The CRL results from findings pertaining to an inspection of a third-party manufacturing facility. The CRL did not identify any issues with the efficacy or safety data submitted.

Patritumab deruxtecan is a specifically engineered potential first-in-class HER3 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed by Daiichi Sankyo and Merck.

"We will work closely with the FDA and the third-party manufacturer to address the feedback as quickly as possible in order to bring the first HER3 directed medicine to patients with previously-treated EGFR-mutated non-small cell lung cancer." said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo. "We remain confident in the ability to develop this medicine to its full potential."

"Patients with previously treated EGFR-mutated non-small cell lung cancer often experience recurrence and have limited treatment options." said Marjorie Green, MD, Senior Vice President and Head of Oncology, Global Clinical Development, Merck Research Laboratories. We are committed to working with Daichi Sankyo and the FDA to prioritize making patritumab deruxtecan available to these patients in need."

The BLA is based on the primary results from the HERTHENA-Lung01 pivotal phase 2 trial that were presented at the IASLC 2023 World Conference on Lung Cancer (#WCLC23) and simultaneously published in the Journal of Clinical Oncology.

In HERTHENA-Lung01, patritumab deruxtecan was studied in 225 patients with EGFR-mutated locally advanced or metastatic NSCLC following disease progression with an EGFR TKI and platinum-based chemotherapy, which demonstrated an objective response rate (ORR) of 29.8% (95% CI: 23.9-36.2), including one complete response and 66 partial responses. The median duration of response (DoR) was 6.4 months (95% CI: 4.9-7.8).

The safety profile of patritumab deruxtecan observed in HERTHENA-Lung01 was consistent with previous phase 1 clinical trials in NSCLC with a treatment discontinuation rate of 7.1% due to treatment-emergent adverse events (TEAEs). Grade 3 or higher TEAEs occurred in 64.9% of patients. The most common (≥5%) grade 3 or higher TEAEs were thrombocytopenia (21%), neutropenia (19%), anemia (14%), leukopenia (10%), fatigue (6%), hypokalemia (5%) and asthenia (5%). Twelve patients (5.3%) had confirmed treatment-related interstitial lung disease (ILD) as determined by an independent adjudication committee. One grade 5 ILD event was observed.

About HERTHENA-Lung01
HERTHENA-Lung01 is a global, multicenter, open-label, two-arm phase 2 trial evaluating the safety and efficacy of patritumab deruxtecan in patients with EGFR-mutated locally advanced or metastatic NSCLC following disease progression with an EGFR TKI and platinum-based chemotherapy. Patients were randomized 1:1 to receive 5.6 mg/kg (n=225) or an uptitration regimen (n=50). The uptitration arm was discontinued as the dose of 5.6 mg/kg of patritumab deruxtecan was selected following a risk-benefit analysis conducted from the phase 1 trial assessing the doses in a similar patient population.

The primary endpoint of HERTHENA-Lung01 was ORR as assessed by blinded independent central review (BICR). Secondary endpoints included DoR, progression-free survival, disease control rate, and time to response – all assessed by both BICR and investigator assessment – as well as investigator-assessed ORR, overall survival, safety and tolerability.

HERTHENA-Lung01 enrolled patients in Asia, Europe, North America and Oceania. For more information about the trial, visit ClinicalTrials.gov.

About EGFR-mutated non-small cell lung cancer
Approximately 226,000 lung cancer cases were diagnosed in the U.S. in 2022. Lung cancer is the third most common cancer and the leading cause of cancer-related deaths in the U.S. NSCLC accounts for approximately 81% of all lung cancers in the U.S., with 52% having distant spread at diagnosis. EGFR mutations occur in approximately 1 in 5 patients with NSCLC in Western populations.

About HER3
HER3 is a member of the EGFR family of receptor tyrosine kinases. It is estimated that about 83% of primary NSCLC tumors and 90% of advanced EGFR-mutated tumors express HER3 after prior EGFR TKI treatment. HER3 is associated with poor treatment outcomes, including shorter relapse-free survival and significantly reduced survival. There is currently no HER3 directed therapy approved for the treatment of any cancer.

About patritumab deruxtecan
Patritumab deruxtecan (HER3-DXd) is an investigational HER3 directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC Technology, patritumab deruxtecan is composed of a fully human anti-HER3 IgG1 monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.

