non-infectious uveitis when administered as a single intravitreal injection of 0.3 µg, 0.6 µg and 
1.2 µg with the option of an addition cohort with a dose of 2.1 µg PP-001 
Secondary Objectives 
• To assess the improvement of inflammation in patients with chronic, non-infectious uveitis 
after ascending doses of PP-001 when administered as a single intravitreal injection of 0.3 µg, 
0.6 µg and 1.2 µg with the option of an addition cohort with a dose of 2.1 µg PP-001 
• To evaluate the pharmacokinetics of PP-001 in patients with chronic, non-infectious uveitis 
when administered as a single intravitreal injection of 0.3 µg, 0.6 µg and 1.2 µg with the option 
of an addition cohort with a dose of 2.1 µg PP-001 
Study Population: 
Inclusion Criteria 
1. Male or female patients without childbearing potential older than 18 years of age who have 
diagnosis of chronic posterior uveitis, intermediate uveitis or panuveitis. 
2. Good general state of health (mentally and physically). Laboratory parameters and vital 
signs of patients must be within the normal ranges and patients must not have a diagnosis 
of any acute or chronic illness except uveitis. 
3. A signed and dated written informed consent form. 
4. A signed and dated written data protection consent form. 
5. Male patients must ensure that one highly effective method combined with an acceptable

22. Patients with diagnosis of any acute or chronic systemic illness other than uveitis  
Duration of Study: Total duration of study for each patient will be 8 weeks or less (from 
screening to last follow-up). 
Drug Products: PP-001 will be supplied as a sterile concentrate solution in a 2 ml vial and will 
be diluted according to dose as specified in the pharmacy manual. 
Study Drug Assignment: Patients will be dosed in ascending order with 0.3, 0.6, 1.2 or 2.1 µg 
PP-001 depending on the cohort to which they are assigned. 
Duration of Treatment: Patients will receive a single dose of PP-001. 
Study Drug Administration: PP-001 will be administered as a single intravitreal injection, 
which will be performed under sterile conditions in an operating room setting. For safety reasons 
an emergency pars plana vitrectomy aiming at removal of injected drug will be available in case 
of a severe adverse event including, but not limited to, acute loss of visual acuity or acute 
inflammatory or toxic response to injection. It is therefore mandatory for patients to remain in 
the hospital for at least 4 hours after the injection procedure.  
Blinding: This is an open-label study. 
Study Design: This prospective, multi-centre, open-label, non-randomized, consecutive study 
will be conducted in accordance with the European Union (EU) Clinical Trial Directive 
2001/20/EC and 2005/28/EC, The Medicines for Human Use (Clinical Trials) Regulations 2004 
and current amendments, the Declaration of Helsinki (revised version of Edinburgh, Scotland 
2000), Good Manufacturing Practice (GMP), Good Clinical Practice (GCP) and the current 
national regulations and guidelines, approved by both the local ethics committee and regulatory 
authority. Eighteen patients older than 18 years of age will be enrolled and receive a single 
intravitreal injection of PP-001. Patients must have chronic, posterior uveitis, intermediate 
uveitis or panuveitis requiring treatment and have been receiving an adequate therapy of e.g. 
systemic corticosteroid treatment or immunosuppressive therapy (e.g. azathioprine, 
methotrexate, cyclosporine, mycophenolate, tacrolimus) or any combination thereof. Any 
systemic therapy at study start should be continued throughout the study. Patients must have 
best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity of 10 letters

or better (approximately 1/35 or 0.032) but equal or less than 50 letters (approximately 20/100 or 
0.2) in the study eye.  
The study will involve eight inpatient visits (Screening, Baseline, the day of injection [Day 0] 
and Days 2, 7, 14, 21 and 28) and telephone calls on Day 1 and on Day 40. 
Patients will be divided into three cohorts of four patients. Patients will receive the following 
treatments administered as a single intravitreal injection: 
• Cohort 1 will receive 0.3 µg of PP-001 
• Cohort 2 will receive 0.6 µg of PP-001 
• Cohort 3 will receive 1.2 µg of PP-001 
The patients within a cohort will be dosed consecutively with a minimum time interval of 7 days 
between the start of injection of the previous patient and start of injection of the next patient. The 
results from each dosing day will be reviewed before progressing with the subsequent dosing 
day. The next cohort will only commence with dosing after the previous cohort has completed all 
study sessions up to Day 28 and no safety issues have been identified after being reviewed by the 
safety data management board (SDMB).  
After 12 patients have been treated in the three cohorts and after all patients have finished the 
last follow up an interim analysis by the SDMB will be conducted to identify potential safety 
issues and to determine the highest tolerable dose. If no safety issue can be identified, then a 
fourth, higher dose will be given to a cohort of four patients (Cohort 4). The dose for a potential 
Cohort 4 will be 2.1 µg of PP-001. 
If safety issues are identified in any of Cohorts 2, 3 or 4, two additional patients will receive the 
next lower dose. 
Statistical Considerations: 
• Sample Size: Eighteen patients will be enrolled in the study. No power calculations will be 
performed and the sample size is based on the requirements of the study design.  
• Treatment Comparison of Interest: a comparison will be made between the cohorts with 
regard to safety tolerability and efficacy. 
Interim Analysis: the results from each dosing day of the first cohort will be reviewed before 
progressing with the subsequent dosing day. Dosing of the next cohort will only commence after 
the previous cohort has completed all study sessions up to Day 28 and no safety issues have been 
identified after being reviewed by the SDMB. 
Analysis Populations 
• Intent-to-treat (ITT) Analysis Set: all patients regardless of whether or not the patient 
received study drug 
• Per-protocol Analysis Set: all ITT Analysis Set patients who have no major protocol 
deviations, and who complete the study up to the end of the post-study assessments 
• Safety Analysis Set: all patients who receive any amount of study drug. All safety analyses 
will be conducted in this population

Confidential Information 
• Pharmacokinetic Analysis Set: all patients who receive any amount of study drug will be 
included in the formal analysis of pharmacokinetic parameters providing they have at least 
one evaluable pharmacokinetic sample 
Variables for Analysis: 
Primary 
• Safety parameters (i.e., changes in clinical signs and symptoms from ophthalmic exam, and 
AEs) 
Secondary 
• Improvement of inflammation or of any other parameter determined at the ophthalmic 
examination following the injection of PP-001 
• The concentration of PP-001 in plasma at Screening, 4 h ± 1 h after dosing and on Day 2 
Safety analysis 
The incidence of treatment-emergent adverse events (TEAEs), SAEs, deaths and 
discontinuations of study drug due to an AE or SAE will be summarized by System Organ Class 
and Preferred Term according to the Medical Dictionary for Regulatory Activities, by 
relationship to study drug, and by severity. The incidence of potentially clinically significant 
vital signs will be summarized. 
Pharmacokinetic analysis 
The concentration of PP-001 in plasma will be measured in blood samples taken at Screening, 
4 h ± 1 h after dosing and on Day 2.

