What is the purpose of this trial?This trial is testing ABN401, a new drug, in patients with advanced cancers that have a specific genetic change. The drug works by blocking a protein that helps cancer cells grow, aiming to stop or slow down the cancer.
Is the drug ABN401 a promising treatment for solid tumors?The information provided does not directly mention ABN401 or its effectiveness for solid tumors. Therefore, we cannot determine if ABN401 is a promising treatment based on the given research articles.123415
What safety data is available for ABN401 (Babamekip, vabametkib) in treating solid tumors?The provided research does not mention ABN401, Babamekip, or vabametkib specifically. However, it discusses the safety of BRAF and MEK inhibitors, particularly dabrafenib and trametinib, in treating BRAF-mutant cancers like melanoma and non-small cell lung cancer (NSCLC). These treatments are generally well-tolerated, with common adverse events including pyrexia, nausea, diarrhea, fatigue, edema, and vomiting. Most adverse events are mild to moderate and manageable with dose adjustments. The safety profile of these inhibitors suggests that similar treatments, like ABN401, may have comparable safety characteristics, but specific data for ABN401 is not provided in the research.5671214
What data supports the idea that ABN401 for Solid Tumors is an effective drug?The available research does not provide specific data on the effectiveness of ABN401 for Solid Tumors. Instead, it discusses other treatments for different conditions, such as crizotinib for lung cancer and MEK inhibitors for melanoma. Without direct evidence or comparison to other treatments for solid tumors, we cannot conclude the effectiveness of ABN401 based on the provided information.89101113

Phase I trial with biomarker studies of vatalanib (PTK787) in patients with newly diagnosed glioblastoma treated with enzyme inducing anti-epileptic drugs and standard radiation and temozolomide. [2021]Targeting angiogenesis in glioblastoma (GBM) may improve patient outcome by normalizing tumor vasculature and improving delivery of chemotherapeutics and oxygen. Consequently, concomitant administration of small molecule inhibitors of the VEGF pathway will likely have a positive impact on chemoradiation treatment outcome. We conducted a Phase I study of vatalanib, a small molecule inhibitor of VEGFR, PDGFR, and c-kit in patients with newly diagnosed GBM receiving radiation, temozolomide, and an enzyme-inducing anti-epileptic drug in order to determine the MTD of vatalanib in this patient population. We incorporated circulating biomarker and SNP analyses and pharmacokinetic studies. Nineteen patients were enrolled and the MTD was not reached at the time of study termination. Vatalanib was well tolerated with only 2 DLTs (thrombocytopenia and elevated transaminases). Other grade 3/4 toxicities included leukopenia, lymphopenia, neutropenia, and hand-foot syndrome. There were no wound-healing complications. Of the 13 patients evaluable for a radiographic response, 2 had a partial response and 9 had stable disease. Vatalanib significantly increased PlGF and sVEGFR1 in plasma circulation and decreased sVEGFR2 and sTie2. Plasma collagen IV increased significantly by day 50 of treatment. Vatalanib was well tolerated and this study demonstrates the safety of oral small molecule inhibitors in newly diagnosed GBM patients. Blood biomarkers may be useful as pharmacodynamic markers of response to anti-angiogenic therapies.
Treatment of brain metastases: chemotherapy. [2021]Although systemic therapy is the primary therapeutic modality for disseminated cancer, it plays a limited role in the treatment of brain metastases (BM). This review discusses the blood-brain barrier (BBB), interactions of systemic therapy with supportive care agents used in BM patients, the role of primary tumor sensitivity in the treatment of BM, and unique issues related to the specific primary tumor histologies. The specialized physiology of the brain vasculature that forms the BBB may preclude large and/or water-soluble systemic agents from reaching BM. Once metastases grow larger than 1-2 mm, there is preclinical and clinical evidence that the BBB is at least partially disrupted. Thus, the best treatment strategy in established BM may be to use an agent that is effective against the primary tumor regardless of its apparent BBB permeability. The use of anticonvulsants and corticosteroids must be carefully considered as they can decrease the effectiveness of systemic anti-tumor therapy. Despite the absence of level I data to routinely recommend the use of systemic therapy for solid tumor BM, these treatments should be considered in patients with good performance status and multiple, small metastases, especially if the primary tumor is chemosensitive. The systemic treatment of BM will continue to evolve as effective small-molecule inhibitors are developed and treatment regimens for each specific primary tumor are optimized.
