Brief summary:
Human, absorption, metabolism and excretion study of belumosudil (KD025)

Detailed description:
This is an open-label, 2-part study designed to assess the absolute bioavailability of belumosudil (KD025) and to determine the mass balance recovery, metabolite profile, and identification of metabolite structures for \[14C\]-KD025 in healthy male subjects.

Primary Objectives

* To determine the absolute oral bioavailability of KD025 (Part 1)
* To determine the mass balance recovery after a single oral dose of \[14C\]-KD025 (Part 2)
* To provide plasma, urine, and fecal samples for metabolite profiling and structural identification (Part 2)

Secondary Objectives

* To obtain information regarding the oral PK of total radioactivity, KD025 and its metabolites KD025m1 and KD025m2, in plasma
* To obtain information regarding the intravenous (IV) pharmacokinetics (PK) of \[14C\]-KD025 in plasma (Part 1)
* To determine the routes and rates of elimination of \[14C\]-KD025 and associated total radioactivity (Part 2)
* To evaluate the extent of distribution of total radioactivity into blood cells (Part 2)
* To assess the qualitative and quantitative metabolic profile of \[14C\]-KD025 and carry out the structural elucidation of the main metabolites in plasma (accounting for ≥ 10% of circulating total radioactivity) and in urine and fecal samples accounting for ≥ 10% of administered dose (Part 2)
* To provide additional safety and tolerability information for belumosudil

PART 1:

Part 1 is an open-label, non-randomized single oral dose followed by an IV microtracer assessment in 5 healthy male subjects. Subjects receive a single oral dose of belumosudil (KD025) 200 mg Tablet (Treatment A), in the fed state following a standard breakfast on the morning of Day 1. Subjects then receive an IV dose of 100 μg \[14C\]-KD025 (a 'microdose') containing not more than (NMT) 37 kBq (kilobecquerel; 1000 nanocurie \[nCi\]) \[14C\], as a 15 min IV infusion (Treatment B), beginning 1.75 hours (h) after the oral dose administration (Treatment A), i.e., 15 minutes \[min\] before the expected time of maximum concentration \[Tmax\] 2 h) for the oral dose.

Planned enrollment is to be 6 subjects to ensure 4 evaluable subjects. An evaluable subject for Part 1 will be defined as a subject who had sufficient data for evaluation of the primary oral bioavailability objective of the study.

All subjects are to undergo preliminary screening procedures to determine their eligibility for Part 1 and Part 2 at the screening visit (Day -28 to Day -2 of Part 1). Subjects are to be admitted to the clinical unit on the evening prior to investigational medicinal product (IMP) administration (Day -1 of Part 1) for confirmation of eligibility and baseline procedures. Subjects will be dosed on the morning following admission (Day 1 of Part 1). Following an overnight fast (approximately 10 h), subjects are to consume a standard breakfast and receive a single dose of Belumosudil 200 mg Tablet (Treatment A) 30 min after the start of breakfast. At 1 h 45 min (1.75 h) after Treatment A administration, subjects are to receive an IV infusion of \[14C\]-KD025 solution, 100 µg (Treatment B). Subjects are to remain resident in the clinic until up to 48 hours post-oral dose (up to Day 3). The minimum washout period between dose administrations in Part 1 and 2 is 7 days.

PART 2:

Part 2 is an open-label, non-randomized absorption, distribution, metabolism, and elimination (ADME) assessment in 5 healthy male subjects. Following a minimum washout period of 7 days, subjects who participated in Part 1 of the study are to be admitted to the clinical unit for participation in Part 2 of the study. Subjects are to receive a single oral administration of \[14C\]-KD025 200 mg Capsule containing NMT 9.8 MBq (266 µCi) \[14C\] (Treatment C) in the fed state following a standard breakfast on the morning of Day 1.

A subject in Part 2 will be considered evaluable if they had provided biological samples for up to 168 hours after drug administration or demonstrates \>90% mass balance recovery, or \< 1% of the administered dose eliminated in excreta for 2 consecutive days, whichever was sooner.

Approximately 7 days after subjects are discharged from Part 1 of the study, subjects are to be admitted to the clinical unit on the evening of the day prior to IMP administration (Day -1 of Part 2) for confirmation of eligibility and baseline procedures.

Subjects are to be dosed on the morning following admission (Day 1 of Part 2). Following an overnight fast (approximately 10 h), subjects consume a standard breakfast and receive a single dose of \[14C\]-KD025 200 mg Capsule (Treatment C) 30 min after the start of breakfast. Subjects are to remain in the clinic until up to 168 hours after dosing (up to Day 8 of Part 2). The plan is for subjects to be released as a group when all subjects had achieved a mass balance cumulative recovery of \> 90% or if \< 1% of the dose administered had been collected in urine and feces within 2 separate consecutive 24-hour 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 is achieved, the subjects are to undergo discharge assessments; collection of all samples (blood, urine and feces) is stopped.

If mass balance criteria has 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 216 h post-dose (Day 10 of Part 2). During the additional residency period, only urine and/or feces are to be collected. If the criterion is still not met by Day 10, or if additional residency not considered appropriate or necessary, then home collections of urine and/or feces may be requested at the discretion of the Investigator for individual subjects. To ensure ongoing well-being of subjects, a follow-up phone call will take place 5 to 7 days post-discharge from the study or after the end of the last collection period.

Part 1 Study Design 
All subjects will undergo preliminary screening procedures to determine their eligibility for 
Parts 1 and 2 of the study at the screening visit (Day -28 to Day -2 of Part 1). Subjects will be 
admitted to the clinical unit on the evening prior to investigational medicinal products (IMPs) 
administration (Day -1) for confirmation of eligibility and baseline procedures. Subjects will be 
dosed on the morning following admission (Day 1). Following an overnight fast (approximately 
10 h), subjects will consume a standard breakfast and will receive a single dose of KD025 
(Treatment A) 30 min after the start of breakfast. One hour and 45 min post Treatment A 
administration, subjects will receive an IV infusion of [14C]-KD025 solution (Treatment B). 
Subjects will remain resident in the clinic until up to 48 h post-oral dose (up to Day 3). The 
minimum washout period between dose administrations in Part 1 and 2 will be 7 days. 
Part 2 Methodology: 
Part 2 is an open-label, non-randomised absorption, distribution, metabolism, excretion 
(ADME) assessment in 6 healthy male subjects. Following a minimum washout period of 7 
days, subjects who participated in Part 1 of the study will be admitted to the clinical unit for 
participation in Part 2 of the study. On Day 1 each subject will receive a single oral 
administration of 200 mg [14C]-KD025 capsule containing (NMT 9.8 MBq) (215 pCi) [140] 
(Treatment C) on the morning of Day 1 after a standard breakfast.

Part 2 Study Design 
Approximately 7 days after subjects have been discharged from Part 1 of the study, subjects 
will be admitted to the clinical unit on the evening of the day prior to IMP administration 
(Day -1) for the confirmation of eligibility and baseline procedures. Subjects will be dosed on 
the morning following admission (Day 1). Following an overnight fast (approximately 10 h), 
subjects will consume a standard breakfast and will receive a single dose of [14C]-KD025 
capsule (Treatment C) 30 min after the start of breakfast. Subjects will remain resident in the 
clinic 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, the 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 216 h 
post-dose (Day 10). During the additional residency period only urine and/or faeces will be 
collected. 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 requestOd at 
the discretion of the investigator for individual subjects. To ensure ongoing wellbeing of the 
subjects, a follow-up phone call will take place 5 to 7 days post-discharge from the study or 
after the end of the last collection period.

