Product Development

Our Approach

We, iGEM Stockholm 2017, believe that lung probiotics are the future, and we want to be at the forefront of this field together with PROlung.



To prepare PROlung to become a possible start-up in the future, we have conducted different parts of a theoretical product development strategy with the help of the book BIODESIGN The Process of Innovating Medical Technologies.



Pharmaceutical and biotechnological development are usually characterized by the development of a product looking for an uncertain market. In our opinion, the final customer should be always in the center of the development process and, because of this, we have used the product development strategy of the MedTech industry as our baseline, as we search for a way to provide a high-value solution for the patients.



In order to develop our product, having the final customer always in the center, we have included a section concerning this in the analysis of the disease state fundamentals, the existing solutions, the stakeholders involved in this area and the landscape of market for a treatment to respiratory diseases related to high mucus production. But most importantly, we have found the need behind our product, by listening to the opinions of different stakeholders.



Through the background analysis we performed and studies of customers’ needs, we were able to successfully develop the product design. For the product we had designed we made a theoretical study of the regulations it would be subjected to, the ethical concerns it may raise and the intellectual property protection we could apply for, and the product could interfere with. At the end of the process, we were also able to determine how the product could be reimbursed in healthcare and a possible business model for it. We believe that conducting all this would give PROlung a head start in becoming a company.



Since we know the target audience for this document has a very varied background, we have included, in the beginning of each segment, a short description of its purpose. We hope that this description of and business concepts and the word list of complex medical terms we have also included can inspire future teams to think about the product development of their projects.

We have divided our product development in two different parts: the journey to finding a need and the journey to putting a product in the market. We have taken this decision for a matter of simplicity and thought this is the key point to do so as the product design step of the product development is a turning point for the innovator in which there is a change from a more social, value based mindset to a more utilitary and practical one.



Disease state fundamentals

What is this?

Disease state fundamentals is establishing a detailed knowledge of the relevant disease state, with a particular focus on its mechanism of action. A disease state fundamentals is key to validating any need and understanding how it can best be addressed.

   

Word list

Physiology: The way in which bodily part functions
Epidemiology: The study and analysis of the patterns, causes, and effects of health and disease conditions in defined populations
Pneumothorax: There is a tear in the lung and air escapes into the chest cavity.
Dyspnea: Shortness of breath

Recurrent sinusitis: the small, air-filled cavities behind your cheekbones and forehead get inflamed
Mucociliary clearance: self-clearing mechanism of the bronchi

Anatomy of the lungs

The human lungs are a pair of large, spongy organs optimized for gas exchange between our blood and the air, as our bodies require oxygen in order to survive.

The air that you breathe goes down your windpipe into tubes in your lungs called bronchial tubes, that branch many times into smaller, thinner tubes called bronchioles. These tubes end in bunches of tiny round air sacs called alveoli. Small blood vessels called capillaries run along the walls of the air sacks. To protect the body from these foreign particles, the lungs are covered in something called mucus.1



Physiology of the lungs

When air reaches the air sacs, oxygen passes through the air sac walls into the capillary blood At the same time, a waste product, carbon dioxide (CO2), is removed from the blood, into the air sacs. This gas exchange process brings in oxygen for the body to use for vital functions and removes the CO2.



The airways and air sacs are elastic breathing in, each air sack fills up with air, like a balloon, when breathing out, the air sacs deflate and the air goes out.



The mucus that covers the lungs is a viscous substance which traps these foreign molecules and consequently, prevents them from entering the body. Tiny hairs called cilia constantly move the mucus with the entrapped pathogens upwards and out of the lungs. Thus, the mucus functions as a protection against the outside world, continuously keeping the airways clear of foreign particles.2

    

Cystic fibrosis (CF)

Epidemiology

Varies across the globe. In the European Union: 1 in 2000-3000. In the United States of America: 1 in 3500. However, it is severely underdiagnosed in rest of the world. More than 75 percent of people with CF are diagnosed by age 2.