Phase I trial, pharmacokinetics, and pharmacodynamics of vandetanib and dasatinib in children with newly diagnosed diffuse intrinsic pontine glioma. [2022]Testing of promising drug combinations is crucial in the treatment of diffuse intrinsic pontine glioma (DIPG). As the VEGF and platelet-derived growth factor (PDGF) pathways are critical in gliomas, we evaluated the safety, maximum tolerated dose (MTD), pharmacokinetics, and pharmacodynamics of vandetanib, a VEGFR-2 inhibitor, combined with dasatinib, a potent PDGFR inhibitor, during and after radiotherapy in children with newly diagnosed DIPG.
Patient-derived glioblastoma cells show significant heterogeneity in treatment responses to the inhibitor-of-apoptosis-protein antagonist birinapant. [2018]Resistance to temozolomide (TMZ) greatly limits chemotherapeutic effectiveness in glioblastoma (GBM). Here we analysed the ability of the Inhibitor-of-apoptosis-protein (IAP) antagonist birinapant to enhance treatment responses to TMZ in both commercially available and patient-derived GBM cells.
The safety and efficacy of dabrafenib and trametinib for the treatment of melanoma. [2017]The introduction of BRAF and MEK inhibitors into clinical practice improved the prognosis of metastatic melanoma patients. The combination of BRAF inhibitor dabrafenib with MEK inhibitor trametinib has shown its superiority to single agent therapy and is characterized by a tolerable spectrum of adverse events which shows a decrease in incidence over time on treatment. Areas covered: The current scientific literature on safety and adverse events (AEs) related to BRAF and MEK-inhibition has been investigated with special focus on the large phase 3 studies (COMBI-v, COMBI-d and CoBRIM) as well as recent updates presented at oncology and melanoma meetings. Additionally, published case series/case reports were screened for information on AEs. Expert opinion: Even though almost every patient (98%) under combination therapy with dabrafenib and trametinib experiences at least one adverse event, these are generally mild to moderate, reversible and can be managed with dose reductions or interruptions. However, due to an increased life expectancy, there is a substantial need to prevent and treat also mild adverse events, as they play a central role for the quality of life of patients. Ongoing clinical trials will have to demonstrate the efficacy as well as safety of triple combination with anti-PD-1/anti-PD-L1 antibodies.
BRAF in non-small cell lung cancer (NSCLC): Pickaxing another brick in the wall. [2022]Molecular characterization of non-small cell lung cancer (NSCLC) marked an historical turning point for the treatment of lung tumors harboring kinase alterations suitable for specific targeted drugs inhibition, translating into major clinical improvements. Besides EGFR, ALK and ROS1, BRAF represents a novel therapeutic target for the treatment of advanced NSCLC. BRAF mutations, found in 1.5-3.5% of NSCLC, are responsible of the constitutive activation of mitogen activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) pathway. Clinical trials evaluating the efficacy of the BRAF inhibitor dabrafenib in combination with the downstream MEK inhibitor trametinib in metastatic BRAFV600E-mutated NSCLC guaranteed FDA and EMA rapid approval of the combination regimen in this clinical setting. In line with the striking results observed in metastatic melanoma harboring the same molecular alteration, BRAF and MEK inhibition should be considered a new standard of care in this molecular subtype of NSCLC. In the present review, we propose an overview of the available evidence about BRAF in NSCLC mutations (V600E and non-V600E), from biological significance to emerging clinical implications of BRAF mutations detection. Focusing on the current strategies to act against the mutated kinase, we moreover approach additional strategies to overcome treatment resistance.
E6201, an intravenous MEK1 inhibitor, achieves an exceptional response in BRAF V600E-mutated metastatic malignant melanoma with brain metastases. [2022]Malignant melanoma (MM) exhibits a high propensity for central nervous system dissemination with ~50% of metastatic MM patients developing brain metastases (BM). Targeted therapies and immune checkpoint inhibitors have improved overall survival for MM patients with BM. However, responses are usually of short duration and new agents that effectively penetrate the blood brain barrier (BBB) are needed. Here, we report a MM patient with BM who experienced an exceptional response to E6201, an ATP-competitive MEK1 inhibitor, on a Phase 1 study, with ongoing near-complete response and overall survival extending beyond 8 years. Whole exome and transcriptome sequencing revealed a high mutational burden tumor (22 mutations/Megabase) with homozygous BRAF V600E mutation. Correlative preclinical studies demonstrated broad activity for E6201 across BRAF V600E mutant melanoma cell lines and effective BBB penetration in vivo. Together, these results suggest that E6201 may represent a potential new treatment option for BRAF-mutant MM patients with BM.
