Drug Repurposing in Thyroid Carcinoma: a Feasibility Trial (REPOTHYROID-II)

August 31, 2026 updated by: Radboud University Medical Center

Network Pharmacology-based Personalized Drug Repurposing in Thyroid Carcinoma: a Pilot Feasibility Trial

This is a phase Ib trial that studies personalized network pharmacology-based drug repurposing in patients with advanced thyroid cancer who have no other treatment options. The main objective is to study if it is feasible to give patients individualized drug combinations selected based on their tumor genetic profile. The secondary objective is to find out whether these treatments are safe and can help control the growth of the patient tumors or stop them from getting worse.

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

Patients with advanced thyroid cancer often have very few treatment options, and standard therapies usually cannot cure the disease. Some types grow and spread quickly and do not respond to surgery and radioactive iodine. For patients with other types, existing drugs may slow the disease but can cause strong side effects, limiting their usefulness.

This study is testing a new personalized approach called network pharmacology-based drug repurposing. This concept uses genetic tumor information to identify combinations of existing approved drugs that may work better together. The idea is that targeting several connected networks in the tumor at the same time may be more effective than standard treatments that focus on a single target.

The main objective is to study if it is feasible to give patients individualized drug combinations selected based on their tumor genetic profile. The secondary objective is to find out whether these treatments are safe and can help control the growth of the patient tumors or stop them from getting worse.

This is an exploratory, single-arm phase Ib trial. Each patient receives a personalized treatment based on the genetic profile of their tumor. The study focuses on understanding feasibility and safety. Each participant will be in the study for approximately 4 months. The first month is used to examine the tumor of the patient and select the best personalized treatment. Once the treatment is chosen and both the patient and their doctor agree, the patient will receive the treatment for three months. During treatment, patients will have regular check-ups, blood tests, scans, and questionnaires to monitor safety and see how well the treatment is controlling the tumor.

This study is funded by the EU horizon project Precision drug REPurpOsing For EUrope and the world (REPO4EU) under grant agreement No. 101057619

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • Measurable disease per RECIST 1.1
  • ECOG performance status ≤ 2

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Personalized network-pharmacology-based combination therapy
Patients with advanced thyroid cancer undergo tumor molecular profiling using to identify personalized drug repurposing treatments. All drugs are administered at authorized therapeutic doses according to the summary of product characteristics. Treatment regimens vary between patients depending on the identified molecular profile.
Combination product: Personalised treatment
The therapy will consist of (one or more) approved drugs.
