This year, ASCO (Free ASCO Whitepaper) will be highlighting—during its embargoed presscast on Tuesday, May 26 and at the plenary session on Sunday, May 31—the Phase III JAVELIN Bladder 100 study (Abstract# LBA1) of BAVENCIO (avelumab) in the first-line maintenance treatment of patients with locally advanced or metastatic urothelial carcinoma (UC)*. Additional data will be presented for early- to late-stage molecules discovered and developed in-house that demonstrate the Company’s commitment and relentless drive to discover, develop and deliver innovative treatment options in its hope to turn cancer patients into cancer survivors. Research from several investigator-sponsored and collaborative research studies also will be shared. This includes a late-breaking oral presentation of results of the investigator-sponsored, multicenter Phase II TROPHIMMUN study of avelumab for the treatment of chemotherapy-resistant gestational trophoblastic tumors (Cohort A), which also will be featured in the ASCO (Free ASCO Whitepaper) press program (Abstract# LBA6008).

"Despite the many advances in cancer treatment, we have an urgency to continue to discover and develop innovative treatment options that will have a major impact on the lives of people living with cancer," said Luciano Rossetti, Global Head of Research & Development for EMD Serono. "Taking on this challenge, we’ve applied our deep knowledge of cancer biology to highly focused areas to develop the first-in-class oral MET inhibitor, tepotinib, which received the first approval anywhere in the world for the treatment of NSCLC with MET gene alterations, and our first-in-class bifunctional fusion protein immunotherapy, bintrafusp alfa, both of which have promising outcomes featured at this year’s ASCO (Free ASCO Whitepaper) meeting."

For tepotinib†, approved in Japan for the treatment of patients with unresectable, advanced or recurrent non-small cell lung cancer (NSCLC) with MET exon 14 (METex14) skipping alterations and the first oral MET inhibitor indicated for the treatment of advanced NSCLC harboring MET gene alterations to receive a regulatory approval, data will be presented from the primary analysis of the VISION study with promising activity in patients with advanced EGFR/ALK wild-type, METex14 skipping NSCLC who were prospectively enrolled using liquid biopsy or tissue biopsy. Results (Abstract #9556) include ≥6-month follow-up data for the primary endpoint of objective response rate (ORR) as determined by independent review committee. Secondary endpoints include ORR as assessed by investigators, duration of response, disease control rate, progression-free survival, molecular responses, and safety data. Additionally, patient-reported outcomes (PROs) of health-related quality of life (HRQoL) for the VISION study will be presented at the meeting (Abstract# 9575). These outcomes are the first time HRQoL have been reported for patients with METex14 skipping NSCLC.

For bintrafusp alfa, a novel bifunctional fusion protein targeting TGF-β and PD-L1, two-year follow-up data from a global Phase I study in second-line NSCLC will be presented (Abstract# 9558). These data continue to show manageable safety with durable responses and encouraging long-term survival, especially in patients with high PD-L1 expression (≥80%). The overall safety profile has remained consistent since the interim analysis, with no new safety signals or deaths and one additional treatment-related discontinuation (blood alkaline phosphatase increased). Studies in the bintrafusp alfa lung cancer program include:

INTR@PID LUNG 037: Adaptive Phase III, randomized, open-label controlled study of bintrafusp alfa compared with pembrolizumab as a first-line treatment in patients with PD-L1 expressing advanced NSCLC;
INTR@PID LUNG 005: Phase II study of bintrafusp alfa with concurrent chemoradiation therapy (cCRT) in unresectable Stage III NSCLC; and
INTR@PID LUNG 024: Phase Ib/II, open-label study of bintrafusp alfa in combination with chemotherapy in participants with Stage IV NSCLC regardless of PD-L1 expression status.
The Company’s broad portfolio of investigational DNA damage response (DDR) inhibitors represents multiple development paths, including combinations with other agents and modalities. A trial-in-progress poster (Abstract #TPS4117) will review a multicenter Phase Ib/II study evaluating the safety, tolerability, pharmacokinetics and efficacy of the DNA-PK inhibitor peposertib (formerly M3814) in combination with capecitabine and radiotherapy as neoadjuvant treatment in patients with locally advanced rectal cancer.

