		6.2	Reporting. The Parties will promptly report to each other in writing each CRADA Subject Invention reported by their
respective personnel, and any Patent Applications filed thereon, resulting from the research and development activities conducted
under this CRADA. Each Party will report all CRADA Subject Inventions to the other Party in sufficient detail to determine inventorship,
which will be determined in accordance with U.S. patent law. These reports will be treated as Confidential Information in accordance
with Article 8. Formal reports will be made by and to the Patenting and Licensing Offices identified on the Contacts Information
Page herein.



 


		6.3	Filing of Patent Applications. Each Party will make timely decisions regarding the filing of Patent Applications on
the CRADA Subject Inventions made solely by its employee(s), and will notify the other Party in advance of filing. Collaborator
will have the first opportunity to file a Patent Application on joint CRADA Subject Inventions and will notify PHS of its decision
within sixty (60) days of an Invention being reported or at least thirty (30) days before any patent filing deadline, whichever
occurs sooner. If Collaborator fails to notify PHS of its decision within that time period or notifies PHS of its decision not
to file a Patent Application, then PHS has the right to file a Patent Application on the joint CRADA Subject Invention. Neither
Party will be obligated to file a Patent Application. Collaborator will place the following statement in any Patent Application
it files on a CRADA Subject Invention: “This invention was created in the performance of a Cooperative Research and Development
Agreement with the [INSERT into Agency’s model as appropriate: National Institutes of Health, Food and Drug Administration,
Centers for Disease Control and Prevention], an Agency of the Department of Health and Human Services. The Government of the
United States has certain rights in this invention.” If either Party files a Patent Application on a joint CRADA Subject
Invention, then the filing Party will include a statement within the Patent Application that clearly identifies the Parties and
states that the joint CRADA Subject Invention was made under this CRADA.



 


		6.4	Patent Expenses. Unless agreed otherwise, the Party filing a Patent Application will pay all preparation and filing
expenses, prosecution fees, issuance fees, post issuance fees, patent maintenance fees, annuities, interference expenses, and attorneys’
fees for that Patent Application and any resulting Patent(s). If a license to any CRADA Subject Invention is granted to Collaborator,
then Collaborator will be responsible for all expenses and fees, past and future, in connection with the preparation, filing, prosecution,
and maintenance of any Patent Applications and Patents claiming exclusively licensed CRADA Subject Inventions and will be responsible
for a pro-rated share, divided equally among all licensees, of those expenses and fees for non-exclusively licensed CRADA Subject
Inventions. Collaborator may waive its exclusive option rights at any time, and incur no subsequent financial obligation for those
Patent Application(s) or Patent(s).

		6.5	Prosecution of Patent Applications. The Party filing a Patent Application will provide the non-filing Party with a copy
of any official communication relating to prosecution of the Patent Application within thirty (30) days of transmission of the
communication. Each Party will also provide the other Party with the power to inspect and make copies of all documents retained
in the applicable Patent Application or Patent file. The Parties agree to consult with each other regarding the prosecution of
Patent Applications directed to joint CRADA Subject Inventions. If Collaborator elects to file and prosecute Patent Applications
on joint CRADA Subject Inventions, then Collaborator agrees to use the U.S.P.T.O. Customer Number Practice and/or grant PHS a power(s)
of attorney (or equivalent) necessary to assure PHS access to its intellectual property rights in these Patent Applications. PHS
and Collaborator will cooperate with each other to obtain necessary signatures on Patent Applications, assignments, or other documents.



 


		Article 7.	Licensing



 


		7.1	Background Inventions. Other than as specifically stated in this Article 7, nothing in this CRADA will be construed
to grant any rights in one Party’s Background Invention(s) to the other Party, except to the extent necessary for the Parties
to conduct the research and development activities described in the Research Plan.



 


		7.2	Collaborator’s License Option to CRADA Subject Inventions. With respect to Government rights to any CRADA Subject
Invention made solely by an ICD employee(s) or made jointly by an ICD employee(s) and a Collaborator employee(s) for which a Patent
Application was filed, PHS hereby grants to Collaborator an exclusive option to elect an exclusive or nonexclusive commercialization
license. The license will be substantially in the form of the appropriate model PHS license agreement and will fairly reflect the
nature of the CRADA Subject Invention, the relative contributions of the Parties to the CRADA Subject Invention and the CRADA,
a plan for the development and marketing of the CRADA Subject Invention, the risks incurred by Collaborator, and the costs of subsequent
research and development needed to bring the CRADA Subject Invention to the marketplace. The field of use of the license will not
exceed the scope of the Research Plan.



