cambridge, mass. and tokyo, july 8,2021(globe newswire) – biogen (nasdaq: biib) and eisai co., ltd. (tokyo, japan) today announced the u.s. food and drug administration (fda) has approved an updated label for aduhelm™ (aducanumab-avwa) injection 100 mg/ml solution.

the update includes an addition to the indications and usage section of the label (section 1) to emphasize the disease stages studied in the clinical trials, as seen below (italics to note updated language).

aduhelm is indicated for the treatment of alzheimer’s disease. treatment with aduhelm should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials.there are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied. this indication is approved under accelerated approval based on reduction in amyloid beta plaques observed in patients treated with aduhelm. continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trial(s).

alfred sandrock, jr., m.d., ph.d., head of research and development at biogen, said, “based on our ongoing conversations with prescribing physicians, fda and patient advocates, we submitted this label update with the goal to further clarify the patient population that was studied across the three aduhelm clinical trials that supported approval. we are committed to continue to listen to the community’s needs as clinical practice adapts to this important, first-in-class treatment option.”

the update clarifies the indication by emphasizing information about the disease stages studied in the aduhelm clinical trials. information about the population studied has been previously communicated by biogen and eisai, including in the companies’statement of june 23, 2021.

applications based on progression-free survival, overall survival, and objective response rate data from respective pivotal phase 3 trials

 

tokyo and kenilworth, n.j., may 6, 2021 – eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) and merck & co., inc., kenilworth, n.j., u.s.a. (known as msd outside the united states and canada) today announced that the u.s. food and drug administration (fda) has accepted and granted priority review for applications seeking two new approvals for the combination of lenvima, the orally available multiple receptor tyrosine kinase inhibitor discovered by eisai, plus keytruda, the anti-pd-1 therapy from merck & co., inc., kenilworth, n.j., u.s.a. the first set of applications (a supplemental new drug application [snda] for lenvima and a supplemental biologics license application [sbla] for keytruda) are for the first-line treatment of patients with advanced renal cell carcinoma (rcc), based on progression-free survival (pfs), overall survival (os) and objective response rate (orr) data from the pivotal phase 3 clear study (study 307/keynote-581). the second set of applications are for the treatment of patients with advanced endometrial carcinoma who have disease progression following prior systemic therapy in any setting and are not candidates for curative surgery or radiation, based on pfs, os, and orr data from the pivotal phase 3 study 309/keynote-775 trial. these are the first applications to be submitted in the u.s. for this combination therapy based on phase 3 clinical data. the fda has set prescription drug user fee act (pdufa) dates, or target action dates, of august 25 and 26, 2021, for the advanced rcc snda and sbla applications, respectively, and september 3, 2021, for the advanced endometrial carcinoma applications.

“advanced renal cell carcinoma and advanced endometrial carcinoma are aggressive cancers, and patients urgently need new treatment options that may help improve outcomes,” said dr. gregory lubiniecki, vice president, oncology clinical research, merck & co., inc., kenilworth, n.j., u.s.a. research laboratories. “we appreciate that the fda has recognized this significant unmet need and the potential for the combination of keytruda plus lenvima in these patients by granting priority review for these applications.”

“we are pleased that the fda has granted priority review for lenvima plus keytruda—both in advanced renal cell carcinoma and advanced endometrial carcinoma— underscoring the potential significance of the outcomes observed in the clear study (study 307/keynote-581) and study 309/keynote-775 trials,” said dr. takashi owa, chief medicine creation officer and chief discovery officer, oncology business group at eisai. “many patients are still in need of new and effective therapies, which fuels our commitment to advancing the development of this combination even more. these milestones reinforce our unwavering dedication to helping the patients we aim to serve.”

