Study Endpoints

Primary Endpoints

Phase 1 Dose Escalation: Number of Participants With Dose Limiting Toxicities (DLTs)
From initial dose until 28 days after infusion of the first cohort dose on Cycle 1 Day 1

DLTs are defined as specific Grade 3 and 4 hematologic and hepatic nonhematologic events or any other Grade ≥3 adverse events related to treatment that occur during the DLT evaluation period after administration of TAK-505, except events that are clearly due to the underlying disease or an extraneous cause.

Phase 1 Dose Escalation: Number of Participants With Treatment Emergent Adverse Events (TEAEs), Clinically Significant Laboratory Values and Vital Signs
From first dose of trial intervention through 30 days after administration of the last dose of trial intervention (up to approximately 52 months)

An Adverse Event (AE) is any untoward medical occurrence in a clinical trial participant, temporally associated with the use of TAK-505, whether or not the occurrence is considered related to the trial intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of TAK 505. TEAEs that occur after administration of the first dose of trial intervention and through 30 days after the last dose of trial intervention will be tabulated.

Phase 2 Dose Expansion: Confirmed Overall Response Rate (ORR)
Up to end of study (up to approximately 52 months)

ORR is defined as the percentage of participants who achieve partial response (PR) or complete response (CR), as assessed by the investigator, per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1)

Phase 2 Dose Expansion: Number of Participants With TEAEs, Clinically Significant Laboratory Values and Vital Signs
From first dose of trial intervention through 30 days after administration of the last dose of trial intervention (up to approximately 52 months)

An AE is any untoward medical occurrence in a clinical trial participant, temporally associated with the use of TAK-505, whether or not the occurrence is considered related to the trial intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of TAK 505. TEAEs that occur after administration of the first dose of trial intervention and through 30 days after the last dose of trial intervention will be tabulated.

Secondary Endpoints

Phase 1 and Phase 2: Maximum Observed Concentration (Cmax) of TAK-505
Phase 1, all cycles: pre-dose and end of infusion (EOI) except Cycles 1 and 3: Day1-pre-dose and post dose up to 168 hours; Day 15-pre-dose and EOI; End of treatment (EOT) (up to 7 months); Phase 2, all Cycles: pre-dose, EOI and EOT (up to 9 months)
Phase 1 and Phase 2: Time to Maximum Concentration (tmax) of TAK-505
Phase 1, all cycles: pre-dose and EOI except Cycles 1 and 3: Day1-pre-dose and post dose up to 168 hours; Day 15-pre-dose and EOI; EOT (up to 7 months); Phase 2, all Cycles: pre-dose, EOI and EOT (up to 9 months)
Phase 1 and Phase 2: Area Under the Concentration-Time Curve From Time 0 to Time of the Last Quantifiable Concentration (AUC0-last) of TAK-505
Phase 1, all cycles: pre-dose and EOI except Cycles 1 and 3: Day1-pre-dose and post dose up to 168 hours; Day 15-pre-dose and EOI; EOT (up to 7 months); Phase 2, all Cycles: pre-dose, EOI and EOT (up to 9 months)

Frequently asked questions about TAK-505

What is TAK-505 used for?

TAK-505 is an investigational small molecule being studied for the treatment of malignant solid tumors in adults. It is in Phase 1 clinical development and is not yet approved for any indication. The ongoing study enrolls adults 18 years and older with solid tumors.

Who is developing TAK-505?

TAK-505 is being developed by Takeda Pharmaceutical Company Limited, which trades on the New York Stock Exchange under the ticker TAK. Takeda is the sponsor of the clinical program evaluating the compound in oncology.

What phase is TAK-505 in?

TAK-505 is in Phase 1 clinical development. It is an investigational agent and has not been approved by the FDA or any other regulatory agency. The Phase 1 program is currently recruiting participants with malignant solid tumors.

What clinical trials is TAK-505 in?

TAK-505 is being evaluated in one clinical trial, NCT07436728, titled A Study of TAK-505 in Adults With Solid Tumors. The trial is a controlled Phase 1 study that is currently recruiting, with a planned enrollment of 151 participants across sites in the United States.

Is TAK-505 biomarker selected?

Yes. The TAK-505 Phase 1 trial NCT07436728 uses biomarker-based selection, meaning participants are enrolled based on specific biomarker criteria rather than an unselected solid tumor population. The study enrolls adults 18 years and older of any sex and does not include healthy volunteers.
