Arm | Intervention/treatment |
---|---|
Experimental: TAS2940 Dose Escalation
Dose escalation will assess the safety and determine the maximum tolerated dose, the recommended phase 2 dose and the recommended dosing regimen of TAS2940 administered orally.
|
Drug: TAS2940
Study participants with solid tumors and EGFR or HER2 aberrations will receive TAS2940 tablets daily at increasing doses until MTD is reached. |
Experimental: Dose Expansion Non-small Cell Lung Cancer
Dose expansion will assess preliminary anti-tumor activity in select solid tumors characterized by HER2 or EGFR aberrations
|
Drug: TAS2940
Study subjects with select solid tumors characterized by EGFR or HER2 aberrations will receive TAS2940 at the dose identified during Dose Escalation phase. |
Experimental: Dose Expansion Breast Cancer
Dose expansion will assess preliminary anti-tumor activity in select solid tumors characterized by HER2 or EGFR aberrations
|
Drug: TAS2940
Study subjects with select solid tumors characterized by EGFR or HER2 aberrations will receive TAS2940 at the dose identified during Dose Escalation phase. |
Experimental: Dose Expansion Gliblastoma
Dose expansion will assess preliminary anti-tumor activity in select solid tumors characterized by HER2 or EGFR aberrations.
|
Drug: TAS2940
Study subjects with select solid tumors characterized by EGFR or HER2 aberrations will receive TAS2940 at the dose identified during Dose Escalation phase. |
Experimental: Dose Expansion Solid tumors
Dose expansion will assess preliminary anti-tumor activity in select solid tumors characterized by HER2 or EGFR aberrations.
|
Drug: TAS2940
Study subjects with select solid tumors characterized by EGFR or HER2 aberrations will receive TAS2940 at the dose identified during Dose Escalation phase. |
- Dose Escalation:Maximum Tolerated Dose (MTD) [ Time Frame: One Month ]Determine the incidence of dose-liming toxicities (DLTs) and adverse events (AEs) graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v5.0 within the first cycle
- Dose Expansion:Overall Response Rate [ Time Frame: 6 Months ]Document the ORR, defined as proportion of patients experiencing a best overall response of Complete Response (CR) or Partial response (PR) based on investigator accessed radiographic response per RECIST 1.1 or RANO criteria
- Dose Escalation: Overall Response Rate (ORR) [ Time Frame: 6 Months ]Document the ORR defined as proportion of patients experiencing a best overall response of Complete Response (CR) or Partial response (PR) based on investigator accessed radiographic response per RECIST 1.1 or RANO criteria
- Dose Escalation:Pharmacokinetic (PK) Profile [ Time Frame: 3 Months ]Evaluation of the maximum observed plasma concentration; time to reach maximum concentration, area under the Concentration-time curve and time it takes for plasma concentration to fall by half its original value (T1/2) of TAS2940
- Dose Expansion:Incidence of treatment-emergent Adverse Events (Safety and tolerability) [ Time Frame: Estimated up to 6 months ]Safety and tolerability of TAS2940 based on reported AEs, graded according to NCI-CTCAE v.5.0
- Dose Expansion:Duration of Response (DOR) [ Time Frame: Estimated up to 6 months ]DOR, defined as time from the first documentation of response to date of objective tumor progression or death due to any cause, whichever occurs first.
- Dose Expansion:Disease Control Rate (DCR) [ Time Frame: Estimated up to 6 months ]DCR, defined as the proportion of patients experiencing a best overall response of Stable Disease (SD), PR or CR
- Dose Expansion:Progression Free Survival (PFS) [ Time Frame: Estimated up to 6 months ]Date of PR or CR to date of objective progression or death due to any cause.
- Dose Expansion:Pharmacokinetic profile of TAS2940 [ Time Frame: 3 Months ]Evaluation of the maximum observed plasma concentration; time to reach maximum concentration, area under the Concentration-time curve and time it takes for plasma concentration to fall by half its original value (T1/2) of TAS2940
