Inventiva Announces Last Visit by Last Patient in its Phase IIb SSc Trial and Second Positive DSMB Review in its Phase IIb NASH Trial with Lanifibranor

October 15, 2018

> Top-line results of the Phase IIb systemic sclerosis (SSc) trial are expected for early 2019

> Second NASH DSMB recommends to continue the trial with lanifibranor without changing the protocol

Daix (France), October 15, 2018 – Inventiva S.A. (“Inventiva” or the “Company”), a biopharmaceutical company developing innovative therapies in nonalcoholic steatohepatitis (NASH), systemic sclerosis (SSc) and mucopolysaccharidosis (MPS), today announced the last visit by the last patient in its Phase IIb FASST (For A Systemic Sclerosis Treatment) trial as well as the second positive review of the Data Safety Monitoring Board (DSMB) in its Phase IIb NATIVE (NASH Trial to Validate IVA337 Efficacy) trial, both conducted with lanifibranor.

The last visit of the last patient of the 12-month FAAST study took place on October 12 and data-base lock is planned for early January 2019. With this positive background, the Company confirmed that it expects to announce top-line results of the study in early 2019 as previously announced.

“SSc is a debilitating disease with no disease-modifying treatments approved so far where lanifibranor mechanism of action could prove beneficial for our patients. Given that all three DSMB meetings regarding the FASST trial recommended to pursue with the study without any modifications to the protocol, we are very eager to see the results of this study,” said Yannick Allanore, co-principal investigator of the FASST trial and professor of rheumatology at the Hôpital Cochin in Paris.

Professor Christopher Denton, co-principal investigator of the FASST trial and professor at the University College London, added: “The FASST trial is a long-term study in SSc patients that will evaluate clinical endpoints highly relevant to clinicians, patients and health authorities. Positive results in this study would therefore be very supportive to the development of lanifibranor as a treatment in this very severe disease.”

Additionally, the DSMB from the Company’s NATIVE trial in NASH patients held its second meeting. Out of the 101 patients randomized so far, the DSMB had access to the data of 95 patients of which 36 had completed the 6 month treatment period of the study. Based on its analysis, the DSMB recommended the study to continue without any modification of the protocol.

Pierre Broqua, CSO and cofounder of Inventiva, stated: “We are very satisfied with the progress of the FASST study and excited by the prospect of publishing the head-line results early next year. The results of the second DSMB meeting regarding our NATIVE study are also very encouraging and headline results are expected for the first half of 2020.”

About the Phase IIb FASST trial

The Phase IIb FASST trial is a one-year randomized double-blind study designed to measure the effect of lanifibranor on the progression of SSc. Patients receive either lanifibranor or placebo according to the study protocol, approved by the European Medicines Agency (EMA). The primary endpoint is change in the Modified Rodnan Skin Score (MRSS), which is a measure of disease progression accepted by both the Food and Drug 1

Administration (FDA) and EMA. Inclusion criteria are based on a MRSS between 10 and 25 points, and diffuse SSc diagnosed from less than 3 years. Patients are allowed to continue their ongoing treatments, including immunosuppressive therapies. Lanifibranor has been granted Orphan Drug status for the treatment of SSc by the EMA and the FDA (respectively in November 2014 and March 2015). Orphan Drug status provides certain advantages for the sponsor, such as reduced procedure costs and commercial exclusivity.

About the Phase IIb NATIVE trial

The Phase IIb NATIVE trial is a 24-week randomized double-blind study designed to assess the efficacy of lanifibranor on ballooning and inflammation without worsening of fibrosis. Patients receive either lanifibranor or placebo. This trial also evaluates the safety of lanifibranor treatment. The main inclusion and assessment criteria of the study are based on the hepatic histology of each patient: (i) NASH histological diagnosis according to the NASH Clinical Research Network criteria (steatosis, lobular inflammation of any degree and liver cell ballooning of any amount) and (ii) SAF activity score of 3 or 4 (> 2), SAF Steatosis score >= 1 and SAF Fibrosis score < 4. The primary endpoint of the study is a decrease in relation to the baseline of >= 2 points of the SAF activity score combining hepatocellular inflammation and ballooning.

