On November 14, 2022 AstraZeneca and Daiichi Sankyo reported that it’s Enhertu (trastuzumab deruxtecan) has been recommended for approval in the European Union (EU) as monotherapy for the treatment of adult patients with advanced HER2-positive gastric or gastroesophageal junction (GEJ) adenocarcinoma who have received a prior trastuzumab-based regimen (Press release, AstraZeneca, NOV 14, 2022, View Source [SID1234623927]).

Enhertu is a specifically engineered HER2-directed antibody drug conjugate (ADC) being jointly developed and commercialised by AstraZeneca and Daiichi Sankyo.

The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency based its positive opinion on results from the DESTINY-Gastric02 and the DESTINY-Gastric01 Phase II trials.

In DESTINY-Gastric02, conducted in patients from North America and Europe, updated results showed treatment with Enhertu resulted in a confirmed objective response rate (ORR) of 41.8% as assessed by independent central review (ICR). Median duration of response (DoR) was 8.1 months and median overall survival (OS) was 12.1 months. Primary results from the DESTINY-Gastric02 Phase II trial were presented at the 2021 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress, with the updated data presented at ESMO (Free ESMO Whitepaper) 2022.1

In DESTINY-Gastric01, conducted in patients from Japan and South Korea, updated results showed treatment with Enhertu resulted in an ORR of 51.3% versus 14.3% with chemotherapy (irinotecan or paclitaxel). Patients treated with Enhertu had a 40% reduction in the risk of death versus patients treated with chemotherapy (based on a hazard ratio of 0.60; 95% confidence interval: 0.42-0.86, p=0.01) with a median OS of 12.5 months versus 8.9 months. Additionally, confirmed ORR, a major efficacy outcome, was 42.0% with Enhertu versus 12.5% with chemotherapy as assessed by ICR. The primary analysis was published in The New England Journal of Medicine,2 with the updated data presented at the 2021 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting.

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: "Gastric cancer is usually diagnosed in the advanced stage in many European countries and patients face high mortality rates. If approved, Enhertu would be the first HER2-directed medicine for patients with advanced gastric cancer in the European Union in more than a decade."

Ken Takeshita, Global Head, Oncology R&D, Daiichi Sankyo, Inc, said: "Enhertu is the first HER2-directed medicine to demonstrate a significant improvement in overall survival compared to chemotherapy in patients with gastric cancer following initial treatment with a HER2-directed medicine in the advanced or metastatic setting. The CHMP opinion recognises the high unmet need in this patient population and brings us one step closer to bringing this medicine to patients with gastric cancer in Europe."

In both trials, the safety profiles observed in patients treated with Enhertu were consistent with those seen in other trials of Enhertu with no new safety signals identified.

Enhertu is approved in the US and several other countries for locally advanced or metastatic HER2-positive gastric cancer.

Notes

HER2-positive gastric cancer
Gastric (stomach) cancer is the fifth most common cancer worldwide and the fourth highest leading cause of cancer mortality, with a five-year global survival rate of 5% to 10% for advanced or metastatic disease.3-5 Approximately one million new patients were diagnosed with gastric cancer in 2020, with 768,000 deaths reported globally.6 In Europe, approximately 136,000 cases of gastric cancer are diagnosed annually, and Eastern Europe has the second highest incidence of gastric cancer worldwide after Eastern Asia.5-6 Gastric cancer is the sixth leading cause of cancer death in Europe and is typically diagnosed in the advanced stage. Even when diagnosed in earlier stages of the disease, the survival rate remains modest.5-7

Approximately one in five gastric cancers are HER2-positive.8,9 HER2 is a tyrosine kinase receptor growth promoting protein expressed on the surface of many types of tumours including breast, gastric, lung and colorectal cancers.8 HER2 overexpression may be associated with a specific HER2 gene alteration known as HER2 amplification.9

Recommended first-line treatment for HER2-positive advanced or metastatic gastric cancer is combination chemotherapy plus trastuzumab, an anti-HER2 medicine, which has been shown to improve survival outcomes when added to chemotherapy.10 For patients with metastatic gastric cancer that progresses following initial treatment with a trastuzumab-based regimen, treatment options are limited, and in many regions in the world there are no additional HER2 directed medicines available.2,11,12

DESTINY-Gastric02
DESTINY-Gastric02 is an open-label, single-arm Phase II trial in Western patients evaluating the efficacy and safety of Enhertu (6.4mg/kg) in patients with HER2-positive metastatic and/or unresectable gastric or GEJ adenocarcinoma with disease progression on or after a trastuzumab-containing regimen.

