A Phase I/II Trial of TRC102 (Methoxyamine HCl) in Combination With Temozolomide in Patients With Relapsed Solid Tumors and Lymphomas

The Number of Dose Limiting Toxicities Observed in Participants Receiving Oral TRC102 in Combination With Oral TMZ

时间窗: At dose-limiting toxicity (DLT) determined in the first cycle; approximately 28 days

Dose-limiting toxicities (DLTs) are defined as toxicities occurring within the first cycle of treatment felt to be possibly, probably, or definitely related to administration of study drugs and fulfilling one of the following criteria: Grade 4 neutropenia, febrile neutropenia, neutropenic infection: Grade ≥ 3 neutropenia with grade ≥ 3 infection, Grade ≥ 3 thrombocytopenia, a drop in hemoglobin (Hgb) ≥3.0 g/dL over one week, and all Grade ≥ 3 non-hematologic toxicity other than: non-bloody diarrhea Grade 3 that is corrected to Grade ≤ 2 within 24 hours, nausea and vomiting Grade 3 that is corrected to Grade ≤ 1 within 24 hours, creatinine Grade 3 corrected to Grade ≤ 1 within 48 hours, and Grade 3 electrolyte abnormalities. Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe. Grade 4 is life-threatening. And Grade 5 is death related to adverse event.

Phase 1 Pharmacokinetic (PK) Profile: the Percentage of TRC102 Dose Recovered From Participant Urine in Participants Treated With Oral TRC102 in Combination With Temozolomide (TMZ)

时间窗: First day of treatment

Urine samples will be collected, and pharmacokinetics will be assessed in phase I portion of the study. Samples will be analyzed using a validated liquid chromatography-mass spectrometry (LC-MS) or liquid chromatography with tandem mass spectrometry (LC-MS-MS) method.

Phase 1 Maximum Tolerated Dose (MTD) of Oral Temozolomide (TMZ) in Participants With Refractory Solid Tumors.

时间窗: First cycle of treatment; approximately 28 days

The MTD or recommended Phase II dose is the dose level at which no more than 1 of 6 participants experience dose-limiting toxicity (DLT) during the first cycle of treatment, and the dose below that at which at least 2 (of ≤ 6) participants have DLT as a result of the drug. DLTs will be defined as toxicities occurring within the first cycle of treatment and is felt to be possibly, probably, or definitely related to administration of study drugs and fulfills one of the following criteria: hematologic toxicities - Grade 4 neutropenia, febrile neutropenia, neutropenic infection: Grade ≥ 3 neutropenia with grade ≥ 3 infection, Grade ≥ 3 thrombocytopenia, a drop in hemoglobin (Hgb) ≥3.0 g/dL over one week, any degree of lymphopenia, or leukopenia in the absence of grade 4 neutropenia will not be considered dose limiting, and Grade ≥ 3 non-hematologic toxicity. Grade ≥ 3 electrolyte abnormalities will not be considered dose limiting.

Phase 2: Response Rate of This Combination in Participants With Colon Cancer, Non-small Cell Lung Cancer (NSCLC), and Granulosa Cell Ovarian Cancer

时间窗: Response rate at one year

Response and progression will be evaluated in this study using the new international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1). Response was measured by the Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1). Complete response (CR) is disappearance of all target lesions. Partial response (PR) is at least a 30% decrease in the sum of the diameters of target lesions. Stable Disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. Progressive disease (PD) is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on-study (this includes the baseline sum if that is the smallest on study). The appearance of one or more new lesions is also considered progressions.

Phase 1 Pharmacokinetic (PK) Profile of Oral TRC102 When Administered in Combination With Temozolomide (TMZ) as Measured by Maximum Plasma Concentration (Cmax) of TRC102: Mean (Standard Deviation)

时间窗: First 5 days of treatment

Blood samples will be collected, and pharmacokinetics will be assessed in the phase I portion of the study. Samples will be analyzed using a validated LC-MS or LC-MS/MS method in human plasma. The maximum observed analyte concentration in plasma was reported.

Phase 1 Maximum Tolerated Dose (MTD) of Oral TRC102 in Participants With Refractory Solid Tumors.

时间窗: First cycle of treatment; approximately 28 days

The MTD or recommended Phase II dose is the dose level at which no more than 1 of 6 participants experience dose-limiting toxicity (DLT) during the first cycle of treatment, and the dose below that at which at least 2 (of ≤ 6) participants have DLT as a result of the drug. DLTs are defined as toxicities occurring within the first cycle of treatment felt to be possibly, probably, or definitely related to administration of study drugs and fulfilling one of the following criteria: Grade 4 neutropenia, febrile neutropenia, neutropenic infection: Grade ≥ 3 neutropenia with grade ≥ 3 infection, Grade ≥ 3 thrombocytopenia, a drop in hemoglobin (Hgb) ≥3.0 g/dL over one week, and all Grade ≥ 3 non-hematologic toxicities other than: non-bloody diarrhea Grade 3 that is corrected to Grade ≤ 2 within 24 hours, nausea and vomiting Grade 3 that is corrected to Grade ≤ 1 within 24 hours, creatinine Grade 3 corrected to Grade ≤ 1 within 48 hours, and Grade 3 electrolyte abnormalities.
