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 developed for the treatment of malignant solid tumors. It is currently in Phase 1 clinical development, meaning it has not yet been approved by regulatory authorities and is still being studied for safety and efficacy in humans.

Who makes TAK-505?

TAK-505 is being developed by Takeda Pharmaceutical Company Limited, a global biopharmaceutical company. Takeda is listed on the stock exchange under the ticker symbol TAK. The company is conducting clinical trials to evaluate the safety and effectiveness of this investigational drug.

What phase is TAK-505 in?

TAK-505 is currently in Phase 1 clinical development. This is the earliest stage of human testing, focused on evaluating the drug's safety, tolerability, and pharmacokinetics in patients with malignant solid tumors. The drug is investigational and has not yet received regulatory approval.

What clinical trials is TAK-505 in?

TAK-505 is being studied in a Phase 1 clinical trial with the identifier NCT07436728, titled 'A Study of TAK-505 in Adults With Solid Tumors.' This trial is currently recruiting participants in the United States and aims to enroll approximately 151 adults aged 18 years and older with malignant solid tumors.

Is TAK-505 FDA approved?

TAK-505 is not FDA approved. It is an investigational drug currently in Phase 1 clinical trials. The ongoing study, NCT07436728, is evaluating the drug's safety and tolerability in adults with malignant solid tumors. Regulatory approval would require successful completion of further clinical trials and review by health authorities.
