What is being measured
The primary outcome is the main question the study is designed to answer.
Overall Response Rate (ORR) by the Investigator
ORR was defined as the percentage of participants with the best overall confirmed response of complete response (CR) or partial response (PR) according to the appropriate response assessment criteria including Response Evaluation Criteria in Solid Tumors (RECIST 1.1) or Response Assessment in Neuro-Oncology (RANO) for the disease setting as assessed by the Investigator. CR or PR was confirmed at a subsequent scan (>=4 weeks) if the criteria for each are met . The exact 95% confidence intervals (CIs) were calculated using Clopper-Pearson method.
Measured: Up to 23 months
Secondary outcomes (7)
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
An adverse event (AE) is any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An serious adverse event (SAE) is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment. An AE is considered to be treatment-emergent if it has a start date/time on or after the first administration of study drug until 30 days after the last dose of study drug and before the start of subsequent therapy, whichever comes earlier. The distribution of AEs was analyzed by the type, frequency and severity for TEAEs.
Measured: Up to 23 months
Number of Participants With Worst Case Hematology Results by Maximum Grade Increase Post-baseline Relative to Baseline
Blood samples were collected for the analysis of following hematology parameters: anemia, neutrophil count decreased and white blood cell decreased. Grade 1 (G1): mild; Grade 2 (G2): moderate; Grade 3 (G3): severe; Grade 4 (G4) life-threatening or disabling. Higher grade indicates greater severity and an increase in CTCAE grade was defined relative to the Baseline grade. Any worst-case post baseline increase to G2, G3, and G4 are presented. The laboratory parameters were graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.
Measured: Baseline and up to 23 months
Number of Participants With Worst Case Chemistry Results by Maximum Grade Increase Post-baseline Relative to Baseline
Blood samples were collected for the analysis of following chemistry parameters: creatine phosphokinase (CPK) increased, hypokalemia, hypoalbuminemia, hypercalcemia, hypocalcemia and hyponatremia. Grade 1 (G1): mild; Grade 2 (G2): moderate; Grade 3 (G3): severe; Grade 4 (G4) life-threatening or disabling. Higher grade indicates greater severity and an increase in CTCAE grade was defined relative to the Baseline grade. Any worst-case post baseline increase to G2, G3, and G4 are presented. The laboratory parameters were graded according to CTCAE version 5.
Measured: Baseline and up to 23 months
Duration of Response (DOR) in Participants With Best Overall Response
Duration of response was defined as the interval from the date of the first documentation of tumor response (CR or PR) that was subsequently confirmed by investigator assessment to the date of first occurrence of radiographic disease progression based on RECIST 1.1 or RANO criteria or death due to any cause, whichever occurs earlier. DOR was estimated using Kaplan-Meier method.
Measured: Up to 23 months
Duration of Progression Free Survival
Progression free survival was defined as the interval from the date of the first dose to the first occurrence of radiographic disease progression based on RECIST 1.1 or RANO criteria or death due to any cause, whichever occurs earlier. Progression free survival was estimated using Kaplan-Meier method.
Measured: Up to 23 months
Duration of Overall Survival
Overall survival is defined as the interval from the date of the first dose until the recorded date of death due to any cause. Overall survival was estimated using Kaplan-Meier method.
Measured: Up to 23 months
Time to Response
Time to Response was defined in participants with best overall response of complete response or partial response as determined by Investigator. It is the interval from the date of the first dose to date of first documentation of tumor response that was subsequently confirmed by investigator assessment.
Measured: Up to 23 months

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Tovorafenib in people with Melanoma and Solid Tumor, run by Day One Biopharmaceuticals, Inc. at 20 sites in 7 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 5 inclusion and 3 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: stopped early, as of the sponsor's last update on 2 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 20 sites in United States, South Korea, Spain, Canada, Australia and 2 more countries. 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?
Yes. Results are posted in the registry (first posted 2 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Overall Response Rate (ORR) by the Investigator (time frame: Up to 23 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04985604, which also lists 1 linked publication.
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 2 Oct 2025.