The primary endpoint of DESTINY-Gastric02 is confirmed ORR based on ICR. Secondary endpoints include progression-free survival (PFS), OS, DoR and safety.

DESTINY-Gastric02 enrolled 79 patients at multiple sites in North America and Europe. For more information about the trial, visit ClinicalTrials.gov.

DESTINY-Gastric01
DESTINY-Gastric01 is a randomised, open-label Phase II trial evaluating the efficacy and safety of Enhertu (6.4mg/kg) in patients from Japan and South Korea with primarily HER2-positive (defined as immunohistochemistry [IHC] 3+ or IHC 2+/in-situ hybridisation [ISH]+) advanced gastric cancer or GEJ adenocarcinoma whose tumours have progressed on two or more prior treatment regimens including fluoropyrimidine (5-FU), platinum chemotherapy and trastuzumab. Patients were randomised 2:1 to receive Enhertu or physician’s choice of chemotherapy (paclitaxel or irinotecan monotherapy).

The primary endpoint of DESTINY-Gastric01 is ORR. Secondary endpoints include OS, PFS, DoR, disease control rate and time to treatment failure, as well as pharmacokinetic and safety endpoints.

DESTINY-Gastric01 enrolled 187 patients at multiple sites in Japan and South Korea. For more information about the trial, visit ClinicalTrials.gov.

Enhertu
Enhertu is a HER2-directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC technology, Enhertu is the lead ADC in the oncology portfolio of Daiichi Sankyo and the most advanced programme in AstraZeneca’s ADC scientific platform. Enhertu consists of a HER2 monoclonal antibody attached to a topoisomerase I inhibitor payload, an exatecan derivative, via a stable tetrapeptide-based cleavable linker.

Enhertu (5.4mg/kg) is approved in more than 35 countries for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received a (or one or more) prior anti-HER2-based regimen either in the metastatic setting, or in the neoadjuvant or adjuvant setting and have developed disease recurrence during or within six months of completing therapy based on the results from the DESTINY-Breast03 trial.

Enhertu (5.4mg/kg) is approved in several countries for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens based on the results from the DESTINY-Breast01 trial.

Enhertu (5.4mg/kg) is approved in Brazil and the US for the treatment of adult patients with unresectable or metastatic HER2-low (IHC 1+ or IHC 2+/ISH-) breast cancer who have received a prior chemotherapy in the metastatic setting or developed disease recurrence during or within six months of completing adjuvant chemotherapy based on the results from the DESTINY-Breast04 trial.

Enhertu (5.4mg/kg) is approved under accelerated approval in the US for the treatment of adult patients with unresectable or metastatic non-small cell lung cancer whose tumours have activating HER2 (ERBB2) mutations, as detected by an FDA-approved test, and who have received a prior systemic therapy, based on the results of the DESTINY-Lung02 trial. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Enhertu (6.4mg/kg) is approved in several countries for the treatment of adult patients with locally advanced or metastatic HER2-positive gastric or GEJ who have received a prior trastuzumab-based regimen based on the results from the DESTINY-Gastric01 trial.

Enhertu development programme
A comprehensive development programme is underway globally, evaluating the efficacy and safety of Enhertu monotherapy across multiple HER2-targetable cancers, including breast, gastric, lung and colorectal cancers. Trials in combination with other anticancer treatments, such as immunotherapy, are also underway.

Regulatory applications for Enhertu in breast and gastric cancer are currently under review in several other countries based on the DESTINY-Breast01, DESTINY-Breast03, DESTINY-Breast04, DESTINY-Gastric01 and DESTINY-Gastric02 trials, respectively.

The trial was positive, having met one of the primary endpoints of statistically significant improvement in progression-free survival ("PFS"), which is clinically meaningful. The other primary endpoint of overall survival ("OS") was not statistically significant per the pre-specified statistical plan, although there was an improvement in median OS. Fruquintinib also demonstrated a statistically significant improvement in secondary endpoints including objective response rate (ORR), disease control rate (DCR), and improved duration of response (DoR). The safety profile of fruquintinib in FRUTIGA was consistent with previously reported studies.

Full detailed results are subject to ongoing analysis and are expected to be disclosed at an upcoming scientific meeting. These results as well as further analyses will be shared with the China National Medical Products Administration ("NMPA").

"The combination of fruquintinib and paclitaxel demonstrated significant clinical benefits for these patients in controlling this disease. Our team will continue to analyze the data and discuss these findings with the NMPA for possible NDA filing," said Dr Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED.