INTRODUCTION 
 
Background of the Disease and Treatment Options 
PP-001 is indicated for the treatment of non-infectious uveitis (NIU). Uveitis is a chronic or 
relapsing intra-ocular inflammatory disease that affects the uvea (composed of the iris, choroid 
and ciliary body), retina, vitreous body, optic nerve head, retinal pigment epithelium and the 
anterior chamber, but may also involve adjacent structures, including the sclera or cornea 
[Barisani-Asenbauer et al., 2012; Barry et al., 2014]. 
The integrity and transparency of the ocular media (aqueous, lens and vitreous) and ocular tissue 
(iris, ciliary body, retina, pigment epithelium and choroid) are critical for optimal visual function 
because they refract, transmit, regulate and sense light. Any distortion of the visual axis by 
inflammatory processes within the eye can adversely affect vision [Caspi, 2008]. Uveitis is a 
disease with symptoms ranging from temporary effects, including discomfort, pain or blurring of 
vision, to permanent defects in visual acuity and visual field due to irreversible tissue damage 
and even blindness. Visual impairment may result from direct damage to any ocular structure 
(e.g., cataracts, glaucoma, macular oedema [Barry et al., 2014]). 
Uveitis can be caused by infections or by autoimmune disease. Non-infectious uveitis covers all 
uveitis cases, which are considered to be of autoimmune or autoinflammatory origin including 
systemic immunological disease-associated uveitis. It also includes acute and chronic uveitis, as 
well as relapsing forms, and may occur at any location in the eye. 
In NIU, T-cells (Th1 and Th17) become autoreactive towards ocular antigens like retinal-soluble 
antigen or interphotoreceptor retinoid-binding protein and this leads to a substantial immune 
response. Once activated, T helper cells secrete many different cytokines, of which interferon 
gamma (IFN-γ) and interleukin 17 (IL-17) are the hallmarks of Th1 and Th17 cells, respectively. 
This results in the recruitment of neutrophils and other leukocytes as well as lymphocytes from 
the peripheral blood to the eye. Subsequent tissue destruction is mediated by non-specific 
activation of immune cells.  
The main treatment strategies for NIU involve the suppression of local inflammation. Treatments 
range from topical therapy (commonly corticosteroid eye drops) to systemic immunosuppression 
with either corticosteroids or steroid-sparing immunomodulatory therapeutic agents [Barry et al., 
2014]. Topical medication is generally only used to treat uveitis that affects the anterior part of 
the eye (i.e. anterior chamber). Patients suffering from intermediate and/or posterior uveitis (i.e. 
that which affects the vitreous body and retina/choroid) are routinely treated with high doses of 
systemic corticosteroids. Dosing of corticosteroids depends on the timeframe and severity of 
inflammation. Usually, the initial treatment includes high-dose corticosteroids, which is then 
slowly tapered according to disease activity. The ultimate expected therapeutic role of PP-001 
will be as a steroid-sparing agent and allow steroid doses to be tapered quickly. Due to its 
underlying mode of action, PP-001 is suitable for the treatment of NIU only. 
 
Background on PP-001 
PP-001 has the molecular formula C19H8F7NO4S and a molecular weight of 479.3 g/mol. PP-001 
is a third generation small molecule inhibitor of dihydroorotate dehydrogenase (DHODH) and 
has a half-maximal inhibitory concentration (IC50) of DHODH of less than 4 nM. By inhibiting

Version 3.1_GER 03 November 2017  
Page 18 of 54 
Confidential Information 
DHODH, the expression of IL-17 and IFN-γ is suppressed. Independently, highly proliferating T 
cells are inhibited. PP-001 thereby specifically targets the underlying cause of uveitis. 
PP-001 is 150-fold more potent than the orally administered small-molecule DHOHD inhibitor, 
leflunomide (IC50 DHODH, 650 nM). Leflunomide (Arava®) and its active metabolite 
teroflunomide (Aubagio®) are approved for the treatment of rheumatoid arthritis and multiple 
sclerosis, respectively. PP-001 is structurally and mechanistically distinct from leflunomide. The 
hepatic metabolization of leflunomide to teriflunomide leads to the off-target inhibition of 
protein kinases and is responsible for its side effect profile [Herrmann et al., 2000]. 
PP-001 drug substance is a small, synthetic molecule. The drug product is formulated as 1 mg/ml 
sterile concentrate formulation in 2 ml glass vials (PP-001 concentrate for intravitreal injection). 
Buffer and tonicity agents are added as excipients. Prior to administration, the PP-001 
concentrate solution is diluted with sterile aqueous sucrose solution to the final dosing solution 
(PP-001 solution for intravitreal injection). 
 
Non-Clinical Development 
1.3.1 Mechanism of Action and Non-Clinical Pharmacology 
Proof of concept for PP-001 in the treatment of non-infectious uveitis was established in a rat 
experimental autoimmune uveitis (EAU) model following oral and intravitreal administration of 
PP-001. In these studies, PP-001 was shown to be effective in prevention and treatment of 
experimentally induced autoimmune uveitis. Treatment with PP-001 at an oral dose level of 
25 mg/kg significantly reduced the number of relapses and their intensity when compared to 
control. The determined ocular exposures (AUC) at the oral efficacious dose level of 25 mg/kg in 
rat were 1.27 µg·h/g and 4.8 µg·h/g for vitreous and retina, respectively. Intravitreally dosed 
PP-001 (3 µg/eye) reduced the number of relapses per eye by 50% when compared to control. 
Inhibition of the human ether-à-go-go-related gene (hERG) channel by PP-001 was not indicated 
when tested at concentrations well above the intended human exposure. The 14-day intravenous 
repeated dose toxicity study in rats did not show evidence for adverse effects on safety 
pharmacology parameter at the highest dose tested (1 mg/kg body weight). PP-001 is intended 
for intravitreal use with no need of systemic availability of the drug. The systemic exposure in 
humans is expected to be below the minimal biologically active concentration of 958 ng/ml for 
T-cells and 58–265 ng/ml for evaluated cytokines. Thus, no stand-alone in vivo safety 
pharmacology studies were conducted.  
1.3.2 Pharmacokinetics and Product Metabolism 
Pharmacokinetic and metabolic parameters have been evaluated in several in vitro and in vivo 
experiments in various species.  
PP-001 exhibited strong in vitro plasma protein binding properties with bound fraction levels of 
>99.9%. PP-001 exhibited high metabolic stability after incubation with human liver 
microsomes. Inhibition potential towards human Cytochrome P450 enzymes was detected but 
considered insignificant due to low systemic PP-001 exposure after intravitreal administration.

Clinical Protocol PP-001-1001 
Version 3.1_GER 03 November 2017  
Page 19 of 54 
Confidential Information 
Following intravitreal administration of 60 to 250 µg PP-001 per animal, systemic exposure in 
the low ng/ml range was detected. Systemic exposure at efficacious human doses (0.6–1 µg/eye) 
is expected to be even lower. The half-life of PP-001 after intravitreal injection in rabbits was 
between 12 and 21 hours in ocular tissues and between 5 and 6 hours in peripheral blood. PP-001 
does not elicit ocular melanin binding properties as shown in an in vivo ocular distribution study 
that compared pigmented rats with albino rats. 
1.3.3 Non-Clinical Safety and Toxicology 
Non-clinical safety and toxicology studies included acute (intravitreal) and repeated dose 
(intravenous) toxicity testing in rabbits and rats, and in vitro genotoxicity testing in bacterial and 
mammalian cells. All pivotal non-clinical studies were conducted in a country that is a member 
of the Organisation for Economic Co-operation and Development (OECD) Mutual Acceptance 
of Data program in accordance with the OECD Test Guidelines and Principles of Good 
Laboratory Practice (GLP) and respective ICH and Committee for Medicinal Products for 
Human Use guidance. 
When PP-001 was given via the systemic route the no-observed-effect level (NOEL) in a 14-day 
repeated dose toxicity study in rats was 1 mg/kg body weight, which was the highest dose tested. 
In this study, the detected systemic exposure was several hundred fold higher than the expected 
exposures after intravitreal therapeutic doses in humans and thus provides an adequate safety 
margin with respect to systemic toxicity.  
In an ocular extended single dose toxicity study conducted in rabbits (12 eyes dosed in 6 
animals), intravitreal injection of PP-001 was shown to be safe with a no-observed-adverse-
effect-level (NOAEL) of 10 µg/eye over an observation period of 15 days. Higher doses (20 and 
30 µg/eye) resulted in adverse changes in retina (retina detachment and retinal tear, focal 
exudation etc.), choroid (vessel enlargement, choroidal exudates) and vitreous (floaters). There 
was no test item related intraocular pressure (IOP) abnormality or any other finding in body 
weight change, food and water consumption and clinical pathology in any dose group observed 
during the course of the study. Toxicokinetic analysis of blood plasma after dosing with 30 µg in 
each eye established that maximum plasma concentration (43.5 ng/ml) was reached at 4 h post 
dosing and PP-001 was not detectable after 8 h post dosing. There was no test item related 
intraocular pressure (IOP) abnormality or any other finding in body weight change, food and 
water consumption and clinical pathology in any dose group observed during the course of the 
study 
PP-001 did not show genotoxic potential in S. typhimurium tester strains and a mouse lymphoma 
assay. No phototoxic risk is indicated since PP-001 does not absorb light at relevant 
wavelengths. 
 