the applications in advanced rcc are based on results from the clear study (study 307/keynote-581), in which lenvima plus keytruda demonstrated statistically significant improvements in pfs, os and orr versus sunitinib. these data were presented in february at the virtual 2021 genitourinary cancers symposium (asco gu) and simultaneously published in the new england journal of medicine. ¹

the applications in advanced endometrial carcinoma are based on results from study 309/keynote-775, in which lenvima plus keytruda demonstrated statistically significant improvements in pfs, os and orr versus chemotherapy (investigator’s choice of doxorubicin or paclitaxel), regardless of mismatch repair (mmr) status. these data were presented in march at the virtual society of gynecologic oncology (sgo) 2021 annual meeting on women’s cancer. study 309/keynote-775 is the confirmatory trial for study 111/keynote-146, which supported the 2019 accelerated approval of the combination for the treatment of patients with advanced endometrial carcinoma that is not microsatellite instability-high (msi-h) or mismatch repair deficient (dmmr), who have disease progression following prior systemic therapy and are not candidates for curative surgery or radiation. this indication was an accelerated approval based on tumor response and durability of response and reviewed under the fda’s real-time oncology review pilot program and the fda’s project orbis. continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trial.

eisai and merck & co., inc., kenilworth, n.j., u.s.a. are studying the lenvima plus keytruda combination through the leap (lenvatinib and pembrolizumab) clinical program in 14 different tumor types (endometrial carcinoma, hepatocellular carcinoma, melanoma, non-small cell lung cancer, renal cell carcinoma, squamous cell carcinoma of the head and neck, urothelial cancer, biliary tract cancer, colorectal cancer, gastric cancer, glioblastoma, ovarian cancer, pancreatic cancer and triple-negative breast cancer) across more than 20 clinical trials.

 

about lenvima^® (lenvatinib) capsules

lenvima, discovered and developed by eisai, is an orally available kinase inhibitor that inhibits the kinase activities of vascular endothelial growth factor (vegf) receptors vegfr1 (flt1), vegfr2 (kdr), and vegfr3 (flt4). lenvima inhibits other kinases that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (fgf) receptors fgfr1-4, the platelet derived growth factor receptor alpha (pdgfrα), kit, and ret. in syngeneic mouse tumor models, lenvima decreased tumor-associated macrophages, increased activated cytotoxic t cells, and demonstrated greater antitumor activity in combination with an anti-pd-1 monoclonal antibody compared to either treatment alone.

currently, lenvima has been approved for monotherapy as a treatment for thyroid cancer in over 70 countries including japan, in europe, china and in asia, and in the united states for radioiodine-refractory differentiated thyroid cancer. in addition, lenvima has been approved for monotherapy as a treatment for unresectable hepatocellular carcinoma in over 70 countries including japan, the united states, in europe, china and in asia. it is also approved in combination with everolimus as a treatment for renal cell carcinoma following prior antiangiogenic therapy in over 60 countries, including the united states, in europe and asia. in europe, the agent was launched under the brand name kisplyx^® for renal cell carcinoma. in addition, it is approved in combination with keytruda (generic name: pembrolizumab) as a treatment for advanced endometrial carcinoma that is not microsatellite instability-high (msi-h) or mismatch repair deficient (dmmr) who have disease progression following prior systemic therapy and are not candidates for curative surgery or radiation in over 10 countries including the united states, canada and australia. continued approval for this indication is contingent upon verification and description of clinical benefit in the confirmatory trials. lenvima has also been approved for monotherapy as a treatment for unresectable thymic carcinoma in japan.

 

about keytruda^® (pembrolizumab) injection, 100mg

keytruda is an anti-pd-1 therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. keytruda is a humanized monoclonal antibody that blocks the interaction between pd-1 and its ligands, pd-l1 and pd-l2, thereby activating t lymphocytes which may affect both tumor cells and healthy cells.

merck & co., inc., kenilworth, n.j., u.s.a. has the industry’s largest immuno-oncology clinical research program. there are currently more than 1,400 trials studying keytruda across a wide variety of cancers and treatment settings. the keytruda clinical program seeks to understand the role of keytruda across cancers and the factors that may predict a patient’s likelihood of benefitting from treatment with keytruda, including exploring several different biomarkers.

