MGD019 DART® Protein in Unresectable/Metastatic Cancer
|
A Phase 1, First-in-Human, Open-Label, Dose Escalation and Cohort Expansion Study of MGD019, a Bispecific DART® Protein Binding PD-1 and CTLA-4 in Patients With Unresectable or Metastatic Neoplasms
|
The purpose of this study is to evaluate the safety and tolerability, pharmacokinetics (PK) pharmacodynamics and preliminary antitumor activity of lorigerlimab.
This Phase 1, open-label study will characterize safety, dose-limiting toxicities (DLTs), and maximum tolerated/administered dose (MTD/MAD) of MGD019. Dose escalation will occur in a 3+3+3 design in patients with advanced solid tumors of any histology. Once the MTD/MAD is determined, a Cohort Expansion Phase will be enrolled to further characterize safety and initial anti-tumor activity in patients with specific tumor types anticipated to be sensitive to dual checkpoint blockade.

Inclusion Criteria:
Exclusion Criteria:
- In patients who have previously received an immune checkpoint inhibitor (e.g., anti-PD-L1, anti-PD-1, anti-CTLA-4), toxicities related to the checkpoint inhibitor must have resolved to ≤ Grade 1 or baseline. Patients with well controlled immune endocrinopathies secondary to prior checkpoint therapy are eligible.
- Patients with symptomatic CNS metastases. Patients with history of prior CNS metastasis must have been treated, must be asymptomatic, and must not have concurrent treatment for the CNS disease, progression of CNS metastases on magnetic resonance imaging (MRI) or computed tomography (CT) for at least 14 days after last day of prior therapy for the CNS metastases, or concurrent leptomeningeal disease or cord compression.
- Patients who sustained the following Grade 3 immune checkpoint inhibitor related AEs are ineligible: Ocular AE, changes in liver function tests that met the criteria for Hy's law (> 3 × ULN of either ALT or AST with concurrent > 2 × ULN of total bilirubin and without alternate etiology), neurologic toxicity, colitis, renal toxicity, pneumonitis.
- Patients who have received prior therapy with a combination of monoclonal antibodies against PD-1/PD-L1 and CTLA-4 will be excluded in the Cohort Expansion (this does not apply to the melanoma expansion cohort).
- Patients with any history of known or suspected autoimmune disease with certain exceptions
- History of prior allogeneic bone marrow, stem-cell, or solid organ transplantation.
- History of trauma or major surgical procedure within 4 weeks prior to initiation of study drug administration.
- Systemic antineoplastic therapy, or investigational therapy (for all tumor types) or androgen receptor antagonist/androgen synthesis inhibitor for mCRPC (e.g., enzalutamide or abiraterone, respectively) within the 4 weeks prior to initiation of study drug administration.
- Treatment with radiation therapy within 2 weeks prior to initiation of study drug administration.
- Radioligand (e.g., radium-223) within 6 months prior to initiation of study drug administration for mCRPC in the Cohort Expansion Phase.
- Serum testosterone > 50 ng/dl or > 1.7 nmol/L for mCRPC in the Cohort Expansion Phase.
- Confirmed or presumed COVID-19/SARS-CoV-2 infection. While SARS-CoV-2 testing is not mandatory for study entry, testing should follow local clinical practice guidelines/standards. Patients with a positive test result for SARS-CoV-2 infection, known asymptomatic infection, or presumed infection are excluded. Patients may be considered eligible after a resolved SARS-CoV-2 infection once he or she remains afebrile for at least 72 hours and after other SARS-CoV-2-related symptoms have fully recovered to baseline for a minimum of 72 hours
