New Opportunities
▪ We are collaborating with a medical consortium in Singapore interested in
exploring the development of RGN-352 to treat myocardial infarction. They are
submitting a major grant to study RGN-352 in large animals to evaluate safety,
efficacy, and determine a dose response for MI. Data gained from this study
should be directly applicable to humans and allow us, or a partner, to more
readily move into Phase 2 human trials in Asia and/or U.S.
▪ A group of physicians and researchers at major U.S. medical institutions are
evaluating the relationship between Tβ4 and F-actin in patients with septic
shock. As recently reported in “Expert Opinion,” there appears to be a
correlation between patients that develop severe septic shock, with a historical
40% mortality rate, with high levels of F-actin and low levels of Tβ4. Since time
is of the essence in septic shock cases, should this correlation prove to be an
accurate prognostic we believe it would offer an opportunity utilize RGN-352 for
treatment of this critical subgroup of sepsis patients. Work is currently ongoing
in establishing this correlation and results should be available this year.

Common Stockholder Questions
1. Explain the ARISE-3 Trial Protocol and will it use CAE?
• The ARISE-3 trial protocol is designed to build on the results of ARISE-2. That is to say
that it will utilize the efficacy results seen in ARISE-2 as primary endpoints in ARISE-3 in the
same CAE model. FDA has approved the trial protocol.
• Primary endpoint 1 = Day 15 symptom evaluation compared to baseline
• Primary endpoint 2 = Day 15 sign evaluation in patients in lower 50 percentile (more
severe patients) compared to baseline
16OTCQB: RGRX
Common Stockholder Questions
2. What is the status of the NK trial, why were some data released to the public, and what are
the future plans for the study?
• The NK trial was designed to enroll 46 patients and is ongoing. However, as with many
orphan diseases, recruiting patients has been very slow. Our partners at Gtree observed
that 7 out of 17 patients had completely healed, which is the endpoint of the treatment,
although it is not known what group(s) the patients were in since the study has not been
unmasked. The ReGenTree team will have to decide whether to try to complete the trial
with 46 patients or unmask it after 17 to see where the responses were. That decision
has not been made as yet.
17OTCQB: RGRX
Common Stockholder Questions
3. Why does clinical trial information seem slow in reaching stockholders?
• Our partner, GtreeBNT, controls the outflow of information emanating from the dry eye
and NK clinical trials. They are very thorough in evaluating data and do not release it
prematurely. Gtree and RegeneRx try to coordinated the simultaneous release of
material information. Occasionally, we see information released in Korea that has not
been released in the U.S. In those cases, we have to confirm the information, and when
confirmed, we release it in the U.S. This can take awhile. Coordination between
companies and countries with sometimes different agendas, regulations, and control of
information can be complicated. Moreover, legal liability requires us to be as certain as
possible of information before we disseminate it.
18OTCQB: RGRX
Common Stockholder Questions
5. Why does it take so long to upload information on clinicaltrials.gov?
• ReGenTree is operated by GtreeBNT and is the sponsor of the dry eye and NK trials. It
is, therefore, responsible for uploading clinical trial information. ReGenTree is aware of
its obligations and time lines related to reporting information to clinicaltrials.gov.
19OTCQB: RGRX
Common Stockholder Questions
6. Explain the terms of the ReGenTree joint venture. Who operates and controls the JV?
• The ReGenTree JV is a U.S. joint venture owned by RegeneRx and GtreeBNT. Its terms
are flexible depending on sales milestones and future commercialization efforts.
• The JV started out 51% owned by GtreeBNT and 49% by RegeneRx
• The equity percentage has changed based on clinical milestones obtained by the JV. The current equity
percentage by RGRX is 38.5%. The minimum equity percentage by RGRX would be 25% if the JV obtains
an NDA.
• Separate from the equity ownership, RGRX retains a royalty on future commercial sales between mid-
single digits and low double digits, depending on the type or continuing combination of commercialization
efforts.
• In the event the JV is sold to a third party such as a multi-national pharmaceutical company, which would
unlikely accept a continued royalty obligation, RGRX would receive no less than 40% of the value of the
sale.
• GtreeBNT is required under the JV to fund 100% of the clinical development through NDA approval. It is
estimated Gtree has spent over $50 million to date to sponsor the clinical trials and conduct all the non-
clinical and CMC work necessary for production and a future NDA. RGRX has no funding responsibility at
any time.
• By contract, RGRX has 1 of 3 board seats on the JV. Importantly, unanimous board approval is required
for any major financial or strategic transaction, essentially giving RGRX veto power over all major
transactions and giving RGRX a significant amount of control on the future of the JV.
• RegeneRx retains all rights to RGN-259 in the EU.
20OTCQB: RGRX
Common Stockholder Questions
7. Can RGRX partners/licensees separately patent inventions related to the Licensed Product to
the detriment of RGRX? Why is patent status sometimes available online before being
released by RGRX? Is there only a single patent for a specific medical use or do patents
overlap in coverage.
• RGRX partners or licensees may separately patent inventions related to our Licensed Products.
However, if they do so RegeneRx will receive an exclusive, royalty-free license to practice such
inventions in all non-licensed territories, and even within the licensed territory for a non-licensed field.
Therefore, any such inventions could potentially be of significant benefit to RGRX.
• Patent application status is often published online without any head’s up to the inventors, the assignee, or
the legal firm, as, too, are sometimes FDA actions. RGRX finds out at the same time the public may find
out. However, unlike the public, we do not comment on such things until we receive official notifications
as we have to be certain and accurate with our public disclosures. Also, sometimes there are
uncertainties associated with the online publications and we cannot comment because we do not know
the final answer. The public, of course, can comment anytime without any obligation for accuracy.
• Most people do not fully understand patents. Patents typically serve two purposes: (1) to offer exclusivity
to the inventor(s) for a certain period of time and/or (2) to enable the practice of the invention. We strive
to maximize both of these strategies. Patents often overlap, with one being broad and another being
specific, or one covering a medical indication and another covering a composition or manufacturing
process. The expiries often cover different time periods so that when one expires on a certain aspect of
an invention another is still in effect continuing the exclusivity of an invention. Therefore, a patent
portfolio may have many patents with many claims that complement and overlap each other and
designed to create as much protection as possible over as long a period as possible.
