"These results add to a growing body of evidence supporting the role of poziotinib in patients with EGFR and HER2 exon 20 mutations, and are a real advance for these patients for whom no targeted therapies have been effective so far," said John Heymach, M.D., Ph.D., Chairman and Professor, Department of Thoracic/Head and Neck Medical Oncology, University of Texas, MD Anderson Cancer Center. "I am highly encouraged by these results and the evolution of poziotinib data. Our study is the single largest data set in this high unmet need patient population and I am excited to present updated data during an oral session at the IASLC World Conference on Lung Cancer."

Data appearing in the abstract were current as of May 3, 2018. 40 patients of the 50 patient EGFR cohort had data available for the efficacy analysis. In the 40 patients, poziotinib continued to show robust efficacy with an objective response rate (ORR) of 58% in this heavily pre-treated population. Median progression free survival (PFS) was 5.6 months (95%-CI 5.06-NA). The disease control rate was 90%. In the HER2 cohort the ORR was 50% and the disease control rate was 83%. The most common adverse events were skin-rash (27.5%), diarrhea (12.5%), and paronychia (7.5%). 45.0% of patients required dose reduction to 12mg, while 17.5% of patients required dose reduction to 8mg. Updated data will be presented at the conference and will include data into September.

"We are thrilled with the data presented in the abstract and look forward to a more robust data set on September 24th," said Joe Turgeon, President and CEO of Spectrum Pharmaceuticals. "Additionally, we believe the treatment potential of poziotinib may go well beyond the previously treated lung cancer setting. We are actively expanding the poziotinib clinical program to explore poziotinib in new areas including first-line treatment of NSCLC, treatment of other solid tumors with EGFR or HER2 mutations, and combination therapies."

Spectrum Pharmaceuticals will be hosting a live webcast on September 24 following the oral presentation.

Abstract: A Phase II Trial of Poziotinib in EGFR and HER2 exon 20 Mutant Non-Small Cell Lung Cancer

Background

Insertions/mutations in exon 20 of EGFR and HER2 occur in ~1% and ~3% of all lung adenocarcinomas, respectively. These alterations are characterized by primary resistance to approved tyrosine kinase inhibitors (TKIs) with response rates of <12%. We have previously shown that exon 20 insertions restrict the size of the drug-binding pocket, limiting binding of large inhibitors. However, poziotinib can circumvent these steric changes and is a potent inhibitor of EGFR and HER2 exon 20 mutants (Robichaux et al. Nat Med). Herein, we report the results of an investigator-initiated study of poziotinib in EGFR and HER2 exon 20 mutant NSCLC (NCT03066206).

Methods

Patients ≥18yrs with locally advanced/metastatic NSCLC bearing mutations/insertions in EGFR or HER2 exon 20 (except EGFR T790M) were eligible. Unlimited prior systemic and targeted therapies were permitted. Poziotinib 16mg PO daily was administered until progression, death, or withdrawal. The primary endpoint was objective response rate (ORR) based on RECIST v1.1. Response was evaluated every eight weeks. A Bayesian design was used with a plan to enroll patients in cohorts of 10 and to terminate the study if ORR was ≤20%. Secondary endpoints included disease control rate (DCR); progression-free survival (PFS); overall survival; and safety.

Results

As of May 3, 2018, the planned EGFR cohort of 50 patients was fully enrolled, and 40 patients were evaluated for response. Median age was 55yrs (range 29-78). 65.1% of patients had received at least two prior lines of therapy for metastatic disease. 60% of patients had ≥grade 3 adverse events; most common were skin-rash (27.5%), diarrhea (12.5%), and paronychia (7.5%). 45.0% of patients required dose reduction to 12mg, while 17.5% of patients required dose reduction to 8mg. One patient stopped the treatment due to grade 3 skin rash. The ORR at eight weeks was 58% (95%-CI 40.9-73.0) and the DCR was 90% (95%-CI 76.3-97.2). Among 23 patients who achieved partial response, 15 responses were confirmed, five responses were unconfirmed, and three patients are pending confirmation. Responses were observed in 8/13 (62%) patients that were previously treated with TKI. Median PFS was 5.6mo (95%-CI 5.06-NA). Furthermore, 13 patients were enrolled in the HER2 cohort. Observed toxicities were similar to the EGFR cohort except one case of grade 5 pneumonitis, assessed to be possibly drug related. Twelve patients were evaluated for response with an ORR of 50% (95% CI 21.1-78.9) at eight weeks and a DCR of 83%.

