Prelims level: Biosimilar;
Mains level: Outdated Biosimilar Guidelines in India;
Why in the News?
The government has introduced two import-based initiatives to meet domestic needs, which could potentially dampen the growth of the domestic industry.
New medicines are generally under patent protection, preventing Indian companies from producing affordable generics/biosimilars.
Impact of two initiatives on Domestic Industry:
Global Tendering for 120 Medicines: The Department of Expenditure (DoE) allowed the Ministry of Health to buy 120 medicines, including popular anti-diabetes and anti-cancer drugs, through global tenders for government programs. This decision, which specifies certain brands for over 40 of these medicines, could increase the monopoly of foreign companies in India.
Customs Duty Removal on Cancer Medicines: The 2024-25 Union Budget proposed removing the 10-12% customs duty on three cancer medicines marketed by AstraZeneca. While intended to reduce prices, this measure is unlikely to significantly lower costs and may instead increase reliance on imports, further disadvantaging domestic producers.
Status of Indian Pharma
India is a leading manufacturer of vaccines, accounting for 60% of global production.
India supplies 70% of vaccines used by the WHO.
India is a major exporter of generic drugs, accounting for 20% of global exports.
The industry is expected to grow to over $130 billion by 2030.
What are Biosimilar guidelines?
Biosimilar guidelines in India are regulatory frameworks established by the Central Drugs Standard Control Organization (CDSCO) and theDepartment of Biotechnology (DBT) to govern the development, approval, and marketing of biosimilars.
Biosimilars are biologic medical products that are highly similar to an already approved original biologic (known as the reference product), with no clinically meaningful differences in terms of safety, purity, and potency.
Status Biosimilars:
Significant Market Size: The biosimilar market in India is valued at approximately $2.2 billion, and it is projected to reach $40 billion by 2030. This growth is driven by the expiration of patents for several key biologics, which opens the door for biosimilar development.
Product Approvals: As of now, over 70 biosimilars have been approved in India, covering a range of therapeutic areas, including oncology, diabetes, and autoimmune diseases. Notable examples include:
Adalimumab (for rheumatoid arthritis)
Trastuzumab (for breast cancer)
Filgrastim (for neutropenia)
Insulin glargine (for diabetes)
Outdated Biosimilar Guidelines in India:
Obsolete and Resource-Intensive:
India’s biosimilar guidelines are outdated, requiring mandatory animal studies, which are no longer necessary in developed countries like the U.S. and EU with stringent regulatory standards.
The guidelines also mandate clinical trials, while WHO and U.K. guidelines treat clinical trials as an exception rather than a rule.
Barrier for Domestic Producers:
The stringent requirements for animal studies and mandatory clinical trials create significant barriers for Indian producers, making it difficult for them to compete with their global counterparts.
Impact on Patient Access:
According to the International Generic and Biosimilar Medicines Association, eliminating these duplicative requirements could lead to significant savings in time and resources, ultimately improving patient access to affordable biosimilars.
Way forward:
Update Regulatory Guidelines: Modernize India’s biosimilar guidelines by removing unnecessary requirements like mandatory animal studies and clinical trials, aligning them with global standards to reduce barriers for domestic producers.
Support Local Production: Utilize provisions in the Patents Act to promote domestic manufacturing of affordable medicines, reducing reliance on imports and strengthening the local pharmaceutical industry.

Prelims level: Quantum Non-Locality
Why in the News?
A recent study published in Physical Review Letters by Indian researchers has revealed that a universal standard for measuring quantum non-locality is impossible.
What is Quantum Nonlocality?
Quantum Nonlocality is a mysterious connection between distant objects that challenges the classical idea of local realism, where no faster-than-light communication is allowed.
It’s crucial for technologies like secure communication, random number generation, and cryptographic key creation.
Easy Explanation:
Imagine two particles that are created together and then move far apart, even to opposite ends of the universe.
In classical physics, any effect on one particle would need a signal to travel to the other, taking time.
But in quantum physics, Quantum Nonlocality means these particles are instantly connected, affecting each other no matter the distance, as if linked by an invisible thread that works faster than light.
Historical Background: Bell’s Theorem (1964)
Physicist John Stewart Bell introduced a theorem that challenged the classical idea of ‘local realism’ in quantum systems.
Local Realism: In classical physics, objects are believed to have definite properties independent of observation and are only influenced by their immediate surroundings.
Quantum Challenge: Bell demonstrated that in quantum systems with multiple, distant parts, correlations appear that cannot be explained by local realism.
Bell’s theorem was confirmed through experiments, leading to the recognition of quantum nonlocality, which was honored with the 2022 Physics Nobel Prize.
Recent Research and Findings
The research demonstrates that a universal standard for measuring and comparing quantum nonlocality is impossible.
It shows that the nature of nonlocality varies based on the type of correlation, with infinite unique points on the correlation boundary.
There is no single, universal resource in the realm of quantum nonlocality; instead, each nonlocal resource is unique, capable of performing specific tasks that others cannot.
This observation plays a key role in secure communication, random number certification, and cryptographic key generation.

Prelims level: Hayflick Limit
Why in the News?
Leonard Hayflick, the renowned biomedical researcher who made a discovery about the limits of cell division in somatic cells (Hayflick Limit) has passed away at 98.
What is the Hayflick Limit?
In the early 1960s, Hayflick discovered that somatic (non-reproductive) cells have a finite number of divisions, typically between 40-60 times.
This phenomenon, the ‘Hayflick limit’ suggests that aging occurs because cells eventually stop dividing.
This leads to the accumulation of senescent cells that contribute to the aging process.
The “ultimate Hayflick limit” for humans is estimated to be around 125 years.
Beyond this, no amount of lifestyle changes or medical interventions can extend the human lifespan.
Hayflick’s discovery has been applied to cells from various animals, revealing different Hayflick limits based on species’ lifespans.
Ex. Galapagos turtles, have cells that can divide approximately 110 times, whereas laboratory mice have a much lower limit of around 15 divisions.
Broader Implications and Research
Hayflick’s discovery led to the discovery of telomeres in the 1970s.
Telomeres are protective DNA sequences at the ends of chromosomes, which shorten with each cell division.
When telomeres reach a critical length, cell division stops, which correlates with the Hayflick limit.
In the 1980s, scientists discovered telomerase, a protein capable of replenishing telomeres, which is naturally active in cancer cells, allowing them to bypass the Hayflick limit.