Comparative efficacy of brigatinib versus ceritinib and alectinib in patients with crizotinib-refractory anaplastic lymphoma kinase-positive non-small cell lung cancer. [2020]Brigatinib, ceritinib, and alectinib are approved to treat crizotinib-refractory anaplastic lymphoma kinase-positive (ALK+) non-small cell lung cancer (NSCLC), but no trial has compared them head-to-head. A matching-adjusted indirect comparison (MAIC) was conducted to estimate the relative efficacy of these agents in the crizotinib-refractory setting.
Profound MEK inhibitor response in a cutaneous melanoma harboring a GOLGA4-RAF1 fusion. [2023]BRAF and CRAF are critical components of the MAPK signaling pathway which is activated in many cancer types. In approximately 1% of melanomas, BRAF or CRAF are activated through structural arrangements. We describe here a metastatic melanoma with a GOLGA4-RAF1 fusion and pathogenic variants in CTNNB1 and CDKN2A. Anti-CTLA4/anti-PD1 combination immunotherapy failed to control tumor progression. In the absence of other actionable variants the patient was administered MEK inhibitor therapy on the basis of its potential action against RAF1 fusions. This resulted in a profound and clinically significant response. We demonstrated that GOLGA4-RAF1 expression was associated with ERK activation, elevated expression of the RAS/RAF downstream co-effector ETV5, and a high Ki67 index. These findings provide a rationale for the dramatic response to targeted therapy. This study shows that thorough molecular characterization of treatment-resistant cancers can identify therapeutic targets and personalize management, leading to improved patient outcomes.
Clinical features and outcomes of ALK rearranged non-small cell lung cancer with primary resistance to crizotinib. [2020]Crizotinib is associated with a favorable survival benefit in patients with ALK-positive non-small cell lung cancer (NSCLC); however, a subset of patients harboring ALK rearrangement shows a poor response.
Multikinase Inhibitor Crizotinib Is Active in MET Exon 14-Altered Lung Cancer. [2020]Crizotinib showed efficacy in non-small cell lung cancer (NSCLC) with alterations in MET exon 14.
Interim analysis for post-marketing surveillance of dabrafenib and trametinib combination therapy in Japanese patients with unresectable and metastatic melanoma with BRAF V600 mutation. [2022]To investigate the safety and efficacy of dabrafenib and trametinib combination therapy for BRAF V600 mutation-positive unresectable and metastatic melanoma in over 100 Japanese patients of a real-world clinical setting.
An open label, non-randomised, phase IIIb study of trametinib in combination with dabrafenib in patients with unresectable (stage III) or distant metastatic (stage IV) BRAF V600-mutant melanoma: A subgroup analysis of patients with brain metastases. [2022]Despite the poor prognosis associated with melanoma brain metastases (BM), data concerning these patients and their inclusion in clinical trials remains scarce. We report here the efficacy results of a subgroup analysis in patients with BRAFV600-mutant melanoma and BM treated with BRAF and MEK inhibitors dabrafenib (D) and trametinib (T).
BRAF Inhibitors in Non-Small Cell Lung Cancer. [2022]RAF family proteins are serine-threonine kinases that play a central role in the MAPK pathway which is involved in embryogenesis, cell differentiation, cell proliferation and death. Deregulation of this pathway is found in up to 30% of all human cancers and BRAF mutations can be identified in 1.5-3.5% of NSCLC patients. Following the positive results obtained through the combination of BRAF and MEK inhibitors in BRAF-mutant melanoma, the same combination was prospectively assessed in BRAF-mutant NSCLC. In cohort B of the BRF113928 trial, 57 pretreated NSCLC patients were treated with dabrafenib plus trametinib: an ORR of 68.4%, a disease control rate of 80.7%, a median PFS of 10.2 months and a median OS of 18.2 months were observed. Similar results were reported in the first-line setting (cohort C), with an ORR of 63.9%, a DCR of 75% and a median PFS and OS of 10.2 and 17.3 months, respectively. The combination was well tolerated: the main adverse events were pyrexia (64%), nausea (56%), diarrhoea (56%), fatigue (36%), oedema (36%) and vomiting (33%). These positive results led to the approval of the combination of dabrafenib and trametinib for the treatment of BRAF V600E metastatic NSCLC patients regardless of previous therapy. Ongoing research should better define the role of new generation RAF inhibitors for patients with acquired resistance, the activity of chemo-immunotherapy or the combination of TKIs with chemotherapy or with immunotherapy in patients with BRAF-mutated cancers.
The CNS-penetrating taxane drug TPI 287 potentiates antiglioma activity of the AURKA inhibitor alisertib in vivo. [2023]Glioblastoma (GBM) has a very poor prognosis despite current treatment. We previously found cytotoxic synergy between the AURKA inhibitor alisertib and the CNS-penetrating taxane TPI 287 against GBM tumor cells in vitro.