 

about clear study (study 307/keynote-581)

the clear study (study 307/keynote-581) is a multicenter, randomized, open-label, phase 3 trial (clinicaltrials.gov, ) evaluating lenvima in combination with keytruda or in combination with everolimus versus sunitinib for the first-line treatment of patients with advanced rcc. the primary endpoint is pfs, as assessed by independent review per response evaluation criteria in solid tumors (recist) v1.1. key secondary endpoints include os, orr and safety. a total of 1,069 patients were randomized (1:1:1) to receive lenvima (20 mg orally once daily) in combination with keytruda (200 mg intravenously [iv] every three weeks for up to 24 months); or lenvima (18 mg orally once daily) in combination with everolimus (5 mg orally once daily); or sunitinib (50 mg orally once daily for four weeks on treatment, followed by two weeks off treatment).

in the trial’s primary endpoint of pfs, as assessed by independent review per recist v1.1, lenvima plus keytruda reduced the risk of disease progression or death by 61% (hr=0.39 [95% ci: 0.32-0.49]; p<0.001), with a median pfs of 23.9 months (95% ci: 20.8-27.7) versus 9.2 months (95% ci: 6.0-11.0) for patients who received sunitinib. in the trial’s key secondary endpoints, lenvima plus keytruda reduced the risk of death by 34% (hr=0.66 [95% ci: 0.49-0.88]; p=0.005) versus patients who received sunitinib. median os was not reached in either treatment arm after a median follow-up of 27 months. treatment with lenvima plus keytruda resulted in an orr of 71.0% (95% ci: 66.3-75.7), with a complete response (cr) rate of 16.1% and a partial response (pr) rate of 54.9%, versus an orr of 36.1% (95% ci: 31.2-41.1), with a cr rate of 4.2% and a pr rate of 31.9%, for patients who received sunitinib (relative risk=1.97 [95% ci: 1.69-2.29]). median duration of response (dor) for patients who received lenvima plus keytruda was 25.8 months (95% ci: 22.1-27.9) versus 14.6 months (95% ci: 9.4-16.7) for patients who received sunitinib.

in the lenvima plus keytruda arm, treatment-related adverse events (traes) led to discontinuation of lenvima in 18.5% of patients, of keytruda in 25.0% of patients, and of both in 9.7% of patients. in the sunitinib arm, traes led to discontinuation of sunitinib in 10.0% of patients. grade 5 traes occurred in 1.1% of patients in the lenvima plus keytruda arm versus 0.3% of patients in the sunitinib arm. grade ≥3 traes occurred in 71.6% of patients in the lenvima plus keytruda arm versus 58.8% of patients in the sunitinib arm. the most common traes of any grade occurring in at least 20% of patients in the lenvima plus keytruda arm were diarrhea (54.5%), hypertension (52.3%), hypothyroidism (42.6%), decreased appetite (34.9%), fatigue (32.1%) and stomatitis (32.1%). in the sunitinib arm, the most common traes of any grade occurring in at least 20% of patients were diarrhea (44.4%), hypertension (39.1%), stomatitis (37.4%), hand-foot syndrome (35.9%), fatigue (32.1%) and nausea (27.6%).

 

about study 309/keynote-775

study 309/keynote-775 is a multicenter, randomized, open-label, phase 3 trial (clinicaltrials.gov, ) evaluating lenvima in combination with keytruda in patients with advanced endometrial carcinoma who had been previously treated with at least one prior platinum-based chemotherapy regimen in any setting, including in the neoadjuvant and adjuvant settings. the dual primary endpoints are pfs, as assessed by blinded independent central review (bicr) per recist v1.1, and os. select secondary endpoints include orr and duration of response (dor), as assessed by bicr. a total of 827 patients were randomized (1:1) to receive lenvima (20 mg orally once daily) in combination with keytruda (200 mg iv every three weeks); or investigator’s choice of either doxorubicin (60 mg/m² iv every three weeks) or paclitaxel (80 mg/m² iv on a 28-day cycle, three weeks of receiving weekly paclitaxel and one week of not receiving paclitaxel).

the study met the dual primary endpoints of pfs, as assessed by bicr per recist v1.1, os, as well as the secondary efficacy endpoint of orr, as assessed by bicr per recist v1.1, in the all-comer population (pmmr and dmmr) and in the pmmr subgroup. median follow-up was 11.4 months for both the all-comer population and pmmr subgroup. a statistically significant improvement in pfs was seen in the all-comer population, in which lenvima plus keytruda (n=411) reduced the risk of disease progression or death by 44% (hr=0.56 [95% ci: 0.47-0.66]; p<0.0001), with a median pfs of 7.2 months (95% ci: 5.7-7.6; number of events=281) versus 3.8 months (95% ci: 3.6-4.2; number of events=286) for patients who received tpc (n=416). additionally, a statistically significant improvement in os was seen in the all-comer population, in which lenvima plus keytruda reduced the risk of death by 38% (hr=0.62 [95% ci: 0.51-0.75]; p<0.0001), with a median os of 18.3 months (95% ci: 15.2-20.5; number of events=188) versus 11.4 months (95% ci: 10.5-12.9; number of events=245) for patients who received tpc. the safety profile of lenvima plus keytruda was generally consistent with the established safety profiles of the individual monotherapies.

