服药物,每天的用药剂量为900mg(每天三次,每次2片,随食物一起服用),用于青少年及成年 LHON 患者视觉障碍治疗。
作用机理
艾地苯醌(一种短链苯醌)是一种抗氧化剂,被认为能够将电子直接转移至线粒体电子传输链的复合物III,从而在复合物I缺乏的实验条件下规避了复合物I并恢复了细胞能量(ATP)的产生。 。类似地,在LHON中,艾地苯醌可将电子直接转移至电子传输链的复合物III,从而绕过复合物I,该复合物受所有引起LHON的三个主要mtDNA突变的影响,并恢复了细胞ATP的产生。
根据这种生化作用模式,艾地苯醌可能会重新激活LHON患者的存活但无活性的视网膜神经节细胞(RGC)。根据症状发作的时间和已经受影响的RGC的比例,艾地苯醌可以促进视力丧失患者的视力恢复。
适应症
Raxone适用于治疗Leber遗传性视神经病变(LHON)的青少年和成年患者的视力障碍。
用法用量
推荐剂量为艾地苯醌900毫克/天(300毫克,每天3次)。
对照临床试验尚无关于艾地苯醌连续治疗超过6个月的数据。
特殊人群
老年
对于老年患者,LHON的治疗无需特殊剂量调整。
肝或肾功能不全
肝或肾功能不全的患者尚未接受调查。建议对肝或肾功能不全的患者进行治疗。
小儿
尚未确定Raxone在12岁以下的LHON患者中的安全性和疗效。当前可用的数据在中进行了描述,但是无法提出关于本体论的建议。
给药方法
Raxone薄膜衣片应用水完全吞下。药片不应该被折断或咀嚼。由于食物会增加艾地苯醌的生物利用度,因此应与食物一起使用拉克酮。
禁忌症
对活性物质或所列的任何赋形剂过敏。
特别警告和使用注意事项
监控方式
应根据当地临床实践对患者进行定期监测。
肝或肾功能不全
在这些人群中没有可用的数据。因此,在给肝或肾功能不全的患者开具雷克斯酮处方时,应谨慎行事。
色度
艾地苯醌的代谢产物是有色的,并可能导致色尿,即尿液呈红棕色变色。这种作用是无害的,与血尿无关,并且不需要任何剂量调整或停止治疗。应谨慎行事,以确保色尿症不会掩盖由于其他原因(例如肾脏或血液疾病)而引起的颜色变化。
乳糖
Raxone含有乳糖。患有半乳糖不耐受,总乳糖酶缺乏症或葡萄糖-半乳糖吸收不良的罕见遗传病的患者不应服用雷克森。
夕阳黄
Raxone含有可能引起过敏反应的日落黄(E110)。
保质期

Raxone 150 mg film-coated tablets
Each film-coated tablet contains 150 mg idebenone. Excipients with known effect
Each film-coated tablet contains 46 mg of lactose (as monohydrate) and 0.23 mg of sunset yellow FCF (E110).
For the full list of excipients, see section 6.1.
Film-coated tablet.
Orange, round, biconvex film-coated tablet of 10 mm diameter, engraved with the Santhera logo on one side and ‘150’ on the other side.
4.1 Therapeutic indications
Raxone is indicated for the treatment of visual impairment in adolescent and adult patients with Leber’s Hereditary Optic Neuropathy (LHON) (see section 5.1).
Treatment should be initiated and supervised by a physician with experience in LHON. Posology
The recommended dose is 900 mg/day idebenone (300 mg, 3 times a day).
No data regarding a continuous treatment with idebenone beyond 6 months is available from controlled clinical trials.
Special populations
Elderly
No specific dose adjustment is required for the treatment of LHON in elderly patients.
Hepatic or renal impairment
Patients with hepatic or renal impairment have not been investigated. Caution is advised in treatment of patients with hepatic or renal impairment (see section 4.4).
Paediatric population
The safety and efficacy of Raxone in LHON patients under 12 years of age have not yet been established. Currently available data are described in sections 5.1 and 5.2, but no recommendation on posology can be made.
Method of administration
Raxone film-coated tablets should be swallowed whole with water. The tablets should not be broken or chewed. Raxone should be administered with food because food increases the bioavailability of idebenone.
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Monitoring
Patients should be regularly monitored according to local clinical practice. Hepatic or renal impairment
No data are available in these populations. Therefore, caution should be exercised when prescribing Raxone to patients with hepatic or renal impairment.
