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

Part 1: Dose escalation and expansion of APG-115 monotherapy in pediatric neuroblastoma or solid tumors to determine MTD and recommended phase 2 dose, RP2D.

Part 2: Dose escalation of APG-2575 to determine the MTD and RP2D combined with APG-115 at the dose level determined in part 1 in pediatric neuroblastoma or solid tumor, and extend the RP2D level of the combination therapy.

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

12 years to 18 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

  3. Physical state score ≥ 50.
  4. Expected survival ≥ 3 months.
  5. There are target lesions (neuroblastoma) or measurable lesions (other solid tumors).
  6. Have adequate organ function.
  7. Fresh or archived tumor tissue samples should be provided prior to treatment. If none of these specimens are available, inclusion may be made after consultation with the sponsor.

  11. The ability to swallow research drugs.

Exclusion Criteria:

  1. Received biological therapy, chemotherapy, or other investigational drugs within 21 days prior to dosing.