in the all-comer population, the secondary efficacy endpoint of orr was 31.9% (95% ci: 27.4-36.6), with a cr rate of 6.6% and a pr rate of 25.3%, for patients who received lenvima plus keytruda versus 14.7% (95% ci: 11.4-18.4), with a cr rate of 2.6% and a pr rate of 12.0% for patients who received tpc (orr difference versus tpc: 17.2 percentage points; p<0.0001). for patients who responded, the median duration of response (dor) was 14.4 months (range: 1.6-23.7) for patients who received lenvima plus keytruda versus 5.7 months (range: 0.0-24.2) for patients who received tpc.

results were similar across the all-comer population and the pmmr subgroup. in the pmmr subgroup, lenvima plus keytruda reduced the risk of disease progression or death by 40% (hr=0.60 [95% ci: 0.50-0.72]; p<0.0001), with a median pfs of 6.6 months (95% ci: 5.6-7.4; number of events=247) versus 3.8 months (95% ci: 3.6-5.0; number of events=238) for patients who received tpc. lenvima plus keytruda reduced the risk of death by 32% (hr=0.68 [95% ci: 0.56-0.84]; p =0.0001), with a median os of 17.4 months (95% ci: 14.2-19.9; number of events=165) versus 12.0 months (95% ci: 10.8-13.3; number of events=203) for patients who received tpc. the secondary endpoint of orr was 30.3% (95% ci: 25.5-35.5), with a cr rate of 5.2% and a pr rate of 25.1%, for patients who received lenvima plus keytruda versus 15.1% (95% ci: 11.5-19.3), with a cr rate of 2.6% and a pr rate of 12.5%, for patients who received tpc (orr difference versus tpc: 15.2 percentage points: p<0.0001). for patients who responded, the median dor was 9.2 months (range: 1.6-23.7) for patients who received lenvima plus keytruda versus 5.7 months (range: 0.0-24.2) for patients who received tpc.

in the all-comer population, in the lenvima plus keytruda arm (n=406), any grade treatment-emergent adverse events (teaes) led to discontinuation of lenvima in 30.8% of patients, of keytruda in 18.7% of patients, and of both in 14.0% of patients. in the tpc arm (n=388), any grade teaes led to discontinuation of chemotherapy in 8.0% of patients. grade 5 teaes of any cause occurred in 5.7% of patients in the lenvima plus keytruda arm and in 4.9% of patients in the tpc arm. grade ≥3 teaes occurred in 88.9% of patients in the lenvima plus keytruda arm and in 72.7% of patients in the tpc arm. in the lenvima plus keytruda arm, the most common teaes of any grade occurring in at least 25% of patients were hypertension (64.0%), hypothyroidism (57.4%), diarrhea (54.2%), nausea (49.5%), decreased appetite (44.8%), vomiting (36.7%), weight decrease (34.0%), fatigue (33.0%), arthralgia (30.5%), proteinuria (28.8%), anemia (26.1%), constipation (25.9%), and urinary tract infection (25.6%). in the tpc arm, the most common teaes of any grade occurring in at least 25% of patients were anemia (48.7%), nausea (46.1%), neutropenia (33.8%), alopecia (30.9%), and fatigue (27.6%). median treatment duration was 231 days (range: 1-817) with lenvima plus keytruda and 104.5 days (range: 1-785) with tpc.

 

about renal cell carcinoma (rcc)^2,3,4,5,6,7

worldwide, it is estimated there were more than 431,000 new cases of kidney cancer diagnosed and more than 179,000 deaths from the disease in 2020. in japan, there were more than 25,000 new cases and 8,000 deaths in 2020. in the u.s. alone, it is estimated there will be more than 76,000 new cases of kidney cancer diagnosed and almost 14,000 deaths from the disease in 2021. renal cell carcinoma is by far the most common type of kidney cancer; about nine out of 10 kidney cancers are rccs. renal cell carcinoma is about twice as common in men as in women. most cases of rcc are discovered incidentally during imaging tests for other abdominal diseases. approximately 30% of patients with rcc will have metastatic disease at diagnosis, and as many as 40% will develop metastases after primary surgical treatment for localized rcc. survival is highly dependent on the stage at diagnosis, and the five-year survival rate is 13% for patients with metastatic disease.