Chromaturia
The metabolites of idebenone are coloured and may cause chromaturia, i.e. a reddish-brown discoloration of the urine. This effect is harmless, not associated with haematuria, and does not require any adaptation of dose or discontinuation of treatment. Caution should be exercised to ensure that the chromaturia does not mask changes of colour due to other reasons (e.g. renal or blood disorders).
Lactose
Raxone contains lactose. Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take Raxone.
Sunset yellow
Raxone contains sunset yellow (E110) which may cause allergic reactions.
Data from in vitrostudies have demonstrated that idebenone and its metabolite QS10 do not exert systemic inhibition of cytochrome P450 isoforms CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6 and 3A4 at clinically relevant concentrations of idebenone or QS10. In addition, no induction of CYP1A2, CYP2B6 or CYP3A4 was observed.
In vivoidebenone is a mild inhibitor of CYP3A4. Data from a drug-drug interaction study in
32 healthy volunteers indicate that on the first day of oral administration of 300 mg idebenone t.i.d., the metabolism of midazolam, a CYP3A4 substrate, was not modified when both medicinal products were administered together. After repeated administration Cmax and AUC of midazolam were increased by 28% and 34%, respectively, when midazolam was administered in combination with 300 mg idebenone t.i.d. Therefore, CYP3A4 substrates known to have a narrow therapeutic index such as alfentanil, astemizole, terfenadine, cisapride, cyclosporine, fentanyl, pimozide, quinidine, sirolimus,
tacrolimus, or ergot alkaloids (ergotamine, dihydroergotamine) should be administered with caution in patients receiving idebenone.
Idebenone may inhibit P-glycoprotein (P-gp) with possible exposure increases of, e.g., dabigatran etexilate, digoxin or aliskiren. These medicines should be administered with caution in patients receiving idebenone. Idebenone is not a substrate for P-gp in vitro.
4.6 Fertility, pregnancy and lactation
Pregnancy
The safety of idebenone in pregnant women has not been established. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity. Idebenone should only be administered to pregnant women or women of child-bearing potential likely to become pregnant if it is considered that the benefit of the therapeutic effect outweighs any potential risk.
Breast-feeding
Available pharmacodynamic/toxicological data in animals have shown excretion of idebenone in milk (for details see 5.3). A risk to the suckling child cannot be excluded. . A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from Raxone therapy taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman.
Fertility
There are no data concerning the effect of exposure to idebenone on human fertility.
Raxone has no or negligible influence on the ability to drive and use machines.
Summary of the safety profile
The most commonly reported adverse reactions to idebenone are mild to moderate diarrhoea (usually not requiring the discontinuation of the treatment), nasopharyngitis, cough and back pain.

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V.
No report of overdose has been received from the RHODOS study. Doses up to 2,250 mg/day have been administered in clinical studies showing a safety profile consistent with that reported in section 4.8.
There is no specific antidote for idebenone. When needed, supportive symptomatic treatment should be given.
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Psychoanaleptics, Other psychostimulants and nootropics; ATC code: N06BX13
Mechanism of action
Idebenone, a short-chain benzoquinone, is an anti-oxidant assumed to be capable of transferring electrons directly to complex III of the mitochondrial electron transport chain, thereby circumventing complex I and restoring cellular energy (ATP) generation under experimental conditions of complex I deficiency. Similarly, in LHON idebenone can transfer electrons directly to complex III of the electron transport chain, thereby bypassing complex I which is affected by all three primary mtDNA mutations causing LHON, and restoring cellular ATP generation.
According to this biochemical mode of action, idebenone may re-activate viable-but-inactive retinal ganglion cells (RGCs) in LHON patients. Depending on the time since symptom onset and the proportion of RGCs already affected, idebenone can promote recovery of vision in patients who experience vision loss.
Clinical efficacy and safety
Clinical safety and efficacy of idebenone in LHON have been assessed in one double-blind, randomised, placebo-controlled study (RHODOS).
In RHODOS a total of 85 LHON patients, 14-66 years of age, with any of the 3 primary mtDNA mutations (G11778A, G3460A or T14484C) and disease duration of not more than 5 years were enrolled. Patients received either 900 mg/day Raxone or placebo for a period of 24 weeks (6 months). Raxone was given as 3 doses of 300 mg daily, each with meals.
