Background summary
This is a multicentre, randomised, double-blind, placebo-controlled, parallel
group trial to evaluate the efficacy and safety of arimoclomol 1200 mg/day (400
mg TID) over a 76 weeks* treatment period.
Patients diagnosed with ALS who had first appearance of symptoms (weakness)
within the previous 18 months will be eligible for screening.
In accordance with the eligibility criteria (Sections 5.2 and 5.3 of the study
protocol), subjects participating in the present trial may be on a stable
background treatment with riluzole. Additionally, a subset of up to 18 subjects
on stable (i.e. minimum 6 months*) treatment with edaravone and who otherwise
fulfil the eligibility criteria are planned for enrolment (see exclusion
criterion 5 in the study protocol).
Following confirmation of eligibility during the Screening/Baseline period (Day
-28 to Day 1), subjects will be randomised in a 2:1 ratio to receive either
arimoclomol 1200 mg/day (400 mg TID) or placebo orally TID. Randomisation will
be stratified by background riluzole use. The first post-baseline assessment
will take place in-person at the investigator site 4 weeks after the Baseline
visit; subsequent assessments will consist of a combination of in-person visits
and remote visits (telephone calls).
Subjects will attend the investigator site for an in-person visit on an
8-weekly basis for the initial 12 months of treatment (on Weeks 4, 12, 20, 28,
36, 44 and 52) and then for the following 6 months of treatment in-person
visits are scheduled on a 12-weekly basis until the end of treatment (on weeks,
64 and 76). Assessments will include those for efficacy and safety, as well as
sampling of biofluids for clinical safety laboratory tests, biomarkers, and PK
according to the schedule of procedures. If a subject is no longer able to
attend the site, appropriate trial site staff (e.g. nurse, sub-investigator as
required) will assess the subject by conducting a home visit.
On the remaining weeks of the treatment period (Weeks 8, 16, 24, 32, 40, 48,
56, 60, 68 and 72) a remote visit will be conducted by the subject receiving a
telephone call from the trial site staff. Assessments will therefore be limited
to efficacy and safety evaluations according to the schedule of procedures.
All visits should be scheduled within the visit window (+/- 7 days) relative to
the Baseline visit. Every effort should be made to ensure that the in-person
visits at Week 52 and Week 76 are arranged as close as possible to the
scheduled time-point.
An independent DMC will be established to monitor benefit. The DMC will act in
accordance with the DMC charter and may have access to unblinded data.
At any time during the trial, the IMP may be temporarily halted for up to 4
weeks for an intolerable AE. Following re-challenge at the intended dose,
de-escalation from 1200 mg/day (400 mg TID) to 600 mg/day (200 mg TID) may be
considered. The subject will continue on this decreased dose for the remainder
of the trial.
Subjects who discontinue treatment will be encouraged to attend all planned
visits as per protocol after drug discontinuation. Additionally, these subjects
will have remote visit 2 weeks after the premature IMP discontinuation.
If a subject reaches a trial survival endpoint (e.g. tracheostomy or PAV), the
IMP will be permanently discontinued. The subject will be offered to
participate in an open-label extension trial which will be conducted as a
separate trial.
Subjects who complete 76 weeks of randomised treatment will be offered
participation in a separate open-label extension which will be conducted as
separate clinical trial.
Study objective
Primary objective
To determine the efficacy of chronic treatment with arimoclomol 1200 mg/day
(400 mg TID) compared to placebo over 76 weeks in subjects with ALS as assessed
with Combined Assessment of Function and Survival (CAFS).
Secondary objective
To evaluate the impact of arimoclomol 1200 mg/day (400 mg TID) compared to
placebo on:
* Time to permanent assisted ventilation (PAV)/tracheostomy free survival
* Disease progression as measured by change from Baseline of the ALSFRS-R

Study design
A multicentre, randomised, double-blind, placebo-controlled, parallel group
trial to evaluate the efficacy and safety of arimoclomol 1200 mg (400 mg TID)
over a 76 weeks* treatment period
Screening period
Screening may be up to 4 weeks prior to Baseline if a washout period for an
investigational treatment is required. The minimum screening period is set as
one week for practical reasons (to ensure all results are available to
determine eligibility at Baseline).
Following confirmation of eligibility during the Screening/Baseline period (Day
-28 to Day 1), subjects will be randomised in a 2:1 ratio to receive either
arimoclomol 1200 mg/day (400 mg TID) or placebo orally TID. Randomisation will
be stratified by background riluzole use.