*BAVENCIO is under clinical investigation for the first-line maintenance treatment of advanced UC. There is no guarantee that BAVENCIO will be approved for first-line maintenance treatment of advanced UC by any health authority worldwide.

†Tepotinib is currently under clinical investigation in NSCLC and not yet approved in any markets outside of Japan.

‡Bintrafusp alfa is currently under clinical investigation and not approved for any use anywhere in the world.

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.10-12 In November 2014, Merck KGaA, Darmstadt, Germany and Pfizer announced a strategic alliance to co-develop and co-commercialize BAVENCIO.

BAVENCIO Approved Indications

BAVENCIO (avelumab) in combination with axitinib is indicated in the US for the first-line treatment of patients with advanced renal cell carcinoma (RCC).

In the US, the FDA granted accelerated approval for BAVENCIO for the treatment of (i) adults and pediatric patients 12 years and older with metastatic Merkel cell carcinoma (mMCC) and (ii) patients with locally advanced or metastatic urothelial carcinoma (mUC) who have disease progression during or following platinum-containing chemotherapy, or have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. These indications are approved under accelerated approval based on tumor response rate and duration of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.

Avelumab is currently approved for patients with MCC in 50 countries globally, with the majority of these approvals in a broad indication that is not limited to a specific line of treatment.

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 axitinib 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 axitinib 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 axitinib, 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 axitinib: 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 axitinib 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 axitinib for Grade 3-4 cardiovascular events. MACE occurred in 7% of patients with advanced RCC treated with BAVENCIO in combination with axitinib 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.

About tepotinib

Tepotinib is an oral MET inhibitor that is designed to inhibit the oncogenic MET receptor signaling caused by MET (gene) alterations, including both METex14 skipping alterations and MET amplifications, or MET protein overexpression. Discovered in-house at Merck KGaA, Darmstadt, Germany, it has been designed to have a highly selective mechanism of action,7 with the potential to improve outcomes in aggressive tumors that have a poor prognosis and harbor these specific alterations. Tepotinib is currently under clinical investigation in NSCLC and not yet approved in any markets outside of Japan. Merck KGaA, Darmstadt, Germany is actively assessing the potential of investigating tepotinib in combination with novel therapies and in other tumor indications. Tepotinib is approved under the brand name TEPMETKO in Japan for the treatment of unresectable, advanced or recurrent non-small cell lung cancer (NSCLC) with MET exon 14 (METex14) skipping alterations. The brand name TEPMETKO is not approved for use outside of Japan.

About bintrafusp alfa

Bintrafusp alfa (M7824), discovered in-house at Merck KGaA, Darmstadt, Germany, is a potential first-in-class investigational bifunctional fusion protein designed to simultaneously block two immunosuppressive pathways, TGF-β and PD-L1, within the tumor microenvironment. This bifunctional approach is thought to control tumor growth by potentially restoring and enhancing anti-tumor responses. In preclinical studies, bintrafusp alfa has demonstrated antitumor activity both as monotherapy and in combination with chemotherapy. Based on its mechanism of action, bintrafusp alfa offers a potential targeted approach to addressing the underlying pathophysiology of difficult-to-treat cancers.

INTR@PID is the global clinical trial program investigating the potential co-localized, dual inhibition of TGF-β and PD-L1 with bintrafusp alfa (M7824) in multiple tumor types. Current clinical trial information can be found on the INTR@PID website at www.intrapidclinicaltrials.com. To date, more than 850 patients with various types of solid tumors have been treated globally in the bintrafusp alfa INTR@PID clinical development program.

Important Safety Information

Warnings and Precautions

Hypertension. In DTC, hypertension occurred in 73% of patients on LENVIMA (44% grade 3-4). In RCC, hypertension occurred in 42% of patients on LENVIMA + everolimus (13% grade 3). Systolic blood pressure ≥160 mmHg occurred in 29% of patients, and 21% had diastolic blood pressure ≥100 mmHg. In HCC, hypertension occurred in 45% of LENVIMA-treated patients (24% grade 3). Grade 4 hypertension was not reported in HCC.

Serious complications of poorly controlled hypertension have been reported. Control blood pressure prior to initiation. Monitor blood pressure after 1 week, then every 2 weeks for the first 2 months, and then at least monthly thereafter during treatment. Withhold and resume at reduced dose when hypertension is controlled or permanently discontinue based on severity.