 

about endometrial carcinom^8,9,10,11,12

endometrial carcinoma begins in the inner lining of the uterus, which is known as the endometrium, and is the most common type of cancer in the uterus. in 2020, it was estimated there were more than 417,000 new cases and more than 97,000 deaths from uterine body cancers worldwide (these estimates include both endometrial cancers and uterine sarcomas; more than 90% of uterine body cancers occur in the endometrium, so the actual numbers for endometrial cancer cases and deaths are slightly lower than these estimates). in japan, there were more than 17,000 new cases of uterine body cancer and more than 3,000 deaths from the disease in 2020. in the u.s., it is estimated there will be more than 66,000 new cases of uterine body cancer and nearly 13,000 deaths from the disease in 2021. the five-year survival rate for metastatic endometrial cancer (stage iv) is estimated to be approximately 17%.

results from new analysis evaluating health-related quality of life (hrqol) based on patient-reported outcomes using three hrqol scales

 

tokyo and kenilworth, n.j., june 7, 2021 – eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) and merck & co., inc., kenilworth, n.j., u.s.a. (known as msd outside the united states and canada) today announced new investigational data from the pivotal phase 3 clear(study 307)/keynote-581 trial, which evaluated the combinations of lenvima, the orally available multiple receptor tyrosine kinase inhibitor discovered by eisai, plus keytruda, the anti-pd-1 therapy from merck & co., inc., kenilworth, n.j., u.s.a., and lenvima plus everolimus versus sunitinib for the first-line treatment of patients with advanced renal cell carcinoma (rcc). results from a new analysis evaluating health-related quality of life (hrqol) based on patient-reported outcomes are being presented during an oral abstract session at the 2021 american society of clinical oncology (asco) annual meeting (abstract #4502). data from clear/keytnote-581 were originally presented at the 2021 genitourinary cancers symposium (asco gu) and published in the new england journal of medicine, and data from this trial are currently under review with the u.s. food and drug administration (fda).

“this new analysis expands our understanding of the results we’ve seen from the clear/keynote-581 trial in the treatment of patients with advanced renal cell carcinoma,” said dr. robert motzer, medical oncologist, kidney cancer section head, genitourinary oncology service, memorial sloan kettering cancer center. “the additional data showed an improvement of specific health-related quality of life measures for patients who received lenvima plus keytruda compared with sunitinib, supporting the importance of this combination as a potential new first-line treatment option for patients.”

“we continue to see an increasing number of patients diagnosed with advanced renal cell carcinoma and remain committed to improving outcomes for those facing this difficult-to-treat disease,” said dr. gregory lubiniecki, vice president, oncology clinical research, merck & co., inc., kenilworth, n.j., u.s.a. research laboratories. “this new analysis builds on earlier findings from the clear/keynote-581 trial and further supports the potential use of keytruda plus lenvima for the treatment of patients in the first-line setting.”

“this analysis addresses questions of interest to healthcare professionals who treat patients with advanced renal cell carcinoma and reinforces the lenvima plus keytruda combination as a possible new treatment option for patients with this disease,” said dr. takashi owa, chief medicine creation officer and chief discovery officer, oncology business group at eisai. “these results reflect eisai and merck’s shared commitment to relentlessly pursue thorough scientific investigations with the goal of improving cancer care.”