Conclusion

The trial exceeded the stopping boundary of ORR of 20%. In a heavily pre-treated population with EGFR and HER2 exon 20 mutant NSCLC, poziotinib provides a high ORR, an encouraging PFS, and a manageable toxicity profile.

About Poziotinib

Poziotinib is a novel, orally available Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR TKI) that inhibits the tyrosine kinase activity of EGFR as well as HER2 and HER4. Importantly this, in turn, leads to the inhibition of the proliferation of tumor cells that overexpress these receptors. Mutations or overexpression/amplification of EGFR family receptors have been associated with a number of different cancers, including non-small cell lung cancer (NSCLC), breast cancer, and gastric cancer. Spectrum received an exclusive license from Hanmi Pharmaceuticals to develop, manufacture, and commercialize worldwide excluding Korea and China. Poziotinib is currently being investigated by Spectrum and Hanmi in several mid-stage trials in multiple solid tumor indications.

The poziotinib NSCLC clinical program for patients with EGFR or HER2 exon 20 insertion mutations currently consists of a Phase 2 investigator-initiated study at The University of Texas MD Anderson Cancer Center and a Phase 2 pivotal, Spectrum-sponsored, multi-center, global study (ZENITH20) with active sites in the United States and future centers planned in Canada and Europe.

EISAI AND MERCK & CO., INC., KENILWORTH, N.J., U.S.A. ANNOUNCE CHINA NATIONAL MEDICAL PRODUCTS ADMINISTRATION (NMPA) APPROVAL OF LENVIMA® (LENVATINIB) FOR TREATMENT OF UNRESECTABLE HEPATOCELLULAR CARCINOMA (HCC)

On September 5, 2018 Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, "Eisai") and Merck & Co., Inc., Kenilworth N.J., U.S.A., known as MSD outside of the United States and Canada, reported that the China National Medical Products Administration (NMPA) approved the kinase inhibitor LENVIMA (lenvatinib) as a single agent for the treatment of patients with unresectable hepatocellular carcinoma (HCC) who have not received prior systemic therapy (Press release, Eisai, SEPT 5, 2018, View Source [SID1234529337]). In China, the application of LENVIMA was submitted in October 2017, and was designated for Priority Review by the NMPA due to LENVIMA’s significant clinical benefit compared to existing treatments, leading to approval in approximately 10 months. This approval marks the first for LENVIMA in China, where the incidence of HCC is high,1 and the first new systemic therapy approved for the first-line treatment of unresectable HCC in China in ten years.1

The approval was based on results from the REFLECT study (Study 304),2 an open-label, Phase 3 trial where LENVIMA demonstrated a treatment effect on overall survival (OS)*1 by statistical confirmation of non-inferiority when compared with the standard of care, sorafenib, in 954 patients with previously untreated unresectable HCC. LENVIMA demonstrated statistically significant superiority and clinically meaningful improvements in progression-free survival (PFS)*2, time to progression (TTP)*3 and objective response rate (ORR)*4. In a subpopulation analysis of 288 patients in the study from the greater Chinese region (mainland China, Hong Kong and Taiwan), LENVIMA demonstrated efficacy based on non-inferiority of OS compared to sorafenib, with improvements also observed in PFS, TTP and ORR3. Approximately 80% of patients in the subpopulation were living with HCC resulting from chronic hepatitis B virus (HBV), which has high unmet medical need. For these patients, LENVIMA demonstrated non-inferiority based on OS compared with sorafenib, thereby demonstrating the effect of LENVIMA in patients with HCC resulting from HBV. (For the detailed data, please refer to "Notes for Editors" below.)

