Highlights include: Current trends in CKD R&D efforts e.g. mechanisms of action of interest Major companies involved in the development of CKD therapies, and their therapeutic strategies The main body of the report will include an in-depth summary of each of the currently marketed products for CKD*, those in late-stage development (phase II/III, III or at submission), and those undergoing early stage development (phase I, I/II, II). Summary tables of molecules or programmes undergoing preclinical development is also included. A summary of company strategy will be provided for each company associated with a marketed product, or any company with two or more products in development for CKD At the front of the presentation are summary tables briefly describing all those marketed and clinical compounds, as well as a brief overview of the disease area and CKD market The Adis R&DI and CTI databases were used to source all information on individual drugs (both marketed and in development).* The NIH clinical trials database clinicaltrials.gov was used for additional clinical trial information, and information from individual company websites was also used where appropriate. * This report does not include compounds which are used off-label for CKD. 5 Chronic Kidney Disease Overview (1) Chronic kidney disease (CKD) is defined by the presence of a marker of kidney damage (e.g. proteinuria) or a decreased (<60 mL/min/1.73m2) glomerular filtration rate (GFR) for ≥3 months. Disease staging and severity is based on GFR.1 The major outcomes associated with the development of CKD include kidney failure, complications due to reduced kidney function and the development of cardiovascular disease (CVD). Subsequently, treatment goals include the prevention of disease progression and complications. CKD is a significant public health issue globally, affecting more than 50 million people In the USA, the first large epidemiological study to look at CKD in the general population found a prevalence of 11% in the US adult population2 A few years later, collection of data for the National Health and Nutrition Examination Survey (NHANES) reported a prevalence (for stage 1-4 CKD) of 13.1% in the 1999-2004 survey.3 CKD is closely linked to diabetes and cardiovascular disease; it is both a risk factor for, and a potential consequence of, CVD. Diabetes is the singles biggest risk factor for CKD, and is the leading cause of the problem in developed nations. Other risk factors include older age, hypertension, family history of CKD and smoking. 1 National Kidney Foundation – Kidney Disease Outcome Quality Initiative Clinical Practice Guidelines for CKD: Evaluation, Classification, and Stratification. 2 Coresh J, et al. Am J Kidney Dis 2003; 41: 1-12. 3 Coresh J, et al. J Am Med Assoc 2007; 298: 2038-2047. 6 Chronic Kidney Disease Overview (2) Management of CKD depends on the form of disease and the presence/absence of certain co-morbid conditions. The US National Kidney Foundation – Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) divides its recommendations into categories based on the type of CKD and the presence of comorbid conditions Table 1. Classification and management of comorbid conditions in CKD (NFK-KDOQI). National Kidney Foundation – Kidney Disease Outcome Quality Initiative Clinical Practice Guidelines for CKD: Evaluation, Classification, and Stratification. 7 Chronic Kidney Disease Overview (3) Treatment of CKD generally includes some or all of the following depending on disease severity: Specific therapy based on diagnosis Evaluation and management of comorbid conditions Slowing loss of kidney function Prevention and treatment of CVD and complications of decreased kidney function Preparation for kidney failure and kidney replacement Replacement of kidney function by dialysis and transplantation. Many pharmacologic therapies for CKD are also indicated for CVD, including ACE inhibitors, ARBs, beta-blockers, calcium channel blockers, direct renin inhibitors and diuretics. Many patients also receive glucose-lowering medications for co-morbid diabetes and statins for hyperlipidemia. The pharmaceutical market for CKD is therefore, relatively crowded with drugs that are also widely available in other indications, generally for hypertension or other forms of CVD None of these medications have been demonstrated to be truly disease modifying; they reduce the risk of CVD or slow the progression of kidney disease There has been an increase in the number of studies of traditional antihypertensives (such as ACEIs/ARBs) in patients with CKD, in order to increase their proportion of the also crowded antihypertensive market This relatively saturated market has led to interest in the development of novel pharmaceuticals with direct effects on processes underlying CKD, and this is what we see in the pipeline currently. 8 Chronic Kidney Disease Competitive Landscape: Marketed Compounds 9 Marketed Compounds Overview Drug Company Mechanism Launched Development Avapro® Sanofi-aventis (BristolMyers Squibb, Shionogi) Angiotensin type I receptor antagonist Diabetic nephropathies: Canada, EU, USA† -- Bristol-Myers Squibb (Merck & Co., Merck Sharp & Dohme) Angiotensin type I receptor antagonist Diabetic nephropathies: Canada, Japan, UK, USA†† (irbesartan) Cozaar® (losartan) Kremezin® (charcoal) Tanatril® (imidapril) Kureha Corp.