Summary of Clinical Data 
This is a first time in human study therefore no clinical data is available.

3. 
STUDY DESIGN 
This prospective, multi-centre, open-label, non-randomized, consecutive study will be conducted 
in accordance with the European Union (EU) Clinical Trial Directive 2001/20/EC and 
2005/28/EC, The Medicines for Human Use (Clinical Trials) Regulations 2004 and current 
amendments, the Declaration of Helsinki (revised version of Edinburgh, Scotland 2000), Good 
Manufacturing Practice (GMP), Good Clinical Practice (GCP) and the current national 
regulations and guidelines, approved by both the local ethics committee and regulatory authority. 
Eighteen patients older than 18 years of age will be enrolled and receive a single intravitreal 
injection of PP-001. Patients must have chronic, posterior uveitis, intermediate uveitis or 
panuveitis requiring treatment and have been receiving an adequate therapy of e.g. systemic 
corticosteroid treatment or immunosuppressive therapy (e.g. azathioprine, methotrexate, 
cyclosporine, mycophenolate, tacrolimus) or any combination thereof. Any systemic therapy at 
study start should be continued throughout the study. Patients must have best-corrected Early 
Treatment Diabetic Retinopathy Study (ETDRS) visual acuity of 10 letters or better

Confidential Information 
(approximately 1/35 or 0.032) but equal or less than 50 letters (approximately 20/100 or 0.2) in 
the study eye.  
Patients must give written consent for the study before any study assessments are performed. 
Screening assessments will be performed 8–14 days before dosing. Baseline assessments will be 
performed no more than 7 days before injection. The study will involve eight study visits 
(Screening, Baseline, the day of injection (Day 0) and Days 2, 7, 14, 21 and 28) and telephone 
calls on Day 1 and Day 40.  
Patients will be divided into three cohorts of four patients. Patients will receive the following 
treatments administered as a single intravitreal injection: 
• Cohort 1 will receive 0.3 µg of PP-001 
• Cohort 2 will receive 0.6 µg of PP-001 
• Cohort 3 will receive 1.2 µg of PP-001 
The patients within a cohort will be dosed consecutively with a minimum time interval of 7 days 
between the dosing of the previous patient and the dosing of the next patient. The results from 
each dosing day will be reviewed before progressing towards the subsequent dosing day. The 
next cohort will only receive PP-001 after the previous cohort has completed all study sessions 
up to Day 28 and no safety issues have been identified after reviewed by the Safety data 
management board (SDMB). 
After 12 patients have been treated in the three cohorts and after all patients have finished the 
last follow up an interim analysis by the SDMB will be conducted to identify potential safety 
issues and to determine the highest tolerable dose. If no safety issue can be identified, then a 
fourth, higher dose will be given to a cohort of four patients (Cohort 4). The dose for a potential 
Cohort 4 will be 2.1 µg of PP-001. 
If safety issues are identified in any of Cohorts 2, 3 or 4, two additional patients will receive the 
next lower dose.  
Safety will be assessed by monitoring vital signs and recording of AEs (see Section 7). Safety 
procedures will be performed by the Investigator or suitably qualified individuals designated by 
the Investigator. 
Pharmacokinetic sampling will take place at Screening, 4 h ± 1 h after injection and on Day 2.  
Efficacy will be evaluated by ophthalmic examination. 
An overview of the schedule of assessments/procedures is presented in Table 1. 
 
Study Rationale 
PP-001 is proposed for development as an intravitreal injection for the treatment of NIU. This 
first time in human study will investigate the safety, tolerability and efficacy of single ascending 
doses of PP-001 using intravitreal injection in male and female patients. The study population 
will comprise patients with NIU and an otherwise good state of health to ensure homogeneity. 
Patients with chronic posterior uveitis, intermediate uveitis or panuveitis, for whom maximal 
medical treatment failed or who are unable to tolerate medical treatment because of adverse 
ocular or systemic effects will be included in this study. The data generated in this study will

Version 3.1_GER 03 November 2017

Confidential Information 
support the progression of a well-tolerated dose of PP-001, administered by intravitreal injection 
in patients with NIU.  
3.1.1 Dose Rationale 
PP-001 will be developed for the treatment of non-infectious posterior uveitis. 
For evaluation of a safe human starting dose, a calculation based on a mg/kg basis is not 
considered appropriate for intravitreally administered drugs. However, in the EU there is no 
applicable guidance available in this regard and thus, reference is made to the Food and Drug 
Administration’s Note for Guidance Estimating the Maximum Safe Starting Dose in Initial 
Clinical Trials [Food and Drug Administration, 2005]. For PP-001, the starting dose was 
evaluated by normalization the compartmental volumes and concentrations of the therapeutic 
doses between rabbits and humans. Using the different volumes for vitreous humour (rabbit and 
human) the NOAEL dose of 10 µg/eye in rabbits would therefore correspond to a human dose of 
26.7 µg/eye.  
Since this study will involve patients data on the minimum efficacious dose of PP-001 and its 
exposure in vitreous and retinal tissues (which are both considered the main target tissues) are 
considered. More importantly, this calculation provides an additional safety margin compared to 
a simple normalization based on differences in the size of eyes (rabbit vs. human) and is to be 
preferred because of the steep dose-toxicity curve that was observed in the intravitreal toxicity 
study in rabbits. 
An oral dose of 25 mg/kg was shown to be efficacious in the EAU rat model. This dose level led 
to an ocular AUC of 1.27 µg·h/g and 4.8 µg·h/g for vitreous and retina in pigmented animals, 
respectively. Exposure of vitreous and retina have been determined after intravitreal injection of 
various doses of PP-001 into pigmented rabbit eyes. By applying a linear extrapolation it was 
calculated that an efficacious dose of approximately 0.25–0.36 µg/eye in rabbits corresponds to 
an efficacious retinal AUC of 4.8 µg·h/g, whereas a dose of 0.20–0.27 µg per rabbit eye is 
needed to reach an efficacious vitreous AUC of 1.27 µg·h/g (see Table 2).  
Considering the higher vitreous volume of the human eye, a dose of 0.54 to 0.96 µg/eye is 
expected to achieve efficacious exposure in the human vitreous and retina, respectively.

* Calculated efficacious dose based on PK study in rabbits; values are calculated by dividing the applied intravitreal 
dose/eye by obtained the AUC from time 0 to time t in pigmented rabbits (see Section 1.3.2) multiplied by the 
efficacious AUC in pigmented rats (see Section 1.3.2); ** Calculated efficacious human dose using the vitreous 
volume difference between rabbit and human. 
 
It must be noted that the calculation above is only an estimation. Due to inter-individual 
variations in the volume of vitreous humour, an even lower starting dose of 0.3 µg/eye is 
proposed for this first time in human study. 
With a starting dose of 0.3 µg/eye an appropriate safety margin of 86 is provided as depicted 
below in Table 3.

In conclusion, the proposed starting dose of 0.3 µg/eye provides an adequate safety margin for 
clinical study PP-001-1001 with respect to local and systemic toxicity. Plasma levels following a 
single intravitreal dose of 0.3 µg/eye will lead to a negligibly low plasma exposure of PP-001 (if 
present at all) and thus no systemic toxicity is expected. Regarding local effects observed in the 
eye the starting dose provides a safety margin >86-fold compared to the calculated human 
equivalent dose derived from an extended single dose study in rabbits, where 10 µg/eye was 
considered to be the NOAEL. 
Consecutive dosing and careful monitoring using state of the art methodology will provide 
additional safety level. 
 
