The total global anti-infective market is currently estimated at $25 billion, and it is
expected to grow in the next few years. From 1999-2004 a number of patents on leading
antibacterial products will expire, making the marketplace highly competitive. In
addition, the continuing increase in antimicrobial drug resistance and the emergence of
new pathogens underline the need for new agents. It is essential that all companies
involved in the anti-infective market are prepared for these developments.
The Complete Guide to Anti-infectives provides all the information you need to address
both current and future market trends. It is written by Gerry Halls, a leading expert with
over 13 years experience in the anti-infective field, which included his creation of the
IMS Hospital Anti-Infective Audit.

EXECUTIVE SUMMARY
ES.1 Introduction
Resistance is probably the most important issue in antimicrobial chemotherapy. Although
'superbugs' have been headline stories in the lay media, the inexorable advance in
resistance in community pathogens, as well as nosocomial pathogens, is driving the
development of new antimicrobials, but also leading to pressures to restrain prescribing.
The research pipeline that will reach the market in the next 2-5 years is, for the most
part, composed of new products from existing classes of antibiotics, antifungals and
antivirals. This will put pressure on the current market leaders, only some of which are
facing patent expiry in that time frame. It will also make the task of successfully
introducing the later-entry products even more challenging as possibilities for product
differentiation are anticipated by the earlier entrants.
The future generations of antimicrobials will be directed at targets identified by
genomics and will avoid cross-resistance with existing classes, but in the short term, the
spectre of untreatable infection - effectively a return to the pre-penicillin era for some
infections - is still a possibility. This, together with efforts to constrain costs, has
led to the development of treatment guidelines which may become treatment protocols,
making product differentiation and inclusion in formularies and guidelines even more
important and challenging.
ES.2 Bacterial infection, resistance and treatment guidelines
Resistance that has recently emerged raises the prospect of a return to the pre-antibiotic
era. Chapter 2 reviews the important bacteria involved. These include staphylococci
(especially methicillin-resistant Staphylococcus aureus (MRSA), streptococci (especially
Streptococcus pneumoniae in meningitis) and enterococci among the Gram-positive bacteria.
The Gram-negative bacteria of medical importance include Pseudomonas aeruginosa,
Stenotrophomonas maltophilia, Acinetobacter and Enterobacteriaceae, implicated with
resistance to extended spectrum cephalosporins in intensive care units (ICUs), together
with Haemophillus influenzae and Escherichia coli, which are involved with infections in
the community.
The relatively recent recognition of the bacteria responsible for atypical pneumonia -
Legionella pneumophilia, Chlamydia pneumoniae and mycoplasmas - has led to the updating of
guidelines on the treatment of community-acquired pneumonia (CAP). Other guidelines
evolving in response to epidemiology, outcomes measures and the trials of new agents, as
well as post-marketing data, include the management of fever in neutropaenic patients.
Guidelines to reduce inappropriate use of glycopeptides (vancomycin and teicoplanin) have
only been partially successful.
ES.3 The antibiotic pipeline
Although the 1980s was the decade of the cephalosporins, the 1990s have been the decade of
the quinolones, in terms of both market growth and R&D activity, a pattern expected to
continue through to 2002. The sequence starting with Levaquin (levofloxacin), Raxar
(grepafloxacin) and Trovan (trovafloxacin) will be closely followed by Bayer's Avelox
(moxifloxacin, the first of the 8-methoxy quinolones, which is being launched relatively
close to the patent expiry of ciprofloxacin), SmithKline Beecham's Factive (gemifloxacin),
Parke-Davis's clinafloxacin, Bristol-Myers Squibb's Tequin (gatifloxacin) and Daiichi's
sitafloxacin.
After an interval of three years, it is likely that the novel quinolone, T-3811, will be
the first to be licensed for paediatric use, followed by Daiichi's DC-756 towards the
middle of the next decade, which has activity against quinolone-resistant bacteria
(including ciprofloxacin-resistant MRSA).
Perhaps the most eagerly awaited antibiotics are the new Gram-positive agents active
against MRSA and vancomycin-resistant enterococci (VRE): Rh�ne-Poulenc Rorer's Synercid,
Pharmacia & Upjohn's Zyvox (linezolid) and Schering-Plough's everninomicin, Ziracin.
Chapter 3 covers the antibiotic classes by therapy class sequence, including the new
peptide antibiotics that suffered a setback when the US Food and Drug Administration (FDA)
declined to approve Magainin's Locilex (pexiganan acetate) for diabetic ulceration. This
situation is likely to be only temporary, however, as Xoma's Neuprex is in Phase III
trials as monotherapy for meningococcal sepsis. Some of the new targets for antibiotics
are also explored, including the novel bacterial signalling, termed quorum sensing.
