ALRN-6924 in Patients With Advanced Solid Tumors or Lymphomas

Aileron Therapeutics, Inc.142 enrolled

Overview

This study evaluates the anti-tumor effects of ALRN-6924 in patients with advanced solid tumors or lymphomas with WT TP53.

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.

Outcomes

Primary Outcomes

Evaluate the Safety and Tolerability of ALRN-6924 in Adult Patients With Advanced Solid Tumors or Lymphomas With Wild-type (WT) TP53 Who Are Refractory to or Intolerant of Standard Therapy, or for Whom no Standard Therapy Exists

Number of participants with treatment-related adverse events as assessed by CTCAE v.4.0

Time frame: From Day 1 of treatment until 30 days after the last cycle of treatment (each cycle in DR-A is 28 days, DR-B and DR-C is 21 days), an average of 138 Days

Time frame: From Day 1 of treatment until 30 days after the last cycle of treatment (each cycle in DR-A is 28 days, DR-B and DR-C is 21 days), an average of 138 Days

Determine the Maximum Tolerated Dose (MTD) of ALRN-6924 in Adult Patients With Advanced Solid Tumors or Lymphomas

Determine the maximum tolerated dose (MTD)

Time frame: From Day 1 of treatment until 30 days after the last cycle of treatment (each cycle in DR-A is 28 days, DR-B and DR-C is 21 days), an average of 138 Days

Determine Overall Response Rate

The proportion of efficacy-evaluable patients who achieve complete response (CR) or partial response (PR), per investigator assessment, in accordance with RECIST 1.1 or iRECIST (for solid tumor patients) or Response Assessment in Neuro-Oncology (RANO) criteria (for glioblastoma patients).

Time frame: From Day 1 of treatment until 30 days after the last cycle of treatment (each cycle in DR-A is 28 days, DR-B and DR-C is 21 days), an average of 138 Days

Secondary Outcomes

Assess Additional Measures of Anti-tumor Activity, Including Duration of Response, Progression Free Survival, Overall Survival and Time to Response