 


		7.3	Exercise of Collaborator’s License Option. To exercise the option of Paragraph 7.2 Collaborator must submit a
written notice to the PHS Patenting and Licensing Contact identified on the Contacts Information Page (and provide a copy to the
ICD Contact for CRADA Notices) within three (3) months after either (i) Collaborator receives written notice from PHS that the
Patent Application has been filed or (ii) the date on which Collaborator files the Patent Application. The written notice exercising
this option will include a completed “Application for License to Public Health Service Inventions” and will initiate
a negotiation period that expires nine (9) months after the exercise of the option. If PHS has not responded in writing to the
last proposal by Collaborator within this nine (9) month period, the negotiation period will be extended to expire one (1) month
after PHS so responds, during which month Collaborator may accept in writing the final license proposal of PHS. In the absence
of Collaborator’s exercise of the option, or upon election of a nonexclusive license, PHS will be free to license the CRADA
Subject Invention to others. These time periods may be extended at the sole discretion of PHS upon good cause shown in writing
by Collaborator.

		7.4	Government License in ICD Sole CRADA Subject Inventions and Joint CRADA Subject Inventions. Pursuant to 15 U.S.C. §
3710a(b)(l)(A), for CRADA Subject Inventions owned solely by ICD or jointly by ICD and Collaborator, and licensed pursuant to the
option of Paragraph 7.2, Collaborator grants to the Government a nonexclusive, nontransferable, irrevocable, paid-up license to
practice the CRADA Subject Invention or have the CRADA Subject Invention practiced throughout the world by or on behalf of the
Government. In the exercise of this license, the Government will not publicly disclose trade secrets or commercial or financial
information that is privileged or confidential within the meaning of 5 U.S.C. § 552(b)(4) or which would be considered privileged
or confidential if it had been obtained from a non-federal party.



 


		7.5	Government License in Collaborator Sole CRADA Subject Inventions.  Pursuant to 15 U.S.C. § 371 a(b)(2), for CRADA
Subject Inventions made solely by an employee of Collaborator, Collaborator grants to the Government a nonexclusive, nontransferable,
irrevocable, paid-up license to practice the CRADA Subject Invention or have the CRADA Subject Invention practiced throughout the
world by or on behalf of the Government for research or other Government purposes.



 


		7.6	Third Party License. Pursuant to 15 U.S.C. § 3710a(b)(l)(B), if PHS grants Collaborator an exclusive license to
a CRADA Subject Invention made solely by an ICD employee or jointly with a Collaborator employee, the Government will retain the
right to require Collaborator to grant to a responsible applicant a nonexclusive, partially exclusive, or exclusive sublicense
to use the CRADA Subject Invention in Collaborator’s licensed field of use on terms that are reasonable under the circumstances;
or, if Collaborator fails to grant a license, to grant a license itself. The exercise of these rights by the Government will only
be in exceptional circumstances and only if the Government determines (i) the action is necessary to meet health or safety needs
that are not reasonably satisfied by Collaborator, (ii) the action is necessary to meet requirements for public use specified by
federal regulations, and such requirements are not reasonably satisfied by Collaborator; or (iii) Collaborator has failed to comply
with an agreement containing provisions described in 15 U.S.C. § 3710a(c)(4)(B). The determination made by the Government
under this Paragraph is subject to administrative appeal and judicial review under 35 U.S.C. § 203(2).



 


		7.7	Third-Party Rights In ICD Sole CRADA Subject Inventions. For a CRADA Subject Invention conceived prior to the Effective
Date solely by an ICD employee that is first actually reduced to practice after the Effective Date in the performance of the Research
Plan, the option offered to Collaborator in Paragraph 7.2 may be restricted if, prior to the Effective Date, PHS had filed a Patent
Application and has either offered or granted a license in the CRADA Subject Invention to a third party. Collaborator nonetheless
retains the right to apply for a license to any such CRADA Subject Invention in accordance with the terms and procedures of 35
U.S.C. § 209 and 37 C.F.R. Part 404.

		7.8	Joint CRADA Subject Inventions Not Exclusively Licensed by Collaborator. If Collaborator does not acquire an exclusive
commercialization license in a joint CRADA Subject Invention in all fields of use then, for those fields of use not exclusively
licensed to Collaborator, each Party will have the right to use the joint CRADA Subject Invention and to license its use to others,
and each Party will cooperate with the other, as necessary, to fulfill international licensing requirements. The Parties may agree
to a joint licensing approach for any remaining fields of use.



 


		Article 8.	Rights of Access and Publication



 


		8.1	Right of Access to CRADA Data and CRADA Materials. ICD and Collaborator agree to exchange all CRADA Data and to share
all CRADA Materials. If the CRADA is terminated, both Parties agree to provide CRADA Materials in quantities needed to complete
the Research Plan. Such provision will occur before the termination date of the CRADA or sooner, if required by the Research Plan.
If Collaborator possesses any human biological specimens from clinical trials under the CRADA, the specimens must be handled as
described in the Protocol or as otherwise directed by ICD before the termination date of the CRADA.