The primary endpoint “best recovery of visual acuity (VA)” was defined as the result from the eye experiencing the most positive improvement in VA from baseline to week 24 using ETDRS charts. The main secondary endpoint “change in best VA” was measured as the difference between best VA in either the left or right eye at 24 weeks compared to baseline (Table 1).

||
Main secondary endpoint: Change in best VA (mean ± SE; 95% CI) |
logMAR –0.035 ± 0.046 |
logMAR 0.085 ± 0.060 |
logMAR –0.120, 6 letters (–0.255; 0.014) p=0.078 |
Analysis according to Mixed Model of Repeated Measures
One patient in the placebo group presented with ongoing spontaneous recovery of vision at baseline. Exclusion of this patient yielded similar results as in the ITT population; as could be expected, the difference between idebenone and placebo arm was slightly larger.
*logMAR - Logarithm of the Minimum Angle of Resolution
A pre-specified analysis in RHODOS determined the proportion of patients with an eye with baseline VA of ≤0.5 logMAR in whom the VA deteriorated to ≥1.0 logMAR. In this small subgroup of patients (n=8), 0 of 6 patients in the idebenone group deteriorated to ≥1.0 logMAR whereas 2 of 2 patients in the placebo group showed such a deterioration.
In a single-visit observational follow-up study of RHODOS VA assessments from 58 patients obtained on average 131 weeks after discontinuation of treatment indicates that the effect of Raxone may be maintained.
A post-hocresponder analysis was performed in RHODOS evaluating the proportion of patients who had a clinically relevant recovery of VA from baseline in at least one eye, defined as either: (i) improvement in VA from unable to read a single letter to able to read at least 5 letters on the ETDRS chart; or (ii) improvement in VA by at least 10 letters on the ETDRS chart. Results are shown in Table 2 including supporting data from 62 LHON patients using Raxone in an Expanded Access Programme (EAP) and from 94 untreated patients in a Case Record Survey (CRS).

In the EAP the number of responders increased with longer treatment duration, from 19 out of 62 patients (30.6%) at 6 months to 17 out of 47 patients (36.2%) at 12 months.
Paediatric population
In clinical trials in Friedreich’s Ataxia, 32 patients between the ages of 8 and 11 years and 91 patients between the ages of 12 and 17 years received idebenone at ≥ 900 mg/day for up to 42 months.
In RHODOS and the EAP in LHON, a total of 3 patients between the ages of 9 and 11 years and 27
patients between the ages of 12 and 17 years received idebenone at 900 mg/day for up to 33 months.
This medicinal product has been authorised under ‘exceptional circumstances’.
This means that due to the rarity of the disease it has not been possible to obtain complete information on this medicinal product.
The European Medicines Agency will review any new information which may become available every year and this SmPC will be updated as necessary.
5.2 Pharmacokinetic properties
Absorption
Food increases the bioavailability of idebenone by approximately 5-7-fold and therefore, Raxone should always be administered with food. The tablets should not be broken or chewed.
After oral administration of Raxone, idebenone is rapidly absorbed. On repeat dosing, maximum plasma concentrations of idebenone are reached on average within 1 hour (median 0.67 h range: 0.33-2.00 h).
Distribution
Experimental data have shown that idebenone passes the blood-brain barrier and is distributed at significant concentrations in cerebral tissue. Following oral administration pharmacologically relevant concentrations of idebenone are detectable in the aqueous humor of the eye.
Biotransformation
Metabolism occurs by means of oxidative shortening of the side chain and by reduction of the quinone ring and conjugation to glucuronides and sulphates. Idebenone shows a high first pass metabolism resulting in conjugates of idebenone (glucuronides and sulphates (IDE-C)) and the Phase I metabolites QS10, QS6, and QS4 as well as their corresponding Phase II metabolites (glucuronides and sulphates (QS10+QS10-C, QS6+QS6-C, QS4+QS4-C)). The main metabolites in plasma are IDE-C and QS4+QS4-C.
Elimination
Due to the high first-pass effect, the plasma concentrations of idebenone were generally only measurable up to 6 hours after oral administration of 750 mg Raxone, given either as a single oral dose or after repeated (14 days) t.i.d dosing. The main route of elimination is metabolism, with the majority of dose excreted via the kidneys as metabolites. After a single or repeated oral dose of 750 mg Raxone, QS4+QS4-C were the most prominent idebenone-derived metabolites in urine, representing on average between 49.3% and 68.3% of the total administered dose. QS6+QS6 represented 6.45% to 9.46%, whereas QS10+QS10-C and IDE+IDE-C were close to 1% or below.