In the China package insert, the five most common adverse reactions observed in patients treated with LENVIMA were hypertension (45%), fatigue (44%), diarrhea (39%), decreased appetite (34%) and decreased weight (31%), which is consistent with the known side-effect profile of LENVIMA.

Liver cancer is the second leading cause of cancer-related deaths and is estimated to be responsible for approximately 750,000 deaths per year globally. Additionally, approximately 780,000 cases are newly diagnosed each year, about 80% of which occur in Asian regions. Specifically, in China, there are approximately 395,000 new cases and 380,000 deaths per year, accounting for approximately 50% of cases worldwide.1 HCC accounts for 85% to 90% of primary liver cancer cases. Unresectable HCC, for which treatment options are limited, is extremely difficult to treat, and the development of new treatments is necessary.

Since the initial launch, more than 10,000 patients have been treated with LENVIMA. Today, LENVIMA is approved as a treatment for refractory thyroid cancer in over 50 countries including the United States, Japan, in Europe and Asia, and as combination with everolimus as a second-line treatment for renal cell carcinoma (RCC) in over 45 countries including the United States and in Europe. For HCC, LENVIMA was approved for use in Japan in March 2018, and in the United States and Europe in August 2018. In Japan, approximately 3,000 HCC patients have been treated with LENVIMA since approval of this indication.

*1 Overall Survival (OS): The time period from the commencement of cancer treatment up until death by any cause. Whether the cause of death is cancer or not is not taken into consideration for this variable.

*2 Progression Free Survival (PFS): PFS is the objectively confirmed time from the commencement of cancer treatment to the date of disease progression, or date of death from any cause, whichever occurs first.

*3 Time To Progression: TTP is the objectively confirmed time from the commencement of cancer treatment to the date of disease progression. Unlike PFS, TTP does not consider death from any cause.

*4 Objective Response Rate (ORR): ORR is the combined proportion of patients whose tumor was eliminated (complete response) and whose tumor was reduced by over 30% in size (partial response) as verified by imaging assessment.

About the REFLECT Trial (Study 304) 2

REFLECT was a large (n=954) Phase 3, randomized, multicenter, open-label trial conducted by Eisai to compare the efficacy and safety of LENVIMA versus sorafenib as a first-line systemic treatment in patients with unresectable HCC. Patients at 154 trial sites in 20 countries were randomized to receive LENVIMA 12 mg or 8 mg once a day depending on body weight (≥60 kg or <60 kg, respectively) (n=478) or sorafenib 400 mg twice a day (n=476). Treatment was continued until disease progression or unacceptable toxicity. The primary endpoint of this study was OS, tested first for non-inferiority to sorafenib, then for superiority. The key secondary efficacy endpoints of this study included PFS, TTP and ORR, tested for superiority to sorafenib.

In the China package insert, REFLECT showed that LENVIMA achieved the primary endpoint, demonstrating a treatment effect on OS by statistical confirmation of non-inferiority to sorafenib. Patients treated with LENVIMA experienced a median OS of 13.6 months compared to 12.3 months with sorafenib (Hazard Ratio [HR]: 0.92; 95% Confidence Interval [CI]: 0.79-1.06). Patients randomized to the LENVIMA arm did not have a statistically significant improvement in OS compared to those in the sorafenib arm. In addition, LENVIMA showed statistically significant superiority and clinically meaningful improvements in the secondary efficacy endpoints of PFS, TTP and ORR, as confirmed by a blinded independent imaging review:

