2. FORWARD-LOOKING STATEMENTS
This presentation contains “forward-looking statements” within the meaning of the federal securities laws, which statements are subject to substantial risks and
uncertainties and are based on estimates and assumptions. All statements, other than statements of historical facts included in this presentation, including statements
concerning our plans, objectives, goals, strategies, future events, future revenues or performance, plans or intentions relating to product candidates, estimates of market
size, estimates of market growth, business trends, the anticipated timing, design and conduct of our planned clinical trials, the development of our product candidates,
including the timing and likelihood of regulatory filings and approvals for our product candidates, our ability to commercialize our product candidates, if approved, the
pricing and reimbursement of our product candidates, if approved, the potential to develop future product candidates, the potential benefits of strategic collaborations
and our intent to enter into any strategic arrangements, the timing and likelihood of success, plans and objectives of management for future operations and future results
of anticipated product development efforts, are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “might,”
“will,” “objective,” “intend,” “should,” “could,” “can,” “would,” “expect,” “believe,” “design,” “estimate,” “predict,” “potential,” “plan” or the negative of these terms,
and similar expressions intended to identify forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that could
cause our actual results to differ materially from the forward-looking statements expressed or implied in this presentation, including those described in “Risk Factors” and
“Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31,
2020, and elsewhere in such filing and in other subsequent disclosure documents, including our Quarterly Reports on Form 10-Q, filed with the U.S. Securities and
Exchange Commission (SEC).
We cannot assure you that we will realize the results, benefits or developments that we expect or anticipate or, even if substantially realized, that they will result in the
consequences or affect us or our business in the way expected. Forward-looking statements are not historical facts and reflect our current views with respect to future
events. Given the significant uncertainties, you should evaluate all forward-looking statements made in this presentation in the context of these risks and uncertainties and
not place undue reliance on these forward-looking statements as predictions of future events. All forward-looking statements in this presentation apply only as of the date
made and are expressly qualified in their entirety by the cautionary statements included in this presentation. We disclaim any intent to publicly update or revise any
forward-looking statements to reflect subsequent events or circumstances, except as required by law.
Industry and Market Data: We obtained the industry, market, and competitive position data used throughout this presentation from our own internal estimates and
research, as well as from industry and general publications, and research, surveys, and studies conducted by third parties. Internal estimates are derived from publicly
available information released by industry analysts and third-party sources, our internal research and our industry experience, and are based on assumptions made by us
based on such data and our knowledge of the industry and market, which we believe to be reasonable. In addition, while we believe the industry, market, and competitive
position data included in this prospectus is reliable and based on reasonable assumptions, we have not independently verified any third-party information, and all such
data involve risks and uncertainties and are subject to change based on various factors. These and other factors could cause results to differ materially from those
expressed in the estimates made by the independent parties and by us.
4. THERAPEUTICS PROGRAMS
For drugs that today must be injected,
our ingestible capsule technology could
enable needle-free, oral delivery and
systemic uptake of large molecules.
For people who suffer from gastrointestinal
diseases, delivering therapeutics directly
to the site of disease could enable safer
and more effective drug therapies.

Needle-free, oral delivery to small intestine designed for optimal systemic uptake
Large molecules/proteins are
poorly absorbed in the intestine;
currently delivered by injection only
► Injections are painful
and inconvenient
► Oral delivery is an attractive
alternative
► Oral delivery can differentiate
molecules approved as biosimilars
that would otherwise be injected
► Promising initial preclinical data with
average bioavailability of ~15% of IV
for PGN-OB1 following a single dose1
► Initiated preclinical study of PGN-OB1
(variant of adalumimab)
► Initiated preclinical study of PGN-OB2
(GLP-1 agonist)
Needle-free liquid jet injection in
the small intestine designed for
optimal systemic uptake of:
► monoclonal antibodies
► peptides
► nucleic acids

Targeted delivery of therapeutics to the site of disease intended to improve efficacy and safety
Some diseases involving the GI
tract, such as inflammatory bowel
diseases (IBD), have extremely poor
outcomes with existing therapies
► Efficacy is often limited by
inability to achieve therapeutic
drug levels due to safety
concerns at higher doses
► Established IBD Clinical Advisory Board
► Completed preclinical study
demonstrating high colon tissue
concentrations and low systemic
concentrations for PGN-600 (tofacitinib)
► Completed clinical study demonstrating
device safety and function
► Designing first clinical study for PGN-
600 (variant of adalimumab)
► Continued funding from the Crohn’s &
Colitis Foundation
Replace systemic drug therapy with
targeted, direct-to-site drug therapies
designed to improve efficacy and
safety
► Higher drug levels in the tissue
where it is needed
► Lower drug levels in systemic
circulation to reduce unwanted side
effects

► DIAGNOSIS OF PREECLAMPSIA RELIES ON METHODS INVENTED IN THE 1800s
Current assessment tools are sub-optimal
► THERE IS NO SINGLE TEST FOR PREECLAMPSIA
Current tests, like blood pressure, are not specific to
preeclampsia and cannot differentiate preeclampsia
from other hypertensive disorders, such as chronic or
gestational hypertension

the first blood test to assess risk by evaluating
multiple pathophysiological pathways.