 

Physiology

In CF, a mutation in the CFTR gene changes a protein that regulates the movement of salt in and out of cells. CF is a genetic disease which mostly affects the lungs but also the pancreas, kidney, liver and intestine. The result is thick, sticky mucus in the respiratory, digestive and reproductive systems, as well as increased salt in sweat. As the airways are clogged up by mucus overproduction, it decreases the mucociliary clearance which further on causes infections by making it easier for bacteria to grow and trigger more mucus overproduction. This may ultimately form a plug which will completely stop the airflow .

Clinical presentation

CF is characterized by chronic or recurrent cough, recurrent wheezing, recurrent pneumonia, dyspnea on exertion and chest pain.

Clinical outcomes

The life expectancy is around 40-50 years old.

Economic impact

The mean annual healthcare cost for treating CF is 15,571$. Lifetime healthcare costs are approximately 306,332$ .

Chronic Obstructive Pulmonary Disease (COPD)

 

Epidemiology

Currently, 64 million people are diagnosed with COPD. It causes 3 million deaths per year (5% of all deaths in 2015) . Most of the time, COPD is diagnosed in middle-aged or older adults.

 

Physiology

COPD is a progressive disease that makes it hard to breathe out. In COPD, less air flows in and out of the airways because of one or more of the following: The airways and air sacs lose their elastic quality. (emphysema) The walls between many of the air sacs are destroyed. (emphysema) The walls of the airways become thick and inflamed (emphysema) The airways become inflamed and produce more mucus than usual and can become clogged (CB).

 

Clinical presentation

COPD can cause coughing that produces large amounts of mucus, wheezing, shortness of breath and chest tightness.

 

Clinical outcomes

Life expectancy is based largely on the severity or stage of the disease, generally 65 to 70 years.

 

Economic impact

The annual cost of healthcare utilisation [excluding treatment costs and diagnostic tests] per individual was estimated to be 2,364$ .

      
   

Asthma

Epidemiology

235 million people have asthma, it caused 383 000 deaths in 2015 . Asthma most commonly starts to appear during childhood.

Physiology

People who have asthma have inflamed airways. The inflammation makes the airways swollen and very sensitive. The airways tend to react strongly to certain inhaled substances. When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. Asthma also is related to the overproduction of mucus, which needs to be coughed up.

Clinical presentation

Asthma symptoms are coughing, wheezing, shortness of breath and chest tightness.

Clinical outcomes

For the most part, a person with asthma can have a life expectancy as long as someone without asthma.

Economic impact

 

In 2015, the health system costs of asthma are estimated to be $1.2 billion.

          

Existing solutions

What is this?

Analysing the existing solutions is to explain the current and emerging solutions, how they work, when they are used, how effective they are, their cost and the overall value they deliver. The aim is to clarify the gap in existing solutions, where new opportunities become apparent.

Summary

The most common medications for cystic fibrosis, COPD and asthma are the inhalation devices like bronchodilators, mucus thinners, and steroids. A famous new drug on the market is Orkambi. Thick mucus also contributes to bad bacteria in the lungs were often antibiotics are necessary. These medications are always taken together with airway clearance techniques and in severe cases, a lung transplant may be needed.

   

Word list

Bullectomy: Surgical removal of a bulla, which is a dilated airspace in the lung parenchyma Osteoporosis: Bones becoming less dense due to the loss of bone material.
Exacerbation: Increase in the severity of a disease
Hoarseness: Abnormal voice changes

Cystic Fibrosis

Current commercially available approved drug class are:

Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) modulators (ivacaftor (Kalydeco®) and lumacaftor/ivacaftor (Orkambi®).) The Lumacaftor moves the defective CFTR protein to the correct place on the cell surface, and ivacaftor increases the protein's activity once it is in place. Orkambi is today one of the most attractive medications for CF but the therapeutic effect only targets a subpopulation people with specific CF mutations.3

Bronchodilators is an inhalation device that helps widen the airways, and can also be used for asthma and COPD patients. There are two different types, short-acting and long-acting and can be used before other treatments and before exercise.