It is also available in Japan as a treatment for diabetic nephropathy. The agent has orphan drug status in Japan for the treatment of diabetic nephropathy. Tanatril® was originally developed by Tanabe Seiyaku (now Mitsubishi Tanabe Pharma). The drug is marketed by Xanodyne Pharmaceuticals in the USA and Canada, Merck in the EU, Trinity-Chiesi in the UK, Gerot in Austria and the Gerolymatos Group in Austria. In Japan the drug is being investigated in a phase II trial as a second-line treatment for hypertension in patients with autosomal dominant polycystic kidney disease (ADPKD), and in Italy, a phase III trial is comparing the agent with ramipril in patients with T2DM, hypertension and microalbuminuria. 11 Tanatril® Efficacy & Safety Summary In 76 patients with essential hypertension, Tanatril® 5-20 mg/day, alone or in combination with other antihypertensives (n=47), significantly reduced BP from baseline after 8 weeks. A total of 48/62 patients with mild-to-moderate hypertension responded (BP<150/90 mmHg) to 12 weeks of treatment with Tanatril® 2.5-20 mg/day (in combination with a fixed-dose thiazide diuretic). A multicentre, randomised, double-blind study compared the efficacy and tolerability of Tanatril® and enalapril in 223 patients with mild-to-moderate essential hypertension. Both agents showed similar antihypertensive efficacy; however Tanatril® was associated with a lower incidence of adverse events. In a randomised, double-blind, parallel study in 161 patients with essential hypertension, once-daily Tanatril® 5-20 mg/day for 8 weeks reduced mean sitting diastolic BP (DBP). DBP was reduced to ≤90mmHg in 52/106 Tanatril® recipients and 18/55 placebo recipients. In a multicentre (196), crossover study in 489 patients with mild-to-severe hypertension, 12weeks’ treatment with enalapril 5-10 mg/day induced cough in 39% of patients, compared with 15% of patients after the same doses of Tanatril®. A total of 21% of patients who did not experience cough while receiving Tanatril®, developed cough after switching to enalapril. Conversely, cough developed in 0.9% of patients who, having no cough on enalapril, crossed over to Tanatril®. In a randomised, double-blind, parallel study in 161 patients with essential hypertension, adverse effects reported by placebo and Tanatril® recipients, respectively, included: tiredness (2% and 5%), dizziness (2% and 6%), headache (9% and 6%) and vertigo (5% and 1%). 12 Tanatril® Key Clinical Trials Phase II Study for the Second-Line Treatment of Hypertension in Patients With Autosomal Dominant Polycystic Kidney Disease; ACEI vs. CCB.