ES.4 The antifungal market
In fungi, the problem of resistance is principally intrinsic. Chapter 4 covers the main
pathogenic fungi and the infections they cause, from skin infections to the emerging
moulds that are causing fatal infections in heavily immunosuppressed patients. The
development pipeline is heavily biased towards more active and broader-spectrum triazoles,
which will be competing with the lipid formulations of amphotericin B in the most severe
infections, and with the existing triazoles for the increasingly prevalent,
less-susceptible, non-Candida albicans species. The new category of cell wall-active
fungicidal agents is led by Merck & Co's pneumocandin. This may be the first
well-tolerated cidal agent that does not act on the fungal cell membrane. These
introductions may place further pressure on the lipid formulations of amphotericin B,
which are restricted to refractory patients and those with failing renal function due to
cost issues. Health economic studies examining total costs are also reviewed.
ES.5 The antiviral market
In terms of market size, as well as classification, the antiviral market can be divided
between HIV and other viral infections. Chapter 5 describes the most important viruses,
the infections they cause - for which antiviral drugs are marketed or are in development -
and treatment guidelines. The development of resistance, especially class resistance, is
more problematic than for antifungals. This has been well publicised with the durability
of effect of current antiretrovirals used to treat HIV.
Toxicity is even more of a concern when treating viral rather than fungal infections, as viruses rely on host cell metabolic processes for their replication cycle. This is demonstrated for example by the appearance of lipodystrophy and other metabolic disorders associated with protease inhibitors, which only three years ago (1996) at the 11th International AIDS Conference were being described as possibly curative. Treatment protocols have been reassessed. These are reviewed, together with pipeline HIV products, including those for new targets.
Among the developments for viral infections other than HIV are treatments for hepatitis B
virus, which has a target similar to HIV and for which the first HIV antiretroviral for
hepatitis B - lamivudine - will soon be introduced as Zeffix by Glaxo Wellcome. New
targets specific to hepatitis B virus are further away but the market potential is
considerable as so many chronic carriers of hepatitis will develop fibrosis and cirrhosis.
Hepatitis is one of the leading causes of liver transplantation, and an even larger number
of chronic hepatitis patients are carriers of hepatitis C.
This virus is an RNA virus, and while specific agents are being developed, these are further away. Also in development with potentially even larger patient populations are treatments for influenza, which are close to marketing, and the common cold. These will have implications for healthcare resources leading to likely increases in patient co-payments.
ES.6 Pharmacokinetics, pharmacodynamics and evolving regulatory requirements
Pharmacokinetics and pharmacodynamics have now come of age. Chapter 6 discusses the main
aspects that are being incorporated into development programmes and into pre-marketing
communications to demonstrate competitive advantage where, previously, minimal inhibitory
concentration (MIC) and half-life data used to be the battleground. The predictive value
of the exposure of the pathogen to an antimicrobial and the time course of in vivo
concentrations to maximise efficacy in relation to possible side effects has also led to
evolving regulatory requirements. This is especially the case in the US where these
factors may now enable new antimicrobial agents to be developed more quickly and which
require fewer pivotal studies, resulting in clear cost implications. In Europe, Summaries
of Product Characteristics (SPCs) will only be able to include lists of susceptible
pathogens in approved indications and they must indicate the approximate proportion that
demonstrate resistance. The attitude of European agencies to 'fast tracking' is also
reviewed.
ES.7 The market structure
Chapter 7 describes the market structure in total and by each of the three main markets
(bacterial, fungal and viral), in terms of leading products, companies involved and the
importance of antimicrobials to company revenue. Six of the top 10 selling anti-infectives
are antibiotics, three are antifungals and only one is an antiviral - perhaps,
surprisingly, not an antiretroviral for HIV infection. Zovirax, for herpesvirus
infections, is ranked eighth. There are five antimicrobials with sales estimated to exceed
$1 billion in 1998. Two companies each have two products in the top 10, but none has two
antibiotics in the top 10. Two companies have more than 30% of total company
pharmaceutical sales in antibiotics. Only one company in the top 10 and four companies in
the top 20 (excluding the Japanese companies) do not have marketed antibiotics in their
portfolios.
Novartis is the only company in the top 15 without an antibiotic but it has the ninth ranked antimicrobial, which occupies second position in the antifungal rankings. Although the market is mature in terms of volume, opportunities do exist for innovation. Two of the top 10 ranking antibiotics and the top two ranking antifungals were introduced in the early 1990s. Usage of antimicrobials in hospitals in the US and Germany are compared, together with epidemiology - including data for pneumonia and otitis media.
With so many products in the pipeline, many of them later entries in existing classes, the
question of which will be winners is discussed. The prospects for the pipeline products -
sales potentials, rather than forecasts or predictions - and the existing market leaders
are reviewed in the context of patent expiry as well as competition from the new agents
and the pressure from the spread of resistance.
ES.8 Company profiles
The leading companies marketing anti-infective agents are profiled in Chapter 8, together
with selected smaller companies whose technology has produced some of the innovative
products that these major corporations have licensed. Appendix I contains contact details
