    Professor Cheng Ying: Phase I study of dose escalation and dose amplification of Lurbinectedin in the treatment of advanced solid tumors


    This is a single-arm, open-label, multicenter, multiple-dose, dose-escalation and dose-expanded Phase I clinical trial conducted in China to evaluate the safety, tolerability, pharmacokinetic (PK) profile and preliminary efficacy
    of Lurbinectedin in Chinese patients with advanced solid tumors, including recurrent small cell lung cancer (SCLC).
    The study consisted of two phases, the first dose-escalation phase aimed to determine the dose-limiting toxicity and recommended dose
    of Lurbinectedin monotherapy in patients with advanced solid tumors in China.
    The subsequent expansion phase is to apply the established recommended dose to patients with recurrent SCLC after failure of first-line platinum-based chemotherapy to evaluate indicators such as
    the efficacy and safety of Lurbinectedin in this population 。 The results suggest that the efficacy of Lurbinectedin in Chinese patients with recurrent SCLC who have failed first-line platinum-containing chemotherapy is comparable with the efficacy results of the SCLC cohort of the foreign phase II basket trial, with a better overall response rate (ORR: 45.
    5% vs 30.
    5%), and tends to have a better survival benefit (mPFS: 5.
    6 months vs 3.
    5 months, mOS: 11.
    0 months vs 9.
    3 months; IRC assessment, data immature).

    The safety and tolerability of Lurbinectedin in Chinese groups were generally acceptable, and the PK characteristics of Chinese groups were similar
    to those in European and American populations.


    Professor Duan Jianchun: Phase Ib clinical study of YK-029A in the treatment of treatment-naïve patients with EGFR ex20ins mutation in late NSCLC


    This study is a multicenter, open-label, phase I registration clinical trial (clinical trial approval: 2018L02052), with a total of 15 cases enrolled in cohort 1 (treatment, 150mg, QD), 10 cases in cohort 2 (treatment, 200mg, QD) and 28 cases in cohort 3 (treatment-naïve, 200mg, QD), with the primary endpoint ORR and secondary endpoints including PFS, DOR, DCR and safety
    。 The results showed that in this preliminary analysis of the early study, YK-029A tablets significantly improved the ORR (68.
    4%) of NSCLC patients with treatment-naïve EGFR ex20ins mutation, with a DCR of 94.
    7% and a 6-month DOR rate of 64.

    At the cut-off time of data, median DOR and median PFS were not achieved at a median follow-up of 7.
    3 months, indicating a lasting benefit and a manageable
    safety profile.
    Most participants had a good benefit after receiving YK-029A tablets and were not limited
    by the presence or absence of brain metastases, type of EGFR ex20ins mutation, and location of insertion of EGFR ex20in mutations.
    In addition, based on the data results of the phase Ib 20ins-naïve cohort, YK-029A tablets have been certified
    as breakthrough therapies by NMPA.


    Professor Yuan Shuanghu: Stratified risk and prognosis of pIIIA-N2 non-small cell lung cancer with radical resection


    In this review, patients with pIIIA-N2 non-small cell lung cancer who had radical resection were retrospectively included, and all patients underwent adjuvant chemotherapy or chemoradiotherapy according to the clinical situation, and the main indicators were the positive rate of NGS at postoperative margins, disease-free survival (DFS) and overall survival (OS).

    This study explored whether the detection of minimal residual lesions (MRD) in surgical margin tissue can be used as a stratified marker for recurrence risk and prognosis of pIIIA-N2 non-small cell lung cancer with radical resection
    The results suggest that the NGS test results can be used as a supplement to the pathological R0 detection, and the DFS and OS of postoperative patients with positive molecular margins are significantly lower than those in negative patients (p<0.
    05), and postoperative molecular margin status is an independent predictor of recurrence risk in postoperative patients, and patients with positive molecular margins may suggest a new treatment strategy to replace adjuvant therapy

    Professor Zhang Jian: DZD1516, a highly selective HER2 tyrosine kinase inhibitor that can completely penetrate the blood-brain barrier, preliminary data of non-clinical studies and phase I clinical studies


