BAL0891 in Patients With Advanced Solid Tumors

Advanced Solid Tumor Clinical Trial

Official title: A Phase 1 Study of BAL0891 as Monotherapy and in Combination With Chemotherapy in Patients With Advanced Solid Tumors

Status Recruiting

Clinical Trial Summary

This study is a multiple cohort, multicenter, open-label Phase 1 study with dose-escalation substudies investigating intravenous (IV) BAL0891 as monotherapy, and in combination with carboplatin or paclitaxel, to determine the safety and tolerability of increasing doses of BAL0891 in patients with advanced solid tumors.

Clinical Trial Description

Substudy 1 (monotherapy dose-escalation cohorts) This study will be initiated with enrollment into Substudy 1 and will estimate the safety, tolerability, PK, and PD of increasing doses of BAL0891 in patients with advanced solid tumors. The starting dose will be 5 mg based on the GLP (Good Laboratory Practice) toxicology studies. Dose escalation will comprise a dose range from a dose of 5 mg up to a maximum absolute dose of 480 mg, with eight nominal dose levels (DLs) of 5 / 10 / 20 / 40 / 80 / 160 / 320 / 480 mg. Intra-patient dose escalations are only allowed for patients enrolled in single-patient DL Cohorts 1.1, 1.2, and 1.3. From DL Cohort 1.4 onwards, the projected maximum dose-escalation factor will be two-fold; if the DL cohort investigates an increased dose, dosing of the patients within the cohort must be separated by at least 7 days. For cohorts in which doses are not increased (including backfill enrollment), patients may be enrolled concurrently. BAL0891 will be administered intravenously (IV) on Day (D) 1 and D8 every 3 weeks (Q3W); for the schedule of assessments of Regimen A. Alternative 21-day or 28-day dosing regimens may be investigated; for the schedule of assessments of Regimens B-D. Substudies 2 and 3 (dose-escalation cohorts for combination regimens) Enrollment into Substudies 2 and 3 may commence as early as first signs of expected target toxicity and/or efficacy with Regimen A (or an alternative monotherapy regimen) have been observed, or alternatively, once the MTD of BAL0891 monotherapy has been assessed. Patients enrolled into Substudies 2 and 3 will be treated with increasing doses of BAL0891 in combination with carboplatin and paclitaxel, respectively, and dose escalation of both BAL0891 and carboplatin/paclitaxel if required will use the same cumulative BLRM-EWOC model as Substudy 1. The starting dose of BAL0891 in combination with carboplatin or paclitaxel will be a safe DL determined in Substudy 1 but not higher than approximately half the MTD. Backfill enrollment of up to a total of 30 additional patients for both substudies (who may be enrolled concurrently) may be used to better estimate the RP2D for each combination if required. ;
