  • Synthetic Compounds: While many antibiotics are derived from natural sources, synthetic antibiotics have also been developed in the laboratory. These compounds are designed to mimic the properties of natural antibiotics and can offer benefits such as increased stability and targeted action.

An Age Old Market, Facing Challenges in this Era

Antimicrobial Resistance: A Growing Concern

Antimicrobial resistance (AMR) happens when bacteria, viruses, fungi, and parasites change and adjust to the drugs meant to eliminate them. This phenomenon is primarily driven by the misuse and overuse of antibiotics in healthcare, agriculture, and other sectors. The rise of multi-drug-resistant bacterial infections poses a significant threat to global health, as it reduces the usefulness of antibiotics and can lead to prolonged illnesses, increased mortality rates, and higher healthcare costs. The World Health Organization (WHO) has been actively working to address the challenge of antimicrobial resistance by promoting responsible antibiotic use, encouraging the development of new antibiotics, and advocating for increased awareness. However, the problem persists, with multi-drug-resistant bacterial infections becoming more common and difficult to treat.

Besides this, there is a growing emphasis on antimicrobial stewardship programs. These programs aim to optimize the use of antibiotics by promoting responsible prescribing, improving diagnostics, and encouraging patient education. The development of rapid diagnostic technologies is a promising trend, enabling healthcare providers to identify bacterial infections and tailor treatment strategies more precisely.

Shortages of Critical Antibiotics: Causes and Implications

In recent years, there have been concern related to the shortages of critical antibiotics such as penicillin and amoxicillin. This penicillin shortage and amoxicillin shortage have raised alarms within the medical community, as they hinder the capability to offer appropriate and effective treatments for bacterial infections.1 , 2
The shortages are attributed to various factors, including supply chain disruptions, manufacturing challenges, regulatory hurdles, and the financial viability of producing certain antibiotics. The relatively low profitability of antibiotics further exacerbates these challenges compared to other pharmaceutical products, which has led some pharmaceutical companies to scale back or discontinue antibiotic production.

Addressing the Challenges: A Comprehensive Approach

A comprehensive approach is necessary to tackle the antibiotics market challenges. This includes efforts to promote responsible antibiotic use among healthcare providers and the general public, incentivize the development of new antibiotics through policy changes and financial incentives, and improve manufacturing and supply chain resilience to prevent shortages. Furthermore, collaboration between governments, pharmaceutical companies, healthcare organizations, and international bodies is crucial to developing a coordinated global strategy to combat antimicrobial and antibacterial resistance and ensure a stable supply of critical antibiotics.

Exploring the Field of New Antibiotics

How Many New Antibiotics are in the Pipeline?

The antibiotics market has historically been a crucial sector in the pharmaceutical industry, contributing to the overall improvement of global healthcare. The discovery of antibiotics marked a turning point in medicine, effectively treating once-deadly infections and significantly extending the human lifespan. Over the years, the antibiotics market has witnessed remarkable advancements, with various classes of antibiotics developed to target different types of bacteria. Multiple antibiotics have been approved for the prevention / treatment of various infectious diseases, including urinary tract infection and skin infection, caused by gram negative as well as gram positive bacteria since 1980. Further, in the last eight years, developers have received approvals for more than 25 new antibiotics intended for the treatment of multiple infectious diseases. It is worth highlighting that over 150 antibiotics are currently being evaluated in different stages of preclinical / clinical development, either as monotherapies or combination therapies. Additionally, over 1,720 clinical trials are evaluating various new antibiotics to fight antimicrobial resistance. The preclinical pipeline of antibiotics includes more diverse and novel candidates; however, it is likely to take up to 10 years for these new antibiotics to reach the market.

Why Large Pharmaceutical Companies are Abandoning New Antibiotics Research

New antibiotics development requires huge amounts of money, however, pharmaceutical companies are failing to recover their costs or make a profit. Over years, many promising antibiotic candidates have failed along the way. It is worth highlighting that, for existing classes of antibiotics, only one out of every 15 antibiotics in preclinical development reaches the market. For novel antibiotic classes, only one out of every 30 antibiotic candidates reached the patients. Further, new antibiotics are considered as drugs of last resort against dangerous bacteria. Therefore, these new antibiotics are sparingly used to limit the development of antibiotic resistance and are not sold in large volumes. Additionally, antibiotics bear lower price as compared to more expensive treatments. As a consequence, many large pharmaceutical companies have started to pull out of the antibiotic market due to the low price limits and low sales of antibiotics. In 1980s, there were 18 multinational companies committed to antibiotic research; today there are only a handful.

Presently, antibiotic R&D is primarily driven by small pharmaceutical companies. In recent years, small pharma companies have made some exciting scientific breakthroughs. Many of these companies have been funded through initiatives such as CARB-X – a partnership between governments and philanthropic organizations like Wellcome – through what is called ‘push’ funding.
