FDA Approves BAVENCIO® (avelumab) Plus INLYTA® (axitinib) Combination for Patients with Advanced Renal Cell Carcinoma

Not intended for UK-based media

  • BAVENCIO is the first anti-PD-L1 in combination with INLYTA approved by FDA for first-line treatment of patients with advanced renal cell carcinoma (RCC)
  • Phase III study showed combination significantly lowered risk of disease progression or death by 31% and extended progression-free survival by 5.4 months for patients with advanced RCC compared with sunitinib
  • Combination approved based on Phase III data in an overall population that included patients regardless of PD-L1 expression and across favorable, intermediate and poor prognostic groups
  • Additional regulatory reviews for BAVENCIO plus INLYTA in advanced RCC are underway worldwide, including in the European Union and Japan

Darmstadt, Germany and New York, US, May 14, 2019 - Merck KGaA, Darmstadt, Germany, which operates its biopharmaceutical business as EMD Serono in the US and Canada, and Pfizer Inc. (NYSE: PFE) today announced that the US Food and Drug Administration (FDA) has approved BAVENCIO® (avelumab) in combination with INLYTA® (axitinib) for the first-line treatment of patients with advanced renal cell carcinoma (RCC). This is the first FDA approval for an anti-PD-L1 therapy as part of a combination regimen for patients with advanced RCC. The approval of BAVENCIO in combination with INLYTA was based on positive results from the Phase III JAVELIN Renal 101 study (NCT02684006), in which the combination significantly improved median progression-free survival (PFS) compared with sunitinib by more than five months in the intent-to-treat (ITT) patient population (HR: 0.69 [95% CI: 0.56-0.84]; 2-sided p-value=0.0002; median PFS for BAVENCIO in combination with INLYTA: 13.8 months [95% CI: 11.1-NE]; sunitinib: 8.4 months [95% CI: 6.9-11.1]). The ITT population included patients regardless of PD-L1 expression and across IMDC (International Metastatic Renal Cell Carcinoma Database) prognostic risk groups (favorable 21%, intermediate 62% and poor 16%).1

'As we look to continue to improve outcomes for people with advanced RCC, new treatment approaches have the potential to benefit patients,' said Robert J. Motzer, M.D., Jack and Dorothy Byrne Chair in Clinical Oncology, Memorial Sloan Kettering Cancer Center, New York, US, and principal investigator for JAVELIN Renal 101. 'With today's FDA approval of avelumab in combination with axitinib, we can now offer patients with advanced RCC a first-line treatment option that combines a PD-L1 immunotherapy with a well-known VEGFR TKI to provide a significant reduction in the risk of disease progression or death and doubling of the response rate compared with sunitinib.'

RCC is a type of cancer where PD-L1 expression may contribute to inhibition of the immune response against the tumor.2 It is also a highly vascular tumor, in which vascular endothelial growth factor (VEGF) plays a key role.3

'A kidney cancer diagnosis is life-changing for both patients and their loved ones, and having a treatment strategy for their disease quickly becomes a priority,' said Dena Battle, President, KCCure. 'The approval of new treatments such as BAVENCIO in combination with INLYTA gives patients with advanced RCC much-needed options.'

There is a significant unmet need for first-line treatments that delay progression and have an acceptable safety profile. Approximately 20% to 30% of patients are first diagnosed with RCC at the advanced stage, and 30% of patients treated for an earlier stage go on to develop metastases.4,5 About half of patients living with advanced RCC do not go on to receive additional treatment after first-line therapy,6,7 for reasons that may include poor performance status or adverse events from their initial treatment.6,8,9

'Today's approval of BAVENCIO in combination with INLYTA builds on Pfizer's long heritage in bringing innovation to the RCC community with the hopes of making a significant and meaningful impact on the lives of patients,' said Andy Schmeltz, Global President, Pfizer Oncology. 'For more than 12 years, Pfizer has led the field in its commitment to developing new treatments for patients with advanced kidney cancer.'

