Bayer to Present Data From Cardiovascular Portfolio, Including a Late-Breaking Presentation From FIDELITY for KERENDIA® (finerenone) and New Phase IIb Data From PACIFIC Trial Program for the Oral Factor XIa Inhibitor asundexian

WHIPPANY, N.J.–()–Bayer will present a range of new clinical data at the European Society of Cardiology’s 70th Annual Scientific Session (ESC.22) from August 26-29. Three late-breaking abstracts will be presented including data on the nonsteroidal mineralocorticoid receptor (MR) antagonist, KERENDIA® (finerenone),1 and the investigational oral Factor XIa inhibitor, asundexian. These data highlight Bayer’s ongoing commitment to patients with cardiovascular (CV) and kidney diseases.

Finerenone Prespecified Pooled Analysis FIDELITY Data

The prespecified exploratory pooled analysis FIDELITY, pools data from the FIDELIO-DKD and FIGARO-DKD Phase III studies, comprises data from more than 13,000 patients with chronic kidney disease (CKD) associated with type 2 diabetes (T2D).2

A new exploratory analysis of FIDELITY, investigating causes of mortality in patients with CKD associated with T2D treated with finerenone or placebo, will be presented within the following late-breaking live-streamed session:

Additional sub-analysis from FIDELITY will evaluate whether CKD, as defined jointly by estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR), is a modifiable CV risk factor in patients with T2D. This sub-analysis will be presented during the following moderated ePosters session:

KERENDIA was approved in the United States based on the results of FIDELIO-DKD, to reduce the risk of sustained eGFR decline, end-stage kidney disease, CV death, nonfatal myocardial infarction and hospitalization for heart failure in adult patients with CKD associated with T2D.1 The KERENDIA label contains a Warning and Precaution that KERENDIA can cause hyperkalemia.1 For more information, see Important Safety Information below.

Asundexian PACIFIC Phase IIb Study Data

The PACIFIC Phase IIb clinical program was designed to investigate if asundexian can reduce the risk of thrombotic events while minimizing additional bleeding risk. The PACIFIC Phase II clinical trial program consisted of three Phase IIb studies, each one focusing on one of the following medical conditions: atrial fibrillation (irregular heartbeat),3 a recent non-cardioembolic ischemic stroke4 or a recent acute myocardial infarction (heart attack).5

PACIFIC-AMI is a Phase IIb dose-finding trial which compares the investigational, oral FXIa inhibitor asundexian to placebo on top of standard dual antiplatelet therapy (DAPT) in patients following an acute myocardial infarction (AMI, or heart attack).5 The study was designed to evaluate the effect of several different doses of asundexian on safety (bleeding) and efficacy (cardiovascular death, myocardial infarction, stroke and stent thrombosis) versus placebo, on top of DAPT.5 The results of the study will be presented within the following late-breaker live-streamed session:

PACIFIC-STROKE is a Phase IIb dose-finding trial designed to evaluate the effect of several different doses of asundexian on safety (bleeding) and efficacy on top of the standard anti-platelet therapy in patients following a non-cardioembolic ischemic stroke compared to a placebo.4 The results of the study will be presented within the following late-breaker live-streamed session:

In addition to the release of this study data, a joint session with ESC and The Lancet will review PACIFIC-AF, a Phase IIb dose-finding study comparing the safety (bleeding) of the oral FXIa inhibitor asundexian to the non-vitamin K antagonist oral anticoagulant (NOAC) apixaban in patients with irregular heartbeat (atrial fibrillation [AF]) who are at risk of stroke.3 The results were previously presented at the American College of Cardiology’s 71st Annual Scientific Session & Expo.

An additional poster presentation on the complete bioavailability of asundexian will also be presented during the congress:

About KERENDIA (finerenone)


  • KERENDIA is indicated to reduce the risk of sustained eGFR decline, end-stage kidney disease, cardiovascular death, nonfatal myocardial infarction, and hospitalization for heart failure in adult patients with chronic kidney disease (CKD) associated with type 2 diabetes (T2D)1



  • Concomitant use with strong CYP3A4 inhibitors1
  • Patients with adrenal insufficiency1


  • Hyperkalemia: KERENDIA can cause hyperkalemia. The risk for developing hyperkalemia increases with decreasing kidney function and is greater in patients with higher baseline potassium levels or other risk factors for hyperkalemia. Measure serum potassium and eGFR in all patients before initiation of treatment with KERENDIA and dose accordingly. Do not initiate KERENDIA if serum potassium is >5.0 mEq/L1

    Measure serum potassium periodically during treatment with KERENDIA and adjust dose accordingly. More frequent monitoring may be necessary for patients at risk for hyperkalemia, including those on concomitant medications that impair potassium excretion or increase serum potassium1


  • Adverse reactions reported in ≥1% of patients on KERENDIA and more frequently than placebo: hyperkalemia (18.3% vs. 9%), hypotension (4.8% vs. 3.4%), and hyponatremia (1.4% vs. 0.7%)1


  • Strong CYP3A4 Inhibitors: Concomitant use of KERENDIA with strong CYP3A4 inhibitors is contraindicated. Avoid concomitant intake of grapefruit or grapefruit juice1
  • Moderate and Weak CYP3A4 Inhibitors: Monitor serum potassium during drug initiation or dosage adjustment of either KERENDIA or the moderate or weak CYP3A4 inhibitor and adjust KERENDIA dosage as appropriate1
  • Strong and Moderate CYP3A4 Inducers: Avoid concomitant use of KERENDIA with strong or moderate CYP3A4 inducers1


  • Lactation: Avoid breastfeeding during treatment with KERENDIA and for 1 day after treatment1
  • Hepatic Impairment: Avoid use of KERENDIA in patients with severe hepatic impairment (Child Pugh C) and consider additional serum potassium monitoring with moderate hepatic impairment (Child Pugh B)1

Please read the Prescribing Information for KERENDIA.

About Chronic Kidney Disease Associated With Type 2 Diabetes

Patients with CKD associated with T2D are three times more likely to die from a CV-related cause than those with T2D alone.6 CKD is a serious and progressive condition that is generally underrecognized.7 CKD is a frequent complication arising from T2D and is also an independent risk factor of CV disease.8-10 Approximately 40% of all patients with T2D develop CKD.10 Despite guideline-directed therapies, patients with CKD associated with T2D remain at high risk of CKD progression and CV events.8,9,11,12 T2D is the leading cause of end-stage kidney disease, which requires dialysis or a kidney transplant to stay alive.13-15

About Factor XI and FXIa Inhibitors (asundexian)

Asundexian* (BAY2433334) is an investigational oral Factor XIa (FXIa) inhibitor (anti-thrombotic) and is part of a portfolio of assets targeting FXI or FXIa currently in clinical development by Bayer. Asundexian is currently being studied in the PACIFIC Phase IIb clinical trial program that consists of three Phase IIb studies in over 4,000 patients with one of the following three medical conditions: atrial fibrillation (irregular heartbeat)3, a recent non-cardioembolic ischemic stroke4 or a recent myocardial infarction (heart attack).5 Asundexian is an investigational agent and has not been approved by any health authority for use in any country, for any indication.