• Median PFS was doubled with LENVIMA compared to sorafenib: 7.3 months versus 3.6 months (HR: 0.64; 95% CI: 0.55–0.75; p<0.00001) per blinded independent imaging review based on mRECIST criteria.
• Median TTP was doubled with LENVIMA compared to sorafenib: 7.4 months versus 3.7 months (HR: 0.60; 95% CI: 0.51–0.71; p<0.00001) per blinded independent imaging review based on mRECIST criteria.
• LENVIMA showed nearly 3.5 times the ORR of sorafenib: 40.6% (95% CI: 36.2-45.0) versus 12.4% (95% CI: 9.4-15.4) per blinded independent imaging review based on mRECIST criteria (odds ratio 5.01, 95% CI: 3.59-7.01; p<0.00001).

About the Subpopulation Analysis of Patients from the Greater Chinese Region3

The results of subpopulation analysis of patients from the greater Chinese region3 were based on 288 patients out of the 954 HCC patients who participated in the REFLECT study. In this subpopulation analysis, median OS was 15.0 months for LENVIMA versus 10.2 months for sorafenib (HR: 0.73; 95% CI: 0.55-0.96; nominal p=0.02620). Independent imaging review based on mRECIST criteria revealed the following results: PFS (LENVIMA 8.4 months versus sorafenib 3.6 months in median [HR: 0.47; 95% CI: 0.35-0.64; nominal p<0.00001]), TTP (LENVIMA 9.2 months versus sorafenib 3.6 months in median [HR: 0.45; 95% CI: 0.33-0.62; nominal p<0.00001]) and ORR (LENVIMA 43.8% versus sorafenib 13.2% [odds ratio 5.14; 95% CI: 2.84-9.31; nominal p<0.00001]).

Additionally, of the 288 patients in the subpopulation, approximately 80% (n=242) were living with HCC resulting from HBV. An analysis of these patients revealed the following results for OS: LENVIMA (n=123) 14.9 months versus sorafenib (n=119) 9.9 months in median (HR: 0.72; 95% CI: 0.53-0.97).

About Unresectable Hepatocellular Carcinoma (HCC)

Liver cancer is the second leading cause of cancer-related deaths and is estimated to be responsible for 750,000 deaths per year globally. Additionally, 780,000 cases are newly diagnosed each year.2 There is a large regional difference, with about 80% of new cases occurring in Asian regions, including China and Japan. HCC accounts for 85% to 90% of primary liver cancer cases. HCC is associated with chronic liver disease, in particular cirrhosis. Major causes of cirrhosis include hepatitis B virus and hepatitis C virus. However, according to a recent investigation, non-B/non-C HCC is on the rise. Surgery is the first option for treatment, but for patients with unresectable HCC who are not amenable for potentially curative therapeutic interventions, which include liver transplant, surgical resection and tumor ablation (typically radiofrequency ablation or cryotherapy), or who are not suitable for transarterial chemoembolization (TACE), treatment options are limited and the prognosis is very poor.

About LENVIMA (lenvatinib mesylate)

Discovered and developed in-house by Eisai, LENVIMA is an orally administered kinase inhibitor with a novel binding mode that selectively inhibits the multi activities of vascular endothelial growth factor (VEGF) receptors (VEGFR1, VEGFR2 and VEGFR3) and fibroblast growth factor (FGF) receptors (FGFR1, FGFR2, FGFR3 and FGFR4) in addition to other pathway-related RTKs (including the platelet-derived growth factor (PDGF) receptor PDGFRα; KIT; and RET) involved in tumor angiogenesis, tumor progression and modification of tumor immunity.

Currently, Eisai has obtained approval for LENVIMA as a treatment for refractory thyroid cancer in over 50 countries, including the United States, Japan, in Europe and Asia. Additionally, Eisai has obtained approval for the agent in combination with everolimus as a second-line treatment for RCC in over 45 countries, including the United States and in Europe. In Europe, the agent was launched under the brand name Kisplyx for RCC.

