Brightline-2: a phase IIa/IIb trial of brigimadlin (BI 907828) in advanced biliary tract cancer, pancreatic ductal adenocarcinoma or other solid tumors. (PubMed, Future Oncol)
Brigimadlin (BI 907828) is a highly potent MDM2-p53 antagonist that has shown promising activity in preclinical and early-phase clinical studies. This manuscript describes the rationale and design of an ongoing phase IIa/IIb Brightline-2 trial evaluating brigimadlin as second-line treatment for patients with advanced/metastatic BTC, PDAC, lung adenocarcinoma, or bladder cancer.

Delivery versus potency in treating brain tumors: BI-907828, a MDM2-p53 antagonist with limited BBB penetration but significant in vivo efficacy in glioblastoma. (PubMed, Mol Cancer Ther)
These studies show that efficacy of BI-907828 in orthotopic models is related to high potency even though its CNS distribution is limited by BBB efflux. Therefore, a comprehensive understanding of all aspects of the "Delivery - Potency - Efficacy" relationship is warranted in drug discovery and development, especially for treatment of CNS tumors.

LONGITUDINAL MUTATIONAL ANALYSIS OF TP53 IN CIRCULATING TUMOR DNA IN THE PLASMA OF PATIENTS WITH LIPOSARCOMA IN A PHASE I STUDY OF BRIGIMADLIN (BI 907828), AN MDM2-P53 ANTAGONIST (CTOS 2023)
This mutation analysis represents one of the most robust assessments of longitudinal ctDNA by NGS for TP53 from an MDM2–p53 antagonist trial in liposarcoma. While acquired mutations in TP53 are very common, these data suggest that brigimadlin does not systematically lead to broad acquisition of resistance by inducing alterations in TP53.

The MDM2-p53 antagonist BI 907828 in patients with advanced or metastatic solid tumors: results of a phase Ia, first-in-human, dose-escalation study. (PubMed, Cancer Discov)
As evidence of target engagement, time- and dose-dependent increases in GDF-15 levels were seen. Preliminary efficacy was encouraging (11.1% overall response and 74.1% disease control rates), particularly in well-differentiated or dedifferentiated liposarcoma patients (100% and 75% disease control rates, respectively).

MDM2 Inhibition in the Treatment of Glioblastoma: From Concept to Clinical Investigation. (PubMed, Biomedicines)
While some MDM2 inhibitors have progressed to early phase clinical trials in GBM, their efficacy, alone and in combination, is yet to be confirmed. In this article, we present an overview of MDM2 inhibitors currently under preclinical and clinical investigation, with a specific focus on the drugs being assessed in ongoing clinical trials for GBM patients.

A phase I dose-escalation and expansion study evaluating the safety and efficacy of the MDM2–p53 antagonist brigimadlin (BI 907828) in patients (pts) with solid tumours (ESMO 2023)
Conclusions BI 907828 demonstrated antitumour activity and a manageable safety profile in pts with advanced solid tumours, including those with BTC; dose expansion is ongoing. BI 907828 is being further assessed in pts with BTC in the phase IIa/IIb open-label Brightline-2 trial (NCT05512377).

Brightline-1: phase II/III trial of the MDM2-p53 antagonist BI 907828 versus doxorubicin in patients with advanced DDLPS. (PubMed, Future Oncol)
BI 907828 has shown promising activity in preclinical studies and in a phase Ia/Ib study in patients with solid tumors, particularly those with DDLPS. This manuscript describes the rationale and design of an ongoing multicenter, randomized, phase II/III trial (Brightline-1; NCT05218499) evaluating BI 907828 versus doxorubicin as first-line treatment for advanced DDLPS.

Currently, ten patients with BTC had received BI 907828 ± ezabenlimab (an immune checkpoint inhibitor). The final primary analysis will be performed after all treated patients have been followed for ≥12 weeks, or until study discontinuation. As of February 2023, 16 patients have been enrolled.Clinical trial identification: NCT05512377.Editorial acknowledgement: Medical writing assistance, funded by Boehringer Ingelheim, was provided by Jim Sinclair, PhD, of Ashfield MedComms, an Inizio Company, during the preparation of this abstract.Legal entity responsible for the study: Boehringer Ingelheim.

PHASE IA/IB, DOSE-ESCALATION/EXPANSION STUDY OF THE MURINE DOUBLE MINUTE 2–TUMOR PROTEIN 53 ANTAGONIST BI 907828 IN COMBINATION WITH IMMUNE CHECKPOINT INHIBITORS IN PATIENTS WITH ADVANCED SOLID TUMORS (CTOS 2022)
This Phase Ia/Ib study (NCT03964233) is assessing BI 907828, an MDM2–p53 antagonist, combined with immune checkpoint inhibitors in TP53 wild-type cancers. In Phase Ia (dose escalation), patients with advanced/metastatic solid tumors received escalating doses of BI 907828 guided by a Bayesian Logistic Regression Model (starting dose 10 mg orally) plus ezabenlimab 240 mg (anti-PD-1 antibody) and BI 754111 600 mg (anti-LAG-3 antibody) every 21 days (q3w). The doublet combination of BI 907828 plus ezabenlimab showed a manageable safety profile and early signs of anti-tumor activity. Eleven patients remain on treatment; recruitment is ongoing.