    DZD1516 is an oral, highly effective, reversible and selective HER2 TKI
    that fully penetrates the blood-brain barrier.
    In animal models, DZD1516 was able to inhibit tumor growth in both HER2-expressing BT474c1 mouse brain metastases and subcutaneous models, and the efficacy was dose-related.
    In the HER2-high expression BT474c1 mouse brain metastasis model, DZD1516 combined with T-DXd had a synergistic anti-tumor effect
    In clinical trials that included patients with HER2-positive advanced breast cancer with or without central nervous system metastases who had failed or were intolerant to standard therapy, the aim was to assess the safety and tolerability of DZD1516 and determine the maximum tolerable dose (if possible).

    The results suggest that DZD1516 has good safety and tolerability, and no adverse events (such as diarrhea, rash, etc.
    ) associated with wild-type EGFR suppression have been reported at MTD and below doses
    DZD1516 has good pharmacokinetic properties and excellent blood-brain barrier permeability, and the combined systemic exposure of DZD1516 and DZ2678 increases
    with dose increase in the dose range of 50mg-250mg.
    In patients with brain metastases, the Kpuu and CSF (arithmetic mean) of DZD1516 and DZ2678 were 2.
    1 and 0.
    , respectively.
    DZD1516 may provide a new treatment option for patients with HER2-positive breast cancer, and follow-up clinical studies are planned

    Professor Guo Jun: Recombinant human GM-CSF oncolytic herpes simplex virus type II (OH2) injection monotherapy or in combination with HX008 in the treatment of patients with inoperable advanced melanoma: an open-label phase I study


    Oncolytic viruses are a class of viruses
    that are natural or genetically edited to specifically replicate in tumor cells and exert anti-tumor effects.
    OH2 was genetically modified to delete the neurotoxic factor ICP34.
    5 to promote selective replication of the virus in tumor cells and enhance safety; the virulence gene ICP47 was deleted, which reduced immunosuppression, promoted viral replication and enhanced anti-tumor efficacy; GM-CSF was inserted to induce a stronger, durable and specific anti-tumor immune response
    The results of the clinical study of OH2 injection alone or in combination with HX008 in the treatment of unresectable advanced melanoma showed that in terms of safety, the common adverse reaction was fever and no DLT; The severity of adverse reactions in the single-agent group was grade 1/2, and the acute pancreatitis in the combined group was grade 3 (cured); During the clinical trial, no biosafety problems
    such as virus shedding occurred.
    In terms of efficacy, a trend towards survival benefit was observed, particularly in the subgroup of populations who failed PD-1 treatment and had disease stage III-IVM1a
    In the OH2 injection monotherapy group, the median follow-up time was 19.
    6 months, mOS was not achieved, ORR was 21.
    6%, and DCR was 56.

    The ORR of 8 participants who had previously failed PD-1 treatment and had disease stage III-IVM1a was 62.


    Professor Li Ning: PRIME study: Efficacy and safety of maintenance therapy with niraparib individualized starting dose for newly diagnosed advanced ovarian cancer, a randomized, double-blind, placebo-controlled, phase III trial


    The PRIME study is a randomized, double-blind, placebo-controlled, phase III trial (NCT03709316) designed to prospectively evaluate the efficacy and safety of an individualized starting dose of niraparib as maintenance therapy for first-line platinum-based chemotherapy remission in patients with newly diagnosed advanced ovarian cancer, regardless of
    biomarkers and postoperative residual disease status 。 The PRIME study prospectively demonstrated a statistically significant and clinically significant
    benefit of niraparib as first-line maintenance therapy for newly diagnosed advanced ovarian cancer, regardless of biomarker status and postoperative residual disease status.
    Although OS data were not yet mature, a trend of
    benefit in the niraparib group was observed at data cut-off.
    All patients were prospectively given an individualized starting dose, and the safety profile of niraparib improved
    The PRIME data again confirm that niraparib monotherapy maintenance is the standard of care after first-line platinum-containing chemotherapy, regardless of
    biomarker status.
