A Dose Escalation Study of FP-045 in Patients With Fanconi Anemia

March 4, 2025 updated by: Foresee Pharmaceuticals Co., Ltd.

A Multinational, Multicenter, Dose Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Activity of FP 045 in Patients With Fanconi Anemia (FusuciA Study)

This is a multi-center, Phase 1/2 study to determine the Optimal Biologic Dose (OBD) and to evaluate the safety, tolerability, PK, and preliminary activity of FP 045 when administered orally in young adult/adolescent and pediatric patients with Fanconi anemia. The study will enroll a total of 4 young adult/adolescent patients and a minimum of 8 and up to 12 pediatric patients with mild-moderate bone marrow failure who have not undergone hematopoietic cell transplant. This makes the total patient number between 12-16 total. Dose escalation will occur individually for each patient, within each age group. Each patient will receive each of 3 dose levels of FP 045 (intra-patient dose escalation), beginning with Dose Level 1, followed by Dose Levels 2 and 3. Each dose level will be administered for 28 days prior to escalation to the next higher dose level for that patient.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

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

Dose escalation will begin with young adult/adolescent patients. The initial two patients enrolled in the study will be > 15 years of age. These patients must complete the entire 28-day period of treatment at Dose Level 1 prior to additional young adult/adolescent patients being enrolled. All 4 young adult/adolescent patients must complete 28 days of treatment at Dose Level 1, and cumulative safety must be reviewed by the Safety Review Committee (SRC), prior to the enrollment of pediatric patients. The initial two pediatric patients enrolled will be > 6 years of age. These patients must complete the entire 28-day period of treatment at Dose Level 1 prior to additional pediatric patients being enrolled. A minimum of 8 and maximum of 12 pediatric patients will be enrolled to allow for at least 4 patients between the ages of 3-6.

Study assessments will be conducted at each visit. Patients will be observed closely for Dose Limiting Toxicity (DLT) during each dosing period. Any patient experiencing a DLT will have study drug interrupted and will not be allowed to escalate to the next higher dose level. The patient may resume treatment at one dose level lower once the DLT has resolved to baseline or to ≤ Grade 1 in severity. The MTD will be defined as the dose level immediately below the dose level at which DLT occurred. Patients requiring an interruption in treatment of > 3 weeks following a DLT will be withdrawn from the study. The MTD will be assessed separately for each individual patient.

Following the completion of dose escalation, each patient will continue treatment at either the highest dose or their individual MTD, and then transition to the OBD for their age group (once defined), for a total of 3 months. Patients failing to receive 75% of planned doses for reasons other than adverse effects may be replaced.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

5 months to 21 years (Child, Adult)
