On September 20, 2024 AbbVie (NYSE: ABBV) reported that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending the marketing authorization of mirvetuximab soravtansine (ELAHERE) for the treatment of adult patients with folate receptor alpha (FRα)-positive, platinum-resistant and high-grade serous epithelial ovarian, fallopian tube or primary peritoneal cancer who have received one to three prior treatment regimens (Press release, AbbVie, SEP 20, 2024, View Source [SID1234646774]). Patients with ovarian cancer are often diagnosed with late-stage disease, undergo surgery and are then primarily treated with platinum-based chemotherapy. Over time patients may become resistant to platinum-based treatment and will require another therapy. The CHMP’s opinion is supported by results of the Phase 3 MIRASOL clinical trial and the European Commission decision on this indication for mirvetuximab soravtansine is anticipated later this year.

"Following many years of development by the ImmunoGen team that is now part of AbbVie, we are hopeful to make mirvetuximab soravtansine available to eligible patients with ovarian cancer in the European Union. This positive opinion recognizes the unmet need for certain patients with platinum-resistant ovarian cancer," said Roopal Thakkar, M.D., executive vice president, research and development, chief scientific officer, AbbVie.

ELAHERE (mirvetuximab soravtansine-gynx) was granted full FDA approval in the United States in March 2024. Marketing authorization submissions for mirvetuximab soravtansine are under review in multiple other countries.

ABOUT THE PHASE 3 MIRASOL TRIAL
MIRASOL is a global Phase 3 open-label, randomized, controlled trial that enrolled 453 patients to compare the efficacy and safety of mirvetuximab soravtansine with the investigator’s choice of single-agent chemotherapy (weekly paclitaxel, pegylated liposomal doxorubicin, or topotecan) in the treatment of platinum-resistant, high-grade serous ovarian cancer whose tumors express high levels of FRα (≥75% of cells with ≥2+ staining intensity). Participants had previously received one to three lines of prior therapy. The primary endpoint was investigator-assessed progression-free survival (PFS). Key secondary endpoints included objective response rate (ORR) and overall survival (OS).

Results of the study were previously shared in June 2023. More information can be found on www.clinicaltrials.gov (NCT 04209855).

About Ovarian Cancer
Ovarian cancer is one of the leading causes of death from gynecological cancers. According to the World Ovarian Cancer Coalition, in 2022 more than 320,000 women worldwide were diagnosed with ovarian cancer. By 2050 the annual incidence will have risen to nearly half a million, an increase of 55 percent. Most patients present with late-stage disease and will typically undergo surgery followed by platinum-based chemotherapy. Unfortunately, the majority of patients eventually develop platinum-resistant disease, which is difficult to treat. In this setting, standard of care single-agent chemotherapies are associated with decreased efficacy and tolerability.

About Mirvetuximab Soravtansine
Mirvetuximab soravtansine is a first-in-class ADC comprising a folate receptor-alpha binding antibody, cleavable linker, and the maytansinoid payload DM4, a potent tubulin inhibitor designed to kill the targeted cancer cells.

Mirvetuximab soravtansine is not approved in the EU.

ELAHERE (mirvetuximab soravtansine-gynx) U.S. INDICATION and IMPORTANT SAFETY INFORMATION
ELAHERE is indicated for the treatment of adult patients with folate receptor-alpha (FRα) positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received one to three prior systemic treatment regimens. Select patients for therapy based on an FDA-approved test.

IMPORTANT SAFETY INFORMATION
WARNING: OCULAR TOXICITY

ELAHERE can cause severe ocular toxicities, including visual impairment, keratopathy, dry eye, photophobia, eye pain, and uveitis.
Conduct an ophthalmic exam including visual acuity and slit lamp exam prior to initiation of ELAHERE, every other cycle for the first 8 cycles, and as clinically indicated.
Administer prophylactic artificial tears and ophthalmic topical steroids.
Withhold ELAHERE for ocular toxicities until improvement and resume at the same or reduced dose.
Discontinue ELAHERE for Grade 4 ocular toxicities.
WARNINGS and PRECAUTIONS
Ocular Disorders
ELAHERE can cause severe ocular adverse reactions, including visual impairment, keratopathy (corneal disorders), dry eye, photophobia, eye pain, and uveitis.

