Recruitment to phase I of the PANTHER trial is complete.
Phase II, is to evaluate the best overall response rate for AZD8931 + FOLFIRI treatment.
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Metastatic Colorectal Cancer Recurrent Colorectal Cancer | Drug: AZD8931 Drug: Irinotecan Drug: Folinic Acid Drug: Fluorouracil | Phase 2 |
PANTHER is a registered phase I/phase II trial in patients with recurrent or metastatic colorectal cancer.
The phase II part of the study will be a single arm trial. Patients will receive AZD8931 (an EGFR/ERBB inhibitor) in combination with FOLinic acid, Fluorouracil and IRInotecan (FOLFIRI), Treatment will be given in two-weekly cycles. Phase II's primary objective is to evaluate the Best overall response

AZD8931 160 mg bd, on days 1-4, + FOLFIRI in a 2 weekly schedule
|
Drug: AZD8931
160 mg AZD8931 tablets, twice daily on days 1 - 4 of each 2-weekly cycle Drug: Irinotecan 180 mg/m2 (IV infusion) of Irinotecan on day 1 of each 2-weekly cycle - can be given simultaneously with Folinic acid. Drug: Folinic Acid 350 mg (IV infusion) of Folinic acid on day 1 of each 2-weekly cycle - can be given simultaneously with Irinotecan. Drug: Fluorouracil 400 mg/m2 (IV bolus) of Fluorouracil on day 1 of each 2-weekly cycle, to be given after completion of Irinotecan and Folinic acid. Drug: Fluorouracil 2400 mg/m2 (IV) continuous infusion of Fluorouracil given over 46 hours - infusion to start after 5FU bolus. |
- Best overall response [ Time Frame: From registration to date of documented best response, assessed up to 36 months ]Best overall response will be assessed according to RECIST v1.1.
- To evaluate the efficacy of AZD8931 plus FOLFIRI [ Time Frame: Baseline to 12 weeks post treatment start ]Percentage change in tumour size will be considered the best response only if a second assessment has been carried out which confirms SD at least four weeks after trial entry. Assessment will be determined using CT scans performed at baseline, 12 weeks after start of chemotherapy, then every 3 months until disease progression up to 3 years from registration/ randomisation
- Progression Free Survival [ Time Frame: From date of randomisation to date of documented disease progression or death from any cause, whichever comes first, assessed up to 3 years from date of registration/ randomisation ]Progression-free survival time will be calculated from the date of trial entry to the date of documented progression, or death from any cause. In cases where progression is suspected and subsequently confirmed by scans, the date of documented suspected progression will be used.
- Overall Survival [ Time Frame: From date of registration/ randomisation until date of death or date of last follow-up assessment (up to 3 years from date of registration/ randomisation) ]Overall survival time will be calculated from the date of trial entry to the date of death from any cause or end of trial follow-up.
- Occurrence and Severity of Adverse Events [ Time Frame: From date of registration/ randomisation until 30 days after completion of trial treatment (AZD8931 and FOLFIRI) ]Will include all grade 1-5 adverse events