Treatment period
The first post-baseline assessment will take place in-person at the
investigator site 4 weeks after the Baseline visit; subsequent assessments will
consist of a combination of in-person visits and remote visits (telephone
calls).
Subjects will attend the investigator site for an in-person visit on an
8-weekly basis for the initial 12 months of treatment (on Weeks 4, 12, 20, 28,
36, 44 and 52) and then for the following 6 months of treatment in-person
visits are scheduled on a 12-weekly basis until the end of treatment (on Weeks
64 and 76).
On the remaining weeks of the treatment period (Weeks 8, 16, 24, 32, 40, 48,
56, 60, 68 and 72) a remote visit will be conducted by the subject receiving a
telephone call from the trial site staff.
If a subject is no longer able to attend the site, appropriate trial site staff
(e.g. nurse, sub-investigator as required) will assess the subject by
conducting a home visit.
At any time during the trial, the IMP may be temporarily halted for up to 4
weeks for an intolerable AE. Following re-challenge at the intended dose,
de-escalation from 1200 mg/day (400 mg TID) to 600 mg/day (200 mg TID) may be
considered. The subject will remain on this decreased dose for the remainder of
the trial.
End of treatment
Subjects who discontinue treatment will be encouraged to attend all planned
visits as per protocol after drug discontinuation.
An end-of treatment visit is to be conducted 2 weeks after last administration
of IMP in case of a) premature IMP discontinuation or b) subject completing
trial but not continuing into open label extension trial
End of trial
All randomised subjects will attend an end of trial visit.
If a subject reaches a trial survival endpoint (e.g. tracheostomy or PAV), the
IMP will be permanently discontinued. The subject will be offered to
participate in an open-label extension trial which will be conducted as a
separate trial.
Subjects who complete 76 weeks of randomised treatment will be offered
participation in a separate open-label extension trial through means of a
separate clinical trial protocol.
Intervention
Subjects found to be eligible will be randomised via the IWRS in a 2:1 ratio to
one of the following treatments:
a) Arimoclomol 1200 mg/day (400 mg TID)
b) Placebo (matching)
Treatment assignment will also be stratified by background treatment with
riluzole.
Study burden and risks
Adverse Effects of Arimoclomol
The study drug is in a research stage, so it may have adverse effects that are
not known in advance, there is a risk that rare or unexpected adverse effects
may occur. Arimoclomol may lead to an increase in serum creatinine levels in
blood and a decrease in mean creatinine clearance, which are laboratory signs
that show stress with the kidneys.
Placebo Risks
If the subject is in the group that is assigned to placebo (the medically
inactive substance), the ALS symptoms may not improve or may even worsen.
Allergic Reactions
There is a risk of allergic reaction. If the subject has a very serious
allergic reaction, she/he may be at risk of death. Some symptoms of allergic
reactions include an itchy rash (hives) or swelling of the throat making it
difficult to breathe.
Blood Sampling
The risks of giving blood include fainting and pain, bruising, swelling, or
rarely, infection where the needle was inserted. These discomforts are brief
and transient.
Electrocardiogram
The subject may experience skin irritation from the ECG electrode pads or pain
when removing the pads.
Lumbar Puncture
For most people, lumbar puncture does not cause any serious problems; the most
common side effect is headache which is often associated with fatigue and
dizziness. If this happens, the subject will be asked to lie down and drink
fluids, as well as to contact the investigator. If the headache does not go
away in a couple of days, it may be due to a spinal fluid leak from the
puncture site. This can be treated with a *blood patch* (a small amount of
your blood injected into the puncture site). Less common adverse effects
include pain at the place where the needle was inserted, back, neck, or
shoulder pain; these can be treated and usually improve over time. Other
complications such as low blood pressure, dizziness, bleeding into the spinal
canal or an infection of the spinal fluid are very uncommon, and may require
treatment in the hospital. In rare cases, the subject may experience pain in
the leg in connection with the sample retrieval, if the needle has hit a
nerve. The study doctor will discuss any risks with the patient.
Risks to an Unborn Child
Women
The subject may not take part in this study if she is breastfeeding, are
pregnant, think that she may be pregnant, or are trying to get pregnant. If
she is pregnant or breastfeeding, there may be risks to her and the baby that
are not known at this time. Women who can get pregnant will be tested for
pregnancy before and during the study, and must have a negative pregnancy test
at all clinic visits.
The subject must avoid getting pregnant in order to take part in this research
study.
