- Lead Sponsor
- Basilea Pharmaceutica
- Brief Summary
First in human, open-label, dose escalation (Phase I) and expansion study (Phase 2a) of oral lisavanbulin (BAL101553) in adult patients with advanced solid tumors and adult patients with recurrent or progressive glioblastoma (GBM) or high-grade glioma (HGG).
- Detailed Description
This was the first study of the oral formulation (hard capsules) of lisavanbulin. Lisavanbulin was administered once daily during each day of a 28-day treatment cycle to adults with advanced or recurrent solid tumors or recurrent or progressive GBM / HGG who had failed standard therapy, or for whom no effective standard therapy was available.
In Phase 1, the highest dose of lisavanbulin was determined that could safely be given to adults with advanced or recurrent solid tumors, recurrent or progressive GBM / HGG.
In Phase 2a, the tolerability and potential anticancer activity of oral lisavanbulin was assessed in patients with recurrent GBM whose tumor tissue tests positive for end-binding protein 1 (EB1). The study also measured pharmacokinetics.

-
Patients with advanced solid tumors had to have an Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1 and patients with recurrent or progressive glioblastoma had to have an ECOG performance status ≤ 2
Main
-
Patients with advanced or recurrent solid tumors who had received chemotherapy, radiotherapy, immunotherapy, or investigational agents within 4 weeks (2 weeks for single fraction of palliative radiotherapy, 6 weeks for nitrosoureas or mitomycin C) prior to starting study drug or who had not recovered from side effects of prior therapies
Patients with recurrent or progressive GBM / HGG who had: received radiotherapy within 6 weeks (Phase 1) or 12 weeks (Phase 2a), unless there was a new area of enhancement consistent with recurrent tumor outside the radiation field; received administration of prior anti-tumor chemotherapy within 4 weeks, or within 6 weeks for nitrosoureas; undergone surgical resection within 4 weeks (Phase 2a: 2 weeks) or a stereotactic biopsy/core biopsy within 1 week prior to starting study drug;
-
Patients who have had prior exposure to lisavanbulin
-
Inability to swallow oral medication
-
Increase in steroid dose in GBM or HGG patients within 5 days prior to first study-drug administration or requirement for > 6 mg/day dexamethasone or equivalent for symptom control.
-
Patients with gastrointestinal disease or those who have had a procedure that was expected to interfere with the oral absorption or tolerance of lisavanbulin
-
Symptomatic brain metastases or leptomeningeal disease, which was indicative of active disease, in patients with advanced or recurrent solid tumors.
-
Peripheral neuropathy ≥ CTCAE grade 2.
-
Uncontrolled intercurrent illness that would have unduly increased the risk of toxicity or limit compliance with study requirements
-
Systolic blood pressure (SBP) ≥ 160 mmHg or diastolic blood pressure (DBP) ≥ 100 mmHg at the screening visit.
-
Blood pressure (BP) combination treatment with more than two antihypertensive medications.