Professor Rui-Hua Xu, MD, President of the Sun Yat-Sen University Cancer Center, who served as the FRUTIGA lead principal investigator and Steering Committee Chairman, said: "By meeting the primary endpoint of PFS, fruquintinib demonstrated consistent efficacy and safety in gastric cancer indication in addition to its approved colorectal cancer indication. I am extremely excited that fruquintinib may provide a potential new oral treatment option for second line gastric cancer patients based on the FRUTIGA trial."

HUTCHMED retains all commercial rights to fruquintinib outside of China. In China, where fruquintinib is marketed under the brand name ELUNATE, HUTCHMED is partnered with Eli Lilly and Company. HUTCHMED is responsible for development and execution of all on-the-ground medical detailing, promotion and local and regional marketing. Fruquintinib is not approved for use outside of China.

About FRUTIGA and Gastric Cancer

The safety and efficacy of fruquintinib for the following investigational uses have not been established and there is no guarantee that it will receive health authority approval or become commercially available in any country for the uses being investigated:

The FRUTIGA study is a randomized, double-blind, Phase III study in China to evaluate fruquintinib combined with paclitaxel compared with paclitaxel monotherapy, for second-line treatment of advanced gastric cancer or GEJ adenocarcinoma. The trial enrolled patients who did not respond to first-line standard chemotherapy. Patients were randomized at a 1:1 ratio and stratified according to factors such as stomach vs. GEJ tumor type and performance status. Additional details about this study can be found at clinicaltrials.gov, using identifier NCT03223376.

Gastric cancer is the fourth leading cause of cancer death worldwide. Over one million new cases of gastric cancer and approximately 769,000 deaths were estimated in 2020 worldwide, with the highest incidence rates in several Eastern Asian countries. In 2020, there were 478,500 new gastric cancer cases and 331,600 deaths estimated in China.1 Due to late-onset symptoms, gastric cancer is often diagnosed at an advanced stage with poor prognosis and limited treatment options.

About Fruquintinib

Fruquintinib is a highly selective and potent oral inhibitor of VEGFR-1, -2 and -3. VEGFR inhibitors play a pivotal role in blocking tumor angiogenesis. Fruquintinib was designed to improve kinase selectivity to minimize off-target toxicities, improve tolerability and provide more consistent target coverage. The generally good tolerability in patients to date, along with fruquintinib’s low potential for drug-drug interaction based on preclinical assessment, suggests that it may also be highly suitable for combinations with other anti-cancer therapies.

About Fruquintinib Approval in China

Metastatic colorectal cancer ("CRC") in China: Fruquintinib was approved for marketing by the NMPA in September 2018 and commercially launched in China in November 2018 under the brand name ELUNATE. It has been included in the China National Reimbursement Drug List (NRDL) since January 2020. ELUNATE is indicated for the treatment of patients with metastatic CRC who have been previously treated with fluoropyrimidine, oxaliplatin and irinotecan, including those who have previously received anti-VEGF therapy and/or anti-EGFR therapy (RAS wild type). Results of the FRESCO study2, a Phase III pivotal registration trial of fruquintinib in 416 patients with metastatic CRC in China, were published in The Journal of the American Medical Association, JAMA, in June 2018 (NCT02314819).

About Other Fruquintinib Development

Metastatic CRC in the U.S., Europe, Japan and Australia: The FRESCO-2 study is a multi-regional clinical trial ("MRCT") conducted in the U.S., Europe, Japan and Australia that investigated fruquintinib plus best supportive care ("BSC") vs placebo plus BSC in patients with advanced, refractory metastatic CRC. The results were recently presented at the European Society for Medical Oncology Congress 2022. The MRCT FRESCO-2 study demonstrated that treatment with fruquintinib resulted in a statistically significant and clinically meaningful increase in the primary OS endpoint and key secondary PFS endpoint compared to treatment with placebo. The safety profile of fruquintinib in FRESCO-2 was consistent with previously reported fruquintinib studies. We plan to complete new drug application filings in the U.S., Europe and Japan in 2023 (NCT04322539). The U.S. FDA granted Fast Track Designation for the development of fruquintinib for the treatment of patients with metastatic CRC in June 2020.

Immunotherapy combinations: HUTCHMED has entered into collaboration agreements to evaluate the safety, tolerability and efficacy of fruquintinib in combination with PD-1 monoclonal antibodies, including with tislelizumab (developed by BeiGene, Ltd) and sintilimab (developed by Innovent Biologics, Inc.).