Patritumab deruxtecan was granted Breakthrough Therapy Designation by the U.S. Food and Drug Administration in December 2021 for the treatment of patients with EGFR-mutated locally advanced or metastatic NSCLC with disease progression on or after treatment with a third-generation TKI and platinum-based therapies.

Patritumab deruxtecan is currently being evaluated as both a monotherapy and in combination with other therapies in a global development program, which includes HERTHENA-Lung02, a phase 3 trial evaluating the efficacy and safety of patritumab deruxtecan versus platinum-based chemotherapy in patients with EGFR-mutated locally advanced or metastatic NSCLC following disease progression on or after treatment with a third-generation EGFR TKI; HERTHENA-Lung01, a phase 2 trial in metastatic or locally advanced NSCLC with an activating EGFR mutation previously treated with at least one EGFR TKI and one platinum-based chemotherapy-containing regimen; HERTHENA-PanTumor01, a phase 2 trial in locally advanced or metastatic solid tumors, including melanoma, gastric and head and neck cancer, among other types of cancer, previously treated with at least one prior systemic therapy; a phase 1 trial in combination with osimertinib in EGFR-mutated locally advanced or metastatic NSCLC; and a phase 1 trial in previously treated patients with advanced NSCLC. A phase 1/2 trial in HER3 expressing metastatic breast cancer also has been completed.

About the Daiichi Sankyo and Merck collaboration
Daiichi Sankyo and Merck entered into a global collaboration in October 2023 to jointly develop and commercialize patritumab deruxtecan (HER3-DXd), ifinatamab deruxtecan (I-DXd) and raludotatug deruxtecan (R-DXd), except in Japan where Daiichi Sankyo will maintain exclusive rights. Daiichi Sankyo will be solely responsible for manufacturing and supply.

About the DXd ADC portfolio of Daiichi Sankyo
The DXd ADC portfolio of Daiichi Sankyo currently consists of six ADCs in clinical development across multiple types of cancer. ENHERTU, a HER2 directed ADC, and datopotamab deruxtecan (Dato-DXd), a TROP2 directed ADC, are being jointly developed and commercialized globally with AstraZeneca. Patritumab deruxtecan (HER3-DXd), a HER3 directed ADC, ifinatamab deruxtecan (I-DXd), a B7-H3 directed ADC, and raludotatug deruxtecan (R-DXd), a CDH6 directed ADC, are being jointly developed and commercialized globally with Merck. DS-3939, a TA-MUC1 directed ADC, is being developed by Daiichi Sankyo.

Designed using Daiichi Sankyo’s proprietary DXd ADC Technology to target and deliver a cytotoxic payload inside cancer cells that express a specific cell surface antigen, each ADC consists of a monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.

Datopotamab deruxtecan, ifinatamab deruxtecan, patritumab deruxtecan, raludotatug deruxtecan and DS-3939 are investigational medicines that have not been approved for any indication in any country. Safety and efficacy have not been established.

The approval by China’s National Medical Products Administration (NMPA) was based on the results from the FLAURA2 Phase III trial published in The New England Journal of Medicine, and results from a prespecified exploratory subgroup analysis of efficacy and safety in Chinese patients, which was presented at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Asia Congress 2023.

In the overall trial population, Tagrisso with the addition of chemotherapy reduced the risk of disease progression or death by 38% by investigator assessment compared to Tagrisso monotherapy, which is the 1st-line global standard of care (hazard ratio [HR] 0.62; 95% confidence interval [CI] 0.49-0.79; p<0.0001). Median progression-free survival (PFS) was 25.5 months for patients treated with Tagrisso plus chemotherapy, an 8.8-month improvement versus Tagrisso monotherapy (16.7 months).

PFS results by blinded independent central review (BICR) in the overall trial population were consistent with results by investigator assessment, showing 29.4 months median PFS with Tagrisso plus chemotherapy, a 9.5-month improvement over Tagrisso monotherapy (19.9 months) (HR 0.62; 95% CI 0.48-0.80; p=0.0002).

