Methodology: 
This is a single-centre, open-label, non-randomised, single oral dose study in healthy male 
subjects. It is planned to enrol 6 subjects to ensure 4 evaluable subjects. 
Each subject will receive a single oral administration of a capsule containing 100 mg MD1003 
and not more than 2.22 MBq (approximately 60.0 µCi) [14C], in the fasted state. 
Study Design: 
Subjects will be screened to participate in the study up to 28 days before dosing. Subjects will 
be admitted to the clinical unit on the evening of Day -1 prior to investigational medicinal product 
(IMP) administration.

Subjects will be dosed on the morning of Day 1 following an overnight fast and will remain 
resident in the clinical unit until up to 168 h after dosing (up to Day 8). It is planned that subjects 
will be released as a group when all subjects have achieved a mass balance cumulative 
recovery of >90% or if <1% of the dose administered has been collected in urine and faeces 
within 2 separate consecutive 24 h periods. This may result in the subjects being discharged as 
a group prior to completion of the planned residency period. Once the discharge criteria or the 
planned residency period have been achieved, collection of all samples (blood, urine and 
faeces) will be stopped and the subjects will undergo discharge assessments. If the mass 
balance criteria have not been met by all subjects by Day 8, the residency period for the 
subjects not achieving the release criteria may be extended up to a maximum of an additional 
48 h (up to Day 10) for further collection of urine and/or faeces. If the release criteria have still 
not been met by Day 10, or if any additional residency is not considered appropriate or 
necessary, then home collections of urine and/or faeces may be requested at the discretion of 
the investigator for individual subjects.  
Number of Subjects Planned: 
It is planned to enrol 6 healthy male subjects to ensure data in 4 evaluable subjects. A subject 
will be considered evaluable if they have provided mass balance and PK samples for up to 72 h 
(up to Day 4) after IMP administration, or have demonstrated >90% mass balance recovery, or 
have <1% of the administered dose eliminated in excreta for 2 consecutive days, whichever is 
sooner. No replacement subjects are to be used in this study. 
Duration of Study: 
Single oral dose administration on a single occasion. The estimated time from screening until 
the end of the study is approximately up to 6 weeks. 
Main Inclusion Criteria: 
Healthy males aged 30 to 65 years. 
Body mass index (BMI) 18.0 to 30.0 kg/ m2. 
Investigational Medicinal Product, Dose and Mode of Administration: 
The following IMP will be used in this clinical study.

Metabolite Profiling and Identification 
Metabolite profiling of plasma, urine and faeces will be performed using liquid 
chromatography-radio-detection with subsequent mass spectrometry where appropriate. 
Identification of the chemical structure of each metabolite accounting for greater than 10% of 
circulating radioactivity in plasma (“AUC pool”) and accounting for greater than 10% of the 
administered dose in urine and faeces (from urine pools and faeces homogenate pools) will be 
performed. These aspects will be reported separately from the clinical study report as a 
standalone document.

Safety Assessments: 
The safety assessments to be conducted are: 
 
Adverse Events 
 
12-lead ECGs 
 
Vital Signs 
 
Clinical laboratory tests (clinical chemistry, haematology and urinalysis) 
 
Physical examinations 
Statistical Methodology: 
No formal statistical analysis will be performed for the safety, mass balance or PK data. 
Descriptive statistics (eg mean, standard deviation, median, minimum, maximum and number of 
subjects with an observation) are considered adequate for a study of this type. 
Sample Size and Power: 
The study is exploratory and no formal sample size calculation has been made. Based on 
experience from previous studies of a similar design, a total of 6 subjects is to be enrolled and a 
minimum of 4 evaluable subjects is considered sufficient.

Background Information 
5.1 
Introduction  
MD1003 is the code name for high doses of pharmaceutical-grade biotin being 
developed by MedDay Pharmaceuticals as a treatment for patients with primary and 
secondary progressive multiple sclerosis (MS). 
MD1003 is a powder of biotin in hard capsule (100 mg per capsule). The therapeutic 
dose of MD1003 is 300 mg/day (ie between 3 and 6 mg/kg/day) [1]. 
Biotin is a water-soluble vitamin acting as a carboxyl (CO2) transporter in carboxylation 
reactions. In mammals, biotin serves as a cofactor for four carboxylases involved in the 
metabolism of carbohydrates, amino acids and fatty acids: (1) pyruvate carboxylase 
(PC), (2) 3-methylcrotonyl-CoA carboxylase (MCC), (3) propionyl-CoA carboxylase 
(PCC) and (4) acetyl-CoA carboxylase (ACC) [2]. These carboxylases play a critical 
role in the intermediate metabolism of gluconeogenesis, fatty acid synthesis, and 
amino acid catabolism 
Of note, in the nervous system, ACC1 and ACC2 are detected exclusively in 
oligodendrocytes, the cells responsible for myelin synthesis, and are found in purified 
myelin, suggesting that these enzymes are key regulators of myelin synthesis [3]. 
Besides its role as a co-factor, biotin may regulate genes encoding enzymes or 
transporters involved in its own metabolism or other cell function [4]. However, this 
physiological role of biotin remains unclear. 
MD1003 is expected to be the first therapeutic approach having an impact on not active 
progressive MS by reversing the “virtual hypoxia” phenomenon and triggering 
remyelination [5],[6]. 
It was hypothesised that the positive effects of MD1003 that are seen in demyelinating 
diseases such as multiple sclerosis are linked to: (1) increased energy production 
through feeding the tricarboxylic acid (TCA) cycle in demyelinated neurons and in 
oligodendrocytes, and (2) stimulation of myelin repair through activation of the 
acetyl-CoA carboxylase in oligodendrocytes [6]. 
It is hypothesised that the treatment with MD1003 reverses the state of energy deficit 
through its role as a cofactor for PC, MCC, and PCC. All 3 of these enzymes are 
expressed in central nervous system (CNS) cells. These three biotin-dependent 
carboxylases generate intermediates for the TCA cycle at three different entry points: 
oxaloacetate, succinate and acetyl-CoA, and could be expected to increase the levels 
of cellular adenosine triphosphate (ATP). By increasing the available intraneuronal pool 
of ATP, high-dose biotin may reduce demyelinated neural dysfunction and the adverse 
effects of hypoxia. 
A second biotin-dependent pathway that occurs in the cytoplasm through the 
biotin-dependent ACC1 and ACC2 may play a role in myelin repair. This pathway is 
key in the regulation of fatty acid synthesis [2]. ACC1 and ACC2 are key regulators of 
membrane lipid synthesis including myelin synthesis [3]. In the CNS, ACC1 and ACC2 
are mostly expressed in oligodendrocytes [3]. Furthermore, ACC can be detected in 
purified myelin [3].

As 
other

demyelinating 
diseases 
and

share 
the 
pathophysiological mechanisms that are thought to be targeted by MD1003, it is 
expected that MD1003 would be beneficial in these diseases such as some 
demyelinating neuropathies and adrenomyeloneuropathy.

Previous Study Findings 
The non-clinical and clinical studies conducted for MD1003 are summarised below; 
further details are provided in the Investigator’s Brochure [1]. 
5.3.1 Non-clinical Findings 
The hypothesised positive effects of MD1003 that may be seen in demyelinating or 
dysmyelinating diseases such as MS are thought to be linked to: (1) increased energy 
production through augmenting the TCA cycle in demyelinated neurons, and 
(2) stimulation of myelin repair through activation of the acetyl-CoA carboxylase in 
oligodendrocytes.

Following oral administration, biotin is absorbed in the intestine via the sodium 
multivitamin transporter (SMVT). At the therapeutic dose level, biotin has good oral 
bioavailability (~50%) and is largely not bound to plasma proteins. Following an oral 
administration of MD1003 in rats, the highest concentrations were found in the 
stomach, bladder, and kidneys with a rapid elimination with very low concentrations 
after 24 h and no storage of biotin observed. Biotin uptake into the CNS, liver, and 
most peripheral tissues also involves the SMVT. No saturation of the SMVT at the 
blood-brain barrier is expected at the therapeutic dose. Biotin may accumulate in the 
placenta and is excreted in milk in animals. Biotin is catabolized mostly in the liver via 
2 pathways leading to 2 main metabolites, bisnorbiotin and biotin sulfoxide. Biotin 
metabolites are inactive. Following an intravenous administration of MD1003 in rats, 
biotin and its metabolites are rapidly excreted in the urine (>80% of elimination) with 
biotin being the major form excreted. Urinary clearance data obtained following 
administration of MD1003 in healthy volunteers suggest that biotin is actively secreted 
by the kidneys. 
Drug interaction with MD1003 treatment involving cytochrome P450 enzymes or 
transporters commonly involved in the absorption, metabolism and elimination of other 
drugs are not expected. The expected risk of drug interaction with MD1003 
administration in humans resides mainly from pharmacodynamic interaction with insulin 
and pharmacokinetic (PK) interactions with other substrates of the biotin transporter 
(SMVT) and some antiepileptic drugs (carbamazepine, oxcarbazepine, primidone, and 
valproate semisodium). 
Based on the safety profiles of MD1003 in rats and dogs following repeated 
administrations, there is no identified toxicity associated with MD1003 using doses 
resulting in up to 8-fold the plasmatic exposure corresponding to the MS trial doses of 
100 mg orally 3 times daily (TID). MD1003 did not reveal any untoward effect on the 
CNS, respiratory, cardiovascular, hepatic or renal functions. In several studies, 
MD1003 did not demonstrate genotoxic potential. This combined with the absence of 
genotoxicity or carcinogenicity in literature reports suggest that biotin is unlikely to 
present a risk for carcinogenicity. No carcinogenicity studies have been conducted with 
MD1003, but a 2-year study in rats and a 6-month study in transgenic rasH2 mice are 
ongoing. A teratogenic effect of MD1003 was observed in pregnant rabbits at a dose 
equivalent to twice the exposure in humans in the absence of maternal toxicity. No 
teratogenic effect was observed in rats. However, the risk of teratogenicity observed in 
rabbits cannot be excluded in humans at the MD1003 therapeutic dose. Oral doses of 
MD1003 did not result in epithelial irritation and is not expected to have allergic 
potential. 
5.3.2 Clinical Findings 
MD1003 is currently in Phase III of clinical development for the treatment of 
progressive MS. At the date of the last update of the Investigator’s Brochure (cut-off 
date 18 Jan 2019), a total of 1,145 patients or healthy volunteers had been randomised 
in 11 studies (ongoing or completed) in the MD1003 clinical program. Of the 
1,145 subjects/patients, a total of 493 had been exposed to MD1003 and for 
642 patients with progressive MS (Phase III study), treatment groups are still blinded. 
In addition, an early access program for MD1003 (ATUc; Autorisation Temporaire 
d’Utilisation de cohorte) is ongoing in France since July 2016 with MD1003 
administered in patients with progressive MS.

A total of 9,661 patients were included in the ATUc between 13 Jul 2016 and 
12 Jan 2019 representing 12,241 patients-years of exposure. 
A Phase I program with 4 studies assessing the safety and PK profile of MD1003 has 
been completed. A total of 124 healthy volunteers have been randomised to date. 
MD1003 daily doses ranged from 100 to 600 mg, with treatment duration of up to 
8 days. No deaths, adverse events (AEs) or serious adverse events (SAEs) leading to 
treatment discontinuation with MD1003 were reported in these 4 healthy volunteer 
studies. 
Two Phase II studies were conducted in which 30 patients with amyotrophic lateral 
sclerosis and 15 patients with demyelinating neuropathies were included with a daily 
dose of 300 mg (100 mg TID) MD1003. 
A total of 5 Phase IIb-III or Phase III studies are ongoing or completed with MD1003 in 
Europe and Lebanon at the dose of 300 mg per day (100 mg TID) in patients with 
progressive MS (830 patients) and adrenomyeloneuropathy (60 patients). Further 
details can be found in the Investigator’s Brochure [1]. 
5.3.2.1 
Safety 
Two large randomised, double blind, placebo-controlled Phase IIb-III studies have been 
conducted in patients with MS; 65 patients in study MS-ON for up to 6 months and 
103 patients in study MS-SPI received 100 mg MD1003 TID for up to 12 months. Both 
studies have open label extension phases which are ongoing. The most commonly 
reported adverse events (>5% of patients) after treatment with MD1003 in these 2 
completed randomised, double-blind, placebo-controlled studies, regardless of 
assessment of relationship to study treatment were nasopharyngitis, urinary tract 
infection, worsening of signs and symptoms of MS and MS relapse. The majority of 
reported adverse events were mild to moderate. Reported SAEs are consistent with the 
conduct of a trial in an MS patient population.  
In completed studies with MD1003, a total of 4 serious adverse events (SAEs), 
reported in 4 patients and considered by investigators as being related to the study 
drug were reported. These SAEs included mucocutaneous rash, hypoglycaemia, 
transient myopathy and laboratory test interference. 
In ongoing studies, one SAE (rash maculo-papular) in one patient with amyotrophic 
lateral sclerosis was considered as related to MD1003 by the investigator. 
No deaths, SAEs, or AEs leading to treatment discontinuation with MD1003 were 
reported in the 4 healthy volunteer studies with MD1003 administered at doses up to 
600 mg. 
Based on MD1003 clinical and non-clinical data available, as well as the corpus of 
scientific and medical literature related to biotin, the following safety issues have been 
identified in patients treated with MD1003: interference with laboratory tests based on a 
biotin/streptavidin interaction, for which minimisation measures are in place (trial 
participation card and referral letter to general practitioner/hospital stating the subject 
has received a high biotin dose if a subject if withdrawn early), and a potential risk of 
teratogenicity observed in animal studies (rabbits). Since this study involves a single 
dose of biotin and subjects are planned to be discharged only after the administered 
dose has been eliminated, risk due to interference with laboratory results is considered

to be very low and will be considered only if subjects are withdrawn early. In the case 
of early withdrawal, the risk minimisation measures above will be applied In addition, 
some local allergic skin reactions have been observed. A single case of hypoglycaemia 
in an insulin-dependent patient and a single case of transient myopathy have also been 
reported in clinical trials. Adverse drug reactions reported in clinical trials to date are 
provided in Table 2.

