A Phase 1 Study of Durvalumab, Tremelimumab and Radiotherapy in Recurrent Gynecologic Cancer

This research study is evaluating the safety and effectiveness of 2 immunotherapy drugs in
combination with radiation therapy as a possible treatment for recurrent or metastatic
gynecologic cancer.

The names of the immunotherapy drugs involved in this study are:

- Durvalumab

- Tremelimumab

This research study is a Phase I clinical trial, which tests the safety of an investigational
drug or drugs and also tries to define the appropriate dose and combination of the
investigational drugs to use for further studies. "Investigational" means that the drugs are
being studied but have not been approved by the FDA (the U.S. Food and Drug Administration).

In this study, the combination of durvalumab and tremelimumab is considered to be
investigational and as such has not been approved for this or any cancer.

-- Durvalumab and tremelimumab are immunotherapy drugs that may stop cancer cells from
growing by activating the immune system. The immune system is one of the body's natural
defenses against the growth of cancer cells. AstraZeneca has evaluated the effectiveness and
side effects of both durvalumab and tremelimumab individually for many cancer types,
including lung, head and neck cancer, and melanoma. These types of immunotherapy drugs are
also being studied in ovarian, endometrial and cervical cancer. In addition, AstraZeneca has
studied the combination of durvalumab and tremelimumab in participants with lung and
pancreatic cancers. Based on these studies, AstraZeneca has determined the dosing, schedule
and expected side effects for the 2 study drugs when delivered together.

In women with recurrent or metastatic gynecologic cancer, radiation therapy is often used to
help with symptoms, such as bleeding, pain or swelling. Clinical reports have shown that
radiation treatment can increase the body's response to an immunotherapy drug against tumors
both within and outside the radiation field. This study is the first in which the combination
of durvalumab, tremelimumab and abdominal or pelvic radiation is given to humans. The
investigators hope that this combination with radiation will lead to a better treatment
response to the immunotherapy drugs.

The investigators will also look to see if participants whose tumors contain a particular
genetic make-up have a better response to immunotherapy and radiation treatment.

Inclusion Criteria:

- Ability to understand and the willingness to sign a written informed consent document.
Subject is willing and able to comply with the protocol for the duration of the study
including undergoing treatment and scheduled visits and examinations including follow
up.

- Participants must have histologically or cytologically confirmed endometrial, ovarian
(including ovarian epithelial, fallopian tube, primary peritoneal), cervical, vaginal,
or vulvar cancer that is metastatic or unresectable and for which standard curative or
palliative measures do not exist or are no longer effective.

- Participants must have measurable disease, defined as at least 1 lesion that can be
accurately measured in at least one dimension (longest diameter to be recorded for
non-nodal lesions and short axis for nodal lesions) as ≥20 mm with conventional
techniques or as ≥20 mm with spiral CT scan, MRI, or calipers by clinical exam. See
Section 11 for the evaluation of measurable disease. See also 3.1.10 as all
measurable/target lesions must not be located within the planned radiation field for
the expansion cohort.

- Patients must have progressive disease following prior therapy. Specifically, patients
must have progressed on platinum-based chemotherapy.

- At least 21 days must have elapsed from prior therapy (chemotherapy or radiation).

- Age of 18 years or older. Because no dosing or adverse event data are currently
available on the use of durvalumab in combination with tremelimumab and radiation in
patients <18 years of age, children are excluded from this study.

- ECOG performance status ≤1 (Karnofsky ≥60%, see Appendix A).

- Body weight of greater than 30 kg.

- Participants must have normal organ and marrow function as defined below:

- Hgb >=9g/dl

- Absolute neutrophil count ≥1,500/mcL

- Platelets ≥100,000/mcL

- Total bilirubin <=1.5 x normal institutional limits.

--- This last criterion will not apply to patients with confirmed Gilbert's
syndrome (persistent or recurrent hyperbilirubinemia [predominantly unconjugated
bilirubin] in the absence of evidence of hemolysis or hepatic pathology), who
will be allowed in consultation with their physician.

