Unlocking Innovation: The Role of Patents in Orphan Drug Development

Unlocking Innovation: The Role of Patents in Orphan Drug Development  

Introduction

BACKGROUND

The development of novel pharmaceuticals has historically focused on treating widespread diseases, leaving those affected by rare diseases, also known as orphan diseases, with limited or no treatment options. An orphan drug is a medication designed to address such conditions, which impact a relatively small number of individuals. The creation of orphan drugs is a significant challenge due to the smaller patient populations, high research costs, and limited commercial potential. Patents play a crucial role in incentivizing pharmaceutical companies to invest in orphan drug research and development, leading to innovative treatments for patients who would otherwise be left without hope.

Patent Protection and Pharmaceutical Innovation

Patent protection and pharmaceutical innovation are two interconnected concepts that play a crucial role in the development and progress of the pharmaceutical industry. Let's explore each of these terms:

Patent Protection:

Patent protection is a legal mechanism that grants exclusive rights to inventors or innovators for a specific period, typically 20 years from the filing date of the patent application. During this time, the patent holder has the exclusive right to make, use, and sell the invention, preventing others from using, making, or selling the same invention without the patent holder's permission. 

Pharmaceutical Innovation:

Pharmaceutical innovation refers to the process of discovering, developing, and bringing new drugs and medical treatments to the market. It involves extensive research and development (R&D) efforts to identify novel compounds, conduct preclinical and clinical trials to assess safety and efficacy, obtain regulatory approvals, and eventually launch the product for commercial use.

Orphan Drug Market Exclusivity:

In addition to patent protection, orphan drugs may also receive a period of market exclusivity as part of the incentives offered by regulatory authorities. Market exclusivity means that for a specific period, usually seven years in the United States and ten years in the European Union, the regulatory agency will not approve another similar drug for the same orphan indication.

Balancing Innovation and Access

Orphan drugs are medications developed to treat rare diseases or conditions that affect a relatively small number of people. While these drugs provide essential treatment options for patients with rare disorders, they also face various accessibility challenges due to their unique characteristics and limited market size. 

Orphan drug pricing and affordability are critical aspects of healthcare that focus on drugs developed to treat rare diseases or conditions, often referred to as orphan diseases. These conditions are relatively uncommon and affect a small number of people, making them less attractive to pharmaceutical companies from a purely economic standpoint.

Compulsory license and parallel imports

A compulsory license is a legal mechanism that allows a government to grant a license for the production, use, or sale of a patented drug without the consent of the patent holder. This action effectively suspends the exclusivity rights of the patent holder and permits other manufacturers to produce and distribute the drug.

Parallel imports, also known as parallel trade or gray market trade, occur when genuine products (including pharmaceuticals) are imported into a country from another country without the authorization of the patent holder or trademark owner. This can be a contentious issue in the pharmaceutical industry, particularly concerning orphan drugs.

Abigail Alliance for Better Access to Developmental Drugs v. Eschenbach (2006) 

Summary: The Abigail Alliance for Better Access to Developmental Drugs, a non-profit organization, filed a lawsuit against the Food and Drug Administration (FDA) Commissioner, Lester M. Crawford, and the Department of Health and Human Services (HHS) Secretary, Michael O. Leavitt, in the United States District Court for the District of Columbia.

Ever greening and Patent Thickets

"Ever greening" refers to a strategy used by pharmaceutical companies to extend the exclusivity and profitability of a drug beyond its original patent expiration date. This is typically achieved by obtaining new patents for certain aspects of the drug, such as its formulation, dosing regimen, or method of delivery. By doing so, the company can prevent generic competitors from entering the market with cheaper versions of the drug. 

"Patent thickets" refer to a situation where multiple patents, often owned by the same company or several companies, cover various aspects of a single product or technology. This overlapping web of patents can create a complex and dense thicket of intellectual property rights around a particular drug or medical technology.

Patent Trolling and Litigation

"Patent tolling" is a legal concept related to the extension of patent rights beyond the standard expiration date. In the context of orphan drugs, patent tolling can have significant implications for drug exclusivity and market competition.

The rationale behind patent tolling for orphan drugs is to incentivize pharmaceutical companies to invest in the development of medications for rare diseases. Since the patient population for orphan drugs is relatively small, the potential revenue from sales may not be sufficient to justify the research and development costs without additional incentives.

Mohd., Ahmed V U.O.I (2014) 

The Delhi High Court made some landmark pronouncements on the right to health in the context of access to medicines as it affects a patient suffering from a rare disease. The central issue before the court was whether a child born to poor parents and who is suffering from Gaucher’s disease chronic and rare disease) is entitled to free medical treatment especially when the treatment for the disease is known, the prognosis is good, and there is every likelihood that the child can lead a normal life. The court observed that the cost of the drugs for this disease is exorbitant because it is a rare disease It  was argued on behalf of the child that, since the drugs needed for the treatment of the child is available in India, both the Central Government and the Government of Delhi had an obligation under Article 21 of the Constitution to provide free treatment to the child and other patients in the same situation. 

Conclusion 

National Policy for Treatment of Rare Diseases, 2017 

The policy highlights the measures and steps, both in the short as well as in the long term, that need to be taken to deal comprehensively with rare diseases the policy intends to constitute an Inter-ministerial Consultative Committee to coordinate and steer the initiatives of different ministries and departments on rare diseases. It also mentions the creation of a corpus fund at Central and State level for funding treatment of rare diseases.

The policy aims to create a patient registry for diseases housed in Indian Council of Medical Research (ICMR). National Policy for Treatment of Rare Diseases, 2021 

NPRD in 2021 for the treatment of rare disease patients. Aim: To increase focus on indigenous research and local production of medicines. To lower the cost of treatment of rare diseases.

To screen and detect rare diseases early at early stages, which will in turn help in their prevention.
