    NexCAR19: India’s First Indigenous CAR T- Cell Therapy for Cancer

    Why in the news?

    • President Droupadi Murmu has unveiled ‘NexCAR19’ India’s first indigenously-developed CAR T-cell therapy for cancer treatment.

    What is CAR-T Cell Therapy?

    What is it?
    • CAR-T cell therapy stands for Chimeric Antigen Receptor T cell therapy.
    • It is a type of cancer immunotherapy that uses the patient’s own T cells, genetically modified in a laboratory to enhance their ability to locate and destroy cancer cells.
    How does it work?
    • T cells are white blood cells responsible for identifying and fighting illness and infection.
    • Each T cell has a receptor that can recognize antigens (proteins or molecules recognized by the immune system).
    • Cancer cells may have antigens that the immune system does not recognize as abnormal, allowing cancer to evade the immune response.
    • CAR-T cells are genetically engineered in the lab to express a new receptor that can bind to cancer cells and effectively kill them.
    Therapy Process The process involves several steps, including:

    1. Collecting T Cells: Blood is drawn from the patient’s arm, and T cells are separated from the blood using an apheresis machine.

    2. Engineering T Cells: In a laboratory, the T cells are modified by adding a manufactured CAR, and they are allowed to multiply and grow.

    3. Infusing CAR-T Cells: Once enough CAR-T cells are prepared, they are injected back into the patient’s arm.

    • Chemotherapy may be recommended before CAR-T cell infusion to enhance treatment effectiveness.
    • The process can take place in an outpatient infusion center or a hospital setting.
    Cancers Treated
    • CAR-T cell therapy is effective against certain types of cancer, especially when other treatments are ineffective.
    • It is currently FDA-approved for treating haematological malignancies, including leukemia, lymphoma, and multiple myeloma.

     

    NexCAR19: India’s Indigenously Developed CAR-T Therapy

    • NexCAR19 is designed to target cancer cells carrying the CD19 protein, a marker on cancer cells, enhancing precision in treatment.
    • It has been developed jointly by IIT Bombay and the Tata Memorial Centre.
    • Initially approved for patients aged 15 and above with B-cell lymphomas who did not respond to standard treatments, leading to relapse or recurrence.

    Effectiveness and Unique Features

    • Approximately 70% of patients respond to NexCAR19 treatment, with some achieving complete remission.
    • Lab and animal studies indicate lower drug-related toxicities, including reduced neurotoxicity and Cytokine Release Syndrome (CRS).
    • Trials for paediatric patients are underway at Tata Memorial Hospital, ensuring broader applicability.

    Availability and Affordability

    • ImmunoACT is in the process of securing licenses and partnering with hospitals, including Tata Memorial, Nanavati, Fortis, and Jaslok, across multiple cities.
    • Initially priced at Rs 30-40 lakh, ImmunoACT aims to eventually reduce the cost to Rs 10-20 lakh, making the therapy more accessible.

  • Finance Commission – Issues related to devolution of resources

    Should State Governments borrow more? | Explained

    Why in the News? 

    Recently, the SC rejected Kerala’s plea for immediate relief in its case urging the Union government to ease borrowing constraints, allowing the state to secure extra funds in the ongoing fiscal year.

    State governments receive funds from three sources:

    • Own revenues (tax and non-tax)
    • Transfers from the Union government as shares of taxes and as grants 
    • Market borrowings

    Fiscal Demands for Extra Funds: 

    • Increased Expenditure: In 2020-21, the Kerala government sharply increased its spending to 18% of its GSDP, to provide economic relief in the wake of the COVID-19 pandemic, aided by the relaxation in borrowing norms then
    • Central Gov transfers to Kerala declined: As ratios of GSDP, the Union government’s transfers to Kerala declined to 2.8% in 2023-24, significantly lower than previous years, even as the State’s revenues remained at around 8.0%. 
    • This meant that, in 2023-24, the State government could meet its modest budget expenditure, equivalent to 14.2% of GSDP, only by raising the borrowing to 3.4% of the GSDP

    Socio-Economic for Extra Funds: 

    • Aging Population: Kerala, like many other states, faces the challenge of an aging population, which puts pressure on pension funds and healthcare systems, necessitating long-term financial planning and investment.
    • Pension Liabilities: The substantial outgo for pensions poses a financial burden on the state’s budget, requiring strategies for sustainable pension management to ensure fiscal stability.
    • Youth Outmigration: Kerala experiences significant outmigration of its youth, leading to a loss of productive workforce and potential tax revenues, highlighting the need for policies to retain skilled workers and stimulate economic growth

    About Net Borrowing Ceiling (NBC):

    • The net borrowing ceiling for states in India denotes the maximum threshold set on the funds that state governments can borrow within a fiscal year.
    • Significance: Ensuring fiscal discipline and preventing states from accumulating excessive debt, the net borrowing ceiling plays a pivotal role. 
    • Factors: The criteria for setting these limits are shaped by various factors such as inputs from the Finance Commission, the Fiscal Responsibility and Budget Management (FRBM) Act, and specific directives from the central government, notably the Ministry of Finance.

