AbbVie (NYSE: ABBV) today announced that new data from its innovative antibody-drug conjugate (ADC) platform will be showcased across three oral presentations at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting (May 31 - June 4, 2024).
NORTH CHICAGO, Ill., May 28, 2024 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that new data from its innovative antibody-drug conjugate (ADC) platform will be showcased across three oral presentations at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting (May 31 - June 4, 2024). AbbVie’s ADCs are designed to target unique protein biomarkers such as c-Met (MET protein) and SEZ6 (seizure-related homolog 6 protein), which are over-expressed across various tumor types. By utilizing these biomarkers as targets, ADCs are designed to deliver potent cancer cell death-inducing agents called ‘payloads’ to the tumor. “Building upon our strong commitment to patients and existing leadership in hematological malignancies, we are rapidly advancing a differentiated pipeline in solid tumors,” said Daejin Abidoye, M.D., vice president, head of solid tumors, oncology development, AbbVie. “Our ADC platform allows us to utilize selected biomarkers such as c-Met and SEZ6 to induce targeted cancer cell death by delivering potent anti-cancer agents. The data we are presenting at ASCO demonstrate the clinical potential of this approach across a wide range of difficult-to-treat tumors.” Data from the dose-escalation and colorectal cancer (CRC) dose-expansion cohort of an ongoing first-in-human Phase 1 study (NCT05029882) of ABBV-400, a potential best-in-class c-Met directed ADC, will be presented in an oral presentation. The preliminary data show that among 122 heavily pre-treated advanced CRC patients, promising antitumor activity was observed at 2.4 and 3.0 mg/kg doses administered once every 3 weeks, with confirmed objective response rate (ORR) of 18% (n=40) and 24% (n=41) respectively in those groups. In patients with higher c-Met expression, ORR was enriched to >35% at doses ≥2.4 mg/kg. The most common Gr≥3 treatment-emergent adverse events (TEAEs) were anemia (35%), neutropenia (7%) and febrile neutropenia (6%). TEAEs leading to discontinuation occurred in 25 (20.5%) patients. Additional data will be presented at the meeting. ABBV-400 is also being evaluated in a Phase 1b basket study (NCT06084481) in advanced solid tumors as a monotherapy and a Phase 2 study (NCT06107413) in second line metastatic CRC in combination with fluorouracil, folinic acid, and bevacizumab. “c-Met overexpression, found in the majority of patients with metastatic CRC, has been reported to be associated with poor prognosis. However, there are no approved therapies specific for c-Met–overexpressing CRCs, making it an attractive cancer biomarker to target,” said Manish Sharma, M.D., Co-Director of Clinical Research at START Midwest (Grand Rapids, MI) and Principal Investigator on the ABBV-400 trial. “Results from this Phase 1 study show preliminary evidence of efficacy for ABBV-400 in patients with heavily pre-treated colorectal cancer and are supportive of further exploration of this novel ADC in CRC and other solid tumors”. In addition, early data from the monotherapy dose escalation part of a first-in-human study of ABBV-706, a potential best-in-class SEZ6 directed ADC, will be presented at an oral presentation. The data demonstrate that among a total of 48 efficacy-evaluable patients (23 SCLC and 25 NEN), the overall confirmed objective response rate was 43.8%. Within the SCLC group, the confirmed objective response rate was 60.9%. Among all the 53 enrolled patients at the time of data cut-off, the most common ≥3 TEAEs were neutropenia (42%), anemia (42%), and leukopenia (28%). The ongoing study (NCT05599984) is evaluating ABBV-706 as monotherapy or in combination with budigalimab (a programmed cell death 1 inhibitor), carboplatin, or cisplatin, in patients with advanced solid tumors, including SCLC and other NENs. Additional data will be presented at the meeting. Both ABBV-400 and ABBV-706 utilize a novel, AbbVie proprietary topoisomerase 1 inhibitor (Top1i) payload. Top1i is an anticancer agent that induces cell death by interrupting DNA replication. ABBV-400 and ABBV-706 are designed to specifically deliver Top1i to cells expressing c-Met and SEZ6 respectively. AbbVie will also present data from the primary analysis of the Phase 2 LUMINOSITY non-small cell lung cancer (NSCLC) trial evaluating telisotuzumab vedotin (Teliso-V), a potential first-in-class c-Met directed ADC utilizing a microtubule polymerization inhibitor, monomethyl auristatin E (MMAE) payload, in patients with previously treated c-Met-overexpressing, non-squamous, epidermal growth factor receptor (EGFR) wild type, advanced NSCLC. AbbVie previously announced positive topline results from the study in November 2023. Other presentations from AbbVie’s ADC platform include safety and efficacy data in an older population (≥ 65) from the Phase 3 MIRASOL trial of mirvetuximab soravtansine (MIRV) vs investigator’s choice chemotherapy in patients with platinum-resistant ovarian cancer (PROC) and high folate receptor-alpha (FRα) expression, and a retrospective, exploratory pooled analysis characterizing long-term survivors from four clinical trials examining patients with folate receptor alpha-positive recurrent ovarian cancer treated with MIRV monotherapy.

ABOUT ELAHERE® (mirvetuximab soravtansine-gynx) The Marketing Authorization Application (MAA) for ELAHERE in Europe has been accepted by the European Medicines Agency (EMA). Regulatory submissions for ELAHERE are also under review in multiple other countries. INDICATION IMPORTANT SAFETY INFORMATION WARNING: OCULAR TOXICITY
WARNINGS and PRECAUTIONS 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.