In addition, LENVIMA has been approved as a treatment for hepatocellular carcinoma in Japan, the United States, Europe and South Korea. Eisai has submitted applications for an indication covering hepatocellular carcinoma in Taiwan (December 2017), as well as in other countries.

It is important to note that the dose for LENVIMA for patients with unresectable HCC is based on the patient’s weight (12 mg for patients weighing 60 kilograms or more, 8 mg for patients weighing less than 60 kilograms); the recommended dosage and dose adjustments are described in the full prescribing information.

Roche Provides Update on Supplemental Biologics License Application (sBLA) for TECENTRIQ in First-line Metastatic Non-Squamous NSCLC

On September 05 2018, Roche reported that it was notified by the U.S. Food and Drug Administration (FDA) that the review period for the supplemental Biologics License Application (sBLA) for TECENTRIQ (atezolizumab) in combination with Avastin (bevacizumab), carboplatin and paclitaxel for the initial treatment of people with metastatic non-squamous non-small cell lung cancer (NSCLC) has been extended by three months (Press release, Hoffmann-La Roche, SEP 5, 2018, View Source [SID1234529354]). The extension allows the FDA time to review additional information requested in support of the sBLA. FDA determined that the submission of this information constituted a major amendment to the sBLA resulting in this extension of the PDUFA goal date. The FDA is expected to make a decision on approval by December 05, 2018. In May 2018, TECENTRIQ in combination with Avastin, carboplatin and paclitaxel was granted Priority Review from the FDA for the initial treatment of people with metastatic non-squamous NSCLC based on results from the Phase III IMpower150 study.

About NSCLC
Lung cancer is the leading cause of cancer death globally.[1] Each year 1.59 million people die as a result of the disease; this translates into more than 4,350 deaths worldwide every day.[2] Lung cancer can be broadly divided into two major types: NSCLC and small cell lung cancer. NSCLC is the most prevalent type, accounting for around 85% of all cases.[2] NSCLC comprises non-squamous and squamous-cell lung cancer, the squamous form of which is characterised by flat cells covering the airway surface when viewed under a microscope. The squamous form tends to grow near the centre of the lung, and accounts for approximately 25-30% of all NSCLC cases.[3]

About TECENTRIQ
TECENTRIQ is a monoclonal antibody designed to bind with a protein called PD-L1 expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, TECENTRIQ may enable the activation of T cells. TECENTRIQ has the potential to be used as a foundational combination partner with cancer immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers.

Currently, Roche has eight Phase III lung cancer studies underway, evaluating TECENTRIQ alone or in combination with other medicines.

TECENTRIQ is already approved in the European Union, United States and more than 70 countries for people with previously treated metastatic NSCLC and for certain types of untreated or previously treated metastatic urothelial carcinoma (mUC).

About Avastin (bevacizumab)
Avastin is a biologic cancer treatment approved across several types of cancers including advanced stages of breast cancer, colorectal cancer, non-small cell lung cancer, kidney cancer, ovarian cancer and cervical cancer, and recurrent glioblastoma. Avastin is approved in combination with chemotherapy for the first-line treatment of advanced NSCLC and, to-date, has helped over 500,000 patients lead longer lives. Avastin is considered a standard of care for the first-line treatment of advanced NSCLC and has been proven to significantly extend overall survival (OS). Avastin is currently approved in combination with any platinum-based chemotherapy in Europe, and with paclitaxel/carboplatin in the US, in first-line non-squamous NSCLC, based on results of the pivotal Phase III E4599 study. Avastin was the first medicine to help people with previously untreated advanced, non-squamous NSCLC live longer (OS) than one year when added to chemotherapy.

