Introduction

  • The evolution of drug development are gaining attention. This shift is driven by changing needs of the population, increasing scientific knowledge, and advances in technology.
  • An indepth understanding of the evolving nature of drugs can greatly contribute to the current and ongoing research advancements in the health domain and carefully guide the government in making efficient health policies.
  • The dataset of interest was collected by the European Medicines Agency and contains 1988 rows and 28 columns, including numerical and categorical variables.
  • With our dataset, we will be answering two questions:
    1. What COVID vaccines has undergone the most revisions while maintaining approved authorization status?
    2. What are the recently released medicine for Hepatitis B?

Question 1:

Which COVID vaccines have undergone the most revisions while maintaining an approved authorization status with no conditions applied?


Answering question 1 requires the use of the following variables:

Column Name Description
medicine_name The brand name of the medicine
therapeutic_area The therapeutic area for which the medicine is authorized
authorisation_status The authorization status of the medicine
conditional_approval Indicator if conditional approval is applied
revision_number The number of revisions for the medicine

Approach


1. Filtered the dataset to include only COVID vaccines based on ‘therapeutic_area’ variable.

2. Excluded medicines with conditions applied in the ‘conditional_approval’ variable.

3. Sorted the dataset based on the ‘revision_number’ in descending order to get the vaccines with the most revisions.

4. Extracted and displayed the relevant columns (‘medicine_name’ and ‘revision_number’) for the vaccines.

Top 10 COVID vaccines with the most revisions

  • The analysis reveals that among COVID vaccines with approved authorization status and no conditions applied, RoActemra has undergone the most revisions, followed by Comirnaty and Spikevax (previously COVID-19 Vaccine Moderna), with revision numbers of 40, 38, and 35 respectively.

Question 2:

What are the most recently released medicines (name and company) authorized for human usage for ‘Hepatitis B’?


Answering question 2 requires the use of the following variables:

Column Name Description
category The category (human or veterinary) of the medicine
medicine_name The brand name of the medicine
therapeutic_area The therapeutic area for which the medicine is authorized
authorisation_status The authorization status of the medicine
company_name The company holding the marketing authorization for the medicine
revision_date The date of the latest revision for the medicine

Approach


1. Filtered the dataset to include only medicines related to ‘Hepatitis B’ in the ‘therapeutic_area’ variable.

2. Filtered the dataset to include only medicines for humans in the ‘category’ variable.

3. Sorted the dataset based on the ‘revision_date’ in descending order to get the most recently revised medicines.

4. Extracted and displayed the relevant columns (‘medicine_name’ and ‘marketing_authorisation_holder_company_name’) for the most recently revised medicines.

The latest Hepatitis medicines approved for human use

  • The most recently released medicines authorized for human usage for Hepatitis B are Vaxelis by MCM Vaccine B.V. approved in February 2023. Hexacima and Hexyon, both approved in January 2023. This highlights ongoing efforts in pharmaceutical research to combat Hepatitis B through the introduction of new medications.

Limitations:

  • As our project is focused on current datasets encompassing drugs for COVID and hepatitis B, we can think of utilizing ML models for predicting future changes in drugs.

  • For COVID-19, we are focusing on medicine which have undergone most revisions but this doesn’t necessarily tell us about their quality or level of advancement.