Potential Risks and Benefits to Human Patients 
PP-001 is a novel chemical molecule to inhibit a known enzyme called DHODH, a known drug 
target for systemic treatment of rheumatoid arthritis, psoriatic arthritis and multiple sclerosis. 
PP-001 is a novel inhibitor of DHODH and has the potential to deliver a new treatment for 
patients with severe non-infectious uveitis. Currently patients suffering from intermediate and/or 
the posterior uveitis (i.e., the vitreous body and retina/choroid are affected) are routinely treated 
with systemic corticosteroids with well known side effects. The future expected therapeutic role 
of PP-001 will be as a steroid-sparing agent that will allow steroid doses to be tapered quickly or 
even replaced.  
In this proposed study the safety and tolerability of single doses of intravitreally administered 
PP-001 will be evaluated. Based on the preclinical pharmacokinetics the ocular half-life is

Confidential Information 
expected to be less than 20 h and the systemic exposure is expected to be below the biological 
activity and close to or below the limit of detection of the applied bioanalytical method 
(10 ng/ml). Due to the local treatment (intravitreal injection) and the preclinical data on plasma 
exposure of PP-001 it is unlikely that there will be any systemic exposure of PP-001 in human 
and therefore no systemic effects of PP-001 are expected. 
This study will identify the tolerated doses at expected efficacious ocular exposures and will 
serve as the basis for further studies long term acting PP-001. 
The inclusion and exclusion criteria restrict access to the study to severely affected patients with 
severely compromised visual acuity 
At this stage of development, toxicity of PP-001 in human eyes cannot be ruled out but the risk is 
considered low based on the safety factor calculated using preclinical data. Considering the 
expected low systemic exposure of PP-001, potential systemic side effects known from other 
DHODH inhibitors are not expected. In order to minimize this risk, the first patient will receive 
the lowest dose, which is approximately 90 times less than the established safe concentration in 
preclinical studies. The next patient will only receive an injection after a safety gap of 7 days and 
review of all data by the SDMB. The next highest dose will only be administered after the safety 
of the lower dose has been established. 
The procedure of an injection into an inflamed eye has been established in other approved types 
of uveitis treatment such as Ozurdex and Retisert, in Phase III studies with sirolimus and the off-
label use of intraocular triamcinolone. These studies have not shown any significant risks 
associated with eye injections. Concerns have been raised over the application of small crystals 
into the eye because of the potential to induce an autoinflammatory reaction. The type and 
structure of the preparation used in this study should reduce this risk.  
Study PP-001-1001 will provide valuable data on the safety, tolerance and pharmacokinetic 
profile of PP-001 after single dosing in patients with severe uveitis, which will help to define the 
dose for future studies. 
In conclusion, based on the currently available safety data, PP-001 has an acceptable benefit/risk 
profile in patients at doses in the estimated therapeutic range of 0.3–1.2 (2.1) µg/eye, and at the 
same time might reduce some of the inflammatory indices in patients with severe uveitis who 
have no treatment alternative.

The date, start and stop time of each dose will be recorded in the electronic case report form 
(eCRF). 
 
Occupational Safety 
PP-001 is not expected to pose any occupational safety risk to site staff under normal conditions 
of use and administration. 
A Material Safety Data Sheet describing occupational hazards and recommended handling 
precautions either will be provided to the Investigator, where this is required by local laws, or is 
available upon request from Panoptes Pharma GesmbH. 
In line with good handling of chemical products, precautions are to be taken to avoid skin and 
eye contact. In the case of unintentional occupational exposure, any signs or symptoms should be 
treated appropriately and the Sponsor notified. 
6. 
STUDY ASSESSMENTS AND PROCEDURE 
A schedule of study procedures is presented in Table 1. Patients meeting the eligibility criteria 
listed in Section 4 may be enrolled in the study after the nature and purpose of the protocol have 

Panoptes Pharma GesmbH 
Clinical Protocol PP-001-1001 
Version 3.1_GER 03 November 2017

Confidential Information 
been explained and written informed consent to participate has been voluntarily given. Study 
personnel must complete all screening procedures after informed consent is signed and before 
the first dose of study drug. Note: assessments performed as part of routine standard of care 
before consent may be used to satisfy study screening requirements; however, no study-specific 
procedures may be performed before informed consent is given. 
The time and day on which PP-001 is administered will be regarded as 0 h on Day 0. The 
Investigator should make every effort to perform procedures at the scheduled times and to record 
the actual time of the procedures, where appropriate, in the patient's eCRF. 
For patients who are screened (i.e., those with signed written informed consent) but do not meet 
the screening criteria, the reason for screening failure will be recorded. 
 
Surgical Procedure 
The study treatment procedure must be performed only by the qualified Investigator in an 
operating room, surgical suite, or in an office setting using sterile technique. The study 
medication kit should be readily available during the procedure. The final diluted PP-001 
solution will be injected at the required dose at a volume of 100 µL (see Section 8). For safety 
reasons, an emergency pars plana vitrectomy aiming at removal of injected drug will be available 
in case of a severe adverse event including, but limited to, acute loss of visual acuity or acute 
inflammatory or toxic response to injection. It is therefore mandatory for patients to remain in 
the hospital for at least 4 hours after the injection procedure.  
 
Medical/Surgical History 
A medical and surgical history will be taken at Screening. All medical history findings that have 
been present/active within 5 years before enrolment will be entered into the eCRF regardless of 
clinical relevance or presence at study start. Medical history findings that have not been present 
within the 5 years before enrolment will be recorded if deemed clinically relevant to the conduct 
of the study by the Investigator. The medical history should include drug allergy history and past 
and present smoking status. 
 
Physical Examination 
A complete physical examination will be performed by the Investigator at Screening. At the time 
points specified in Table 1, subsequent directed physical examinations will be performed 
according to standard institutional practices and must be documented in source documents. 
Body weight and height will be measured at Screening only. 
 
Vital Signs 
Vital signs (heart rate [HR] and blood pressure [BP]) will be recorded at time points specified in 
Table 1. Blood pressure and HR will be assessed according to standard practice at the clinical sites. 
Study personnel will record vital sign measurements in the eCRF. 

Panoptes Pharma GesmbH 
Clinical Protocol PP-001-1001 
Version 3.1_GER 03 November 2017  
Page 29 of 54 
Confidential Information 
Vital signs measurements are to be repeated if clinically significant changes or machine errors 
occur. Out of range BP and HR will be repeated at the Investigator’s discretion. Semi-supine BP 
and HR will be measured more frequently if warranted by the clinical condition of the patient. 
 
Twelve-Lead Electrocardiogram 
Triplicate 12-lead electrocardiograms (ECGs) will be performed within a 5-minute interval at the 
time points outlined in Table 1. 
The patient should be stabilized in a supine position for 5 minutes before recording the ECG at 
Screening. The ECG recordings should allow a full assessment of QT intervals. Machine-read 
values for QTc/QTcF will be evaluated for determination of eligibility at Screening. If the 
quality of the ECG is insufficient then it must be repeated. All ECG data must be reviewed by 
the attending physician and any findings of clinical significance found following Screening will 
be recorded as AEs in the eCRF. In addition, advice may be sought from appropriate 
cardiologists, if necessary. All ECGs will be made available to the Sponsor for review and might 
be sent to a Cardiac Core Laboratory for further evaluation.   
 