Cardiac Dysfunction. Serious and fatal cardiac dysfunction can occur with LENVIMA. Across clinical trials in 799 patients with DTC, RCC, and HCC, grade 3 or higher cardiac dysfunction occurred in 3% of LENVIMA treated patients. Monitor for clinical symptoms or signs of cardiac dysfunction. Withhold and resume at reduced dose upon recovery or permanently discontinue based on severity

Arterial Thromboembolic Events. Among patients receiving LENVIMA or LENVIMA + everolimus, arterial thromboembolic events of any severity occurred in 2% of patients in RCC and HCC and 5% in DTC. Grade 3-5 arterial thromboembolic events ranged from 2% to 3% across all clinical trials. Permanently discontinue following an arterial thrombotic event. The safety of resuming after an arterial thromboembolic event has not been established and LENVIMA has not been studied in patients who have had an arterial thromboembolic event within the previous 6 months.

Hepatotoxicity. Across clinical studies enrolling 1,327 LENVIMA-treated patients with malignancies other than HCC, serious hepatic adverse reactions occurred in 1.4% of patients. Fatal events, including hepatic failure, acute hepatitis and hepatorenal syndrome, occurred in 0.5% of patients. In HCC, hepatic encephalopathy occurred in 8% of LENVIMA-treated patients (5% grade 3-5). Grade 3-5 hepatic failure occurred in 3% of LENVIMA-treated patients. 2% of patients discontinued LENVIMA due to hepatic encephalopathy and 1% discontinued due to hepatic failure.

Monitor liver function prior to initiation, then every 2 weeks for the first 2 months, and at least monthly thereafter during treatment. Monitor patients with HCC closely for signs of hepatic failure, including hepatic encephalopathy. Withhold and resume at reduced dose upon recovery or permanently discontinue based on severity.

Renal Failure or Impairment. Serious including fatal renal failure or impairment can occur with LENVIMA. Renal impairment was reported in 14% and 7% of LENVIMA-treated patients in DTC and HCC, respectively. Grade 3-5 renal failure or impairment occurred in 3% of patients with DTC and 2% of patients with HCC, including 1 fatal event in each study. In RCC, renal impairment or renal failure was reported in 18% of LENVIMA + everolimus–treated patients (10% grade 3).

Initiate prompt management of diarrhea or dehydration/hypovolemia. Withhold and resume at reduced dose upon recovery or permanently discontinue for renal failure or impairment based on severity.

Proteinuria. In DTC and HCC, proteinuria was reported in 34% and 26% of LENVIMA-treated patients, respectively. Grade 3 proteinuria occurred in 11% and 6% in DTC and HCC, respectively. In RCC, proteinuria occurred in 31% of patients receiving LENVIMA + everolimus (8% grade 3). Monitor for proteinuria prior to initiation and periodically during treatment. If urine dipstick proteinuria ≥2+ is detected, obtain a 24-hour urine protein. Withhold and resume at reduced dose upon recovery or permanently discontinue based on severity.

Diarrhea. Of the 737 LENVIMA-treated patients in DTC and HCC, diarrhea occurred in 49% (6% grade 3). In RCC, diarrhea occurred in 81% of LENVIMA + everolimus–treated patients (19% grade 3). Diarrhea was the most frequent cause of dose interruption/reduction, and diarrhea recurred despite dose reduction. Promptly initiate management of diarrhea. Withhold and resume at reduced dose upon recovery or permanently discontinue based on severity.

Fistula Formation and Gastrointestinal Perforation. Of the 799 patients treated with LENVIMA or LENVIMA + everolimus in DTC, RCC, and HCC, fistula or gastrointestinal perforation occurred in 2%. Permanently discontinue in patients who develop gastrointestinal perforation of any severity or grade 3-4 fistula.

QT Interval Prolongation. In DTC, QT/QTc interval prolongation occurred in 9% of LENVIMA-treated patients and QT interval prolongation of >500 ms occurred in 2%. In RCC, QTc interval increases of >60 ms occurred in 11% of patients receiving LENVIMA + everolimus and QTc interval >500 ms occurred in 6%. In HCC, QTc interval increases of >60 ms occurred in 8% of LENVIMA-treated patients and QTc interval >500 ms occurred in 2%.