 


		8.2	Use of CRADA Data and CRADA Materials. The Parties will be free to utilize CRADA Data and CRADA Materials internally
for their own purposes, consistent with their obligations under this CRADA. ICD may share CRADA Data or CRADA Materials with any
contractors, grantees, or agents it has engaged to conduct the CRADA research and development activities, provided the obligations
of this Article 8.2 are simultaneously conveyed. Collaborator may share CRADA Data or CRADA Materials with any contractors, Affiliates,
or agents it has engaged to conduct the CRADA research and development activities, provided the obligations of this Article 8.2
are simultaneously conveyed.



	



 




		8.2.1	CRADA Data.






Collaborator and ICD will use reasonable efforts to
keep CRADA Data confidential until published or until corresponding Patent Applications are filed. To the extent permitted by law,
each Party will have the right to use any and all CRADA Data in and for any regulatory filing by or on behalf of the Party.


 


		8.2.2	CRADA Materials.






Collaborator and ICD will use reasonable efforts to
keep descriptions of CRADA Materials confidential until published or until corresponding Patent Applications are filed. Collaborator
acknowledges that the basic research mission of PHS includes sharing with third parties for further research those research resources
made in whole or in part with NIH funding. Consistent with this mission and the tenets articulated in “Sharing of Biomedical
Research Resources: Principles and Guidelines for Recipients of NIH Research Grants and Contracts,” December 1999, available
at http://ott.od.nih.gov/NewPages/RTguide_final.html, following publication either Party may make available to third parties for
further research those CRADA Materials made jointly by both PHS and Collaborator. Notwithstanding the above, if those joint CRADA
Materials are the subject of a pending Patent Application or a Patent, or were created using a patent-pending or patented material
or technology, the Parties may agree to restrict distribution or freely distribute them. Either Party may distribute those CRADA
Materials made solely by the other Party only upon written consent from that other Party or that other Party’s designee.

		8.3	Confidential Information. Each Party agrees to limit its disclosure of Confidential Information to the amount necessary
to carry out the Research Plan, and will place a confidentiality notice on all this information. A Party orally disclosing Confidential
Information to the other Party will summarize the disclosure in writing and provide it to the other Party within fifteen (15) days
of the disclosure. Each Party receiving Confidential Information agrees to use it only for the purposes described in the Research
Plan. Either Party may object to the designation of information as Confidential Information by the other Party.



 


		8.4	Protection of Confidential Information. Confidential Information will not be disclosed, copied, reproduced or otherwise
made available to any other person or entity without the consent of the owning or providing Party except as required by a court
or administrative body of competent jurisdiction, or federal law or regulation. Each Party agrees to use reasonable efforts to
maintain the confidentiality of Confidential Information, which will in no instance be less effort than the Party uses to protect
its own Confidential Information. Each Party agrees that a Party receiving Confidential Information will not be liable for the
disclosure of that portion of the Confidential Information which, after notice to and consultation with the disclosing Party, the
receiving Party determines may not be lawfully withheld, provided the disclosing Party has been given a reasonable opportunity
to seek a court order to enjoin disclosure.



 


		8.5	Human Subject Protection. The research to be conducted under this CRADA involves Human Subjects or human tissues within
the meaning of 45 C.F.R. Part 46, and all research to be performed under this CRADA will conform to applicable federal laws and
regulations. Additional information is available from the HHS Office for Human Research Protections (http://www.hhs.gov/ohrp/).



 


		8.6	Duration of Confidentiality Obligation. The obligation to maintain the confidentiality of Confidential Information will
expire at the earlier of the date when the information is no longer Confidential Information as defined in Article 2 or three (3)
years after the expiration or termination date of this CRADA, except for IPI, for which the obligation to maintain confidentiality
will extend indefinitely. Collaborator may request an extension to this term when necessary to protect Confidential Information
relating to products not yet commercialized.

		8.7	Publication. The Parties are encouraged to make publicly available the results of their research and development activities.
Before either Party submits a paper or abstract for publication or otherwise intends to publicly disclose information about a CRADA
Subject Invention, CRADA Data, or CRADA Materials, the other Party will have thirty (30) days to review proposed manuscripts and
three (3) days to review proposed abstracts to assure that Confidential Information is protected. Either Party may request in writing
that the proposed publication or other disclosure be delayed for up to thirty (30) additional days as necessary to file a Patent
Application.



 


		8.8	Clinical Investigators’ Research and Development Activities. Although this CRADA does not grant to Collaborator
any rights to Inventions made or Raw Data generated by ICD’s contractors or grantees, as they are not parties to this CRADA,
ICD agrees that:



 


		8.8.1	Subject to the other provisions of Article 8 of this CRADA, ICD will maintain, to the extent permitted by law, all Clinical
Data in ICD’s Possession and Control as Confidential Information, and make them available to Collaborator for its own use
and for exclusive use in obtaining regulatory approval for the commercial marketing of Test Article and related CRADA Subject Inventions.