Clinical Laboratory Tests 
Safety laboratory tests will be performed at the time points specified in Table 1 and sent to a 
local laboratory. Additional tests may be performed at the discretion of the Investigator if 
deemed clinically appropriate. If required, samples may be sent to a central laboratory for 
confirmation of local results. 
A full list of the clinical laboratory tests that will be performed and analyzed is presented in 
Section 21.1. 
Any safety laboratory results outside the normal range will be repeated at the discretion of the 
Investigator and will be evaluated by the Investigator or designee as “clinically significant (CS)” 
or “not clinically significant (NCS).” Any CS value should be repeated as necessary and 
followed until resolution. 
 
Opthalmic Examination Procedures 
Detailed ophthalmic examination will be used to evaluate screening criteria, determine efficacy 
and as a safety measure. All procedures should be performed at the times outlined in Table 1. 
The primary efficacy variable is vitreous haze. The ophthalmologist will grade vitreous haze by 
viewing the optic disc and posterior retina using an indirect ophthalmoscope set to large beam 
and mid power illumination with a 20-diopter lens. Low ambient lighting and the same indirect 
ophthalmoscope should be used whenever possible. The scale is based on the following unit 
scale categorized as follows: 
0 
No inflammation 
+0.5 
Trace inflammation (slight blurring of the optic disc margins and/or 
loss of the NFL reflex) 
+1 
Mild blurring of retinal vessels and optic nerve

6.7.1 Electroretinography 
Patients will receive anaesthetic drops and the patient’s eyelids will be kept open with a 
speculum. An electrode is gently placed on each eye and an additional electrode is placed on the 
skin to provide a ground. Electrical signals produced by the retina in response to light will be 
measured with the electrodes. 
6.7.2 Fluorescein Angiogram 
Fluoroscein angiograms will be used to assess blood flow in the retina and choroid. Dilation eye 
drops will be given to patients, who will then place their chin on a chin rest and forehead against 
a support bar. Images of the retina, papilla, macular region and the choroid will be taken. 
6.7.3 Optical Coherence Tomography 
Three-dimensional images of the eye will be generated using optical coherence tomography 
(OCT). OTC is a laser-based, non-invasive, diagnostic system providing high-resolution images 
of the retina and retinal thickness. Optical coherence tomography will be performed in the study 
eye only. High-resolution cross-sectional images will be examined for physiological 
abnormalities. 
6.7.4 Best Corrected Visual Acuity 
Best corrected visual acuity will be measured in both eyes using an ETDRS chart. Patients will 
be asked to read the smallest letters they can from a chart. 
6.7.5 Visual Field Measurement 
Computerised 30° visual field measurement will be conducted. 
6.7.6 Visually Evoked Cortical Potential 
The electrical response of the primary visual cortex to a visual stimulus will be measured. Three 
electrodes will be placed on the scalp. One electrode will measure the response, another 
electrode will be placed at a reference location, typically on the forehead or top of the head. The 
third electrode will be placed on the patient’s ear for grounding. These electrodes will be 
connected to a visual electrodiagnostic test system.

6.7.7 Intraocular Pressure 
Intraocular pressure will be measured using Goldman contact tonometry. 
6.7.8 Slit Lamp Examination 
A slit lamp will be used to examine the conjuctiva, cornea, anterior chamber including grading of 
cells and haze (classified according to Standardization of Uveitis Nomenclature Working Group 
criteria), lens (classified according to Lens opacities classification system II) and vitreal haze 
(classified according to Standardization of Uveitis Nomenclature Working Group). 
6.7.9 Dilated Fundoscopy 
Visualization of the fundus will be carried out as part of an eye exam by dilating the patient’s 
pupils. This procedure will include slit lamp biomicroscopy of the fundus. 
6.7.10 Corneal endothelial microscopy 
The corneal endothelial layer will be assessed by microscopic evaluation of the cornea.  
6.7.11 Fundus photography 
The eye, retina, retinal vasculature, optic disc, macula and posterior pole will be photographed 
using a retinal camera. Vitreous haze will also be documented. 
6.7.12 Amsler grid 
To test for macular degeneration, patients will be asked to look at an Amsler grid and wear their 
reading glasses. With one eye covered, patients will be asked to state if any of the lines appear 
wavy, blurred or distorted, whether there are missing or dark areas in the grid. The test will be 
repeated for both eyes. 
6.7.13 Health Outcome Measures 
Patient-reported outcomes will be assessed using the National Eye Institute Visual Functioning 
Questionnaire 25 (VFQ-25), SF36™ Health Survey Version 2 (SF-36v2) and EuroQol-5 
Dimensions Health Questionnaire (EQ-5D). For additional information on these outcome 
measures, refer to the Procedure Manual. 
 
Telephone Interview 
A telephone interview will take place on Day 1 to evaluate the safety of PP-001. Standardized 
questions will be used and will include (but not be limited to) assessment of pain, blurred vision, 
change in visual acuity and eye redness.

date of dosing, nominal sampling time, aliquot ID (e.g. A, B, C). Promptly following 
centrifugation, plasma specimens will be immediately frozen and stored at approximately -20 °C 
or cooler until transported for analysis. The total time period from blood withdrawal to storage of 
plasma at approximately -20 °C should not exceed 60 minutes. The primary samples (aliquot A) 
should be transferred to the A&M analytical laboratory on dry ice. 
6.12.2 Assay Methodology 
Pharmacokinetic samples will be analyzed for the concentration of PP-001 using a validated 
liquid chromatography-tandem mass spectrometry method at the bioanalytical laboratory. 
 
Total Blood Volume Collected 
Patients will have approximately 20 mL of blood collected for safety and pharmacokinetic 
evaluations during the study. 
 
Discontinuation from Treatment or Study 
Patients are free to withdraw from the study at any time for any reason. Patients may be 
withdrawn from the study at the discretion of the Principal Investigator or Sub-Investigator at 
any time. Once a patient has been withdrawn from the study, they may not be re-entered. Patients 
who withdraw or who are withdrawn from the study will not be replaced. If a patient is 
discontinued from treatment or from the study, the reason for discontinuation will be collected in 
the eCRF. 
If a patient is prematurely withdrawn from study drug treatment, the Investigator should make 
every effort to retain the patient in the study and perform all procedures scheduled for the 
follow-up. Any patient withdrawn from treatment due to an AE, serious AE (SAE) or clinically 
significant safety value will be evaluated by the Investigator, or a monitoring physician, and will 
be treated and/or followed up until the symptoms or values have either resolved or are assessed 
as stable by the Investigator. 
6.14.1 Discontinuation from Study 
A patient may be discontinued prematurely from the study for the following reasons: 
• Withdrawal by patient (specify the reason in the eCRF) 
• Lost to follow-up 
• Death 
• Physician decision (i.e., assessment that it is not in the patient’s best interest to 
continue, or another reason; specify the reason in the eCRF) 
• The sponsor may shut down the study at any time (specify the reason in the eCRF)

6.14.2 Individual Stopping Criteria 
If an individual Patient meets one or more of the following criteria, the SDMB and Investigator 
will discuss whether the patient should be withdrawn from the study or dosing, or postponed 
until the criterion is no longer met: 
• Patient develops a concurrent illness, condition or procedural complication that would 
interfere with the patient’s continued participation 
• Patient experiences a study drug-related SAE as determined by the Investigator 
Patients may also be withdrawn from the study at any time at the discretion of the Investigator 
for other safety or tolerability reasons, or for behavioural or administrative reasons. 
A patient may also withdraw from the study at any time at their own request. 
If a patient is prematurely withdrawn from study treatment, the Investigator should make every 
effort to retain the patient in the study and to perform all procedures scheduled for the follow-up 
visit. Any patient withdrawn from treatment due to an AE, SAE or clinically significant 
abnormal laboratory test value will be evaluated by the Investigator, or a monitoring physician, 
and will be treated and/or followed up until the symptoms or values have either resolved or are 
assessed as stable by the Investigator. 
6.14.3 Study Stopping Criteria 
Dosing of further patients will be stopped if the following criterion is observed: 
• A moderate or severe AE classified as being possibly, probably or definitively study-
drug related or potential major safety concerns as identified by the Investigator after 
consultation with the SDMB are reported in more than 50% of patients in the same 
cohort.  
Dosing will be stopped or the dose decreased if: 
• One patient on any dosing day shows a possibly, probably or definitively study-drug-
related SAE judged by the Investigator after consultation with the SDMB or other 
potential major safety concerns are identified by the Investigator in agreement with the 
SDMB. 
6.14.4 Lost to Follow-up 
If a patient does not report to the study site for a scheduled visit, study personnel will make four 
contact attempts: three telephone contact attempts and, if these are unsuccessful, a certified letter 
will be sent to the patient. The patient will be considered lost to follow-up if (1) upon receipt of 
delivery confirmation of the certified letter the patient does not contact the site or (2) the certified 
letter is returned as undeliverable within 7 days. 
 