While the overall survival (OS) remained immature at the second interim analysis (41% maturity), an encouraging trend towards an OS benefit was observed with Tagrisso plus chemotherapy versus Tagrisso alone (HR 0.75; 95% CI 0.57-0.97). The trial continues to assess OS as a key secondary endpoint.

Efficacy results from the China cohort of FLAURA2 were broadly consistent with the overall trial. By investigator assessment, Tagrisso with the addition of chemotherapy reduced the risk of disease progression or death by 44% compared to Tagrisso monotherapy (HR 0.56; 95% CI 0.34-0.92). Median PFS was 27.4 months for patients treated with Tagrisso plus chemotherapy, a 5.1-month improvement versus Tagrisso monotherapy (22.3 months).

PFS results in the China cohort by BICR were consistent with the results by investigator assessment, showing 33.2 months median PFS with Tagrisso plus chemotherapy, an 11.2-month improvement over Tagrisso monotherapy (22.0 months) (HR 0.58; 95% CI 0.34-1.01).

A trend towards an OS benefit was also observed in the China cohort for Tagrisso plus chemotherapy versus Tagrisso alone (HR 0.97; 95% CI 0.45-2.06).

Each year in China, there are over one million people diagnosed with lung cancer, accounting for more than a third of the world’s lung cancer patients.1,2 Among those with NSCLC, the most common form of lung cancer, approximately 40% of patients in China have tumours with an EGFR mutation.3 Additionally, the majority of patients with NSCLC are diagnosed with advanced disease.4

Professor Ying Cheng, MD, Director of Jilin Lung Cancer Diagnosis and Treatment Centre, and principal investigator in China said: "The approval of osimertinib with the addition of chemotherapy in China is critical for the treatment of the largest population of patients with EGFR-mutated lung cancer worldwide. These patients will now have a choice of two highly effective osimertinib-based options for 1st-line treatment, allowing physicians to tailor their approach to their patients. This is especially important for those with a poorer prognosis, such as cancer that has spread to the brain or those who have L858R mutations."

Dave Fredrickson, Executive Vice President, Oncology Business Unit, AstraZeneca, said: "Tagrisso with the addition of chemotherapy in FLAURA2 has not only shown unprecedented progression-free survival in the overall trial population, but also among Chinese patients, reducing the risk of disease progression by nearly half. This approval reinforces Tagrisso as a backbone therapy in EGFR-mutated lung cancer and acknowledges its important role, as monotherapy or with chemotherapy, in addressing the high prevalence of this disease in Asian countries and China, specifically."

The safety profile of Tagrisso with the addition of chemotherapy was generally manageable and consistent with the established profiles of the individual medicines. Adverse event (AE) rates were higher in the Tagrisso plus chemotherapy arm, driven by well-characterised chemotherapy-related AEs. Discontinuation rates of Tagrisso due to AEs were 11% for Tagrisso plus chemotherapy and 6% for monotherapy.

Tagrisso is approved as monotherapy in more than 100 countries including in the US, EU, China and Japan. Approved indications include for 1st-line treatment of patients with locally advanced or metastatic EGFRm NSCLC, locally advanced or metastatic EGFR T790M mutation-positive NSCLC, and adjuvant treatment of early-stage EGFRm NSCLC. In addition to this new approval in China, Tagrisso with the addition of chemotherapy is also approved in the US and several other countries for 1st-line treatment of patients with locally advanced or metastatic EGFRm NSCLC.

Notes

Lung cancer
Lung cancer is the leading cause of cancer death among both men and women, accounting for about one-fifth of all cancer deaths.5 Lung cancer is broadly split into NSCLC and small cell lung cancer.6 Each year there are an estimated 2.4 million people diagnosed with lung cancer globally, with 80-85% of patients diagnosed with NSCLC, the most common form of lung cancer.5-8

Approximately 10-15% of NSCLC patients in the US and Europe, and 30-40% of patients in Asia have EGFRm NSCLC.9-11 Patients with EGFRm NSCLC are particularly sensitive to treatment with an EGFR-tyrosine kinase inhibitor (EGFR-TKI) which blocks the cell-signalling pathways that drive the growth of tumour cells.12

FLAURA2
FLAURA2 is a randomised, open-label, multi-centre, global Phase III trial in the 1st-line treatment of patients with locally advanced (Stage IIIB-IIIC) or metastatic (Stage IV) EGFRm NSCLC. Patients were treated with Tagrisso 80mg once-daily oral tablets with the addition of chemotherapy (pemetrexed (500mg/m2) plus cisplatin (75mg/m2) or carboplatin (AUC5)) every three weeks for four cycles, followed by Tagrisso with pemetrexed maintenance every three weeks.