Ocular adverse reactions occurred in 59% of patients with ovarian cancer treated with ELAHERE. Eleven percent (11%) of patients experienced Grade 3 ocular adverse reactions, including blurred vision, keratopathy (corneal disorders), dry eye, cataract, photophobia, and eye pain; two patients (0.3%) experienced Grade 4 events (keratopathy and cataract). The most common (≥5%) ocular adverse reactions were blurred vision (48%), keratopathy (36%), dry eye (27%), cataract (16%), photophobia (14%), and eye pain (10%).

The median time to onset for first ocular adverse reaction was 5.1 weeks (range: 0.1 to 68.6). Of the patients who experienced ocular events, 53% had complete resolution; 38% had partial improvement (defined as a decrease in severity by one or more grades from the worst grade at last follow up). Ocular adverse reactions led to permanent discontinuation of ELAHERE in 1% of patients.

Premedication and use of lubricating and ophthalmic topical steroid eye drops during treatment with ELAHERE are recommended. Advise patients to avoid use of contact lenses during treatment with ELAHERE unless directed by a healthcare provider.

Refer patients to an eye care professional for an ophthalmic exam including visual acuity and slit lamp exam prior to treatment initiation, every other cycle for the first 8 cycles, and as clinically indicated. Promptly refer patients to an eye care professional for any new or worsening ocular signs and symptoms.

Monitor for ocular toxicity and withhold, reduce, or permanently discontinue ELAHERE based on severity and persistence of ocular adverse reactions.

Pneumonitis
Severe, life-threatening, or fatal interstitial lung disease (ILD), including pneumonitis, can occur in patients treated with ELAHERE.

Pneumonitis occurred in 10% of patients treated with ELAHERE, including 1% with Grade 3 events and 1 patient (0.1%) with a Grade 4 event. One patient (0.1%) died due to respiratory failure in the setting of pneumonitis and lung metastases. One patient (0.1%) died due to respiratory failure of unknown etiology. Pneumonitis led to permanent discontinuation of ELAHERE in 3% of patients.

Monitor patients for pulmonary signs and symptoms of pneumonitis, which may include hypoxia, cough, dyspnea, or interstitial infiltrates on radiologic exams. Infectious, neoplastic, and other causes for such symptoms should be excluded through appropriate investigations. Withhold ELAHERE for patients who develop persistent or recurrent Grade 2 pneumonitis until symptoms resolve to ≤ Grade 1 and consider dose reduction. Permanently discontinue ELAHERE in all patients with Grade 3 or 4 pneumonitis. Patients who are asymptomatic may continue dosing of ELAHERE with close monitoring.

Peripheral Neuropathy (PN)
Peripheral neuropathy occurred in 36% of patients with ovarian cancer treated with ELAHERE across clinical trials; 3% of patients experienced Grade 3 peripheral neuropathy. Peripheral neuropathy adverse reactions included peripheral neuropathy (20%), peripheral sensory neuropathy (9%), paraesthesia (6%), neurotoxicity (3%), hypoaesthesia (1%), peripheral motor neuropathy (0.9%), polyneuropathy (0.3%), and peripheral sensorimotor neuropathy (0.1%). Monitor patients for signs and symptoms of neuropathy, such as paresthesia, tingling or a burning sensation, neuropathic pain, muscle weakness, or dysesthesia. For patients experiencing new or worsening PN, withhold dosage, dose reduce, or permanently discontinue ELAHERE based on the severity of PN.

Embryo-Fetal Toxicity
Based on its mechanism of action, ELAHERE can cause embryo-fetal harm when administered to a pregnant woman because it contains a genotoxic compound (DM4) and affects actively dividing cells.

Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with ELAHERE and for 7 months after the last dose.