Premature Termination of the Trial  
In the event of any SAE, which, in the investigator’s opinion, justifies termination of the trial, 
dosing will be stopped and the sponsor will be informed immediately. The sponsor and

safety issue occur during the trial. If the trial is terminated prematurely, the investigator will 
return all eCRFs to the sponsor, and the sponsor or investigator, as appropriate, will provide a 
written statement of the reasons for termination. The sponsor will ensure that the relevant 
regulatory agencies and main research ethics committees are notified. 
 
Contraceptive measures 
Female patients of childbearing potential are not allowed to participate in this study. The 
definition of non-childbearing potential includes the following: 
• Surgically sterile (e.g., hysterectomy with or without oophorectomy; fallopian 
tube ligation; endometrial ablation), at least 30 days prior to signature of the 
Informed Consent form 
• At least 3 years post-menopause (i.e., 4 years post last menstrual period), or 
menopause confirmed by follicle-stimulating hormone (FSH) testing.  
Fertile men need to adhere to contraceptive measures in accordance with the “Recommendations 
related to contraception and pregnancy testing in clinical trials, September 2014” of the Clinical 
Trials Facilitation Group. 
Male patients must ensure that one highly effective method of contraception combined with an 
acceptable method of contraception is used for the entire duration of the study, from first dose up 
to the study follow-up visit, and must refrain from fathering a child in the 3 months following the 
last study drug administration. Male patients must agree with their female partners prior to 
screening to use the above specified methods of contraception while receiving protocol-specified 
medication, and for 3 months after stopping the medication. 
Highly effective methods of birth control are defined as those that result in a low failure (i.e., 
< 1 % per year) when used consistently and correctly, such as:  
- combined (estrogen and progestogen containing) hormonal contraception associated with 
inhibition of ovulation (oral, intravaginal, transdermal) 
- progestogen-only hormonal contraception associated with inhibition of ovulation (oral, 
injectable, implantable)  
- intrauterine device  
- intrauterine hormone-releasing system  
- bilateral tubal occlusion 
- vasectomised partner 
- sexual abstinence 
Acceptable birth control methods are defined as those that result in a failure rate of more than 
1% per year and include: 
- progestogen-only hormonal contraception, where inhibition of ovulation is not the primary 
mode of action 
- male or female condom with or without spermicide 
- cap, diaphragm or sponge with spermicide; 
 
Periodic abstinence and withdrawal are not acceptable methods of contraception. Female 
partners of male patients must be informed by their male partners about the need to use one

highly effective methods of birth control combined with an acceptable method of birth control as 
defined above.

ADVERSE EVENTS 
An AE is any untoward medical occurrence in a patient or clinical investigation patient 
administered a pharmaceutical product that does not necessarily have a causal relationship with 
this treatment. An AE can therefore be any unfavourable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease temporally associated with the use of an 
investigational product, whether or not related to the investigational medicinal product. 
Any pre-existing conditions or signs and/or symptoms present in a patient before the start of the 
study (i.e., before informed consent) should be recorded as medical/surgical history. Any 
medical occurrences that are new or worsened from the time of informed consent and up to and 
including the final visit must be reported as AEs or SAEs. All AEs and SAEs must be recorded 
irrespective of whether they are considered drug-related. 
Patients will be monitored throughout the study for adverse reactions to the study medications 
and/or procedures at each study visit. Questions will be posed in a non-leading manner so as not 
to bias the response. In addition to questioning at specific time points, patients will be 
encouraged to report any AEs spontaneously. Any patient with an AE, SAE or clinically 
significant abnormal laboratory test value will be evaluated by the Investigator, or a monitoring 
physician, and will be treated and/or followed up until the symptoms or values have resolved or 
are assessed as stable by the Investigator. A physician, either at the Investigative site or at a 
nearby hospital emergency room, will administer treatment of any SAEs. Where appropriate, 
medical tests and examinations may be performed to ensure that an AE has fully resolved. 
Adverse events will be monitored throughout the study from the time a patient is consented 
through the final follow-up visit; SAEs are to be collected from the time of consent through to 
the follow-up visit. Whenever possible, a specific disease or syndrome rather than individual 
associated signs and symptoms should be identified by the Investigator and recorded on the 
patient's eCRF. However, if an observed or reported sign or symptom is not considered a 
component of a specific disease or syndrome by the Investigator, it should be recorded as a 
separate AE on the patient's eCRF. 
Each AE or SAE reported will be assessed for severity and the date and time of onset (if 
available), time relationship to dosing, duration and outcome of each event will be noted. 
Laboratory abnormalities are not considered AEs unless they are associated with clinical signs 
and symptoms or require medical intervention. Clinically significant abnormal clinical laboratory 
findings or other abnormal assessments that are associated with the disease being studied, unless 
judged by the Investigator as more severe than expected for the patient’s condition, or that are 
present or detected at the start of the study and do not worsen, will not be reported as AEs or 
SAEs. 
The Investigator will exercise medical and scientific judgment in deciding whether an abnormal 
clinical laboratory finding or other abnormal assessment is clinically significant.

Confidential Information 
 
Assessment of Severity (Intensity) 
The following definitions for rating severity (intensity) will be used: 
Mild:  
A type of AE that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual 
activities of daily living. 
Moderate:  
A type of AE that is usually alleviated with specific therapeutic intervention. The 
event interferes with usual activities of daily living, causing discomfort but the 
patient is still able to function. 
Severe: 
The type of AE that interrupts usual activities of daily living, or significantly 
affects clinical status, or may require intensive therapeutic intervention. 
 
Assessment of Relationship to Study Drug 
The Investigator will use his/her clinical judgment to explain each AE and determine its 
relationship, if any, to study drug treatment. Alternative causes, such as natural history of the 
underlying diseases, concomitant therapy, other risk factors and the temporal relationship of the 
event to the study drug will be considered and investigated. The Investigator will also consult the 
Investigator’s Brochure in the determination of his/her assessment. Causality should be assessed 
using the following categories: 
Not Related  
The event could readily be explained by factors not involving the study 
drug and a temporal relationship with the study drug did not exist. 
Possibly Related  
There was some temporal relationship between the event and the 
administration of the study drug and the event was unlikely to be explained 
by the patient’s medical condition or other therapies. 
Probably Related  
The temporal relationship between the event and the administration of the 
study drug was suggestive, and the event was less likely to be explained by 
the patient’s medical condition or other therapies. 
Definitely Related  The event followed a reasonable temporal sequence from administration of 
the study drug, followed a known or suspected response pattern to the 
study drug, was confirmed by improvement upon stopping the study drug 
(dechallenge) and reappeared upon repeated exposure (rechallenge). (Note: 
this is not to be construed as requiring re-exposure of the patient, however, 
a category of definitely related can only be used when recurrence was 
observed). 
 