About lanifibranor

Lanifibranor is a next generation panPPAR modulator, designed as a moderately potent and well-balanced PPAR α, γ and δ. This unique profile was conceived in order to obtain an optimal therapeutic margin with strong efficacy and tolerance. Lanifibranor is currently being evaluated in two parallel Phase IIb clinical studies in NASH and SSc as well as in a Phase II trial in diabetic patients with NAFLD (non-alcoholic fatty liver disease).

About Inventiva
Inventiva is a biopharmaceutical company specialized in the development of drugs interacting with nuclear receptors, transcription factors and epigenetic modulators. Inventiva’s research engine opens up novel breakthrough therapies against fibrotic diseases, cancers and orphan diseases with substantial unmet medical needs.

Lanifibranor, its lead product, is an anti-fibrotic treatment acting on the three alpha, gamma and delta PPARs (peroxisome proliferator-activated receptors), which play key roles in controlling the fibrotic process. Its anti-fibrotic action targets two initial indications with substantial unmet medical need: NASH, a severe and increasingly prevalent liver disease already affecting over 30 million people in the United States, and systemic sclerosis, a disease with a very high mortality rate and for which there is no approved treatment to date.

Inventiva is also developing a second clinical program with odiparcil (IVA 336) for the treatment of patients with mucopolysaccaridosis type VI (or Maroteaux-Lamy syndrome), a rare and severe gene disease affecting children. Odiparcil has also the potential to address other MPS types, characterized by the accumulation of chondroitin or dermatan sulfate (MPS I or Hurler/Sheie syndrome, MPS II or Hunter syndrome, MPS IVa or Morquio syndrome and MPS VII or Sly syndrome). Inventiva is also developing a portfolio of early research projects in the field of oncology.

Inventiva benefits from partnerships with world-leading research entities such as the Institut Curie in the field of oncology. Two strategic partnerships have also been established with world-class major pharmaceutical companies AbbVie and Boehringer Ingelheim in the fields of autoimmune diseases (specifically in psoriasis) and fibrosis respectively. These partnerships provide milestone payments to Inventiva upon the achievement of pre-clinical, clinical, regulatory and commercial milestones, in addition to royalties on the products resulting from the partnerships.

Inventiva employs over 100 employees and owns R&D facilities near Dijon, acquired from the international pharmaceutical group Abbott. The Company owns, a proprietary chemical library of over 240,000 molecules as well as integrated biology, chemistry, ADME and pharmacology platforms.

Inventiva launches an independent working group to help increase NASH awareness and establish best practices for its treatment

Inventiva launches an independent working group to help increase NASH awareness and establish best practices for its treatment

September 24, 2018

Daix (France), September 24th, 2018 – Inventiva S.A. (“Inventiva” or the “Company”), a biopharmaceutical company developing innovative therapies in nonalcoholic steatohepatitis (NASH), systemic sclerosis (SSc) and mucopolysaccharidosis (MPS), announced today the creation of the panNASH?* initiative, a working group consisting of a committee of international independent experts that aims to increase the visibility and contribute to a better understanding of NASH, to share their expertise and to establish best practices for the treatment of the disease.

The initiative, which is supported by Inventiva, includes European and American medical experts in areas related to NASH such as hepatology, diabetes and cardiology, along with renowned scientific experts focused on promoting a better understanding of the physiopathological mechanisms involved in NASH (see the list of the founding members at the end of this press release);. Their aim will therefore be to play an active role in developing and disseminating their NASH expertise among the scientific community, patients and other key stakeholders within the healthcare system.

In particular, the experts group intends to help develop and share new findings about NASH through publications, conferences and training sessions. It will particularly focus on the development of the disease, the identification of patients at risk, clinical markers and associated health risks, as well as the development of new treatments. Specifically, the committee will help to increase knowledge of pathological mechanisms ranging from metabolic disorders to fibrosis and comorbidities, with a focus on the modulating role played by PPARs (peroxisome proliferator-activated receptors, subtypes).

