• The first patient was randomized in China in the NATiV3 Phase III clinical trial, triggering a milestone payment of $3 million from CTTQ to Inventiva. 

• With this milestone payment Inventiva expects to have met the operational and financial conditions precedent to draw the second €25 million tranche of the EIB loan.¹

• China’s National Medical Products Administration has granted “Breakthrough Therapy Designation” to lanifibranor for the treatment of NASH. Lanifibranor is believed to be the first drug candidate to receive such designation from both the FDA and the NMPA.

• As of December 20, 2023, a total of 793 patients have been randomized in NATiV3 of which 657 in the main cohort and 136 in the exploratory cohort. 607 patients are currently in the screening process.

• The last patient first visit in the NATiV3 Phase III clinical trial is now expected in the first quarter of 2024, and the target number of randomized patients in the main cohort is expected to be reached in the second quarter of 2024.

• Analysis of the baseline characteristics of all patients randomized in the main cohort suggests a patient profile aligned with those of patients randomized in the NATIVE Phase II clinical trial.

• Lanifibranor continues to show a favorable tolerability profile as confirmed by the third Data Monitoring Committee² of November 2023.

• Topline results of the proof-of-concept Phase II clinical trial, LEGEND, evaluating lanifibranor in combination with empagliflozin are expected in the first quarter of 2024.

Milestone payment from CTTQ and EIB loan

Following the randomization of the first patient in China, Inventiva is eligible to receive a $3 million milestone payment from Chia Tai Tianqing Pharmaceutical Group Co., Ltd. (“CTTQ”). This would be the second of the two short-term milestone payments following the $2 million milestone payment from CTTQ received on July 19, 2023, under the license and collaboration agreement with CTTQ. Upon the anticipated receipt in January 2024 of this $3 million milestone, Inventiva is expected to have met all financial and operational conditions precedent required to draw the second €25 million tranche under the finance contract with the European Investment Bank (“EIB”) dated May 16, 2022 (the "Finance Contract"). The Company expects to draw this second tranche in early 2024, following the issuance of warrants to the EIB as provided in the Finance Contract.

Breakthrough Therapy Designation for lanifibranor in NASH by China’s NMPA

Lanifibranor was granted Breakthrough Therapy Designation for NASH by China’s National Medical Products Administration (NMPA). Similar to the U.S. Food and Drug Administration’s (FDA) Breakthrough Therapy Designation, this designation is intended to accelerate the development and review of drugs for serious or life-threatening conditions. The NMPA granted “Breakthrough Therapy Designation” based on the results of Inventiva's Phase IIb NATIVE clinical trial. Inventiva believes that lanifibranor is the first drug candidate to receive “Breakthrough Therapy Designation” from both the FDA and the NMPA for the treatment of NASH.

NATiV3  update

Frederic Cren, CEO and co-founder of Inventiva said: ”While we are not reaching the first visit of the last patient by the end of 2023 as previously projected, the improvements in the randomization, screening numbers and screen failure rate give us confidence that we can reach this milestone in the first quarter of 2024. The recommendation of our third Data Monitoring Committee (DMC) in November 2024² to continue the trial without modification to the protocol is further confirmation of the good safety profile of lanifibranor. Furthermore, we have high hopes that the results of the LEGEND trial will show benefit of the combination of lanifibranor with empagliflozin in patients with NASH.”

As of December 20, 2023, 468 clinical sites have been activated in 24 countries, including China, and a total of 793 patients have been randomized, of which 657 in the main cohort and 136 in the exploratory cohort. 607 patients are in the screening process and, based on the recent screen failure rate of approximately 80%, Inventiva expects 121 additional patients to be randomized in the main cohort in the next 10 weeks.

Since July, with limited contribution from the sites in China, the newly opened sites and a third party clinical network in Mexico, between 250 to 300 patients are screened and approximately 50 patients are randomized in the main cohort each month, and the monthly enrolment rate is averaging 0.14 patient/site/month in the main cohort. Therefore, if the current screen failure rate for the main cohort and the number of patients entering the screening process are maintained, Inventiva now expects the first visit of the last patient to be in the first quarter of 2024 and to complete randomization in the second quarter of 2024.

Topline results for the Phase III NATiV3 clinical trial are now expected to be published in the first half of 2026 versus the second half of 2025, as previously communicated.

If the results of the trial confirm sufficient clinical benefit and a continued good safety profile, Inventiva plans to submit an application for accelerated approval in the United States and conditional approval in the European Union for the marketing of lanifibranor. In addition, CTTQ would also be in capacity to submit an application for a marketing authorization in Greater China.

NATiV3 patients distribution and characteristic

Approximately 70% of the patients randomized in the main and exploratory cohorts are from the United States, ~20% from Europe and ~10% from Latin America and the rest of the world.
At baseline, 13% of patients randomized in the main cohort are receiving a stable dose GLP1 receptor agonists and 8% are receiving stable SGLT2 inhibitors.
The baseline characteristics of the patients enrolled so far in the main cohort are in line with expectations and the patient population in the NATIVE Phase IIb clinical trial. The main difference in patient characteristics observed thus far is that there is a higher percentage of patients with type 2 diabetes (T2D) in the main cohort of the NATiV3 Phase III trial compared to the NATIVE Phase IIb trial (55% vs 42%, respectively). The effect size of lanifibranor therapy over placebo in the Phase IIb clinical trial on the composite endpoint “NASH resolution and fibrosis improvement” (which corresponds to the primary efficacy endpoint in the NATiV3 Phase III clinical trial), was higher in patients with T2D than in patients without diabetes: 21% and 26% for lanifibranor 800 and 1200 mg/day, respectively, in patients with T2D compared to 7% and 22%, respectively, in patients without T2D. Given the higher risk of hepatic and extrahepatic morbidity in patients with T2D and NASH³, the higher effect size observed in patients with NASH and T2D treated with lanifibranor in the Phase IIb trial is an important result for this specific patient population if confirmed in the larger clinical trial.

As of December 20, 2023, 136 patients are randomised in the exploratory cohort including approximately 30% of  patients with fibrosis stage F4. Inventiva believes that this subgroup of patients will provide valuable data on lanifibranor efficacy and safety.

Lanifibranor continues to show a favorable tolerability profile as confirmed by the third Data Monitoring Committee (DMC) that took place late November 2023². This safety assessment was based on the review of safety data from more than 500 patients, including patients that have been treated with lanifibranor for more than 72 weeks.

Update on Phase II clinical trial LEGEND

Enrolment in the proof of concept, LEGEND Phase II clinical trial evaluating lanifibranor in combination with the SGLT2 inhibitor empagliflozin in patients with NASH has been stopped, and data collection and cleaning is ongoing. The first topline results on primary and secondary endpoints are expected for the end of the first quarter of 2024. The primary efficacy endpoint of the trial is a change in Hemoglobin A1c (“HbA1c”) at the end of the 24-week treatment compared to baseline. Secondary endpoints include changes in liver enzymes, glycaemic and lipids parameters, and inflammatory markers. The trial has been designed to provide valuable information on body weight evolution in patients with NASH and T2D when treated with lanifibranor and empagliflozin, and on the reduction of hepatic steatosis using magnetic resonance imaging (MRI).