- AST(SGOT)/ALT(SGPT) ≤3 × institutional upper limit of normal

- Creatinine within normal institutional limits

--- OR

- Creatinine clearance >40 mL/min by the Cockcroft-Gault formula (Cockcroft and
Gault 1976) or by 24-hour urine collection for determination of creatinine
clearance:

- Males:

- Creatinine CL (mL/min) = Weight (kg) x (140 - Age)

- 72 x serum creatinine (mg/dL)

- Females:

- Creatinine CL (mL/min) = Weight (kg) x (140 - Age) x 0.85

- 72 x serum creatinine (mg/dL)

- Patients must have at least one lesion not previously irradiated (and not within a
previously irradiated field) for which palliative radiation to the abdomen and/or
pelvis is potentially indicated and could be safely delivered at the radiation doses
specified in this protocol. This lesion must not be within the CNS (brain or spinal
cord), bone or liver, and must not require urgent or emergent palliative radiation
given the timing of radiation specified on this protocol. Furthermore, this lesion
must be located in the abdomen or pelvis and measure at least 2 cm (minimum dimension)
and no greater than 6 cm (maximum dimension). Palliative radiotherapy would entail
involved-field radiotherapy to a single lesion or region to encompass gross disease;
whole-abdomen radiotherapy would not be permitted. Patients who received prior vaginal
brachytherapy would be permitted to receive palliative pelvic radiation. In the
expansion cohort at the MTD, this lesion must not be the only measurable lesion (as
defined in 3.1.3) so that it is possible to determine the response rate outside of the
radiation treatment field.

- The effects of durvalumab and tremelimumab on the developing human fetus are unknown.
For this reason and because radiation is known to be teratogenic, evidence of
post-menopausal status or negative urinary or serum pregnancy test for pre-menopausal
patients is required. Women will be considered post-menopausal if they have been
amenorrheic for 12 months without an alternative medical cause. The following
age-specific requirements apply:

- Women <50 years of age would be considered post-menopausal if they have been
amenorrheic for 12 months or more following cessation of exogenous hormonal
treatments and if they have luteinizing hormone and follicle stimulating hormone
levels in the post-menopausal range for the institution or underwent surgical
sterilization (bilateral oophorectomy or hysterectomy).

- Women ≥50 years of age would be considered post-menopausal if they have been
amenorrheic for 12 months or more following cessation of all exogenous hormonal
treatments, had radiation-induced oophorectomy with last menses >1 year ago, had
chemotherapy-induced menopause with >1-year interval since last menses, or
underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy
or hysterectomy).

- Women of child-bearing potential who are sexually active with a non-sterilized
male partner must agree to use at least 1 method of highly effective
contraception (hormonal or barrier method of birth control; abstinence) prior to
study entry and for the duration of study participation and for 180 days after
the last dose of therapy. Highly effective methods of contraception, defined as
those that result in a low failure rate (i.e., less than 1% per year) when used
consistently and correctly, are described in section 5.5. Should a woman become
pregnant or suspect she is pregnant while she is participating in this study, she
should inform her treating physician immediately.

Exclusion Criteria

- Prior exposure to immune-mediated therapy, including anti-PD-1, anti-PD-L1 (including
durvalumab) or anti-CTLA-4 directed therapy (including tremelimumab). Therapeutic
anticancer vaccines are not included in this category. Exposure to other
investigational agents may be permitted after discussion with the Study PI.

- Chemotherapy, targeted therapy, biologic or hormonal agents within 3 weeks prior to
entering the study.

- Radiation therapy within 3 weeks prior to entering the study.

- Current receipt of any other investigational agents.

- Any unresolved toxicity of NCI CTCAE Grade ≥2, including electrolyte abnormalities,
from previous anticancer therapy, with the exception of alopecia, vitiligo, and the
laboratory values defined in the inclusion criteria.

- Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after
consultation with the Study Physician.

- Patients with irreversible toxicity not reasonably expected to be exacerbated by
treatment with durvalumab or tremelimumab may be included only after consultation
with the Study Physician.

- Patients with untreated brain metastases, spinal cord compression, or leptomeningeal
carcinomatosis are excluded from this clinical trial because of their poor prognosis,
because of symptoms that may arise from inflammatory reactions, and because they often
develop progressive neurologic dysfunction that would confound the evaluation of
neurologic and other adverse events. Patients with brain metastases or spinal cord
compression previously treated with radiation and/or surgery are allowed if local
treatment was >30 days ago, most recent MRI demonstrates stability or decrease in size
of all lesions, and the patient has no current neurologic symptoms related to the
metastases and treatment and no requirement for corticosteroids related to the prior
treatment.