Frédéric Cren, Chairman, Chief Executive Officer and co-founder of Inventiva, stated: “This working group brings together recognized NASH experts with unique and complementary skills and represents a further commitment by Inventiva to become a key player in the development of a treatment for this disease. I am confident that the program will lead to a better understanding of NASH by the various stakeholders. The group’s work will play a key role in establishing best practices for the treatment of NASH, a serious disease for which there is not yet any approved treatment, but which is one of society’s most widespread metabolic diseases, with 30 million patients already affected in the USA alone.”

The first meeting of the panNASH(TM) initiative took place in Geneva on September 22, 2018 following the NAFLD Summit 2018 ;organized by European Association for the Study of the Liver (EASL).

Inventiva advances in the development of lanifibranor with the achievement of three key milestones

August 30, 2018

> New patent granted by the USPTO protecting the use of lanifibranor in numerous fibrotic diseases

> Enrolment of first patient in the United States Phase II study for the treatment of NAFLD in patients with type 2 diabetes

> FDA approval of the IND application enabling to launch the clinical development plan in the United States

Daix (France), August 30, 2018 – Inventiva S.A. (“Inventiva” or the “Company”), a biopharmaceutical company developing innovative therapies in nonalcoholic steatohepatitis (NASH), systemic sclerosis (SSc) and mucopolysaccharidosis (MPS), today announced the successful completion of three key milestones in the development of its lead product, lanifibranor.

New patent granted by the USPTO protecting the use of lanifibranor in numerous fibrotic diseases

On August 21, 2018, the United States Patent and Trademark Office (USPTO) granted a new patent protecting until June 2035 the therapeutic use of lanifibranor in the treatment of various fibrotic conditions, including NASH and SSc.

This patent strengthens and extends in the United States the term of protection of lanifibranor derived from the New Chemical Entity (NCE) patent expiring in December 2031 (this expiration date includes a possible five-year extension to compensate for regulatory delays in obtaining the marketing approval).

Enrolment of the first patient in the United States Phase II study for the treatment of NAFLD in patients with type 2 diabetes

Following the agreement with the University of Florida to conduct a Phase II study in the United States with lanifibranor for the treatment of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes, the first of 64 patients for this study has been enrolled in August 2018. The recruitment of the other patients continues in accordance with the planned schedule and top line results are expected in early 2020.

The overall objective of the study , led by Dr Kenneth Cusi, Head of the Department of Endocrinology, Diabetes & Metabolism in the Department of Medicine at the University of Florida at Gainesville, is to measure the metabolic improvements induced by lanifibranor, as well as its effects on hepatic steatosis in patients with type 2 diabetes and NAFLD. In addition, this study will examine the impact of lanifibranor on fibrosis using the latest imaging and biomarker technologies.

FDA approval of the IND application enabling to launch the clinical development plan in the United States

On August 24, 2018, the Company received the approval of its IND (Investigational New Drug) application from the gastroenterology division of the FDA (Food and Drug Administration) for lanifibranor in order to conduct a drug interaction study required to pursue the development program.

This approval is an important milestone as it will allow Inventiva to use this IND to initiate further clinical studies for lanifibranor’s development in NASH in the United States.

Frédéric Cren, CEO and co-founder of Inventiva, said: “These three important achievements demonstrate the continued progress made in the clinical development of lanifibranor and confirm our confidence in the future of our lead product. The new patent granted by the USPTO is a tangible proof of the innovative nature of our therapeutic approach with lanifibranor and above all extends the date of exclusivity by several years.”;

Inventiva Announces Positive DSMB Reviews in both NASH and Systemic Sclerosis Phase IIb Trials with Lanifibranor

Inventiva Announces Positive DSMB Reviews in both NASH and Systemic Sclerosis Phase IIb Trials with Lanifibranor