The compound directly inhibits activation of NF-κB by binding to IKKβ, the kinase that regulates NF-κB activation. Bardoxolone methyl increases the estimated glomerular filtration rate (eGFR) of the kidneys. The agent is primarily being investigated for its efficacy in improving kidney function and/or delaying worsening of kidney function in patients with diabetic nephropathies. Phase III development of the agent, in patients with stage IV CKD associated with T2DM, was ongoing worldwide in the BEACON trial, however the trial was discontinued in October 2012 due to safety concerns. Bardoxolone methyl is an analogue of RTA 401, which was first synthesised by investigators at Dartmouth College and developed in co-operation with the University of Texas M.D. Anderson Cancer Centre. Reata subsequently licensed the agent to Kyowa Hakko Kirin in Japan, China, Taiwan, Korea and South-East Asia in January 2010; and to Abbott Laboratories for all markets outside of the US and certain Asian countries in September that same year. 17 Bardoxolone Methyl Efficacy & Safety Summary (1) In the open-label, randomised, phase II BEAM study, bardoxolone methyl sustained improvement in estimated glomerular filtration rate (eGFR) over 52 weeks in patients with moderate-to-severe CKD and T2DM. eGFR was significantly improved by up to 10.5 mL/min/1.73m2 in patients receiving 75mg bardoxolone methyl (p<0.001). Increases were 5.8 and 9.3 mL/min/1.73m2 for the 25mg and 150mg bardoxolone methyl groups, respectively, relative to placebo (p=0.002, 25mg; p<0.001, 150mg). Nineteen percent of patients who received placebo had a decline in eGFR of more than 25% over 52 weeks, compared with 9% of bardoxolone methyl-treated patients (p=0.058). Uric acid levels were significantly reduced in all bardoxolone methyl groups. Levels of blood urea nitrogen were also improved. Approximately 60% of patients receiving bardoxolone methyl showed a reduction in their classification of the severity of the disease after 24 weeks of treatment, compared with 17% of patients in the placebo group. Only 4% of patients in the bardoxolone methyl group had their disease worsened compared with 13% of placebo recipients. These were data from a randomised, double-blind phase IIb trial in 227 patients with T2DM and stage 3b (moderate) to severe (stage 4) CKD who received once daily bardoxolone methyl 25, 75 or 150mg or placebo. Approximately 3/4 of patients receiving bardoxolone methyl experienced an improvement in eGFR of ≥10%, including 1/4 of patients with an improvement of ≥50% compared with ≤2% in the placebo group (p<0.001). Patients in the bardoxolone methyl group demonstrated a mean increase in estimated GFR of 10 mL/min/1.72m2 compared with no change in the placebo group. 18 Bardoxolone Methyl Efficacy & Safety Summary (2) In the open-label, randomised, phase II BEAM study, the most common adverse event experienced with bardoxolone methyl was muscle spasm, over 52 weeks in patients (n=227) with moderate-to-severe CKD and T2DM. The incidence of muscle spasm was 42%, 61% and 59% in the 25, 75 and 150mg groups, respectively, compared with 18% in the placebo group. Transient elevations in liver enzymes, nausea, decreased appetite and hypomagnesaemia were also observed. 19 Bardoxolone Methyl Key Clinical Trials BEACON.

Atrasentan has been shown to reduce albuminuria in patients with diabetic nephropathies, and phase II development is underway in this indication in the US, Canada, Japan, Taiwan and Puerto Rico. The agent was previously being developed as a treatment for a variety of cancers; however, development in this indication appears to have been discontinued. Abbot is currently conducting three phase IIb trials of atrasenan, as a once-daily, adjunctive treatment for patients with diabetic nephropathy. Results from an earlier phase II trial of the drug in patients with T2DM and related diabetic nephropathy were published in the Journal of the American Society of Nephrology in March 2011. 25 Atrasentan Efficacy & Safety Summary Atrasentan 0.75mg and 1.75mg significantly reduced urine albumin-to-creatinine ratio (UACR) compared with placebo in a phase II dose-ranging trial in patients with diabetic nephropathy. In this randomised, double-blind, placebo-controlled trial, 89 subjects with received atrasentan 0.25mg, 0.75mg, 1.75mg or placebo for 8 weeks in combination with renin-angiotensin system (RAS) inhibitors. Patients in the 0.25, 0.75 and 1.75mg atrasentan groups had final UACR reductions from baseline of 21%, 42% and 35%, respectively, compared with 11% in the placebo group. Furthermore, a significantly greater proportion of patients in the 0.75mg group achieved a >40% reduction in UACR from baseline versus placebo (50% and 17%, respectively). Atrasentan 0.25mg, 0.75mg and 1.75 was associated with peripheral oedema (primarily mild) in this same phase II trial in 89 subjects with diabetic nephropathy. Oedema was observed in 14%, 18% and 46% of patients in the respective atrasentan cohorts, and 9% of patients in the placebo group. 26 Atrasentan Key Clinical Trials A Phase 2b, Prospective, Double-Blind, PlaceboControlled, Multicenter Study to Evaluate Efficacy and Safety of Atrasentan, Including Thoracic Bioimpedance, in Type 2 Diabetic Subjects With Nephropathy.

