A Phase I/II Study of M3814 and Avelumab in Combination with Hypofractionated Radiation in Patients with Advanced/Metastatic Solid Tumors and Hepatobiliary Malignancies.
Primary Objective:
Phase I:
(1) To determine the safety and tolerability and recommended phase 2 dose (RP2D) of M3814 in combination with hypofractionated radiation and avelumab in patients with advanced/metastatic solid tumors.
Phase II:
(1) To determine the efficacy of the combination of hypofractionated radiation, M3814, and avelumab as compared to the combination of hypofractionated radiation and avelumab in patients with advanced/metastatic hepatobiliary tumors by objective response rate (ORR) in non-irradiated lesions. All lesions (target and non-target) except the one or two lesions that were irradiated are to be included in the assessment of overall response using RECIST v1.1.
Secondary Objective(s):
Phase I:
(1) To observe and record anti-tumor activity. Although the clinical benefit of this combination has not yet been established, the intent of offering this treatment is to provide a possible therapeutic benefit, and thus the patient will be carefully monitored for tumor response and symptom relief in addition to safety and tolerability. Specifically, to determine efficacy of the combination by measurement of disease control rate (DCR), duration of response (DOR), progression free survival (PFS), PFS outside the irradiated field, and overall survival (OS) in patients with advanced/metastatic solid tumors.
(2) To characterize the pharmacokinetic (PK) profile of M3814 in combination with avelumab.
Phase II:
(1) To determine the efficacy and safety of the combination of hypofractionated radiation, M3814, and avelumab as compared to hypofractionated radiation and avelumab by measurement of DCR, DOR, PFS, PFS outside the irradiated field, and OS in patients with advanced/metastatic hepatobiliary tumors.
(2) To determine if baseline DNA repair defects inherent to some cholangiocarcinomas correlate with a more dramatic response to radiation compared to those without as measured by H2AX pNBS1 multiplex IFA assay.
(3) To characterize the pharmacokinetic (PK) profiles of M3814 and avelumab.

Inclusion Criteria
- PHASE 1: Patients must have a histologically confirmed metastatic or locally advanced
unresectable solid tumor that has progressed on or after available standard of care
therapy or for which no acceptable standard of care therapy exists, or in which the
patient declines standard of care therapy (each patient that declines standard of care
therapy will be documented in the case report form)
- PHASE 2: Patients must have a histologically confirmed metastatic or locally advanced
unresectable cholangiocarcinoma/gallbladder carcinoma that has progressed on at least
1 prior standard of care therapy or for which no acceptable standard of care therapy
exists, or in which the patient declines standard of care therapy (each patient that
declines standard of care therapy will be documented in the case report form)
- Age >= 18 years
- Because no dosing or adverse event data are currently available on the use of
M3814 in combination with avelumab in patients < 18 years of age
- Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
- Patients with at least 1 index lesion to irradiate for whom palliative radiation
treatment is indicated (including but not limited to pain and/or symptom control,
prevention of disease -related complications, and preservation of organ function).
Lung and liver lesions are preferred, though alternate lesions may be considered after
discussion with trial principal investigator (PI). Up to 2 lesions may be considered
for irradiation provided at least 1 lesion will receive the study treatment of total
of 60 Gy and all prescribed irradiation will be completed within the radiation window
- Patients with at least 1 Response Evaluation Criteria in Solid Tumors (RECIST)
measurable lesion (to be unirradiated) (defined as those accurately measured in at
least one dimension, with the longest diameter to be recorded for non-nodal lesions
and the shortest diameter for nodal lesions). Measurable is defined as at least 10 mm
in longest diameter for solid tumors, at least 15 mm in shortest diameter for lymph
nodes
- Patients must be willing to undergo fresh biopsies at baseline (as opposed to using
archival tissue), in the event their baseline tissue was obtained > 12 months prior to
study consent and/or they are randomized to the gamma H2AX pNBS1 multiplex IFA assay
- Absolute neutrophil count (ANC) >= 1,500/mcL
- Platelet count >= 100,000/mcL
- Hemoglobin >= 9.0 g/dL
- Serum creatinine =< 1.5 x upper limit of normal (ULN) OR calculated serum creatinine
clearance (glomerular filtration rate [GFR] can be used in place of creatinine or
creatinine clearance) >= 60 mL/min for participants with creatinine levels > 1.5 x
institutional ULN
- Calculate serum creatinine clearance using the standard Cockcroft-Gault formula
- Serum total bilirubin =< 1.5 x ULN or direct bilirubin =< ULN for participants with
total bilirubin > 1.5 x ULN
- Patients with known Gilbert disease with serum bilirubin level =< 3 x ULN are
eligible
- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT]) and
alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x
ULN or =< 5.0 x ULN for patients with hepatobiliary tumors/liver metastases
- Albumin >= 2.8 g/L
- International normalized ratio (INR) or prothrombin time (PT) or activated partial
thromboplastin time (aPTT) =< 1.5 x ULN
- This applies only to patients not receiving therapeutic anticoagulation; patients
receiving therapeutic anticoagulation should be on a stable dose
- Participants must have the ability to swallow and retain oral medication and not have
any clinically significant gastrointestinal abnormalities that might alter absorption
- Female patients of childbearing potential must have a negative urine or serum
pregnancy test within 72 hours prior to receiving the first dose of study medication.
