产品描述

Avanbulin (BAL27862) is a potent, Colchicine site-binding, tubulin assembly inhibitor. Avanbulin inhibits tubulin assembly at 37 °C with an IC50 of 1.4 μM. Avanbulin binds to tubulin with an apparent Kd value of 244 nM. Avanbulin can be used for the research of cancer and cell division[1][2][3][4].

Avanbulin (0-4 μM) binds to tubulin with an apparent Kd value of 244 nM[1].Avanbulin (0-20 μM) and Colchicine (0-10 μM) are competitive for binding to tubulin with an apparent Ki value of 1.8 μM[1].Avanbulin binds to the same site as Colchicine at the intradimer interface[1].Avanbulin (50 μM; 0, 10, 20, 30, 60 min) induces the proteolysis of tubulin[1].Avanbulin (1-100 nM; 72 h; HeLa-tubGFP cells) has anti-proliferative effects[1].Avanbulin (33 nM; 0, 10, 20, 30, 60 min; HeLa-tubGFP cells) collapses the mitotic spindle and forms the tiny tubulin aggregates[1].Avanbulin does not induce the formation of tubulin oligomers[1].Avanbulin (0.1 nM-1.0 μM; 96 hours) induces growth inhibition of cells with a median relative IC50 of 13.8 nM[2].Avanbulin (0-1,000 nM; 3 days) inhibits the growth of glioblastoma cancer stem-like cells, GBM6 (EC50=20.8 nM) and GBM9 (EC50=21.7 nM) [3].Avanbulin (6 nM and 20 nM) inhibits the migration of GBM6 and GBM9 cells[3].Avanbulin (6 nM and 20 nM; GBM6-shEB1 and GBM6-sh0 cells) triggers astrocytic differentiation of GBM6 in an EB1-dependent manner[3].Avanbulin (12 nM; 4 h) reduces kinetochore-microtubule (KT-MT) occupancy of MG132(10 μM; 2h) treated hTert-RPE1 eGFP-α-tubulin cells[4].Avanbulin (12 nM; 4 h) reduces average inter-KT distances of cells[4].Avanbulin-treated (12 nM; 4 h) cells show intact spindle morphology and lack of obvious chromosome alignment defects[4].

Phase 1/2a trial of intravenous BAL101553, a novel controller of the spindle assembly checkpoint, in advanced solid tumours

Br J Cancer 2020 Oct;123(9):1360-1369.PMID:32741975DOI:10.1038/s41416-020-1010-8.

Background: BAL101553 (lisavanbulin), the lysine prodrug of BAL27862 (Avanbulin), exhibits broad anti-proliferative activity in human cancer models refractory to clinically relevant microtubule-targeting agents. Methods: This two-part, open-label, phase 1/2a study aimed to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of 2-h infusion of BAL101553 in adults with advanced or recurrent solid tumours. The MTD was determined using a modified accelerated titration design in phase I. Patients received BAL101553 at the MTD and at lower doses in the phase 2a expansion to characterise safety and efficacy and to determine the recommended phase 2 dose (RP2D). Results: Seventy-three patients received BAL101553 at doses of 15-80 mg/m2 (phase 1, n = 24; phase 2a, n = 49). The MTD was 60 mg/m2; DLTs observed at doses ≥60 mg/m2 were reversible Grade 2-3 gait disturbance with Grade 2 peripheral sensory neuropathy. In phase 2a, asymptomatic myocardial injury was observed at doses ≥45 mg/m2. The RP2D for 2-h intravenous infusion was 30 mg/m2. The overall disease control rate was 26.3% in the efficacy population. Conclusions: The RP2D for 2-h infusion of BAL101553 was well tolerated. Dose-limiting neurological and myocardial side effects were consistent with the agent's vascular-disrupting properties.

Safety and anti-tumor activity of lisavanbulin administered as 48-hour infusion in patients with ovarian cancer or recurrent glioblastoma: a phase 2a study

Invest New Drugs 2023 Feb 16.PMID:36792805DOI:10.1007/s10637-023-01336-9.

Lisavanbulin (BAL101553) is the prodrug of Avanbulin (BAL27862), a microtubule-destabilizing agent. The goal of this study (NCT02895360) was to characterize the safety, tolerability and antitumor activity of lisavanbulin administered as a 48-hour intravenous (IV) infusion at the recommended Phase 2 dose (RP2D) of 70 mg/m2. Results from the Phase 1 dose-escalation portion of the study identifying the RP2D have been previously reported. Here, we present the findings from the Phase 2a portion of this study. Methods. This multi-center, open-label study included patients with ovarian, fallopian-tube, or primary peritoneal cancer that was either platinum-resistant or refractory (11 patients), or with first recurrence of glioblastoma (12 patients). Lisavanbulin was administered as a 48-hour IV infusion on Days 1, 8, and 15 of a 28-day cycle. Results. Lisavanbulin was well tolerated in both patient cohorts. Thirteen patients (56.5%) developed 49 adverse events assessed as related to study treatment. The majority were mild or moderate; four were grade 3/4. Sixteen SAEs were reported in nine patients (39.1%), with none considered related to study treatment. No AEs led to permanent treatment discontinuation. Three patients in the ovarian cancer cohort had stable disease with lesion size reductions after two cycles of treatment; in the glioblastoma cohort, one patient showed partial response with a > 90% glioblastoma area reduction as best response, and one patient had stable disease after eight cycles of treatment. Conclusion. This study demonstrated a favorable safety and tolerability profile of 48-hour continuous IV infusion of lisavanbulin in patients with solid extracranial tumors or glioblastoma. Clinicaltrials.gov registration: NCT02895360.