Background Information 
5.1 	
Introduction 
Rho-associated coiled-coil protein kinases (ROCKs) are members of the 
serine/threonine kinase family, often studied for their role in cell morphology, motility and 
shape through effects on the cytoskeleton [1][2]. Two ROCK isoforms have been 
identified, ROCK1 and ROCK2. Both are involved in Rho-mediated changes in the 
actin/myosin cytoskeletal network. ROCK1 and ROCK2 are not redundant signalling 
molecules and may serve different functions within cells [3][4][5]. Recent research has 
uncovered additional roles for ROCK signalling, particularly ROCK2, in conditions 
including autoimmune disease aggravated or caused by a 1-helper (Th)17-polarised 
T cell response [6] and pulmonary fibrosis [7]. 
Rho GTPase-mediated signalling pathways play a central role in coordinating and 
balancing T cell mediated immune responses, including T cell receptor-mediated 
signalling, cytoskeletal reorganisation, and the acquisition of the appropriate T cell 
effector program [8]. Recent studies have demonstrated that aberrant activation of 
ROCK2 leads to induction of interleukin (IL)-17 and IL-21 via interferon regulatory factor 
4-dependent mechanism [9]. 
In addition, ROCK activity was found to be up-regulated in patients with rheumatoid 
arthritis (RA) and systemic lupus erythematosus (SLE) [10] and inhibition of ROCK2 
effectively decreased IL-17 production in vivo and demonstrated efficacy in arthritis and 
lupus mouse models. Autoimmunity also involves alterations to regulatory T cells (Tregs) 
that suppress activation of the immune system and play a critical role in maintaining 
immunological tolerance to self-antigens and inhibiting autoimmune responses [11]. 
ROCK2 inhibition may increase the suppressive function of Tregs. 
ROCK is also downstream of several major pro-fibrotic mediators, including: 
transforming growth factor beta (TGF-(3), connective tissue growth factor (CTGF), and 
lysophosphatidic acid (LPA). A defining feature of pathologic fibrosis is the differentiation 
of fibroblasts to myofibroblasts, a process mediated by ROCK. In addition, ROCK 
mediates stress fibre formation and regulates the transcription of pro-fibrotic genes, 
including CTGF and alpha-smooth muscle actin (a-SMA). Further, ROCK inhibition has 
demonstrated anti-fibrotic activity in murine models [12]. 
KD025 (formerly called SLx-2119), (2-(3-(4-(1H-indazol-5-ylamino) quinazolin-2-y1) 
phenoxy)-N-isopropylacetamide-methane sulfonic acid salt) is an orally available 
ROCK2 selective inhibitor that is currently in Phase II clinical development for treating 
autoimmune and fibrotic disorders. 
Pre-clinical investigations have identified that KD025 is metabolised via first pass 
metabolism to 2 main metabolites KD025m1 and KD025m2 in the species dosed. 
6.2 Investigational Medicinal Product(s) 
The following investigational medicinal products (IMPs) will be used in this clinical study

Previous Study Findings 
5.3.1 	
Non-clinical Data Summary 
Nonclinical pharmacology studies demonstrate the potential of KD025 to have a 
therapeutic benefit in a number of indications, particularly in autoimmune disease 
through effects on Th17-type immune responses, and idiopathic pulmonary fibrosis (IPF) 
through anti-fibrotic mechanisms [12]. 
Solubility of KD025 is pH dependent ie, it is 100 pg/mL at pH 2.7, -4 pg/mL at pH 6.5 
and -3 pg/mL at pH 7.4. The lower solubility at higher pH could potentially impact 
absorption of KD025 under physiological conditions. 
KD025 plasma exposure generally increased with dose, was dose proportional or greater 
than dose proportional, and showed some accumulation. The elimination half-life of 
KD025 was variable in nonclinical studies with calculated values of approximately 2 h in 
mice, 1 to 7 h in rat and rabbit, and 1 to 3 h in dog. 
KD025 undergoes first pass metabolism in all evaluated species after oral administration 
to form a ROCK2 active metabolite, KDO25m1 and a metabolite that is relatively less 
active against ROCK2, KD025m2. 
Distribution studies performed in rats with oral administration of carbon-14 [14q-KD025 
demonstrated distribution primarily into tissues associated with elimination 
(gastrointestinal [GI], liver, kidney, urinary bladder), adrenal gland, and exocrine 
glandular tissue. All tissues demonstrated clearance and no appreciable radioactivity 
was observed in the brain. Melanin-containing tissues (uveal tract and pigmented skin) 
demonstrated higher tissue retention, indicating some affinity of KD025 for melanin.

[14C]-KD025 excretion was similar in male and female rats and was predominantly via 
the faecal route (-90%), while urine accounted for a smaller proportion of excretion 
(<1%). 
Based on in-vitro assessment, cytochrome P450 (CYP)3A4 and CYP1A2 were the 
predominant CYP isoforms responsible for the metabolism of KD025, although CYP2C8, 
CYP2D6 and Uridine 5'-diphospho-glucuronosyltransferase (UGT)1A9 may also 
contribute to a lesser extent. Metabolism of KD025 to KDO25m1 was CYP3A4 and 
CYP2C8 dependent. Metabolism of KD025 to KD025m2 was CYP3A4 dependent with 
further metabolism of KD025m2 dependent on UGT1A1 with no to little contribution from 
CYP enzymes. 
KD025 and the active metabolite KDO25m1 is > 99% bound to human, dog and rat 
plasma proteins. KD025m2 is > 99% bound to human plasma protein. 
Good laboratory practice (GLP)-compliant rat and dog general toxicology/toxicokinetic 
studies of acute, sub-chronic (1 and 3 month), and chronic (6-month rat and 9-month 
dog) duration have been completed. In addition, safety pharmacology studies evaluating 
human ether-a-go-go related gene (hERG) (in-vitro), central nervous system (rat), 
respiratory (rat), and cardiovascular (dog) organ systems have been completed. 
Embryo-foetal toxicology (rat and rabbit) and fertility (rat) studies have also been 
completed. Furthermore, KD025 has been evaluated in a panel of studies evaluating 
drug genotoxicity and phototoxicity potential. The primary non-clinical toxicology finding 
at/near clinically relevant exposures were limited to changes in the cardiovascular (blood 
pressure lowering), hepatic (transaminitis, hypertrophy/increased organ weight, and 
cholestasis/inflammation), renal (increased blood urea nitrogen [BUN], tubular changes, 
pigmentation and intracellular protein droplets in the epithelium), GI (decreased 
appetite), and hematopoietic/immunologic (anemia with regeneration and thymic/splenic 
lymphoid depletion) systems. In addition, KD025 demonstrated embryo-foetal 
toxicity/teratogenicity as well as reduced male fertility (reduced fertility index/sperm 
concentration/motility and increased abnormal sperm percentage; testes/epididymis 
[decreased organ weights and degenerative histopathology]). Male fertility findings were 
generally at higher than clinically relevant exposures. 
Data from these nonclinical studies support a thorough understanding of the potential for 
safety-related effects of KD025 and have facilitated the development of the current 
clinical trial monitoring plan. Further details of non-clinical studies can be found in the 
Investigator's Brochure (IB) [12]. 
5.3.2 	
Clinical Data Summary 
To date, 7 clinical studies have been completed, consisting of 6 Phase I clinical studies 
(SLx-2119-09-01, KDO25-101, KDO25-102, KDO25-103, KDO25-105, and KDO25-106) in 
healthy subjects, and 1 Phase Ila study (KD025-205) in subjects with psoriasis vulgaris. 
Additionally, a Phase II study (KD025-206) in subjects with psoriasis vulgaris has been 
clinically completed; however, the clinical study report is pending. In addition to the 
completed studies, 5 Phase II studies are ongoing in subjects with chronic graft versus 
host disease (cGVHD) (KD025-208 and KD025-213), IPF (KD025-207), psoriasis 
(KDO25-211) and systemic sclerosis (KD025-209). A drug-drug interaction phase 1 study 
is currently ongoing (KDO25-107).

