Phase I Study of Epacadostat (INCB024360) Added to Preoperative Chemoradiation in Patients With Locally Advanced Rectal Cancer

The purpose of this research study is to evaluate epacadostat when given with routine
radiation therapy and chemotherapy (capecitabine and oxaliplatin) to treat rectal cancer
before routine surgery is performed to remove the tumor.


Inclusion Criteria:

- Newly diagnosed locally advanced rectal cancer with pathology confirmation as
determined by any one of the below:

- Clinical stage (c) T4a, i.e. overgrowth to an adjacent organ or structure like
the prostate, urinary bladder, uterus, sacrum, pelvic floor, or side wall
(according to TNM version 5)

- cT4b, i.e. peritoneal involvement

- Extramural vascular invasion (EMVI+)

- N2, i.e. four or more lymph nodes in the mesorectum showing morphological signs
on MRI indicating metastatic disease

- Positive MRF, i.e. tumor 1 mm or less from the mesorectal fascia.

- Metastatic lateral nodes, > 1 cm (lat LN+)

- At least 18 years of age.

- ECOG performance status ≤ 1

- Normal bone marrow and organ function as defined below:

- Absolute neutrophil count ≥ 1,500/mcl

- Platelets ≥ 100,000/mcl

- Hemoglobin > 9 g/dL

- Total bilirubin ≤ IULN

- AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN

- Serum creatinine < 1.5 x IULN OR measured or calculated creatinine clearance ≥ 50
mL/min/1.73 m2

- INR or PT ≤ 1.5 x IULN unless patient is receiving anticoagulant therapy as long
as INR or PTT is within therapeutic range of intended use of anticoagulants

- aPTT ≤ 1.5 x IULN unless patient is receiving anticoagulant therapy as long as
INR or PTT is within therapeutic range of intended use of anticoagulants

- Willing to undergo study-related biopsies subject to accessibility of tumor,
appropriateness of biopsy (not contraindicated), and continued subject consent.

- Women of childbearing potential and men must agree to contraceptive methods as
described in protocol prior to study entry, for the duration of study participation,
and for 120 days after the last dose of study treatment. Should a woman become
pregnant or suspect she is pregnant while participating in this study, she must inform
her treating physician immediately.

- Able to understand and willing to sign an IRB approved written informed consent
document (or that of legally authorized representative, if applicable).

Exclusion Criteria:

- Received prior anti-cancer therapy for rectal cancer.

- Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or
anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibody (including
ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation
or checkpoint pathways) or other agents targeting IDO pathway (including indoximod)

- Previous radiotherapy in the pelvic region or previous rectal surgery (e.g. TEM) or
any investigational treatment for rectal cancer within the past month.

- A history of prior malignancy active within the previous 3 years except for locally
curable cancers that have been apparently cured, including, but not limited to, basal
or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the
prostate, cervix, or breast.

- Currently receiving any other investigational agents.

- Extensive growth into cranial part of the sacrum (above S3) or the lumbosacral nerve
roots indicating that surgery will never be possible even if substantial tumor
downsizing is seen.

- Presence of metastatic disease or recurrent rectal tumor.

- Diagnosis of Familial Adenomatosis Polyposis coli (FAP), Hereditary Non-Polyposis
Colorectal Cancer (HNPCC), active Crohn's disease, or active ulcerative colitis.

- A history of allergic reactions attributed to compounds of similar chemical or
biologic composition to epacadostat, pembrolizumab, 5-FU, oxaliplatin, or other agents
used in the study.

- Has an active infection requiring systemic therapy.

- Warfarin (Coumadin): patients currently on warfarin are excluded

- Any history of serotonin syndrome (SS) after receiving serotonergic drugs.

- Uncontrolled intercurrent illness including, but not limited to symptomatic congestive
heart failure, unstable angina pectoris, or cardiac arrhythmia.

- Active infection requiring systemic therapy.

*Has an active or inactive autoimmune disease or syndrome (i.e. rheumatoid arthritis,
moderate or severe psoriasis, multiple sclerosis, inflammatory bowel disease) that has
required systemic treatment in the past 2 years or is receiving systemic therapy for
an autoimmune or inflammatory disease (i.e. with use of modifying agents,
corticosteroids, or immunosuppressive drugs).

- Exceptions include subjects with vitiligo or resolved childhood asthma/atopy,
hypothyroidism stable on hormone replacement, controlled asthma, Type I diabetes,
Graves' disease, or Hashimoto's disease.

- Presence of an abnormal ECG that, in the investigator's opinion, is clinically
meaningful.

- Presence of a gastrointestinal condition that may affect drug absorption.

- Receipt of live attenuated vaccine within 30 days before the first dose of study
treatment. Examples of live vaccines include, but are not limited to, the following:
measles, mumps, rubella, chicken pox, yellow fever, rabies, Bacillus Calmette-Guérin
(BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally
killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g.
FluMist) are live attenuated vaccines and are not allowed.

- Pregnant and/or breastfeeding. Women of childbearing potential must have a negative
pregnancy test within 72 hours of study entry.

- Evidence of interstitial lung disease or active, non-infectious pneumonitis including
symptomatic and/or pneumonitis requiring treatment

- Known history of active TB.

- Known HIV-positivity (HIV 1/2 antibodies).

- Known active hepatitis B (e.g. HBsAg reactive or HBV DNA detected) or hepatitis C
(e.g. HCV RNA [qualitative] is detected) infection. Testing at screening is required.