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to tremelimumab and durvalumab or previous toxicity attributed to
durvalumab or other PD-1 or PD-L1 directed therapy that led to drug discontinuation.

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, uncontrolled hypertension, interstitial lung disease, pneumonitis, active
peptic ulcer disease or gastritis, active bleeding diatheses, or serious chronic
gastrointestinal conditions associated with diarrhea.

- Pregnant women are excluded from this study because durvalumab and tremelimumab are
immune checkpoint inhibitors with the potential for teratogenic or abortifacient
effects, as is radiation therapy.

- A nursing mother unwilling to discontinue breastfeeding. Because there is an unknown
but potential risk for adverse events in nursing infants secondary to treatment of the
mother with durvalumab, tremelimumab and radiation, breastfeeding should be
discontinued if the mother is treated with durvalumab, tremelimumab and radiation.

- Female patients who are pregnant or breastfeeding or female patients of reproductive
potential who are not willing to employ effective birth control from screening to 180
days after the last dose of durvalumab + tremelimumab combination therapy or 90 days
after the last dose of durvalumab monotherapy, whichever is the longer time period

- HIV-positive patients are ineligible due to the risks associated with immune
checkpoint blockade.

- Current or prior use of immunosuppressive medication within 14 days before the first
dose of durvalumab and tremelimumab. The following are exceptions to this criterion:

- Intranasal, inhaled, topical steroids, or local steroid injections (e.g.,
intra-articular injection)

- Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of
prednisone or its equivalent

- Steroids as pre-medication for hypersensitivity reactions (e.g., CT scan
pre-medication)

- Major surgical procedure (as defined by the Investigator) within 28 days prior to the
first dose of immunotherapy. Note: Local surgery of isolated lesions for palliative
intent is acceptable.

- History of allogeneic organ transplantation

- Active or prior documented autoimmune or inflammatory disorders. Patients without
active disease in the last 5 years may be included after consultation with the study
physician. This includes: inflammatory bowel disease, such as Crohn's disease or
ulcerative colitis, and diverticulitis with the exception of diverticulosis;
sarcoidosis syndrome, or other serious GI chronic conditions associated with diarrhea;
systemic lupus erythematosus; Wegener syndrome (granulomatosis with polyangiitis);
myasthenia gravis; Graves' disease; rheumatoid arthritis; hypophysitis; or uveitis.
The following are exceptions to this criterion:

- Vitiligo or alopecia

- Hypothyroidism (e,g,, following Hashimoto syndrome) stable on hormone replacement
or psoriasis not requiring systemic treatment

- Any chronic skin condition that does not require systemic therapy

- Celiac disease controlled by diet alone

- History of another primary malignancy except for:

- Malignancy treated with curative intent and with no known active disease ≥5 years
before the first dose of study drug and of low potential risk for recurrence

- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence
of disease

- Adequately treated carcinoma in situ without evidence of disease (e.g., cervical
cancer in situ)

- Mean QT interval corrected for heart rate (QTc) ≥470 ms calculated from 3 consecutive
electrocardiograms (EKGs) using Fridericia's Correction at baseline or before dosing.
Thereafter, only 1 EKG is required during visits unless an abnormality is found and in
which case, confirmation by triplicate EKGs will be needed.

- History of active primary immunodeficiency

- Known history of previous clinical diagnosis of tuberculosis

- Active infection including hepatitis B (known positive HBV surface antigen [HBsAg]
result) or hepatitis C. Patients with a past or resolved HBV infection (defined as the
presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible.
Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain
reaction is negative for HCV RNA.

- Receipt of live attenuated vaccine within 30 days prior to the first dose of
investigational treatment. Note: patients, if enrolled, should not receive live
vaccine during the study and up to 30 days after the last dose of investigational
treatment.

- Psychiatric illness/social situations that would limit compliance with study
requirements or compromise the ability of the subject to give written informed consent

- Any condition that, in the opinion of the Investigator, would interfere with
evaluation of the investigational treatment or interpretation of patient safety or
study results.