July 10, 2018

> Both DSMB recommend trials to continue without changing the protocol

> Lanifibranor safety is confirmed

> Trials to continue as planned

Daix (France) June 20, 2018 – Inventiva S.A. (“Inventiva” or the “Company”), a biopharmaceutical company developing innovative therapies in nonalcoholic steatohepatitis (“NASH”), systemic sclerosis (“SSc”) and mucopolysaccharidosis (“MPS”), today announced that the FASST (For A Systemic Sclerosis Treatment) Data Safety Monitoring Board (“DSMB”) held its third and last meeting before the end of the trial of lanifibranor in SSc. Similarly to the conclusions of the first two DSMBs , the board recommended that the study continue without any modification to the protocol. Similarly the NATIVE (NASH Trial to Validate IVA337 Efficacy) DSMB met for the first time and after reviewing all safety data came to a similar conclusion and recommended to continue the study without any modification of the protocol. The positive outcomes of these two DSMBs confirm the good safety of lanifibranor, already demonstrated in long-term toxicological studies as well as in phase I and phase II clinical trials. Both studies are progressing as planned with no specific concerns and topline results are anticipated in early 2019 for the FASST trial in SSc and second half of 2019 for the NATIVE trial in NASH.

About Lanifibranor:

Lanifibranor is a next generation panPPAR modulator designed as a moderately potent and well balanced PPAR α, γ and δ. This unique profile was conceived in order to obtain an optimal therapeutic margin with strong efficacy and tolerance. Inventiva is currently evaluating lanifibranor in two parallel Phase IIb clinical studies in NASH and SSc.

About the Phase IIb FASST trial:

The Phase IIb FASST trial is a one-year randomized double-blind study designed to measure the effect of lanifibranor on the progression of systemic sclerosis (SSc). Patients will receive either lanifibranor or placebo according to the study protocol, approved by the European Medicines Agency (EMA). The primary endpoint is change in the Modified Rodnan Skin Score (MRSS), which is a measure of disease progression accepted by both Food and Drug Administration (FDA) and the EMA. Inclusion criteria are based on a MRSS between 10 and 25, and diffuse systemic sclerosis diagnosed from less than 3 years. Patients are allowed to continue their ongoing treatments, including immunosuppressive therapies. Lanifibranor has been granted orphan drug status for the treatment of systemic sclerosis by the EMA and the FDA. The orphan drug status provides certain advantages for the sponsor such as reduced procedure costs and commercial exclusivity.

About the Phase IIb NATIVE trial:

The Phase IIb NATIVE trial is a 24-week randomized double-blind study designed to assess the efficacy of lanifibranor on ballooning and inflammation without worsening of fibrosis. Patients will receive either lanifibranor or placebo. This trial will also evaluate the safety of lanifibranor treatment. The main inclusion and assessment criteria of the study are based on the hepatic histology of each patient: (i) NASH histological diagnosis according to the NASH Clinical Research Network criteria (steatosis, lobular inflammation of any degree and liver cell ballooning of any amount) and (ii) SAF activity score of 3 or 4 (> 2), SAF Steatosis score >= 1 and SAF Fibrosis score < 4. The primary endpoint of the study is a decrease in relation to the baseline of >= 2 points of the SAF activity score combining hepatocellular inflammatory and ballooning.

About Inventiva
Inventiva is a biopharmaceutical company specialized in the development of drugs interacting with nuclear receptors, transcription factors and epigenetic modulators. Inventiva’s research engine opens up novel breakthrough therapies against fibrotic diseases, cancers and orphan diseases with substantial unmet medical needs.

Lanifibranor, its lead product, is an anti-fibrotic treatment acting on the three alpha, gamma and delta PPARs (peroxisome proliferator-activated receptors), which play key roles in controlling the fibrotic process. Its anti-fibrotic action targets two initial indications with substantial unmet medical need: NASH, a severe and increasingly prevalent liver disease already affecting over 30 million people in the United States, and systemic sclerosis, a disease with a very high mortality rate and for which there is no approved treatment to date.