●Metastatic breast, endometrial, and colorectal cancers in the U.S.: HUTCHMED initiated this open-label, multi-center, non-randomized, Phase Ib/II study in the U.S. to investigate if the addition of fruquintinib can potentially induce activity to immune checkpoint inhibitor therapy in advanced, refractory triple negative breast cancer ("TNBC"), endometrial cancer, and CRC (NCT04577963). Safety and preliminary efficacy of fruquintinib as a single agent were demonstrated in advanced solid tumors, including TNBC, in a Phase I study conducted in China (NCT01645215) and a Phase I/Ib study is ongoing in the U.S. (NCT03251378).

●Gastric, colorectal and non-small cell lung cancers ("NSCLC") in China & Korea: BeiGene, Ltd. initiated this open-label, multi-center, Phase II study to assess the safety and efficacy of fruquintinib in combination with tislelizumab in patients with advanced or metastatic, unresectable gastric cancer, CRC or NSCLC (NCT04716634).

●Endometrial cancer and other solid tumors in China: HUTCHMED initiated this open-label, multi-center, non-randomized, Phase II study to assess the safety and efficacy of fruquintinib in combination with sintilimab in patients with advanced cervical cancer, endometrial cancer, gastric cancer, hepatocellular carcinoma (HCC), NSCLC or renal cell carcinoma (RCC). Preliminary results of certain cohorts were presented at the 2021 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (ASCO) (Free ASCO Whitepaper) and the Chinese Society of Clinical Oncology Annual Meeting (CSCO). Following encouraging data in the advanced endometrial cancer cohort, it has been expanded into a single-arm registrational Phase II study of over 130 patients (NCT03903705).

About Melanocortin Receptor Agonists and Inflammation

The melanocortin receptor ("MCr") system has effects on inflammation, immune system responses, metabolism, food intake, and sexual function. There are five melanocortin receptors, MC1r through MC5r. Modulation of these receptors, through use of receptor-specific agonists, which activate receptor function, or receptor-specific antagonists, which block receptor function, can have medically significant pharmacological effects.

Many tissues and immune cells located in the eye (and other places, for example the gut and kidney) express melanocortin receptors, empowering our opportunity to directly activate natural pathways to resolve disease inflammation.

On November 14, 2022 Calliditas Therapeutics reported the European Commission issued the conditional marketing authorization for Kinpeygo, which marked the first time that any drug has achieved approval for this rare disease in EU (Press release, Calliditas Therapeutics, NOV 14, 2022, View Source [SID1234623915]). We immediately started the process of transferring the market authorization to our European partner, STADA Arzneimittel AG, in order to enable a launch in Europe as quickly as possible.

With approval and commercial efforts now ongoing in both the US and Europe, we are looking forward to the regulatory process in China, where our partner, Everest Medicines, expects to receive NDA acceptance notice from NMPA this quarter. We are excited to support Everest as they work with regulators in China, who are expected to reach a decision regarding a potential approval in the second half of next year. If Nefecon is approved, this would be the first and only approved medication for the by Everest estimated 5m biopsy-proven IgAN patients in China.

In the US, we continue to build on our early commercial success. Net sales from TARPEYO grew by 94% when compared to Q2, resulting in net sales from TARPEYO of SEK 123.4 million ($12.1m) for Q3. There is a growing number of nephrologists choosing to prescribe TARPEYO, with 166 new prescribers added in Q3, bringing total unique prescribers to 480 at the end of the quarter. We continue to see a continuous build of interest which mirrors the natural cadence of nephrology visits, which aligns with our expectations regarding this fairly silent, progressive disease. We expect to achieve net sales from TARPEYO for the year of between $35 – 40m, which aligns with our internal plans for 2022. We also expect to see significant continued growth in 2023 as nephrologists become more familiar with the clinical data, access becomes more streamlined, and as topline data from the Part B of the NefIgArd trial becomes available.

We were delighted to be able to have the Part A data published in Kidney International in October, 2022, as regulators also posted their review assessments. This data set, showing increasing reduction of proteinuria across the entire patient population during the 9 months on drug as well as significant continued reduction of proteinuria across the entire study population in the following 3 months when no drug was administered, showing a highly differentiated profile. The significance of this data was further confirmed by countless interactions at the American Society of Nephrology (ASN) Kidney Week in early November, where we had the opportunity to engage not only with KOLs but with the broader nephrology community treating IgAN patients."

Significant events during Q3 2022, in summary
In July 2022, Calliditas announced that the European Commission (EC) granted conditional marketing authorization for Kinpeygo for the treatment of IgA nephropathy (IgAN) in adults at risk of rapid disease progression with a urine protein-to-creatinine ratio (UPCR) ≥1.5 g/gram.
