Since then, antibiotics have become one of the most common classes of drugs – used to prevent and treat infections, and make possible complex surgeries that have become routine, from caesarean sections to hip replacement surgeries and organ transplants.

But antibiotics are not as effective as they used to be. Over time certain bacteria, so-called ‘superbugs’, have adapted and learned to resist the effects of the drugs designed to kill them.

Our collective overuse of antibiotics – in humans, animals and plants – has accelerated this process.

Today, drug-resistant infections are a serious threat to people’s health. Hundreds of thousands of lives are lost every year because of infections that can no longer be treated with existing drugs.

Discovering new antibiotics, able to kill drug-resistant bacteria, is essential to saving modern medicine.

But that’s only part of the solution, as over time bacteria will learn to resist the new drugs too. To stay ahead of the game in this constant race against superbugs, we also need innovations in developing vaccines and diagnostics, and better prevention control and surveillance.

No new classes of antibiotics have been discovered since the 1980s. A class defines a group of antibiotics that have a certain way of working – for example by killing bacteria or by stopping them multiplying – and are effective

Discovering and developing genuinely new antibiotics is challenging: the science is tricky and the research and development process is time-consuming and expensive, and often fails.

It can take 10-15 years and over $1billion to develop a new antibiotic.

Stages of antibiotic research and development (R&D) The discovery process starts with basic research to identify organisms that produce antibiotic substances (sometimes in surprising places, such as the Komodo

While it’s easy to find substances that kill bacteria, it’s much more difficult to discover and develop substances that are not also toxic to humans.

Promising candidates found in pre-clinical development move into clinical trials, where the new drugs are tested to see if they’re safe and effective in people.

Clinical trials, which usually run in three phases, are even more expensive and complex. They require resources, infrastructure and expertise that can only be provided by large pharmaceutical companies. The final phase of trials – and the trials needed after an initial product launch – can account for more than 80% of the total R&D spend on a new drug. If a new drug proves safe and effective, it needs to be registered with a government drugs regulator before being legally prescribed in a country.

The approval process, which tends to be slow and full of regulatory hurdles, adds to the costs and the timeline.

Despite these efforts, it can be very difficult to get doctors and health systems to buy and use new antibiotics. And, as the last line of treatment against certain infections, they need to be used sparingly to limit the development of drug resistance. The current economic model for developing new antibiotics is failing. Companies invest huge amounts of money to bring a new drug to market but cannot recover their costs or make a profit. "This is the only field within pharmaceutical science where you come out with a drug and you don’t want it to be used too much," explained Anand Anandkumar, CEO of Bugworks, a biopharma start-up dedicated to discovering new antibiotics.

New antibiotics are seen as ‘drugs of last resort’ against dangerous bacteria.

So, to limit the development of antibiotic resistance, they need to be used sparingly – and not sold in large volumes. Plus, compared to more expensive treatments, antibiotics tend to be quite low in price.

The combination of low sales and low prices limits the amount of money companies can make.

Without financial incentives, many large pharmaceutical companies have started to pull out of the field. In the 1908s there were 18 multinational companies committed to antibiotic research; today there are only a handful.

Antibiotic R&D is now primarily driven by small biotechnology companies.

In recent years, they have made some exciting scientific breakthroughs. Many have been funded through initiatives such as CARB-X – a partnership between governments and philanthropic organisations like Wellcome – through what is called ‘push’ funding.

A scientific breakthrough doesn’t guarantee success though, as much more funding is needed to see drugs through the expensive process of clinical trials, registration and coming to market. Once companies

Many of these will only bring limited benefits compared to existing treatments. And only a few target Gram-negative bacteria, which are the most dangerous resistant bacteria and can cause severe infections like pneumonia, bloodstream infections or meningitis.

The pre-clinical pipeline includes more innovative and diverse candidates – over 250 antimicrobial agents are in early-stage testing.

But it will take up to 10 years for the first of these drugs to make it to market. And many promising candidates will fail along the way.