     

    Basis of the Net Borrowing Ceiling:

    • Fiscal Responsibility Legislation: Both the central and state governments in India adhere to the FRBM Act, which establishes fiscal deficit goals to uphold fiscal discipline. Under the FRBM, states are required to maintain a fiscal deficit limit of 3% of the Gross State Domestic Product (GSDP).
    • Central Government Guidelines: The central government, through the Department of Expenditure in the Ministry of Finance, sets the annual borrowing limits for each state based on a formula that considers the state’s GSDP, existing debt levels, fiscal discipline, and other relevant factors. These limits can be revised in response to special circumstances, such as natural disasters or significant economic downturns.
    • Finance Commission Recommendations: The Finance Commission, which is constituted every five years, recommends how the central taxes are to be divided between the centre and the states and suggests measures to maintain fiscal stability. It also provides recommendations regarding the borrowing limits of states.

    Conclusion: States need to put in place an effective forecasting and monitoring mechanism for cash inflows and outflows so that a need-based approach is followed for market borrowings and the interest cost of cash surpluses is minimized.

  • Nuclear Energy

    Nuclear power is key to development, says study

    Why in the news? 

    A recent report published by  IIM-A suggested that India must prioritize investment in Nuclear energy sector and expand related infrastructure.

    Why India must prioritize investment in the Nuclear energy sector?

    India aims to be a developed country by 2047 and is on track to achieve net zero — or effectively zero-carbon dioxide emissions by 2070. 

    Key findings of the Report: 

    • Current Energy Mix: Solar energy constitutes 16% of India’s installed generation capacity, while coal comprises 49%. Nuclear energy currently comprises only 1.6% of India’s energy mix
    • Significant increase in nuclear power: The best-case scenario shows emissions falling to 0.55 billion tonnes of carbon dioxide by 2070, achieving ‘net zero’. This scenario entails a significant increase in nuclear power capacity, reaching 30 GW by 2030 and 265 GW by 2050.
    • Investment Requirements for Nuclear Energy: Achieving the proposed figures for nuclear energy would necessitate a doubling of investments. India would require an estimated ₹150-200 lakh crore between 2020-2070 to finance the necessary transitions in the energy sector
    • Need technology-based solution: The authors emphasize that achieving net zero emissions requires a combination of technologies rather than a single solution.
    • Transitioning away from coal: Coal is expected to remain a significant component of India’s energy system, serving as the “backbone”. However, transitioning away from coal would require substantial investment  

    What are the Challenges for India’s Goal of Net-Zero Emissions?

    • Uranium Factor: Data by the Central Electricity Authority say solar energy accounts for 16% of India’s installed generation capacity. To achieve these idealistic figures for nuclear energy would require a doubling of investments as well as the assumption that uranium, a critical fuel but restricted by international embargo, is available in necessary quantities.
    • Coal Factor: Coal accounts for 49% of India’s capacity. Coal would likely be the “backbone” of the Indian energy system and if the country has to phase down coal in the next three decades, it would need to build adequate infrastructure for alternative sources such as nuclear power, in addition to flexible grid infrastructure and storage to support the integration of renewable energy.

    Suggested measures by the Report are:

    • Research and Development: Invest in research and development to improve efficiency and reduce costs of renewable energy technologies, as well as advancements in nuclear energy technology.
    • Policy Support: Implement supportive policies and regulations to encourage private sector investment in the energy sector, including streamlined approval processes, tax incentives, and renewable energy mandates.
    • International Cooperation: Engage in diplomatic efforts to secure access to nuclear fuel and address international embargoes, while also collaborating with other countries on research and development in the energy sector.

    Conclusion: India’s path to development by 2047 hinges on prioritizing energy sector investment, as per an IIM-A report. Achieving net zero emissions by 2070, India would need close to ₹150-200 lakh crore between 2020-2070 to finance these transitions.