Monitor and correct electrolyte abnormalities at baseline and periodically during treatment. Monitor electrocardiograms in patients with congenital long QT syndrome, congestive heart failure, bradyarrhythmias, or those who are taking drugs known to prolong the QT interval, including Class Ia and III antiarrhythmics. Withhold and resume at reduced dose upon recovery based on severity.

Hypocalcemia. In DTC, grade 3-4 hypocalcemia occurred in 9% of LENVIMA-treated patients. In 65% of cases, hypocalcemia improved or resolved following calcium supplementation with or without dose interruption or dose reduction. In RCC, grade 3-4 hypocalcemia occurred in 6% of LENVIMA + everolimus– treated patients. In HCC, grade 3 hypocalcemia occurred in 0.8% of LENVIMA-treated patients. Monitor blood calcium levels at least monthly and replace calcium as necessary during treatment. Withhold and resume at reduced dose upon recovery or permanently discontinue depending on severity.

Reversible Posterior Leukoencephalopathy Syndrome. Across clinical studies of 1,823 patients who received LENVIMA as a single agent, RPLS occurred in 0.3%. Confirm diagnosis of RPLS with MRI. Withhold and resume at reduced dose upon recovery or permanently discontinue depending on severity and persistence of neurologic symptoms.

Hemorrhagic Events. Serious including fatal hemorrhagic events can occur with LENVIMA. In DTC, RCC, and HCC clinical trials, hemorrhagic events, of any grade, occurred in 29% of the 799 patients treated with LENVIMA as a single agent or in combination with everolimus. The most frequently reported hemorrhagic events (all grades and occurring in at least 5% of patients) were epistaxis and hematuria. In DTC, grade 3-5 hemorrhage occurred in 2% of LENVIMA-treated patients, including 1 fatal intracranial hemorrhage among 16 patients who received LENVIMA and had CNS metastases at baseline. In RCC, grade 3-5 hemorrhage occurred in 8% of LENVIMA + everolimus–treated patients, including 1 fatal cerebral hemorrhage. In HCC, grade 3-5 hemorrhage occurred in 5% of LENVIMA-treated patients, including 7 fatal hemorrhagic events. Serious tumor-related bleeds, including fatal hemorrhagic events, occurred in LENVIMA-treated patients in clinical trials and in the postmarketing setting. In postmarketing surveillance, serious and fatal carotid artery hemorrhages were seen more frequently in patients with anaplastic thyroid carcinoma (ATC) than other tumors. Safety and effectiveness of LENVIMA in patients with ATC have not been demonstrated in clinical trials.

Consider the risk of severe or fatal hemorrhage associated with tumor invasion or infiltration of major blood vessels (eg, carotid artery). Withhold and resume at reduced dose upon recovery or permanently discontinue based on severity.

Impairment of Thyroid Stimulating Hormone Suppression/Thyroid Dysfunction. LENVIMA impairs exogenous thyroid suppression. In DTC, 88% of patients had baseline thyroid stimulating hormone (TSH) level ≤0.5 mU/L. In patients with normal TSH at baseline, elevation of TSH level >0.5 mU/L was observed post baseline in 57% of LENVIMA-treated patients. In RCC and HCC, grade 1 or 2 hypothyroidism occurred in 24% of LENVIMA + everolimus–treated patients and 21% of LENVIMA-treated patients, respectively. In patients with normal or low TSH at baseline, elevation of TSH was observed post baseline in 70% of LENVIMA-treated patients in HCC and 60% of LENVIMA + everolimus–treated patients in RCC.

Monitor thyroid function prior to initiation and at least monthly during treatment. Treat hypothyroidism according to standard medical practice.

Impaired Wound Healing. Impaired wound healing has been reported in patients who received LENVIMA. Withhold LENVIMA for at least 1 week prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing. The safety of resumption of LENVIMA after resolution of wound healing complications has not been established.