KD025 was generally well-tolerated, with most adverse events (AEs) considered mild or 
moderate in severity and a low incidence of serious adverse events (SAEs) overall. An 
increase in liver function test AEs at the highest dose tested in Phase 2 studies (400 mg 
twice daily [BID]) (Study KD025-206) led to this dose no longer being used in subsequent 
studies. 
The most common (5% overall) AEs were alanine aminotransferase (ALT) increased 
(10.8%), nausea (9.7%), diarrhoea (8.9%), upper respiratory tract infection (8.9%), 
fatigue (7.8%), aspartate aminotransferase (AST) increased (7.8%), gamma-
glutamyltransferase increased (7.8%), headache (6.3%), cough (6.3%), and dyspnoea 
(5.2%). 
The most common AEs were generally also the most common treatment related AEs. 
The majority of these events were mild to moderate in severity. 
To date no clinically significant AEs suggestive of photo-toxicity have been reported in 
KD025 studies. All but one of the skin and subcutaneous tissues system organ class 
(SOC) events reported to date have been mild to moderate in severity (the exception 
being a Grade 3 "rash erythematous" likely related to progression of cGVHD). Of note, 
most of the subjects treated with KD025 have been enrolled into studies of psoriasis and 
GVHD. 
No treatment related deaths have occurred to date. 
The identified and potential risks noted in association with KD025, detailed in the IB [12], 
are balanced by the anticipated benefits that may be afforded to subjects with psoriasis 
vulgaris, IPF and cGVHD. 
6 Rationale 
6.1 	
Study Rationale 
This study is being conducted to investigate the oral pharmacokinetics (PK), intravenous 
(IV) PK, mass balance recovery and metabolite profiling and identification of 14C-KD025. 
Kadnnon Pharmaceuticals LLC. is developing KD025, a ROCK2 selective inhibitor, for 
the treatment of autoimmune diseases. 
Part 1 
Knowing the absolute bioavailability of an oral drug product is a regulatory requirement 
in some regions, eg Australia. In addition, understanding the bioavailability of a drug and 
the factors that influence absorption, may guide the formulation development strategy. 
The IV microtracer technique is an established methodology for measuring the IV and 
oral kinetics of a drug in the same individuals in a single dosing period. The technique 
involves concurrent administration of a microdose of the drug containing microtracer 
amounts of 14C with a single oral therapeutic dose, which avoids the concerns of 
dose-dependent kinetics when extrapolating IV PK from a microdose, as the systemic 
exposure is at therapeutic concentrations. This design enables measurement of 
14C-labelled drug in the plasma following IV dosing via sensitive accelerator mass 
spectrometry (AMS) techniques, and measurement of the unlabelled parent in the 
plasma by standard high performance liquid chromatography mass spectrometry/mass 
spectrometry (HPLC MS/MS) techniques. Thus, it is possible to obtain the IV PK 
parameters with the associated variability, and calculate the absolute bioavailability. In

addition, because the IV dose administration involves giving a low volume of a low 
concentration of parent drug, an advantage of this approach is that it is much easier to 
develop an IV formulation for microdosing than it would be for a higher clinical dose. 
Part 2 
The current study is designed to collect samples and to generate data for the absorption, 
distribution, metabolism and elimination (ADME) of KD025 in humans, as well as 
generating samples for metabolite profiling and structural identification. 
6.2 Dose Rationale 
Part 1 
KD025 in doses ranging from 20 to 1000 mg once daily (QD) to 500 mg BID have 
generally been well tolerated. A single oral dose of 200 mg of KD025 followed by an 
100 pg IV dose of [14C]-KD025, given 1.75 h after the oral dose has been administered 
(estimated to end at the time of maximum plasma concentration [Tmax] for the oral dose 
[2 h]), has been selected for Part 2 of this study. The 200 mg dose has been well tolerated 
as a.  single dose and in repeat dosing in healthy subjects and patients with psoriasis and 
cGVHD; repeat dosing at 400 mg QD has been well tolerated in patients with cGVHD 
and IPF. The 200 mg dose provides a clear PK profile, in the linear range, well above 
the lower limit of quantification, and is in the expected therapeutic range. 
Part 1 is the absolute bioavailability part of the study where an IV micro dose of KD025 
containing microtracer amounts of 14C is administered following administration of an oral 
dose of KD025 to determine the bioavailability of the oral dose compared with the IV 
dose. According to the International Council for Harmonisation (ICH) M3 guidance, a 
micro dose is a dose that is <1/100th of the pharmacologically active dose up to a 
maximum of 100 pg. In addition, to ensure that the IV micro dose does not contribute 
significantly to the exposure following oral dosing, the IV dose is reduced further and in 
this study will be 1/1000th of the oral dose. 
An IV microtracer dose is one that contains not more than (NMT) 37.0 kBq (1000 nCi). 
This has been selected as it is the standard radioactive dose used in this type of study 
and will be sufficient to meet the objectives of Part 1, but contains a low enough amount 
of radioactivity so as not to cause a significant risk to the subjects. 
Therefore the IV dose for this study will be 100 pg  [14q_KD025 containing NMT 37.0 kBq 
(1000 nCi). This IV dose is 1/2000th of the oral dose administered in this study and 
<1/ 100th of the likely therapeutic dose, and hence is an appropriate 'IV microtracer dose'. 
Part 2 
KD025 in doses ranging from 20 to 1000 mg QD to 500 mg BID have generally been 
well tolerated. A single dose of 200 mg [14q-KD025 has been selected for Part 2 of this 
study. The 200 mg dose has been well tolerated as a single dose and in repeat dosing 
in healthy subjects and patients with psoriasis and cGVHD; repeat dosing at 400 mg QD 
has been well tolerated in patients with cGVHD and IPF. The 200 mg dose provides a 
clear PK profile, in the linear range, well above the lower limit of quantification, and is in 
the expected therapeutic range.

The dose of radioactivity for Part 2 has been determined following review of human 
dosimetry calculations provided by Public Health England (PHE). In accordance with the 
'as low as reasonably practical' principle, the lowest amount of radioactivity will be 
administered that gives confidence that the study objectives will be met. Based on the 
human dosimetry calculations, a radioactive dose of no more than 9.8 MBq (215 pCi) by 
the oral route will be necessary. Adequate metabolite profiling of some key plasma 
samples may not be possible at a radioactive dose less than this. 
Subjects will be participating in both study Parts 1 and 2, therefore the radioactive dose 
for Part 2 will be adjusted to take into account the microtracer amount of radioactivity 
that the subjects will receive in Part 1 of the study (37 kBq/1000 nCi). Thus the oral dose 
for Part 2 will have a radioactive dose containing NMT 9.8 MBq (215 pCi). The total 
committed effective dose subjects will receive is 3 mSv, falling within International 
Commission on Radiological Protection (1992) Guidelines for Category Ilb studies (1 to 
10 mSv). 
To ensure that the [14C] drug products do not exceed the limit for radioactive dose 
approved by the Administration of Radioactive Substances Advisory Committee 
(ARSAC), the target specific activity of the [14C] drug substance will be set at 90% of 90% 
of the threshold radioactive dosing limit. This will ensure provision for a ± 10% range on 
the [14C] drug substance specification for specific activity and a ± 10% range on the [14C] 
drug substance assay in the drug product, thereby providing continued assurance for 
compliance with the ARSAC-approved limit for drug product radioactivity dose. 
A positive food effect has been reported in previous studies and current dosing 
instructions in on-going Phase 2 studies recommend administration of KD025 with food 
[12]. Therefore oral administration of KD025 in this study will be performed in the fed 
state, to ensure characterisation of absorption, metabolism and excretion in conditions 
that best mimic intended clinical use. 
6.3 	
Population Rationale 
The European Medicines Agency (EMA) propose to include subjects in the age group 18 
to 55 years with normal weight who are non-smokers without a history of alcohol or drug 
abuse. The latter criteria are proposed to avoid interaction on drug metabolism and to 
avoid non-compliance. In order to avoid any interaction with other medication, no 
co-medication except 4 g of paracetamol per day (within 24 h) will be allowed. 
We acknowledge the ARSAC Notes for Guidance recommend that wherever possible, 
healthy subjects selected for research projects should be aged over 50 years [13]. 
However, Part 2 of this 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 (NDA). 
Protocol KDO25-108 (C2SC200323) Version 1.0 
17 JAN 2019 
Page 24 of 64 