About the TECENTRIQ (atezolizumab) and Avastin (bevacizumab) combination
There is a strong scientific rationale to support combining TECENTRIQ and Avastin. The TECENTRIQ and Avastin regimen may enhance the potential of the immune system to combat a broad range of cancers, including first-line advanced NSCLC. Avastin, in addition to its established anti-angiogenic effects, may further enhance TECENTRIQ’s ability to restore anti-cancer immunity, by inhibiting VEGF-related immunosuppression, promoting T-cell tumour infiltration and enabling priming and activation of T-cell responses against tumour antigens.

Eisai and Merck Announce China National Medical Products Administration (NMPA) Approval of LENVIMA® (lenvatinib) for Treatment of Unresectable Hepatocellular Carcinoma (HCC)

On September 5, 2018 Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, "Eisai") and Merck (NYSE: MRK), known as MSD outside of the United States and Canada, reported that the China National Medical Products Administration (NMPA) approved the kinase inhibitor LENVIMA (lenvatinib) as a single agent for the treatment of patients with unresectable hepatocellular carcinoma (HCC) who have not received prior systemic therapy (Press release, Eisai, SEPT 5, 2018, View Source [SID1234529296]). In China, the application of LENVIMA was submitted in October 2017 and was designated for Priority Review by the NMPA due to LENVIMA’s significant clinical benefit compared to existing treatments, leading to approval in approximately 10 months. This approval marks the first for LENVIMA in China, where the incidence of HCC is high, and the first new systemic therapy approved for the first-line treatment of unresectable HCC in China in ten years.

"Over the past decade, there have been limited treatment options available for patients with unresectable HCC," said Dr. Takashi Owa, Vice President and Chief Medicine Creation Officer, Oncology Business Group, Eisai. "We are pleased to be able to deliver LENVIMA to HCC patients in China, and we are thankful for the collaborative efforts by regulatory and government authorities, as well as the patients and physicians who participated in the clinical studies and made this approval possible."

"Today’s milestone for LENVIMA is an important one for patients in China living with unresectable HCC, which is historically difficult to treat and has a poor prognosis," said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. "Merck remains committed to bringing new treatment advances to patients in China. The approval of LENVIMA, through our collaboration with Eisai, is the third cancer medicine in our portfolio to be approved in China this year – reinforcing the great progress being made to bring new treatment options forward for Chinese patients."

The approval was based on results from the REFLECT study (Study 304), an open-label, Phase 3 trial where LENVIMA demonstrated a treatment effect on overall survival (OS) by statistical confirmation of non-inferiority when compared with the standard of care, sorafenib, in 954 patients with previously untreated unresectable HCC; patients randomized to the LENVIMA arm did not have a statistically significant improvement in OS compared to those in the sorafenib arm. LENVIMA demonstrated statistically significant superiority and clinically meaningful improvements in progression-free survival (PFS), time to progression (TTP) and objective response rate (ORR). In a subpopulation analysis of 288 patients in the study from the greater Chinese region (mainland China, Hong Kong and Taiwan), LENVIMA demonstrated efficacy based on non-inferiority of OS compared to sorafenib, with improvements also observed in PFS, TTP and ORR. Approximately 80% of patients in the subpopulation were living with HCC resulting from chronic hepatitis B virus (HBV), which has high unmet medical need. For these patients, LENVIMA demonstrated non-inferiority based on OS compared with sorafenib, thereby demonstrating the effect of LENVIMA in patients with HCC resulting from HBV.

In the China package insert, the five most common adverse reactions observed in patients treated with LENVIMA were hypertension (45%), fatigue (44%), diarrhea (39%), decreased appetite (34%) and decreased weight (31%), which is consistent with the known side-effect profile of LENVIMA.

Liver cancer is the second leading cause of cancer-related deaths and is estimated to be responsible for approximately 750,000 deaths per year globally. Additionally, approximately 780,000 cases are newly diagnosed each year, about 80% of which occur in Asian regions. Specifically, in China, there are approximately 395,000 new cases and 380,000 deaths per year, accounting for approximately 50% of cases worldwide. HCC accounts for 85% to 90% of primary liver cancer cases. Unresectable HCC, for which treatment options are limited, is extremely difficult to treat, and the development of new treatments is necessary.