Inventiva is also developing a second clinical program with odiparcil (IVA 336) for the treatment of patients with mucopolysaccaridosis type VI (or Maroteaux-Lamy syndrome), a rare and severe gene disease affecting children. Odiparcil has also the potential to address other MPS types, characterized by the accumulation of chondroitin or dermatan sulfate (MPS I or Hurler/Sheie syndrome, MPS II or Hunter syndrome, MPS IVa or Morquio syndrome and MPS VII or Sly syndrome). Inventiva is also developing a portfolio of early research projects in the field of oncology.

Inventiva benefits from partnerships with world-leading research entities such as the Institut Curie in the field of oncology. Two strategic partnerships have also been established with world-class major pharmaceutical companies AbbVie and Boehringer Ingelheim in the fields of autoimmune diseases (specifically in psoriasis) and fibrosis respectively. These partnerships provide milestone payments to Inventiva upon the achievement of pre-clinical, clinical, regulatory and commercial milestones, in addition to royalties on the products resulting from the partnerships.

Inventiva employs over 100 employees and owns R&D facilities near Dijon, acquired from the international pharmaceutical group Abbott. The Company owns, a proprietary chemical library of over 240,000 molecules as well as integrated biology, chemistry, ADME and pharmacology platforms.

FDA Approval of an Investigator Initiated IND Application to Conduct Phase II Study of Lanifibranor in Type 2 Diabetic Patients with Non-Alcoholic Fatty Liver Disease

June 20, 2018

> Study to enroll first patient in the third quarter 2018 with topline results expected early 2020

> FDA approval is a positive signal for SSc and NASH IND applications

Daix (France) June 20, 2018 – Inventiva S.A. (“Inventiva” or the “Company”), a biopharmaceutical company developing innovative therapies in nonalcoholic steatohepatitis (NASH), systemic sclerosis (SSc) and mucopolysaccharidosis (MPS), today announced that the U.S. Food and Drug Administration (FDA) has accepted the investigator initiated Investigational New Drug (IND) application providing clearance to proceed with the Phase II study of lanifibranor in type 2 diabetic patients with nonalcoholic fatty liver disease (NAFLD). This FDA approval is also a positive signal for the planned Company IND applications in SSc and NASH.

The trial to be conducted by Dr. Kenneth Cusi, Chief of the Division of Endocrinology, Diabetes & Metabolism in the Department of Medicine at the University of Florida, Gainesville, is expected to enroll 64 patients treated for a 24-week period with a single daily dose of lanifibranor (800 mg/day) or placebo and 10 subjects in a healthy, non-obese control group. The study’s overall objective is to measure the metabolic improvements induced by lanifibranor, and its effect on steatosis in type 2 diabetic patients with NAFLD. Additionally, this study will detect lanifibranor’s impact on fibrosis using the most recent imaging and biomarker technology. Its main endpoints are a decrease of liver steatosis assessed by state-of-the-art imaging, including H-MRS (Proton Magnetic Resonance Spectroscopy), a decrease of insulin resistance (glucose clamp, HBA1c), a decrease in de novo lipogenesis, and safety. The first patient is expected to be enrolled in the third quarter of 2018 and topline results are expected beginning of 2020.

“With its unique pan-PPAR profile, lanifibranor has shown very good safety features, relevant efficacy data in NASH preclinical models as well as positive metabolic effects in a Phase IIa study in diabetic patients,” Dr. Cusi said. “We anticipate the results of this study to translate well to diabetic patients with NAFLD or NASH and look forward to demonstrating that lanifibranor could become a very valuable drug for these patients.”

Jean-Louis Abitbol, MD, MSC, Chief Medical Officer of Inventiva, added: “We are delighted that the FDA has allowed Dr Cusi and his team to proceed with this exciting metabolic and imaging study and we very much look forward to the enrollement of US patients as these results will provide additional supporting data for our regulatory filings with US and European regulators.”