Sponsor/Quotient Sciences Confidential 
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. 
Formal rat and rabbit embryo-foetal developmental toxicology studies with KD025 
demonstrated potential for embryo-foetal toxicity and/or malformations at clinically 
relevant exposures. Therefore subjects with pregnant partners will be excluded from this 
study. 
The purpose of this study is to investigate the oral pharmacokinetics (PK), intravenous 
(IV) PK, mass balance recovery and metabolite profiling and identification of 14C-KD025. 
It is therefore an advantage to enrol a relatively homogeneous population and to 
minimise variability. Based on the above considerations and target population, healthy 
male subjects, aged 30 to 65 years are considered suitable for this study. 
6.4 	
Risks and Benefits 
6.4.1 	
Potential Risks associated with KD025 
KD025 has generally been well tolerated across the clinical studies conducted. No 
drug-related AEs have resulted in fatal outcomes. The most common AEs associated 
with KD025 administration are liver-related, specifically increased ALT and AST levels, 
but no Hy's Law cases. Subjects will receive single doses of KD025 in this study and will 
be closely monitored throughout the study for any changes in liver enzymes, and no 
subject with a history or presence of hepatic disease or ALT/AST values > the upper limit 
of normal (ULN) will be enrolled in the study (see Section 9.3). 
Other commonly reported events include rash, pruritus, upper respiratory infection, joint 
aches and swelling, headache, fatigue, back pain, leg weakness, diarrhoea, nausea, 
vomiting, upper abdominal pain, increase in white blood cell count, cannula site infection, 
dizziness, and flatulence. 
6.4.2 	
Risks associated with Radiation Exposure 
The [14q-KD025 solution for infusion and [14q-KD025 capsule will contain a radionuclide 
(NMT 9.8 MBq [267 pa]) so subjects will be exposed to ionising radiation. The effective 
dose that each subject will receive from one administration will not exceed 3 mSv. This 
is approximately 1 year and 1 month of the average radiation exposure received in the 
UK each year (2.7 mSv). 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. 
6.4.3 	
Risks associated with exposure to Radiation Microdose 
The IV micro dose to be administered is 2000-fold lower than the oral dose and the 
exposure to [14q-KD025 originating from the infused micro dose is therefore considered 
negligible and no AEs are expected to occur. 
Protocol KDO25-108 (QSC200323) Version 1.0

6.4.4 	
Other considerations 
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. 
Although KD025 nonclinical data suggests the potential for phototoxicity, in standard 
reporting of AEs in Phase 1/2 clinical studies, KD025 has not demonstrated any clinically 
significant phototoxicity. Therefore, for this study no restrictions have been applied. 
The blood volume taken for each subject will be approximately 583.5 mL in a 4 week 
period. To account for this, subjects with blood platelet count, haemoglobin and red blood 
cells lower than the reference range will be excluded from the study. 
There is no benefit to the subjects from taking part in this study. The development of a 
ROCK2-selective small molecule drug has the potential for effectiveness in multiple 
disease indications and will be of benefit to the wider community. 
The overall risk benefit balance is therefore considered to be acceptable.

Study Plan 
This is a single centre, non-randomised, open-label, two-part study in healthy male 
subjects. Six subjects will participate in both parts of the study. 
8.1.1 	
Study Plan Part 1 
Part 1 is an open-label, non-randomised single oral dose followed by an IV microtracer 
assessment in 6 healthy male subjects. On Day 1 subjects will receive a single dose of 
KD025 (Treatment A), in the fed state. Subjects will then receive an IV dose of 
[14q-KD025 (100 pg, a `microdose1) containing NMT 37 kBq (1000 nCi) [14C], as a 15 
min IV infusion (Treatment B), 1.75 h after the oral dose administration (Treatment A) ie,

All subjects will undergo preliminary screening procedures to determine their eligibility 
for Parts 1 and 2 of the study at the screening visit (Day -28 to Day -2 of Part 1). Subjects 
will be admitted to the clinical unit on the evening prior to IMP(s) administration (Day -1) 
for confirmation of eligibility and baseline procedures. Subjects will be dosed on the 
morning following admission (Day 1). Following an overnight fast (approximately 10 h), 
subjects will consume a standard breakfast and will receive a single dose of KD025 
(Treatment A) 30 min after the start of breakfast. One hour and 45 min post Treatment A 
administration, subjects will receive an IV infusion of [14C]-10025 solution (Treatment B). 
Subjects will remain resident in the clinic until up to 48 h post-oral dose (up to Day 3). 
The minimum washout period between dose administrations in Part 1 and 2 will be 
7 days. 
8.1.2 	
Study Plan Part 2 
Part 2 is an open-label, non-randomised ADME assessment in 6 healthy male subjects. 
Following a minimum washout period of 7 days, subjects who participated in Part 1 of 
the study will be admitted to the clinical unit for participation in Part 2 of the study. On 
Day 1 each subject will receive a single oral administration of 200 mg [14q-KD025 
capsule containing (NMT 9.8 MBq) (215 pCi) [14C] (Treatment C) on the morning of Day 1 
after a standard breakfast.

A subject in Part 2 will be considered evaluable if they have provided biological samples 
for up to 168 h after drug administration or have demonstrated >90% mass balance 
recovery, or have <1% of the administered dose eliminated in excreta for two consecutive 
days, whichever is the sooner. 
Approximately 7 days after subjects have been discharged from Part 1 of the study, 
subjects will be admitted to the clinical unit on the evening of the day prior to IMP 
administration (Day -1) for the confirmation of eligibility and baseline procedures. 
Subjects will be dosed on the morning following admission (Day 1). Following an 
overnight fast (approximately 10 h), subjects will consume a standard breakfast and will 
receive a single dose of [14q-KD025 capsule (Treatment C) 30 min after the start of 
breakfast. Subjects will remain resident in the clinic 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, the 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 
216 h post-dose (Day 10). During the additional residency period only urine and/or 
faeces will be collected. If the criterion is still not met by Day 10, or if additional residency

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.

Sponsor/Quotient Sciences Confidential 
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/visit) 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 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 (QTc) interval of >500 msec or increase in QTc interval of 
>60 msec from baseline (confirmed following a repeat ECG) 
- ALT concentration >3 x the upper limit of the reference range 
• Termination of the study 
• Upon the subject's request (withdrawal of consent) 
• Significant deviation from the protocol 
• Concurrent illness or requirement for prohibited medication 
• At the discretion of the investigator/sponsor 
For the purpose of withdrawal criteria in Parts 1 and 2, baseline will be considered as 
the pre-dose Day 1 measurement for each part. 
8.4 	
Subject Replacement 
No replacement subjects are to be used in this study. 
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 (le, a serious adverse event considered at least possibly 
related to the IMP administration) in one subject. 
• Severe non-serious adverse reactions (le, severe non-serious adverse events 
considered as, at least possibly related to the IMP administration) in two subjects in 
the same cohort of the study, 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 Principal 
Investigator (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 and/or dosing 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 after dosing has begun, 
dosing may be suspended pending discussion between the investigator, sponsor and 
potentially the ARSAC practitioner (where discussion is related to administration of 
radiation). 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 	
Lost to Follow-up 
A subject will be considered lost to follow-up if they fail to return for scheduled visits and 
cannot be contacted by the clinical unit. 
If a subject fails to return to the clinical unit for a required study visit: 
The clinical unit must attempt to contact the subject and reschedule the missed visit as 
soon as possible 
Before a subject is deemed lost to follow-up, the investigator or designee must make 
every effort to regain contact with the participant (eg 3 telephone calls on 3 separate 
occasions and, if necessary, an email or letter to the participant's last known email/postal 
address). These contact attempts should be documented in the subject's source.

If the subject cannot be contacted, they will be considered lost to follow-up. 
8.8 	
Treatment Allocation 
This is an open-label, non-randomised study, therefore a randomisation schedule will not 
be produced. A treatment allocation list 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 list will be retained in the Investigator Site File (ISF). 
8.8.1 	
Subject Numbers 
Subject numbers will be allocated on the morning of dosing in Part 1 according to the 
code 001 to 006 using the lowest number available. 
8.8.2 	
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 (TOPS) will be checked to ensure that each subject has not participated in a 
study at another site within at least 3 months 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.