-
Women who were pregnant or breast-feeding. Men or women of reproductive potential who were not willing to apply effective birth control

Group Intervention Description Phase 1 dose escalation portion Lisavanbulin Phase 1 dose escalation portion Phase 1 dose escalation portion - an accelerated 3+3 titration design in patients with: 1. advanced or recurrent solid tumors 2. recurrent or progressive GBM / HGG Phase 2a dose expansion portion Lisavanbulin Phase 2a expansion portion Phase 2a expansion portion (Simon's two-stage design) - Patients with recurrent and EB1-positive GBM
- Primary Outcome Measures
Name Time Method Phase 2a: Best Objective Response Until the study discontinuation, on average 161 days (maximum of 381 days) The best objective response was calculated as the proportion of patients responding (i.e., with a best observed objective response of complete or partial response) based on "radiological assessment in neuro-oncology (RANO)" criteria
Phase 1: Maximum Tolerated Dose (MTD) of Daily Oral Lisavanbulin During first 28 day cycle First 28-day treatment cycle dose limiting toxicities (DLT) graded according to Common Terminology Criteria for Adverse Events (CTCAE) in the MTD-determining population in Phase 1 based on the number of participants with adverse effects as measure of tolerability at various dose levels
Phase 2a: Objective Response Rate (ORR) Until the study discontinuation, on average 161 days (maximum of 381 days) The ORR was calculated as the percentage of patients (rate) with complete and partial responses and its 95% Confidence Interval (CI) based on RANO criteria
- Secondary Outcome Measures
Name Time Method Cmax of Avanbulin (BAL27862) Plasma PK profiles were obtained on Cycle 1, Day 1 and on Cycle 2, Day 1 (pre-dose and from 0 up to 24 h post-dose) for all patients in the Phase 1 study who received lisavanbulin. For Phase 2 a study, PK parameters were obtained only on Cycle 1, Day 1 Pharmacokinetic parameter "Peak Plasma Concentration" Cmax of avanbulin Lisavanbulin (BAL101553) is the prodrug of avanbulin (BAL27862)
Phase 1: Best Objective Response Until the end of treatment, on average 151 days (maximum of 1653 days), every other 28 day cycle The best objective response was calculated as the proportion of patients responding (i.e., with a best observed objective response of complete response (CR) or partial response (PR), according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria v1.1 for patients with advanced or recurrent solid tumors); and based on RANO criteria for patients with recurrent or progressive GBM / HGG
Phase 2a: PFS at 6 Months 6 months Percentage of patients without disease progression based on RANO criteria 6 months after the start of treatment. The values were determined using the Kaplan-Meier and Brookmeyer-Crowley methods.
Number of Patients With CTCAE Grade 3-4 TEAEs TEAEs were defined as all events occurring after lisavanbulin treatment began and up to 28 days after last study drug administration which corresponded to a maximum of 1653 days (4,5 years) Number of patients experiencing treatment-emergent adverse events (TEAE) of CTCAE Grade 3 or 4
Tmax of Avanbulin (BAL27862) Plasma PK profiles were obtained on Cycle 1, Day 1 and on Cycle 2, Day 1 (pre-dose and from 0 up to 24 h post-dose) for all patients in the Phase 1 study who received lisavanbulin. For Phase 2 a study, PK parameters were obtained only on Cycle 1, Day 1 Pharmacokinetic parameter "Time to Peak Plasma Concentration" Tmax of avanbulin (BAL27862) Lisavanbulin (BAL101553) is the prodrug of avanbulin (BAL27862).
AUC of Avanbulin (BAL27862) Plasma PK profiles were obtained on Cycle 1, Day 1 and on Cycle 2, Day 1 (pre-dose and from 0 up to 24 h post-dose) for all patients in the Phase 1 study who received lisavanbulin. For Phase 2 a study, PK parameters were obtained only on Cycle 1, Day 1 Pharmacokinetic parameter "Area under the plasma concentration versus time curve" AUC of avanbulin (BAL27862) Lisavanbulin (BAL101553) is the prodrug of avanbulin (BAL27862).
Phase 2a: PFS 1 year PFS was defined as the interval between the date of drug administration and the earliest date of objective disease progression based on RANO criteria for patients with recurrent or progressive GBM / HGG. Patients who have not progressed or died at the end of the study were censored at the time of their latest objective tumor assessment.
Phase 1: Objective Response Rate (ORR) Until the study discontinuation, on average 151 days (maximum 1653 days), every other 28 day cycle The ORR was calculated as the percentage of patients (rate) with complete and partial responses and its 95% CI based on RECIST criteria v1.1 for patients with advanced or recurrent solid tumors; and based on RANO criteria for patients with recurrent or progressive GBM / HGG
Phase 2a: Overall Survival (OS) at 12 Months 1 year Percentage of patients alive 12 months after the start of treatment. The values were determined using the Kaplan-Meier and Brookmeyer-Crowley methods.
