Exhibit 99.2
This presentation contains “forward-looking” statements that are within the meaning of federal securities laws
and are based on our management’s beliefs and assumptions and on information currently available to
management. Forward-looking statements include information concerning our possible or assumed future
results of operations, business strategies, financing plans, competitive position, industry environment, potential
growth opportunities, potential market opportunities and the effects of competition.
Forward-looking statements include all statements that are not historical facts and can be identified by terms
such as “anticipates,” “believes,” “could,” “seeks,” “estimates,” “intends,” “may,” “plans,” “potential,”
“predicts,” “projects,” “should,” “will,” “would” or similar expressions and the negatives of those terms. Forward-
looking statements represent our management’s beliefs and assumptions only as of the date of this
presentation. Our operations involve risks and uncertainties, many of which are outside our control, and any
one of which, or combination of which, could materially affect our results of operations and whether the
forward-looking statements ultimately prove to be correct. Factors that may materially affect our results of
operations include, among other things, those listed in our Annual Report on Form 10-K and other filings with the
Securities and Exchange Commission (“SEC”). Except as required by law, we assume no obligation to update
these forward-looking statements publicly, or to update the reasons actual results could differ materially from
those anticipated in the forward-looking statements, even if new information becomes available in the future.

Safe Harbor Statement
Successful Phase 2b Clinical Results – Advancing
Potential Blockbuster to Phase 3
• Statistically significant improvements in clinical disease versus
placebo across multiple endpoints 6 months post-dosing
• Compelling profile cemented across three clinical studies
– Durable impact on clinical disease
– Significant reduction in viral shedding
– At most once-yearly maintenance dosing
– Safety profile appropriate for therapeutic setting
• Important critical path milestones imminent
– End-of-phase 2 meeting with the FDA: Q1
– Phase 3 start: Q4
• If approved, would be the first new treatment for genital herpes
infections in more than 20 years
• Large unmet patient need in a disease of epidemic proportions
– Potential ~$2 billion global revenue opportunity*

Millions Infected with Genital Herpes Need a New
Treatment Option
•Most patients do not persist
– Loathe “daily reminder”
– Incomplete efficacy
• Little benefit
– No impact on
recurrence frequency
– Small reduction in
duration

GEN-003 Target Profile
• No pill burden
• Similar disease control
• Potential additive
effect as combo
• Reduce clinical
disease:
• Total lesion days
• Recurrence

• Reduce viral
shedding
• Minimize treatment

GEN-003 Phase 2b Trial
5
• Overall goal
– Evaluate Phase 3-ready formulation of GEN-003 and define dose for
Phase 3 trials
• Primary objective (completed successfully in September 2016(1))
– Compare efficacy of two dose levels of GEN-003 and placebo by
impact on viral shedding
• Secondary objectives
– Evaluate impact on clinical disease vs. placebo at 6 and 12 months
– Evaluate impact on viral shedding vs. placebo at 6 and 12 months
– Immunogenicity
– Safety and tolerability
6
Goals & Objectives
Note (1) Press release - http://ir.genocea.com/releasedetail.cfm?ReleaseID=991389
• Randomized, double-blind, placebo-controlled
• 131 subjects with a history of recurrent genital herpes
• 3 dose groups
– Placebo (n=44)
– 60 µg per antigen / 50 µg of Matrix-M adjuvant (n=43)
– 60 µg per antigen / 75 µg of Matrix-M adjuvant (n=44)
• Most other design elements consistent with prior GEN-003 trials
– Inclusion / exclusion criteria, demographics, sites, dose regimen,
viral shedding swabbing compliance
7
Study Design
• Phase 2b – more comprehensive
– Lesion data collected daily
throughout trial
– Data recorded via smartphone-
based app with reminders
• Previous GEN-003 studies
– Lesion data only during 28-day
observation periods
• Pre-treatment
• Immediately post-treatment
• 6 & 12 months post-treatment
– Data recorded via paper diary
based on recall
8
Improved Lesion Data Collection Strengthens
GEN-003 Clinical Endpoints Assessment
• Capture data on
additional clinical
endpoints:
– Number of recurrences
– Duration of recurrences
• Enables Phase 3-like
analysis across doses after
treatment, rather than
versus baseline

GEN-003 Drives Significant Improvement in Number of
Subjects Recurrence Free at 6 Months
Kaplan-Meier Estimate of % Subjects
Recurrence Free at 6 Months
• GEN-003 patients 2-3
