FDA Approved Drugs: October, 2022

Imjudo (tremelimumab)

AstraZeneca’s Imjudo (tremelimumab) was approved by FDA in combination with Imfinzi (durvalumab) for treating unresectable liver cancer. HCC is the most common type of liver cancer.

Imjudo (tremelimumab) is a human monoclonal antibody that targets the activity of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). Imjudo blocks the activity of CTLA-4, contributing to T-cell activation, priming the immune response to cancer and fostering cancer cell death.

The approval was based on positive results from a Phase III trial (HIMALAYA), which demonstrated that patients treated with the combination of Imjudo and Imfinzi experienced a 22% reduction in the risk of death compared to sorafenib, an oral kinase inhibitor used to treat late-stage liver cancer. The results of the Phase III trial also showed evidence that the combination therapy allowed an estimated 31% of patients to live three years after administration, compared to 20% of sorafenib-treated patients, who showed the same longevity.

Beyond HIMALAYA, Imjudo is being tested in combination with Imfinzi across multiple tumour types including locoregional HCC (EMERALD-3), SCLC (ADRIATIC) and bladder cancer (VOLGA and NILE).

Imjudo is also under review by global regulatory authorities in combination with Imfinzi and chemotherapy in 1st-line metastatic NSCLC based on the results of the POSEIDON Phase III trial, which showed the addition of a short course of Imjudo to Imfinzi plus chemotherapy improved both overall and progression-free survival compared to chemotherapy alone.

Tecvayli (teclistamab-cqyv)

Janssen’s Tecvayli (teclistamab-cqyv) is a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager indicated for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 monoclonal antibody.

  • Multiple myeloma is a cancer of the plasma cells in the bone marrow. Plasma cells normally make antibodies which fight infection, but when the plasma cells become malignant and develop into multiple myeloma, the myeloma cells proliferate and replace normal cells in the bone marrow.
  • Tecvayli targets both BCMA (B-cell maturation antigen) and CD3, the T-cell receptor. BCMA is expressed at high levels on multiple myeloma cells. Tecvayli works by redirecting CD3-positive T-cells to BCMA-expressing myeloma cells to induce the killing of the cancer cells.
  • Warnings and precautions associated with Tecvayli include hepatotoxicity, infections, neutropenia, hypersensitivity and other administration reactions, and embryo-fetal toxicity.
  • Common adverse reactions observed in clinical trials include cytokine release syndrome, neutropenia, and anemia. Infections were frequent with the most common being upper respiratory tract infections and pneumonia. Hypogammaglobinemia and neurotoxic events were also observed in some patients.

Impact of Coronavirus (COVID19) on India Pharmaceuticals

Impact of Coronavirus (COVID19) on India Pharmaceuticals

India is one of the largest providers of generic drugs worldwide. India pharmaceutical industry supplies approximately 50% of vaccines worldwide, 40% of generics in the United States and 25% of all medicines in the United Kingdom. India exports bulk drugs, intermediates, drug formulations, biologicals, Ayush & herbal products, and surgicals to various countries.

According to the India Brand Equity Foundation (IBEF), the Indian pharmaceutical sector had a market size of USD 33 Billion in 2017. India’s pharmaceutical exports had witnessed an increase from USD 19.14 Billion in 2019 to USD 17.27 billion in 2018.

The novel coronavirus (COVID-19) outbreak had a negative impact on the India pharmaceutical industry in the following ways:

  • India has restricted the export of several drugs such as paracetamol, antibiotics such as tinidazole and erythromycin, hormone progesterone, which is used in the contraceptive pill, and vitamins B12, B1 and B6. These drugs account for approximately 10% of all India’s pharmaceutical exports.
  • The Indian government have imposed limits on the export of 26 pharmaceutical ingredients
  • Indian pharmaceutical companies are now close to exhausting their supply of raw materials such as active pharmaceutical ingredients (APIs). Moreover, the inventories related to the pharmaceutical ingredients are running low.
  • Several pharmaceutical companies who have contracts with domestic clients and various state governments to supply medicines have been crippled, as manufacturing has come to a halt due to a shortage of raw materials from China
  • Pharmaceutical companies are not able to procure pharmaceutical ingredients for Mintelukast, used for asthma, pain medication Nimesulide, and Amoxicillin, Ofloxaicin, and Chloramphenicol, which are used to treat bacterial infections, and antibiotic Metronidazole
  • Small and medium companies have been most  affected as they depend on traders and keep lower inventory
  • There is a drastic increase of 20-30% in the prices of raw materials used in medicines like Amoxicillin and Paracetamol.
  • The pharmaceutical logistics is facing the difficulties in receiving the raw material from other parts of the country