ADVERSE REACTIONS
The most common (≥20 %) adverse reactions, including lab abnormalities, were increased aspartate aminotransferase, fatigue, increased alanine aminotransferase, blurred vision, nausea, increased alkaline phosphatase, diarrhea, abdominal pain, keratopathy, peripheral neuropathy, musculoskeletal pain, decreased lymphocytes, decreased platelets, decreased magnesium, decreased hemoglobin, dry eye, constipation, decreased leukocytes, vomiting, decreased albumin, decreased appetite, and decreased neutrophils.

DRUG INTERACTIONS
DM4 is a CYP3A4 substrate. Closely monitor patients for adverse reactions with ELAHERE when used concomitantly with strong CYP3A4 inhibitors.

USE IN SPECIAL POPULATIONS

Lactation
Advise women not to breastfeed during treatment with ELAHERE and for 1 month after the last dose.

Hepatic Impairment
Avoid use of ELAHERE in patients with moderate or severe hepatic impairment (total bilirubin >1.5 ULN).

On September 20, 2024 Actinium Pharmaceuticals, Inc. (NYSE AMERICAN: ATNM) (Actinium or the Company), a leader in the development of Antibody Radiation Conjugates (ARCs) and other targeted radiotherapies, reported the publication of the Phase 3 SIERRA results of Iomab-B in the peer-reviewed Journal of Clinical Oncology (JCO) (Press release, Actinium Pharmaceuticals, SEP 20, 2024, View Source [SID1234646772]). The article, titled, "Randomized Phase III SIERRA Trial of 131I-Apamistamab Before Allogeneic Hematopoietic Cell Transplantation vs Conventional Care for Relapsed/Refractory Acute Myeloid Leukemia" and is available online on the ASCO (Free ASCO Whitepaper) Journal of Clinical Oncology website HERE.

The Phase 3 SIERRA (Study of Iomab-B in Elderly Relapsed Refractory AML) trial was a randomized, multi-center, controlled trial that enrolled 153 patients aged 55 and above with active relapsed or refractory Acute Myeloid Leukemia (r/r AML), including heavily pre-treated patients and those with high-risk characteristics such as a TP53 mutation. The SIERRA trial compared outcomes of patients receiving Iomab-B (Iodine-131-apamistamab) and a bone marrow transplant (BMT) to physician’s choice of salvage chemotherapy and standard allogeneic BMT in the control arm.

The SIERRA trial met the primary endpoint of durable Complete Remission (dCR) of 6-months following initial complete remission after BMT with high statistical significance (p-value of <0.0001) with 22% of patients (13/76) achieving dCR in the Iomab-B arm compared to 0% of patients (0/77) in the control arm. A significant improvement in Event Free Survival (EFS), a secondary endpoint of the SIERRA trial with a Hazard Ratio = 0.22 (p-value <0.0001) was also achieved. SIERRA did not meet the secondary endpoint of overall survival (OS) on an intent to treat basis analysis due to the high crossover rate with nearly 60% of control arm patients receiving Iomab-B followed by a BMT.

The Phase 3 SIERRA results were first presented in a late-breaker presentation at the Transplantation & Cellular Therapy (TCT) Tandem Meetings of the American Society for Transplantation and Cellular Therapy (ASTCT) and the Center for International Blood & Marrow Transplant Research (CIBMTR) in February 2023. Since TCT, the results of the SIERRA trial have been presented in several oral presentations at leading BMT, hematology, nuclear medicine and nursing meetings and congresses in the U.S. and EU. Supplemental analyses of the SIERRA results have shown improved survival outcomes in patients with a TP53 mutation, which is associated with poor outcomes, as well as increased 1-and 2-year overall survival in patients aged 65 and above.

