Approximately 85% of lung cancers are classified as NSCLC1 and despite advances in treatment, lung cancer remains the leading cause of cancer-related deaths throughout the world.2 The c-Met protein is a receptor tyrosine kinase found to be overexpressed in approximately 25% of advanced EGFR wild type, nonsquamous NSCLC patients3 and is associated with a poor prognosis.4,5,6 Teliso-V is being evaluated within this patient population who currently have very limited treatment options.

"Patients with non-small cell lung cancer have unmet medical needs and oncologists are looking for new treatment options for these patients who unfortunately have a poor prognosis," said Roopal Thakkar, M.D., executive vice president, research and development, chief scientific officer, AbbVie. "We are hopeful that Teliso-V will be a differentiated treatment for certain patients as we look to elevate the standards of care in oncology."

In December 2021, Teliso-V was granted Breakthrough Therapy Designation by the FDA. The BLA submission is supported by data from Phase 2 LUMINOSITY trial (Study M14-239), an ongoing study designed to characterize the safety and efficacy of Teliso-V in c-Met overexpressing NSCLC populations. Data from the LUMINOSITY study were recently presented at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) congress and topline data from this trial were shared in 2023. Teliso-V is being further evaluated as a monotherapy in patients with previously treated c-Met overexpressing NSCLC in the randomized Phase 3 confirmatory global study TeliMET NSCLC-01. Enrollment in the study is underway and continues across global clinical trial sites. Additional information on clinical trials for Teliso-V is available at www.clinicaltrials.gov.

About Telisotuzumab Vedotin (Teliso-V)
Teliso-V is an investigational, first-in-class, c-Met protein directed antibody-drug conjugate (ADC) designed to target c-Met overexpressing tumors. c-Met is a receptor tyrosine kinase that can be overexpressed in many solid tumors including NSCLC. Further information on clinical trials for Teliso-V is available at View Source Teliso-V is not approved by any health regulatory authority.

About the LUMINOSITY Trial
The LUMINOSITY trial (M14-239), is an ongoing Phase 2 study designed to identify the target NSCLC populations that overexpress c-Met best suited for Teliso-V monotherapy in the second-line or third-line setting, and then to expand the groups to further evaluate efficacy in the selected populations. The endpoints include overall response rate (ORR), duration of response (DoR), disease control rate (DCR) and progression-free survival (PFS) per independent central review (ICR) as well as overall survival (OS).

Molecular Partners is developing a unique and innovative RDT platform for targeted delivery of radioactive payloads to solid tumors. Due to their small size, high specificity and affinity, DARPins are well-suited as vector for efficient delivery of therapeutic radionuclides. In June 2024, Molecular Partners, together with Targeted Alpha Therapy pioneers Orano Med, announced MP0712, a 212Pb-labeled DLL3-targeting radiopharmaceutical as their first co-developed RDT candidate.

DLL3 is a priority target for radiopharmaceutical therapy thanks to its abundant expression in tumors of patients with SCLC (>85%) and other aggressive neuroendocrine tumors, while expression in healthy tissues is low.

At EANM 2024, Molecular Partners will present their preclinical results supporting MP0712 as a promising treatment candidate for SCLC, with an attractive biodistribution profile, potent antitumor activity and a good safety profile.

Novel combination of TALVEY® (talquetamab-tgvs) and TECVAYLI® (teclistamab-cqyv) suggests high response rates and durable responses in triple-class refractory patients with relapsed or refractory multiple myeloma, including those with extramedullary disease

On September 27, 2024 Johnson & Johnson (NYSE: JNJ) reported updated results from the investigational Phase 1b RedirecTT-1 study evaluating the first-ever bispecific antibody combination of TALVEY (talquetamab-tgvs), the first and only FDA-approved bispecific targeting GPRC5D, and TECVAYLI (teclistamab-cqyv), the first FDA-approved BCMA-directed bispecific therapy, showing high response rates and durable responses, with a consistent safety profile to each monotherapy, in patients with relapsed or refractory multiple myeloma (RRMM) who were triple-class exposed, including those with extramedullary disease (Press release, Johnson & Johnson, SEP 27, 2024, View Source;302261023.html [SID1234646902]).