Inventiva Announces a U.S. Phase II Investigator-Initiated Study with Lanifibranor on Non-Alcoholic Fatty Liver Disease in Patients with Type 2 Diabetes

April 03, 2018

Dr. Kenneth Cusi of the University of Florida to be principal investigator
Trial in 64 patients to begin after the FDA has approved lanifibranor IND

Daix (France), April 3rd, 2018 – Inventiva, a biopharmaceutical company developing innovative therapies in nonalcoholic steatohepatitis (NASH), systemic sclerosis (SSc) and mucopolysaccharidosis (MPS), today announced that Dr. Kenneth Cusi, Chief of the Division of Endocrinology, Diabetes & Metabolism in the Department of Medicine at the University of Florida, Gainesville, has selected lanifibranor for a Phase II investigator-initiated clinical trial. The trial’s objective is to evaluate the efficacy and safety of lanifibranor on intrahepatic triglycerides and hepatic insulin sensitivity in type 2 diabetic patients with nonalcoholic fatty liver disease (NAFLD). A positive result would further reinforce lanifibranor as the ideal drug for NAFLD and NASH patients with type 2 diabetes (T2DM).

Lanifibranor is a new generation panPPAR agonist that activates the alpha, gamma and delta isoforms of the peroxisome proliferator-activated receptors (PPARs). Lanifibranor selection for this study was motivated by this unique mechanism of action that can potentially address all key features of NAFLD and NASH: improvement of insulin-sensitivity, steatosis reduction, anti-inflammatory activity and reduction of fibrosis. In parallel to this investigator-initiated study, Inventiva is currently conducting two lanifibranor Phase IIb clinical trials in NASH and SSc. The Company has been granted orphan drug designation for lanifibranor by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) in SSc.

“PPARs are clinically validated targets to treat patients suffering from NAFLD or NASH. Lanifibranor with its moderate and balanced panPPAR profile and its gamma activity, is a very promising candidate adressing most if not all the components of NASH” Dr. Cusi said. “We anticipate this profile will translate well into type 2 diabetic patients affected by NAFLD or NASH and are confident in the success of this trial.”

Jean-Louis Abitbol, MD, MSC, Chief Medical Officer of Inventiva, said: “We are delighted that Dr. Cusi, a renowned expert in the PPAR field and world-class clinician has selected lanifibranor for this study that will provide us with additional supportive data for our regulatory filings of lanifibranor with U.S. and European regulators.”;

Pierre Broqua, Chief Scientific Officer and a co-founder of Inventiva, added: “We are extremely excited by this collaboration with Dr Cusi. This study meets several of our strategic objectives with a contained financial investment, including opening an IND1, initiating a study in the US in a population likely to benefit from lanifibranor treatment and enlarge the clinical data package for future interactions with FDA.”;

The trial conducted by Dr. Cusi is expected to enroll 64 patients treated for a 24-week period with a single daily dose of lanifibranor (800mg/day) and 10 subjects in a healthy, non-obese control group. The study’s overall objective is to measure the metabolic effects of lanifibranor, and its potential efficacy on steatosis in T2DM patients with NAFLD. Additionally this study will detect lanifibranor impact on fibrosis using the most recent imaging technology. The main endpoints are a decrease of liver steatosis assessed by state of the art imaging, including H-MRS (Proton Magnetic Resonance Spectroscopy), evidence of metabolic improvements in insulin resistance (glucose clamp, HBA1c), de novo lipogenesis, free fatty acids, lipids and safety. The trial should begin in Q2/Q3 2018 depending on FDA approval of lanifibranor IND filing.

Inventiva Announces Presentation of Preclinical Results on IVA337 in NASH at the International Liver Congress™ 2017 (EASL)

Inventiva Announces Presentation of Preclinical Results on IVA337 in NASH at the International Liver Congress™ 2017 (EASL)

April 20, 2017

Daix (France), April 20, 2017 – 07:30 am CEST – Inventiva, a biopharmaceutical company developing innovative therapies, particularly to treat fibrosis, announced today the presentation of a poster on its lead drug candidate IVA337 at the 2017 International Liver Congress? annual meeting of the European Association for the Study of the Liver, currently being held in Amsterdam. The poster entitled “IVA337, a Pan-PPAR Agonist, Reduces NASH Features and Inhibits the Inflammasome in Murine Models of NASH” ;authored by Guillaume Wettstein, et al;, discussed the effect of IVA337 in two mechanistically different preclinical models of nonalcoholic steatohepatitis (NASH) and studied its effect on crucial pathways implicated in NASH and fibrosis development.

