    Metabolic abnormalities caused by overexpression of glutaminase (one of the key enzymes in glutamine metabolism) (GLS) are one of the main signs of renal cancer (RCC).
    Telaglenastat (Tela) is a pioneering researcher developed , Selective oral GLS inhibitors can prevent the effect of glutamine and block key downstream signaling pathways
    .

    Preclinical studies have shown that Telaglenastat and Cabozantinib (a VEGFR2/MET/AXL inhibitor) can produce synergistic anti-tumor effects
    .

    In the phase I study, Telaglenastat+cabotinib showed better safety and efficacy when used in the second-line treatment of metastatic RCC (mRCC)
    .

    The CANTATA study explored the efficacy and safety of Telaglenastat+Cabotinib versus placebo+Cabotinib in patients with treated metastatic clear cell renal cell carcinoma (NCT03428217)
    .

    At this year's ASCO conference, the study announced preliminary research data
    .

    Methods: Eligible mRCC patients have received 1-2 line system therapy, including ≥1 anti-vascular therapy or nivolumab+ipilimumab, KPS ≥70%, and have measurable lesions assessed according to RECIST 1.
    1 standard.
    He has not been treated with cabozantinib or other MET inhibitors in the past
    .

    The enrolled patients were randomly assigned to receive Cabotinib (60 mg PO QD) + Telaglenastat (800 mg PO BID) or Cabotinib + placebo at a 1:1 ratio until disease progression or unacceptable toxicity occurs
    .

    Stratification factors include whether they have received PD-1/PD-L1 inhibitors and IMDC risk classification
    .

    The primary endpoint was the blinded independent radiology committee (BIRC) assessment of progression-free survival (PFS, assessed according to the RECIST 1.
    1 standard)
    .

    The data deadline is August 31, 2020
    .

    Results: 444 patients were randomized.
    Telaglenastat+cabotinib and placebo+cabotinib had 221 and 223 patients, respectively.
    The baseline characteristics of the two groups were balanced and comparable
    .

    At a median follow-up of 11.
    7 months, 276 patients had previously received immune checkpoint inhibitor therapy, of which 128 patients had previously received nivolumab + ipilimumab
    .

    The median PFS of the Telaglenastat+cabotinib group and the placebo+cabotinib group were 9.
    2 months and 9.
    3 months, respectively (HR = 0.
    94; 95% CI: 0.
    74, 1.
    21; P = 0.
    65).
    The response rate (ORR) was 31% and 28%, respectively
    .

    At the time of data analysis, the overall survival (OS) results were not yet mature
    .

    In the specific subgroups previously receiving immunotherapy, the median PFS of the Telaglenastat+cabotinib group and the placebo+cabotinib group were 11.
    1 months and 9.
    2 months, respectively (HR=0.
    77; 95% CI: 0.
    56, 1.
    06)
    .

    In the placebo+cabotinib group, the median PFS of patients who received immunotherapy was 9.
    2 months, the median PFS of patients who did not receive immunotherapy was 9.
    5 months, and the ORR was 32% and 20%, respectively.
    Including nivolumab + ipilimumab, ORR is 37%
    .

    The incidence of adverse events in the Telaglenastat+cabotinib group was similar to that in the placebo+cabotinib group.
    The incidence of grade 3-4 adverse events was 71% and 79%, including hypertension (17% vs 18%) and diarrhea ( 15% vs 13%)
    .

    Cabozantinib was discontinued in 10% and 15% of patients in the two groups due to adverse events
    .

    Conclusion: The addition of Telaglenastat did not further improve the efficacy of mRCC
    .

    The Telaglenastat+cabotinib combination regimen was well tolerated, and the adverse events were consistent with the known conditions of each single agent
    .

    This study provides valuable efficacy data for mRCC patients receiving cabozantinib in the second or third line
    .

    Clinical trial information: NCT03428217
    .

    Reference: CANTATA: Primary analysis of a global, randomized, placebo (Pbo)-controlled, double-blind trial of telaglenastat (CB-839) + cabozantinib versus Pbo + cabozantinib in advanced/metastatic renal cell carcinoma (mRCC) patients (pts ) who progressed on immune checkpoint inhibitor (ICI) or anti-angiogenic therapies.