Serious Adverse Events 
An SAE is any untoward medical occurrence that: 
• Results in death 
• Is life-threatening 
• Results in persistent or significant disability/incapacity 

Panoptes Pharma GesmbH 
Clinical Protocol PP-001-1001 
Version 3.1_GER 03 November 2017  
Page 38 of 54 
Confidential Information 
• Requires in patient hospitalization or prolongation of existing hospitalization 
• Is a congenital anomaly/birth defect 
• Is an important medical event 
NOTE: medical or scientific judgment should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be immediately 
life threatening or result in death or hospitalization but may jeopardize the patient or may require 
medical or surgical intervention to prevent one of the other outcomes listed in the above 
definition. These should also be considered serious. Examples of such events are invasive or 
malignant cancers, intensive treatment in an emergency room or at home for allergic 
bronchospasm, blood dyscrasias or convulsions that do not result in hospitalization or 
development of drug dependency or drug abuse. 
All SAEs for patients occurring from the time of informed consent through to the follow-up visit 
must be reported to Panoptes Pharma GesmbH or their representative within 24 h of the 
knowledge of the occurrence (this refers to any AE that meets one or more of the aforementioned 
serious criteria). Reporting is done by completing the SAE form electronically in the eCRF 
system for the study.  
The SAE form should be completed in as much detail as possible but a lack of complete 
information should not delay the reporting of the SAE.  
There may be situations when an SAE has occurred and the Investigator has minimal information 
to include in the initial report to Panoptes Pharma GesmbH. However, it is very important that 
the Investigator always makes an assessment of causality for every event prior to transmission of 
the SAE report form to Panoptes Pharma GesmbH. The Investigator may change his/her opinion 
of causality in light of follow-up information, amending the SAE report form accordingly. The 
causality assessment is one of the criteria used when determining regulatory reporting 
requirements. 
The Investigator will provide the assessment of causality as per instructions on the SAE form in 
the CRF. 
If an SAE occurs during this study, the following (Sponsor) personnel should be contacted: 
Dr. Franz Obermayr: 
Phone (office and after-hours):  
+43 664 8557369 
 
Other Reportable Events 
Certain events that occur in the absence of an AE should be reported to the Sponsor as Other 
Reportable Events. These include the following: 
• Pregnancy exposure (female partners of male patient becomes pregnant while taking 
study drug) 
• Although pregnancy is not technically an AE, all pregnancies must be followed to 
conclusion to determine their outcome. This information is important for both 
drug safety and public health concerns. It is the responsibility of the Investigator 
or designee to report any pregnancy in a patient that occurs during this study to 
Panoptes Pharma GesmbH or their representative.

Confidential Information 
• Accidental exposure (someone other than the study patient was exposed to study drug) 
• Overdose (patient received more than the prescribed dose of study drug within a given 
timeframe) 
• Other medication errors that potentially place patients at a greater risk of harm than 
was previously known or recognized (e.g., study drug was administered by an incorrect 
route)

8.1.2 Storage of Study Drugs 
Access to all study drugs must be restricted to designated study personnel throughout the study. 
PP-001 will be stored between 15 and 25°C. 
8.1.3 Product Accountability 
The Investigator is responsible for study medication accountability, reconciliation and record 
maintenance. In accordance with all applicable regulatory requirements, the Investigator or 
designated study site personnel must maintain study drug accountability records throughout the 
course of the study. This person(s) will document the amount of study drug received from the 
supplier, the amounts dispensed to patients as well as lot numbers and expiration/retest date of 
study medications. 
At the conclusion of the study, any unused study drug will either be returned to a 
Sponsor-designated recipient or destroyed at the site after discussion with the Sponsor. If no 
supplies remain, this will be recorded in the drug accountability section of the final monitoring 
report. 
All unused study drug provided by the Sponsor will be retained for purposes of drug 
accountability. In addition, empty and partially used vials of PP-001 will be retained by the 
pharmacy for the purposes of drug accountability. Every effort will be made to retain used 
containers of PP-001 in the pharmacy for the purposes of drug accountability. 
A member of the Sponsor’s clinical operations staff (or designee) will check the supplies storage, 
dispensing procedures and records at regular intervals throughout the study.

Safety Analysis 
Safety will be evaluated in the Safety Analysis Set by presenting summaries of AEs and vital 
signs. 
Summary tables will be provided for all TEAEs. A treatment-emergent AE is defined as an AE 
with a start date and time on or after the first dose of study drug. Adverse events will be coded 
using the Medical Dictionary for Regulatory Activities (MedDRA®). The number and 
percentage of patients with TEAEs will be tabulated by system organ class and MedDRA 
Preferred Term for each treatment group and by severity and relationship to treatment. 
Adverse events leading to premature discontinuation from the study drug and serious TEAEs 
will be presented either in a table or a listing. 
Descriptive statistics of vital signs and the change from baseline for each scheduled evaluation 
will be summarized at each study visit and the worst overall post-baseline value will be provided. 
The number and percent of patients with treatment-emergent values with potential clinical 
significance will be tabulated. 
 
Pharmacokinetic Analyses 
The concentration of PP-001 in plasma will be measured in blood samples taken at Screening, 
4 h ± 1 h after dosing and on Day 2. 
 
Efficacy analysis 
All efficacy endpoints will be presented in terms of descriptive statistics. 
The relationship between the change from baseline of an efficacy endpoint and exposure to 
PP-001 will be investigated. 
 
Handling of Missing Data 
Missing values will not be imputed. 
 
Interim Analysis 
The results from each dosing day of the first cohort will be reviewed before progressing with the 
subsequent dosing day. The next cohort will only commence with dosing after the previous 
cohort has completed all study sessions up to day 28 and no safety issues have been identified 
after being reviewed by the SDMB. 
After a total of 12 patients have been treated in the three cohorts and after all patients have 
finished the last follow-up, an interim analysis by the SDMB will be conducted to identify 
potential safety issues and to determine the highest tolerable dose. If no safety issue can be 
identified, then a fourth dose with a higher amount of PP-001 will be given to Cohort 4 
comprising of four patients. The dose for a potential Cohort 4 will be defined after completion of 
Cohorts 1 to 3.

STUDY MONITORING 
 
Clinical Monitoring 
All aspects of the study will be carefully monitored by the Sponsor’s authorized individuals, 
acting as agents of the sponsor with respect to current GCP and Standard Operating Procedures 
for compliance with applicable government regulations. These individuals will have access to all 
records necessary to ensure integrity of the data and will periodically review the progress of the 
study with the Principal Investigator. 
Frequent communication between the study site and the Sponsor is essential to ensure that the 
patient safety is monitored adequately. The Investigator will make safety assessments on an 
ongoing basis. The Sponsor’s medical monitor will review safety information from all study sites 
as it becomes available throughout the study. 
 
Safety Data Monitoring Board 
Safety will be assessed by monitoring the results of the ophthalmic examinations and AEs 
throughout the study. Risk assessments will be made by the SDMB after each cohort in written 
form and throughout the study based on the above. For details please refer to SDMB policy. 
11. 
INDEPENDENT ETHICS COMMITTEE APPROVAL 
The Principal Investigator agrees to provide the Independent Ethics Committee (IEC) with all 
appropriate material, including a copy of the informed consent. The study will not be initiated 
until the Investigator obtains written approval of the research plan (protocol) and the informed 
consent document from the appropriate IEC and copies of these documents are received by 
Panoptes Pharma GesmbH. 
It is the Investigator’s responsibility to obtain IEC approval for all subsequent major changes to 
the protocol, in compliance with local law. Appropriate reports on the progress of this study will 
be made by the Investigator to the IEC and Sponsor in accordance with applicable government 
regulations and in agreement with policy established by the Sponsor. 
12. 
ETHICAL CONDUCT OF THE STUDY 
This clinical study will be conducted in compliance with this Protocol, will be conducted in 
accordance with the EU Clinical Trial Directive 2001/20/EC and 2005/28/EC, The Medicines for 
Human Use (Clinical Trials) Regulations 2004 and current amendments, the Declaration of

