    Biologics & Biosimilars: The next frontier in Affordable Medicines

    Why in the News?

    While most medicines are small molecule drugs with simple structures, a newer class—biologics and biosimilars—is reshaping modern medicine with their complex, targeted action.

    What are Small Molecule Drugs?

    • Definition: Chemically synthesised, low molecular weight compounds.
    • Features: Fixed structure, chemically stable, easy to replicate, patent-protected.
    • Cost Dynamics: Expensive while under patent; affordable generics post-expiry (e.g., Sovaldi dropped from $84,000 to $1,000).

    About Biologics & Biosimilars:

    • Biologics-
      • Overview: Large, complex drugs made from living cells or organisms.
      • Examples: Insulin (~5,800 daltons), Remicade (~150,000 daltons).
      • Nature: Slight structural variations possible; used for cancer, autoimmune diseases, hormone therapy.
    • Biosimilars-
      • Overview: Near-identical versions of biologics, made after patent expiry.
      • Not Generics: Due to complex cell-based production, they’re similar but not identical.
      • Use: Offer lower-cost alternatives to high-end biologics.

    Regulation and Reform:

    • Current Barriers: Biosimilars need costly trials (animal + clinical), unlike generics.
    • Global Moves: UK and USA are easing animal trial norms (organ-on-chip, human models).
    • India: Still follows older norms; waivers under review, but clinical trials still mandatory.

    Significance for India:

    • Access: Generic small molecules transformed Indian healthcare.
    • Opportunity: Affordable biosimilars can do the same for chronic and rare diseases.
    • Urgency: Regulatory reform is key to reduce costs, speed up access, and widen healthcare coverage.
    [UPSC 2020] What is the importance of using Pneumococcal Conjugate Vaccines in India?

  • Surrogacy in India

    Age Cap for Surrogacy in India

    Why in the News?

    The Supreme Court of India has reserved its judgment (i.e. final decision is pending) in a set of petitions challenging the age-related eligibility criteria under the Surrogacy (Regulation) Act, 2021.

    These cases involve couples who had initiated the surrogacy process prior to the enactment of the law on January 25, 2022, but are now disqualified due to the new age limits.

    About the Surrogacy (Regulation) Act, 2021

    • Objective: To regulate surrogacy in India, prohibit commercial surrogacy, and promote ethical, altruistic surrogacy based on medical necessity.
    • Scope:

    Key Provisions:

    • Type Permitted: Only altruistic surrogacy (unpaid surrogate mother) is allowed; commercial surrogacy is banned.
    • Eligibility Criteria for Intending Couples:
      • Legally married for at least 5 years.
      • Woman must be 23–50 years of age; man must be 26–55 years.
      • Must not have any living biological, adopted, or surrogate child.
    • Eligibility for Single Women:
      • Only widows or divorcees between 35–45 years are eligible.
      • Unmarried women are not eligible (currently under challenge).
    • Surrogate Mother Criteria:
      • Must be a close relative, married, and have at least one biological child.
      • Age: 25–35 years.
    • Certification Requirement: A Certificate of Essentiality is required, including:
      • Proof of infertility
      • Court order for parentage and custody
      • Insurance for the surrogate mother
    • Penalties: Commercial surrogacy invites imprisonment (up to 10 years) and fines (up to ₹10 lakh).
    • Regulatory Structure:
      • National Surrogacy Board at the central level.
      • State Surrogacy Boards at the state level.

    Issues Highlighted by the Supreme Court:

    • No Transitional Provision: The Act lacks a grandfather clause to protect couples who began the surrogacy process (e.g., embryo freezing) before the law came into effect in January 2022.
    • Rigid Age Limits: The court questioned the fairness of disqualifying couples solely on age grounds, especially when natural pregnancies at older ages are not prohibited.
    • Violation of Fundamental Rights: Petitioners argued the age restrictions violate Article 14 (equality before law) and Article 21 (right to reproductive autonomy and personal liberty).
    • Exclusion of Unmarried Women: The law permits only widows or divorcees (35–45 years) to pursue surrogacy, which the court noted may be arbitrary and discriminatory.
    • Law’s Intent vs. Impact: The court stressed that while the law aims to prevent commercial surrogacy, it should not unreasonably prevent genuine intending parents from having children.
    [UPSC 2020] In the context of recent advances in human reproductive technology, “Pronuclear Transfer” is used for:

    Options: (a) fertilization of egg in vitro by the donor sperm (b) genetic modification of sperm producing cells (c) development of stem cells into functional embryos (d) prevention of mitochondrial diseases in offspring*

    Piprahwa Relics of Buddha

    About the Piprahwa Relics:

    • Discovery: Unearthed in 1898 by William Claxton Peppe, a British engineer, at Piprahwa (Siddharthnagar, Uttar Pradesh), near the Nepal border.

    • Historical Significance: Identified as ancient Kapilavastu, capital of the Shakya republic, where Prince Siddhartha (Buddha) lived before renunciation.

    • Findings at the Site: A buried stupa yielded a large stone coffer containing:

      • Bone fragments believed to be Buddha’s relics
      • Caskets made of soapstone and crystal
      • A sandstone coffer
      • Over 1,800 ornaments: pearls, rubies, sapphires, gold sheets
    • Legal Custody:

      • The British Crown claimed the relics under the Indian Treasure Trove Act, 1878.
      • Most artifacts were transferred to the Indian Museum, Kolkata.

    Stupas with Buddha’s Relics:

    • After the Buddha’s death (Mahaparinirvana), his cremated relics were divided among 8 kingdoms and a Brahmin named Drona, who coordinated their distribution.
    • Each recipient built a Stupa to enshrine their share of the relics, creating important pilgrimage sites and early centers of Buddhist worship.
    • The 9 stupas were located in Rajagriha, Vaishali, Kapilavastu, Allakappa, Ramagrama, Vethadipa, Pava, Kushinagar, and Pippalivana.
    • Emperor Ashoka (3rd century BCE) redistributed the relics from these stupas into thousands of new stupas across his empire.
    • The stupa at Ramagrama is unique because it is believed to remain untouched and still holds the original relics.
    • A typical early Buddhist stupa included a hemispherical mound (anda), a square railing (harmika), a central pillar (yashti) with umbrellas (chatra), and a path for circumambulation (pradakshinapatha).
    [UPSC 2023] With reference to ancient India, consider the following statements:

    1. The concept of Stupa is Buddhist in origin.

    2. Stupa was generally a repository of relics.