"As multiple myeloma progresses, it becomes more difficult to treat, especially in patients with extramedullary disease, which spreads beyond the bone marrow and typically becomes resistant to standard therapies," said Yael Cohen, M.D., Head of Myeloma Unit, Hematology Institute, Tel Aviv Sourasky Medical Center, Israel, and principal study investigator.* "These results reflect promising efficacy and a manageable safety profile for this combination of two first-in-class, innovative bispecific therapies and provide a potentially promising off-the-shelf option for patients with advanced multiple myeloma."

At data cutoff, 44 patients had been treated with the recommended phase 2 regimen (RP2R) of 0.8 mg/kg of TALVEY in combination with 3 mg/kg of TECVAYLI every other week, the overall response rate (ORR) was 79.5 percent, with a complete response or better (CR+) rate of 52.3 percent, an 18-month duration of response (DOR) of 85.9 percent, and an 18-month progression-free survival (PFS) rate of 69.8 percent with median follow-up of 18.2 months.1

Results from a subgroup analysis of patients with extramedullary disease (EMD; ≥1 bone-independent lesion of ≥2 cm), a patient population often facing limited treatment options, demonstrated meaningful ORR and DOR for bispecific antibody-based treatment. At the RP2R (n=18), results showed an ORR of 61.1 percent, with CR+ rate of 33.3 percent, an 18-month DOR of 81.8 percent, and an 18-month PFS rate of 52.9 percent in patients with EMD at median follow-up 13.6 months.1

The combination of TALVEY and TECVAYLI had a safety profile that was consistent with the known safety profiles of each agent as monotherapy. Cumulative incidence of Grade 3/4 infections was slightly higher than that seen with either agent as monotherapy but plateaued from six months, and non-hematologic adverse events were generally low grade, including taste (50 percent) and non-rash skin (56.8 percent) and nail (47.7 percent) AEs, with no discontinuations due to cytopenias.1

"TALVEY and TECVAYLI have already demonstrated powerful efficacy as standalone therapies as first-in-class bispecifics in the clinical and real-world settings," said Jordan Schecter, M.D., Vice President, Disease Area Leader, Multiple Myeloma, Innovative Medicine at Johnson & Johnson. "We continue to research this innovative combination, as this study demonstrates both the efficacy and manageable safety profile of this combination, particularly in hard-to-treat patients such as those with EMD, as well as the combinability of TALVEY with other effective therapies."

Additional data underscoring the combinability of TALVEY from the TRIMM-2 study will also be presented at IMS. First results from the RedirecTT-1 study were presented at the 2023 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting.

About RedirecTT
The RedirecTT-1 (NCT04586426) study is an ongoing Phase 1b dose escalation study of the combination of the bispecific T-cell redirection antibodies TALVEY and TECVAYLI in patients (n=208) with relapsed or refractory multiple myeloma. The primary objective is to identify the recommended Phase 2 regimen(s) (RP2R[s]) and schedule for the study treatment and to characterize the safety of the RP2R(s) for the study treatment. In part 1, patients will receive TALVEY and TECVAYLI with or without daratumumab in 28-day cycles following initial step-up doses. In part 2, patients will receive treatment doses (combination of TALVEY and TECVAYLI and daratumumab + TALVEY + TECVAYLI regimens) which will be determined by the recommended Phase 2 regimen (s) (RP2R[s]) of the study treatment identified in Part 1. In part 3, patients will receive TALVEY + TECVAYLI combination therapy, at the RP2R selected from Part 1 and Part 2.

About Multiple Myeloma
Multiple myeloma is a blood cancer affecting a type of white blood cell called plasma cells found in the bone marrow.2 In multiple myeloma, these malignant plasma cells proliferate and replace normal cells in the bone marrow.3 Multiple myeloma is the second most common blood cancer worldwide and remains an incurable disease.4 In 2024, it is estimated that more than 35,000 people will be diagnosed with multiple myeloma in the U.S. and more than 12,000 will die from the disease.5 People with multiple myeloma have a 5-year survival rate of 59.8 percent.6 While some people diagnosed with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels, kidney problems or infections.7,8

About TALVEY
TALVEY (talquetamab-tgvs) received approval from the U.S. FDA in August 2023 as a first-in-class GPRC5D-targeting bispecific antibody for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 antibody.8 Since FDA approval, 1,500 patients were treated with TALVEY. The European Commission (EC) granted conditional marketing authorization (CMA) of TALVEY (talquetamab-tgvs) in August 2023 as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma (RRMM) who have received at least three prior therapies, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody and have demonstrated disease progression on the last therapy.9

TALVEY is a bispecific T cell engaging antibody that binds to the CD3 receptor expressed on the surface of T cells and G protein-coupled receptor class C group 5 member D (GPRC5D), a novel multiple myeloma target which is highly expressed on the surface of multiple myeloma cells and non-malignant plasma cells, as well as some healthy tissues such as epithelial cells of the skin and tongue.

