eisai’s anti-microtubule binding region (mtbr) tau antibody e2814 previously selected as the first investigational therapy among anti-tau drugs for the dian-tu tau next generation trial

 

eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) announced today that the dominantly inherited alzheimer network trials unit (dian-tu), led by washington university school of medicine in st. louis, has an agreement with the u.s. food and drug administration (fda) and the european medicines agency (ema) to amend the clinical study (tau nexgen) design to include a background anti-amyloid agent. the tau nexgen clinical study was originally designed to focus on therapies that target tau. with increasing evidence from clinical studies showing that targeting amyloid can reduce biomarkers of alzheimer’s disease (ad), the tau nexgen clinical trial leaders selected eisai’s investigational anti-amyloid beta (aβ) protofibril antibody lecanemab as the background anti-amyloid agent.

the purpose of the tau nexgen study is to assess the safety, tolerability, biomarker and cognitive efficacy of investigational therapies in people who have an alzheimer’s disease-causing gene mutation. the study will evaluate if treatment with study drug slows the rate of progression of cognitive impairment and improves disease-related biomarkers.

people who have this genetic mutation of dominantly inherited alzheimer’s disease (diad) are known to develop ad and will likely develop symptoms at around the same age their affected parents did, often in their 50s, 40s or even 30s. in march 2021, the dian-tu selected anti-microtubule binding region (mtbr) tau antibody e2814, which was created from collaboration research between eisai and university college london, as the first investigational medicine among anti-tau drugs for the dian-tu tau study.

in the amended tau nexgen study, symptomatic participants will be administered lecanemab for six months before being randomly assigned to also receive the anti-tau drug or a placebo. since amyloid plaques accumulate before tau tangles in ad, this study design allows the researchers to assess whether amyloid removal clears the way for the anti-tau drug to function most effectively. pre-symptomatic participants will be randomly assigned to receive the anti-tau drug or a placebo for a year before beginning lecanemab administration. by staggering the drugs in this way, the researchers will be able to evaluate the effects of the anti-tau drug alone before assessing the effects of the two drugs together. the primary endpoint is a slowing of tau accumulation in the brain in symptomatic participants, as seen on pet brain scans. as a secondary endpoint, the researchers will evaluate whether the investigational therapies affect levels of a specific kind of tau — phosphorylated tau 217 — in the cerebrospinal fluid of pre-symptomatic participants. if these primary and secondary endpoints are positive in the analysis two years after the start of study, the study will be extended for another two years to assess whether the drug slows cognitive decline and has further effects on tau pathology.

“with growing evidence that removing amyloid plaques has biologically beneficial effects on amyloid and tau, we believe that targeting both alzheimer’s disease pathologies — amyloid plaques and tau tangles — at the same time can provide the highest chance of success,” said principal investigator randall j. bateman, m.d., director of dian-tu and the charles f. and joanne knight distinguished professor of neurology at washington university.

“eisai’s anti-mtbr tau antibody e2814 was chosen as the first investigational therapy among anti-tau drugs for the groundbreaking dominantly inherited alzheimer network trials unit tau nexgen, which was originally designed to target tau proteins. the growing body of evidence suggesting the removal of amyloid plaque slows cognitive decline is creating new possibilities to potentially fight this devastating disease. eisai is proud that our investigational anti-amyloid beta protofibril antibody lecanemab has been selected as the background anti-amyloid agent in this arm of the study,” said lynn kramer, m.d., faan, chief clinical officer, neurology business group, eisai co., ltd. “in our , lecanemab 10 mg/kg biweekly dosing without titration, demonstrated robust clearance of the brain amyloid plaques from early stage of administration and slowed cognitive decline in people living with early ad. encouragingly, the rate of amyloid-related imaging abnormalities-edema/effusion for this same dosing was 9.9% with less than 2% being symptomatic.”

eisai positions neurology as a key therapeutic area, and it will continue to create innovation in the development of novel medicines based on cutting-edge neurology research as it seeks to contribute further to improving the benefits of affected individuals and their families in diseases with high unmet needs, such as dementia including ad. our vision is clear: a world free of neurodegeneration.

eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) announced today the presentation of data from the company’s extensive alzheimer’s disease (ad) pipeline, including six oral presentations that will provide deeper insights into lecanemab’s potential as a treatment for early ad. eisai initiated a rolling submission of a biologics license application (bla) for lecanemab, an investigational anti-amyloid beta (aβ) protofibril antibody, for the treatment of early ad, to the u.s. food and drug administration (fda) under the accelerated approval pathway in september 2021. the lecanemab data and additional research findings from eisai’s robust ad pipeline will be featured in 10 presentations, including five late breaker oral presentations, at the 14th clinical trials on alzheimer’s disease (ctad) conference, november 9-12, 2021, in boston, massachusetts and virtually.

