NovaLead Pharma, the Pune-based company which is into drug repurposing, has received ‘in principal’ clinical trial permission from Drug Controller General of India (DCGI) for its repurposed drug discovery candidate to treat moderate novel coronavirus, or COVID-19.

This approved drug, codenamed NLP21, is in human use for several years for its original use without any side effects of concern. NovaLead is tight-lipped about naming the drug. It says that the drug is readily available off the shelf and therefore there is a risk that public may try to consume it even before the clinical trial is completed.

"In a comparable viral assay study conducted by reputed laboratories in South Korea and United States, NLP21 has shown better viral inhibition ability than Remdesivir, Fevipiravir, Hydroxychloroquine, Lopinavir/Ritonavir etc," the company said.

All these drugs at some point or the other have been considered as probable treatments for COVID-19, but their clinical outcome is as yet inconclusive.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
