Summary
This pilot feasibility study aims to set the foundation to investigate the applicability of QPOP drug selection followed by CURATE.AI-guided dose optimisation of the selected azacitidine combination therapy for solid tumours using CURATE.AI within the current clinical setting. QPOP will identify drug interactions towards optimal efficacy and cytotoxicity from the pre-specified drug pool based on ex vivo experimental data from the individual participant's tissue sample model. With these drug interactions, QPOP will identify the optimal drugs for the specific participant whose biopsy provided the cells for the ex vivo experimentation. Subsequently, CURATE.AI will be used to guide dosing for the selected combination therapy for that participant. Individualised CURATE.AI profiles will be generated based on each participant's response to a set of drug doses. Subsequently, the personalised CURATE.AI profile will be used to recommend the efficacy-driven dose. CURATE.AI will operate only within the safety range for each drug pre-specified for each participant. This pilot feasibility study will inform the investigators on the logistical and scientific feasibility of performing a large-scale randomised controlled trial (RCT) with the selected azacitidine combination therapy regimens and response markers. A secondary objective is to collect toxicity and efficacy data using established and exploratory response markers within and in-between cycles as exploratory outcomes.
Eligibility
Inclusion Criteria9
- Males and females ≥ 21 years of age.
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 2.
- Patients must meet the following clinical laboratory criteria within 21 days of starting treatment:
- Absolute neutrophil count (ANC) ≥ 1,000/mm3 and platelet ≥ 50,000/mm3
- Total bilirubin ≤ 1.5 x the upper limit of the normal range (ULN). Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 x ULN of ≤ 5 ULN if involvement of the liver.
- Calculated creatinine clearance ≥ 30 mL/min or creatinine \< 1.5 x ULN.
- Diagnosed with breast or gastric cancer, where docetaxel, paclitaxel or irinotecan is indicated for palliative therapy.
- Patients who have undergone QPOP drug screen (e.g. under QGAIN (2019/00924) or NGAIN trial (2021/00009) where the drug screen indicated potential benefit of combining azacitidine with taxane or irinotecan.
- Patients must have raised response marker above upper limit of local laboratory normal (e.g. CEA and/or CA19-9, CA 15-3, CA 125, AFP, and methylation markers such as but not limited to DNMT).
Exclusion Criteria8
- Patients who are lactating or pregnant.
- Patients with clinically significant hypersensitivity to one or more of the selected regimen's constituent drug(s) (e.g. patients with clinically significant hypersensitivity to irinotecan may not be enrolled on azacitidine + irinotecan, but may be allowed on azacitidine + paclitaxel or azacitidine + docetaxel).
- Contraindication to any of the required concomitant drugs or supportive treatments.
- Any clinically significant medical disease or psychiatric condition that, in the co-investigator's opinion, may interfere with protocol adherence or a subject's ability to give informed consent.
- Major surgery within 28 days prior to start of the treatment.
- Active congestive heart failure (New York Heart Association \[NYHA\] Class III or IV), symptomatic ischaemia, or conduction abnormalities uncontrolled by conventional intervention. Myocardial infarction within 4 months prior to informed consent obtained.
- Patients who previously underwent chemotherapy treatment with either docetaxel, paclitaxel and/or irinotecan may still be able to enrol into treatment with the same drug in combination with azacitidine provided they fulfil all other criteria and approval is sought by PI and Sponsor (e.g. patients previously treated with paclitaxel and are enroling for treatment with paclitaxel + azacitidine).
- Patients with clinical suspicion or diagnosis of Gilbert's syndrome will not be allowed to enrol with azacitidine + irinotecan, but may be allowed to enrol for treatment with azacitidine + docetaxel or azacitidine + paclitaxel provided they fulfil all other criteria.
Interventions
QPOP is a mechanism-agnostic platform for optimizing drug selection. QPOP uses a quadratic equation to describe the patient-specific drug-drug interaction space based solely on experimentally derived drug-response data on individual patient's tissue sample, from which optimal drug combinations can be identified. Drug selection via QPOP allows for identification of an optimal combination therapy without the need for exhaustive testing of every combination. The first stage of the trial aims to generate a personalised QPOP drugs list for each participant based on experimentally derived data from ex vivo testing in the participant's tissue sample. Optimal drugs from a pre-specified drug pool will be recommended by the QPOP team.
CURATE.AI - a small data, AI-derived technology platform based on this discovery - allows personalised guidance of an individual's dose modulations based only on that individual's data. Additionally, CURATE.AI is mechanism-independent, and dynamically adapts to changes experienced by the participant, providing dynamic dose optimisation throughout the duration of the participant's treatment. The second stage of the trial aims to obtain a personalised CURATE.AI profile for each participant, based on their phenotypic response to a set of drug doses from the drug combinations with azacitidine identified and recommended by the QPOP team. The doses will be recommended by the CURATE.AI team, when relevant to the clinical decision-making process. Once an actionable profile is obtained, dose recommendations are based on the profile and aimed to treat the participant. The maximum period of involvement with this study when azacitidine may be adjusted by CURATE.AI is 18 months.
Azacitidine subcutaneous injection Day 1, 2 and Day 8, 9 + 30 mg/m2 docetaxel intravenously Day 1 and 8 Each chemotherapy cycle will be 21 days.
Azacitidine subcutaneous injection Day 1, 2 and Day 8, 9 + 80 mg/m2 paclitaxel intravenously Day 1 and 8 Each chemotherapy cycle will be 21 days.
Azacitidine intravenously subcutaneous injection Day 1, 2 and Day 8, 9 + 100 mg/m2 irinotecan intravenously Day 1 and 8. Each chemotherapy cycle will be 21 days.
