HEALTHCARE MARKETS

Dialysis in end-stage renal disease

Learn more
Visionary new non-glucose based osmotic agent in peritoneal dialysis (PD). Adaptable and stable fluid elimination during both short and long dwells. Reduces metabolic stress, such as glucose and insulin spikes, and weight gain. Expected to prolong PD treatment window by slowing glucose-induced peritoneal fibrosis. Improves quality of life.
Kidney failure is a USD 80 BN highly profitable market growing at 4% p.a.
  • 25 million people worldwide are expected to suffer from kidney failure (end-stage renal disease)
  • 3rd fastest global growing cause of death
  • 11th leading global cause of death
  • Renal disease consumes 7% of U.S. Medicare budget

Global Dialysis Market Revenue

Causes of kidney failure
  • Key factors: diabetes, high blood pressure, obesity
  • High blood sugar and high blood pressure damages blood vessels and nephrons (tiny filters) in kidneys, ultimately leading to kidney failure
  • Patients with End-Stage Renal Disease (ESRD) must receive renal replacement therapy (i.e. blood filtration through dialysis or kidney transplantation) to survive
Chronic Kidney Disease ~700m patients worldwide
Kidney Failure (ESRD – end stage renal disease) ~25m patients worldwide

Treated ESRD (Dialysis)
> 2m patients worldwide

Hemodialysis (HD) ~88% of patients
Peritoneal Dialysis (PD) ~12% of patients
Transplantation ~0.5m patients in USA

Kidney Replacement Treatment

Hemodialysis (HD)

Pump and filter

1. Blood is drawn from the patient

2. Blood passes through a dialysis machine container a dialyzer

3. Dialyzer removes toxins, waste products, and extra fluid

4. Cleaned blood is returned to the patient

3-5h of Treatment in a Clinic or Hospital, 3x a Week

  • Time-consuming and limited mobility
  • Side effects: fatigue, cramps, headaches, nausea
  • Vascular access issues over time
  • Fresenius and DaVita are largest players
  • Annual cost per patient: USD 70’000*

Peritoneal dialysis (PD)

Soft cleaning process using the patient’s peritoneal membrane as a filter

1.  A cleansing fluid (dialysate) is introduced into the patient’s abdomen through a surgically implanted catheter.

2. The dialysate remains in the body for several hours, allowing waste products and excess fluids to pass from the blood into the solution.

3. After the dwell time, the used dialysate, now containing waste products, is drained out.

Conveniently performed at home, at work, while travelling Performed 3 times manually during the day and 1 time automatically overnight using a machine called a cycler.
  • Greater flexibility and independence
  • Less time-consuming
  • Higher first year survival rate (2-fold higher)
  • Extended treatment duration
  • Significantly better outcome for patients with heart failure (10% of dialysis patients)
  • Better preservation of kidney function, gentler on the body
  • Cost-effective: reduced need for infrastructure and personnel
  • Annual Cost per patient: USD 40’000*

HOW PERITONEAL
DIALYSIS (PD) WORKS

Filling

Dwelling

Draining

Repeats per day

PD IS THE BETTER TREATMENT OPTION, BUT HAS CURRENT LIMITATIONS, OPENING A MARKET OPPORTUNITY FOR OPTERION

Current daytime dwell solutions for PD rely on glucose, leading to metabolic health issues, specifically for diabetic patients (45% of dialysis patients).

  • Glucose Absorption: patients absorb 100-300g of glucose per day (36-110kg per year), equivalent to consuming 3-8 cans of Coca-Cola® daily.
  • Peritoneum Deterioration: the glucose load and high osmotic pressure cause serious deterioration of the peritoneum, shortening the treatment life.
  • Metabolic Impact: glucose absorption leads to weight gain and high insulin spikes, causing inflammation in the body.
  • Icodextrin® (Baxter): is based on complex polysaccharides, lacking the osmotic power required for day dwells.

OPTERION ODR IS A NON-GLUCOSE BASED OSMOTIC DRIVER FOR DAY AND NIGHT DWELLS

Fast acting, with continuous fluid elimination during day and night dwells

  • Personalized therapy due to different concentrations
  •  Reduced insulin response
  •  Novel patent-protected composition
  • Comprising Decadextrin – the Opterion new polysaccharide – and maltose

THE GAME CHANGER – OPTERION NON-GLUCOSE BASED OSMOTIC DRIVER – FOR DAY AND NIGHT DWELLS

Constant fluid elimination during short and long dwells

Group 395
  • Efficient ultrafiltration and clearance at every dwell
  • Improved patients’ quality of life

Fast acting, non-glucose-based osmotic driver

Group 395

Reduced weight gain, glucose, and insulin blood levels

Fast and efficient dialysis at reduced osmotic pressure

Group 395

Peritoneal membrane is protected and prolonges treatment duration

Flexible osmotic strength (different concentrations available)

Group 395

Optimal adaptation for patients’ dialysis needs

Polysaccharide osmotic driver with near-neutral pH

Group 395
  • Residual renal function preserved
  • No/low pain during dwell time

Less Glucose Degradation Products (GDP)

Group 395

Peritoneal membrane protected (reduced risk of peritonitis, longer PD use, preserved residual renal function)

Combination of all

  • Decreased dialysis side effects and improved quality of life
  • Prolonged PD therapy duration
  • Increasing attractivity of PD as dialysis therapy vs HD
  • Cost savings