“the findings eisai will present at ctad provide scientific insights into the potential role of lecanemab in the treatment of early alzheimer’s disease as well as the relationship between clearance of amyloid-beta plaque from the brain, changes in blood-based biomarkers and clinical outcomes,” said michael irizarry, m.d., vice president, deputy chief clinical officer, neurology business group, eisai inc. “we are working to advance lecanemab and our other targeted investigational compounds as quickly as possible in our commitment to bringing solutions to patients and their families.”

the focus on ad has historically been on alleviating cognitive, functional, and behavioral symptoms, but there has been significant progress in understanding the biological mechanisms of the disease and eisai’s investigational pipeline aims to treat the range of underlying pathophysiology, including amyloid, tau and neurodegeneration.

“with lecanemab’s rolling bla submission to the fda under the accelerated approval pathway, completion of enrollment of 1,795 patients in the confirmatory phase 3 clarity ad clinical trial, initiation of a lecanemab subcutaneous dosing phase 1 study and the ongoing phase 3 ahead 3-45 study in people with pre-clinical alzheimer’s disease, it is an exciting time for lecanemab and eisai’s ad franchise,” said ivan cheung, chairman, eisai inc., senior vice president, president neurology business group and global alzheimer’s disease officer, eisai co., ltd. “we are optimistic about the promise lecanemab and other investigational compounds in our robust pipeline may have for people living with alzheimer’s disease.”

eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) and prism biolab co., ltd. (headquarters: kanagawa, president and ceo: dai takehara, “prism”) announced today that the  creb-binding protein (cbp) / β-catenin inhibitor e7386, a medium-molecular weight compound created through collaboration research between eisai and prism, has achieved the clinical poc (proof of concept).

eisai is conducting a phase i clinical study of e7386 monotherapy for solid tumors, and a phase ib clinical trial of e7386 plus lenvatinib mesylate (product name: lenvima®, “lenvatinib”), the orally available multiple receptor tyrosine kinase inhibitor discovered by eisai, for solid tumors including hepatocellular carcinoma. the achievement of the poc, which is defined in a collaborative research agreement between eisai and prism, was confirmed based on data such as antitumor activity and changes of biomarkers in these clinical trials.

the e7386 targets, β-catenin, is considered to be one of the undruggable targets that are particularly difficult to develop into drug discovery. β-catenin, along with cbp, which is also the target of e7386, is located at the downstream of the wnt signaling and regulates the wnt signaling-dependent transcription activity. e7386 is a cbp / β-catenin inhibitor that inhibits cbp and β-catenin protein-protein interactions and regulates the wnt signal-dependent gene expression. it is expected to suppress tumor growth dependent on the wnt signaling. 1 e7386 is also expected to release the suppression of tumor-infiltrating t cells by the wnt signaling activation, and to enhance the effect of immune checkpoint inhibitors1. the antitumor effect of e7386 alone and the combination of e7386 and anti-pd-1 antibody has been confirmed in a cancer-bearing mouse model.

based on the poc achievement, eisai has initiated a phase ib/ii clinical trial (study 201) of e7386 in combination with anti-pd-1 therapy pembrolizumab for solid tumors in japan.*

dr. takashi owa, senior vice president, president of oncology business group, at eisai said, “with achieving the poc, we are confident with the prospect of offering e7386 to patients as a cancer treatment. e7386 may overcome lenvatinib and pembrolizumab treatment resistances through its combination therapy with lenvatinib or pembrolizumab. eisai will accelerate clinical trials of e7386 in combination with lenvatinib or pembrolizumab, and do its utmost aiming to create new treatments for cancers with high unmet medical needs.”