a One patient (0.4%) with insulin-dependent diabetes experienced hypoglycaemic episodes, which 
occurred in the open-label phase of the studies approximately 1 year after initiation of MD1003. Episodes 
ceased when MD1003 was stopped and recurred on re-challenge. 
b During treatment with MD1003 in the double-blind placebo-controlled phases of the clinical studies, 
1 (0.6%) patient developed a mucocutaneous rash, 1 (0.6%) patient cutaneous blisters and 
1 (0.6%) patient eczema. No patients in the placebo group reported these events. 
c One (0.4%) patient developed transient myopathy, which occurred in the open-label phase of the studies 
5 months after initiation of MD1003. The patient fully recovered when MD1003 was stopped. 
d Uncommon frequency category defined as ≥1/1000 to <1/100. 
No serious adverse reactions have been listed as expected so far [1]. 
The safety profile of MD1003 is favourable, supporting the continuation of the clinical 
investigations program for the treatment of MS as planned. 
5.3.3 Efficacy 
An open label pilot study was conducted in MS patients (n=23) using high doses of 
biotin and demonstrated that biotin could favourably effect disease progression in 
patients with progressive MS [5]. 
MS-SPI Trial: The Multiple Sclerosis-Spinal (MS-SPI) study (randomised double-blind 
study) was conducted to demonstrate the superiority of MD1003 300 mg/day over 
placebo in patients with progressive MS (n=154). The primary outcome measure was 
the proportion of patients who demonstrated improvement in a composite measure of 
Expanded Disability Scale Status (EDSS) and timed 25-foot walk. The primary 
endpoint was reached with 13 (12.6%) patients treated with MD1003 who achieved 
clinical improvement in MS-related disability at month 9, confirmed at month 12, 
compared with none of the placebo-treated patients (p=0.0051). Results of clinician 
and patient global impression of change measure (CGI/SGI) also showed statistically 
significant differences in favour of the MD1003 group. The mean change EDSS was 
stable in MD1003 treated patients while it progressively worsened in placebo active 
arms and compared to previous published studies (p=0.69) [7]. An open label 
extension study continues.

MS-ON Trial: The effect of MD1003 in MS patients with permanent visual loss 
following optic neuritis (ON) was assessed in another controlled clinical study, MS-ON, 
enrolling 93 patients. Following a 6-month treatment, there was no clinically significant 
difference between the MD1003 group and the placebo group, with no increase in the 
mean change of visual acuity in all groups. A positive trend was observed in the 
progressive optic neuropathy subgroup (n=31), which is consistent with findings of 
Study MS-SPI, where MD1003 showed efficacy in patients with a progressive form of 
MS [8]. 
These results support that targeting neuron/oligodendrocyte metabolism represents a 
novel disease modifying therapy approach in progressive MS. 
Overall, results of the double-blind and extension phases of MS-SPI and MS-ON 
studies showed a benign safety profile and suggest a durable treatment effect of 
MD1003 in patients with progressive MS. 
A larger international randomised placebo-controlled trial (SPI2) is ongoing in patients 
with progressive MS. 
5.3.4 
Pharmacokinetics and Product Metabolism in Animals 
Full details of PK and absorption, metabolism, distribution and elimination (ADME) data 
can be found in the Investigator’s Brochure [1]. 
In the GLP Study MD1003-ADME-RAT, the radioactivity was rapidly eliminated from 
plasma after intravenous administration of 10 mg/kg 
14C-MD1003. After oral 
administration of 30 mg/kg 14C-MD1003 (human equivalent therapeutic dose), the 
radioactivity was rapidly absorbed and after a first phase of rapid elimination from the 
plasma, the radioactivity was then slowly eliminated. 
At physiological doses of [14C] biotin (88 nmol/kg body weight) given orally to pigs, the 
plasma concentration profile best fitted a tri-exponential equation [9], which 
corresponds to a tricompartmental open model. Disappearance curves of total 14C and 
of [14C] biotin were similar. Biotin pharmacokinetics after intravenous injection of [14C] 
biotin was marked by a very short half-life of the initial distribution phase (7 min), 
followed by a slower plasma elimination phase (T1/2, β of 1.43 h) and a long apparent 
terminal half-life T1/2, γ estimated at 22 h. The rapid initial distribution phase was 
shown to correspond to the disappearance of biotin from the plasma (central 
compartment) to the peripheral compartments, such as the total body water pool or 
tissue pools [9]. 
The retention over many days of a substantial portion of the administered dose may 
occur as a consequence of the metabolic trapping of biotin into cells: conversion of 
biotin to intermediates such as biotinyl-adenosine monophosphate and biotinyl-CoA, or 
binding of biotin to proteins such as carboxylases and histones [9]. The half-life of 
pyruvate carboxylase was determined to be 28 h and 4.6 days for acetyl-CoA 
carboxylase [10]. 
Overall, PK data obtained with MD1003 confirmed the literature data and completed 
the PK properties of biotin: 
 
Biotin is rapidly absorbed by the oral route in animals

 
At the equivalent therapeutic dose in rats (30 mg/kg), biotin is not completely 
absorbed 
 
At very high doses (up to 3000 mg/kg), plasma exposure does not significantly 
increase, suggesting that the transport is saturated 
 
The major route of elimination is urinary and most of the biotin is excreted 
unchanged 
 
There was no evidence of accumulation after once daily repeated dosing in animals 
6 
Rationale 
6.1 
Study Rationale 
This study is being conducted to investigate the oral PK, mass balance and metabolite 
profiling and identification of [14C]-MD1003. 
6.2 
Dose Rationale 
The therapeutic daily dose of biotin is 300 mg given as 100 mg TID; therefore, a 
100 mg single does is considered the appropriate dose to investigate in an ADME 
study. This dose is not expected to result in any significant adverse effects in a healthy 
volunteer population.  
The dose of radioactivity has been determined following review of human dosimetry 
calculations provided by Public Health England (PHE). The associated radiation 
exposure will fall within International Commission on Radiological Protection (1992) 
Guidelines for Category IIa studies (0.1 to 1 mSv). The dose of radioactivity will be no 
more than 2.22 MBq (60.0 µCi). 
To ensure that the [14C] drug product(s) does not exceed the limit for radioactive dose 
approved by the Administration of Radioactive Substances Advisory Committee 
(ARSAC), the target specific activity of the drug substance will be set at 95% of 90% of 
the threshold radioactive dosing limit. This takes into account the allowed tolerances 
during the manufacture of the drug product (± 5% range and drug substance ± 10% 
range). This provides continued assurance for compliance with the ARSAC-approved 
limit for drug product radioactivity dose. 
6.3 
Population Rationale 
As this is a Phase I study assessing the mass balance, PK and safety of MD1003, the 
most relevant population is healthy volunteers. Subjects who are non-smokers without 
a history of alcohol or drug abuse are proposed to avoid interaction on drug 
metabolism and to avoid non-compliance.  
We acknowledge the ARSAC Notes for Guidance recommend that wherever possible, 
healthy subjects selected for research projects should be aged over 50 years [11]. 
However, the current study is designed to generate data for supporting the 
investigation of the human ADME of a drug, as well as generating samples for 
metabolite profiling and structural identification.

There are 2 main reasons for generating these data within a clinical development 
programme. The first is to provide human metabolite data that can be used to interpret 
the metabolism profiles seen in the preclinical species employed in the longer term 
toxicity studies, to ensure that there is adequate toxicology coverage for the safe 
development of the drug in patients. The second is to provide data to understand how 
the drug is processed in physiologically normal subjects, because understanding the 
routes of metabolism and elimination in a healthy population generates the appropriate 
data to guide the clinical pharmacology package required to fulfil the regulatory 
requirements of a New Drug Application.  
In order to address these 2 main aims of an ADME study, investigation of the drug 
under development is required in a population with normal physiological function, as it 
is recognised that certain physiological processes eg renal function, deteriorate with 
age and therefore it is preferable to use as healthy as possible population, to mitigate 
against factors which may make interpretation of the data difficult. Also, healthy 
subjects as a trial population are ideal since they have a relatively stable physiological, 
biochemical and hormonal status, which removes any disease-related variations and 
variations due to concomitant medications. Therefore given the aims of this ADME 
study our target age range for this study will be 30 to 65 years. 
Based on the above considerations, including the risk of teratogenicity (see 
Section 5.3.1) in rabbits that cannot be excluded in humans and risks associated with 
radiation exposure, and to ensure homogeneity of the population, healthy male 
subjects, aged 30 to 65 years are considered suitable for this study. 
6.4 
Risks and Benefits 
Adverse drug reactions from the MS-SPI and MS-ON studies in MS patients reported in 
the Investigator’s Brochure [1] are listed in Table 2. There are no expected serious 
adverse reactions for either healthy volunteers or patients administered MD1003. It is 
unlikely that healthy volunteers administered a single 100 mg dose of MD1003 will 
experience an adverse reaction. Adverse events will be treated symptomatically, if 
required. 
The dosage form will contain a radionuclide (NMT 2.22 MBq [60.0 µCi] 14C), so 
subjects will be exposed to ionising radiation. The effective dose that each subject will 
receive from one administration will not exceed 1 mSv. This is approximately 4.5 
months of the average radiation exposure received in the UK each year (2.7 mSv; data 
obtained from PHE Ionising Radiation Exposure of the UK Population: 2010 Review). 
This equates to slightly more than the radiation dose that would result from 2 X-rays of 
the abdomen. It is believed that any increase in the amount of radiation that is received 
above natural radiation carries a risk of later developing serious and possibly fatal 
conditions. The risk associated with the maximum possible dose of radiation in this 
study is very small indeed and is considered to be acceptable.  
Collecting a blood sample from a vein may cause pain, swelling, bruising, 
light-headedness, fainting, and very rarely, clot formation, nerve damage and/or 
infection at the site of the needle stick. 
During cannulation, more than one attempt may be needed to insert the cannula in a 
vein of a subject and it is possible that bruising and/or inflammation may be 
experienced at the site of cannulation.

Electrocardiogram stickers on the subjects' chests and limbs may cause some local 
irritation and may be uncomfortable to remove but subjects will be closely monitored to 
ensure any local irritation does not persist. 
There is no benefit to the subjects from taking part in this study. The development of a 
product to treat MS will be of benefit to the wider community/patients with this disease. 
The overall risk benefit balance is therefore considered to be acceptable.

Study Design 
8.1 
Study Plan 
This is a single-centre, open-label, non-randomised, single oral dose study in healthy 
male subjects. It is planned to enrol 6 subjects to ensure 4 evaluable subjects. 
Each subject will receive a single oral administration of a capsule containing 100 mg 
MD1003 and NMT 2.22 MBq (approximately 60.0 µCi) [14C], in the fasted state. 
The study design is presented in Figure 1. Subjects will be screened to participate in 
the study up to 28 days before dosing. Subjects will be admitted to the clinical unit on 
the evening of Day -1 prior to IMP administration.

Subjects will be dosed on the morning of Day 1 following an overnight fast and will 
remain resident in the clinical unit until up to 168 h after dosing (up to Day 8). It is 
planned that subjects will be released as a group when all subjects have achieved a 
mass balance cumulative recovery of >90% or if <1% of the dose administered has 
been collected in urine and faeces within 2 separate consecutive 24 h periods. This 
may result in the subjects being discharged as a group prior to completion of the 
planned residency period. Once the discharge criteria or the planned residency period 
has been achieved, collection of all samples (blood, urine and faeces) will be stopped 
and the subjects will undergo discharge assessments. If the mass balance criteria have 
not been met by all subjects by Day 8, the residency period for the subjects not 
achieving the release criteria may be extended up to a maximum of an additional 48 h 
(up to Day 10) for further collection of urine and/or faeces. If the release criteria have 
still not been met by Day 10, or if any additional residency is not considered 
appropriate or necessary, then home collections of urine and/or faeces may be 
requested at the discretion of the investigator for individual subjects.

a Subject may be discharged as a group earlier if a cumulative recovery of >90% has been achieved or if 
<1% of the dose administered has been collected in urine and faeces within 2 separate consecutive 24 h 
periods. If the criteria are not met by Day 8, this may result in the extension of the residency period for the 
subjects not achieving the release criteria up to a maximum of an additional 48 h (up to Day 10) for further 
collection of urine and/or faeces. If the criteria are still not met by Day 10, or if additional residency is not

the discretion of the investigator for individual subjects.  
8.2 
Criteria for In-Study Decisions 
Not applicable for this study. 
8.3 
Subject Withdrawal 
If a subject wishes to leave the study at any time, they will be permitted to do so. Every 
reasonable effort will be made by Quotient Sciences to complete a final 
assessment/discharge procedures. Quotient Sciences will advise the sponsor of the 
withdrawal of any subject from the study.