in an analysis of a secondary endpoint of hrqol scores in the clear/keynote-581 trial, lenvima plus keytruda and lenvima plus everolimus were evaluated to determine the impact on hrqol compared to sunitinib in patients with advanced rcc. this was assessed based on patient-reported outcomes using three hrqol and symptom measures: functional assessment of cancer therapy kidney symptom index – disease-related symptoms (fksi-drs), european organisation for research and treatment of cancer quality of life questionnaire for patients with cancer – core 30 (eortc qlq-c30) and european quality of life five-dimensions – 3-level system (euroqol eq-5d-3l). unless otherwise noted, hrqol analyses were based on data from randomized patients who received at least one dose of study treatment. no adjustments for multiple testing or estimation were used; p-values (two-sided) and confidence intervals (ci) are nominal and descriptive. longitudinal change from baseline was assessed by mixed model analysis. least squares mean differences (lsmd) and 95% ci were calculated from baseline. time to deterioration (based on changes in hrqol and disease-related symptom scores ≥ meaningful thresholds) was assessed using time to first deterioration (ttd), which is the number of weeks between randomization and the first deterioration event, and time until definitive deterioration (tudd), which is the number of weeks between randomization and the earliest deterioration event with no subsequent recovery above the deterioration threshold or no subsequent hrqol assessment data. all times to deterioration were calculated and compared using the kaplan-meier method, stratified log-rank tests and cox models.

lenvima plus keytruda demonstrated similar changes from baseline at mean follow-up (week 46) on 14 out of 18 hrqol and disease-related symptom scores and better hrqol and disease-related symptom scores for the following measures ( lsmd [95% ci]): physical functioning (3.01 [0.48, 5.54]), fatigue (-2.80 [-5.52, -0.08]), dyspnea (-2.79 [-5.33, -0.25]) and constipation (-2.19 [-4.19, -0.18]), as measured by the qlq-c30, versus sunitinib. lenvima plus everolimus demonstrated similar changes from baseline at mean follow-up (week 46) on 14 out of 18 hrqol and disease-related symptom scores and worse hrqol and disease-related symptom scores in the following measures (lsmd [95% ci]): global health score/qol (-2.81[-5.08, -0.54]), pain (2.80 [0.11, 5.49]), appetite loss (4.23 [1.34, 7.13]) and diarrhea (5.26 [2.61, 7.91]) compared to sunitinib.

lenvima plus keytruda demonstrated a similar ttd in 14 out of 18 hrqol and disease-related symptom scores, and a delay in ttd for physical functioning, dyspnea, appetite loss, and eq-5d visual analog scale compared to sunitinib. lenvima plus keytruda demonstrated a delay in tudd in 16 out of 18 hrqol and disease-related symptom scores and a similar tudd for cognitive functioning and financial difficulties compared to sunitinib.

about lenvima^® (lenvatinib) capsules

lenvima, discovered and developed by eisai, is an orally available kinase inhibitor that inhibits the kinase activities of vascular endothelial growth factor (vegf) receptors vegfr1 (flt1), vegfr2 (kdr), and vegfr3 (flt4). lenvima inhibits other kinases that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (fgf) receptors fgfr1-4, the platelet derived growth factor receptor alpha (pdgfrα), kit, and ret. in syngeneic mouse tumor models, lenvatinib decreased tumor-associated macrophages, increased activated cytotoxic t cells, and demonstrated greater antitumor activity in combination with an anti-pd-1 monoclonal antibody compared to either treatment alone. the combination of lenvatinib and everolimus showed increased anti-angiogenic and anti-tumor activity as demonstrated by decreases in human endothelial cell proliferation, tube formation, and vegf signaling in vitro and decreases in tumor volume in mouse xenograft models of human renal cell cancer greater than those with either drug alone.

currently, lenvima has been approved for monotherapy as a treatment for thyroid cancer in over 70 countries including japan, in europe, china and in asia, and in the united states for radioiodine-refractory differentiated thyroid cancer. in addition, lenvima has been approved for monotherapy as a treatment for unresectable hepatocellular carcinoma in over 70 countries including japan, the united states, in europe, china and in asia. it is also approved in combination with everolimus as a treatment for renal cell carcinoma following prior antiangiogenic therapy in over 60 countries, including the united states, in europe and asia. in europe, the agent was launched under the brand name kisplyx^® for renal cell carcinoma. in addition, it is approved in combination with keytruda as a treatment for advanced endometrial carcinoma that is not microsatellite instability-high (msi-h) or mismatch repair deficient (dmmr) who have disease progression following prior systemic therapy and are not candidates for curative surgery or radiation in over 10 countries including the united states, canada and australia. continued approval for this indication is contingent upon verification and description of clinical benefit in the confirmatory trials. lenvima has also been approved for monotherapy as a treatment for unresectable thymic carcinoma in japan.