'With today's FDA approval of BAVENCIO in combination with INLYTA, we feel privileged that we can offer patients with first-line advanced renal cell carcinoma a new treatment option,' said Rehan Verjee, President, EMD Serono, and Global Head of Innovative Medicine Franchises, Merck KGaA, Darmstadt, Germany.

In JAVELIN Renal 101, the objective response rate (ORR) was doubled in the ITT population with BAVENCIO in combination with INLYTA versus sunitinib (51.4% [95% CI: 46.6-56.1] vs. 25.7% [95% CI: 21.7-30.0]). With a median overall survival (OS) follow-up of 19 months, data for the trial's other primary endpoint of OS were immature, with 27% of deaths in the ITT population, and the trial is continuing as planned. The most common adverse reactions (≥20%) were diarrhea, fatigue, hypertension, musculoskeletal pain, nausea, mucositis, palmar-plantar erythrodysesthesia, dysphonia, decreased appetite, hypothyroidism, rash, hepatotoxicity, cough, dyspnea, abdominal pain and headache. Serious adverse reactions occurred in 35% of patients receiving BAVENCIO in combination with INLYTA. The incidence of major adverse cardiovascular events (MACE) was higher with BAVENCIO in combination with INLYTA versus sunitinib.1 Findings from the study have been published in The New England Journal of Medicine.10

The European Medicines Agency (EMA) validated the Type II variation application for BAVENCIO in combination with INLYTA in advanced RCC in March 2019, and a supplemental application for BAVENCIO in combination with INLYTA in unresectable or metastatic RCC was submitted in Japan in January 2019.

Each program will independently conduct the access and reimbursement activities for the product for which it is responsible.

About Renal Cell Carcinoma

In 2019, an estimated 73,820 new cases of kidney cancer will be diagnosed in the US, and approximately 14,770 people will die from the disease.11 RCC is the most common form of kidney cancer, accounting for about 2% to 3% of all cancers in adults.12,13 Approximately 20% to 30% of patients with kidney cancer are first diagnosed at the advanced stage.4 The five-year survival rate for patients with metastatic RCC is approximately 12%.14

About the JAVELIN Renal 101 study

The Phase III JAVELIN Renal 101 study is a randomized (1:1), multicenter, open-label study of BAVENCIO in combination with INLYTA in 886 patients with untreated advanced RCC regardless of tumor PD-L1 expression [intent-to-treat (ITT) population]. Patients with autoimmune disease or conditions requiring systemic immunosuppression were excluded. The major efficacy outcome measures were PFS as assessed by a Blinded Independent Central Review (BICR) using RECIST v1.1 and OS in patients with PD-L1-positive tumors using a clinical trial assay (PD-L1 expression level ≥1%). If PFS was statistically significant in patients with PD-L1-positive tumors, it was then tested in the ITT population. The hazard ratio for PFS in patients with PD-L1-positive tumors was HR 0.61 (95% CI: 0.48, 0.79). PFS and OS in the ITT population, overall response and safety are included as secondary endpoints. The study is continuing for OS.

About the JAVELIN Clinical Development Program

The clinical development program for avelumab, known as JAVELIN, involves at least 30 clinical programs and about 10,000 patients evaluated across more than 15 different tumor types. In addition to RCC, these tumor types include gastric/gastro-esophageal junction cancer, head and neck cancer, Merkel cell carcinoma, non-small cell lung cancer, and urothelial carcinoma.

About BAVENCIO® (avelumab)

BAVENCIO is a human anti-programmed death ligand-1 (PD-L1) antibody. BAVENCIO has been shown in preclinical models to engage both the adaptive and innate immune functions. By blocking the interaction of PD-L1 with PD-1 receptors, BAVENCIO has been shown to release the suppression of the T cell-mediated antitumor immune response in preclinical models.15-17 BAVENCIO has also been shown to induce NK cell-mediated direct tumor cell lysis via antibody-dependent cell-mediated cytotoxicity (ADCC) in vitro.17-19 In November 2014, Merck KGaA, Darmstadt, Germany, and Pfizer announced a strategic alliance to co-develop and co-commercialize BAVENCIO.