Early withdrawal is defined as the date of the decision to withdraw the subject from the 
study. Subject completion is defined as the date of the last procedure conducted or last 
contact (ie phone call) for that subject. 
If a subject requests to leave the clinical unit earlier than the planned discharge time 
eg due to unforeseen personal circumstances, but aims to return to the clinical unit to 
complete the study, this will be documented as a subject self-discharge and a protocol 
deviation. The subject must complete the planned assessments/discharge procedures 
before discharge from the clinical unit and will return for the next study 
period/assessments, as planned.  
Subjects will be withdrawn from the study drug(s) for the following reasons: 
 
Experiencing a serious or severe AE including but not limited to: 
− corrected QT interval by Fridericia’s formula (QTcF) of >500 msec or 
increase in QTcF interval of >60 msec from baseline (confirmed following 
a repeat ECG) 
− alanine aminotransferase (ALT) concentration >3 × the upper limit of the 
reference range (confirmed following a repeat ALT blood test) 
 
Experiencing a 25% decrease in creatinine clearance (CLcr) 
 
Termination of the study 
 
Upon the subject’s request (withdrawal of consent) 
 
Significant deviation from the protocol 
 
Concurrent illness that would compromise subject safety of study data 
interpretation or requirement for prohibited medication 
 
At the discretion of the investigator 
For the purpose of withdrawal criteria, baseline will be considered as pre-dose Day 1 
measurement. 
For a subject who withdraws because of an IMP-related AE, every effort will be made 
to ensure the subject completes follow-up procedures.  
Early termination of the study will be distinguished from withdrawal of consent by the 
subject to participate in any further activities. 
8.4 
Subject Replacement 
No replacement subjects are to be used in this study. 
A subject will be considered evaluable if they have provided mass balance and PK 
samples for up to 72 h (up to Day 4) after IMP administration, or have demonstrated 
>90% mass balance recovery, or have <1% of the administered dose eliminated in 
excreta for 2 consecutive days, whichever is sooner. 
8.5 
Stopping Criteria 
The study will be halted, and the risk to other subjects evaluated if any of the following 
criteria are met:  
 
A serious adverse reaction (ie a serious AE considered at least possibly related to 
the IMP administration) in one subject. 


Sponsor/Quotient Sciences Confidential 
 
Protocol MD1003CT2019-03MB (QSC201639) Version 1.0 
12 SEP 2019 
Page 27 of 54  
 
 
Severe non-serious adverse reactions (ie severe non-serious AE considered as, at 
least possibly related to the IMP administration) in two subjects in the same cohort, 
independent of within or not within the same system organ class. 
Relatedness will be determined by the investigator.  
If the study is halted, a temporary halt will be submitted to the Medicines and 
Healthcare products Regulatory Agency (MHRA) and ethics committee (EC) in the form 
of a substantial amendment. The study may be resumed or terminated; however, it will 
not be resumed until a further substantial amendment to resume the study is submitted 
and approved by MHRA and EC. 
The ARSAC Practitioner will also be informed of the temporary halt. 
8.6 
Study Termination 
After the start of protocol activities but prior to the commencement of dosing, the study 
may be terminated by the sponsor and investigator without consultation with the 
MHRA, EC and ARSAC practitioner or ARSAC. The end of the trial must be notified to 
the MHRA and EC immediately and at the latest within 15 days after the study is 
terminated, clearly explaining the reasons. A description of any follow-up measures 
taken for safety reasons if applicable, will also be provided. The ARSAC Practitioner 
and ARSAC will also be notified within an appropriate timeframe. 
If the study is abandoned prior to commencement of any protocol activities, the PI or 
sponsor must notify the EC, MHRA, ARSAC practitioner and ARSAC (if ARSAC 
research application has been submitted or approved) in writing outlining the reasons 
for abandonment of the trial. 
Once exposure to ionising radiation has begun, the study will be completed as planned 
unless the following criteria are satisfied that require a temporary halt or early 
termination of the study. 
 
The occurrence of serious or severe adverse event(s), as defined in Section 8.5, if 
considered to be related to the IMP, as defined in Section 14.2. 
 
New information regarding the safety of the IMP that indicates a change in the 
risk/benefit profile for the compound, such that the risk/benefit is no longer 
acceptable for subjects participating in the study. 
 
Significant violation of Good Clinical Practice (GCP) that compromises the ability to 
achieve the primary study objectives or compromises subject safety. 
If any of the above occurs, the study will be terminated if careful review of the overall 
risk/benefit analysis described in Section 6.4 demonstrates that the assumptions have 
changed and that the overall balance is no longer acceptable. In these circumstances 
termination can only take place with the agreement of the investigator and sponsor. 
The MHRA, EC, ARSAC practitioner and ARSAC will be informed of study termination. 
If it becomes necessary to consider termination of the study on the dosing day, dosing 
may be suspended pending discussion between the investigator, sponsor and ARSAC 
practitioner. Dosing will be stopped immediately on safety grounds. 
The study may be terminated or suspended at the request of the MHRA or EC.

8.7 
Treatment Allocation 
This is an open-label, non-randomised study, therefore a randomisation schedule will 
not be produced. A treatment allocation will be produced prior to dosing with IMP, 
which will dictate the order in which the treatments should be administered to each 
subject. The treatment allocation will be retained in the Investigator Site File. 
8.7.1 Subject Numbers 
Subject numbers will be allocated on the morning of dosing according to the code 001 
to 006 using the lowest number available.  
8.7.2 Blinding  
This is an open-label, non-randomised study and therefore blinding is not required. 
9 
Selection of Subjects 
Quotient Sciences must have a full medical history from each subject’s general 
practitioner (GP) within the last 12 months, prior to enrolment for the study.  
Subjects will be recruited from the Quotient Sciences panel or by direct advertising to 
the public.  
Before subjects are admitted to the clinical unit, The Over Volunteering Prevention 
System will be checked to ensure that each subject has not participated in a study at 
another site within at least 90 days of the dosing date. 
9.1 
Informed Consent 
Subjects will be provided with a written explanation of the study at least the day before 
the screening visit. A physician or nurse will explain to each subject the nature of the 
study, its purpose, expected duration and the benefits and risks involved in study 
participation. Subjects will be informed that, for safety reasons, brief details of their 
involvement in the study may be revealed to other units and companies that carry out 
clinical studies in the local area. Subjects will then be given the opportunity to ask 
questions and will be informed of their right to withdraw from the study without 
prejudice. After this explanation and before entering the study, the subject will 
voluntarily sign an informed consent form (ICF). Until written consent has been 
obtained from the subject no study specific procedure or investigation will be 
performed. If an amendment is made to the participant information sheet (PIS), 
participants will be re-consented to the most current version of the ICF(s) where 
appropriate. 
9.2 
Inclusion Criteria 
1. Healthy males 
2. Age 30 to 65 years of age at the time of signing informed consent

Exclusion criteria 6, 7, 9, 10, 12, 13, 18, 19, 20, 21 and 22 from the list above will be 
re-assessed at admission/pre-dose. 
Healthy subjects who do not meet the inclusion/exclusion criteria for the study will not 
be enrolled. 
9.4 
Contraception 
Male subjects who are sexually active with a partner of child bearing potential must 
use, with their partner, a condom plus an approved method of effective contraception 
from the time of informed consent until 90 days after IMP administration. 
The following methods are acceptable: 
 
Partner’s use of combined (oestrogen and progestogen-containing) hormonal 
contraception associated with inhibition of ovulation:  
− oral  
− intravaginal  
− transdermal  
 
Partner’s use of progestogen-only hormonal contraception:  
− oral  
− injectable/implantable 
− intrauterine hormone-releasing system  
 
Partner’s use of intrauterine device  
 
Surgical sterilisation (for example, vasectomy or partner’s bilateral tubal occlusion) 
 
Partner’s use of female cap or diaphragm or sponge with spermicide (double 
barrier) 
Alternatively, sexual abstinence is considered a highly effective method only if defined 
as refraining from heterosexual intercourse during the entire period of risk associated 
with the study treatments. The reliability of sexual abstinence needs to be evaluated in 
relation to the duration of the clinical trial and the preferred and usual lifestyle of the 
subject. 
These contraception requirements are aligned with guidance issued by the Heads of 
Medicines Agency: Clinical Trials Facilitation Group [12]. 
9.4.1 Exposure to Sexual Partners During the Study 
There is a significant risk of drug exposure through the ejaculate (which also applies to 
vasectomised males) that might be harmful to sexual partners (both male and female), 
including pregnant partners of male subjects. Therefore, a condom should be used by 
all male subjects throughout the study and for 90 days after IMP administration.  
9.4.2 Sperm Donation 
Male subjects should not donate sperm for the duration of the study and for 90 days 
after IMP administration.

9.5 
Pregnancy 
Subjects will be instructed that if their partner becomes pregnant during the study this 
should be reported to the investigator. The investigator should also be notified of 
pregnancy occurring during the study but confirmed after completion of the study. In 
the event that a subject’s partner is subsequently found to be pregnant after the subject 
is included in the study, then consent will be sought from the partner and, if granted, 
any pregnancy will be followed and the status of mother and/or child will be reported to 
the sponsor after delivery.  
A pregnancy notification form and follow-up will be completed. 
9.6 
Additional Study Restrictions 
The following additional restrictions will be in place for the duration of the study: 
1. Subjects must abstain from alcohol during the 24 h prior to screening and the 24 h 
prior to admission until discharge from the study 
2. Subjects must not drink liquids or eat food containing grapefruit, cranberry, caffeine 
or other xanthines from 24 h prior to admission until discharge from the study 
3. Subjects should refrain from eating food containing poppy seeds for 48 h prior to 
screening and for 48 h prior to admission until discharge from the study 
4. Subjects must not take part in any unaccustomed strenuous exercise from the 72 h 
before the screening visit and then from 72 h prior to admission until discharge from 
the study 
The additional restrictions above are not exclusion criteria; if non-compliance occurs, a 
protocol deviation will be completed.  
10 Study Procedures 
Study procedures will be performed as detailed in the study schedule of assessments 
in Appendix 2, and in accordance with Quotient Sciences standard operating 
procedures (SOPs) unless otherwise stated in this protocol. 
10.1 Screening 
Within the 28 days preceding first dose, all subjects will be required to undergo a 
screening visit. Screening procedures will be carried out in accordance with the study 
flow chart in Appendix 2. 
If the start of the study is delayed for any reason so that the interval between screening 
and first dose exceeds 28 days, all or part of the screening procedures may be 
repeated at the discretion of the investigator. 
Subjects previously screened generically may participate in this study provided they 
meet the subject selection criteria. Procedures required by this protocol will only be 
done if they were not performed during generic screening. All screening data must be 
obtained within 28 days prior to administration of study medication, as stipulated 
above. 
Screening safety procedures such as safety bloods, ECGs, vital signs, carbon 
monoxide breath tests, alcohol breath tests and urinalysis can be repeated as clinically 
indicated under the discretion of the investigator or sub-investigator if there is a 
concern regarding a subject’s safety or eligibility to participate in the trial.

10.1.1 Subject Re-Screening 
This study permits the re-screening of a subject who has discontinued the study as a 
pre-treatment failure (ie subject has not been treated); the reason for failure must be 
temporary and expected to resolve. If re-screened, the subject must be re-consented. 
10.2 Admission and Pre-dose Procedures 
The admission and pre-dose procedures are presented in Appendix 2.  
The identity of the subjects will be confirmed at admission and pre-dose.  
In 
addition, 
the 
ongoing 
eligibility 
of 
subjects 
will 
be 
re-assessed 
at 
admission/pre-dose, as described in Sections 9.2 and 9.3.  
Admission safety procedures such as safety bloods, ECGs, vital signs, urinalysis and 
drugs of abuse tests can be repeated as clinically indicated under the discretion of 
investigator or sub-investigator if there is a concern regarding a subject’s safety or 
eligibility to participate in the clinical trial. 
The subjects will be admitted to the clinical unit on the evening before dosing (Day -1).  
10.3 Study Day Procedures 
10.3.1 Blood Volume 
The total blood volume for each subject will not exceed 550 mL in a 4 week period.  
The first 0.5 mL of blood withdrawn via cannula will be discarded. 
10.3.2 Timing of Procedures 
There are times where the protocol requires more than one procedure to be completed 
at the same time point. In these instances the following will apply to post-dose time 
points: 
PK samples should take priority over other procedures scheduled at the same time 
point.  
As guidance, the preferred order of assessments is: 
ECGs 
 
Vitals 
 
PK blood 
sampling 
 
Other assessments 
eg physical 
examinations 
ECGs should be taken prior to vital signs when both measurements are scheduled at 
the same time point. Other assessments, eg physical examinations, will be performed 
within the required time windows. 
All safety assessments will be timed and performed relative to the start of dosing.