Dr. Sergio Giralt, Deputy Division Head, Division of Hematological Malignancies and Attending Physician, Adult BMT Service at the Memorial Sloan Kettering Cancer Center, and leading SIERRA Trial investigator and corresponding author, said, "The SIERRA trial was important for the field of transplant and demonstrated for the first time in a randomized study that the CD45 antibody-radioconjugate Iomab-B can provide patients with improved access to a potentially curative hematopoietic stem cell transplant, and improved outcomes compared to current chemotherapy-based regimens. Importantly, Iomab-B demonstrated a statistically significant improvement in key efficacy endpoints including durable Complete Remission and event-free survival. The SIERRA trial was conducted as multiple new therapies gained approval and was designed to address the nuances and difficulty of treating this patient population including allowing physician’s choice of care in the control arm given the heterogeneity of treatment across institutions and the crossover design to provide best patient care. Despite multiple drug approvals for patients with AML, there remains no curative options for older patients with relapsed or refractory disease and outcomes for these patients also remain dismal. My fellow investigators and I are disappointed that the SIERRA trial will not support the approval of Iomab-B despite the positive results and significant unmet medical need of this patient population. However, there is continued significant interest from the transplant community to participate in the upcoming phase 3 study with Iomab-B to provide patients access to this important drug candidate."

On August 05, 2024, Actinium announced that after concluding both its clinical and Chemistry, Manufacturing and Controls ("CMC") interactions with the FDA regarding the BLA pathway for Iomab-B, the FDA determined that demonstrating an overall survival benefit in a randomized head-to-head trial is required for a BLA filing, and the SIERRA trial alone will not be adequate for BLA filing.

Sandesh Seth, Actinium’s Chairman and CEO, stated, "We are excited that the SIERRA results have been published in the peer-reviewed Journal of Clinical Oncology. We believe the SIERRA trial was a major advancement for the field of BMT and targeted radiotherapeutics but most importantly for patients with relapsed and refractory AML. We look forward to completing our interactions with the FDA to finalize the specifics of the additional Phase 3 randomized trial and working to secure a U.S. partner for Iomab-B. In doing so, we hope to accelerate Iomab-B reaching patients with high unmet need that can benefit from a bone marrow transplant."

On September 20, 2024 Biosyngen, an innovative biotechnology company specializing in immune cell therapies, reported its groundbreaking technology on gene-modified, functionally enhanced tumor-infiltrating lymphocytes (TILs) derived from liver cancer biopsy samples (Press release, BioSyngen, SEP 20, 2024, View Source [SID1234646771]).

Abstract Title

Pre-clinical Development of Genetically Modified Tumor-infiltrating Lymphocytes using Biopsy Samples from Liver Cancer Patients

Abstract No.

1034P

Tumor-infiltrating lymphocytes (TILs) are heterogeneous lymphocyte populations within the tumor microenvironment that contains T cells capable of recognizing tumor- or virus-associated antigens. In February of this year, the FDA approved the first TIL-based therapy used with IL-2 for advanced metastatic/recurrent melanoma. However, due to the variability in T cell infiltration between hot and cold tumors, differential abundance of antigen-specific T cells with robust immune response functionality, and the dependence of TIL anti-tumor efficacy on concomitant use of high-dose IL-2 combination therapy, the therapeutic applications of non-edited TILs are quite limited outside of melanoma.

To address these challenges, Biosyngen has developed a proprietary platform for expanding TILs from biopsy samples, achieving production of 1011 cells within four weeks. Additionally, the company has established a stable gene modification platform that reprograms TIL metabolism, enhances TIL activity and sustained antitumor efficacy by expressing membrane anchor proteins. Anti-tumor efficacy has significantly enhanced (without IL-2 co-injection) and no obvious toxicity observed.

Biosyngen houses best-in-class proprietary TIL platform aiming to expand the clinical applications of TIL technology with following features:

Efficient Automated TILs Manufacturing System: Pioneering the use of tumor biopsy samples for TIL preparation with the ability to cryopreserve both tumor tissue and final products, overcoming logistical constraints.
Effective In Vitro Gene-engineering System: Employs viral vector technology for stable gene modification, maintaining high gene expression efficiency in TILs.
Enhanced In Vivo Expansion and Persistence: Increased proportion of central memory T cells (TCM) in the final product, leading to prolonged persistence.
Powerful Antitumor Efficacy: Demonstrates strong tumor-killing effects without the need for concomitant use of IL-2.

We look forward to the formal approval of this treatment in Europe, bringing more treatment options and hope to patients there and worldwide."

Paul Tredwell, Executive Vice President of EMENA at Accord, said, "I am thrilled with the CHMP’s positive opinion. This not only strengthens our current partnership with Henlius but also means serplulimab is on track to become part of the treatment landscape for extensive stage small cell lung cancer patients who currently have limited options and face a poor prognosis."