For antibiotics in existing classes, on average, only one for every 15 drugs in pre-clinical development will reach patients. For new classes of antibiotics, only one for every 30 candidates.

With large pharmaceutical companies continuing to abandon antibiotic research, small and medium-sized companies now dominate the space – they account for around 90 percent of the new antibiotics in development.

But they face formidable challenges in trying to bring new drugs to market and making them accessible. Innovation also comes from not-for-profit organisations – pretomanid, which was recently approved for patients with highly drug-resistant forms of tuberculosis, was developed by TB

While non-traditional development pathways are valuable, strengthening the

Industry, governments and philanthropic organisations need to work together to ensure a sustainable pipeline of new drugs. One is implementing a system of 'market entry rewards' – giving lump-sum payments to successful developers of new antibiotics, as first suggested in Jim O’Neill’s report. Another idea is a ‘subscription’ style payment model, which the UK government announced it will be piloting. This involves paying pharmaceutical companies upfront for access to drugs based on their usefulness to the NHS.

Other interventions have proposed treating antibiotics as a global good, for example, by governments stockpiling antibiotics as they do with emergency medicines.

These solutions will require significant investment from governments, and the commitment has been low so far.

Among the pharmaceutical companies that have remained committed to antibiotic R&D, some have started to change their practices, for example by: removing financial bonuses tied to sales, sharing data on the spread of drug-resistant infections and putting plans in place to ensure better access to new antibiotics.

While these trends are encouraging, change is not happening at the scale required.

The global community needs to respond quickly to make sure we protect modern medicine against the increasing threat of drug-resistant infections while there is still time. New partnership models which share risk, resources and expertise across philanthropies, industry and the public sector could provide answers.

UNICEF is working in partnership with WHO and other stakeholders to accelerate child pneumonia mortality declines by advancing WHO prequalification for the medicines used to treat pneumonia, including Amoxicillin dispersible tablets.

Pneumonia is the leading cause of infectious disease death among children under five.

Over 920,000 children died from pneumonia in 2016, accounting for 16 percent of all child deaths under five years of age.

The high burden of childhood pneumonia deaths belies the fact that pneumonia-related mortality is preventable with simple interventions and appropriate treatment.

WHO recommends Amoxicillin for the treatment of childhood pneumonia, preferably in child-friendly dispersible tablet (DT) formulation. Despite these recommendations, only roughly one-third of pneumonia cases receive antibiotics as part of the treatment regimen, and even when antibiotics are available, the full course of antibiotics is not consistently taken.

Lack of knowledge amongst caregivers and healthcare providers in terms of dosage, preparation and administration of Amoxicillin DT as well as

The project’s goal is to increase the correct utilization of the Amoxicillin treatment regimen which is dependent on an understanding of how to take the medication as prescribed.

To increase the capacity of community based caregivers and health care providers (HCP) to prescribe and dispense appropriate treatment for childhood pneumonia, UNICEF and PATH have developed a job aid (JA) and user-friendly product presentation (PP) for Amoxicillin DT.

The JA and PP designs included consultation with a designer, manufacturers, and key stakeholders in the Amoxicillin supply chain. Caregivers and HCP need to have a clear understanding of how to administer Amoxicillin DT to children including the dosage, frequency and timing of treatment as well as preparation.

Job aids and clear instructions for medication can facilitate better treatment adherence and when used by HCP, job aids can improve performance, promote compliance with standards and recommendations and reduce the costs of training and re-training.

Medicine labels using pictograms have also been shown to improve understanding of and adherence to treatment regimens among patients and caregivers.

Prior to the roll-out of the adherence aids, a qualitative study was conducted in Zimbabwe, Niger, the Solomon Islands and Bolivia to assess their acceptability, usability and feasibility. Across the four countries, knowledge of pneumonia was persistently poor amongst caregivers, yet they demonstrated an overtly positive response to the product presentations, which they regarded as being highly relevant, acceptable and beneficial in reinforcing how Amoxicillin should be administered to children.