10.3.3 Discharge from the Clinical Unit 
A subject will be allowed to leave the premises without additional investigator or 
delegate review, following completion of study-specific procedures at discharge, 
providing that: 
 
no AEs have been reported during the study visit  
 
the subject responds in the affirmative when asked if they are feeling well 
Subjects will be dosed on the morning of Day 1 following an overnight fast and will 
remain resident in the clinical unit until up to 168 h after dosing (Day 8). It is planned 
that subjects will be released as a group when all subjects have achieved a mass 
balance cumulative recovery of >90% or if <1% of the dose administered has been 
collected in urine and faeces within 2 separate, consecutive 24 h periods. This may 
result in the subjects being discharged as a group prior to completion of the planned 
residency period. Once the discharge criteria or the planned residency period has been 
achieved, subjects will undergo discharge assessments and collection of all samples 
(blood, urine and faeces) will be stopped. If mass balance criteria have not been met 
by all subjects on Day 8, the residency period for the subjects not achieving the release 
criteria may be extended up to a maximum of 48 h post-dose (Day 10) for further 
collection of urine and/or faeces. If the criterion is still not met by Day 10, or if additional 
residency is not considered appropriate or necessary, then home collections of urine 
and/or faeces may be requested at the discretion of the investigator for individual 
subjects. 
If any of these conditions are not met, then the subject will only be allowed to leave the 
clinical unit with the authorisation of the investigator or appropriately qualified delegate. 
There will be no continued provision of the study intervention or treatment for subjects 
as this study involves healthy volunteers only. 
10.3.4 Medical Supervision 
A physician will be responsible for the clinical aspects of the study and will be available 
at all times during the study. In accordance with the current Association of the British 
Pharmaceutical Industry guidelines [13], each subject will receive a card stating the 
telephone number of the investigator and the 24/7 contact details of the Quotient 
on-call physician. 
11 Dosing of Subjects 
11.1 Food and Fluid Intake 
The calorie/fat content of meals is not required to be controlled during this study, with 
the exception of meals on Day 1. Meals on subsequent days will be provided at 
nominal times. 
Subjects will be allowed water up to 1 h before the scheduled dosing time and will be 
provided with 240 mL of water at 1 h post-dose. Water will be allowed ad libitum after 
1 h post-dose. Decaffeinated fluids will be allowed ad libitum from lunch time on the 
day of dosing.  
If, for technical reasons, dosing is delayed for more than 2 h beyond the expected 
dosing time, subjects will receive 200 mL of Lucozade Sport at the originally scheduled 
dosing time, or earlier if possible.

Page 34 of 54  
 
Subjects will be provided with a light snack and then fast from all food and drink 
(except water) for a minimum of 8 h the day prior to dosing until approximately 4 h 
post-dose, at which time lunch will be provided. An evening meal will be provided at 
approximately 10 h post-dose and an evening snack at approximately 14 h post-dose. 
On subsequent days, meals will be provided at appropriate times. 
If an individual subject has not experienced a bowel movement in any 36-h period 
post-dose, fluid intake should be increased and administration of a mild laxative 
(eg prune juice or a mild stool softener) should be implemented. 
11.2 Administration of Test Preparations 
Specific details of IMP(s) and doses to be administered are provided in Section 5.2 and 
Section 8.1, respectively. Subjects will be dosed on the morning of Day 1.  
The exact time of dosing will be decided based on logistics and will be documented in 
the source.  
Each subject will receive a single oral administration of a capsule containing 100 mg 
[14C]-MD1003 and NMT 2.22 MBq (60.0 µCi) on a single occasion in the fasted state. 
11.3 Dosing Compliance 
During all clinical phases of the study, subjects will be observed by study staff to 
assure compliance to all study procedures, including dose administration.  
Mouth and hand checks will be conducted after dosing to ensure the capsule has been 
swallowed.  
The date and time that each subject is dosed will be recorded in the subject’s source 
data. Any violation of compliance will require evaluation by the investigator and 
sponsor to determine if the subject can continue in the study. 
11.4 Prior and Concomitant Medications 
No prescribed, over-the-counter medication, herbal remedies, vitamin B5 or dietary 
supplements containing lipoic acid will be permitted from 14 days before IMP 
administration until discharge from the study except 4 g per day of paracetamol and 
those deemed necessary by the investigator to treat AEs (see also Section 9.3). Any 
medications used will be recorded in the source. 
Emergency equipment and drugs will be available within the clinical unit as per current 
standard procedures. In the unlikely event that they are required, their use will be 
documented.

13.1.1 Blood Sampling 
Venous blood samples will be collected from the subjects by a trained member of the 
clinical team. Consent will be collected from the subjects for use of these samples for 
the purposes of the proposed study.  
Plasma and whole blood samples are sent for laboratory testing in linked anonymised 
form (subject number only). This information is able to be linked directly to the 
volunteer by the Quotient research team and study monitor, however not by the 
laboratory staff or Sponsor. 
Venous blood samples will be withdrawn via an indwelling cannula or by venepuncture 
according to the time schedule presented in Appendix 2. 
The acceptable deviations from the nominal blood sampling times are as follows: 
 
The pre-dose samples will be taken ≤1 h before dosing 
 
0 to 1 h post-dose samples will be taken within ± 2 min of the nominal post-dose 
sampling time  
 
>1 to 12 h post-dose samples will be taken within ± 10 min of the nominal 
post-dose sampling time 
 
>12 h post-dose samples will be taken within ± 30 min of the nominal post-dose 
sampling time  
Samples will be collected into appropriate tubes as specified by the bioanalytical 
laboratory. Details of sample tubes and processing will be contained in the 
Clinical Sample Processing Manual. 
Samples will be shipped to Pharmaron for the analysis of total radioactivity in plasma 
and whole blood, and for metabolite profiling and identification in plasma. Samples will

13.2 Assessment of Pharmacodynamics 
Not applicable for this Phase I study. 
14 Assessment of Safety 
14.1 Definition and Classification of Adverse Events 
An AE is any untoward medical occurrence in a subject that occurs either before 
dosing (referred to as a pre-dose AE) or once a medicinal product has been 
administered, including occurrences which are not necessarily caused by or related to 
that product.  
An adverse drug reaction is any AE where a causal relationship with the IMP is at least 
a reasonable possibility (possibly related or related). 
AEs will be monitored from the time the subject signs the ICF until discharge from the 
study. The severity of AEs should be assessed as follows: 
Mild 
An AE that is easily tolerated by the subject, causes minimal discomfort 
and does not interfere with everyday activities 
Moderate An AE that is sufficiently discomforting to interfere with normal everyday 
activities; intervention may be needed 
Severe 
An AE that prevents normal everyday activities; treatment or other 
intervention usually needed

14.2 Assessment of Causality 
Every effort should be made by the investigator to try to explain each AE and assess its 
relationship, if any, to the IMP. The temporal relationship of the event to IMP 
administration should be considered in the causality assessment (ie if the event starts 
soon after IMP administration and resolves when the IMP is stopped). 
Causality should be assessed using the following categories:  
Unrelated: 
Clinical event with an incompatible time relationship to IMP 
administration, and that could be explained by underlying 
disease or other drugs or chemicals or is incontrovertibly not 
related to the IMP 
Possibly related: 
Clinical event with a reasonable time relationship to IMP 
administration, and that is unlikely to be attributed to 
concurrent disease or other drugs or chemicals 
Related: 
Clinical event with plausible time relationship to IMP 
administration and that cannot be explained by concurrent 
disease or other drugs or chemicals 
The degree of certainty with which an AE is attributed to IMP administration (or 
alternative causes, eg natural history of the underlying disease, concomitant therapy) 
will be determined by how well the experience can be understood in terms of one or 
more of the following: 
 
known pharmacology of the IMP 
 
reactions of a similar nature have been previously observed with the IMP or this 
class of drug 
 
the experience being related by time to IMP administration, terminating with IMP 
withdrawal or recurring on re-challenge 
 
alternative cause 
14.3 Recording Adverse Events 
AEs will be recorded from the time of providing written informed consent until discharge 
from the study. During each study visit the subject will be questioned directly regarding 
the occurrence of any adverse medical event according to the schedule in the source. 
All AEs, whether ascribed to study procedures or not, will be documented immediately 
in the source. This will include the date and time of onset, a description of the AE, 
severity, duration, actions taken, outcome and an investigator’s current opinion on the 
relationship between the study drug and the event. A diagnosis and final opinion on the 
relationship between the study drug and the event will be provided at the end of the 
study by the investigator.  
Any subject who withdraws from the study due to an AE will be followed up until the 
outcome is determined and written reports provided by the investigator.

14.4 Serious Adverse Events 
14.4.1 Definition of Serious Adverse Events 
A serious adverse event (SAE) is defined as any untoward medical occurrence that at 
any dose:  
 
results in death 
 
is life-threatening 
 
requires hospitalisation or prolongation of existing hospitalisation 
 
results in persistent or significant disability or incapacity 
 
consists of a congenital anomaly or birth defect 
 
an important medical event as recognised by the PI 
SAEs must be immediately (without any delay) reported to the sponsor and in any case 
no later than 24 h of becoming aware of the event. 
14.4.2 Definition of Suspected Unexpected Serious Adverse Reactions 
Suspected unexpected serious adverse reactions (SUSARs) are AEs that are believed 
to be related to an IMP and are both unexpected (ie the nature or severity is not 
expected from the information provided in the Reference Safety Information (RSI) 
section of the Investigator’s Brochure Edition No 10) and serious. SUSARs are subject 
to expedited reporting to the MHRA, European Medicines Agency (EMA) and EC (see 
Section 16.3.2 for details on reporting SUSARs). 
14.5 Laboratory Measurements 
Venous blood, urine and faecal samples will be collected from the subjects by a trained 
member of the clinical team. Consent will be collected from the subjects for use of 
these samples for the purposes of the proposed study. 
Blood, urine and faecal samples are sent for laboratory testing in linked anonymised 
form (subject number, initials and the subjects’ gender and date of birth for analytical 
reasons). This information is able to be linked directly to the volunteer by the Quotient 
research team and study monitor, however not by the laboratory staff or sponsor. 
Safety laboratory tests and virology will be carried out on blood samples, and drugs of 
abuse tests and urinalysis will be carried out on urine samples. The research will not 
involve analysis or use of human DNA. 
Blood and urine samples results will be reviewed by a physician and acted upon before 
the subject is dosed or receives their next dose, or is released from the study, as is 
appropriate. A list of the laboratory parameters measured is presented in Appendix 1. 
14.5.1 Haematology and Clinical Chemistry 
Laboratory tests will be performed by The Doctors Laboratory according to the time 
schedule presented in Appendix 2. Blood samples will be collected and processed as 
detailed in the Clinical Sample Processing Manual. Scheduled blood samples will be 
taken following an 8 h fast. 
The acceptable deviations from the nominal blood sampling time points for laboratory 
assessments are:

 
The pre-dose blood sample will be taken ≤2 h before dosing 
 
Post-dose blood samples will be taken ± 1 h from the nominal blood sampling time  
Creatinine clearance (CLcr) will be calculated at screening by The Doctors Laboratory 
using the Cockcroft-Gault equation and body weight for eligibility purposes: 
CLcr (mL/min) = (140-age [years]) x (body weight [kg]) (× 1.23) 
 
serum creatinine (µmol/L) 
14.5.2 Urinalysis 
Urinalysis will be performed on-site using a dipstick according to the time schedule 
presented in Appendix 2. Urine samples will be collected and processed as detailed in 
the Clinical Sample Processing Manual. If microscopy is required, a urine sample will 
be sent to The Doctors Laboratory. Any urine used for urinalysis will be added back to 
the full sample for total radioactivity analysis. If microscopy is required, a urine sample 
(approximately 20 mL) will be taken from the urine collection, and sent to The Doctors 
Laboratory after the void has been weighed. 
The acceptable deviations from the nominal urine sampling time points for urinalysis 
are: 
 
The pre-dose urine sample will be taken ≤3 h before dosing or the first void of the 
day 
 
Post-dose urine samples will be taken ± 2 h from the nominal urine sampling time 
14.5.3 Drug Screen 
A urine drug screen will be performed on-site using a dipstick method according to the 
time schedule presented in Appendix 2. The sample will be collected and processed as 
detailed in the Clinical Sample Processing Manual. Subjects will be screened for the 
drugs of abuse listed in Appendix 1.  
14.5.4 Alcohol Breath Test 
An alcohol breath test will be performed according to the time schedule presented in 
Appendix 2. A positive result will exclude the subject from dosing during that 
admission. 
14.5.5 Carbon Monoxide Breath Test 
A carbon monoxide breath test will be performed according to the time schedule 
presented in Appendix 2. A result of greater than 10 ppm will exclude the subject from 
the study. 
14.5.6 Abnormal Laboratory Findings 
In cases where laboratory findings are outside the normal range and the investigator 
believes that the results may be of clinical significance, repeat sampling may be 
requested as clinically indicated. If the abnormal finding is clinically significant, 
appropriate actions will be taken eg the subject will not be entered into the study or the 
subject may be withdrawn from the study. The subject will be referred to their GP or 
other appropriate provider for further care. The same will apply if the results of the 
HBsAg, HCV Ab or HIV test are positive and in addition the investigator will ensure that 
adequate counselling is available if requested.