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 study discharge. 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 implantable intrauterine device 
• Surgical sterilisation (for example, vasectomy or partner's bilateral tubal occlusion) 
• Partner's use of female cap or diaphragm (double barrier) 
Alternatively, true abstinence is acceptable when it is in line with the subject's preferred 
and usual lifestyle. If a subject is usually not sexually active but becomes active, they, 
with their partner, must comply with the contraceptive requirements detailed above. 
These contraception requirements are aligned with guidance issued by the Heads of 
Medicines Agency: Clinical Trials Facilitation Group [14]. 
9.4.1 	
Exposure to 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 the sexual partners (both male and 
female). Therefore, a condom should be used by all male subjects throughout the study 
and for 90 days after study discharge.

Sperm Donation 
Male subjects should not donate sperm for the duration of the study and for at least 
90 days after study discharge. 
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 each admission until discharge from each part of the study. 
2. Subjects must not drink liquids or eat food containing grapefruit, cranberry, caffeine 
or other xanthines from 24 h prior to each admission until discharge from each part 
of the study. 
3. Subjects should refrain from eating food containing poppy seeds for 48 h prior to 
screening and for 48 h prior to each admission until discharge from each part of 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 each admission until discharge 
from each part of the study. 
10 Study Procedures 
Study procedures will be performed as detailed in the study schedule of assessments in 
Appendix 2 and Appendix 3 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 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 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 Section 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. 
Subjects will be admitted to the clinical unit on the evening before dosing (Day -1) for 
both Parts 1 and 2. 
The admission and pre-dose procedures are presented in Appendix 2 and Appendix 3. 
10.3 Study Day Procedures 
10.3.1 	
Blood Volume 
The total blood volume for each subject will be approximately 583.5 mL in a 4 week 
period. Subjects with a low blood count will be excluded from participation in this study 
(exclusion criterion 12). 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: 
PK blood 
ECGs 	
Vitals 	
eg physical exams 
sampling 
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 in Part 1 will be timed according to the schedule in Appendix 2. 
All safety assessments in Part 2 will be timed and performed relative to the start of 
dosing.

10.3.3 	
Discharge from the Clinical Unit 
Part 1 
A subject will be allowed to leave the premises following completion of study-specific 
procedures at 48 h post-dose providing that: 
• no AEs have been reported during the study visit 
• the subject responds in the affirmative when asked if they are feeling well 
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. 
Part 2 
A subject will be allowed to leave the premises following completion of study-specific 
procedures at 168 h post-dose 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 a standard breakfast, 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, 
the 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 216 h post-dose (Day 10, 2 additional 24 h 
periods). 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 [16], each subject will receive a card stating the 
telephone number of the investigator.

10.3.5 	
Follow-up 
A follow-up phone call will take place 5 to 7 days after discharge/after the final collection 
period to ensure the ongoing wellbeing of the subjects. If a subject reports any AEs which 
can present a cause for concern, they will be required to attend the clinic for a further 
follow-up assessment (as an unscheduled visit). Completion of the last follow-up call or 
unscheduled follow-up visit will be considered the end of the study.

Dosing of Subjects 
11.1 	
Food and Fluid Intake 
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. In Part 1, the water restrictions before and after dosing only apply to the oral 
dose. 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. 
Breakfast will be controlled by clinical staff members on Day 1 for both study Parts. The 
start and stop time of the meal and the percentage consumed must be recorded in the 
source. 
Subjects will be provided with a light snack and will fast from all food and drink (except 
water) until the following morning, when they will be provided with a standard breakfast. 
The breakfast should be consumed over a maximum period of 25 min, with oral dosing 
occurring 30 min after the start of breakfast. Subjects should be encouraged to eat their 
meal evenly over the 25 min period. It is acknowledged that some subjects will take less 
time to eat, but dosing should still occur 30 min after the start of breakfast. 
The acceptable deviation for the pre-dose meal from the nominal time point is: 
• Pre-dose meal will be provided within ± 5 min of the nominal time point 
Lunch will be provided at approximately 4 h post-dose, an evening meal 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. 
Part 2 only: 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 IMPs and doses to be administered are provided in Section 5.2 and 
Section 8.1.1, respectively. Subjects will be dosed on the morning of Day 1 of each study 
part.

Sponsor/Quotient Sciences Confidential 
Part 1 
Subjects will receive a single oral dose of KD025 in the fed state. 240 mL of water will 
be given immediately following oral administration. One hour and 45 min after the oral 
dose has been administered, an 14C radiolabelled IV dose will be infused over 15 min. 
This infusion will be in the opposite arm being used for PK sampling. 
To assess tolerability of the IV administration, the first subject will be dosed at least 
30 min prior to dosing the second subject. All subsequent dosing of the IV formulation 
will be staggered by at least 15 min. 
The exact time of dosing will be decided based on logistics and will be documented in 
the source. 
Part 2 
Subjects will receive a single oral dose of [14q-KD025 in the fed state on one dosing 
occasion. 240 mL of water will be given immediately following oral administration. 
The exact time of dosing will be decided based on logistics and will be documented in 
the source. 
11.1 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 tablet/capsule has 
been swallowed. 
Part 1 only: The IV dose will be administered by trained staff to ensure dosing 
compliance. 
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. 
11.2 	
Prior and Concomitant Medications 
No medication will be permitted from 14 days before IMP administration until the 
follow-up call except 4 g of paracetamol per day 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.

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 (ADR) 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 after the final follow-up 
call. 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

Sponsor/Quotient Sciences Confidential 
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, 
etc) 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 at the follow-up call. 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.

Serious Adverse Events 
14.4.1 	
Definition of Serious Adverse Events 
A 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 reported to the sponsor. 
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 IB) and serious. SUSARs are subject to expedited 
reporting to the MHRA, 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. Urine and faecal samples 
will be analysed for total radioactivity. 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

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.

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.

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 (QA) 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. 
19 Quality Control and Quality Assurance 
Quality control (QC) of all data collected from this study will be performed in accordance 
with Quotient SOPs. This study (or elements thereof) may be subject to QA audit, in line 
with current internal auditing procedures. Similarly, the study (or elements thereof) may 
be subject to sponsor QA audit.

19.1 	
Monitoring 
GCP requires that studies are adequately monitored. The sponsor should determine the 
appropriate extent and nature of monitoring. A study monitor, independent of Quotient 
Sciences, will be appointed to verify that the study is conducted in accordance with 
current GCP, regulatory requirements, the protocol and that the data are authentic, 
accurate and complete. 
The investigator agrees to receive visits from a study monitor and provide assistance to 
verify protocol implementation, source completion and transcription of data into the 
electronic case report form, document storage and AE reporting. 
Quotient Sciences will extend the professional privilege of access to the subjects' clinical 
source documents to the study monitor, EC, regulatory bodies or other authorised 
personnel (eg auditor) for the purposes of source data verification. 
Following completion of the study both study related documents and subject data may 
be sent to the sponsor at a location outside of the UK where data protection laws differ. 
In the interests of confidentiality, subjects will not be identified on any such documents 
or data, and specific subject consent for such a disposition will be obtained. 
20 Finance and Insurance 
The sponsor (Kadmon Corporation LLC) has funded this study. A no-fault clinical trials 
insurance has been obtained by the sponsor. The sponsor insurance will compensate 
subjects in accordance with the Association of the British Pharmaceutical Industry 
Guidelines for Phase I Clinical Trials 2018 edition [15].

°Subjects who participated in Part 1 will be admitted to the clinical unit after a minimum washout period of 7 days. 
Discharge from clinical unit. Subjects may be discharged as a group 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 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 by up to a maximum of 2 additional 24 h periods (up to 216 h 
post-dose, Day 10) for further collection of urine and faeces. If the criteria are not 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 follow-up phone call will take place 5 to 7 days after discharge or after the end of the last collection period.