  • Right To Privacy

    Living wills implementation lags in India

    Why in the news? 

    In early March this year, 30 people in Thrissur in Kerala executed living wills.

    Context:

    • The Supreme Court’s 2018 order on Passive Euthanasia, wherein it recognized the ‘Right to die with dignity’ as a fundamental right and an aspect of Article 21 (right to life) of the Constitution.
    • However, the people wanting to get a “living will” registered were facing problems due to cumbersome guidelines, prompting a reconsideration by the apex court.
    • A Constitution Bench, led by Chief Justice of India Dipak Misra, in three concurring opinions, upheld that the fundamental right to life and dignity includes the ‘Right to Refuse Treatment and Die with dignity’.

    What is a Living Will? 

    A Living Will is a healthcare directive, in which people can state their wishes for their end-of-life care, in case they are not in a position to make that decision.

    The Court’s procedure:

    • Pre-2023: Initially, the process of creating living wills was deemed overly complex by the Court, with elaborate bureaucratic procedures in place to prevent abuse by unscrupulous individuals seeking to exploit the patient’s assets.
    • Post-2023: Recognizing the impracticality of requiring judicial magistrate countersignatures on living wills, the Court streamlined the process in January 2023. Now, living will require signatures in the presence of witnesses, attestation by a notary or gazetted officer, and submission to a designated government officer acting as a custodian.

    Challenges in Implementation :

    • Decision-Making Process: Even if a living will is created, its implementation is not automatic. Decisions on withholding or withdrawing treatment require certification by primary and secondary medical boards, posing logistical challenges, especially in hospitals without designated boards.
    • Ambiguities and Discomfort: Ambiguities in guidelines, discomfort with end-of-life care topics, and unclear legal definitions contribute to the hesitancy among officials to implement the Court’s directives without clear instructions from higher authorities.
    • Legal Ambiguity: Indian law lacks a clear definition of ‘next of kin’, leading to potential disputes among family members about medical decisions for terminally ill patients.
    • Barriers to End-of-Life Decisions: A survey of intensive care doctors reveals a general belief that end-of-life decisions are fraught with legal implications, serving as a significant barrier to making such decisions in the ICU.
    • Regional Disparities in India:
    • Haryana: While some states like Haryana have issued directions to follow the judgment, they have not provided essential guidance or protocols for implementation.
    • Odisha: In contrast, Odisha has taken a more thorough approach by forming a committee of experts to develop detailed draft orders for implementing the judgment, setting a potential example for other states.

    Conclusion: The central government could help bridge the gap in expertise by developing and publishing model orders and protocols to provide states with confidence and guidance in effectively implementing the judgment.

  • Global Geological And Climatic Events

    Taiwan’s Earthquake and the Pacific Ring of Fire

    Why in the news?

    • Taiwan was struck by its most powerful earthquake in at least 25 years.
    • Its susceptibility to earthquakes is attributed to its location along the Pacific “Ring of Fire” where a majority of the world’s seismic activity occurs.
    • Taiwan is primarily influenced by the collision of the Philippine Sea Plate and the Eurasian Plate.

    What is the Pacific ‘Ring of Fire’?

    • The Pacific ‘Ring of Fire’ or Pacific Rim, or the Circum-Pacific Belt, is an area along the Pacific Ocean that is characterized by active volcanoes and frequent earthquakes.
    • Volcanic arcs and oceanic trenches partly encircling the Pacific Basin form the so-called Ring of Fire.
    • It is home to about 75 per cent of the world’s volcanoes – more than 450 volcanoes.
    • Also, about 90 per cent of the world’s earthquakes occur here.

    Its spread

    • Its length is over 40,000 kilometres and traces from New Zealand clockwise in an almost circular arc covering Tonga, Kermadec Islands, Indonesia.
    • It is moving up to the Philippines, Japan, and stretching eastward to the Aleutian Islands, then southward along the western coast of North America and South America.

    Seismic activity of the region

    • The area is along several tectonic plates including the Pacific plate, Philippine Plate, Juan de Fuca plate, Cocos plate, Nazca plate, and North American plate.
    • The movement of these plates or tectonic activity makes the area witness abundant earthquakes and tsunamis every year.
    • Along much of the Ring, tectonic plates move towards each other creating subduction zones.
    • One plate gets pushed down or is subducted by the other plate.
    • This is a very slow process – a movement of just one or two inches per year.
    • As this subduction happens, rocks melt, become magma and move to Earth’s surface and cause volcanic activity.
