Regorafenib

Tanios Bekaii-Saab

This randomized phase II trial studies how well lower-dose compared to standard dose regorafenib works in treating patients with colorectal cancer that has spread from the primary site (place where it started) to other places in the body and does not respond to treatment. Regorafenib may stop the growth of colorectal cancer by blocking the growth of new blood vessels necessary for tumor growth and by blocking some of the enzymes needed for cell growth. It is not yet known whether lower-dose or standard dose regorafenib is more effective in treating patients with colorectal cancer. Clobetasol propionate is a steroid cream that is commonly used to treat a variety of skin conditions and may help prevent hand-foot skin reactions in patients receiving regorafenib.

PRIMARY OBJECTIVES:

I. Evaluate the proportion of patients who complete 2 cycles of protocol treatment and initiate cycle 3 in arm A (pooled arm A1 and A2) and arm B (pooled arm B1 and B2).

SECONDARY OBJECTIVES:

I. Evaluate outcome measures for efficacy in each arm including progression-free survival (PFS), time to progression (TTP), and overall survival (OS).

II. Compare between arms the cumulative dose and dose intensity received within the first two cycles.

III. Evaluate the proportion of patients in each arm that exhibit grade 3 palmar-plantar erythrodysesthesia syndrome (PPES) and/or fatigue, and make comparisons between regorafenib dosing strategies and pre-emptive versus (vs.) reactive strategies to address PPES.

IV. Compare quality of life (QOL) between treatment arms (regorafenib dosing strategies and preemptive vs. reactive PPES strategies) as measured by the Hand and Foot Syndrome (HFS)14, Brief Fatigue Inventory (BFI), and Linear Analogue Self-Assessment (LASA) questionnaires.

TERTIARY OBJECTIVES:

I. Evaluate and compare trough minimum concentration (Cmin) pharmacokinetics (PK) during the first 2 treatment cycles for regorafenib and active metabolites M2, M5 between the low dose (dose escalation) and the standard dose cohorts, and correlate with toxicity profile.

II. Evaluate the correlation between PK parameters and tumor response/stable disease after the first two cycles.

III. Evaluate the correlation between PK parameters and PFS and OS. IV. Evaluate if trough (Cmin) concentrations are associated with patient-specific factors (such as ? but not limited to ? age and concomitant medications).

OUTLINE: Patients are randomized to 1 of 4 treatment arms.

ARM A1: Patients receive lower-dose regorafenib PO once daily (QD) on days 1-21 and pre-emptive clobetasol propionate given topically twice daily (BID) for 12 weeks, beginning on day 1 of regorafenib.

ARM A2: Patients receive lower-dose regorafenib PO as in Arm A1 and reactive clobetasol propionate given topically BID beginning on day 1 per physician discretion upon occurrence of PPES grade \>= 1.

ARM B1: Patients receive standard dose regorafenib PO QD on days 1-21 and pre-emptive clobetasol propionate as in Arm A1.

ARM B2: Patients receive standard dose regorafenib PO as in Arm B1 and reactive clobetasol propionate as in Arm A2.

In all arms, courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 2-6 months.

Lower or Standard Dose Regorafenib in Treating Patients With Refractory Metastatic Colorectal Cancer

Regorafenib Dose Optimization Study (ReDOS): A Phase II Randomized Study of Lower Dose Regorafenib Compared to Standard Dose Regorafenib in Patients With Refractory Metastatic Colorectal Cancer (mCRC)

After quantitation, the average trough concentration, calculated from all available data, will be calculated. This average trough concentration will be correlated with toxicity and efficacy endpoints. Further descriptive characteristics of the pharmacokinetics will also be calculated, an example includes (but is not limited to) within-patient variability in the trough concentrations pharmacokinetic parameters will also be calculated, both overall and within courses, as a ratio of the maximum:minimum value.

Fisher exact test will be used to detect a difference course 3 between arms (starting low dose \[pooled arm A1 and A2\] versus \[vs.\] standard dose \[pooled arm B1 and B2\]). The proportion of patients who complete 2 courses of protocol treatment and initiate course 3 will be computed by arm with its 95% confidence interval using exact method.

OS is defined as the time from randomization to death due to any cause and will be estimated with Kaplan-Meier survival curves and differences between regorafenib arms (A vs. B) tested using log-rank tests, though these analyses are not powered for formal non-inferiority assessments.

PFS is defined as the time from randomization to the earlier of disease progression or death due to any cause, where progressed disease (PD) is defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and will be estimated with Kaplan-Meier survival curves and differences between regorafenib arms (A vs. B) tested using log-rank tests, though these analyses are not powered for formal non-inferiority assessments.

TTP is defined as the time from randomization to disease progression, where PD is defined by RECIST 1.1 and will be estimated with Kaplan-Meier survival curves and differences between regorafenib arms (A vs. B) tested using log-rank tests, though these analyses are not powered for formal non-inferiority assessments.