IMPORTANT SAFETY INFORMATION

WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGIC TOXICITY, including IMMUNE EFFECTOR CELL-ASSOCIATED NEUROTOXICITY SYNDROME

Cytokine release syndrome (CRS), including life-threatening or fatal reactions, can occur in patients receiving TALVEY. Initiate TALVEY treatment with step-up dosing to reduce the risk of CRS. Withhold TALVEY until CRS resolves or permanently discontinue based on severity.

Neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS), and serious and life-threatening or fatal reactions, can occur with TALVEY. Monitor patients for signs and symptoms of neurologic toxicity including ICANS during treatment. Withhold or discontinue TALVEY based on severity.

Because of the risk of CRS and neurologic toxicity, including ICANS, TALVEY is available only through a restricted program called the TECVAYLI and TALVEY Risk Evaluation and Mitigation Strategy (REMS).

CONTRAINDICATIONS: None.

WARNINGS AND PRECAUTIONS

Cytokine Release Syndrome (CRS): TALVEY can cause cytokine release syndrome, including life-threatening or fatal reactions. In the clinical trial, CRS occurred in 76% of patients who received TALVEY at the recommended dosages, with Grade 1 CRS occurring in 57% of patients, Grade 2 in 17%, and Grade 3 in 1.5%. Recurrent CRS occurred in 30% of patients. CRS occurred in 33% of patients with step-up dose 3 in the biweekly dosing schedule (N=153). CRS occurred in 30% of patients with the first 0.4 mg/kg treatment dose and in 12% of patients treated with the first 0.8 mg/kg treatment dose. The CRS rate for both dosing schedules combined was less than 3% for each of the remaining doses in Cycle 1 and less than 3% cumulatively from Cycle 2 onward. The median time to onset of CRS was 27 (range: 0.1 to 167) hours from the last dose, and the median duration was 17 (range: 0 to 622) hours. Clinical signs and symptoms of CRS include but are not limited to pyrexia, hypotension, chills, hypoxia, headache, and tachycardia. Potentially life-threatening complications of CRS may include cardiac dysfunction, acute respiratory distress syndrome, neurologic toxicity, renal and/or hepatic failure, and disseminated intravascular coagulation (DIC).

Initiate therapy with step-up dosing and administer pre-treatment medications (corticosteroids, antihistamine, and antipyretics) prior to each dose of TALVEY in the step-up dosing schedule to reduce the risk of CRS. Monitor patients following administration accordingly. In patients who experience CRS, pre-treatment medications should be administered prior to the next TALVEY dose.

Counsel patients to seek medical attention should signs or symptoms of CRS occur. At the first sign of CRS, immediately evaluate patient for hospitalization and institute treatment with supportive care based on severity, and consider further management per current practice guidelines. Withhold TALVEY until CRS resolves or permanently discontinue based on severity.

Neurologic Toxicity including ICANS: TALVEY can cause serious or life-threatening neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS), including fatal reactions. In the clinical trial, neurologic toxicity occurred in 55% of patients who received the recommended dosages, with Grade 3 or 4 neurologic toxicity occurring in 6% of patients. The most frequent neurologic toxicities were headache (20%), encephalopathy (15%), sensory neuropathy (14%), and motor dysfunction (10%).

ICANS was reported in 9% of 265 patients where ICANS was collected and who received the recommended dosages. Recurrent ICANS occurred in 3% of patients. Most patients experienced ICANS following step-up dose 1 (3%), step-up dose 2 (3%), step-up dose 3 of the biweekly dosing schedule (1.8%), or the initial treatment dose of the weekly dosing schedule (2.6%) (N=156) or the biweekly dosing schedule (3.7%) (N=109). The median time to onset of ICANS was 2.5 (range: 1 to 16) days after the most recent dose with a median duration of 2 (range: 1 to 22) days. The onset of ICANS can be concurrent with CRS, following resolution of CRS, or in the absence of CRS. Clinical signs and symptoms of ICANS may include but are not limited to confusional state, depressed level of consciousness, disorientation, somnolence, lethargy, and bradyphrenia.