“The results of this preclinical study further confirm the potential of IVA337 as a treatment for NASH,” said Dr. Pierre Broqua, Chief Scientific Officer and Cofounder of Inventiva. “The findings demonstrate that IVA337 inhibits the development of NASH through the normalization of different metabolic parameters such as insulin-resistance, through activation of fatty acid ?-oxidation, and inhibition of the inflammasome known to be a trigger of liver inflammation and fibrosis.”

Study Design and Results

  1. C57bl/6 mice were fed for 3 weeks with methionine-choline deficient (MCD) diet and simultaneously treated with IVA337

  2. Foz/foz mice received a high fat diet (HFD) for 6 weeks to initiate NASH pathology and were kept under HFD alone or in combination with IVA337 for another 6 weeks.

IVA337 Activity in the Methionine-Choline Deficient Diet Model

IVA337 inhibits steatosis, inflammation, and the expression of pro-fibrotic genes, and improved global liver condition.

IVA337 Activity in the foz/foz Model

  • IVA337 has no effect on food intake or weight, quickly normalizes glycemia and improves glucose tolerance.

  • IVA337 restores insulin sensitivity

  • IVA337 improves NASH features – steatosis, ballooning, and inflammation were reduced compared to the HFD control group.

  • IVA337 inhibits the expression of pro-fibrotic genes

In both models, IVA337 demonstrated positive effects on the biological pathways that are altered during NASH development. Specifically, IVA337 decreased the expression of the inflammasome components such as caspase 1, IL-1 et IL-18 in both models, and activated the expression of genes regulating fatty acid catabolism. IVA337 also decreased the expression of inflammatory factors such as CCR2, CCL5 and NFKB.

About the International Liver CongressTM

Inventiva Announces Initiation of Phase IIb Clinical Trial of IVA337 for Treatment of Non-Alcoholic Steatohepatitis (NASH)

Inventiva Announces Initiation of Phase IIb Clinical Trial of IVA337 for Treatment of Non-Alcoholic Steatohepatitis (NASH)

January 03, 2017

> Therapeutic candidate IVA337 is a next generation PanPPAR agonist addressing all the relevant clinical and regulatory features of NASH

> NATIVE clinical study plans to enroll 225 patients in 12 European countries

> Headline results are expected mid-2018

Daix, France, January 3, 2017 – Inventiva, an emerging biopharmaceutical company developing innovative therapies notably to treat fibrosis, today announces the beginning of patient enrollment for its Phase IIb clinical trial (NATIVE – NASH Trial to Validate IVA337 Efficacy) evaluating the Company’s lead compound, IVA337, for the treatment of Non-Alcoholic Steatohepatitis (NASH). “Unlike other drugs targeting NASH, IVA337, a next generation PanPPAR agonist, addresses all the relevant clinical and regulatory features of this condition: steatosis, inflammation, ballooning and fibrosis.” said Pierre Broqua, co-founder and Chief Scientific Officer of Inventiva.

NASH is a severe and chronic form of non-alcoholic fatty liver disease that has become a leading cause to the need for liver transplantation. NASH affects over 30 million people in the United States1 , increases 5 to 10 fold the risk of liver related mortality and is expected to become the leading cause of liver transplantation by 2020. There are no pharmaceutical treatments currently approved and treatment options are limited to lifestyle changes, weight loss and or medical procedures, such as bariatric surgery.

NATIVE is a randomized, double-blind, placebo-controlled, multi-center, Phase IIb clinical trial in NASH patients. The study will investigate the safety and efficacy of two doses of IVA337 (800 and 1200 mg/day) over a 24-week period and will enroll up to 225 patients in 12 European countries. The primary endpoint will be based on histologically assessed improvement of the activity component of the SAF2 score combining inflammation and ballooning, without worsening of fibrosis.