Abnormal results at follow-up assessments will also require repeat testing if the 
investigator believes the results may be of clinical significance. 
Any clinically significant abnormality, including changes from baseline, must be 
reported as an AE. 
Additional blood and/or urine samples may be taken for safety tests. Furthermore, 
additional assays outside those specified in the protocol may be performed for safety 
reasons as requested by the investigator or sub-investigator. 
14.6 Vital Signs Measurements 
Blood pressure and heart rate will be measured by an automated recorder after the 
subject has been in a supine position for a minimum of 5 min according to the time 
schedule presented in Appendix 2. Oral temperature will also be measured. The 
acceptable deviations from the nominal vital signs measurement time points are: 
 
The pre-dose vital signs measurements will be taken ≤2 h before dosing. 
 
Post-dose vital signs measurements will be taken ± 15 min from the nominal 
post-dose time points. 
 
Discharge vital signs measurements will be taken ± 1 h from the nominal time point. 
If a subject shows an abnormal assessment at any stage, repeat measurements may 
be made and the abnormality followed to resolution if required. Additional 
measurements may be taken as deemed necessary by the investigator or sub-
investigator. 
Any clinically significant abnormality, including changes from baseline, must be 
reported as an AE. 
14.7 ECG Measurements 
Single 12-lead ECGs will be measured after the subject has been in the supine position 
for a minimum of 5 min according to the time schedule presented in Appendix 2. The 
acceptable deviations from the nominal ECG measurement time points are: 
 
The pre-dose ECG measurements will be taken ≤2 h before dosing 
 
Post-dose ECG measurements will be taken ± 15 min from the nominal post-dose 
time point. 
 
Discharge ECG measurements will be taken ± 1 h from the nominal time point.  
If a subject shows an abnormal assessment at any stage, repeat measurements may 
be made and the abnormality followed to resolution if required. Additional 
measurements may be taken as deemed necessary by the investigator or sub-
investigator. 
Any clinically significant abnormality, including changes from baseline, will be reported 
as an AE.

14.9 Physical Examination 
Subjects will undergo a physical examination as detailed in Appendix 2. 
14.10 Additional Safety Procedures 
Additional non-invasive procedures that are already specified in the protocol may be 
performed, if it is believed that an important effect of the IMP(s) is occurring or may 
occur at a time when no measurements are scheduled, or if extra procedures are 
needed in the interests of safety. 
Additional blood samples for safety assessments may be taken if required by the 
investigator at any point. 
15 Statistics and Data Analysis 
15.1 Sample Size Justification 
The study is exploratory and no formal sample size calculation has been made. Based 
on experience from previous studies of a similar design, a total of 6 subjects is to be 
enrolled and a minimum of 4 evaluable subjects is considered sufficient. 
15.2 Data Management 
Data management will be performed by Quotient Sciences. 
Study data will be managed using a validated electronic case report form (eCRF) 
database system and subjected to data consistency and validation checks. Data 
queries will be raised within the study eCRF database by data management staff and 
resolved with the assistance of clinical staff. 
AEs and medications will be coded using the Medical Dictionary for Regulatory 
Activities (MedDRA) (v22.0 or a more recent version) and the World Health 
Organisation (WHO) Drug Dictionary Global Drug Reference (2019 or a more recent 
version), respectively. An independent coding review will also be performed within the 
Data Sciences department. 
Clinical chemistry and haematology data (and other safety laboratory data) will be 
collected by a central laboratory (The Doctors Laboratory) and stored electronically in 
their clinical pathology system. The data will be transferred electronically to Quotient 
Sciences and all demographic details and sample dates will be cross-referenced with 
the corresponding data on the study database. All queries will be resolved with the 
assistance of laboratory staff, or if necessary, clinical staff.  
The database will be closed after all queries have been resolved. The database will be 
locked when all criteria listed in the Data Management Plan (DMP) are met.  
Further details are addressed in the DMP. 
15.3 Mass Balance Data Analysis 
Urine and faeces will be collected for the analysis of total radioactivity. Graphical and 
tabular representation of whole blood and plasma total radioactivity concentrations and 
ratios at selected time points will be presented. The following mass balance 
parameters will be calculated by Quotient Sciences for urine, faeces and combined 
urine and faeces (ie total radioactivity from all excreta).

16 Safety Reporting to Ethics Committees and Regulatory 
Authorities 
16.1 Events Requiring Expedited Reporting 
SUSARs (Section 14.4.2) are subject to expedited reporting to the MHRA, EMA and 
EC. 
In addition to SUSARs, other safety issues may qualify for expedited reporting where 
they might materially alter the current benefit-risk assessment of an IMP or that would 
be sufficient to consider changes in the IMPs administration or in the overall conduct of 
the study, for instance: 
 
an increase in the rate of occurrence or a qualitative change of an expected serious 
adverse reaction, which is judged to be clinically important 
 
SAEs that occur after the subject has completed the clinical study where the 
sponsor considers them to be a SUSAR 
 
new events related to the conduct of the study or the development of the IMPs and 
likely to affect the safety of the subjects, such as: 
− an SAE which could be associated with the study procedures and which 
could modify the conduct of the study 
− a major safety finding from a newly completed animal study (such as 
carcinogenicity) 
− any anticipated end or temporary halt of a study for safety reasons and 
conducted with the same IMPs in another country by the same sponsor 
16.2 Urgent Safety Measures 
If Quotient Sciences or any of its staff or contractors becomes aware of an actual or 
potential urgent safety issue, then the sponsor must be immediately contacted so that 
appropriate urgent safety measures can be agreed. An urgent safety issue is defined 
as:  
 
An immediate hazard to the health or safety of subjects participating in a clinical 
study 
 
A serious risk to human health or potentially a serious risk to human health 
An urgent safety issue may include issues with an investigational drug or comparators, 
study procedures, inter-current illness (including pandemic infections), concomitant 
medications, concurrent medical conditions or any other issues related to the safe 
conduct of the study or that pose a risk to study subjects. 
In exceptional circumstances of imminent hazard and in order to safeguard the health 
or safety of individuals, Quotient Sciences may take urgent safety measures before 
informing the sponsor, but the sponsor must be informed immediately after the hazard 
has resolved.  
Quotient Sciences will take responsibility for informing appropriate competent 
authorities, and the EC.

The investigator is required to notify the study sponsor if appropriate immediately and 
not later than 24 h of becoming aware of the occurrence of an SAE or serious adverse 
reaction. A copy of the written report of the event should promptly be sent to the study 
sponsor for information purposes, in accordance with International Council for 
Harmonisation (ICH) guidelines for GCP. 
16.3.2 Reporting 
of 
Suspected 
Unexpected 
Serious 
Adverse 
Reactions 
(SUSARs) 
It is the responsibility of the sponsor to determine whether a reported SAE fits the 
classification of a SUSAR and to notify the investigator of their decision as soon as 
possible. 
16.3.3 Expedited Reporting of Events 
It is the responsibility of the sponsor to determine whether an event requires expedited 
reporting and to notify the investigator of their decision as soon as possible. 
Where expedited reporting is required, the following procedures should be followed. 
Fatal or life-threatening SUSARs 
It is the responsibility of the sponsor to report fatal or life-threatening SUSARs to the 
MHRA and EMA as soon as possible, but no later than 7 calendar days after they first 
became aware of the reaction. Any additional relevant information should be sent 
within 8 days of the report. This responsibility may be delegated to the 
pharmacovigilance provider.  
The investigator is required to notify the EC of any SUSAR as soon as possible, but no 
later than 7 calendar days after they first became aware of the reaction. Any additional 
relevant information should be sent within 8 days of the report.  
The ARSAC Practitioner will be notified of any SUSAR that is considered related to the 
exposure to radioactivity. 
Other SUSARs 
It is the responsibility of the sponsor to report other SUSARs to the MHRA and EMA as 
soon as possible, but no later than 15 calendar days after they first became aware of 
the reaction. This responsibility may be delegated to the pharmacovigilance provider. 
The investigator is required to notify the EC of other SUSARs as soon as possible, but 
no later than 15 calendar days after they first became aware of the reaction.  
The ARSAC Practitioner will be notified of any SUSAR that is considered related to the 
exposure to radioactivity 
16.3.4 Reporting of Urgent Safety Issues

16.4 Serious Breaches 
It is the responsibility of the sponsor to notify the licensing authority of any serious 
breach, which is likely to affect, to a significant degree, the safety or mental integrity of 
the subjects of the study or the scientific value of the study.  
All serious breaches will be notified to the MHRA within 7 days. The reporting will be 
performed by the party who suspects the serious breach. 
17 Protocol Amendments and Deviations 
17.1 Amendments 
After the protocol has been submitted to the MHRA and/or EC, any amendment must 
be agreed by the investigator after discussion with the sponsor and will be formally 
documented. 
All substantial amendments will be submitted to the MHRA and/or EC for an opinion as 
required by current regulations. Any amendments relating to the administration of 
radioactive substances will be reviewed by the ARSAC practitioner prior to submission 
to ARSAC as required by the current ARSAC Notes for Guidance. The ARSAC 
practitioner will also be notified of any substantial amendments to the PIS and ICF 
and/or protocol. 
If the PIS and ICF are updated as a result of the substantial amendment, the new 
approved versions will be used to re-consent currently enrolled subjects and must be 
provided to additional/replacement subjects prior to their entry into the study. 
17.2 Protocol Deviations 
The study must be conducted in accordance with the Clinical Protocol. Should a 
protocol deviation occur, it must be promptly assessed in order to decide whether any 
of these non-compliances should be reported to the MHRA as a serious breach of GCP 
and the Clinical Protocol. 
Protocol waivers are not acceptable. 
Deviations from the protocol will be recorded in the source as noted by the clinical staff. 
If necessary, the sponsor will be informed of the deviation. 
Any protocol deviations assessed as major will be discussed with the sponsor in order 
to determine if the withdrawal criteria stated in Section 8.3 have been met.

18.4 Administration of Radiation 
Dr Stuart Mair will be the ARSAC practitioner for this study, which includes the 
administration of radiation at Quotient Sciences. Administration will be conducted in 
accordance with Dr Mair’s current ARSAC practitioner licence and Quotient’s current 
ARSAC Employer licence. Additionally a research application will be submitted to 
ARSAC to obtain approval for the conduct of the study before dosing. 
Before submitting to the ARSAC, a summary of available nonclinical tissue distribution 
and excretion information on [14C]-MD1003 will be submitted to the Radiation 
Protection Division of PHE for human dosimetry calculations in order to facilitate the 
selection of the dose of radioactivity to be administered. The final report from the PHE 
will be included in the application to the ARSAC. 
The protocol will be reviewed and the final version will be approved by the ARSAC 
practitioner, Dr Stuart Mair. 
18.5 Source Data 
A study-specific source document identification list will be finalised with the sponsor 
prior to the start of the clinical phase of the study. The document will identify what data 
should be considered source data for this study.  
For this study, electronic data capture will be used where possible and data will be 
automatically recorded into an eCRF. In instances where paper source documents are 
used, data to be transcribed into the eCRF will be identified using a Source Document 
Identification List, as governed by Quotient Sciences SOPs.