 


		8.8.2	With regard to Collaborator’s Confidential Information, ICD will require the Clinical Investigators to agree to confidentiality
provisions at least as restrictive as those provided in this CRADA and to Collaborator’s use of data in accordance with Paragraph
8.8.1 for obtaining regulatory approval for marketing Test Article.



 


		8.8.3	If Collaborator wants access to Raw Data or any other data in the possession of the Clinical Investigators working with Test
Article, Collaborator must first contact the CRADA PI. Collaborator will bear any costs associated with Raw Data provided in formats
customized for Collaborator.



 


		8.8.4	Collaborator’s right to access Clinical Data in ICD’s Possession and Control under Paragraph 8.8 is dependent upon
Collaborator’s continued development and commercialization of Investigational Agent. If Collaborator fails to continue development
or commercialization of Investigational Agent without the transfer of its development efforts to another party within ninety (90)
days of discontinuation, ICD has the right to make Clinical Data in ICD’s Possession and Control available to a third party.



 


		Article 9.	Representations and Warranties



 


		9.1	Representations of ICD. ICD hereby represents to Collaborator that:



 


		9.1.1	ICD has the requisite power and authority to enter into this CRADA and to perform according to its terms, and that ICD’s
official signing this CRADA has authority to do so.



 


		9.1.2	To the best of its knowledge and belief, neither ICD nor any of its personnel involved in this CRADA is presently subject to
debarment or suspension by any agency of the Government which would directly affect its performance of the CRADA. Should ICD or
any of its personnel involved in this CRADA be debarred or suspended during the term of this CRADA, ICD will notify Collaborator
within thirty (30) days of receipt of final notice.

		10.4	Funding for ICD Personnel. If Collaborator has agreed to provide funding for ICD personnel and this CRADA is mutually
or unilaterally terminated by Collaborator before its expiration, then Collaborator agrees that funds for that purpose will be
available to ICD for a period of six (6) months after the termination date or until the expiration date of the CRADA, whichever
occurs sooner. If there are insufficient funds to cover this expense, Collaborator agrees to pay the difference.



 


		10.5	New Commitments. Neither Party will incur new expenses related to this CRADA after expiration, mutual termination, or
a notice of a unilateral termination and will, to the extent feasible, cancel all outstanding commitments and contracts by the
termination date. Collaborator acknowledges that ICD will have the authority to retain and expend any funds for up to one (1) year
subsequent to the expiration or termination date to cover any unpaid costs obligated during the term of the CRADA in undertaking
the research and development activities set forth in the Research Plan.

NOT INFRINGE ANY THIRD-PARTY PATENT RIGHTS.



 


		12.2	Indemnification and Liability. Collaborator agrees to hold the Government harmless and to indemnify the Government for
all liabilities, demands, damages, expenses and losses arising out of the use by Collaborator for any purpose of the CRADA Data,
CRADA Materials or CRADA Subject Inventions produced in whole or part by ICD employees under this CRADA, unless due to the negligence
or willful misconduct of ICD, its employees, or agents. The Government has no statutory authority to indemnify Collaborator. Each
Party otherwise will be liable for any claims or damages it incurs in connection with this CRADA, except that ICD, as an agency
of the Government, assumes liability only to the extent provided under the Federal Tort Claims Act, 28 U.S.C. Chapter 171 .



 


		12.3	Force Majeure. Neither Party will be liable for any unforeseeable event beyond its reasonable control and not
caused by its own fault or negligence, which causes the Party to be unable to perform its obligations under this CRADA, and which
it has been unable to overcome by the exercise of due diligence. If a force majeure event occurs, the Party unable to perform
will promptly notify the other Party. It will use its best efforts to resume performance as quickly as possible and will suspend
performance only for such period of time as is necessary as a result of the force majeure event.

		1.	Goals of this CRADA



 


The principal research goal of this CRADA is to evaluate the
histological effects of treatment with the FXR (farnesoid X receptor) ligand INT-747 (6α-ethyl-chenodeoxycholic acid, obeticholic
acid) compared to treatment with placebo in patients with NASH to determine if ITN-747 improves nonalcoholic fatty liver disease
(NAFLD) as determined from hepatic histology.