Mucus thinners, such as Mucolytic drugs is a type of inhalation medicine that alters the chemical characteristics of mucus to decrease its viscosity and facilitate its removal. There are two types hypertonic saline works by increasing the amount of sodium in the airways and Dornase alfa (a DNA functions by cutting DNA strands released by white blood cells, which makes the mucus thinner.

Potential disadvantages of inhalation medication in CF patients compared to other drug administrations are:

Uncertainty about drug dose at the target site, severely affected lung areas may not be reached, drug delivery depends on inhalation technique and device performance, local side effects (e.g., cough, airway narrowing, hoarseness), variable systemic drug absorption, time-consuming drug administration, need for education and training, limited information on drug interactions in the lung, specific drugs may need specific delivery devices, poor adherence, potential pollution of the environment, potential device contamination and patient infection, need for hygiene control and maintenance of the equipment and limits social functioning.4

Anti-infective drugs include antibiotics and antibacterials, antifungals, antivirals, and antiprotozoals. These work by either killing the infectious agent or by inhibiting it from spreading Antiinflammatory drugs have two main purposes, to act as painkillers or to reduce inflammation.5

Pancreatic enzyme supplements are taken by mouth with the purpose to digest carbohydrates, proteins, and fats, absorb essential nutrients such as vitamins and minerals and help the patient gain and maintain a healthy weight.6

Lung Transplantation can extend and improve patient’s quality of life, but it involves an extensive evaluation process and a commitment to living the lifestyle required to keep your new lungs healthy.

COPD

Bronchodilators (mentioned above) Inhaled steroids such as inhaled corticosteroid medications can reduce airway inflammation and help prevent exacerbations. Side effects may include bruising, oral infections and hoarseness.

Oral steroids work for patients who have a moderate or severe acute exacerbation. Short courses (for example, five days) of oral corticosteroids can prevent further worsening of COPD, however, long-term use of these medications can have serious side effects, such as weight gain, diabetes, osteoporosis, cataracts and an increased risk of infection.

Phosphodiesterase-4 inhibitors is a new type of medication approved for patients with severe COPD and symptoms of chronic bronchitis. One example is roflumilast (Daliresp), a phosphodiesterase-4 inhibitor. This drug decreases airway inflammation and relaxes the airways. Common side effects include diarrhea and weight loss.

Theophylline is a medication, which might help improve breathing and prevent exacerbations. Side effects may include nausea, headache, fast heartbeat and tremor. Side effects are dose-related, and low doses are recommended.

Antibiotics can act against respiratory infections, such as acute bronchitis and pneumonia.

Surgery is an option for some people with some forms of severe emphysema who aren't helped sufficiently by medications alone. Surgical options include:

  • Lung volume reduction surgery
  • Lung transplant
  • Bullectomy
  • 7

    Asthma

    Asthma medications are divided into two main parts, long term, and short term medication, where the first acts to reduce airway inflammation, which helps prevent symptoms from starting and the second one acts to give rapid, short-term symptom relief during an asthma attack. Asthma has very similar medications as COPD such as the inhaled steroids, bronchodilators and Theophylline.

    Other long-term control medicines include:

  • Cromolyn

  • Omalizumab

  • Inhaled long-acting beta2-agonists
  • 8
  • Leukotriene modifiers

  • Short terms include:

  • Ipratropium (Atrovent)

  • Prednisone

  • Methylprednisolone

  • Inhaled short-acting beta2-agonists

  • Airway clearance techniques

    In addition to medication, techniques can be taught by a physiotherapist to help restore clear airways in all of our targeted diseases. Such exercises includes: active cycle of breathing techniques (ACBT), a technique that involves a sequence of relaxed breathing, followed by deep breathing exercises and then huffing, autogenic drainage, a series of gentle breathing techniques that clear mucus from the lungs, modified postural drainage, a technique that involves changing your position to make it easier to remove mucus from your lungs and airway clearance devices, a handheld devices that use vibration and air pressure to help remove mucus from your airways.9