The personal data of volunteers will be pseudonymised in that they will only include 
health, initials, date of birth and demographics (gender and ethnicity) and cannot be 
linked back to the individual by the recipient. The sponsor shall be the data controller in 
respect of the personal data of the study subjects collected in connection with the 
study, and shall act in accordance with the relevant data protection laws in relation to 
the collection and processing of those personal data. The study subjects’ 
pseudonymised personal data shall be collected and processed for the purposes of the 
study and may also be added to research databases and used in the future by the 
sponsor and its affiliates for certain additional clinical research, for product regulation 
and safety reporting purposes and for ensuring compliance with legal requirements. 
The study subjects’ pseudonymised personal data may be processed for such 
purposes by other parties including: the sponsor’s affiliates and licensing partners, its 
business partners, regulatory agencies and other health authorities, and ECs. The 
study subjects’ authorisation for such use and disclosure shall be obtained by the study 
subjects signing the ICF for the study. 
Additionally, Quotient personnel are contractually bound by a duty of confidentiality and 
receive training in this matter. 
18.9 Data Security Breach 
Quotient has a comprehensive process in place for identifying, assessing, resolving 
and reporting any potential data security breach. All staff are trained in the identification 
of potential data security breaches. Potential breaches are managed by appropriately 
trained quality assurance personnel in accordance with Quotient Sciences standard 
operating procedures. After robust assessment of data breaches, those deemed 
serious will be reported to the sponsor and Information Commissioner’s Office, as 
applicable.

a Discharge from clinical unit; subjects may be discharged earlier if a cumulative mass balance recovery of 90% % has been achieved or if <1% of the dose 
administered has been collected in urine and faeces within 2 separate consecutive 24 h periods. If the criteria are not met by Day 8, this may result in the 
extension of the residency period for the subjects not achieving the release criteria up to a maximum of an additional 48 h (up to Day 10) for further collection of 
urine and/or faeces. If the criteria are still not met by Day 10, or if additional residency is not considered appropriate or necessary, then home collections of urine 
and/or faeces may be requested at the discretion of the investigator for individual subjects

Introduction 
This document details the following for Quotient Sciences (Quotient) Study QSC201639 
(MD1003CT2019-03MB): 
 
criteria to be used for the definition of the populations and analysis sets relating to 
safety, mass balance and pharmacokinetic (PK) data 
 
handling of missing data 
 
proposed tables, figures and listings (TFLs) for demographic, dosing, mass balance, 
PK and safety data  
 
methods for mass balance and PK parameter estimation 
 
This document has been compiled according to the Quotient standard operating 
procedure (SOP) “Production of Reporting and Analysis Plans” and has been written 
based on information contained in the final study protocol (version 1.0) dated 
12 Sep 2019. 
3.1 
Responsibilities 
The Data Sciences Department at Quotient will be responsible for the production of the 
following items using Quotient SOPs: Clinical Data Interchange Standards Consortium 
(CDISC) study data tabulation model (SDTM) and analysis data model (ADaM) datasets, 
mass balance parameter estimation and output, PK parameter estimation and output; 
including all TFLs; and the clinical study report (CSR). 
Quotient will provide two sets of TFLs during the study: 
 
post database lock TFLs (draft) for MedDay Pharmaceuticals review, and  
 
post-review TFLs (final) for inclusion into the CSR 
Quotient will be responsible for the quality control (QC) of all deliverables prior to the 
client review (Section 13.2). 
Metabolite profiling and structural identification will be the responsibility of Pharmaron, 
and will be the subject of a separate Analytical Work Plan. These aspects will be reported 
separately from the CSR as a standalone document. 
3.2 
Definitions 
3.2.1 
Subject Definitions 
During the clinical phase of the study, an evaluable subject is defined as a subject who 
has provided mass balance and PK samples for up to 72 h (Day 4) after IP administration, 
or have demonstrated >90% mass balance recovery, or have <1% of the administered 
dose eliminated in excreta for 2 consecutive days, whichever is sooner. This will be 
monitored during the clinical phase but will not be used during the reporting phase 
including the identification of analysis populations and datasets. 
An enrolled subject is defined a subject who signed the informed consent, qualified per 
the inclusion/exclusion criteria and were allocated a subject number.

5 
Study Design 
5.1 
Brief Description 
This is a single-centre, open-label, non-randomised, single oral dose study in healthy 
male subjects. It is planned to enrol 6 subjects. 
The study design is presented in Figure 1. Subjects will be screened to participate in the 
study up to 28 days before dosing. Subjects will be admitted to the clinical unit on the 
evening of Day -1 prior to IP administration. 
Subjects will be dosed in the morning of Day 1 following an overnight fast with a single 
oral administration of a capsule containing 100 mg MD1003 and NMT 2.22 MBq 
(approximately 60.0 µCi) [14C]-MD1003. 
Subjects will remain resident in the clinical unit until up to 168 h after dosing (up to Day 8). 
It is planned that subjects will be released as a group when all subject have achieved a 
mass balance cumulative recovery of >90% or if <1% of the dose administered has been 
collected in urine and faeces within 2 separate consecutive 24 h periods. This may result 
in the subjects being discharged as a group prior to completion of planned residency 
period. Once the discharge criteria or the planned residency period has been achieved, 
collection of all samples (blood, urine and faeces) will be stopped and subjects will 
undergo discharge assessments. If the mass balance criteria have not been met by all 
subjects by Day 8, the residency period for the subjects not achieving the release criteria 
may be extended up to a maximum of an additional 48 h (up to Day 10) for further 
collection of urine and/or faeces. If the residency is not considered appropriate or 
necessary, then home collections of urine and/or faeces may be requested at the 
discretion of the investigator for individual subjects.

a Subject may be discharged as a group earlier if a cumulative recovery of >90% has been achieved or if 
<1% of the dose administered has been collected in urine and faeces within 2 separate consecutive 24 h 
periods. If the criteria are not met by Day 8, this may result in the extension of the residency period for the 
subjects not achieving the release criteria up to a maximum of an additional 48 h (up to Day 10) for further 
collection of urine and/or faeces. If the criteria are still not met by Day 10, or if additional residency is not 
considered appropriate or necessary, then home collections of urine and/or faeces may be requested at the 
discretion of the investigator for individual subjects.  
5.2 
Criteria for In-Study Decisions 
Not applicable for this study. 
5.3 
Study Sample Size 
This study is exploratory and no formal sample size calculation has been made. Based 
on experience from previous studies of a similar design, a total of 6 subjects is to be 
enrolled and a minimum of 4 evaluable subjects is considered sufficient. 
5.4 
Subject Numbers 
This is an open-label, non-randomised study, therefore a randomisation schedule will not 
be produced.  
Subject numbers will be allocated on the morning of dosing according to the code 001 to 
006 using the lowest number available. 
No replacement subjects are to be used in this study. 
5.5 
Blinding Issues 
This is an open-label, non-randomised study and, therefore, blinding is not required. 
6 
Populations and Analysis Sets 
6.1 
Safety Population and Safety Analysis Set 
The safety population will include all subjects who have received any amount of IP. 
The safety analysis set will include all relevant data from the subjects included in the 
safety population.

The safety population will be confirmed by Quotient with approval from MedDay 
Pharmaceuticals after database lock and will be used for the populations table and to 
determine the subjects to be included in the safety analysis set. 
The safety analysis set will be confirmed by Quotient with approval from MedDay 
Pharmaceuticals at the same time as the safety population and will be used for the 
analysis of demographic and baseline characteristics, and all safety data. 
6.2 
Mass Balance Population and Mass Balance Analysis Set 
The mass balance population will include all subjects who have received IP, who have 
evaluable total radioactivity concentration (urinary and faecal) data and who have no 
protocol deviations that affect the mass balance analysis. Such protocol deviations would 
include anything that affects the accurate measurement of amount of urine/faeces 
collected or any AEs that may affect the mass balance analysis, for example: 
 
spillage of urine and/or faeces 
 
missing collections 
 
AEs that may affect the mass balance analysis, such as vomiting of the dose 
The mass balance analysis set will include all relevant data from the subjects included 
in the mass balance population.  
The mass balance population will be confirmed by Quotient with approval from MedDay 
Pharmaceuticals once all urinary and faecal data have been received and will be used 
for the populations table and to determine the subjects to be included in the mass 
balance analysis set. 
The mass balance analysis set will be confirmed by Quotient with approval from MedDay 
Pharmaceuticals at the same time as the mass balance population and will be used for 
the provision of mass balance summary tables and figures.  
6.3 
Pharmacokinetic Population and Pharmacokinetic Analysis Set 
The PK population will include all subjects who have received IP and who satisfy the 
following criteria for at least 1 profile: 
 
no missing samples or invalid post-dose analytical results at critical time points eg 
around the Tmax 
 
no relevant protocol deviations which may impact the study objectives with respect 
to the PK endpoints 
 
no relevant AEs such as vomiting after dosing which suggest that the whole dose 
was not available for absorption for a particular subject 
The PK analysis set will include all relevant data from the subjects included in the PK 
population. 
The PK population will be confirmed by Quotient with approval from MedDay 
Pharmaceuticals following derivation of all PK parameter estimates and will be used for 
the populations table and to determine the subjects to be included in the PK analysis set.

Subject 
Disposition, 
Demographics 
and 
Baseline 
Characteristics 
No formal statistical testing will be performed on subject disposition, or on demographic 
or baseline data. Summaries of subject disposition and analysis populations will be 
based on all enrolled subjects and summaries of all other data described in this section 
will be based on the safety analysis set, unless otherwise stated. 
7.1 
Screening Failures 
Data for subjects who have failed screening will be databased but will not be cleaned 
and therefore will not be included in the SAS extracts, SDTM or ADaM datasets or any 
of the TFLs. 
7.2 
Subject Disposition and Withdrawals 
The number and percentage of subjects enrolled, dosed, completed and discontinued 
will be presented. If any subjects discontinued from the study early then the number of 
subjects for each reason for discontinuation will be presented. However, if none of the 
subjects discontinued from the study early, then the reasons for discontinuation will not 
be populated in the summary table. 
Subject disposition and withdrawal data will be listed including details of informed 
consent. 
Protocol deviations and any violations of the inclusion/exclusion criteria will also be listed. 
7.3 
Analysis Populations 
A summary table will be produced detailing the number and percentage of subjects in 
each safety, mass balance and PK population. The reasons for exclusion from each 
population will also be included in the summary.  
Details of subjects included in and excluded from the different analysis populations will 
be listed. 
7.4 
Analysis Sets 
A summary table will be produced detailing the number and percentage of subjects in 
each safety/mass balance/PK analysis set. The table will be based on the relevant 
population the analysis set is a subset of (ie the safety/mass balance/PK population). 
The reasons for exclusion from each analysis set will also be included in the summary.  
Details of subjects included and excluded in the different analysis sets will be listed.

7.5 
Demographic Characteristics and Lifestyle Details 
Demographic data (date of birth, ethnicity, race, sex, height [cm], weight [kg] and body 
mass index [BMI; kg/m2]) will be recorded at screening. Age will be calculated using the 
following formula: 
Age (years) = 
Date of Informed Consent – Date of Birth 
365.25 
and will be rounded down to the nearest year (using the SAS Software floor function). 
Summary statistics (ie number of subjects with an observation [n], mean, standard 
deviation [SD], median, minimum and maximum) will be presented for age, height, weight 
and BMI at screening. The number and percentage of subjects will be presented for 
ethnicity, race and sex. The denominator for the percentage is all subjects in the safety 
analysis set. If any values are missing, a “missing” row will be presented on the table. 
Lifestyle details (ie smoking history [does the subject smoke, use e-cigarettes or any 
nicotine replacement products?] and alcohol consumption) will be summarised as 
categorical variables. 
Demographic and lifestyle data will be listed by subject for all enrolled subjects. 
7.6 
Medical/Surgical History 
Medical/surgical history will be recorded for each subject at the screening visit and 
updated at admission. All medical/surgical history data will be listed by subject for all 
enrolled subjects. 
7.7 
Prior and Concomitant Medication 
Medications (product name) will be coded using the World Health Organization (WHO) 
Drug Dictionary Global Drug Reference (2019 September version or more recent 
version) using the following Anatomical Therapeutic Chemical (ATC) classification 
codes: 
 
product name 
 
preferred name  
 
drug code 
 
therapeutic subgroup (ATC 2nd level code) 
 
chemical subgroup (ATC 4th level code) 
Prior medications are defined as medications that start and stop prior to the dosing of IP. 
All other medications will be defined as concomitant medications including those that 
start prior to the first dose of IP and continue thereafter. Any medications with an 
unknown start or stop date will be assumed to be concomitant medications unless a 
partial start or stop date indicates otherwise.

7.7.1 
Summary Table for Prior and Concomitant Medication 
If 2 or more subjects receive concomitant medications, a table will be presented to 
summarise concomitant medications data.  
All subjects taking concomitant medications will be summarised. Counts will be given for 
total number (and percentage) of subjects who received concomitant medications and 
total number of occasions in which medications were taken. 
Additionally, concomitant medication will be summarised by therapeutic subgroup, 
chemical subgroup and preferred name. Counts will be given for the number (and 
percentage) of subjects and total number of occasions in which medications were taken. 
No summary table will be presented for prior medication. 
7.7.2 
Listing for Prior and Concomitant Medication 
All medications, including coded terms and the underlying indication for which the 
medication was given, will be listed. One combined data listing of prior and concomitant 
medications will be provided. All prior medications as defined above will be flagged with 
a “#” symbol. Within this flagged group, medications that started after screening and 
stopped before dosing of IP will also be flagged using a “*” symbol. 
7.8 
Other Baseline Characteristics 
All other baseline characteristics, as listed below, at screening and on admission (unless 
otherwise stated) will be listed by subject for all enrolled subjects: 
 
carbon monoxide breath test 
 
urine drug screen 
 
alcohol breath test  


Mass Balance and Pharmacokinetics 
9.1 
Mass Balance Parameter Estimation and Reporting  
Pharmaron will provide the following concentration and weight data on a per subject 
basis for each collection period as specified in the clinical protocol: 
 
amount of dose received (mg) and radioactive dose received (µCi and MBq) 
 
total radioactivity concentration (mass unit equivalents/g) 
 
weight of urine (g)  
 
faeces weight (g) ie not faecal homogenate weight

Concentration values will be expressed in terms of mass unit equivalents of the free base 
form. Quotient Data Sciences will be responsible for the calculation of excretion and 
recovery of total radioactivity in urine, faeces and urine and faeces combined for 
inclusion into the CSR.  
For the purposes of this document, “excretion” will be used when describing the amount 
of total radioactivity excreted and “recovery” will be used when describing the amount of 
total radioactivity expressed as a percentage of the radioactive dose administered.