 


		2.	Background



 


		2.1	Preclinical Rationale for Efficacy of the FXR Agonist
INT-747 in NASH



 


Non-alcoholic fatty liver disease (NAFLD) is considered the
hepatic manifestation of the metabolic syndrome, a cluster of closely related clinical features linked to visceral obesity and
characterized by insulin resistance, dyslipidemia and hypertension. Hepatocellular injury, inflammation and fibrosis are hallmarks
of non-alcoholic steatohepatitis (NASH), which develops in a fraction of subjects with NAFLD via mechanisms still not completely
understood. Several factors have been implicated in the development of NASH, including sensitization by excessive liver triglyceride
accumulation with insulin resistance and subsequent inflammatory and oxidative stress exposure (1). This study will evaluate if
INT-747 (obeticholic acid)- a semisynthetic bile acid and FXR agonist- will improve the histological features of NASH.


 


It has become increasingly recognized in recent years that bile
acids are potent physiological regulators of metabolism (2). Table I summarizes the many metabolic effects of bile acids, both
via Farnesoid X Receptor (FXR), a nuclear receptor, and TGR5, a G-protein coupled receptor expressed on the cell membrane (2).

FXR, a member of the nuclear receptor superfamily, is mainly
expressed in liver, intestine, kidney and adipose tissue where it regulates a wide variety of target genes critically involved
in the control of bile acid, lipid and glucose homeostasis (3). FXR agonists have been shown to suppress hepatic fatty acid and
triglyceride synthesis through down-regulation of SREBPlc (4), and increase hepatic fatty acid oxidation through up-regulation
of pyruvate dehydrogenase kinase (PDK4) (5). In addition, FXR agonists show insulin-sensitizing effects (3) and inhibit hepatic
inflammation (6). In mice fed a high-fat diet, treatment with recombinant human fibroblast growth factor 19 (FGF-19), a FXR target
gene markedly unregulated by FXR agonists, improves indices of dyslipidemia, hepatic steatosis, hyperinsulinemia, hyperleptinemia,
and insulin sensitivity, while reducing body weight and adiposity (7). A synthetic FXR agonist protects against NASH in mice fed
a methionine and choline-deficient diet (8). In this model, serum ALT and AST levels were reduced by treatment with the FXR agonist,
accompanied by significantly reduced inflammatory cell infiltration and hepatic fibrosis. The reduction in inflammatory cell infiltration
correlated with decreased serum levels of keratinocyte-derived chemokine and MCP 1, and the reduction of hepatic fibrosis corresponded
to a reduction in hepatic gene expression of fibrosis markers (8). FXR-deficient mice exhibit a hepatic phenotype similar to NASH
patients with significant hepatic triglyceride accumulation, hepatic inflammation and injury, and spontaneous hepatocellular carcinoma
development (9). Thus, several lines of evidence from preclinical studies support the concept that FXR agonists may prove clinically
useful for treating NASH (10).


 


INT-747 (6α-ethyl chenodeoxycholic acid, obeticholic acid)
is a semi-synthetic potent and selective FXR agonist based on a bile acid scaffold, originally described for its anti-cholestatic
and liver-protecting properties (11). INT-747 differs from chenodeoxycholic acid (COCA), the primary human bile acid and natural
FXR ligand in man, by the addition of an 6α-ethyl group (which confers 100x greater FXR agonist properties). More recent
preclinical studies have shown the capacity of INT-747 to increase insulin sensitivity, to modulate lipid metabolism and to exert
anti-inflammatory properties, together with a marked anti-fibrotic effect.

		2.1.1	INT-747 Reduces Hepatic Lipotoxicity and Insulin
Resistance



 


INT-747 induces lipid uptake by mouse adipocyte cell line (3T3-Ll)
(12) and primary human adipocytes (13), which correlate with reduced hepatic and circulating lipid levels, together with increased
insulin sensitivity. Moreover, INT-747 significantly enhances adiponectin and leptin (p<0.05 vs. differentiation mix) secretion
by mouse and human adipocytes (13), which can enhance insulin sensitivity in peripheral tissues. Pancreatic beta cells express
FXR mRNA and protein, and INT-747 significantly enhances insulin secretion by mouse β-TC6 cells (AUC P<0.05 vs. ctrl) and
human pancreatic islets (P<0.01 vs. ctrl). FXR knock down in β-TC6 cells abrogates the INT-747-induced glucose-dependent
insulin mRNA expression and secretion, indicating that these effects are FXR dependent (13). INT-747-induced insulin secretion
by β TC6 cells correlates with enhanced AKT phosphorylation and Glut-2 plasma membrane translocation (13), suggesting that
INT-747 might induce glucose uptake in these cells. INT-747 significantly up-regulates expression of PGC-1α in human hepatocytes
and in mouse beta cells (13), suggesting a potential mechanism of action for its capacity to increase insulin secretion. Collectively,
these results indicate that INT-747 improves glycemia by increasing peripheral glucose uptake, by enhancing glucose-stimulated
insulin secretion, and by inhibiting hepatic lipid synthesis and content while inducing lipid uptake by adipocytes.