Linearity/non-linearity
In phase I pharmacokinetic studies, proportional increases in plasma concentrations of idebenone were observed for doses from 150 mg to 1050 mg. Neither idebenone nor its metabolites showed time- dependent pharmacokinetics.
Hepatic or renal impairment
No data are available in these populations. Paediatric population
Whilst clinical trials experience in paediatrics with LHON is limited to patients of 14 years of age and above, pharmacokinetic data from population pharmacokinetic studies, which included paediatric Friedreich’s Ataxia patients of age 8 years and above, did not reveal any significant differences in the pharmacokinetics of idebenone.
Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential, toxicity to reproduction and development.

6. Contents of the pack and other information
Raxone contains a substance called idebenone.
Idebenone is used to treat vision impairment in adults and adolescents with an eye disease called Leber’s Hereditary Optic Neuropathy (LHON).
- This eye problem is inherited – this means it runs in families.
- It is caused by a problem with your genes (called a “genetic mutation”) that affects the ability of cells in the eye to produce the energy they need to work normally, so they become inactive.
- LHON can lead to loss of eyesight due to the inactivity of cells responsible for vision.
Treatment with Raxone can restore the ability of cells to produce energy and so allow inactive eye cells to work again. This can lead to some improvement in lost eyesight.
- if you are allergic to idebenone or any of the other ingredients of this medicine (listed in section 6).
Talk to your doctor or pharmacist before taking Raxone if:
- you have any blood, liver or kidney problems.
Change in urine colour
Raxone may make your urine become reddish brown. This change in colour is harmless – it does not mean your treatment needs to change. However, the change in colour could mean that you have
problems with your kidneys or bladder.
- Tell your doctor if your urine changes colour.
- He or she may do a urine check to make sure the change in colour is not hiding other problems.
Your doctor will check your eye-sight before you start taking this medicine and then at regular visits
while you are taking it.
This medicine should not be used in children This is because it is not known if Raxone is safe or works in patients under 12 years of age.
Some medicines may interact with Raxone. Tell your doctor if you are taking, have recently taken or
might take any other medicines, especially any of the following:
- antihistamines to treat allergies (astemizole, terfenadine)
- to treat heartburn (cisapride)
- to treat muscle and speech tics associated with Tourette syndrome (pimozide)
- to treat hearth rhythm disorders (quinidine)
- to treat migraine (dihydroergotamine, ergotamine)
- to put you to sleep called “anaesthetics” (alfentanil)
- to treat inflamation in rheumatoid arthritis and psoriasis (cyclosporine)
- to prevent the rejection of an organ transplant (sirolimus, tacrolimus)
- to treat strong pain called “opioids” (fentanyl)
If you are pregnant or breast-feeding, think you might be pregnant or are planning to have a baby, ask
your doctor for advice before taking this medicine.
- Your doctor will prescribe Raxone to you only if the benefits of the treatment are greater than the risks to the unborn child.
- Raxone may pass into the mother’s milk. If you are breast-feeding your doctor will discuss with
you whether to stop breast-feeding or to stop taking the medicine. This will take into account the benefit of breast-feeding to the child and the benefit of the medicine for you.
Raxone is not expected to affect your ability to drive or use machines.
- Raxone contains lactose (a type of sugar). If you have been told by your doctor that you have an
intolerance to some sugars, contact your doctor before taking this medicinal product..
- Raxone contains a colourant called “sunset yellow” (also called E110). This may cause allergic reactions.
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
The recommended dose is 2 tablets three times a day - this is a total of 6 tablets per day.
- Take the tablets with food - this helps to get more of the medicine from your stomach into your
blood.
- Swallow the tablets whole with a glass of liquid.
- Do not crush or chew the tablets.
- Take the tablets at the same time of day each day. For example in the morning at breakfast, with lunch at mid-day and with dinner in the evening.
If you take more Raxone than you should, talk to your doctor straight away.
If you forget a dose, skip the missed dose. Take the next dose at the usual time. Do not take a double dose to make up for a forgotten dose.
Talk to your doctor before you stop taking this medicine.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them. The following side effect may happen with this medicine:
Very common (may affect more than 1 in 10 people):
- nasopharyngitis (cold)
- cough
Common (may affect up to 1 in 10 people):
- diarrhoea (mild to moderate that usually does not require discontinuation of treatment)
