Coley’s founding technology:
CpG oligonucleotides TLR9 agonists
 Initial discovery was finding the molecular pattern in
bacteria and DNA viruses that turns on the immune
system shortly after infection
 Specific DNA sequence known as “CpG motifs”
 Activate through Toll-like receptor 9 found on certain
immune cells
 Coley discovered and developed synthetic CpG drugs
 Platform technology with wide potential applications
 Adjuvants for vaccines
• Made current vaccines work better – can use lower
doses (antigen sparing important during pandemic)
• Allowed development of new types of therapeutic
vaccines
 Cancer immunotherapy
 Treatment for asthma and allergy

How to succeed in biotech
 Founder characteristics
 Secure financing
 Recruit senior management
 Valuable technology, protected by IP
 Luck & timing
6
Founder characteristics
 Hard working, driven
 Adaptable
 Able to wear many hats
 Successful transition from academia to corporate world
requires thinking differently
 Hard working
7
Securing financing
 Coley had 1 year funding from founder
 Initial venture funding was Swiss / German
investors who had previously invested in corporate
founder
 Subsequent rounds introduced US investors
 No Canadian VC’s ever participated
 Too late
 Expected too much control for their investment
8
Recruit senior management
 Founders rarely make good senior managers
 Coley benefitted for 3 years by using senior management of
another company
 Coley later hired own management team
 Huge advantage having head office in Boston area
• Candidates with senior drug development experience are relatively rare in Canad
 Critical hires since each represents a single point of failure
 Drug development complex and only learned through experience
• Senior executives coming from Big Pharma sometimes couldn’t scale
down to biotech appropriate activities

Valuable technology
 Technology must actually work
 Positive clinical data trumps all
 Selling technology on mouse data possible, but typically brings low
value or back-loaded deals
 Platform technologies have greater chance to succeed
 Need to know when to let go
 Unrealistic for biotech company to expect to develop pharmaceutical
product to market
 IP protection critical
 Needs to be broad in scope and geography
 IP protection costs escalate rapidly after provisional filing – difficult for
academic unit to sustain until alternate financing secured