It does not appear to be developing any compounds at earlier stages of development in this area. Bristol-Myers Squibb is the owner of Cozaar ® (losartan), an orally administered, angiotensin type-II receptor blocker or ARB, which is widely available throughout the world as a treatment for hypertension. The agent was originally jointly developed by DuPont Pharmaceuticals (who were merged into Bristol-Myers Squibb in 2001 and Merck). Cozaar® is also available in Canada, Japan, the UK and the USA as a treatment for diabetic nephropathy, and a phase III trial in pediatric patients with hypertension is ongoing worldwide. Generic versions of Cozaar® are available for hypertension in Canada and the USA. 36 Bristol-Myers Squibb (2) Bristol-Myers Squibb also entered into a development and licensing agreement with Sanofi for Avapro® (irbesartan), an angiotensin type-II receptor blocker (ARB). The company co-developed Avapro® for both the treatment of hypertension and the treatment of diabetic nephropathy. Bristol-Myers Squibb markets Avapro® for hypertension and diabetic nephropathies in the USA. The agent is available worldwide for hypertension, and in the US, Canada and the EU for diabetic nephropathy. 37 Eli Lilly (1) Eli Lilly is involved in the development of three separate clinical-stage products in the CKD space, including the monoclonal antibody product LY-2382770, as well as baricitinib and LY-2623091. Another of their compounds, tabalumab, is also being investigated in an exploratory trial in patients with ESRD. Eli Lilly is developing the small molecule, janus kinase (JAK) 1 and 2 inhibitor, baricitinib, under an exclusive license from Incyte Corporation. A phase II trial of the agent is underway in patients with diabetic kidney disease at sites in the US, Puerto Rico and Japan. Approximately 250 patients are expected to be enrolled. Baricitinib is also in phase II trials for the treatment of rheumatoid arthritis and psoriasis. 38 Eli Lilly (2) Eli Lilly is also developing LY-238770, a monoclonal antibody product against transforming growth factor-beta (TGFβ) kinase, for the treament of diabetic kidney disease (diabetic nephropathies). A global phase II trial is underway at sites throughout the US, Australia, Europe, Israel and Puerto Rico, which is evaluating the ability of the antibody to protect kidney function in patients with diabetic nephropathies. Approximately 400 patients will be enrolled in total. LY-2623091, a mineralocorticoid receptor antagonist, is also in phase II trials with the company as a treatment for CKD; and Eli Lilly’s phase III rheumatoid arthritis candidate tabalumab (an anti-BAFF monoclonal antibody) is also being investigated in an exploratory trial in patients with ESRD. The exploratory phase II trial will investigate tabalumab in HLA-presensitized patients with ESRD who are awaiting kidney transplantation. The primary outcome measure will investigate single antigen reactivity and panel reactive antibodies. 39 Companies Involved in One Active Program Developer Role Drug Indication Phase (Country) Licensee (Country) Licensing availability Abbott Laboratories Originator Atrasentan Diabetic nephropathies II (Japan, Puerto Rico, USA) -- NA AM-Pharma Holding Originator Recombinant alkaline phosphatase Renal failure Preclinical (EU) -- NA Ampion Pharmaceuticals Originator Low-dose danazol Diabetic nephropathies I (Canada) -- In partnering discussions Angion Biomedica Originator BB-3 Acute renal failure II (Netherlands, USA) -- NA Angelini Group Originator Bindarit Diabetic nephropathies II (Italy, Slovenia) -- Yes, as of 22 June 2012 Bio3 Research Originator BIOCYSCAN™ Renal failure Preclinical (Italy) Daxley Group (Latin America) NA 40 Abbreviations ACEI(s) AE(s) ARBs BP CKD COPD CV CVD EU ESRD FDC GFR HCTZ HTN MI angiotensin converting enzyme inhibitor(s) adverse event(s) angiotensin type II receptor blockers(s) blood pressure chronic kidney disease chronic obstructive pulmonary disease cardiovascular CV disease European Union end-stage renal disease fixed-dose combination glomerular filtration rate hydrochlorothiazide hypertension myocardial infarction 41