Home collections of urine and/or faeces may be requested at the discretion of the 
investigator for individual subjects. All mass balance parameters will be calculated for all 
collection periods including home collections, if applicable. 
9.1.2 
Rules for Mass Balance Parameter Estimation  
The following will be calculated for total radioactivity in urine, faeces and total (ie urine 
and faeces combined) by Quotient Data Sciences (note that the amount excreted in pre-
dose samples will not be included in the calculation of the cumulative amount excreted 
or in the calculation of the cumulative percentage of the radioactive dose excreted): 
 
The amount excreted in urine, ie Ae(urine), and the amount excreted in faeces, ie 
Ae(faeces), will be calculated for each collection period using the following formula 
(where matrix is either urine or faeces): 
Ae(<matrix>) = concentration * weight 
 
 
The total amount excreted in urine and faeces combined, ie Ae(total), will be 
calculated for each collection period using the following formula: 
Ae(total) = Ae(urine) + Ae (faeces) 
 
 
The cumulative amount excreted in urine, ie CumAe(urine), and the cumulative 
amount excreted in faeces, ie CumAe(faeces), will be calculated by the incremental 
summation of the Ae(<matrix>) across all collection periods (where matrix is either 
urine or faeces).  
 
The cumulative amount excreted in urine and faeces combined, ie CumAe(total), will 
be calculated across all collection periods using the following formula: 
CumAe(total) = CumAe(urine) + CumAe(faeces) 
 
The % amount of the total radioactive dose excreted in urine, ie %Ae(urine), and 
the % amount of the total radioactive dose excreted in faeces, ie %Ae(faeces), will 
be calculated for each collection period using the following formula (where matrix is 
either urine or faeces): 
%Ae(<matrix>) = 100 * Ae(<matrix>) / Total Radioactive Dose Administered

 
The % amount of the total radioactive dose excreted in urine and faeces combined, 
ie %Ae(total), will be calculated for each collection period using the following 
formula: 
%Ae(total) = %Ae(urine) + %Ae(faeces) 
 
The cumulative % amount of the total radioactive dose excreted in urine, ie 
Cum%Ae(urine), and the cumulative % amount of the total radioactive dose 
excreted in faeces, ie Cum%Ae(faeces), will be calculated by the incremental 
summation of the %Ae(<matrix>) across all collection periods (where matrix is 
either urine or faeces). 
 
The cumulative % amount of the total radioactive dose excreted in urine and faeces 
combined, ie Cum%Ae(total), will be calculated for each collection period using the 
following formula: 
Cum%Ae(total) = Cum%Ae(urine) + Cum%Ae(faeces) 
Where the collection periods for urine and faeces differ (ie, on Day 1 urine collected at 
12 h intervals while faeces collected over 24 h), the total excretion and recovery (ie, urine 
and faeces combined) will be calculated over the larger of the intervals. 
For urine and faeces, where a subject has failed to void over a particular collection period 
the Amount excreted (Ae) will be set to zero. 
If part of a void over a particular collection period is missing due to spillage or accidental 
discarding, the Ae will still be calculated providing other samples have be collected within 
the interval. Where no other samples are collected within the interval the data will be set 
to missing for the purposes of the calculation of Ae, %Ae, CumAe and Cum%Ae. In both 
scenarios the data will be flagged to highlight a missing void. 
Non-numerical values reported in the urine and faecal data set (ie concentrations that 
are ND) will be entered as zero for calculation of mass balance parameters. 
When converting urine collection weights to urine volume (if required), the following 
conversion factor will be used: 
1.02 g of urine = 1 mL of urine 
This will be calculated in SAS as follows: 
Urine weight (g) / 1.02 = Urine volume (mL) 
If total radioactivity concentrations in urine have been provided in mass unit/g units the 
following conversion (if required) will be performed using SAS: 
Concentration (mass units/g) * 1.02 = Concentration (mass units/mL)

The radioactivity associated with toilet paper may be determined at the request of the 
sponsor. The results will be reported for each subject as a single value for the whole 
collection period and included in the calculation of amount excreted and % of dose 
recovered. 
Other unexpected sources of elimination will be collected as voided (ie, emesis) and 
samples will be shipped to Pharmaron for the analysis of total radioactivity. Such cases 
will be discussed with Med Day and details regarding the reporting will be documented. 
The actual dose, as received from Pharmaron, will be used for mass balance analysis. 
9.1.3 
Mass Balance Summary Tables 
Summary statistics (ie n, mean, SD, coefficient of variation [CV%], median, minimum 
and maximum) will be presented for amount excreted (Ae) and recovery (%Ae) by 
collection period for the following: 
 
urine [ie Ae(urine) and %Ae(urine)] for total radioactivity 
 
faeces [ie Ae(faeces) and %Ae(faeces)] for total radioactivity 
 
urine and faeces combined [ie Ae(total) and %Ae(total)] for total radioactivity 
In addition, summary statistics (ie n, mean, SD, CV%, median, minimum and maximum) 
will be presented for the cumulative excretion (CumAe) and cumulative recovery 
(Cum%Ae) by collection period for each of the following:  
 
urine [ie CumAe(urine) and Cum%Ae(urine)] for total radioactivity 
 
faeces [ie CumAe(faeces) and Cum%Ae(faeces)] for total radioactivity 
 
urine and faeces combined [ie CumAe(total) and Cum%Ae(total)] for total 
radioactivity 
Finally, summary statistics (ie n, mean, SD, CV%, median, minimum and maximum) will 
be presented for the cumulative excretion (CumAe) and cumulative recovery (Cum%Ae) 
for the study as a whole for each of the following: 
 
urine [ie CumAe(urine) and Cum%Ae(urine)] for total radioactivity 
 
faeces [ie CumAe(faeces) and Cum%Ae(faeces)] for total radioactivity 
 
urine and faeces combined [ie CumAe(total) and Cum%Ae(total)] for total 
radioactivity 
If any subject withdraws prior to the end of a study visit or if subjects have differing 
collection periods (eg Day 8 for some subjects and Day 10 for others) then a last 
observation carried forward (LOCF) approach will also be used whilst calculating 
cumulative Ae and %Ae (ie CumAe and Cum%Ae), where the last observed value will 
be carried forward to the subsequent collection period. If this is the case, then 2 tables 
will be presented. The first table will have the observed values without the use of LOCF 
so the number of subjects may reduce over time and the second table will have the LOCF 
values included so that the number of subjects will remain constant over time. Table 
numbering will be revised as applicable.

Mass Balance Figures 
Arithmetic mean cumulative excretion (ie CumAe) and cumulative recovery (ie Cum%Ae) 
vs time curves will be produced on a linear/linear scale and will include ± SD bars. These 
plots will be produced for CumAe and Cum%Ae, separately, with urine, faeces and total 
overlaid. 
In addition, individual cumulative excretion (ie, CumAe) and cumulative recovery (ie, 
Cum%Ae) vs time curves will be produced on a linear/linear scale. These plots will be 
produced for CumAe and Cum%Ae, separately, with urine, faeces and total overlaid. 
A legend identifying each profile (ie urine, faeces and total) will be displayed on the mean 
plots. Mean figures will be produced using the LOCF imputation strategy (see 
Section 9.1.3) if summary tables are produced using this method. 
9.1.5 
Mass Balance Listings 
The sample collection data (eg collection times) for all urine and faecal samples will be 
listed by subject for enrolled subjects. In addition, all total radioactivity concentrations, 
urine and faecal weights and all mass balance parameters will be listed per subject. 
For urine and feces, where a subject has failed to void over a particular collection interval, 
the amount excreted (Ae) will be listed as “NS” in the data listings. 
Concentrations that are not detected (ie, < limit of detection (LOD)), will be listed as “ND” 
in the data listings.

Statistical Analysis of Mass Balance Parameters 
No formal statistical analysis is required for the mass balance data in this study. 
Descriptive statistics are considered adequate for a study of this type.

Pharmacokinetic Parameter Estimation and Reporting 
Charles River will provide plasma concentration data for MD1003, bisnorbiotin and biotin 
sulfoxide. Pharmaron will provide plasma and whole blood concentration data for total 
radioactivity. 
The PK parameters for MD1003, bisnorbiotin, biotin sulfoxide and total radioactivity in 
plasma (only) will be estimated by Quotient, where possible and appropriate for each 
subject using Phoenix WinNonlin software (v8.0 or a more recent version, Certara USA, 
Inc., USA).

Rules for Pharmacokinetic Parameter Estimation using WinNonlin 
The imputation of non-numerical or negative values reported in the input data set will be 
performed as follows: 
 
pre-dose sample times will be entered as zero 
 
values that are below the limit of quantification (BLQ) or not detected (ND) will be 
entered as zero

 
should partial AUCs be required then values that are BLQ or ND after Cmax may be 
imputed as zero for these partial areas if lambda-z cannot be determined 
 
values that are quantifiable after at least 2 consecutive BLQ or ND values after Cmax 
will be treated as missing for the calculation of PK parameters 
 
values that are reported as “No Result” (NR) or “No Sample” (NS) etc. will be treated 
as missing 
PK parameters will be estimated using standard Phoenix WinNonlin methods, details of 
which may be found in the documentation accompanying the WinNonlin software 
package. The following constraints will apply:

Sampling times 
Actual 
Trapezoidal method

At least 3, not including Cmax 
Minimum requirements for AUC

Rounded dose level   
3 significant figures  
 
Prior to PK parameter estimation the bioanalytical data may be corrected to account for 
the proportion of administered [14C] material not measured due to the use of a [12C] LC-
MS/MS analysis method. Data correction will only be performed if the [14C]-contribution 
exceeds 1 % of the dose administered. If required, MD1003 bioanalytical data will be 
multiplied by the determined data correction factor in SAS by the lead statistical 
programmer (or designee). 
Where possible, the terminal elimination rate constant (lambda-z) will be calculated for 
all subjects. The value of lambda-z will be determined by the slope of the regression line 
of the natural log transformed concentrations vs time.  
The WinNonlin determined choice of data points for determination of lambda-z will be 
reviewed by the pharmacokineticist who may adjust the selection in order to provide a 
more appropriate fit. The choice of data points for determination of lambda-z for each 
profile will be confirmed following a documented peer review.  
Total radioactivity whole blood to plasma ratios will be determined using SAS by the Lead 
Statistical Programmer (or designee) at the time points: 1, 4, 8, 12, 24, 48, 72, 96 and 
168 h. If either the blood or plasma concentration values are ND (ie <LOD) at any given 
time point the ratio will not be calculated. 
When converting blood collection weights to blood volume (if required) for the calculation 
of the whole blood to plasma ratios, the following conversion factor will be used: 
1.06 g of blood = 1 mL of blood 
This will be calculated in SAS as follows: 
Blood weight (g) / 1.06 = Blood volume (mL)

Alternatively, where total radioactivity concentrations in blood have been provided in 
mass unit/g units the following conversion will be performed using SAS: 
Concentration (mass units/g) * 1.06 = Concentration (mass units/mL) 
Metabolite to parent ratios (MPR) after a single dose administration will be calculated as 
follows using Cmax, AUC(0-last) and AUC(0-inf). If for any reason the AUC(0-inf) is not 
calculable then an alternative AUC such as AUC(0-t) over a partial area may be used 
and will be agreed with MedDay:  
MPR = AUC or Cmax (metabolite)
AUC or Cmax (parent)
×
MW (parent)
MW(metabolite) 
 
Correcting for molecular weight (MW): 
 
parent (MD1003) MW = 244.31 g/mol 
 
metabolite (bisnorbiotin) MW = 216.26 g/mol 
 
metabolite (biotin sulfoxide) MW = 260.31 g/mol 
In addition, total exposure ratios (TER) will be calculated for MD1003, bisnorbiotin and 
biotin sulfoxide as follows using Cmax, AUC(0-last) and AUC(0-inf):  
TER(parent) =
AUC or Cmax (parent)
AUC or Cmax (parent + metabolites) 
TER(metabolite) =
AUC or Cmax (metabolite)
AUC or Cmax (parent + metabolites) 
 
Note that each analyte will be corrected by it’s own MW (as given above) for calculation 
of TER. 
9.2.3 
Bioanalytical and Pharmacokinetic Reporting Specifications 
PK parameters for each subject will be reported according to the definitions and rounding 
specifications provided in Table 2. The following flags/footnotes may be applied to the 
PK parameters: 
Flag 
Footnote 
a 
Rsq of regression was <0.9 
b 
Period used for regression analysis was less than 2-fold the calculated half-life 
c 
Extrapolated portion of AUC(0-inf) >20% 
d 
Insufficient post-Cmax data points for estimation of lambda-z 
e