Embryo-fetal Toxicity. Based on its mechanism of action and data from animal reproduction studies, LENVIMA can cause fetal harm when administered to pregnant women. In animal reproduction studies, oral administration of lenvatinib during organogenesis at doses below the recommended clinical doses resulted in embryotoxicity, fetotoxicity, and teratogenicity in rats and rabbits. Advise pregnant women of the potential risk to a fetus; and advise females of reproductive potential to use effective contraception during treatment with LENVIMA and for at least 30 days after the last dose.

About HALAVEN (eribulin mesylate) Injection

HALAVEN (eribulin mesylate) is a microtubule dynamics inhibitor indicated for the treatment of patients with:

Metastatic breast cancer who have previously received at least two chemotherapeutic regimens for the treatment of metastatic disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting.
Unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen.
Discovered and developed by Eisai, eribulin is a synthetic analog of halichondrin B, a natural product that was isolated from the marine sponge Halichondria okadai. First in the halichondrin class, eribulin is a microtubule dynamics inhibitor. Eribulin is believed to work primarily via a tubulin-based mechanism that causes prolonged and irreversible mitotic blockage, ultimately leading to apoptotic cell death. Additionally, in preclinical studies of human breast cancer, eribulin demonstrated complex effects on the tumor biology of surviving cancer cells, including increases in vascular perfusion resulting in reduced tumor hypoxia, and changes in the expression of genes in tumor specimens associated with a change in phenotype, promoting the epithelial phenotype, opposing the mesenchymal phenotype. Eribulin has also been shown to decrease the migration and invasiveness of human breast cancer cells.

Important Safety Information

Warnings and Precautions

Neutropenia: Severe neutropenia (ANC <500/mm3) lasting >1 week occurred in 12% of patients with mBC and liposarcoma or leiomyosarcoma. Febrile neutropenia occurred in 5% of patients with mBC and 2 patients (0.4%) died from complications. Febrile neutropenia occurred in 0.9% of patients with liposarcoma or leiomyosarcoma, and fatal neutropenic sepsis occurred in 0.9% of patients. Patients with mBC with elevated liver enzymes >3 × ULN and bilirubin >1.5 × ULN experienced a higher incidence of Grade 4 neutropenia and febrile neutropenia than patients with normal levels. Monitor complete blood cell counts prior to each dose, and increase the frequency of monitoring in patients who develop Grade 3 or 4 cytopenias. Delay administration and reduce subsequent doses in patients who experience febrile neutropenia or Grade 4 neutropenia lasting >7 days.

Peripheral Neuropathy: Grade 3 peripheral neuropathy occurred in 8% of patients with mBC (Grade 4=0.4%) and 22% developed a new or worsening neuropathy that had not recovered within a median follow-up duration of 269 days (range 25-662 days). Neuropathy lasting >1 year occurred in 5% of patients with mBC. Grade 3 peripheral neuropathy occurred in 3.1% of patients with liposarcoma and leiomyosarcoma receiving HALAVEN and neuropathy lasting more than 60 days occurred in 58% (38/65) of patients who had neuropathy at the last treatment visit. Patients should be monitored for signs of peripheral motor and sensory neuropathy. Withhold HALAVEN in patients who experience Grade 3 or 4 peripheral neuropathy until resolution to Grade 2 or less.

Embryo-Fetal Toxicity: HALAVEN can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during treatment with HALAVEN and for at least 2 weeks following the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with HALAVEN and for 3.5 months following the final dose.

QT Prolongation: Monitor for prolonged QT intervals in patients with congestive heart failure, bradyarrhythmias, drugs known to prolong the QT interval, and electrolyte abnormalities. Correct hypokalemia or hypomagnesemia prior to initiating HALAVEN and monitor these electrolytes periodically during therapy. Avoid in patients with congenital long QT syndrome.

Adverse Reactions
In patients with mBC receiving HALAVEN, the most common adverse reactions (≥25%) were neutropenia (82%), anemia (58%), asthenia/fatigue (54%), alopecia (45%), peripheral neuropathy (35%), nausea (35%), and constipation (25%). Febrile neutropenia (4%) and neutropenia (2%) were the most common serious adverse reactions. The most common adverse reaction resulting in discontinuation was peripheral neuropathy (5%).

