Detailed Description

Open label, multi center, Phase 1 (dose escalation) and Phase 2a (dose expansion) study design to evaluate safety, tolerability, PK, PD and anti-tumor effects of ALRN-6924, alone or in combination with palbociclib, in patients with advanced solid tumors or lymphomas with wild-type (WT) TP53. ALRN-6924 is a stabilized cell-permeating peptide designed to disrupt the interaction between the p53 tumor suppressor protein and its predominant endogenous inhibitors, murine double minute 2 (MDM2) and murine double minute X (MDMX). The Phase 1 portion of the study will enroll adults with histologically or cytologically confirmed malignancies that are metastatic or unresectable and for which standard treatment(s) are not available or are no longer effective. The Phase 2a portion of the study consists of separate cohorts that will enroll distinct groups of patients with specific solid tumors and/or lymphomas to further investigate the clinical safety profile and potential efficacy of ALRN-6924 alone or in a combination regimen. Treatment will continue until unacceptable toxicity, patient or physician decision to discontinue therapy or disease progression that is either symptomatic, rapidly progressive, requires urgent intervention or is associated with a decline in performance status. Patients with PTCL have been selected as a group to be further studied in Phase 2a. Patients with MDM2-amplified or MDM2/CDK4-co-amplified solid tumors have been selected as another group to be further studied in Phase 2a.