3 Introduction 
This document details the following for Quotient Sciences (Quotient) Study QSC200323 
(KDO25-108): 
• criteria to be used for the definition of the analysis populations relating to safety, 
pharmacokinetic (PK) and mass balance data 
• handling of missing data 
• proposed tables, figures and listings (TFLs) for demographic, dosing, PK, mass balance 
and safety data 
• methods for 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 17 Jan 2019 and 
non-substantial amendment NSA01 dated 18 Apr 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, PK 
parameter estimation and output, mass balance parameter estimation and output, and safety 
output; including all summary TFLs; and the clinical study report (CSR). 
Quotient will provide two sets of TFLs during the study: 
• post database lock TFLs (draft) for Kadmon Corporation LLC (Kadmon) 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 Subjects Definitions 
During the clinical phase of the study, an evaluable subject is defined: 
• for Part 1, as a subject who has sufficient data for evaluation of the primary 
bioavailability objective of the study 
• for Part 2, as a subject who has provided biological samples for up to 168 h after drug 
administration or has demonstrated >90% mass balance recovery, or has <1% of the 
administered dose eliminated in excreta for two consecutive days, whichever is the 
sooner 
These definitions of an evaluable subject will not be used during the reporting phase including 
the identification of analysis populations and datasets. 
All enrolled subjects are defined as those subjects who signed the informed consent, qualified 
per the inclusion/exclusion criteria and were allocated a subject number.

Study Design 
5.1 	
Brief Description 
This is a single centre, non-randomised, open-label, two-part study in 6 healthy male subjects. 
Subjects must have participated in Part 1 in order to be eligible for Part 2. An overview of the 
study is presented in Figure 1 and assessment time points are detailed in Appendix 1 for Part 1 
and in Appendix 2 for Part 2. 
5.1.1 	
Study Plan Part 1 
Part 1 is an open-label, non-randomised single oral dose (tablet) followed by an IV microtracer 
assessment. 
On Day 1, subjects will receive a single dose of KD025 (Treatment A) 30 min after the start of 
a standard breakfast. Subjects will then receive an IV dose of [14q-KD025 (100 pg, a 
imicrodose) containing not more than (NMT) 37 kBq (1000 nCi) [14C], as a 15 min IV infusion 
(Treatment B), starting 1.75 h after the oral dose administration (Treatment A) ie, starting 
15 min before the expected Tmax (2 h) for the oral dose. Subjects will remain resident in the 
clinic until up to 48 h post-oral dose (ie up to Day 3).

5.1.2 Study Plan Part 2 
Part 2 is an open-label, non-randomised absorption, distribution, metabolism, excretion 
(ADME) assessment. 
Following a minimum washout period of 7 days, subjects who participated in Part 1 of the 
study will be admitted to the clinical unit for participation in Part 2 of the study (on Day -1). On 
the morning of Day 1, each subject will receive a single oral administration of 200 mg 
[14q-KD025 capsule containing (NMT 9.8 MBq) (215 pCi) [14C] (Treatment C) 30 min after the 
start of a standard breakfast. 
Subjects will remain resident in the clinic 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, the 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 216 h 
post-dose (Day 10). During the additional residency period only urine and/or faeces will be 
collected. 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. To ensure ongoing wellbeing of the 
subjects, a follow-up phone call will take place 5 to 7 days post-discharge from the study or 
after the end of the last collection period.

achieving the release criteria may be extended up to a maximum of 216 h post-dose (Day 10). During the additional 
residency period only urine and/or faeces will be collected. 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. 
5.2 	
Study Sample Size 
No sample size calculation was performed. For a study of this type, a sample size of 6 
subjects, to ensure data in 4 evaluable subjects (as defined in Section 3.2.1) is considered 
appropriate to meet the objectives of the study. 
5.3 	
Subject Numbers (including Replacement Subjects) 
This is an open-label, non-randomised study and therefore a randomisation schedule will not 
be produced. 
Subject numbers will be allocated on the morning of dosing in Part 1 according to the code 
001 to 006 using the lowest number available. 
No replacement subjects are to be used in this study. 
5.4 Blinding Issues 
This is an open-label, non-randomised study and therefore blinding is not required.

Populations for Analysis 
6.1 	
Safety Population 
The safety population will include all subjects who have received at least 1 dose of IMP via 
either oral administration or IV administration within the study. 
The safety population will be confirmed by Quotient with approval from Kadmon after database 
lock and will be used for the analysis of demographic and baseline characteristics, and all 
safety data. 
6.2 Pharmacokinetic Population 
The PK population will include all subjects who have received at least 1 dose of IMP and who 
satisfy the following criteria for at least 1 profile in either Part 1 or Part 2: 
• no missing samples or invalid post-dose analytical results at critical time points (eg 
around the Cmax) 
• no relevant protocol deviations which may impact the study objectives with respect to the 
PK endpoints 
• no relevant AEs such as vomiting (after oral dosing) or infusion site reaction (after IV 
dosing) which suggest that the whole dose was not available for absorption/delivery for a 
particular subject 
In the event that quantifiable pre-dose concentrations greater than 5% of Cmax are observed, 
requirements for further action will be agreed with Kadmon and documented at the same time 
as the PK population and any corresponding dataset(s). 
The PK population will be confirmed by Quotient with approval from Kadmon following 
derivation of all PK parameter estimates. 
If required, a PK analysis dataset or datasets may also be documented by Quotient with 
approval from Kadmon at the same time as the PK population. The PK analysis dataset(s) will 
be a subset of the PK population. 
All enrolled subjects will be used for the PK data listings and the PK population will be used 
for the provision of PK tables and figures. The PK analysis dataset(s) may be used instead of 
the PK population for generation of PK tables and figures or to generate additional PK tables 
and figures. Where possible, this decision will be documented at the same time as the PK 
population and PK analysis dataset(s). 
6.3 Mass Balance Population 
The mass balance population will be defined for Part 2 and will include all subjects who have 
received 1 dose of IMP in Part 2 and who have evaluable total radioactivity concentration 
(urinary and/or faecal) data and who have no protocol deviations that may affect the mass 
balance analysis. Such protocol deviations would include anything that affects the accurate 
measurement of the 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

Sponsor/Quotient Sciences Confidential 
The mass balance population will be confirmed by Quotient with approval from Kadmon once 
all urinary and faecal data have been received. 
If required, a mass balance analysis dataset or datasets may also be documented by Quotient 
with approval from Kadmon at the same time as the mass balance population. The mass 
balance analysis dataset(s) will be a subset of the mass balance population. 
All enrolled subjects will be used for the mass balance data listings. The mass balance 
population will be used for the analysis of the mass balance concentration data and the 
provision of mass balance tables and figures. The mass balance analysis dataset(s) may be 
used instead of the mass balance population for generation of mass balance tables and figures 
or to generate additional mass balance tables and figures. Where possible, this decision will 
be documented at the same time as the mass balance population and mass balance analysis 
dataset(s). 
7 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 
subjects and summaries of all other data described in this section will be based on the safety 
population, unless otherwise stated. 
7.1 Screening Failures 
Data for subjects who have failed screening will be databased but will not be subjected to data 
cleaning and therefore will not be reported, ie will not be included in the STDM or ADaM 
datasets, or any of the TFLs or the CSR. 
7.2 Subject Disposition and Withdrawals 
The number and percentage of subjects enrolled, dosed (in Part 1 and Part 2 separately), 
completed and discontinued will be presented overall. If any subjects discontinued from the 
study early then the number of subjects for each reason for discontinuation will be presented 
overall. 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 single summary table will be produced detailing the number and percentage of subjects in 
each population for each study part (for safety and PK populations) and overall (for safety, PK 
and mass balance populations). The reasons for exclusion from each population will also be 
included in the summary. 
Details of subjects included and excluded in the different analysis populations will be listed. 
7.4 Analysis Datasets 
If applicable, a summary table per population will be produced detailing the number and 
percentage of subjects in each analysis dataset for each study part and overall, as required. 
The table will be based on the relevant population the dataset is a subset of (ie the PK or mass

