Sponsored by iOMEDICO AG · Observational
FRUQUENT is an observational study in Germany. The goal of the study is to evaluate how well Fruquintinib works to treat patients with metastatic colorectal cancer that have previously been treated with available standard therapies.
To this end, it will be analyzed how well patients respond to the therapy in the clinical routine. Further points of interest to the study are survival data, safety data, the use of medical care facilities, and the quality of life of patients treated with Fruquintinib.
Participants will be treated as decided by the treating physician and according to their routine practice.
FRUQUENT is accompanied by a translational research project combining real-world clinical data with foundational research to stratify patient collectives in regards to the therapeutic benefit of fruquintinib.
FRUQUENT is a prospective, multicenter, observational study in Germany, collecting real-world data of patients with metastatic colorectal cancer (mCRC) who receive fruquintinib according to the SmPC. The goal of the study is to analyze the effectiveness of the monotherapy with fruquintinib in adult patients with mCRC that have previously been treated with available standard therapies, including fluoropyrimidine, oxaliplatin-, and irintecan-based chemotherapies, anti-VEGF agents, and, if RAS wild-type, anti-EGFR agents. Moreover, the patients must have progressed on or be intolerant to treatment with either trifluridine/tipiracil or regorafenib.
All data for FRUQUENT will be obtained in routine clinical practice, allowing for a representative evaluation of the effectiveness of fruquintinib in a real-world setting. The study aims to recruit 150 patients in 50 practices (office based, oncology outpatient-centers or hospitals) to facilitate robust data.
The companion translational research project "FRUQUENT FUTURE" aims to identify patient collectives that benefit the most from a therapy with fruquintinib. To this end, archival tumor tissue and whole blood from routine blood draws is collected. Real-world clinical data on effectiveness is correlated with biomarker profiles of tumor tissues to determine biomarkers that are indicative of a response to fruquintinib. Longitudinal monitoring of circulating tumor DNA (ctDNA) will allow for an investigation of ctDNA as an indicator of benefit and response to fruquintinib.

Real-world disease control rate (RW DCR)
The primary objective is to assess the effectiveness of fruquintinib in routine treatment. To this end, the real-world disease control rate will be analyzed, defined as the rate of complete response, partial response, or stable disease, either radiologically documented or clinically assessed by the treating physician.
Time frame: Start of treatment to end of treatment (avg. 6 months)
Best response
Further effectiveness objective: Best response radiologically documented or clinically assessed by the treating physician.
Time frame: Start of treatment to end of treatment (avg. 6 months)
Overall response rate (ORR)
Further effectiveness objective: ORR is defined as proportion of patients with any response (partial or complete remission) overall, radiologically documented or clinically assessed by the treating physician.
Time frame: Start of treatment to end of treatment (avg. 6 months)
Time to treatment failure (TTF)
Further effectiveness objective: TTF is defined as the time from treatment start to discontinuation of treatment for any reason, including progression of disease, treatment toxicity, and death.
Time frame: Start of treatment to end of treatment (avg. 6 months)
Time to next treatment (TTNT)
Further effectiveness objective: TTNT is defined as the interval from the start of fruquintinib treatment to initiation of the next line of therapy.
Time frame: Start of treatment to start of subsequent antineoplastic therapy (max. 33 months)
Progression-free survival (PFS)
Further effectiveness objective: PFS is defined as the time from start of fruiquintinib treatment to disease progression or death from any cause.
Time frame: Start of treatment to disease progression or death (max. 33 months)
Overall survival (OS)
Further effectiveness objective: OS is defined as the time from first administration of fruquintinib to death from any cause.
Time frame: Start of treatment to death (max. 33 months)
Adverse events (AEs) and serious adverse events (SAEs) according to NCI CTCAE
Safety objective: Incidence of (serious) AEs ((S)AEs) as characterized by type, frequency, severity and seriousness.
Time frame: Start of treatment until 30 days after end of fruquintinib treatment (avg. 7 months)
Adverse drug reaction (ADR) and serious adverse drug reactions (SADR) related to fruquintinib
Safety objective: Incidence of (serious) adverse drug reactions ((S)ADRs) as characterized by type, frequency, severity and seriousness.

Quality of life (QoL): Absolute values over time from baseline to end of study
Patient-Reported Outcome (PRO) objective: Evaluation of QoL by validated EORTC QLQ-C30 questionnaire during fruquintinib treatment and follow-up period using absolute values over time from baseline to end of study (EOS). The absolute values over time will be reported on the global health status / quality of life scale, functional scales (physical, role, emotional, cognitive, social) and symptom scales (fatigue, nausea and vomiting, pain, dyspnoea, insomnia, appetite loss, constipation, diarrhoea, financial difficulties). These scales are scored from 0 to 100. For the global health status/QoL, higher scores represent a higher QoL. For functional scales, higher scores indicate a higher/healthier level of functioning, while for symptom scales lower scores indicate a lower level of symptomatology/problems.
Time frame: Baseline to (individual) end of study (max. 33 months)
Quality of life (QoL): Change from baseline over time to end of study
Patient-Reported Outcome (PRO) objective: Evaluation of QoL by validated EORTC QLQ-C30 questionnaire during fruquintinib treatment and follow-up period using changes from baseline over time to end of study (EOS). The changes from the baseline over time will be reported on the global health status / quality of life scale, functional scales (physical, role, emotional, cognitive, social) and symptom scales (fatigue, nausea and vomiting, pain, dyspnoea, insomnia, appetite loss, constipation, diarrhoea, financial difficulties). These scales are scored from 0 to 100 and the change is reported as the difference between the scores at baseline and time of interest. For the global health status/QoL and functional scales, positive values indicate an improvement in quality of life while negative values indicate a deterioration in quality of life. For symptom scales, negative values indicate an improvement in symptom burden and positive values indicate an increase in symptom burden.
Time frame: Baseline to (individual) end of study (max. 33 months)
Quality of life (QoL): Time to definitive deterioration (TTD)
Patient-Reported Outcome (PRO) objective: Evaluation of QoL by validated EORTC QLQ-C30 questionnaire during fruquintinib treatment and follow-up period using the time to definitive deterioration (TTD). The time to definitive deterioration will be reported on the global health status / quality of life scale, functional scales (physical, role, emotional, cognitive, social) and symptom scales (fatigue, nausea and vomiting, pain, dyspnoea, insomnia, appetite loss, constipation, diarrhoea, financial difficulties). These scales are scored from 0 to 100 and the TTD is reported as the period of time until definitive deterioration for each scale.