In the event that the Rsq of regression was <0.9 (“a” flag) or the extrapolated portion of 
AUC(0-inf) >20% (“c” flag), then lambda-z, AUC(0-inf) and the parameter estimates 
derived using lambda-z and/or AUC(0-inf) will be deemed unreliable and will be listed 
but excluded from the summary statistics. 
In the event that the period used for regression analysis was less than 2-fold the 
calculated half-life (“b” flag) parameter estimates derived using lambda-z will be listed, 
flagged and included in summary statistics. 
Additional flags may be applied based on emerging data. 
9.2.4 
Bioanalytical and Pharmacokinetic Summary Tables 
Summary statistics (ie n, mean, SD, CV%, median, minimum, maximum, geometric n, 
geometric mean, geometric SD and geometric CV%) will be calculated for the following 
concentration data where possible: 
 
plasma concentrations of MD1003 by time point  
 
plasma concentrations of bisnorbiotin by time point  
 
plasma concentrations of biotin sulfoxide by time point  
 
plasma concentrations of total radioactivity by time point  
 
whole blood concentrations of total radioactivity by time point  
 
whole blood:plasma concentration ratio of total radioactivity by time point  
Values reported in the plasma and whole blood concentration data (ie values that are 
BLQ or ND) will be entered as zero for the determination of summary statistics with the 
exception of geometric mean parameters where BLQ or ND values will be imputed as 
half the LLOQ or LOD value. Data recorded as NR or NS will be handled as missing, ie 
no assumption will be made about the actual concentration. 
Summary statistics (ie n, mean, SD, CV%, median, minimum and maximum) will be 
calculated for all plasma PK parameters. Geometric n, geometric mean, geometric SD 
and geometric CV% will be presented for all PK parameters except Tlag and Tmax. 
These summary statistics will be calculated for relevant plasma PK parameters relating 
to the following: 
 
MD1003 
 
bisnorbiotin 
 
biotin sulfoxide 
 
total radioactivity  
If applicable, data recorded as “Not Calculated” (NC) will be handled as missing.  
9.2.5 
Bioanalytical and Pharmacokinetic Figures 
Mean and individual concentration plots will be produced for each of the following: 
 
plasma concentrations of MD1003, bisnorbiotin, biotin sulfoxide and total 
radioactivity on same plot  
 
plasma and whole blood concentrations of total radioactivity on the same plot

Individual concentration vs time plots (using actual sampling times after dosing) will be 
produced on the linear/linear and the log10/linear scale for each individual subject. 
Mean concentration vs time (using nominal times) plots will be produced on the following: 
 
linear/linear scale using arithmetic mean concentrations (error bars ± arithmetic SD) 
 
log10/linear scale using geometric mean concentrations (error bars x/÷ geometric 
SD) 
Separate concentration vs time (using actual sampling time) plots displaying 1 line per 
subject will be produced on the linear/linear and the log10/linear for each of the following: 
 
plasma MD1003 
 
plasma bisnorbiotin 
 
plasma biotin sulfoxide 
 
plasma total radioactivity  
 
whole blood total radioactivity 
Where curves from multiple analytes or subjects are overlaid on the same plot, symbols 
will be used to identify different analytes/subjects. A legend will be included on these 
plots to define the symbols used in identifying different profiles. 
For all plots on a linear/linear scale, concentration values reported as BLQ or ND will be 
set to zero. For all plots on a log 10/linear scale then concentration values reported as 
BLQ will be set to ½ x LLOQ or LOD and pre-dose samples on Day 1 will not be plotted.

Bioanalytical and Pharmacokinetic Listings 
The sample collection data (eg collection times) for PK samples will be listed by subject. 
In addition, all concentration data including individual ratios (total radioactivity whole 
blood:plasma) and PK parameters will be listed on a per subject basis. Any flags used 
will be provided in listings with the appropriate definition.

Meal Details 
Meal details as recorded on the eCRF as sponsor data will be listed. Any recorded 
deviations from the planned meal times will be listed as protocol deviations. 
10.3 
Adverse Events 
Throughout the study, all AEs will be evaluated by the principal investigator (PI) and 
noted in the AE section of the eCRF. An AE is any untoward medical occurrence in a 
subject that occurs either before dosing (referred to as a pre-dose AE) or once a 
medicinal product has been administered (referred as TEAEs), including occurrences 
which are not necessarily caused by or related to that product. 
AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA v22.1, 
or most recent version), and reported by system organ class (SOC) and preferred term 
(PT). 
AEs will be classified into the following categories: 
 
pre-dose AEs: AEs recorded at screening or with a start date and time prior to the 
dose of IP  
 
treatment-emergent adverse events (TEAEs): AEs that commence during/after the 
dose of IP or commence before dose of IP (ie a pre-dose AE or existing medical 
condition) but worsen in intensity during exposure to IP 
Where the severity of a pre-dose AE intensifies during/after dosing this will be defined 
as a new AE and classified as a TEAE. 
Adverse events will be classified as “unrelated”, “possibly related” and “related” when 
considering their relationship to IP. Adverse drug reactions (ADRs) are any AE where a 
causal relationship with the IP is at least reasonable possibility ie “possibly related” or 
“related”. Pre-dose AEs will always have the classification of “unrelated”.  
Adverse events will be classified as “mild,” “moderate” or “severe” when considering their 
severity. 
If the severity or relationship to IP of a TEAE is missing, the severity/relationship will be 
tabulated as “severe”/”related” in the summary tables ie a worst case scenario will be 
assumed. 
Where the start date of an AE is missing and the stop date is on or after the day of dosing 
of IP or both the start and stop dates are missing then a “worst-case” scenario will be 
assumed, ie the AE is assumed to have occurred post-dose and is therefore considered 
treatment-emergent. If a partial start date/time is available then the event will be 
considered as treatment-emergent unless the partial information suggests otherwise. 
10.3.1 
Summary Tables for Adverse Events 
All pre-dose AEs (as defined in Section 10.3) will be excluded from the summary tables 
but will be listed for all enrolled subjects.  
Descriptive statistical methods will be used to summarise the TEAE data.

The number and percentage of subjects reporting each TEAE will be summarised for 
both SOC and PT. For summaries by SOC and PT, the number of subjects and the 
number of events will be summarised.  
For counts of subjects experiencing events the following will apply: 
 
a subject with a TEAE in more than one body system will be counted once in the 
total number of subjects with TEAEs; 
 
a subject with more than 1 TEAE in the same SOC counts only once at the SOC 
level; 
 
a subject with more than 1 TEAE in the same PT counts only once at the PT level. 
For event counts, all events are included.

13 Overall Considerations 
13.1 
Statistical Programming and Analysis 
The Data Sciences Department at Quotient will perform the statistical programming and 
analysis to produce all analysis datasets and TFLs using the statistical SAS Software 
v9.4.

In general terms, categorical data will be presented using counts and percentages, whilst 
continuous variables will be presented using n, mean, SD, median, minimum and 
maximum. For PK data additional statistics including CV%, geometric n, geometric 
mean, geometric SD and geometric CV% will be presented, as appropriate. The 
geometric n is the number of subjects included in the calculation of the geometric mean, 
geometric SD and geometric CV%. 
The geometric mean is obtained by applying a natural log transformation to the raw data, 
calculating the arithmetic mean of the transformed values and then back transforming 
the arithmetic mean. 
The following formula will be used to calculate the geometric SD: 
 
ie a natural log transformation is applied to the raw data, the arithmetic SD of the 
transformed values is calculated, and then the arithmetic SD of the transformed values 
is back transformed. 
The following formula will be used to calculate the geometric CV%: 
 
ie a natural log transformation is applied to the raw data, the arithmetic SD of the 
transformed values is calculated. This value is then squared. The square value is back 
transformed and a value of 1 is subtracted from the back transformed value. A square 
root is then applied and the resulting value is multiplied by 100. 
In general summary statistics will be presented as detailed in Table 6 below, unless 
otherwise stated:

i refers to the number of decimal places reported in the eCRF or other appropriate source data for the original 
data. Where bioanalytical or PK data are received rounded in significant figures rather than decimal places, 
summary statistics will be supplied to the same precision. 
Details of how the individual mass balance and PK parameters will be presented are 
detailed in Section 9.1.1 and Section 9.2.1, respectively. Where data requires rounding,

values ending with 1 to 4 will be rounded down and values ending with 5 to 9 will be 
rounded up. 
All data listings will be based on all enrolled subjects (see Section 3.2.1). Details of age 
and sex will be included on all data listings. 
If any baseline measurements are found to be missing then consideration will be given 
to imputation using the preceding time point (eg Screening, Admission, if applicable). 
Unscheduled assessment may be used if appropriate. Details of any such imputations 
will be documented as part of the safety population. 
There will be no other imputations for the safety data with regard to missing values or 
study discontinuation (ie subjects who do not complete the study). Imputation for mass 
balance parameter estimation using SAS Software is described in Section 9.1.2 and for 
PK parameter estimation using WinNonlin is described in Section 9.2.2. 
If partial dates are available for smoking history, prior medications or medical/surgical 
history, there will be no date imputations. The data listings will only show the date 
information for the date part that is available eg if only the year part of the date is available 
then YYYY will be presented in the listing. If the full date information is missing, then this 
will be presented as missing on the data listing. 
13.2 
Quality Control of Summary Tables, Figures and Listings and Statistical 
Analysis 
Isolated data errors detected as a result of the QC checks that are deemed significant 
(ie errors that would impact the interpretation of the results in relation to the study 
objectives) will be corrected as per the data management plan. Systematic data errors 
will be investigated further. The data will be corrected if necessary, and the appropriate 
table, figure, and/or listing re-generated and then re-checked. 
In addition to QC checks, a documented peer review will be performed of all SAS 
Software-generated report standard summary tables, figures and data listings, including 
a review of SAS Software code and program log files. 
13.2.1 
Quality Control - Summary Tables 
Manual QC methods (ie comparison of results in the table to results calculated by a 
calculator or spreadsheet) will be used for all summary tables. All summary tables will 
be QC’d as follows: 
 
for tables with no time points, all summary statistics will be QC’d 
 
for tables with time points, at least one time point in each table will be QC’d – different 
combinations of time point will be selected across tables 
 
where tables are produced using a macro for multiple parameters, a minimum of 3 
tables, using treatment and time point as appropriate, will be QC’d 
 
for AEs, the treatment details will be 100% QC’d against the treatment allocation list 
for all subjects 
 
AE summary tables will be 100% checked using the relevant data listing

13.2.2 
Quality Control - Figures 
All figures will be QC’d manually using the corresponding/appropriate summary table or 
data listing, as follows: 
 
all data points for treatment will be checked 
 
where figures are produced using a macro for individual subjects and/or multiple 
parameters, a minimum of 3 figures will be QC’d 
 
mean figures will be QC’d using the corresponding summary table 
13.2.3 
Quality Control - Data Listings 
All data listings will be subjected to a 100% manual check against the eCRF or other 
appropriate source data for a minimum of 2 subjects. If appropriate, the subjects checked 
will include at least one subject who withdrew early from the study. 
14 SAS Data Transfer 
All study data used for analysis and reporting will be transferred to MedDay on issue of 
the final CSR. Datasets will be provided in SAS transport file format (XPT), each dataset 
will be in an individual transport file and will be performed in compliance with SDTM 
(IG v3.2) and ADaM (IG v1.1). This will include define.xml (v2.0) output as well as a Data 
Reviewers Guide (one for SDTM and one for ADaM) in PDF which will be linked to the 
ADaM define.xml. The define.xml will be issued on finalisation of the CSR. 
In addition, copies of reporting SAS programs will be provided with the final data transfer 
(as executable files). This transfer will also include SDTM/ADaM specs, ‘raw’ database 
extract datasets, external vendor datasets (with transfer specs) and the database and 
dataset annotated eCRFs. 
15 Programming Conventions 
Quotient standards for layout of tables, figures and data listings and programming 
conventions will be used as follows: 
 
courier new, font size 8 
 
landscape 
 
A4 paper 
Tables and listings will be produced as MS Word 2016 documents and figures will be 
produced as RTF and PDF files. Listings will be sorted by subject ID number. 
The mock tables (Section 20) presented are a representation of Quotient reporting 
standards. However these are provided for illustrative purposes only. The numbering 
and titles of all TFLs and the formatting, labelling, footnotes and cosmetic appearance of 
tables may be modified or additional labelling/footnotes may need to be added during 
analysis and reporting, for clarification purposes. Any such changes will not be regarded 
as changes to planned analyses.

a Discharge from clinical unit; subjects may be discharged earlier if a cumulative mass balance recovery of 90% % has been achieved or if <1% of the dose 
administered has been collected in urine and faeces within 2 separate consecutive 24 h periods. If the criteria are not met by Day 8, this may result in the extension 
of the residency period for the subjects not achieving the release criteria up to a maximum of an additional 48 h (up to Day 10) for further collection of urine and/or 
faeces. If the criteria are still not met by Day 10, or if additional residency is not considered appropriate or necessary, then home collections of urine and/or faeces 
may be requested at the discretion of the investigator for individual subjects 
b Targeted (symptom driven) physical examination  
c Haematology and clinical chemistry at each time point including virology at screening (see protocol for a full list of clinical laboratory parameters). Creatinine 
clearance will be estimated at screening from plasma creatinine using the Cockcroft-Gault equation for eligibility purposes