 


		2.1.2	INT-747 Effects on Hepatic Inflammation, Fibrosis
& Portal Hypertension



 


In the db/db mouse model of NAFLD, oral treatment for 5 weeks
with INT-747 attenuates the NAFLD molecular profile, as demonstrated by reduced expression of inflammatory (TNF-α, TGF-β)
and fibrotic (TIMP, collagen, SMA) markers in liver tissue (14). In addition, increased monocyte-derived suppressor cells suggest
that FXR activation by INT-747 promote anti inflammatory monocyte infiltration into the liver (14). INT-747 selectively inhibits
the NF-κB mediated hepatic inflammatory response both in vitro and in vivo
while maintaining or even enhancing the cell survival response (6). In addition, INT-747 has been shown to inhibit vascular smooth
muscle cell inflammation by down-regulation of inducible nitric oxide synthase and cyclooxygenase-2 expression (15).

Hepatic fibrosis is a key histopathological feature in NASH
patients, and hepatic stellate cell (HSC) activation is critical for hepatic fibrosis. FXR is expressed in HSCs and regulates their
activation. INT-747 protects from liver fibrosis through inhibition of HSC activation in several rodent models (16). In the thioacetamide
model of liver fibrosis in rats, INT-747 prevents fibrosis progression, reverses fibrosis and cirrhosis development, and significantly
decreases portal hypertension (17). In addition, INT-747 reverses portal hypertension in a rat model of cirrhosis induced by bile
duct ligation (18).


 


		2.1.3	INT-747 and Erectile Dysfunction



 


Erectile dysfunction (ED) is often comorbid with obesity, diabetes,
and the metabolic syndrome (MetS) (19). MetS induces ED through several mechanisms, including endothelial dysfunction in penile
vessels. In a high-fat diet model of MetS in rabbits, a 3-month treatment with INT-747 restored endothelium-dependent relaxation
in isolated cavernous tissue, normalizing responsiveness to acetylcholine and to electrical field stimulation, suggesting that
NO production by NANC nerves is increased by INT-747 treatment (Maggi et al., manuscript in preparation). Accordingly, eNOS expression
in the penis is greatly up-regulated by INT-747 treatment. Preliminary experiments in a rat model of chemically induced type 1
diabetes further demonstrate that INT-747 treatment preserves erectile function induced by electrical stimulation of the cavernous
nerve. Evaluating both the prevalence of ED and the effects of INT-747 upon it in male patients with NASH is warranted.


 


Thus, the multiple activities of INT-747, including inhibition
of hepatic lipogenesis, increase in insulin sensitivity, hepatocyte protection against bile acid-induced cytotoxicity, anti inflammatory
effects in liver and vasculature, prevention and reversal of liver fibrosis, make this FXR agonist attractive for development as
a novel therapeutic agent in NASH.

		2.2	Clinical Overview of INT-747



 


INT-747, 6-ethyl chenodeoxycholic acid or obeticholic acid,
is a modified bile acid and potent FXR nuclear receptor agonist (and a weak agonist for TGR5, the cell membrane bile acid G protein
coupled receptor). Two Phase I and two Phase II studies have been completed. The key data are summarized below.


 


		2.2.1	Phase I Studies



 


The drug was administered to normal volunteers in single (25-500mg)
and multiple (25-250mg) dose studies. Findings are summarized here.


 


		·	Safety: No safety concerns arose with single dose administration. At 250mg, given for 12 days, 4 of 8 subjects reported pruritus
(generally mild); one of these dropped out of the study due to a rash. Elevations in ALT and AST (maximum value 5.2x ULN) occurred
in 6 of the 8 subjects (all resolved without sequelae). No clinically meaningful aminotransferase increases were seen at doses
of 100mg or lower.






		·	As expected, the drug was extensively conjugated (to glycine and taurine conjugates). There was considerable enterohepatic
circulation (lasting several days after the last dose was administered).



 


		2.2.2	Exploratory Study in Type 2 Diabetes and NAFLD-
Euglycemic Clamp



 


An exploratory study in patients with Type 2 diabetes and nonalcoholic
fatty liver disease (NAFLD) (diagnosed by hepatic ultrasound, elevated aminotransferases and/or liver biopsy) received placebo,
25mg or 50mg of INT-747 daily for 6 weeks. A 2-step hyperinsulinemic euglycemic clamp was conducted before and after treatment.


 


Key findings were:


 


		·	Improvements in the steady state glucose infusion rates at both the low and high-dose insulin clamp steps were seen with the
25 mg dose and when both doses were evaluated together, versus placebo (22). This is consistent with improvements in both hepatic
and peripheral (e.g. muscle, adipose tissue) glucose disposal.