balance population). The reasons for exclusion from each dataset will also be included in the 
summary. 
Details of subjects included and excluded in the different analysis datasets 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. Note: Weight is also recorded at admission 
to Part 2, this data will be listed but not summarised (see Section 10.7). Age will be calculated 
using the following formula: 
Age (years) = 
Date of first dose of IMP — date of birth  
365.25 
and will be rounded down to the nearest year (using the SAS Software floor function). If any 
subjects are enrolled but not dosed and had other assessments recorded, age will be 
calculated using the date of informed consent. 
Summary statistics (number of subjects with an observation [n], mean, standard deviation 
[SD], median, minimum and maximum) will be presented overall for age at first dose and for 
height, weight and BMI at screening. The number and percentage of subjects will be presented 
overall for race, ethnicity and sex. The denominator for the percentage is all subjects in the 
safety population. 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 use nicotine 
replacement products?] and alcohol consumption) will be summarised overall as a categorical 
variable. 
Demographic and lifestyle data for all subjects will be listed. 
7.6 Medical/Surgical History 
Medical/surgical history will be recorded for each subject at the screening visit and updated at 
admission to each study part. All medical/surgical history data will be listed by subject. 
7.7 	
Prior and Concomitant Medication 
Medications (drug name) will be coded using the World Health Organisation (WHO) Drug 
Dictionary Global Drug Reference (2019 Q1 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 name and code) 
• chemical subgroup (ATC 4th level name and code) 
Prior medications are defined as medications that starts and stop prior to the first dose of IMP. 
All other medications will be defined as concomitant medications including those that start 
prior to the first dose of IMP 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.

All medications, including coded terms, 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 IMP 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) for each part (as appropriate) will be listed by subject for all subjects: 
• carbon monoxide breath test 
• urine drug screen 
• alcohol breath test 
• virology (screening only) 
• creatinine clearance (screening only)

9.1.2 Rules for Pharmacokinetic Parameter Estimation 
For Part 1, PK parameters for Treatment B will be calculated using times relative to the start 
of infusion. For Treatment A (Part 1) and Treatment C (Part 2), PK parameters will be 
calculated using times relative to the administration time of Treatment A and C, respectively. 
The imputation of non-numerical or negative values reported in the input dataset will be 
performed as follows: 
• pre-dose sample times will be entered as zero 
• values that are below the limit of quantification (BLQ) obtained prior to the Cmax will be 
entered as zero 
• values that are BLQ after the Cmax will be treated as missing 
• should partial AUCs be required, then values that are BLQ 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 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

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 [14g-contribution exceeds 1% 
of the dose administered. If required, KD025, KDO25m1 and KD025m2 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. 
Absolute Bioavailability of KD025 (F) will be calculated for individual subjects where possible 
as follows: 
F = A 
t 	
AU
C 	
or Cmax (KDO25 oral) 	
Dose(IV) 
UC or Cmax ([14C] — KD025 IV) x Dose(oral)  x 100 
 
F will be calculated using Cmax and AUC(0-inf). If for any reason the AUC(0-inf) is not 
calculable (NC), then an alternative or additional AUC such as AUC(0-last) or an AUC over a 
partial area may be used to calculate F. 
The following comparisons will be made: 
• absolute bioavailability tablet (Treatment A vs Treatment B) 
• absolute bioavailability capsule (Treatment C vs Treatment B) 
Non-dose-corrected relative bioavailability (Frel) will be calculated for individual subjects 
where possible as follows:

Fret will be calculated using Cmax and AUC(0-inf). If for any reason the AUC(0-inf) is not 
calculable then an alternative or additional AUC such as AUC(0-last) over a partial area may 
be used to calculate Frei. 
The following comparisons will be made, where tablet dosing [Treatment A] is considered the 
reference): 
• relative bioavailability capsule versus tablet (Treatment C vs Treatment A) 
In Part 2, metabolite to parent ratios (MPR) will be calculated as follows using AUC(0-inf) and 
Cmax. If for any reason the AUC(0-inf) is not calculable then an alternative or additional AUC 
such as AUC(0-last) may be used:

Correcting for molecular weight (MW): 
• KD025 MW = 452.52 g/mole 
• KDO25m1 MW= 410.44 g/mole 
• KD025m2 MW =411.42 g/mole 
In addition, for Part 2, total radioactivity whole blood to plasma ratios will be determined 
using SAS by the Lead Statistical Programmer (or designee) at the time points defined in the 
protocol for whole blood total radioactivity sampling. If the blood and/or plasma concentration 
values are BLQ (ie less than the lower limit of quantification [LLOQ]) at any given time point, 
then the ratio will not be calculated. 
When converting whole 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 whole 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)

For Part 2, Pharmaron will provide the following concentration and weight data on a per subject 
basis for each collection interval as specified in the clinical protocol: 
• total radioactivity concentration (mass unit equivalents/g) for each of urine and faeces 
• 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.

9.3.2 Rules for Mass Balance Parameter Estimation 
The following will be calculated for total radioactivity in urine, faeces and urine and faeces 
combined (ie total) 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 interval 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 interval 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 intervals (where matrix is either urine or faeces). The 
amount excreted in the pre-dose sample should not be included in the calculation of the 
cumulative amount excreted. 
• the cumulative amount excreted in urine and faeces combined, ie CumAe(total), will be 
calculated across all collection intervals using the following formula: 
CumAe(total) = CumAe(urine) + CumAe(faeces) 
• the % recovery of the total radioactive dose 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 interval using the following formula (where matrix is either urine or faeces): 
%Ae(<matrix>) = 100 * Ae(<matrix>) / Total Radioactive Dose Administered 
• the % recovery of the total radioactive dose in urine and faeces combined, ie %Ae(total), 
will be calculated for each collection interval 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 intervals (where matrix is either urine or faeces). The 
% amount of the total radioactive dose excreted in the pre-dose sample should not be 
included in the calculation of the cumulative % of dose excreted. 
• the cumulative % amount of the total radioactive dose excreted in urine and faeces 
combined, ie Cum%Ae(total), will be calculated for each collection interval using the 
following formula: 
Cum%Ae(total) = Cum%Ae(urine) + Cum%Ae(faeces)

For urine and faeces, where a subject has failed to void over a particular collection interval the 
amount excreted (Ae) will be set to zero. 
If part of a void over a particular collection interval is missing due to spillage or accidental 
discarding, the Ae will still be calculated providing other samples have been 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. 
Imputation of non-numerical values reported in the urine and faecal dataset (ie concentrations 
that are BLQ) will be entered as zero for calculation of 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 if considered necessary. The 
results will be reported for each subject as a single value for the whole collection period and 
included in the calculation of overall cumulative excretion and recovery parameters.

• 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 cumulative excretion (CumAe) and cumulative recovery (Cum%Ae) by 
collection period and 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 
intervals (eg collection to 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 
parameters (ie CumAe and Cum%Ae), where the last observed value will be carried forward 
to the subsequent time point. 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. 
9.4.2 Mass Balance Figures 
Mass balance figures will be presented for the mass balance population. 
Arithmetic mean cumulative excretion (ie CumAe) and cumulative recovery (ie Cum(Y0Ae) vs 
time curves will be produced on a linear/linear scale and will include ± SD bars. This means 
there will be 2 plots: 
• one plot with CumAe(urine), CumAe(faeces) and CumAe(total) for total radioactivity in 
plasma overlaid 
• a separate plot with Cum%Ae(urine), CumlY0Ae(faeces) and Cum%Ae(total) for total 
radioactivity in plasma overlaid 
A legend identifying each profile (ie urine, faeces and total) will be displayed on the mean 
plots. Figures will be produced using the LOCF imputation strategy (see Section 9.4.1) if 
summary tables are produced for this method. 
9.4.3 Mass Balance Listings 
The sample collection data (eg collection intervals) for all urine and faecal samples will be 
listed. In addition, all total radioactivity concentrations, urine and faecal weights and all mass 
balance parameters will be listed on a per subject basis. 
9.4.4 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.

