Clinical Trial Summary

The purpose of this study is to evaluate the safety and efficacy of Abraxane (nab-paclitaxel) in subjects with previously treated metastatic colorectal cancer. Subjects will be placed into two separate cohorts based on their RAS mutation status.

Description:

ABI-007-COLO-001 is a Phase 2, single arm, open label, multicenter study to evaluate the efficacy and safety of Abraxane (nab-paclitaxel) given on days 1, 8 and 15 of a 28 day cycle in subjects with previously treated metastatic colorectal cancer. Subjects will be enrolled into cohorts by RAS mutation status (wildtype or mutated). Stage 1 in a given cohort will enroll 15 subjects in the Intention to Treat population and if more than 8 subjects have Progression Free Survival at the 8 week assessment, then Stage 2 will open in the respective cohort. Stage 2 will enroll an additional 28 subjects for a total of 43 subjects in each cohort. The study will be positive if more than 26 subjects with Progression Free Survival at the 8 week assessment are observed in 43 subjects per cohort. Interim analysis after Stage 1 did not meet protocol defined criteria to proceed to Stage 2. Patients currently enrolled will be followed for Progression Free Survival and until 28 days after last dose, secondary endpoints including overall survival will not be followed

Subject has received radiotherapy = 4 weeks or limited field radiation for palliation = 2 weeks prior to starting Investigational Product, and/or from whom = 30% of the bone marrow was irradiated. Radiation therapy to a target lesion is permitted only if there has been clear progression of the lesion since radiation was completed. 5. Subject has had major surgery within 14 days prior to starting Investigational Product or has not recovered from postoperative complications 6. Subject has not recovered from the acute toxic effects of prior anticancer therapy, radiation or major /significant trauma 7. Subject has a history of allergy or hypersensitivity to nab-paclitaxel or any of the excipients 8. Subject has a known history of the following within 6 months prior to enrollment (the decision to include the subject in the study): a myocardial infarction, severe/unstable angina pectoris, coronary/peripheral artery bypass graft, New York Heart Association Class III-IV heart failure, uncontrolled hypertension, clinically significant cardiac dysrhythmia or Electrocardiogram abnormality, cerebrovascular accident, transient ischemic attack, or seizure disorder 9. Subject has a known infection with hepatitis B or C, or history of human immunodeficiency virus infection, or subject receiving immunosuppressive or myelosuppressive medications that would in the opinion of the investigator, increase the risk of serious neutropenic complications 10. Subject has an active, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy, defined as ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment 11. Subject has any other malignancy within 5 years prior to enrolment, with the exception of adequately treated in-situ carcinoma of the cervix, uteri, or non-melanomatous skin cancer (all treatment of which should have been completed 6 months prior to enrollment) 12. Subject has a history of connective tissue disorders (eg, lupus, scleroderma, arteritis nodosa) 13. Subject has a history of interstitial lung disease , history of slowly progressive dyspnea and unproductive cough, sarcoidosis, silicosis, idiopathic pulmonary fibrosis, pulmonary hypersensitivity pneumonitis or multiple allergies

14. Subject has any other concurrent severe and/or uncontrolled medical condition that would, in the investigator's judgment, contraindicate subject participation in the clinical study (e.g. chronic pancreatitis, chronic active hepatitis, etc.) 15. Subject is enrolled in any other clinical protocol or investigational study with an interventional agent or assessments that may interfere with study procedures 16. Subject has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study 17. Subject has any condition that confounds the ability to interpret data from the study 18. Subject is unwilling or unable to comply with study procedures 19. Subject is a pregnant or nursing female

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Kaplan Meier Estimate of PFS by Investigator Assessment	PFS was measured as time from the date of first dose to the date of disease progression according to RECIST 1.1 or death from any cause, whichever was earlier.	Up to 241 days
Primary	Progression Free Survival (PFS) Rate as Measured at Week 8	PFS rate was measured by Investigator Assessment according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 from the start of study treatment to disease progression or death from any cause, whichever occurred first.	At week 8 assessment period; up to 56 days
Secondary	Percentage of Participants With Stable Disease for = 8 Weeks, or Complete or Partial Response According to RECIST Version 1.1; Disease Control Rate (DCR)	DCR was defined as the combined incidence of stable disease confirmed CR or PR and stable disease (SD) measured at the Week 8 assessment or later.	At week 8 and later; up to day 241
Secondary	Overall Survival	Overall Survival was the time from the first dose of study drug to patient death from any cause.	Up to 241 days
Secondary	Overall Response Rate (ORR)	ORR was defined as the combined incidence of Complete Response (CR) and Partial Response (PR), confirmed no less than 4 weeks after the criteria for response were first met based on RECIST 1.1. Tumor responses were assessed every 2 cycles using RECIST 1.1 and defined as: • Complete response-disappearance of all target lesions • Partial response- At least a 30% decrease in the sum of diameters of target lesions from baseline • Stable disease-neither sufficient shrinkage to qualify for PR nor sufficient increase of lesions to qualify for Progressive disease (PD) • Progressive Disease- At least a 20% increase in the sum of diameters of target lesions from nadir.

Secondary	Duration of Response (DOR)	Duration of response was defined as the time from the first tumor assessment when the confirmed CR/PR response criterion was met to the date of disease progression based on investigational assessment following RECIST 1.1.	Up to 241 days
Secondary	Number of Participants With Adverse Events	A treatment emergent adverse events (TEAE) was defined as any AE occurring or worsening on or after the first dose of study drug and within 28 days after the last dose of study drug. A TESAE is defined as any serious adverse event (SAE) occurring or worsening on or after the first dose of study drug and within 28 days after the last dose of study drug. Safety and Severity was assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 4.0; Severity of AEs were graded (including second primary malignancies) as Grade 1- Mild; Grade 2- Moderate; Grade 3- Severe; Grade 4- Lifethreatening; Grade 5-Fatal;	Time of the first dose of study treatment to 28 days after the last dose of study drug; maximum treatment duration was 24 weeks