		·	Weight loss was seen in a dose related manner; a fall in ~2% body weight occurred at 50mg after the six weeks of treatment
(p<0.01 versus placebo). FGF-19, a protein secreted from the gut directly under FXR control, with potent metabolic effects (20),
showed a similar dose related increase (which may in part explain the weight loss).



 


		·	ELF (Enhanced, formerly European, Liver Fibrosis) markers showed:



 


		·	~80% of patients had at least mild hepatic fibrosis



 


		·	statistically significant improvements in the composite ELF, and all the individual analyte, scores at the 25mg dose. There
were no meaningful changes at the 50mg dose.



 


		·	Other findings included:



 


		·	Liver enzymes: ~50% decrease in GGTP (both doses) and a significant fall in ALT at 25mg.



 


		·	Lipids: a decrease in triglycerides at the 50mg dose, and an increase in LDL; and decrease in HDL at 50mg. It should be noted
that each of the 4 centers used local laboratories and no lipid fractionation was conducted. Circulating lipids may not reflect
tissue lipid levels.



 


		·	There were no clear, concerning safety signals. Specifically, pruritus and aminotransferase increases were not seen more frequently
with INT-747 therapy. Constipation (generally mild) occurred in 24% of the patients at the 50mg group (which was surprising as
diarrhea was the most common AE seen with COCA therapy).



 


The data suggest that the dose response for insulin sensitivity
(which reached a maximum at 25mg) may differ from that for weight loss (where 50mg showed better results than 25mg). Longer, larger
studies are needed to evaluate if these apparent differences are real.


 


 This study showed that small doses of an oral FXR agonist
can induce meaningful improvements in glucose metabolism.

		2.2.3	Primary Biliary Cirrhosis (PBC) Studies



 


Two, very similar, Phase II studies in patients with PBC have
been initiated. Alkaline phosphatase (AP), assessed at central laboratories, is the primary endpoint in both studies. Therapy in
each lasts 3 months. A monotherapy study comparing the effects of 10mg and 50mg of INT-747 with placebo is ongoing. The double-blind
phase of the other, a dose response study evaluating 3 doses (10mg, 25mg and 50mg) with placebo in patients with persistent elevations
(>1.5x ULN) in AP levels on a stable dose of ursodeoxycholic acid (UDCA) has been completed. Thirty three (33) centers in 8
countries participated. This data was presented at the recent EASL meeting (21). The data showed:


 


		·	Highly statistically significant falls in AP levels in all doses compared with placebo (p<0.0001). Mean AP falls were ~20-25%
compared to 3% with placebo. Absolute AP falls ranged from ~ 65-75 IU/L versus 5 IU/L for placebo.



		·	Other evaluations of AP response (e.g. response rates) showed similar statistically and clinically meaningful differences from
placebo treatment.



		·	GGTP, ALT, AST and conjugated bilirubin levels were all significantly decreased with INT-747 treatment (mean pretreatment ALT,
AST and bilirubin levels were all within the normal range).



		·	Safety: Pruritus was the only clear clinically meaningful AE that differed between INT-747 treatment and placebo. The incidence
of pruritus was elevated at both the 25mg and 50mg doses in these cholestatic patients (but not at 10mg). However, the severity
of the pruritus and the incidence of discontinuations due to pruritus were both dose related. Overall, 10mg appeared to be acceptably
tolerated (and efficacious).



		·	Lipids: Effects were minimal with only a decrease in HDL seen. Future studies are planned to fractionate the HDL (and other)
components.



		·	Future studies will evaluate the effects of 10mg and lower doses given for longer periods in PBC.

In summary, INT-747 appears to be a potent agent whose effects
are consistent with the pre clinical findings of this FXR agonist. The PBC study has clearly shown that the drug has additional
efficacy to that seen with UDCA. The AE profile in the cholestatic PBC patients differed from that seen in the patients with diabetes
and NAFLD. Based on these preclinical and clinical data, a formal study evaluating the effects on histology in patients with NASH
is warranted.


 


		2.3	Background of the Parties



 


The National Institute of Diabetes and Digestive and Kidney
Diseases (NIDDK) is supporting the NASH Clinical Research Network (CRN) to conduct an extramural 12-year study of nonalcoholic
steatohepatitis (NASH) to help define the etiology, contributing factors, natural history, complications, and therapy of nonalcoholic
fatty liver disease in hopes of finding prevention and treatment approaches to this increasing cause of significant liver disease
in the United States. The NASH CRN consists of eight adult clinical centers and a data coordinating center.


 


Intercept Pharmaceuticals, Inc. is privately held biopharmaceutical
company developing novel therapeutics for the treatment of chronic fibrotic and metabolic diseases.


