Solid Malignant TumorsPhase 2NCT06246643
A Study of Continued Treatment With Regorafenib in Participants With Solid Tumors Who Have Participated in Other Bayer Studies
A Phase 2 study testing Regorafenib (Stivarga, BAY73-4506) in people with Solid Malignant Tumors, run by Bayer at 7 sites in 5 countries.
Trial summary
Regorafenib is an anti-cancer drug that blocks several proteins which are involved in the growth of cancer. It has been approved for different types of cancers of the digestive system and is being tested for use in some other solid tumors. Cancers that start in an organ, a muscle, or a bone form a solid tumor. Read more about this study

About this study
Official title: A Single Arm, Open-label, Multicenter Phase 2 Study of Regorafenib in Participants Who Have Been Treated in a Previous Bayer-sponsored Regorafenib Study (Monotherapy or Combination Treatment) That Has Reached the Primary Completion Endpoint or the Main Data Analysis or Has Been Stopped Prematurely.
Regorafenib is an anti-cancer drug that blocks several proteins which are involved in the growth of cancer. It has been approved for different types of cancers of the digestive system and is being tested for use in some other solid tumors. Cancers that start in an organ, a muscle, or a bone form a solid tumor.
This study is for participants with solid tumors who have been taking regorafenib in other Bayer studies. They can continue taking regorafenib if it is working when treatment with regorafenib in their previous study ends.

The main purpose of this study is to find:
- How safe is the continued treatment with regorafenib in participants with solid tumors?
- How well is the continued treatment with regorafenib tolerated by participants with solid tumors?
Participants will continue with the same dose of regorafenib that they were taking in their previous study as long as the treatment works for them/they want to continue the treatment/other medical conditions do not prevent them from participating in the study. For participants that are under 18 years of age, regorafenib tablets will be taken by mouth once daily for 2 weeks and repeat again after a 1-week gap. For participants that are over 18 years of age, regorafenib tablets will be taken by mouth once daily for 3 weeks and repeat again after a 1-week gap.
At the start of the study, researchers will review participants' records from the previous study. During the study, researchers will use blood samples and X-rays taken from participants under the age of 18 years to check how safe regorafenib is for children. They will also monitor any medical problems that participants may have during the study. After the last dose, follow-up will be done either within 14 days when participants visit their study doctor or within 30-35 days by phone call.
Both the researchers and the participants will know the dose of regorafenib the participants receive during the study.

Regorafenib (Stivarga, BAY73-4506)Drug
Participants will be treated with the regorafenib dose taken during the last cycle of the feeder study. Adult participants will receive either 60, 80, 90, 120, or 160 mg orally (p.o.) once daily (qd) for 3 weeks of every 4-week cycle (i.e. 3 weeks on, 1 week off). Pediatric participants will receive 82 mg/m^2 p.o. qd for 14 days, in a 14 days on/7 days off schedule (21-day cycle).

A Phase 2 study testing Regorafenib (Stivarga, BAY73-4506) in people with Solid Malignant Tumors, run by Bayer at 7 sites in 5 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in France, Japan, South Korea, Spain, Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of participants with serious adverse events (SAEs) and protocol-specified AEs and their severity (time frame: through study completion, an average of 2.5 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2026.