In patients with liposarcoma and leiomyosarcoma receiving HALAVEN, the most common adverse reactions (≥25%) reported in patients receiving HALAVEN were fatigue (62%), nausea (41%), alopecia (35%), constipation (32%), peripheral neuropathy (29%), abdominal pain (29%), and pyrexia (28%). The most common (≥5%) Grade 3-4 laboratory abnormalities reported in patients receiving HALAVEN were neutropenia (32%), hypokalemia (5.4%), and hypocalcemia (5%). Neutropenia (4.9%) and pyrexia (4.5%) were the most common serious adverse reactions. The most common adverse reactions resulting in discontinuation were fatigue and thrombocytopenia (0.9% each).

Use in Specific Populations

About ecDNA

Extrachromosomal DNA, or ecDNA, are large circles of DNA containing genes that are outside the cells’ chromosomes and can make many copies of themselves. ecDNA can be rapidly replicated within the cell, causing high numbers of oncogene copies, a trait that can be passed to daughter cells in asymmetric ways during cell division. Cells have the ability to upregulate or downregulate ecDNA and resulting oncogenes to ensure survival under selective pressures, including chemotherapy, targeted therapy, immunotherapy, or radiation, making ecDNA one of cancer cells’ primary mechanisms of recurrence and treatment evasion. ecDNA are rarely seen in healthy cells but are found in many solid tumor cancers. They are a key driver of the most aggressive and difficult-to-treat cancers, specifically those characterized by high copy number amplification of oncogenes.

Updated Results from Phase 1b/2 Study of BCMA CAR-T Therapy JNJ-4528 Shows Early, Deep and Durable Responses in Heavily Pretreated Patients with Relapsed or Refractory Multiple Myeloma

On May 13, 2020 Legend Biotech Corporation ("Legend") reported updated results from the Janssen Pharmaceutical Companies of Johnson & Johnson ("Janssen") sponsored Phase 1b/2 CARTITUDE-1 study (NCT03548207)1 evaluating the efficacy and safety of JNJ-68284528 (JNJ-4528), an investigational B-cell maturation antigen (BCMA)-directed chimeric antigen receptor T cell (CAR-T) therapy in the treatment of patients with relapsed or refractory multiple myeloma (Press release, Legend Biotech, MAY 13, 2020, View Source [SID1234557942]). JNJ-4528 is a structurally differentiated CAR-T cell therapy containing a 4-1BB co-stimulatory domain and two BCMA-targeting single-domain antibodies designed to confer avidity.2

Longer-term follow-up results from the Phase 1b portion of the study (n=29), to be shared in an oral presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Virtual Scientific Program (Abstract #8505), show that all patients responded to treatment and that the responses were deep and durable with 86 percent of patients achieving stringent complete response at a median follow-up time of 11.5 months. In addition, results showed a 100 percent overall response rate (ORR), which included 97 percent of patients achieving a very good partial response or better and three percent achieving a partial response. The median time to first response was one month (range, 1-3), and 81 percent of evaluable patients (n=16) achieved minimal residual disease (MRD)-negative disease status at 10-5 or 10-6 at the time of first suspected complete response. The 9-month progression free survival rate was 86 percent and 22 of 29 patients remained alive and progression free at the time of data cut-off. Patients in the study were heavily pre-treated and received a median dose of 0.72×106 CAR+ viable T cells/kg.3

Patients evaluated received a median of five (range, 3-18) prior treatment regimens; 86 percent were triple-refractory and 28 percent were penta-refractory.

"The longer-term results for JNJ-4528, as demonstrated through the latest findings from the CARTITUDE-1 study, show the continued treatment effect for heavily pre-treated patients who faced a poor prognosis," said Jesus G. Berdeja, M.D., Director of Myeloma Research, Sarah Cannon Research Institute, and principal study investigator. "We’re encouraged by not only the relatively high rate of stringent complete responses, but the strong progression-free survival results seen in these patients."