Since the initial launch, more than 10,000 patients have been treated with LENVIMA. Today, LENVIMA is approved as a treatment for refractory thyroid cancer in over 50 countries including the United States, Japan, in Europe and Asia, and as combination with everolimus as a second-line treatment for renal cell carcinoma (RCC) in over 45 countries including the United States and in Europe. For HCC, LENVIMA was approved for use in Japan in March 2018, and in the United States and Europe in August 2018. In Japan, approximately 3,000 HCC patients have been treated with LENVIMA since approval of this indication.

About the REFLECT Trial (Study 304)

REFLECT was a large (n=954) Phase 3, randomized, multicenter, open-label trial conducted by Eisai to compare the efficacy and safety of LENVIMA versus sorafenib as a first-line systemic treatment in patients with unresectable HCC. Patients at 154 trial sites in 20 countries were randomized to receive LENVIMA 12 mg or 8 mg once a day depending on body weight (≥60 kg or <60 kg, respectively) (n=478) or sorafenib 400 mg twice a day (n=476). Treatment was continued until disease progression or unacceptable toxicity. The primary endpoint of this study was OS, tested first for non-inferiority to sorafenib, then for superiority. The key secondary efficacy endpoints of this study included PFS, TTP and ORR, tested for superiority to sorafenib.

In the China package insert, REFLECT showed that LENVIMA achieved the primary endpoint, demonstrating a treatment effect on OS by statistical confirmation of non-inferiority to sorafenib. Patients treated with LENVIMA experienced a median OS of 13.6 months compared to 12.3 months with sorafenib (Hazard Ratio [HR]: 0.92; 95% Confidence Interval [CI]: 0.79-1.06). Patients randomized to the LENVIMA arm did not have a statistically significant improvement in OS compared to those in the sorafenib arm. In addition, LENVIMA showed statistically significant superiority and clinically meaningful improvements in the secondary efficacy endpoints of PFS, TTP and ORR, as confirmed by a blinded independent imaging review:

Median PFS was doubled with LENVIMA compared to sorafenib: 7.3 months versus 3.6 months (HR: 0.64; 95% CI: 0.55–0.75; p<0.00001) per blinded independent imaging review based on mRECIST criteria.
Median TTP was doubled with LENVIMA compared to sorafenib: 7.4 months versus 3.7 months (HR: 0.60; 95% CI: 0.51–0.71; p<0.00001) per blinded independent imaging review based on mRECIST criteria.
LENVIMA showed nearly 3.5 times the ORR of sorafenib: 40.6% (95% CI: 36.2-45.0) versus 12.4% (95% CI: 9.4-15.4) per blinded independent imaging review based on mRECIST criteria (odds ratio 5.01; 95% CI: 3.59-7.01; p<0.00001).
About the Subpopulation Analysis of Patients from the Greater Chinese Region

The results of subpopulation analysis of patients from the greater Chinese region were based on 288 patients out of the 954 HCC patients who participated in the REFLECT study. In this subpopulation analysis, median OS was 15.0 months for LENVIMA versus 10.2 months for sorafenib (HR: 0.73; 95% CI: 0.55-0.96; nominal p=0.02620). Independent imaging review based on mRECIST criteria revealed the following results: PFS (LENVIMA 8.4 months versus sorafenib 3.6 months in median [HR: 0.47; 95% CI: 0.35-0.64; nominal p<0.00001]), TTP (LENVIMA 9.2 months versus sorafenib 3.6 months in median [HR: 0.45; 95% CI: 0.33-0.62; nominal p<0.00001]) and ORR (LENVIMA 43.8% versus sorafenib 13.2% [odds ratio 5.14; 95% CI: 2.84-9.31; nominal p<0.00001]).

