APG-115 in Salivary Gland Cancer Trial

July 10, 2026 updated by: University of Michigan Rogel Cancer Center

A Multicenter Phase I/II Trial of a Novel MDM2 Inhibitor (APG-115) in p53 Wild-type Salivary Gland Carcinoma

This is a phase I/II trial to evaluate the efficacy of APG-115 +/- Carboplatin for the treatment p53 wild-type malignant salivary gland cancer.

Part 1 consisted of 2 arms, arm A (APG-115 monotherapy) and arm B (APG-115 + Carboplatin) and was terminated early.

Part 2 is a single arm study (APG-115 monotherapy).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The current single arm study design was originally part of a study with a parallel arm given combination APG-115 + Carboplatin. In the initial phase of that previous iteration, the combination arm was closed early for issues related to tolerability of the combination therapy. This study will continue as a single arm, monotherapy alone, Phase I/II study as approved by the UM Institutional Review Board as of June 2021.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 1
  • Presence of measurable disease by CT scan per RECIST v1.1 with ≥ 20% increase in tumor burden in the preceding 12 months
  • Life expectancy of ≥12 weeks
  • Signed and dated informed consent document indicating that the patient (or legally acceptable representative) has been informed of all pertinent aspects of the trial prior to enrollment

Exclusion Criteria:

  • Prior treatment with MDM2 inhibitors

Patients with a history of treated CNS metastases are eligible provided they meet all of the following criteria: disease outside the CNS is present, no clinical evidence of progression since completion of CNS-directed therapy, minimum 4 weeks between completion of radiotherapy and enrollment, and recovery from significant (Grade ≥ 3) acute toxicity.
  • A serious uncontrolled medical disorder or active infection that would impair their ability to receive study treatment

Arms and Interventions

Participant Group / Arm

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary Toxicity Endpoint: dose-limiting toxicity (DLT)
Time Frame: 42 days
DLT will be defined based on the rate of drug-related grade 3-5 adverse events experienced within the first 6 weeks (2 cycles) of study treatment. These will be assessed via CTCAE version 5.0
42 days
Maximally tolerated dose (MTD)
Time Frame: 42 days
MTD will be determined based on DLTs observed during the first 6 weeks (2 cycles) of study treatment.
42 days
Overall response rate
Time Frame: up to 12 months
Overall response rate will be defined as the proportion of patients achieving either complete response (CR) or partial response (PR). Response will be assessed via RECIST v1.1.
up to 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall response rate by tumor histology
Time Frame: Until death or end of study; up to approximately 5 years
Overall response rate will be defined as the proportion of patients achieving either complete response (CR) or partial response (PR), assessed via RECIST v1.1 and reported separately for those with histologically confirmed adenoid cystic carcinoma (ACC) versus other malignant salivary gland tumors (non-ACC)
Until death or end of study; up to approximately 5 years
Duration of response
Time Frame: Until death or end of study; up to approximately 5 years
The duration of overall response is measured from the time measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started). Stable disease is measured from the start of the treatment until the criteria for progression are met, taking as reference the smallest measurements recorded since the treatment started.
Until death or end of study; up to approximately 5 years
Progression-free survival
Time Frame: Until death or end of study; up to approximately 5 years
Progression-free survival (PFS) is defined as the duration of time from start of treatment to time of progression or death, whichever is earlier.
Until death or end of study; up to approximately 5 years
Overall survival
Time Frame: Until death or end of study; up to approximately 5 years
Overall survival (OS) is defined as the duration of time from start of treatment to time of death or end of study.
Until death or end of study; up to approximately 5 years
Disease control rate
Time Frame: Until death or end of study; up to approximately 5 years
Defined as the proportion of patients achieving complete response (CR), partial response (PR), or stable disease (SD). Response will be assessed via RECIST v1.1
Until death or end of study; up to approximately 5 years
