Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants will receive an intravenous infusion of CRLX301 once every 3 weeks or once a week.
The dosage of CRLX301 will be dependent on the cohort to which the participant is recruited. In Phase I, participants will be recruited to dose escalation cohorts in a step wise manner at increasing doses of CRLX301 until MTD (maximum tolerated dose). Provisional doses are:

Schedule 1 (once every 3 weeks dosing)
Cohort 1: 7.5 mg/m2
Cohort 2: 15 mg/m2
Cohort 3: 30* mg/m2
Cohort 4: 45* mg/m2
Cohort 5: 60 mg/m2
Cohort 6: 75 mg/m2
Cohort 7: 90 mg/m2
Cohort 8: 105 mg/m2
Cohort 9: 120 mg/m2
Cohort 10 (plus additional cohorts): 135 mg/m2 (increase dose levels by 15 mg/m2 for additional cohorts)
*The Safety Review Committee (SRC) is allowed to dose escalate from 30 mg/m2 to as high as 60 mg/m2.

Schedule 2 (once a week dosing)
Cohort -1: 20 mg/m2
Cohort 1: 25 mg/m2
Cohort 2: 30 mg/m2
Cohort 3: 35 mg/m2
Cohort 4: 40 mg/m2
Cohort 5: 45 mg/m2
Cohort 6: 50 mg/m2
Additional cohorts: increase dose levels by 5 mg/m2 for additional cohorts or as recommended by SRC

In Phase 2a, all subjects will be treated at the dose determined in Phase 1 and cohort recruitment will be dependent on tumor type.

Treatment continues until progression of disease, dose limiting toxicity, or other protocol specified reason for study discontinuation.

Outcomes
Primary outcome [1] 293709 0
To determine the recommended Phase 2 dose (RP2D) of CRLX301 when administered by intravenous (IV) infusion once every 3-weeks or once a week dosing in patients with advanced solid tumor malignancies. This will be assessed by monitoring participants for dose-limiting adverse events (e.g. severely low white blood cell count, elevated liver function tests).
Timepoint [1] 293709 0
End of phase 1 (Dec2015- Jul2016)
Primary outcome [2] 293710 0
To further establish the safety and tolerability of the CRLX301 MTD / RP2D. This will be assessed by monitoring participants adverse events, laboratory tests, vital signs and electrocardiogram. Examples of adverse events could include: decrease in white blood cells, decrease in red blood cells.
Timepoint [2] 293710 0
End of phase 2 (Jan 2017- July 2017). Patients will be monitored for 30 days post last dose of study drug.
Secondary outcome [1] 311645 0
To evaluate the pharmacokinetic (PK) profile of CRLX301 in blood and urine specimens.
Timepoint [1] 311645 0
Blood samples will be collected at:
3-weekly dosing schedule- prior to CRLX301 infusion, 30 and 60 minutes during infusion, 30, 60, 180, 360 minutes after infusion, 1, 2, 7, 14, 21 days after infusion at Cycles 1, 3 and 6. Urine samples will be collected on Day 1 and day 8 of Cycles 1, 3 and 6.
Weekly dosing schedule- prior to CRLX301 infusion, 30 and 60 minutes during infusion, 30, 60, 180, 360 minutes after infusion and 1 day after infusion at weeks 1, 4 and 7. Prior to CRLX301 infusion at weeks 2, 3, 5 and 6.
Urine samples will be collected on Day 1 of weeks 1, 2, 4, 5, 7 and 8.
Secondary outcome [2] 311646 0
To explore preliminary signs of efficacy of CRLX301. This will be assessed via imaging or methodologies consistent with specific tumour type, performed periodically during the study.
Timepoint [2] 311646 0
Every 9 weeks.
Patients will be monitored for the entire duration they are on treatment- until progression of disease, Dose Limiting Toxicity, or other protocol specified reason for study discontinuation

Eligibility
Key inclusion criteria
1. Male or female adult patients older than or equal to 18 years of age
2. Diagnosis of histologically or cytologically confirmed, advanced solid tumour malignancy:
a) For Phase 1: that is refractory to standard therapy and/or for whom no further standard therapy is available, especially for those for whom taxane chemotherapy may be a reasonable therapeutic choice, in the opinion of the Investigator.
b) For Phase 2a: advanced/metastatic tumours considered responsive to taxanes
c) For prostate cancer patients in Phase 2a: that is castration resistant prostate cancer (CRPC*) and has not been previously treated with taxanes but has been treated with abiraterone and/or enzalutamide.
3. For patients enrolled in Phase 2a only: at least one measurable target lesion as defined by RECIST 1.1 criteria for solid tumours, except for patients with advanced prostate cancer (in which case as per the PCWG2 criteria). Tumours within a previously irradiated field should be designated as “non-target” unless progression is documented or a biopsy is obtained to confirm persistence at least 90 days following completion of radiation therapy.
4. If Patient has received:

d) radiation or invasive surgery requiring general anesthesia; it has been more than 30 days prior to first dose
e) chemotherapy with nitrosoureas or mitomycin C; it has been more than 45 days before first dose

12. History of other cancer type, except for cutaneous basal cell or squamous cell carcinoma, or cervical in situ or very low/low risk prostate cancer, within the last 2 years prior to first dose.
13. Uncontrolled concurrent disease or illness including but not limited to:
a. symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia

c. diabetes mellitus

abnormality that may increase the risk associated with study participation or study
drug administration or that may interfere with the interpretation of study results and,
in the judgment of the investigator, would make the patient inappropriate for the
study.