INFORMED CONSENT 
The International Conference on Harmonization (ICH) has issued guidelines to provide 
protection for human patients in clinical investigations. The ICH Tripartite Guideline for GCP 
establishes the general requirements for informed consent. 
A properly executed, written informed consent in compliance with the terms of these guidelines 
shall be obtained from each patient before entering the study, or before performing any unusual 
or non-routine procedure in relation to the study. The purpose of the study, procedures to be 
carried out, and potential hazards will be described to each potential patient in non-technical 
terms. Patients (or their legally authorized representative) will be required to read, voluntarily 
sign, and date an informed consent form summarizing the discussion at Screening, and will be 
assured that they may withdraw from the study at any time without jeopardizing their medical 
care. 
Patients will sign and date one copy of the informed consent form, which will be photocopied. 
The copy will be retained by the patient and the original will be retained on file by the 
Investigator. 
The consent form must be approved by the appropriate IEC and Sponsor before study initiation 
at a study site. Any subsequent changes to the approved informed consent form must be 
reviewed and approved by the appropriate IEC and Sponsor before implementation. 
14. 
QUALITY ASSURANCE/QUALITY CONTROL 
Standard Operating Procedures belonging to Panoptes Pharma GesmbH or designee(s) will be 
adhered to for all activities relevant to the quality of the study and are routinely monitored by the 
Quality Assurance (QA) Division. 
Data will undergo quality control checks before clinical database lock. Sponsor-designated, 
independent monitors will be responsible for monitoring the study and its data within the eCRFs. 
A QA audit of this study may be conducted by the Sponsor or Sponsor’s designee. The QA 
auditor will have access to all medical records, the Investigator’s study-related files and 
correspondence and information in the informed consent documentation of this study. 
An inspection of this study may be conducted by a regulatory agency. The Investigator agrees to 
contact the Sponsor as soon as possible, but not later than within 1 week, upon notification of an 
inspection by a regulatory agency. The Investigator agrees to allow the Inspector direct access to 
all relevant documents and to allocate his/her time and that of study site personnel to the 
Inspector to discuss findings in any relevant issues. The Investigator will allow Sponsor 
personnel to be present as an observer during a regulatory inspection, if requested. 
15. 
DATA HANDLING AND RECORD KEEPING 
 
Data Handling 
Data will be recorded at sites using eCRFs and reviewed by the Sponsor or designee during 
monitoring visits. The recorded data in the eCRF system will be verified with source documents. 
All corrections or changes made to any study data must be appropriately tracked in an audit trail 

Panoptes Pharma GesmbH 
Clinical Protocol PP-001-1001 
Version 3.1_GER 03 November 2017  
Page 45 of 54 
Confidential Information 
in the eCRF system. The eCRFs will be considered complete when all missing, incorrect, and/or 
inconsistent data have been accounted for. Data collected at baseline will only be entered into the 
eCRF if the patient is eligible for study participation following review of the data by the 
Investigator or designee. 
Adverse events, concomitant medication data and clinical observations will be in the patients’ 
hospital notes, or recorded on source data forms, and will be transferred into the eCRF after 
assessment by the Investigator or designee. 
Data produced by automatic devices with original print-outs (e.g., BP measurements) will be 
included in the source documentation. Any results outside the normal range should be designated 
by the Investigator or designee as “clinically significant” or “not clinically significant”. 
 
Patient Confidentiality 
The Investigator and his/her staff will be required to manage patient data collected for the study in 
accordance with applicable laws and regulations on personal data protection. 
Data collected during this study may be used to support the development, registration, or 
marketing of PP-001. Panoptes Pharma GesmbH will control all data collected during the study, 
and will abide by the EU Directive on Data Privacy concerning the processing and use of 
patients’ personal data. For the purpose of data privacy legislation, Panoptes Pharma GesmbH 
will be the data controller. 
After patients have consented to take part in the study their medical records and the data 
collected during the study will be reviewed by Panoptes Pharma GesmbH or its representatives. 
These records and data may, in addition, be reviewed by the following: independent auditors 
who validate the data on behalf of Panoptes Pharma GesmbH; third parties with whom Panoptes 
Pharma GesmbH may develop, register, or market PP-001; national or local regulatory 
authorities and the IECs that gave approval for this study to proceed. 
Patients will be known by a unique number; however, their date of birth can also be collected if 
not in contradiction with any requirements (e.g., from IECs) and used to assist Panoptes Pharma 
GesmbH to verify the accuracy of the data, for example, that the laboratory results are assigned 
to the correct patient. The results of this study may be recorded and transferred to and used in 
other countries throughout the world, which may not afford the same level of protection that 
applies within the EU. The purpose of any such transfer would be to support regulatory 
submissions in other countries. 
 
Computer Systems 
Data will be processed using a validated computer system conforming to regulatory 
requirements. 
 
Data Entry 
Data must be recorded using the eCRF system as the study is in progress. All study site 
personnel must log into the system using their secure user name and password in order to enter,

Confidential Information 
review, or correct study data. These procedures must comply with EU Directives 2001/20/EC 
and 2005/28/EC for EU sites. All passwords will be strictly confidential.  
 
Data Validation 
Validation checks programmed within the eCRF system as well as supplemental validation 
performed via review of the downloaded data will be applied to the data in order to ensure 
accurate, consistent and reliable data. Data identified as erroneous, or data that are missing, will 
be referred to the investigative site for resolution through data queries. 
The eCRFs must be reviewed and electronically signed by the Investigator who signed the 
protocol. 
 
Record Keeping 
Raw data generated in connection with this study as well as an original copy of the final clinical 
study report, will be retained in archive until at least 5 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated marketing 
applications in an ICH region or at least 5 years have elapsed since the formal discontinuation of 
clinical development of PP-001. These documents will be retained for a longer period if required 
by the applicable regulatory requirements or by an agreement with the Sponsor. It is the 
responsibility of the Sponsor to inform the Investigator/Institution as to when these documents 
no longer need to be retained. 
As required under European Directive 2005/28/EC, Article 17, all ‘essential documents’ (as 
described in the ICH GCP Guidelines) must be retained by Panoptes Pharma GesmbH and the 
Investigator for at least 5 years after the completion of the clinical study. Therefore, all studies, 
independent of where they were conducted in the world, must follow this requirement in the 
event a submission is ever made in the EU. These documents may be retained for a longer 
period; however, if required by the applicable regulatory requirements or by an agreement with 
Panoptes Pharma GesmbH. It is the responsibility of Panoptes Pharma GesmbH to inform the 
Investigator as to when these documents no longer need to be retained. The Investigator must 
obtain written permission from Panoptes Pharma GesmbH before the destruction of any study 
document. 
These records must be made available at reasonable times for inspection and duplication, if 
required, by national or foreign Regulatory Authorities in accordance with regulatory 
requirements.

agency, I will notify Panoptes Pharma GesmbH as soon as possible thereafter (no later than 
1 week) 
• Submission of the proposed clinical investigation, including the protocol, the informed 
consent documents, and any other patient materials required for study conduct, to a duly 
constituted Independent Ethics Committee (IEC) 
• Obtaining written informed consent only after ensuring that the patient, or his/her legal 
representative, is competent to make the decision, understands what is contained in the 
informed consent document, and is consenting voluntarily. Written informed consent will be 
obtained prior to administration of study drug or any non-routine study-related procedures; 
the document contains all the essential elements of consent and has been previously approved 
by the sponsor and IEC. Reference of written informed consent will be provided in source 
documentation 
• Submission of any protocol amendment to the IEC. If the protocol amendment change(s) 
increase risk to the study population, full IEC written approval must be obtained prior to 
implementation. For changes that do not involve increased risk or affect the validity of the 
investigation or the patient's rights, prior IEC approval may be obtained by expedited review 
• Adherence to the study protocol. Documentation and explanation of individual post-
enrolment protocol deviations will be recorded in the source documentation at the site and be