The trial enrolled 557 patients in more than 150 centres across more than 20 countries, including in the US, Europe, South America and Asia. The primary endpoint is PFS. The trial is ongoing and will continue to assess the secondary endpoint of OS.

Tagrisso
Tagrisso (osimertinib) is a third-generation, irreversible EGFR-TKI with proven clinical activity in NSCLC, including against central nervous system (CNS) metastases. Tagrisso (40mg and 80mg once-daily oral tablets) has been used to treat nearly 800,000 patients across its indications worldwide and AstraZeneca continues to explore Tagrisso as a treatment for patients across multiple stages of EGFRm NSCLC.

There is an extensive body of evidence supporting the use of Tagrisso in EGFRm NSCLC. Tagrisso is the only targeted therapy to improve patient outcomes in early-stage disease in the ADAURA Phase III trial , locally advanced stages in the LAURA Phase III trial and late-stage disease in the FLAURA Phase III trial and FLAURA2 Phase III trial.

As part of AstraZeneca’s ongoing commitment to treating patients as early as possible in lung cancer, Tagrisso is also being investigated in the neoadjuvant setting in the NeoADAURA Phase III trial with results expected later this year and in the early-stage adjuvant resectable setting in the ADAURA2 Phase III trial.

The Company is also researching ways to address tumour mechanisms of resistance through the SAVANNAH and ORCHARD Phase II trials, and the SAFFRON Phase III trial, which test Tagrisso plus savolitinib, an oral, potent and highly selective MET TKI, as well as other potential new medicines.

On June 25, 2024 Carisma Therapeutics Inc. (Nasdaq: CARM) ("Carisma" or the "Company"), a clinical stage biopharmaceutical company focused on discovering and developing innovative immunotherapies, reported that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for CT-0525, an ex vivo gene-modified autologous chimeric antigen receptor-monocyte (CAR-Monocyte) cellular therapy intended to treat solid tumors that overexpress human epidermal growth factor receptor 2 (HER2) (Press release, Carisma Therapeutics, JUN 25, 2024, View Source [SID1234644539]).

The FDA’s Fast Track program is aimed to facilitate the development, and expedite the review, of novel potential therapies that are designed to treat serious conditions and have the potential to address significant unmet medical need.

"Receiving Fast Track designation for CT-0525 from the FDA marks a significant milestone for Carisma, highlighting the FDA’s recognition of the serious and life-threatening nature of these malignancies and the potential of CT-0525 to meet this critical medical need," said Eugene P. Kennedy, M.D., Chief Medical Officer of Carisma. "We are committed to working closely with the FDA to accelerate the development of CT-0525. Currently, we are enrolling patients in the Phase 1 clinical trial and remain on track to report initial clinical data by the end of 2024."

The Phase 1 clinical trial for CT-0525 is an open-label study designed to assess the safety, tolerability, and manufacturing feasibility of CT-0525. This trial will enroll participants with locally advanced (unresectable) or metastatic solid tumors overexpressing HER2 whose disease has progressed on standard approved therapies. The initial study design will consist of two dose escalation cohorts. Further details of the trial can be found at www.clinicaltrials.gov under NCT identifier: NCT06254807.

About CT-0525

CT-0525 is a first-in-class, ex vivo gene-modified autologous chimeric antigen receptor-monocyte (CAR-Monocyte) cellular therapy intended to treat solid tumors that overexpress human epidermal growth factor receptor 2 (HER2). It is being studied in a multi-center, open label, Phase 1 clinical trial for patients with advanced/metastatic HER2-overexpressing solid tumors that have progressed on available therapies. The CAR-Monocyte approach has the potential to address some of the challenges of treating solid tumors with cell therapies, including tumor infiltration, immunosuppression within the tumor microenvironment, and antigen heterogeneity. CT-0525 has the potential to enable significant dose escalation, enhance tumor infiltration, increase persistence, and reduce manufacturing time compared to macrophage therapy.