Innovative Approach to Address Clinical Needs of SCLC

According to GLOBOCAN 2022, lung cancer is the most diagnosed and the first mortality cancer around the world. There were more than 2.48 million new cases of lung cancer worldwide in 2022, accounting for 12.4% of all new cancer cases.[1] Small cell lung cancer (SCLC) accounts for 15%–20% of the total number of lung cancer, which is featured by high malignancy, early metastasis, and rapid disease progression, with extremely poor prognosis. SCLC is divided into limited-stage and extensive-stage, with approximately 30%-40% of patients diagnosed at the limited stage and the rest at the extensive stage. With a prevalence of 1-5 per 10,000 people in the European community, SCLC has an orphan disease designation.[2] In December 2022, HANSIZHUANG was granted orphan drug designation by the European Commission (EC) for the treatment of SCLC, and in March 2023, EMA validated the marketing authorisation application (MAA) of HANSIZHUANG for ES-SCLC.

The positive opinion from CHMP is primarily based on ASTRUM-005, a randomized, double-blind, placebo-controlled international multi-centre clinical study, which evaluated the efficacy and adverse event profile of the PD-1 inhibitor serplulimab plus chemotherapy compared with placebo plus chemotherapy as first-line treatment in patients with ES-SCLC. The study has set up a total of 128 sites in various countries including China, Poland, Turkey, and Georgia, and enrolled 585 subjects, among whom 31.5% were Caucasians. The ASTRUM-005 clinical trial results were firstly presented at the 2022 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and published in the Journal of the American Medical Association (JAMA), making it the first study published on JAMA in SCLC immunotherapy. Based on the ASTRUM-005 study, HANSIZHUANG has been approved in China and Southeast Asian countries for first-line treatment of ES-SCLC, making it the world’s first anti-PD-1 mAb approved for first-line treatment of SCLC.

Global Strategy to Fuel Innovation-driven Expansion

HANSIZHUANG, Henlius’ first innovative mAb developed in-house, focuses on high-incidence cancers such as lung cancer and gastrointestinal tumours. In China, it has been approved by the NMPA for the treatment of microsatellite instability-high (MSI-H) solid tumours, squamous non-small cell lung cancer (sqNSCLC), ES-SCLC, and esophageal squamous cell carcinoma (ESCC). The company is also conducting more than 10 clinical studies on immuno-oncology combination therapies worldwide.

Notably, Henlius covers the full range of first-line treatment of lung cancer. In addition to sqNSCLC and ES-SCLC, HANSIZHUANG’s marketing application for first-line treatment of non-squamous NSCLC (nsNSCLC) has been accepted by the National Medical Products Administration (NMPA). Additionally, the company is conducting a phase 3 international multi-centre clinical trial of HANSIZHUANG combined with chemotherapy and radiotherapy for limited-stage SCLC (LS-SCLC). Henlius is also running a bridging head-to-head trial in the U.S. to compare HANSIZHUANG with standard of care Atezolizumab (anti-PD-L1 mAb) for the first-line treatment of ES-SCLC, which is expected to propel the product towards U.S. market approval further.

The global expansion of HANSIZHUANG is accelerating. It has already been approved in several countries, including China, Indonesia, Cambodia, and Thailand, and has been licensed to over 70 countries and regions, including the US, Europe, Southeast Asia, the Middle East, and North Africa. On December 2023, Henlius received the European Union (EU) GMP Certificates for the production lines of HANSIZHUANG, marking that the company’s Xuhui Facility and Songjiang First Plant have successfully passed the EU GMP on-site inspection for HANSIZHUANG and meet the EU GMP standards. The first overseas shipment of HANSIZHUANG was completed in Q1 2024, making it the first Chinese anti-PD-1 mAb to enter Southeast Asian, offering new treatment options for more global patients.

Looking ahead, Henlius will continue to prioritize patient needs, address unmet clinical demands, and accelerate efforts to deliver high-quality biologics from China to patients worldwide.