If the urine test is positive or cannot be confirmed as negative, a serum pregnancy
test will be required. The effects of M3814 and avelumab on the developing human fetus
are unknown and there is the potential for teratogenic or abortifacient effects. For
this reason, women and men of child-bearing potential must agree to use adequate
contraception (hormonal or barrier method of birth control; abstinence) prior to study
entry, for the duration of study treatment, and for 6 months after completion of M3814
and avelumab administration. Should a woman become pregnant or suspect she is pregnant
while she or her partner is participating in this study, she should inform her
treating physician immediately. Because there is an unknown but potential risk for
adverse events in nursing infants secondary to treatment of the mother with M3814 and
avelumab, breastfeeding should be discontinued if the mother is treated with M3814 and
avelumab
- Ability to understand and the willingness to sign a written informed consent document.
Participants with impaired decision-making capacity (IDMC) who have a close caregiver
or legally authorized representative (LAR) and/or family member available will also be
eligible

within two years, or may interfere with the interpretation of the efficacy and safety
outcomes of this study in the opinion of the treating investigator. Superficial
bladder cancer, nonmelanoma skin cancers, and low-grade prostate cancer not requiring
cytotoxic therapy should not exclude participation in this trial. Patients with
chronic lymphocytic leukemia (CLL) may be enrolled if they do not require active
chemotherapy and their hematologic, renal and hepatic function meets criteria
previously mentioned
- Patients with psychiatric illness/social situations that would limit compliance with
study requirements
- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to M3814 or avelumab
- Patients unable to discontinue medications or substances that are potent inhibitors,
inducers or sensitive substrates of CYP3A4/5 or CYP2C19 prior to starting M3814 and
avelumab are ineligible. Medications or substances that are strong inhibitors of
CYP3A4/5 or CYP2C19 must be discontinued at least 1 week prior to first M3814 dose.
Strong inducers of CYP3A4/5 or CYP2C19 must be stopped at least 3 weeks prior to the
first dose. Drugs mainly metabolized by CYP3A with a narrow therapeutic index as
judged by the investigator must stop at least 1 day prior to first M3814 dose. Because
the lists of these agents are constantly changing, it is important to regularly
consult a frequently-updated medical reference. As part of the enrollment/informed
consent procedures, the patient will be counseled on the risk of interactions with
other agents, and what to do if new medications need to be prescribed or if the
patient is considering a new over-the-counter medicine or herbal product. The primary
elimination mechanism of avelumab is proteolytic degradation, thus there are no
contraindicated medications with respect to avelumab
- Patients who cannot discontinue concomitant proton-pump inhibitors (PPIs) prior to
starting M3814 and avelumab. These must be discontinued >= 5 days prior to starting
M3814 and avelumab. Patients do not need to discontinue calcium carbonate. H2 blockers
are allowed provided they are taken at least 2 hours after M3814 dose
- Patients receiving sorivudine or any chemically related analogues (such as brivudine)
and not able to discontinue prior to starting M3814 and avelumab are excluded
- Pregnant and lactating women are excluded from this study because M3814 and avelumab
are agents with the potential for teratogenic or abortifacient effects. Because there
is an unknown but potential risk for adverse events in nursing infants secondary to
treatment of the mother with M3814 and avelumab, breastfeeding should be discontinued
if the mother is treated with M3814 and avelumab
- Patients who have received live vaccination within 30 days before starting M3814 and
avelumab