 


		3.	Detailed Description of the Research Plan:



 


		3.1	Type of Study



 


This CRADA will involve an extramural Phase II, multi-center,
double-masked, placebo controlled trial with parallel treatment groups with a 72-week histological change as the primary outcome.
The detailed description of the Research Plan is based on the protocol entitled “The Farnesoid X Receptor Ligand
Obeticholic Acid in Nash Treatment: FLINT Trial”. Dr. Patricia Robuck, The NIDDK Principal Investigator, will file the IND
for this trial with the FDA.

There will be a planned interim analysis by the trial Data and
Safety Monitoring Board (DSMB) after 15 months of enrollment, but before any end-of-trial liver biopsies are performed. The interim
analysis will be performed at 15 months with 24 week data from an estimated 25-40% of FLINT Trial patients. The interim analysis
will focus on (1) emergent safety issues, if any, and (2) difference in the mean changes of serum alanine aminotransferase (ALT)
by treatment group that are of sufficient magnitude and direction to warrant the continuation of enrollment and treatment of patients
toward the planned sample size and planned follow-up liver biopsies.


 


		3.2	Treatment Groups



 


This protocol will enroll approximately 280 patients 18 years
and older who will be randomly assigned to the following groups of equal size (approximately 140 patients in each group):


 


Group 1: Obeticholic acid (25 mg q.d.)


 


Group 2: Placebo


 


		3.3	Study Duration



 


The study duration is approximately four years (eighteen (18)
months for enrollment). There will be up to 16 weeks screening prior to randomization, including at least 3 months of drug dose
stabilization (or washout) for those using antiNASH medications prior to baseline liver biopsy or prior to randomization.. The
patients will undergo a 72-week treatment period followed by a 24- week post-treatment washout period.


 


		3.4	Recruitment



 


Recruitment of participants will take place at 8 NASH CRN clinical
centers within the U.S.


 





Target recruitment period: September 2010 - June 2012


 


Treatment and follow-up phase: September 2010 - December 2013

		3.9	Statistical Analysis



 


All primary analyses will be on an “intention-to-treat”
basis. The primary analysis is an intention-to-treat analysis in which the proportions of subjects in the active-treatment group
(obeticholic acid, 25 mg q.d.) with histological improvement in NAFLD, as defined by the primary outcome measure, is compared with
the proportion of subjects in the placebo group in whom there is improvement. The comparison is made with the use of the Mantel-Haenszel
chi square test, stratified according to clinical site. Subjects who do not undergo an end-of-treatment biopsy are classified as
not having had improvement.


 


		3.9.1	Sample Size Considerations



 


Total of 280 patients in 2 groups of equal size (140 per group)


 


Primary comparison: Obeticholic acid group vs. Placebo group


 


Primary outcome measure: Histological improvement in NAFLD (defined
above)


 


Error protection: Type I= 0.05 and Type II= 0.10 (90% power)


 


Missing data: 10% will not have 72 week biopsies and will be
considered not improved


 


Minimum clinically important difference: 50% higher relative
rate of improvement in the obeticholic acid group vs. the placebo group


Assumed response rates:


		1.	Expected percent with improved NAFLD (defined above) in the placebo group: 39% (based on PIVENS data and 2 to 1 split for patients
on vs. not on vitamin Eat start of trial)



		2.	Expected percent with improved NAFLD in the obeticholic acid group: 58%



 


		3.9.2	Interim Analysis



 


Will be performed at 15 months after 1st patient
randomized, at which time interim efficacy outcomes and safety information will be available on an estimated 25-40% of patients
with at least 24 weeks of follow-up data

AGREEMENT


FOR EXTRAMURAL-PHS CLINICAL RESEARCH


 


The interim target will be considered met if the observed between
treatment groups difference in serum ALT from baseline to 24 week favors the obeticholic acid treatment group and if the upper
95% confidence limit for the 24 week difference is compatible with (i.e., includes) a 20% net reduction, comparing the between
group difference relative to the mean at baseline of both groups combined.


Interim analysis for emergent safety issues will consists of
counts of adverse events (AEs) and serious adverse events (SAEs) by treatment group with associated P-values based on Fisher’s
exact test; the recommendation on safety will be made by DSMB, taking the P-values and all other relevant factors into account.


  


		3.10	Safety Monitoring



 


NIDDK appointed DSMB will monitor the data for safety and efficacy
for outcomes such as hepatotoxicity, pregnancy, and any other outcomes or events identified as safety-related. A member of the
NIDDK DSMB will serve as a liaison to Intercept’s Data Safety Monitoring Committee meetings and participate as necessary
to ensure safety surveillance across all of Intercept’s studies.





 


		4.	Respective Contributions of the Parties



 


		4.1	NIDDK will:



 


The NIDDK will be the central resource for the standardized
assessment of clinical parameters and will be utilized by all participating Clinical Centers. These central resources will function
and be supported under the Data Coordinating Center. The NIDDK and its Extramural Principal Investigator will perform the following
