Antibiotics

• Not active against some bacteria – Natural resistance

• Different antibiotics required for different agents • Relapsing infection • Trigger to treat required • Compliance/Side effects

– 44% completed 60 day course during BA letter attacks BUT • Broad spectrum of activity • No predefined threat spectrum

UNCLASSIFIED

CFI is a broad spectrum antibiotic effective against multiple BW agents

• Treatment with encapsulated

ciprofloxacin effectively treats three BW agents: F. tularensis, Y. pestis and C. burnetii

• In collaboration with Health Protection Agency, Defence Research and Development Canada and Aradigm Corporation

UNCLASSIFIED

Humanised Antibody for the Treatment of Venezuelan Equine Encephalitis Virus (VEEV)

• No available licensed vaccines or antivirals for treatment of VEEV

• A mouse monoclonal antibody is effective for the treatment of VEEV in a mouse model of disease

• Humanised antibody produced to reduce potential adverse reactions in humans

– biologically active

– protects mice against lethal VEEV challenge

Summary

• A flexible response is essential

• Vaccines provide excellent protection for those immunised before exposure

• Post-exposure therapies provide a rapid response capability against some agents

• Following a BW attack, and for some agents, it will be necessary to use both post-exposure therapies and vaccines

Background: biothreat agents

• Pathogenic for man or animals

• Very low infectious dose

• Infectious via the inhalational route

• Cause endemic disease around world

• Usually are zoonotic diseases

• Lethal or incapacitating


31 March 2014


31 March 2014

Defence against biothreats

• Many potential biothreat agents • How to defend against them? • Impossible to make a vaccine/therapy for every potential agent • Require generic therapy

Generic approach to therapy • By influencing the host response

• Requires an understanding of the host response to pathogen & safe ways to influence it

• Requires identification of relevant targets or pathways in the host

31 March 2014


Innate (host) response targets for therapy

• Objective of this competition is to look broadly across research and development to identify host cell targets and pathways

• Using data derived from diverse infection models

• Respondents to competition do not need to work directly with biothreat agents

• Ultimate aim is to apply the most innovative approaches to biothreat agents

31 March 2014


CDE themed competition specifics • Seeking innovative proposals for short projects (<1year); £30-

80k guide; (£500k total budget)

• Show proof-of-concept for your proposal; there is funding allocated for follow-on work for successful projects

• Competition divided into 3 challenges

• Respondents need to address 1 of the challenges, may address >1, do not have to address all 3

• Challenges described fully in the competition document

• Bids must be ethical and compliant with UK government legislation

31 March 2014


Challenge 1


31 March 2014

Identification of new cellular or host pathway targets

Identification of new cellular or host pathway targets • In host-pathogen model of your choice

– Does not need to be a biodefence pathogen – Does not need to be in vivo

• Conditioning of cells ex vivo eg to profile responses or prior to adoptive transfer

• Targeting cells in situ eg – to refocus them – to activate them – to induce them to traffic – to redirect them


31 March 2014

Identification of new cellular or host pathway targets May involve the identification of eg • immuno stimulants • modulators • transfection factors • chemokines, cytokines or the induction (or blockade) of these • cytokine/chemokine/growth factor receptors and application of these to modulate host responses


31 March 2014

Identification of new cellular or host pathway targets

• Some of these may be

exogenous and some endogenous factors

• Some endogenous natural

regulators /regulatory pathways may be exploited

• to reduce inflammation and to restore homeostasis


31 March 2014

Normal

Overactive Underactive

Possible outcomes Proposals for

– identification of new cellular targets /pathways – new applications of manipulating known cellular targets/pathways – demonstration that targets may be influenced beneficially, for

example to: • prevent cytotoxicity • prevent/reduce microbial invasion • reduce microbial load • restore normal cell function


31 March 2014

Challenge 2

Identification of new candidate therapies


31 March 2014

Identification of new candidate therapies Exploit appropriate cellular targets and pathways to identify new therapies by, for example:

• enhancing cell-mediated immunity • investigating novel combinations • identification and manipulation of significant

transcription factors • micro RNA-directed therapies or antagonists


31 March 2014

Possible outcomes • Candidate therapies should be druggable and generic • Proposals should show proof-of-concept

• Does not exclude the re-purposing or augmentation of existing

therapies


31 March 2014

Challenge 3

Identification of new platform technologies


31 March 2014

Identification of new platform technologies

For assessing therapeutic benefit • Novel technologies such as:

• non-invasive methods of in-vivo/ex-vivo analysis eg bio-imaging or tracking

• Transcriptomics including micro RNA analysis

• In-silico modelling of host responses

• Novel assays to monitor the host immune response


31 March 2014

Possible outcomes

• New technologies which may facilitate the identification and development of candidate therapies

• Proposals should demonstrate the impact of the technology on therapeutic development


31 March 2014

What we want • Highly innovative approaches that are significantly different from

existing technologies

• Generally technology readiness level (TRL) ≤ 3

• Generic approaches (not pathogen specific)

• Approaches applicable to intracellular pathogens where

appropriate

• Approaches that will lead to a feasible clinical product


31 March 2014

What we don’t want Proposals that concern: • high technology readiness level (TRL) capability • serological targets only (rather than cellular) • antibody-based therapies (but antibodies as a targeting

mechanism are acceptable) • existing solutions or technology already tested and found to

have limited utility • a paper study or review or similar • pre-exposure therapies or therapeutics • topical therapies for wounds


31 March 2014

Successful proposals

• Each will be assigned a Technical Partner

– Provides interface between project and defence community

– If project successful, potential routes to exploitation developed


31 March 2014

Summary

• Competition launches today • Webinar Tuesday 1 April • Closes on Thursday 5 June 2014 at 17:00 hrs • Short proof-of-concept proposals • If successful, potential for follow-on funding • May include additional research to develop technology for MOD • Competition information available on CDE website