Will be summarized with descriptive statistics and compared between regorafenib arms (A vs. B).

Dose intensity of regorafenib received by patients in the first two cycles as measured by the percentage (%) of planned dose received

Will be computed with 95% confidence intervals, and differences between regorafenib dosing strategies (pooled across HFS strategies) tested using a Fisher Exact test. The incidence of grade 3 or 4 HFS will also be descriptively compared between those receiving a pre-specified preemptive vs. reactive approach for hand and foot syndrome (pooled across dosing strategies), and tested using a Fisher Exact test.

Patients will be descriptively compared between treatment arms and between HFS treatment strategies (pre-emptive vs. reactive) according to self-reported outcomes given on the HFS14 questionnaire. Results from the course 1 and 2 HSF14 questionnaires will also be summarized descriptively as they relate to the pre-emptive versus reactive palmar-plantar erythrodysesthesia syndrome (PPES) strategies, with comparisons made within and between arms using the t-test or Wilcoxon rank sum test as appropriate, as well as taking time-dependence into account.

Changes in QOL (according to the LASA questionnaire as measured by the overall QOL question) from baseline will be compared between the treatment arms using the Kruskal-Wallis test.

Each CTCAE term is a representation of a specific event used for medical documentation \& analysis \& is a single MedDRA Lowest Level Term (LLT). All graded AEs are reported for non-cancel patients. Serious AE (SAE) reports may include any secondary serious or non-serious events considered related to the primary event (the reason for filing an expedited report); collectively, these events are referred to as Expedited AEs, \& appear in the SAE table.

In the regorafenib dose escalation group, the starting dose of regorafenib was 80 mg/day in week 1, 120 mg/day in week 2, and 160 mg/day in week 3 for cycle 1. Weekly incremental dose-escalation occurred if no significant drug-related toxicities (SDRTs) were observed. In cycle 2, patients received the highest tolerated dose from cycle 1. Patients also received prophylactic 0.05% clobetasol cream twice daily applied to palms and soles starting at cycle 1 day 1 for prevention of HFSR (pre-emptive strategy).

Arm A1 (Regorafenib Dose Escalation + Pre-emptive Strategy)

In the regorafenib dose escalation group, the starting dose of regorafenib was 80 mg/day in week 1, 120 mg/day in week 2, and 160 mg/day in week 3 for cycle 1. Weekly incremental dose-escalation occurred if no significant drug-related toxicities (SDRTs) were observed. In cycle 2, patients received the highest tolerated dose from cycle 1. Patients also had the clobetasol cream applied when HFSR developed (reactive strategy).

Arm A2 (Regorafenib Dose Escalation + Reactive Strategy)

In the regorafenib standard dose group, the regorafenib dose schedule of 160 mg/day started on day 1 and continued for 21 every 28 days. The dose of 160 mg as the standard dose was used since it is the approved and most commonly used dose/schedule in clinical practice based on the results of randomized trials. Patients also received prophylactic 0.05% clobetasol cream twice daily applied to palms and soles starting at cycle 1 day 1 for prevention of HFSR (pre-emptive strategy).

Arm B1 (Regorafenib Standard Dose + Pre-emptive Strategy)

In the regorafenib standard dose group, the regorafenib dose schedule of 160 mg/day started on day 1 and continued for 21 every 28 days. The dose of 160 mg as the standard dose was used since it is the approved and most commonly used dose/schedule in clinical practice based on the results of randomized trials. Patients also had the clobetasol cream applied when HFSR developed (reactive strategy).

Arm B2 (Regorafenib Standard Dose + Reactive Strategy)

In the regorafenib standard dose group, the regorafenib dose schedule of 160 mg/day started on day 1 and continued for 21 every 28 days. The dose of 160 mg as the standard dose was used since it is the approved and most commonly used dose/schedule in clinical practice based on the results of randomized trials.Patients also received prophylactic 0.05% clobetasol cream twice daily applied to palms and soles starting at cycle 1 day 1 for prevention of HFSR (pre-emptive strategy).

Leucovorin Calcium

Laboratory Biomarker Analysis

Afsaneh Barzi, MD

This randomized trial studies how well panitumumab, leucovorin calcium, and fluorouracil after combination chemotherapy and panitumumab induction work in treating patients with RAS wild type colorectal cancer that has spread from where it started to nearby tissue or lymph nodes or other places in the body or cannot be removed by surgery. Monoclonal antibodies, such as panitumumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving panitumumab, leucovorin calcium, and fluorouracil after combination chemotherapy and panitumumab induction may work better in treating patients with colorectal cancer.