dai takehara, president and ceo of prism commented, “the approval of the clinical poc for the e7386 demonstrates that prism’s drug discovery platform is an effective option for novel drug targets which have been considered difficult. we are grateful to eisai for advancing this development. we will continue to take on the challenge of targeting more novel targets, with the aim of providing new treatment to as many patients as possible.”

positive opinion granted for advanced endometrial carcinoma based on significant os and pfs benefit compared to chemotherapy in study 309/keynote-775 trial

 

tokyo and kenilworth, n.j., oct. 18, 2021 – eisai (headquarters: tokyo, ceo: haruo naito) and merck & co., inc., kenilworth, n.j., u.s.a. (known as msd outside the united states and canada) today announced that the committee for medicinal products for human use (chmp) of the european medicines agency has adopted positive opinions recommending approval of the combination of lenvima® (marketed as kisplyx® in the european union [eu]  for the treatment of advanced renal cell carcinoma [rcc]), 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., for two different indications. one positive opinion is for the first-line treatment of adult patients with advanced rcc, and the other is for the treatment of adult patients with advanced or recurrent endometrial carcinoma (ec) who have disease progression on or following prior treatment with a platinum-containing therapy in any setting and are not candidates for curative surgery or radiation. decisions on the chmp’s recommendations will be given by the european commission for marketing authorization in the eu, and are expected in the fourth quarter of 2021. if approved, this would be the first combination of an anti-pd-1 therapy with a tyrosine kinase inhibitor approved for the treatment of two different types of cancer in the eu.

the positive chmp opinions are based on data from two pivotal phase 3 trials: clear (study 307)/keynote-581 evaluating the combination in adult patients with advanced rcc and study 309/keynote-775 evaluating the combination in certain patients with advanced ec.

in clear/keynote-581, lenvima plus keytruda demonstrated statistically significant improvements versus sunitinib in the efficacy outcome measures of overall survival (os), reducing the risk of death by 34% (hr=0.66 [95% ci, 0.49-0.88]; p=0.0049) versus sunitinib, and progression-free survival (pfs), reducing the risk of disease progression or death by 61% (hr=0.39 [95% ci, 0.32-0.49]; p<0.0001) with a median pfs of 23.9 months versus 9.2 months for sunitinib. additionally, the confirmed objective response rate was 71% (95% ci: 66-76) (n=252) for patients who received lenvima plus keytruda versus 36% with sunitinib (95% ci: 31-41) (n=129).

in study 309/keynote-775, lenvima plus keytruda demonstrated statistically significant improvements in the study’s dual efficacy outcome measures of os, reducing 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 versus 11.4 months for chemotherapy (investigator’s choice of doxorubicin or paclitaxel), and pfs, reducing 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 versus 3.8 months for chemotherapy (investigator’s choice of doxorubicin or paclitaxel).

“keytruda plus lenvima demonstrated a survival benefit for advanced renal cell carcinoma in the first-line setting and represents an important potential new treatment option for these patients. additionally, keytruda plus lenvima is the first anti-pd-1 and tyrosine kinase inhibitor combination to demonstrate a survival benefit in advanced endometrial carcinoma patients, and the benefit was shown regardless of mismatch repair status,” said dr. gregory lubiniecki, vice president, clinical research, merck & co., inc., kenilworth, n.j., u.s.a. research laboratories. “we are pleased that the chmp has recognized the important role of the combination therapy in these difficult-to-treat cancers.”

“we appreciate the positive opinions rendered by the eu chmp recommending approval of lenvima plus keytruda in advanced renal cell carcinoma and advanced endometrial carcinoma, underscoring the potential significance of the outcomes observed in the clear/keynote-581 and study 309/keynote-775 trials” said dr. takashi owa, president, oncology business group at eisai. “we are grateful to the patients who participated in these studies, their families and clinicians. their commitment made these meaningful milestones possible.”

in clear/keynote-581, the most common adverse reactions (≥30%) for lenvima plus keytruda* were diarrhoea (61.8%), hypertension (51.5%) fatigue (47.1%), hypothyroidism (45.1%), decreased appetite (42.1%), nausea (39.6%), stomatitis (36.6%), proteinuria (33.0%), dysphonia (32.8%), and arthralgia (32.4%).

“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 carcinom8,9,10,11,12

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%.