Additionally, of the 288 patients in the subpopulation, approximately 80% (n=242) were living with HCC resulting from HBV. An analysis of these patients revealed the following results for OS: LENVIMA (n=123) 14.9 months versus sorafenib (n=119) 9.9 months in median (HR: 0.72; 95% CI: 0.53-0.97).

About Unresectable Hepatocellular Carcinoma (HCC)

Liver cancer is the second leading cause of cancer-related deaths and is estimated to be responsible for 750,000 deaths per year globally. Additionally, 780,000 cases are newly diagnosed each year. There is a large regional difference, with about 80% of new cases occurring in Asian regions, including China and Japan. HCC accounts for 85% to 90% of primary liver cancer cases. HCC is associated with chronic liver disease, in particular cirrhosis. Major causes of cirrhosis include hepatitis B virus and hepatitis C virus. However, according to a recent investigation, non-B/non-C HCC is on the rise. Surgery is the first option for treatment, but for patients with unresectable HCC who are not amenable for potentially curative therapeutic interventions, which include liver transplant, surgical resection and tumor ablation (typically radiofrequency ablation or cryotherapy), or who are not suitable for transarterial chemoembolization (TACE), treatment options are limited and the prognosis is very poor.

About LENVIMA (lenvatinib) capsules 10 mg and 4 mg

LENVIMA (lenvatinib) is a kinase inhibitor that is indicated in the U.S.:

For the treatment of patients with locally recurrent or metastatic, progressive radioactive iodine-refractory differentiated thyroid cancer (DTC)
In combination with everolimus, for the treatment of patients with advanced renal cell carcinoma (RCC) following one prior anti-angiogenic therapy
For the first-line treatment of patients with unresectable hepatocellular carcinoma (HCC)
LENVIMA, discovered and developed by Eisai, is a 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. Lenvatinib also exhibited antiproliferative activity in hepatocellular carcinoma cell lines dependent on activated FGFR signaling with a concurrent inhibition of FGF-receptor substrate 2α (FRS2α) phosphorylation.

Important Safety Information in the U.S.

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%. Fistulas and gastrointestinal perforations have also been reported in other lenvatinib clinical trials and in post-marketing experience. Pneumothorax has been reported with and without clear evidence of a bronchopleural fistula. Some reports of gastrointestinal perforation, fistula, and pneumothorax occurred in association with tumor regression or necrosis. In most cases of fistula formation or gastrointestinal perforation, risk factors such as prior surgery or radiotherapy were present.

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.

Wound Healing Complications. Wound healing complications, including fistula formation and wound dehiscence, can occur with LENVIMA. Withhold for at least 6 days prior to scheduled surgery. Resume after surgery based on clinical judgment of adequate wound healing. Permanently discontinue in patients with wound healing complications.

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.

Use in Specific Populations

Because of the potential for serious adverse reactions in breastfed infants, advise women to discontinue breastfeeding during treatment and for at least 1 week after last dose. LENVIMA may impair fertility in males and females of reproductive potential.

No dose adjustment is recommended for patients with mild (CLcr 60-89 mL/min) or moderate (CLcr 30-59 mL/min) renal impairment. LENVIMA concentrations may increase in patients with DTC or RCC and severe (CLcr 15-29 mL/min) renal impairment. Reduce the dose for patients with RCC or DTC and severe renal impairment. There is no recommended dose for patients with HCC and severe renal impairment. LENVIMA has not been studied in patients with end stage renal disease.

No dose adjustment is recommended for patients with HCC and mild hepatic impairment (Child-Pugh A). There is no recommended dose for patients with HCC with moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment.

No dose adjustment is recommended for patients with DTC or RCC and mild or moderate hepatic impairment. LENVIMA concentrations may increase in patients with DTC or RCC and severe hepatic impairment. Reduce the dose for patients with DTC or RCC and severe hepatic impairment.