The most common adverse events (AEs) observed in CARTITUDE-1 were neutropenia (100 percent) and cytokine release syndrome (CRS) (93 percent). The median time to onset of CRS was seven days (range, 2-12) post-infusion, with a majority of patients experiencing Grade 1-2 CRS and two patients experiencing Grade 3 or greater CRS. In patients who experienced Grade 3 and above AEs, the most common were neutropenia (100 percent), thrombocytopenia (69 percent), and leukopenia (66 percent). Neurotoxicity consistent with ICANS was observed in 3 patients (10 percent) including 1 patient (3 percent) with ≥ Grade 3 toxicity. There were 3 deaths during the Phase 1b study: one due to CRS, one due to acute myeloid leukemia (not treatment-related), and one due to progressive disease.3

"We are heartened by the follow-up data from the Phase 1b portion of the CARTITUDE-1 study as they further support the findings from the LEGEND-2 study in China, with both demonstrating deep, durable treatment responses," said Yuan Xu, PhD, Chief Executive Officer and Board Member of Legend Biotech. "We remain committed to work closely with our strategic partner and key stakeholders to advance JNJ-4528 through clinical development, in line with our mission to deliver innovative cell therapy options to patients living with cancer."

About CARTITUDE-1

CARTITUDE-1 (NCT03548207) is an ongoing Phase 1b/2, open-label, multicenter study evaluating the safety and efficacy of JNJ-4528 in adults with relapsed or refractory multiple myeloma. Of the patients in the Phase 1b portion (n=29), 97 percent were refractory to last line of treatment and 86 percent were triple-class refractory, meaning their cancer did not respond to an immunomodulatory agent (IMiD), a proteasome inhibitor (PI) and an anti-CD38 antibody.

The primary objective of the Phase 1b portion of the study was to characterize the safety and confirm the dose of JNJ-4528, informed by the first-in-human study with LCAR-B38M CAR-T cells (LEGEND-2). Based on the safety profile observed in this portion of the study, outpatient dosing will be evaluated in additional CARTITUDE studies. The Phase 2 portion of the study will evaluate the efficacy of JNJ-4528 with overall response as the primary endpoint.

About JNJ-4528 (LCAR-B38M)

JNJ-4528 (LCAR-B38M) is an investigational CAR-T therapy for the treatment of patients with RRMM. The design comprises a structurally differentiated CAR-T with two BCMA-targeting single domain antibodies.

JNJ-4528 identifies the investigational product being studied in the US, Europe, and Japan. LCAR-B38M identifies the investigational product being studied in China. Both represent the same CAR-T cell therapy.

In December 2017, Legend Biotech, USA Inc., and Legend Biotech Ireland Limited, entered into a worldwide collaboration and license agreement with Janssen, to jointly develop and commercialize JNJ-4528/LCAR-B38M in multiple myeloma.

In May 20184, Legend announced that the U.S. Food and Drug Administration (FDA) authorized Janssen to initiate a Phase 1b/2 trial (NCT03548207)1 to evaluate the efficacy and safety of JNJ-4528 in adults with RRMM, informed by the LEGEND-2 (NCT03090659)5 study results.

In December 20196, Legend announced that the FDA granted Janssen Breakthrough Therapy Designation, which is granted to expedite the development and regulatory review of an investigational medicine that is intended to treat a serious or life-threatening condition.7 In February 20198, the U.S. FDA granted Janssen an Orphan Drug Designation for JNJ-4528. In April 20199, JNJ-4528 was granted PRIME (PRIority MEdicines) designation by the European Medicines Agency (EMA). PRIME offers enhanced interaction and early dialogue to optimize development plans and speed up evaluation of cutting-edge, scientific advances that target a high unmet medical need.10 In February 2020, the European Commission granted Janssen an Orphan Drug Designation for JNJ-4528.11

About Multiple Myeloma

Multiple myeloma is currently an incurable blood cancer that starts in the bone marrow and is characterized by an excessive proliferation of plasma cells.12 Although treatment may result in remission, patients will most likely relapse as there is currently no cure.13 Refractory multiple myeloma is when a patient’s disease is nonresponsive or progresses within 60 days of their last therapy.14,15 Relapsed myeloma is when the disease has returned after a period of initial, partial or complete remission and does not meet the definition of being refractory.16 While some patients with multiple myeloma have no symptoms at all, most patients are diagnosed due to symptoms that can include bone problems, low blood counts, calcium elevation, kidney problems or infections.17 Patients who relapse after treatment with standard therapies, including protease inhibitors and immunomodulatory agents, have poor prognoses and few treatment options available.18
