| Eligibility |
Inclusion Criteria:
- Patients must have histologically proven adenocarcinoma of the rectum with no evidence
of distant metastases.
- The tumor must be clinically Stage II (T3-4 N0) or stage III (N+). Stage of the tumor
may be determined by CT scan, endorectal ultrasound or MRI. (For patients receiving
chemotherapy prior to protocol chemoradiation, the initial clinical stage applies.
CT/MRI/PET should be performed within 2 months of study entry to exclude disease
progression.). For the MTD expansion phase only: patients who are stage IV, and in
whom it is planned to administer capecitabine and radiation then have a resection of
their rectal cancer, are also eligible.
- Measurable disease not required at baseline. Patient's without measurable disease may
be enrolled as long as they clinically meet stage II or III criteria or for MTD
expansion phase: also stage IV.
- Patients must not have received pelvic radiation for rectal cancer, or prior pelvic
radiation for any other malignancy that would prevent the patient from receiving the
required radiation treatments for this study. (Patients may receive neoadjuvant
chemotherapy prior to study chemoradiation)
- Patients must not have an active concurrent invasive malignancy. Patients with prior
malignancies, including invasive colon cancer, are eligible if they are deemed by
their physician to be at low risk for recurrence. For example, patients with squamous
or basal cell carcinoma of the skin, melanoma in situ, carcinoma of the cervix, or
carcinoma in situ of the colon or rectum that have been effectively treated are
eligible, even if these conditions were diagnosed within 3 years prior to
registration.

Exclusion Criteria:
- Patient has a known hypersensitivity to any of the excipients of BYL719 (alpelisib)
- Suspected or confirmed metastatic disease including CNS involvement. For stage IV
patients: CNS involvement.
- Patient with clinically manifest diabetes mellitus, or documented steroid induced
diabetes mellitus
- Patient with impaired gastrointestinal (GI) function or GI disease that may
significantly alter the absorption of oral BYL719 (e.g. ulcerative disease,
uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel
resection). Patients with colostomies are allowed unless colostomy is for one of the
precluded reason above.
- Patient who has not recovered to grade 1 or better (except alopecia) from related side
effects of any prior antineoplastic therapy
- Patient who has had systemic therapy within 4 weeks of starting study treatment (6
weeks for nitrosoureas or mitomycin C)
- Patient who has undergone major surgery = 4 weeks prior to starting study treatment or
in the investigators opinion who has not recovered from side effects of such procedure
- Patient has any of the following cardiac abnormalities: A. symptomatic Congestive
heart failure i. history of documented congestive heart failure (New York Heart
Association functional classification III-IV), documented cardiomyopathy ii. Left
Ventricular Ejection Fraction (LVEF) <50% as determined by Multiple Gated acquisition
(MUGA) scan or echocardiogram (ECHO) B. myocardial infarction < 6 months prior to
enrollment C. unstable angina pectoris D. serious uncontrolled cardiac arrhythmia E.
symptomatic pericarditis F. QTcF > 480 msec on the screening ECG (using the QTcF
formula)
- Patient who is currently receiving medication with a known risk of prolonging the QT
interval or inducing Torsades de Pointes (TdP) and the treatment cannot either be
discontinued or switched to a different medication prior to starting study drug
treatment. To be documented and submitted to BrUOG with registration. Please refer to
appendices F and G.
- Patient who has participated in a prior investigational cancer treatment study within
30 days prior to enrollment. This refers to treatment not follow-up.
- Patient is currently receiving warfarin or other coumarin derived anti-coagulant, for
treatment, prophylaxis or otherwise. Therapy with heparin, low molecular weight
heparin (LMWH), or fondaparinux is allowed. To be documented and submitted to BrUOG
with registration. Eliquis is allowed.
- Patient is currently receiving treatment with drugs known to be strong inhibitors or
inducers of isoenzyme CYP3A. The patient must have discontinued strong inducers for at
least one week and must have discontinued strong inhibitors before the start of
treatment. Switching to a different medication prior to registration is allowed;
(Refer to Section Concomitant Medication, Appendix F and G).
- Patient with known positive serology for human immunodeficiency virus (HIV)
- Patient with any other condition that would, in the Investigator's judgment, preclude
patient's participation in the clinical study due to safety concerns or compliance
with clinical study procedures, e.g. infection/inflammation, intestinal obstruction,
unable to swallow oral medication, social/psychological complications, chronic active
hepatitis, severe hepatic impairment etc
- Patients who have other concurrent severe and/or uncontrolled medical conditions that
would, in the Treating Physician's judgment, contraindicate patient participation in
the individual patient program (eg. active or uncontrolled severe infection, chronic
active hepatitis, immuno-compromised, acute or chronic pancreatitis, uncontrolled high
blood pressure, interstitial lung disease, etc.)
- Patient has a history of non-compliance to medical regimen or inability to grant
consent
- Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a
female after conception and until the termination of gestation, confirmed by a
positive hCG laboratory test (> 5 mIU/mL). Pregnancy test not required for patients
who are considered post-menopausal and not of childbearing potential as defined below.
Women are considered post-menopausal and not of child-bearing potential if they have had 12
months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age
appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy
(with or without hysterectomy) at least six weeks ago.
For women with therapy-induced amenorrhea, oophorectomy or serial measurements of FSH
and/or estradiol are needed to ensure postmenopausal status.
- Patient who does not apply highly effective contraception during the study and through
the duration as defined below after the final dose of study treatment:
1. Sexually active males (unless surgically sterilized at least 6 months prior to
screening) should use a condom during intercourse while taking drug and for 6
months after the final dose of study treatment and should not father a child in
this period, but may be recommended to seek advice on conservation of sperm. The
use of spermicidal foam is also highly suggested to be used with a condom as
another form of protection. A condom is required to be used also by vasectomized
men in order to prevent delivery of the drug via seminal fluid. Males should be
cautioned to not donate sperm while actively receiving treatment on study.
2. Women of child-bearing potential, defined as all women physiologically capable of
becoming pregnant, must use highly effective contraception during the study and
through 6 months after the final dose of study treatment.
- Herbal preparations/medications are not allowed throughout the study. These herbal
medications include, but are not limited to: St. John's wort, Kava, ephedra (ma
huang), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto, Medical
Marijuana and ginseng. Patients need to stop using these herbal medications 7 days

juice, grapefruit hybrids, pummelos, starfruits and cranberry juice from 7 days prior
to the first dose of study drug and during the entire study treatment
- Patient is currently receiving or has received systemic corticosteroids < 2 weeks
prior to day 1 of study drug, or who has not fully recovered from side effects of
treatment. The following uses of corticosteroids are permitted: single doses, topical
applications (e.g., for rash), inhaled sprays (e.g., for obstructive airways
diseases), eye drops or local injections (e.g., intra-articular).
- Patient is concurrently using other anti-cancer therapy