Monitor patients for signs and symptoms of neurologic toxicity during treatment. At the first sign of neurologic toxicity, including ICANS, immediately evaluate the patient and provide supportive care based on severity; withhold or permanently discontinue TALVEY based on severity and consider further management per current practice guidelines. [see Dosage and Administration (2.5)].

Due to the potential for neurologic toxicity, patients receiving TALVEY are at risk of depressed level of consciousness. Advise patients to refrain from driving or operating heavy or potentially dangerous machinery during the step-up dosing schedule and for 48 hours after completion of the step-up dosing schedule, and in the event of new onset of any neurological symptoms, until symptoms resolve.

TECVAYLI and TALVEY REMS: TALVEY is available only through a restricted program under a REMS, called the TECVAYLI and TALVEY REMS because of the risks of CRS and neurologic toxicity, including ICANS.

Further information about the TECVAYLI and TALVEY REMS program is available at www.TEC-TALREMS.com or by telephone at 1-855-810-8064.

Oral Toxicity and Weight Loss: TALVEY can cause oral toxicities, including dysgeusia, dry mouth, dysphagia, and stomatitis. In the clinical trial, 80% of patients had oral toxicity, with Grade 3 occurring in 2.1% of patients who received the recommended dosages. The most frequent oral toxicities were dysgeusia (49%), dry mouth (34%), dysphagia (23%), and ageusia (18%). The median time to onset of oral toxicity was 15 (range: 1 to 634) days, and the median time to resolution to baseline was 43 (1 to 530) days. Oral toxicity did not resolve to baseline in 65% of patients.

TALVEY can cause weight loss. In the clinical trial, 62% of patients experienced weight loss of 5% or greater, regardless of having an oral toxicity, including 28% of patients with Grade 2 (10% or greater) weight loss and 2.7% of patients with Grade 3 (20% or greater) weight loss. The median time to onset of Grade 2 or higher weight loss was 67 (range: 6 to 407) days, and the median time to resolution was 50 (range: 1 to 403) days. Weight loss did not resolve in 57% of patients who reported weight loss.

Monitor patients for signs and symptoms of oral toxicity. Counsel patients to seek medical attention should signs or symptoms of oral toxicity occur and provide supportive care as per current clinical practice, including consultation with a nutritionist. Monitor weight regularly during therapy. Evaluate clinically significant weight loss further. Withhold TALVEY or permanently discontinue based on severity.

Infections: TALVEY can cause infections, including life-threatening or fatal infections. Serious infections occurred in 16% of patients, with fatal infections in 1.5% of patients. Grade 3 or 4 infections occurred in 17% of patients. The most common serious infections reported were bacterial infection (8%), which included sepsis and COVID-19 (2.7%).

Monitor patients for signs and symptoms of infection prior to and during treatment with TALVEY and treat appropriately. Administer prophylactic antimicrobials according to local guidelines. Withhold or consider permanently discontinuing TALVEY as recommended, based on severity.

Cytopenias: TALVEY can cause cytopenias, including neutropenia and thrombocytopenia. In the clinical trial, Grade 3 or 4 decreased neutrophils occurred in 35% of patients, and Grade 3 or 4 decreased platelets occurred in 22% of patients who received TALVEY. The median time to onset for Grade 3 or 4 neutropenia was 22 (range: 1 to 312) days, and the median time to resolution to Grade 2 or lower was 8 (range: 1 to 79) days. The median time to onset for Grade 3 or 4 thrombocytopenia was 12 (range: 2 to 183) days, and the median time to resolution to Grade 2 or lower was 10 (range: 1 to 64) days. Monitor complete blood counts during treatment and withhold TALVEY as recommended, based on severity.

Skin Toxicity: TALVEY can cause serious skin reactions, including rash, maculo-papular rash, erythema, and erythematous rash. In the clinical trial, skin reactions occurred in 62% of patients, with grade 3 skin reactions in 0.3%. The median time to onset was 25 (range: 1 to 630) days. The median time to improvement to grade 1 or less was 33 days.

Monitor for skin toxicity, including rash progression. Consider early intervention and treatment to manage skin toxicity. Withhold TALVEY as recommended based on severity.

Hepatotoxicity: TALVEY can cause hepatotoxicity. Elevated ALT occurred in 33% of patients, with grade 3 or 4 ALT elevation occurring in 2.7%; elevated AST occurred in 31% of patients, with grade 3 or 4 AST elevation occurring in 3.3%. Grade 3 or 4 elevations of total bilirubin occurred in 0.3% of patients. Liver enzyme elevation can occur with or without concurrent CRS.

