A Study of Ifinatamab Deruxtecan in Pediatric Participants With Relapsed or Refractory Solid Tumors (MK-9999-01D/LIGHTBEAM-U01)
LIGHTBEAM-U01 Substudy 01D: A Phase 1b/2 Substudy to Evaluate the Safety and Efficacy of Ifinatamab Deruxtecan in Pediatric Participants With Relapsed or Refractory Solid Tumors
Researchers are looking for new ways to treat children with relapsed or refractory solid tumors:
- Relapsed means the cancer came back after treatment
- Refractory means the cancer did not respond (get smaller or go away) to treatment
- Solid tumors are cancers mostly in body organs and tissues, not in the blood or other body liquids
The study treatment I-DXd (also known as MK-2400 or ifinatamab deruxtecan) is an antibody-drug conjugate (ADC). An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. The goals of this study are to learn:
- About the safety of I-DXd and if children younger than 12 years old tolerate it
- How many children who receive I-DXd have the cancer get smaller or go away
調査の概要
詳細な説明
This study will have 2 parts: Part 1 will evaluate the safety and tolerability and determine the recommended dose for expansion (RDE) of I-DXd, followed by Part 2 an efficacy expansion.

Part 1 and Part 2: Duration of Response (DOR) For Participants With NBL, RMS, WT, or OST
時間枠:Up to approximately 5 years
|
For participants who demonstrate a confirmed CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until PD or death. PD is defined as at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. Note: The appearance of one or more new lesions is also considered PD. DOR as assessed by the investigator will be presented. |

SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm). Note: The appearance of one or more new lesions is also considered PD. The time from the first dose until the date of SD must be greater than or equal to 6 weeks.