PRIMARY OBJECTIVES:

I. To compare the duration of progression free survival 1 (PFS1) in patients with RAS wild type who have received induction leucovorin calcium, fluorouracil, and oxaliplatin (FOLFOX) + panitumumab and not progressed at 6 cycles and randomized to maintenance therapy with fluorouracil (5FU) based therapy with or without panitumumab.

SECONDARY OBJECTIVES:

I. To compare the response rate (RR) in patients with RAS wild type who are randomized to maintenance therapy with 5FU based therapy to those randomized to 5FU based therapy with panitumumab.

TERTIARY OBJECTIVES:

I. Progress free survival 2 (PFS2). II. To assess the adverse event (AE) profile and safety of the proposed treatment in this population.

III. To assess and compare the overall survival (OS) between the two treatment groups.

IV. To compare the quality of life (QOL) as measured by health state index (HIS) between patients who achieve partial response (PR) versus (vs.) those who progress and those who have stable disease during the induction phase.

V. To compare the QOL as measured by HSI between the two groups randomized to maintenance therapy.

VI. To assess the evolution of RAS mutation under treatment during induction phase as well as maintenance.

VII. To explore relationship between genomic and proteomic alterations of the tumor with response and PFS to panitumumab.

OUTLINE:

INDUCTION:

Patients receive panitumumab intravenously (IV) over 30-60 minutes, oxaliplatin IV over 2 hours, leucovorin calcium IV, and fluorouracil over 46-48 hours on day 1. Treatment repeats every 14 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients who are not candidates for surgery, have no disease progression, or do not have complete response after Induction are randomized to 1 of 2 arms.

ARM I: Patients receive panitumumab IV over 30 minutes, leucovorin calcium IV, and fluorouracil over 46-48 hours on day 1. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

Chloe Atreya, MD, PhD

This phase II trial studies the side effects and best dose of capecitabine when given together with pembrolizumab and bevacizumab, and investigates how well they work in treating patients with microsatellite stable colorectal cancer that has spread to nearby tissues or lymph nodes, has spread to other places in the body, or that cannot be removed by surgery. Monoclonal antibodies, such as pembrolizumab and bevacizumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving capecitabine together with pembrolizumab and bevacizumab may work better in treating patients with colorectal cancer.

PRIMARY OBJECTIVES:

I. To determine the recommended phase 2 dose (RP2D)/maximum tolerated dose (MTD) of capecitabine when administered with pembrolizumab and bevacizumab. (Safety Lead-In Cohort) II. To evaluate the overall response rate (ORR) to pembrolizumab plus capecitabine and bevacizumab (complete or partial response rate per Response Evaluation Criteria in Solid Tumors \[RECIST\] 1.1) in subjects with metastatic or locally advanced unresectable microsatellite stable (MSS)/mismatch repair proficient (pMMR) colorectal carcinoma (CRC) that is stable or progressing on fluorouracil (5FU)-based therapy. (Phase II Expansion Cohort)

SECONDARY OBJECTIVES (Phase II Expansion Cohort):

I. To determine the safety and tolerability of pembrolizumab in combination with capecitabine and bevacizumab.

II. To evaluate ORR per immune-related RECIST (irRECIST). III. To evaluate duration of response (DOR), disease control rate (DCR) and progression-free survival (PFS) per RECIST 1.1 and irRECIST and overall survival (OS).

EXPLORATORY OBJECTIVES:

I. Correlation of outcomes to line of therapy; stable disease or progression on a prior regimen containing infusional 5-FU or capecitabine; prior exposure to bevacizumab; and primary tumor location.

II. To explore baseline immune profiles via PD-L1, and multiplex Immunohistochemistry (IHC) for identification of potentially predictive biomarkers in patients with metastatic or locally advanced, unresectable CRC treated with pembrolizumab-based combination therapy.

III. To characterize the change in the populations of tumor-infiltrating immune cells (TIICs) by IHC induced by pembrolizumab-based combination therapy in paired pre- and on-treatment tumor biopsies from patients with metastatic or locally advanced, unresectable MSS / pMMR CRC.

IV. To determine the change in T cell repertoire via next generation sequencing (NGS) within blood and tumor biopsy samples induced by pembrolizumab-based combination therapy in patients with metastatic or locally advanced, unresectable MSS/pMMR CRC.

V. To establish human immune system (HIS) patient-derived xenograft (PDX) models from pre-treatment biopsies to a) analyze change in immune cell profiles HIS PDX models using the same techniques as described for corresponding patients, above and b) correlate response to pembrolizumab-containing therapy in patients and HIS PDX.

OUTLINE:

An initial safety lead-in will be performed to define the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D). Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1, bevacizumab IV over 30-90 minutes on day 1, and capecitabine orally (PO) twice daily (BID) on days 1-14. Treatment repeats every 3 weeks for up to 35 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, every 9 weeks until disease progression, start of new anti-cancer therapy, death, or end of the study whichever comes first
