| Eligibility |
Inclusion Criteria:
- Subjects must have histologically confirmed malignancy that is metastatic or
unresectable and for which standard curative measures do not exist or are no longer
effective
- Subjects will be eligible for this study based on the presence of actionable
aberrations in one or more of the following DNA damage response (DDR) genes: ARID1A,
ATM, ATR, ATRX, BAP1, BARD1, BRCA1/2, BRIP1, CDK12, CHEK2, FANCA, FANCC, FANCD2,
FANCE, FANCF, FANCM, MRE11A, MSH2, NBN (NBS1), PALB2, RAD51, RAD51C, RAD51D, SMARCB1,

consultation with the MD Anderson Cancer Center Institute for Personalized Cancer
Therapy Precision Oncology Decision Support (PODS) group. Variant interpretation for
actionability will be performed by PODS
- Subjects with germline defects in DDR genes are eligible for this trial
- The collection of archival tumor tissue (within 1 year prior to study enrollment) will
be mandatory. Tumor biopsies on cycle 1 day 15 will be mandatory. Subjects will not be
put at undue risk to obtain the biopsy at cycle 1 day 15 (C1D15). A biopsy at C1D15
will not be required if it poses a serious/severe complication risk greater than 2%.
All other biopsy time points are not mandatory but will be strongly encouraged where
feasible. These include at baseline and at disease progression. Archival and fresh
tissue requests can be waived in exceptional circumstances with principal investigator
(PI) approval and only where rationale is documented
- Subjects must have received at least 1 line of systemic therapy in the
advanced/metastatic setting. Subjects with diseases without known effective options,
and subjects who had declined standard of care therapy prior to study introduction are
also eligible
- Subjects enrolling in the dose escalation should have progressed on or be intolerant
to all therapies known to confer a clinical benefit. Subjects must not have refused
all available therapies

institutional ULN or =< 5 X institutional ULN in the presence of liver metastases
- Serum creatinine =< 2 X ULN or estimated creatinine clearance >= 30 mL/min according
to the Cockcroft-Gault formula
- Female patients of childbearing potential must have a negative serum or urine
pregnancy test at screening (and again at baseline just prior to first administration
of study drugs)
- Female patients of non-childbearing potential must meet at least 1 of the following
criteria:
- Achieved postmenopausal status, defined as follows: cessation of regular menses
for at least 12 consecutive months, with no alternative pathological or
physiological cause;
- Have undergone a documented hysterectomy and/or bilateral oophorectomy
- Have medically confirmed ovarian failure All other female patients (including
female patients with tubal ligation) are considered to be of childbearing
potential
- Women of childbearing potential and fertile men must agree to use adequate
contraception when sexually active from signing of the informed consent form for the
full study until at least 6 months after the last study drug administration. Patients
must agree to utilize 2 reliable and acceptable methods of contraception
simultaneously. A man is considered fertile after puberty unless permanently sterile
by bilateral orchiectomy. Men taking part in this study are advised not to father a
child during and up to 6 months after treatment; prior to treatment, advice should be
sought for conserving sperm due to the chance of irreversible infertility as a
consequence of treatment. Female partners of childbearing potential from male study
patients have to use adequate contraception / birth control between signing of the
informed consent and 6 months after the last administration of the study drug if the
male study patient is not sterilized. The investigator or a designated associate is
requested to advise the patient how to achieve highly effective birth control. Highly
effective (failure rate of less than 1% per year) contraception methods, when used
consistently and correctly, include:
- Combined (estrogen and progestin containing: oral, intravaginal, transdermal) and
progestin-only (oral, injectable, implantable) hormonal contraception associated
with inhibition of ovulation
- Intra-uterine device or intrauterine hormone-releasing system
- Bilateral tubal occlusion or vasectomized partner (provided that partner is the
sole sexual partner and has received medical assessment of the surgical success)
- Sexual abstinence (reliability to be evaluated in relation to the duration of the
clinical trial and the preferred and usual lifestyle of the patient) Male
patients with a female partner of reproductive potential must use a condom and
ensure that an additional form of contraception is also used during treatment and
until 6 months after last study drug administration. Patients must agree to
utilize 2 reliable and acceptable methods of contraception simultaneously

the patient has been informed of all pertinent aspects of the study
- Willing and able to comply with scheduled visits, treatment plan, laboratory tests,
and other procedures

undetectable viral loads within the past 6 months on this same regimen; the most
recent undetectable viral load must be within the past 12 weeks
- They must have a CD4 count >= 250 cells/mcL over the past 6 months on this same
anti-retroviral regimen and must not have had a CD4 count < 200 cells/ mcL over
the past 2 years, unless it was deemed related to the cancer and/or
chemotherapy-induced bone marrow suppression
- For patients who have received chemotherapy in the past 6 months, a CD4
count < 250 cells/mcL during chemotherapy is permitted as long as viral
loads were undetectable during this same chemotherapy

recent (within the past year) or active suicidal ideation or behavior or laboratory
abnormality that may increase the risk associated with study participation or
investigational product administration or may interfere with the interpretation of
study results, and in the judgement of the Investigator, would make the patient
inappropriate for entry into this study
- Pregnant female patients, breastfeeding female patients, fertile male patients, and
female patients of childbearing potential who are unwilling or unable to use 2 highly
effective methods of contraception as outlined in this protocol for the duration of
the study, and for at least 6 months after the last dose of study drug administration
