Many of these groups are doing R&D on a shoestring how can we help?

Why am I here? Why are we here?

Page 3: Slides for rare disorders meeting

Jonah’s mum, Jill Wood started a foundation, raises money, awareness, funds ground breaking research happening globally. Willing to sell her house to fund research to save Jonah.

She is in a race against time – what can we do to translate ideas from bench to patient faster?

How do we get more ideas tested, who funds the research

How can we help parents and families ?

One example of why Pharmaceutical R&D needs disrupting

Page 4: Slides for rare disorders meeting

How to do it better?

What can we do with software to facilitate it ?

The future is more collaborative

We have tools but need integration

• Groups involved traverse the spectrum from pharma, academia, not for profit and government

• More free, open technologies to enable biomedical research• Precompetitive organizations, consortia..• How can it help orphan and rare diseases?

A starting point is collaboration; software may help

A core root of the current inefficiencies in drug discovery are due to organizations’ and individual’s barriers to collaborate effectivelyBunin & Ekins DDT

Example ; Collaborative Drug Discovery Platform

• CDD Vault – Secure web-based place for private data – private by default

• CDD Collaborate – Selectively share subsets of data

• CDD Public –public data sets - Over 3 Million compounds, with molecular properties, similarity and substructure searching, data plotting etc

will host datasets from companies, foundations etc

vendor libraries (Asinex, TimTec, ChemBridge)

• Unique to CDD – simultaneously query your private data, collaborators’ data, & public data, Easy GUI

3 Academia/ Govt lab – Industry screening partnerships

CDD used for data sharing / collaboration – along with cheminformatics expertise

Previously supported larger groups of labs – many continued as customers

How CDD software has been used: BMGF

CDD is a partner on a 5 year project supporting >20 labs and proving cheminformatics support www.mm4tb.org

Searching for TB molecular mimics; collaboration

Lamichhane G, et al Mbio, 2: e00301-10, 2011

Modeling – CDDBiology – Johns HopkinsChemistry – Texas A&M

Page 9: Slides for rare disorders meeting

Combining cheminformatics methods and pathway analysis Identified essential TB targets that had not been exploited Used resources available to both to identify targets and molecules that

mimic substrates Computationally searched >80,000 molecules - tested 23 compounds in

vitro (3 picked as inactives), lead to 2 proposed as mimics of D-fructose 1,6 bisphosphate, (MIC of 20 and 40 ug/ml)

POC took < 6mths - - Submitted phase II STTR, Submitted manuscript Still need to test vs target - verify hits vs suggested target

Ekins et al,Trends in Microbiology Feb 2011

Phase I STTR - NIAID funded collaboration with Stanford Research International

Sarker et al, submitted 2011

Finding Promiscuous Old Drugs for New Uses

Research published in the last six years - 34 studies - Screened libraries of FDA approved drugs against various whole cell or target assays.

1 or more compounds with a suggested new bioactivity

13 drugs were active against more than one additional disease in vitro Perhaps screen these first?

Ekins and Williams, Pharm Res 28(8):1785-91, 2011

Page 11: Slides for rare disorders meeting

Finding Promiscuous Old Drugs for New Uses

109 molecules were identified by screening in vitro

Statistically more hydrophobic (log P) and higher MWT than orphan-designated products with at least one marketing approval for a common disease indication or one marketing approval for a rare disease from the FDA’s rare disease research database.

Created multiple structure searchable databases in CDD This work was unfunded

Data in publications is increasing but who is tracking it?

FDA databases for rare disease research are XL files!!

After this paper published NCGC released NPC browser….but

Page 12: Slides for rare disorders meeting

Government Databases Should Come With a Health Warning

Openness Can Bring Serious Quality Issues

NPC Browser http://tripod.nih.gov/npc/Database released and within days 100’s of errors found in structures

2D Similarity search with “hit” from screening

Export database and use for 3D searching with a pharmacophore or other model

Suggest approved

drugs for testing - may also

indicate other uses if it is

present in more than one database

Suggest in silico hits for in vitro screening

Key databases of structures and bioactivity data FDA drugs

database

Repurpose FDA drugs in silico

Crowdsourcing Project “Off the Shelf R&D”

All pharmas have assets on shelf that reached clinic

“Off the Shelf R&D”

Get the crowd to help in repurposing / repositioning these assets

How can software help?

