CLINGLIO: 2-OHOA With RT and TMZ for Adults With Glioblastoma
Study Details
Study Description
Brief Summary
The proposed Phase IIB/III randomized, double-blind, placebo-controlled trial in subjects with newly diagnosed primary glioblastoma multiforme (ndGBM) aims to compare the efficacy and safety of 2-OHOA versus placebo, given with standard of care (SoC) therapy of radiation therapy plus temozolomide (TMZ), followed by an adjuvant treatment of 6 month period of TMZ and then 2-OHOA or placebo in monotherapy.

Phase 2/Phase 3 |
Detailed Description
This is a randomized, double-blind, placebo-controlled, 2 parallel arms (1:1 ratio), adjuvant trial to assess the efficacy of 2-hydroxyoleic acid (2-OHOA) versus placebo in patients with newly diagnosed, IDH1 wildtype, GBM. In all arms, patients will receive the SoC and will be randomized to receive either placebo or 2-OHOA dose.
The study is planned to enrol 140 patients. The primary endpoints of the study are PFS (for CMA) and OS (for FMA) as assessed after observing at least 66 PFS events and at least 90 OS events, respectively. It is expected that the analysis for PFS will be performed 1-2 years earlier than the analysis for OS.
After 45 events for PFS are observed, a formal interim analysis will be performed and the data reviewed by an Independent Data Monitoring Committee (IDMC) or may be activated by the IDMC 12 months after the inclusion of the last patient if follow up is sufficient to identify an overall PFS or OS significant deviation from the literature. After reviewing the interim results, the iDMC will make recommendations regarding: the sample size and the continuation of the trial overall.
Further, the sample size and events will be re-estimated to ensure that the statistical power is maintained given the estimated treatment effect at interim analysis. The events/sample size increase will be based on the considerations of the success probability.
For that purpose, based on the conditional power, the interim results will be classified into the following zones: favourable, unfavourable or promising.
If the interim results fall in the promising zone, then it is planned to increase the total number of events both for PFS and OS by up to 50%, with up to 99 events for PFS and up to 135 events for OS. The total sample size will also be increased to up to 210 patients to ensure the desired number of events within a realistic time. If the interim results are favourable or unfavourable, the study size will remain as initially planned with 66 events for PFS and 90 for OS, collected from 140 patients.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Placebo Comparator: Arm A: SoC + placebo for 2-OHOA Chemoradiation Phase: all subjects undergo focal RT, with a treatment given 5 days per week over ~6 weeks (no more than 7 weeks). TMZ will be administered at 75 mg/m2 orally, once daily, continuously throughout the RT for a maximum of 49 days. Subjects in Arm A will receive placebo every day from Day 1 of week 3 to the end of this Phase. The start of the first cycle during the Maintenance (Adjuvant) Phase will be scheduled ~28 days (and never more than 42 days) after the last day of chemoradiation. During the Maintenance Phase, subjects will receive oral TMZ 150-200 mg/m2 once daily on Days 1-5 of each 28-day cycle for 6 cycles. Subjects in Arm A will receive placebo every day during the first 3 weeks of each 28-day cycle and until progression. Patients will continue with Placebo after cycle 6 of the monotherapy phase until end of study. Adjuvant treatment will be discontinued upon determination of tumour progression, unacceptable toxicity or refusal to continue study treatment. |

The QLQ-C30 is a 30-item patient self-report questionnaire composed of both multi-item and single scales, including five functional scales (physical, role, emotional, social, and cognitive), three symptom scales (fatigue, nausea and vomiting, and pain), a global health status/HRQoL scale, and six single items (dyspnoea, insomnia, appetite loss, constipation, diarrhoea, and financial difficulties). Subjects rate items on a four-point scale, with 1 as "not at all" and 4 as "very much". The QLQ-C30 was developed and validated for use in a cancer patient population, and its reliability and validity is highly consistent across different language-cultural groups.
- To evaluate Health-related Quality of Life (HRQoL) [Baseline and Post-baseline: day 1 of each odd cycle of maintenance/monotherapy phase and at progression]
HRQoL assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, EORTC-QLQ C30, version 3.0 and brain cancer specific QLQ-BN20. The QLQ-BN20 is a 20-item patient self-report questionnaire that was developed specifically as a module for subjects with brain cancer. It consists of four domain scores, including future uncertainty, visual disorder, motor dysfunction, and communication deficit, as well as seven individual symptom items (headache, seizures, drowsiness, hair loss, itching, difficulty with bladder control, and weakness of both legs). Subjects rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." A retrospective validation study has been conducted confirming its psychometric validity.