BAVENCIO Important Safety Information from the US FDA-Approved Label

BAVENCIO can cause immune-mediated pneumonitis, including fatal cases. Monitor patients for signs and symptoms of pneumonitis, and evaluate suspected cases with radiographic imaging. Administer corticosteroids for Grade 2 or greater pneumonitis. Withhold BAVENCIO for moderate (Grade 2) and permanently discontinue for severe (Grade 3), life-threatening (Grade 4), or recurrent moderate (Grade 2) pneumonitis. Pneumonitis occurred in 1.2% of patients, including one (0.1%) patient with Grade 5, one (0.1%) with Grade 4, and five (0.3%) with Grade 3.

BAVENCIO can cause hepatotoxicity and immune-mediated hepatitis, including fatal cases. Monitor patients for abnormal liver tests prior to and periodically during treatment. Administer corticosteroids for Grade 2 or greater hepatitis. Withhold BAVENCIO for moderate (Grade 2) immune-mediated hepatitis until resolution and permanently discontinue for severe (Grade 3) or life-threatening (Grade 4) immune-mediated hepatitis. Immune-mediated hepatitis occurred with BAVENCIO as a single agent in 0.9% of patients, including two (0.1%) patients with Grade 5, and 11 (0.6%) with Grade 3.

BAVENCIO in combination with INLYTA can cause hepatotoxicity with higher than expected frequencies of Grade 3 and 4 alanine aminotransferase (ALT) and aspartate aminotransferase (AST) elevation. Consider more frequent monitoring of liver enzymes as compared to when the drugs are used as monotherapy. Withhold BAVENCIO and INLYTA for moderate (Grade 2) hepatotoxicity and permanently discontinue the combination for severe or life-threatening (Grade 3 or 4) hepatotoxicity. Administer corticosteroids as needed. In patients treated with BAVENCIO in combination with INLYTA, Grades 3 and 4 increased ALT and AST occurred in 9% and 7% of patients, respectively, and immune-mediated hepatitis occurred in 7% of patients, including 4.9% with Grade 3 or 4.

BAVENCIO can cause immune-mediated colitis. Monitor patients for signs and symptoms of colitis. Administer corticosteroids for Grade 2 or greater colitis. Withhold BAVENCIO until resolution for moderate or severe (Grade 2 or 3) colitis until resolution. Permanently discontinue for life-threatening (Grade 4) or recurrent (Grade 3) colitis upon reinitiation of BAVENCIO. Immune-mediated colitis occurred in 1.5% of patients, including seven (0.4%) with Grade 3.

BAVENCIO can cause immune-mediated endocrinopathies, including adrenal insufficiency, thyroid disorders, and type 1 diabetes mellitus.

Monitor patients for signs and symptoms of adrenal insufficiency during and after treatment, and administer corticosteroids as appropriate. Withhold BAVENCIO for severe (Grade 3) or life-threatening (Grade 4) adrenal insufficiency. Adrenal insufficiency was reported in 0.5% of patients, including one (0.1%) with Grade 3.

Thyroid disorders can occur at any time during treatment. Monitor patients for changes in thyroid function at the start of treatment, periodically during treatment, and as indicated based on clinical evaluation. Manage hypothyroidism with hormone replacement therapy and hyperthyroidism with medical management. Withhold BAVENCIO for severe (Grade 3) or life-threatening (Grade 4) thyroid disorders. Thyroid disorders, including hypothyroidism, hyperthyroidism, and thyroiditis, were reported in 6% of patients, including three (0.2%) with Grade 3.