Monitor liver enzymes and bilirubin at baseline and during treatment as clinically indicated. Withhold TALVEY or consider permanent discontinuation of TALVEY, based on severity [see Dosage and Administration (2.5)].

Embryo-Fetal Toxicity: Based on its mechanism of action, TALVEY may cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus.

Neutropenia – TECVAYLI can cause neutropenia and febrile neutropenia. In patients who received TECVAYLI at the recommended dose in the clinical trial, decreased neutrophils occurred in 84% of patients, with Grade 3 or 4 decreased neutrophils in 56%. Febrile neutropenia occurred in 3% of patients.

Monitor complete blood cell counts at baseline and periodically during treatment and provide supportive care per local institutional guidelines. Monitor patients with neutropenia for signs of infection. Withhold TECVAYLI based on severity.

Hypersensitivity and Other Administration Reactions – TECVAYLI can cause both systemic administration-related and local injection-site reactions. Systemic Reactions – In patients who received TECVAYLI at the recommended dose in the clinical trial, 1.2% of patients experienced systemic-administration reactions, which included Grade 1 recurrent pyrexia and Grade 1 swollen tongue. Local Reactions – In patients who received TECVAYLI at the recommended dose in the clinical trial, injection-site reactions occurred in 35% of patients, with Grade 1 injection-site reactions in 30% and Grade 2 in 4.8%. Withhold TECVAYLI or consider permanent discontinuation of TECVAYLI based on severity.

Embryo-Fetal Toxicity – Based on its mechanism of action, TECVAYLI may cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with TECVAYLI and for 5 months after the last dose.

ADVERSE REACTIONS

The most common adverse reactions (≥20%) were pyrexia, CRS, musculoskeletal pain, injection site reaction, fatigue, upper respiratory tract infection, nausea, headache, pneumonia, and diarrhea. The most common Grade 3 to 4 laboratory abnormalities (≥20%) were decreased lymphocytes, decreased neutrophils, decreased white blood cells, decreased hemoglobin, and decreased platelets.

RefleXion Showcases Pioneering Multi-Target Treatment (MTT) and Early Clinical Highlights at ASTRO

On September 26, 2024 RefleXion Medical, an external-beam theranostic oncology company, reported it will showcase Multi-target Treatment (MTT), the groundbreaking upgrade for its RefleXion X1 platform (Press release, RefleXion, SEP 26, 2024, View Source [SID1234646886]). This innovation allows physicians to combine SCINTIX biology-guided radiotherapy with conventional stereotactic body radiotherapy (SBRT) in a single plan to treat patients with metastatic disease. The company will also highlight learnings from its early patient treatments.

RefleXion will showcase MTT at the American Society for Radiation Oncology (ASTRO) Annual Meeting, Sept. 29 – Oct. 3, in Washington D.C. (booth #1313), where researchers will present new scientific evidence in 22 presentations, including four oral presentations, showcasing the X1 machine with SCINTIX therapy.

"The results from our first-year patient treatments are highly encouraging," said Sean Shirvani, M.D., M.P.H., chief medical officer at RefleXion. "We are consistently observing that SCINTIX therapy detects and adapts to tumor motion in an autonomous fashion. In the lung, this means that less normal lung tissue is damaged by the ablative zone of radiotherapy. And in the bone, our system provides insurance against unanticipated shifts by the patient when the radiotherapy beam is on.

"Moreover, our clinical partners recognize the immense value of having positron emission tomography or PET data underpinning both treatment planning and delivery. This information has, in several cases, influenced the course of patient therapy," continued Shirvani.

The RefleXion X1 with SCINTIX therapy uses information from an injected PET radiopharmaceutical produced by the cancer itself in real time to determine where to deliver radiation. Because PET data is used to direct treatment, it is also an integral part of the treatment planning process.

In early SCINTIX therapy cases, PET data during treatment planning or delivery demonstrated tumor progression, uncovered additional tumors, or confirmed significant tumor movement in bone tumors, which are generally considered relatively immobile. In the bone tumor cases, SCINTIX technology accurately followed the live PET signal and delivered the dose as planned, a feat not achievable with conventional image-guided radiotherapy.

The following oral presentations highlight some of the new research being presented at ASTRO 2024. Detailed information on all 22 presentations may be found here.