The safety population will be used for all safety data summaries. 
Separate summary tables and listings will be produced for each study part, unless otherwise 
specified. Screening data for ECGs and vital signs will be listed only once, under Part 1 listings. 
For Part 1, safety data and related summaries will be based on the combination of both 
regimens associated with the study part, rather than being presented in relation to a specific 
treatment, unless otherwise specified. 
10.1 Extent of Exposure and Treatment Compliance 
In Part 1, the dose of Treatment B, including the dose of radioactivity (in kBq), will be

In Part 2, the dose of Treatment C, including the dose of radioactivity (in MBq and pCi), will 
be summarised (ie, n, mean, SD, median, minimum and maximum). 
Dosing details (including the date and time of all doses administered) will be listed for all 
subjects. Any recorded deviations from the planned dosing regimen will be listed as protocol 
deviations. 
10.2 	
Meal Details 
Meal details as recorded in the database 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 study database. 
For Part 1, AEs will be assigned to the combination of both regimens associated with the study 
part and not assigned to a specific treatment. 
Adverse events will be coded using the Medical Dictionary for Regulatory Activities (MedDRA 
v22.0), and reported by System Organ Class (SOC) and Preferred Term (PT). 
Adverse events will be classified into the following categories: 
• pre-dose AEs: AEs recorded at screening or with a start date and time prior to the first 
dose of IMP 
• treatment-emergent adverse events (TEAEs): AEs that commence during/after the first 
dose of IMP or commence before first dose of IMP (ie a pre-dose AE or existing medical 
condition) but worsen in intensity during exposure to IMP. 
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. 
TEAEs will be assigned to the study part in which the AE first occurred. Where the severity of 
an AE intensifies or symptoms change in a subsequent study part, this will be defined as a 
new AE and included under the treatment(s) associated with the subsequent study part. 
Adverse events that occur during the washout period will be assigned to the study part 
[treatment(s)] the subject received during the period immediately before the washout period. 
Adverse events will be classified as "unrelated", "possibly related" and "related" when 
considering their relationship to IMP. TEAEs classified as "possibly related" and "related" will 
be defined as adverse drug reactions (ADRs). An ADR is any AE where a causal relationship 
with the IMP is at least reasonable possibility (ie "possibly related" and "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 IMP of a TEAE is missing, the severity/relationship will be 
tabulated as "missing" in the summary tables. 
Where the start date of an AE is missing and the stop date is on or after the day of first dose 
of IMP 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. The study part to 
which the AE will be assigned will be programmatically assigned in SAS. 
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 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, with the exception of TEAEs by severity and 
relationship to IMP, the number of subjects and the number of events will be summarised. For 
summaries by severity and relationship only the number of subjects will be summarised. 
For counts of subjects experiencing events the following will apply: 
• a subject experiencing TEAEs in more than one body system, within a study part, will be 
counted once in the total number of subjects with TEAEs in that study part 
• a subject with more than 1 TEAE in the same SOC, within a study part, counts only once 
at the SOC level; 
• a subject with more than 1 TEAE in the same PT, within a study part, counts only once at 
the PT level. 
For event counts, all events are included. 
When it is necessary to calculate percentages, the denominator will be the total number of 
subjects in the safety population for that study part and the numerator will be the total number 
of subjects reporting a TEAE within the relevant category. 
Summaries presented for SOC and PT will be presented in descending order of frequency 
overall (le most frequently reported SOC in the study part and then by most frequently reported 
PT in the study part within each SOC). 
10.3.1.1 	
Overall Summary of Adverse Events 
The following will be summarised for the safety population by study part: 
• number and percentage of subjects reporting at least one TEAE 
• number and percentage of subjects reporting ADRs 
• number and percentage of subjects reporting severe TEAEs 
• number and percentage of subjects reporting serious TEAEs 
• number and percentage of subjects reporting TEAEs leading to subject withdrawal 
• number and percentage of subjects reporting TEAEs leading to death 
• total number of TEAEs 
• total number of ADRs 
• total number of severe TEAEs 
• total number of serious TEAEs 
• total number of TEAEs leading to subject withdrawal

10.6 ECGs 
The details of measurement of supine ECG parameters (ie ventricular rate, QT interval, QTcF 
interval, PR interval, QRS duration, QRS axis and interpretation) are described in the study 
protocol. ECG parameters will be reported in the order given above in both summary tables 
and data listings. 
10.6.1 Summary Tables for ECGs 
ECG data, including change from baseline (Day 1, Pre-dose for each study part), will be 
summarised (ie n, mean, SD, median, minimum and maximum) at each post-baseline time 
point by study part.The number and percentage of subjects with normal and prolonged QT 
intervals corrected for heart rate using Fridericia's correction (ie QTcF) and increases in QTcF 
intervals from baseline within the categories defined in Table 5 (based on the International 
Council on Harmonisation [ICH] E14 guideline [1]) will be summarised by time point within 
each study part. Percentages will be based on the number of subjects with measurements at 
the relevant time point. 
For 'Overall' counts the worst (highest) value for each subject will be used for the counts. For 
the parameter 'Increase in QTcF interval from baseline', decreases in QTcF value fall into the 
<30 category (ie every subject should appear once in this summary table and actual change 
rather than absolute change is used for this parameter).

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 the 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: 
geometric SD = expiSDflog(raw data)]) 
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%: 
geometric CV% = 100 x (expfSD[log(raw data)])2-1)2/2 
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 7 below, unless otherwise 
stated:

Note: The above table relates to rounding of summary stats from data received to certain 
number of decimal places. Summary stats on data received to a certain number of significant 
figures will be presented to the same number of significant figures as the data. 
Details of how the PK parameters will be presented are detailed in Section 9.1.1. 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 (as defined in Section 3.2.1). Details of 
age and sex will be included on all data listings.

If any nominal 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 PK parameter 
estimation using WinNonlin is described in Section 9.1.2 and for mass balance parameter 
estimation using SAS Software is described in Section 9.3.2. Imputations for reporting PK are 
described in Section 9.2.1. 
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 
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 presented by study part only (ie no time points), all summary statistics will be 
QC'd 
• for tables presented by study part and time point, 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 study part and time point as appropriate, will be QC'd 
• for AEs, the study part/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 QC check against the study database 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 SAS datasets used for analysis and reporting will be transferred to Kadmon on issue of the 
final CSR. This will be performed in compliance with CDISC ADaM (IG v1.1), data will be 
transferred as SAS Software transport files and will include define.xml (v2.0) output as well as 
a Data Reviewers Guide in pdf, which will be linked to the ADaM define.xml. 
In addition, KDO25m1 and KD025m2 Part 1 data provided by Covance will not be reported or 
analysed but will be transferred to Kadmon as raw data and will be included in the SDTM 
datasets 
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 
• US letter size (8.5 x 11 inches) 
Tables and listings will be produced as MS Word 2016 documents and figures will be produced 
as PDF files. Listings will be sorted by subject ID number and treatment (where applicable). 
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 Subjects who participated in Part 1 will be admitted to the clinical unit after a minimum washout period of 7 days. 
h Discharge from clinical unit. Subjects may be discharged as a group 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 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 by up to a maximum of 2 additional 24 h periods (up to 216 h 
post-dose, Day 10) for further collection of urine and faeces. If the criteria are not 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. 
9 A follow-up phone call will take place 5 to 7 days after discharge or after the end of the last collection period. 
d Targeted (symptom driven) physical examination 
e Haematology and clinical chemistry at each time point. 
f Blood pressure, heart rate and oral temperature will be measured at each time point 
9A single urine sample will be collected at pre-dose (the first void of the day) and then during the following collection periods 0-6, 6-12, 12-24 h post-dose and then 
daily (24 h collections) until Day 8/Discharge. 
h Faeces will be collected from admission until pre-dose and then daily (24 h collections) until Day 8/Discharge.