- Create communities to test

- Provide informatics tools that are accessible to the crowd - enlarge user base

- Data storage on cloud – integration with public data

- Crowd becomes virtual pharma-CROs and the “customer” for enabling services

Massive models – using open tools

Gupta RR, et al., Drug Metab Dispos, 38: 2083-2090, 2010

CDK +fragment descriptors MOE 2D +fragment descriptorsKappa 0.65 0.67

sensitivity 0.86 0.86specificity 0.78 0.8

PPV 0.84 0.84

Can we get pharmas to share models rather than data – precompetitive?

What can be developed with very large training and test sets?training 194,000 and testing 39,000

Open molecular descriptors / models vs commercial descriptors

Potential to share models selectively with collaborators e.g. academics, rare & neglected disease researchers

Page 16: Slides for rare disorders meeting

Future Drug Discovery

Could our Pharma R&D look like this – a big network

I think we are seeing something like this with all the orphan disease networks

Massive collaboration networks – software enabled. We are in “Generation App”

Crowdsourcing will have a role in R&D. Drug discovery possible by anyone with “app access”

Ekins & Williams, Pharm Res, 27: 393-395, 2010.

Page 17: Slides for rare disorders meeting

•Make science more accessible = >communication

•Mobile – take a phone into field /lab and do science more readily than on a laptop

•MolSync + DropBox + MMDS = Share molecules as SDF files on the cloud = collaborate

•How could orphan disease research leverage apps?

Mobile Apps for Drug Discovery

Need to learn from neglected disease research

Do we really need to screen massive libraries of compounds as we have for TB and malaria?

Page 19: Slides for rare disorders meeting

Evolving paradigm for the discovery of medicines (Collaborative) A vision that points towards open innovation and collaborations Open research model to collectively share scientific expertise

Enhance speed of drug discovery beyond individual resource capabilities (Speed) Limited research budgets and capabilities driving greater shared resources Goal to see all partners succeed by accelerating the SCIENCE Synergize Pfizer’s strengths with Research Partners (Knowledge) Pair Pfizer’s design, cutting edge tools, synthetic excellence with research partners (academics, not-for-profits,

venture capitalists, or biotechs) to develop break through science, novel targets, and indications of unmet medical need

Current example of academic and not-for-profits partners (Discover and Publish) Drive to publish in top journal with science receiving high visibility and interest

Body clock mouse study suggests new drug potentialMon, Aug 23 2010By Kate KellandLONDON (Reuters) - Scientists have used experimental drugs being developed by Pfizer to reset and restart the body clock of mice in a lab and say their work may offer clues on a range of human disorders, from jetlag to bipolar disorder.

a few months ago we entered into a collaboration with the giant pharmaceutical industry Pfizer to test some of their leading molecules for potential relevance to HD.

The newest reality

Gone full circle

Pharma now becoming more like rare disease groups

Working on a shoestring, limited resources, leverages academics, partners with disease foundations, funded by them – open innovation

Collaboration is a core element

If Jill Wood can become a virtual pharma, Pfizer and other pharmas can be more like Jill and other parent entrepreneurs, smaller, leaner, working on many more diseases as collaborators

Page 21: Slides for rare disorders meeting

1. Write grants to fund researchers to develop products.

2. Write papers about rare disease to draw attention to urgency.

3. Organize special Journal issues on rare disease research.

4. Leverage my collaborative network to do preclinical research.

5. Use virtual screening to narrow down FDA and GRAS molecules to be repurposed.

6. Use computational models to predict potential toxicities for compounds for rare diseases.

7. Lobby funding agencies to support rare disease research.

8. Leverage as much open software, data and free resources as possible.

9. Maximally collaborative, results driven, no IP, socially networked.

10. Create a template for more disruptive research.

2012 my goals – Open research, focused on rare diseases, Fundable?