“NASH is a highly prevalent condition with a significant unmet medical need,” said Prof Sven Francque of the Antwerp University Hospital, and one of the trial’s Principal Investigators. “The medical community is in search of a treatment that resolves NASH without worsening fibrosis. Based on the data generated in pre- clinical models, IVA337 has the potential to meet this objective. Therefore, we are excited to further evaluate IVA337 in this Phase IIb clinical trial.”

“We are very pleased with the progress so far and the positive feed-back received from regulatory agencies as well as from the clinicians involved in the study: we look forward to the full enrollment of this study in the second half of 2017” said Dr Jean-Louis Abitbol, Inventiva’s CMO.

IVA337 which has demonstrated anti-fibrotic properties in several tissues alongside good clinical tolerance is currently in a Phase IIb trial for the treatment of systemic sclerosis, another fibrotic disease with very high unmet medical needs. IVA337 has undergone a successful Phase IIa study in diabetic patients with improvements in markers of insulin resistance (HOMA-IR), and dyslipidemia (increase in circulating HDL cholesterol and decrease of circulating triglycerides). These clinical findings are extremely valuable as the physiopathology of NASH is intimately linked to obesity, IR and T2DM. Furthermore data generated in multiple relevant pre-clinical models demonstrated that IVA337 also positively impacts all hepatic lesions associated with NASH. In these pre-clinical studies, IVA337 significantly reduced steatosis, ballooning and inflammation, and reversed established liver fibrosis.

“This is a very important study in identifying a new treatment for NASH, a condition associated with increased mortality, with excess cardiovascular-, liver- and cancer-related deaths,” added Pierre Broqua. “Importantly, by measuring the efficacy of IVA337 on histological scores for ballooning and inflammation, the NATIVE study will evaluate the effects of IVA337 on the two components defining NASH resolution, a regulatory approved endpoint. The initiation of this study represents a critical milestone for our company as we continue to advance our diversified pipeline.”

2 SAF is a scoring system to measure liver lesions that dissociates grade of steatosis, grade of activity, and stage of fibrosis thus enabling an easy comparison between biopsies and changes observed in paired biopsies during clinical trials.

About Inventiva
Inventiva is a biopharmaceutical company specialized in the development of drugs interacting with nuclear receptors, transcription factors and epigenetic modulators. Inventiva’s research engine opens up novel breakthrough therapies against fibrotic diseases, cancers and orphan diseases with substantial unmet medical needs.

Lanifibranor, its lead product, is an anti-fibrotic treatment acting on the three alpha, gamma and delta PPARs (peroxisome proliferator-activated receptors), which play key roles in controlling the fibrotic process. Its anti-fibrotic action targets two initial indications with substantial unmet medical need: NASH, a severe and increasingly prevalent liver disease already affecting over 30 million people in the United States, and systemic sclerosis, a disease with a very high mortality rate and for which there is no approved treatment to date.

Inventiva is also developing a second clinical program with odiparcil (IVA 336) for the treatment of patients with mucopolysaccaridosis type VI (or Maroteaux-Lamy syndrome), a rare and severe gene disease affecting children. Odiparcil has also the potential to address other MPS types, characterized by the accumulation of chondroitin or dermatan sulfate (MPS I or Hurler/Sheie syndrome, MPS II or Hunter syndrome, MPS IVa or Morquio syndrome and MPS VII or Sly syndrome). Inventiva is also developing a portfolio of early research projects in the field of oncology.

Inventiva benefits from partnerships with world-leading research entities such as the Institut Curie in the field of oncology. Two strategic partnerships have also been established with world-class major pharmaceutical companies AbbVie and Boehringer Ingelheim in the fields of autoimmune diseases (specifically in psoriasis) and fibrosis respectively. These partnerships provide milestone payments to Inventiva upon the achievement of pre-clinical, clinical, regulatory and commercial milestones, in addition to royalties on the products resulting from the partnerships.

Inventiva employs over 100 employees and owns R&D facilities near Dijon, acquired from the international pharmaceutical group Abbott. The Company owns, a proprietary chemical library of over 240,000 molecules as well as integrated biology, chemistry, ADME and pharmacology platforms.
