1052 Background: Following promising outcomes in hormone receptor (HR)-positive, HER2-negative endocrine-resistant advanced breast cancer (BC) with lerociclib plus fulvestrant, this study assesses the efficacy and safety of lerociclib and letrozole in HR+/HER2- advanced or metastatic BC. Methods: This randomized, double-blind, placebo-controlled phase III study involved HR+/HER2- advanced or metastatic BC patients without prior systemic therapy for advanced disease. Participants were allocated 1:1 to either lerociclib (150mg twice daily) with letrozole or placebo with letrozole. The primary endpoint was progression-free survival (PFS) as assessed by investigators. Secondary endpoints included PFS (assessed by Blinded Independent Central Review (BICR)), response rates, overall survival (OS), and safety. The interim analysis was planned approximately 80 PFS events. Results: By September 20, 2023, 279 patients were randomized (137 to lerociclib + letrozole, 142 to placebo + letrozole), with a median follow-up of 12.91 months. Baseline characteristics were comparable across groups. At the data cutoff, 83 PFS events were reported. The lerociclib significantly improved PFS versus placebo (median: not reached (NR) versus 16.56 months; hazard ratio: 0.464; 95% CI: 0.293-0.733; p=0.0004). BICR analysis confirmed these results (median: NR versus NR; hazard ratio: 0.457; 95% CI: 0.274-0.761; p=0.0011). Subgroup benefits were consistent, including in patients with visceral metastases, extensive metastatic sites and previous (neo)adjuvant endocrine therapy, etc. For patients with measurable disease, lerociclib plus letrozole showed a higher objective response rate (62.3%) compared to placebo group (48.5%). OS data were immature at the cutoff. Adverse events were primarily hematological toxicity, with higher incidences of grade 3/4 neutropenia (grade 3: 41.6% vs. 0.7%; grade 4: 5.1% vs. 0%) and leucopenia (grade 3: 27.0% vs. 0%; grade 4: 1.5% vs. 0%) in the lerociclib group. All of neutropenia and leukopenia were considered to be treatment related. Grade 3 diarrhea was infrequent, only 1 case (0.7%) was reported in lerociclib group. QTc prolongation was reported comparable between lerociclib group (4.4%, Grade 3:1.5%) and placebo group (3.5%, Grade 3:0.7%). No venous thromboembolism was reported. Serious AEs were slightly higher in the lerociclib group (13.1% vs. 7.7%). Treatment discontinuation due to AEs was rare (1 patient [0.7%]) with lerociclib. Conclusions: Lerociclib with letrozole had an excellent safety profile and significantly prolonged PFS in HR+/HER2- advanced or metastatic BC patients. This benefit was consistent across all clinically relevant subgroups, suggesting lerociclib as a viable first-line therapeutic option with a favorable benefit-risk balance.

BACKGROUND AND OBJECTIVEGB221 is a recombinant humanized anti-HER2 monoclonal antibody. The purpose of this study was to evaluate the pharmacokinetic, safety, and immunogenicity of GB221 in healthy Chinese adults in comparison to trastuzumab (Herceptin^®).METHODSIn this randomized, double-blind, parallel-group phase I clinical trial, 88 subjects were randomized 1:1 to receive a single intravenous infusion (90-100 min) of GB221 or trastuzumab (6 mg/kg). The primary pharmacokinetic parameters-maximum observed serum concentration (C_max), area under the serum concentration-time curve from zero to the last quantifiable concentration at time t (AUC_0-t), and area under the serum concentration-time curve from time zero to infinity (AUC_0-∞)-of GB221 and trastuzumab were compared to establish whether the 90% confidence interval (CI) attained the 80-125% bioequivalence standard. Safety and immunogenicity were also evaluated.RESULTSThe GB221 group (n = 43) and the trastuzumab group (n = 44) showed similar pharmacokinetic characteristics. The geometric mean ratios (90% CI) of C_max, AUC_0-t, and AUC_0-∞ between the two groups were 107.53% (102.25-113.07%), 108.31% (103.57-113.26%), and 108.34% (103.57-113.33%), respectively. The incidence of treatment-emergent adverse events (TEAEs) was 83.7% (36/43) of the subjects in the GB221 group and 95.5% (42/44) of the subjects in the trastuzumab group. No subjects withdrew from the trial due to TEAEs, and there were no occurrences of serious adverse events. All subjects tested negative for antidrug antibodies (ADA).CONCLUSIONGB221 demonstrated similar pharmacokinetics to trastuzumab and comparable safety and immunogenicity in healthy Chinese adults.

Abstract LB128: A novel tri-specific T cell engager targeting BCMA and GPRC5D for treatment of multiple myeloma

AbstractIntroductionMultiple myeloma (MM) accounts for 10% of all hematologic cancers. Recent advances in MM therapy have greatly increased the overall response and survival rate. However, almost all patients eventually relapse. The prognosis still remains poor. BCMA and GPRC5D are overexpressed in myeloma cells. Although CAR-T and T cell engager (TCE) targeting BCMA or GPRC5D have been efficacious in MM patients, resistance does occur. Since the expression of BCMA and GPRC5D in MM are heterogeneous, to further improve the overall response and survival, we have recently generated a novel tri-specific T-cell engager, GBD218, targeting both BCMA and GPRC5D. GBD218 has demonstrated potent in vitro and in vivo activity against myeloma cells.MethodsAnti-BCMA and GPRC5D nanobodies were screened from alpaca immune libraries, and anti-CD3 antibody was engineered from mouse hybridoma clone. The tri-specific antibodies were constructed in a “1+1+1” format through “knob into hole” technology fused with silenced IgG1 Fc. The format of the tri-specific antibodies was optimized by multiple rounds of in vitro activity and druggability evaluation. The in vivo tumor growth inhibition effects were evaluated in PBMC-humanized xenograft mouse models.ResultsGBD218 has been designed to potently bind hBCMA (KD=0.4nM) and hGPRC5D (cell binding EC50 ~ 2nM). To reduce CRS and other potential AEs associated with TCEs, a low affinity of anti-CD3 Fab was used. In cell-based functional assays, GBD218 showed efficient cytotoxicity against single and double positive MM cell lines with various expression levels of BCMA and GPRC5D. T cell activation and cytokine release induced by GBD218, in the presence or absence of MM cancer cells, is nicely balanced for great killing efficacy and the low risk of CRS. Importantly, the results showed that GBD218 exhibited superior in vitro killing activity compared to benchmarks, including teclistamab, talquetamab, the combination of teclistamab and talquetamab, suggesting a synergistic effect of GBD218 by targeting BCMA and GPRC5D. In xenograft models, GBD218 showed excellent anti-tumor activity, indicating great potential for GBD218 as a promising therapeutics for MM.ConclusionGBD218 is a novel tri-specific antibody that showed potent in vitro and in vivo anti-tumor activity. GBD218 efficiently kills both BCMA and/or GPRC5D expressing MM cells, which may hold promise to increase response rate and improve survival in MM patients in clinic.Citation Format: Yongcong Tan, Xuezhen Li, Fan Yu, Juehua Xu, Zhen Qian, Yiqi Cao, Xueyan Yang, Qinglin Du, Fei Peng, Shuhua Han, Qian Ding.