Type 1 diabetes mellitus including diabetic ketoacidosis: Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Withhold BAVENCIO and administer antihyperglycemics or insulin in patients with severe or life-threatening (Grade ≥3) hyperglycemia, and resume treatment when metabolic control is achieved. Type 1 diabetes mellitus without an alternative etiology occurred in 0.1% of patients, including two cases of Grade 3 hyperglycemia.

BAVENCIO can cause immune-mediated nephritis and renal dysfunction. Monitor patients for elevated serum creatinine prior to and periodically during treatment. Administer corticosteroids for Grade 2 or greater nephritis. Withhold BAVENCIO for moderate (Grade 2) or severe (Grade 3) nephritis until resolution to Grade 1 or lower. Permanently discontinue BAVENCIO for life-threatening (Grade 4) nephritis. Immune-mediated nephritis occurred in 0.1% of patients.

BAVENCIO can result in other severe and fatal immune-mediated adverse reactions involving any organ system during treatment or after treatment discontinuation. For suspected immune-mediated adverse reactions, evaluate to confirm or rule out an immune-mediated adverse reaction and to exclude other causes. Depending on the severity of the adverse reaction, withhold or permanently discontinue BAVENCIO, administer high-dose corticosteroids, and initiate hormone replacement therapy, if appropriate. Resume BAVENCIO when the immune-mediated adverse reaction remains at Grade 1 or lower following a corticosteroid taper. Permanently discontinue BAVENCIO for any severe (Grade 3) immune-mediated adverse reaction that recurs and for any life-threatening (Grade 4) immune-mediated adverse reaction. The following clinically significant immune-mediated adverse reactions occurred in less than 1% of 1738 patients treated with BAVENCIO as a single agent or in 489 patients who received BAVENCIO in combination with INLYTA: myocarditis including fatal cases, pancreatitis including fatal cases, myositis, psoriasis, arthritis, exfoliative dermatitis, erythema multiforme, pemphigoid, hypopituitarism, uveitis, Guillain-Barré syndrome, and systemic inflammatory response.

BAVENCIO can cause severe or life-threatening infusion-related reactions. Premedicate patients with an antihistamine and acetaminophen prior to the first 4 infusions and for subsequent infusions based upon clinical judgment and presence/severity of prior infusion reactions. Monitor patients for signs and symptoms of infusion-related reactions, including pyrexia, chills, flushing, hypotension, dyspnea, wheezing, back pain, abdominal pain, and urticaria. Interrupt or slow the rate of infusion for mild (Grade 1) or moderate (Grade 2) infusion-related reactions. Permanently discontinue BAVENCIO for severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Infusion-related reactions occurred in 25% of patients, including three (0.2%) patients with Grade 4 and nine (0.5%) with Grade 3.

BAVENCIO in combination with INLYTA can cause major adverse cardiovascular events (MACE) including severe and fatal events. Consider baseline and periodic evaluations of left ventricular ejection fraction. Monitor for signs and symptoms of cardiovascular events. Optimize management of cardiovascular risk factors, such as hypertension, diabetes, or dyslipidemia. Discontinue BAVENCIO and INLYTA for Grade 3-4 cardiovascular events. MACEoccurred in 7% of patients with advanced RCC treated with BAVENCIO in combination with INLYTA compared to 3.4% treated with sunitinib. These events included death due to cardiac events (1.4%), Grade 3-4 myocardial infarction (2.8%), and Grade 3-4 congestive heart failure (1.8%).

BAVENCIO can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risk to a fetus including the risk of fetal death. Advise females of childbearing potential to use effective contraception during treatment with BAVENCIO and for at least 1 month after the last dose of BAVENCIO. It is not known whether BAVENCIO is excreted in human milk. Advise a lactating woman not to breastfeed during treatment and for at least 1 month after the last dose of BAVENCIO due to the potential for serious adverse reactions in breastfed infants.
