Impact List | missense |
Protein Effect | gain of function |
Gene Variant Descriptions | ALK I1170N lies within the protein kinase domain of the Alk protein (UniProt.org). I1170N confers a gain of function to Alk as demonstrated by increased kinase activity in in vitro assays and transformation in cultured cells (PMID: 33674381, PMID: 25517749). |

ALK act mut | neuroblastoma | predicted - sensitive | Trametinib + Venetoclax | Preclinical - Cell culture | Actionable | In a preclinical study, the addition of Mekinist (trametinib) sensitized a neuroblastoma cell line harboring an ALK activating mutation to Venclexta (venetoclax), resulting in reduced cell viability in culture (PMID: 36895472). | 36895472 |
ALK act mut | neuroblastoma | predicted - sensitive | Navitoclax + Trametinib | Preclinical - Cell culture | Actionable | In a preclinical study, the addition of Mekinist (trametinib) sensitized neuroblastoma cell lines harboring ALK activating mutations to Navitoclax (ABT-263), resulting in reduced cell viability in culture (PMID: 36895472). | 36895472 |
ALK act mut | neuroblastoma | sensitive | Cyclophosphamide + Lorlatinib + Topotecan | Phase I | Actionable | In a Phase I trial, the combination of Lorbrena (lorlatinib), Topotecan, and Cytoxan (cyclophosphamide) treatment was well tolerated and resulted in a modified response rate of 63% (5/8) in pediatric patients with neuroblastoma harboring an ALK activating mutation, including ALK F1174C, F1174L, R1275Q, or R1275L (PMID: 37012551; NCT03107988). | 37012551 |
ALK act mut | neuroblastoma | predicted - sensitive | NVL-655 | Preclinical - Cell culture | Actionable | In a preclinical study, NUV-655 inhibited proliferation of neuroblastoma cell lines harboring activating mutations in ALK in culture (Cancer Res (2022) 82 (12_Supplement): 3337). | detail... |
ALK act mut | neuroblastoma | predicted - sensitive | S63845 + Trametinib | Preclinical - Cell culture | Actionable | In a preclinical study, the addition of Mekinist (trametinib) sensitized a neuroblastoma cell line harboring an ALK activating mutation to S63845 (MIK655), resulting in reduced cell viability in culture (PMID: 36895472). | 36895472 |
ALK act mut | neuroblastoma | sensitive | Lorlatinib | Phase I | Actionable | In a Phase I trial, Lorbrena (lorlatinib) treatment was well tolerated and resulted in a modified response rate of 30% (7/23) in children and 67% (10/15) in adults with neuroblastoma harboring an ALK activating mutation, including ALK F1174C, F1174L, R1275Q, or R1275L, F1245Y, F1245L, D1276_R1279delinsE, or amplification (PMID: 37012551; NCT03107988). | 37012551 |
ALK mutant | lung non-small cell carcinoma | no benefit | Belizatinib | Phase I | Actionable | In a Phase I trial, treatment with Belizatinib (TSR-011) in ALK inhibitor-naive non-small cell lung cancer patients (n=14) harboring either an ALK mutation, ALK amplification, or an ALK rearrangement resulted in a partial response in 6 patients and stable disease in 8 patients, however, it was determined that the drug resulted in limited efficacy and development of the drug was discontinued (PMID: 31217479; NCT02048488). | 31217479 |
ALK mutant | lung non-small cell carcinoma | no benefit | Crizotinib + Onalespib | Phase II | Actionable | In a Phase II trial, Onalespib (AT13387) and Xalkori (crizotinib) combination treatment did not significantly improve median progression free survival (269 vs 266 days) or objective response rate (55.4%, 38/68 vs 45.3%, 31/68) compared to Xalkori (crizotinib) single treatment in patients with non-small cell lung carcinoma harboring either an ALK mutation or ALK rearrangement (J Clin Oncol 34, 2016 (suppl; abstr 9059); NCT01712217). | detail... |