Men
The study drug may harm an unborn child. The subject must inform his partner
of his participation in the study. The subject must agree not to have sexual
intercourse or to use contraception (condom) with or without spermicide in
addition to the birth control used by his partner during the study until 3
months after the last dose of the study drug.
If the subject thinks that his partner has become pregnant, he should, in
agreement with his partner, tell the study doctor at once. If his partner gets
pregnant during the study, he may be asked questions about the pregnancy and
the baby. The study doctor will request permission from his partner to collect
information regarding the pregnancy and the child.
Unknown Risks
There may be risks to the patient that are currently not known or cannot be
predicted.
The subject condition may worsen, remain the same, or improve as a result of
taking part in this research study.

(postmenarchal)* must agree not to intend to become pregnant and use a highly
effective method of contraception** during the trial through 1 month after the
last dose of trial medication. If the subject is a sexually active male with
female partners of child-bearing potential (postmenarchal) he must use a condom
with or without spermicide in addition to the birth control used by their
partners during the trial until 3 months after the last dose of trial
medication.
8. Stable dose of riluzole (50 mg twice daily) for a minimum of 14 days prior
to Day 1 (Baseline),or has not taken it for 14 days prior to Day 1.
Exclusion criteria
1. Tracheostomy or use of non-invasive ventilation for more than 2 hours during
waking hours at the time of Screening and Baseline visits.
2. Pregnant or breast-feeding.
3. Current or anticipated use of diaphragmatic pacing during the trial.
4. Exposure to any investigational treatment within 4 weeks or <5 half-lives of
the Screening visit, whichever is longest and/or advanced therapy medicinal
product (ATMP), i.e. treatments based on genes, cells or tissues and/or
participated in any prior ALS clinical trial receiving active drug treatment
(with the exception described in exclusion criterion 5).
5. Treatment with edaravone within 4 weeks of the Baseline visit. However, up
to 18 subjects on stable (i.e. minimum 6 months*) treatment with edaravone and
who otherwise fulfil the eligibility criteria are planned for enrolment
(limited to countries where edaravone has a marketing authorisation for
treatment of ALS).
6. Any of the following medically significant conditions:
a) Neurological impairment/dysfunction or unstable psychiatric illness that in
the investigator*s opinion is likely to interfere with assessment of ALS
disease progression.
b) Clinically significant unstable medical condition other than ALS, which
would present a risk to a subject to participate in the trial
c) Presence of dementia that impairs the ability of the subject to provide
informed consent, according to the PI decision.
d) Known or suspected allergy or intolerance to the IMP (arimoclomol or
constituents);
e) Chronic infection particularly HIV or Hepatitis B or C.
f) Clinically significant renal or hepatic disease
g) Aspartate aminotransferase and/or alanine aminotransferase, and/or lactate
dehydrogenase *3 times the upper limit of normal [ULN], bilirubin*2 times the
ULN, or creatinine *1.5 times the ULN). Laboratory tests may be repeated once
at Screening. Reasons to repeat laboratory tests may include that the
medication causing laboratory abnormality was suspended, any other suspected
cause may no longer exist, or to rule out laboratory error.
h) Cancer that is currently under active treatment or is likely to require
treatment during the trial that may alter the subject*s function and thereby
interfere with assessment of ALS disease progression.
i) Any other condition that in the investigator*s opinion would present a risk
to a subject to participate in the trial, interfere with the assessment of
safety or has an increased risk of causing death during the trial.
* Non child-bearing potential is defined as post-menopausal (minimum of 12
months with no menses and follicle-stimulating hormone in the post-menopausal
range) or sterilisation (hysterectomy, oophorectomy, or bilateral tubal
ligation).** Highly effective methods of contraception include combined
(oestrogen and progestogen containing) hormonal contraception associated with
inhibition of ovulation (oral, intravaginal, or transdermal); progestogen-only
hormonal contraception associated with inhibition of ovulation (oral,
injectable, or implantable); intrauterine device; intrauterine
hormone-releasing system; bilateral tubal occlusion; and vasectomised
partner.According to the recommendations from the Clinical Trial Facilitation
Group (CTFG, 2014), sexual abstinence is considered a highly effective birth
control method only if it is defined as refraining from heterosexual
intercourse during the trial until 1 week after the last dose of trial
medication (for female subjects of child-bearing potential) and for 3 months
after the last dose of trial medication (for male subjects with female partners
of child-bearing potential). The reliability of sexual abstinence needs to be
evaluated by the investigator in relation to the duration of the clinical trial
and the preferred and usual lifestyle of the subject.D29è*I*<
