| Eligibility |
Inclusion Criteria:
- Written informed consent obtained prior to any study-specific procedures not
considered part of routine medical care.
- Patients must have histologically confirmed solid tumor that is metastatic or
unresectable, and there is no available therapy likely to convey clinical benefit
- Patients must have measurable disease by RECIST version 1.1. Measurable disease is
defined as at least one dimension (longest diameter to be recorded for non-nodal
lesions and short axis for nodal lesions) as = 20mm (= 2cm) with conventional
techniques or as = 10mm (= 1cm) with spiral computed tomography (CT) scan, MRI, or
calipers by clinical exam. See Section 11 for the evaluation of measurable disease.
- Patients must have recovered to eligibility levels from prior toxicity or adverse
events as a result of previous treatment prior to entering the study (except
alopecia).
- Age =18 years, as no dosing or adverse event data are currently available on the use
of prexasertib in combination with LY3300054 in patients < 18 years of age, children
are excluded from this study.
- ECOG performance status 0-1.
- Patients must have normal organ and marrow function as defined below:
- absolute neutrophil count = 1,500/mcL
- platelets = 100,000/mcL
- total bilirubin = 1.5 × institutional upper limit of normal (ULN)
- AST(SGOT)/ALT(SGPT) = 2.5 × institutional ULN
- creatinine = 1.5 × institutional ULN OR
- creatinine clearance = 60 mL/min by Cockcroft-Gault equation for participants
with creatinine levels above institutional normal.
- Free T4 within institutional normal limits
- The effects of prexasertib and LY3300054 on the developing human fetus are unknown.
For this reason, women of childbearing potential and male patients with partners of
childbearing potential must agree to use two highly effective forms of contraception
(see Section 5.5.1) prior to study entry, for the duration of study participation, and
for 6 months after completion of study. Men treated or enrolled on this protocol must
also agree to use adequate contraception prior to the study, for the duration of study
participation, and for 3 months after completion of prexasertib and LY3300054
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.
- Women of childbearing potential enrolling on study must have a negative serum
pregnancy test prior to registration.
- Childbearing potential is defined as women who are not postmenopausal (defined as
amenorrheic for = 12 months following cessation of any exogenous hormonal treatments;
LH and FSH levels in the postmenopausal range for women under 50; radiation-induced
oophorectomy with last menses > 12 months prior; or chemotherapy-induced menopause
with last menses > 12 months prior) or surgically sterile (bilateral oophorectomy or
hysterectomy).
- Ability to understand and the willingness to sign a written informed consent document.
Patients must be willing and able to comply with the protocol for the duration of the
study including undergoing treatment and scheduled visits and examinations.
Exclusion Criteria:
- Participants who have had chemotherapy, immune therapy, or radiotherapy within 3 weeks
(6 weeks for nitrosoureas or mitomycin C; five-half lives for any investigational or
FDA-approved kinase inhibitors) prior to entering the study. Patients who have
received prior CHK1 inhibitor therapy are excluded. Exposure to prior PD-L1 antibody
will be allowed as long as this was not the most recent treatment prior to enrollment.
- No prior radiation to > 25% of the marrow
- Must not have received more than 4 lines of cytotoxic chemotherapy. A line of therapy
is defined as being preceded by disease progression. Discontinuation of a regimen
without progression (for example, due to toxicity) or a switch of an agent within the
same drug class (for example from cisplatin to carboplatin) will not be considered a
new line of therapy. Similarly, maintenance therapy (continuation maintenance or
switch maintenance) will not be considered a new line of treatment.
- Participants who are receiving any other investigational agents.
- Participants who have undergone major surgery within 14 days of starting the study
treatment, or participants who have not recovered to baseline status from the effects
of major surgery received more than 14 days prior.
- Participants with known brain metastases or carcinomatous meningitis are excluded from
this clinical trial, with the exception of patients with brain metastatic disease that
has previously been treated and remained stable on MRI = 2 months prior to enrollment,
without steroids or anti-epileptic medications. These patients may be enrolled at the
discretion of the Principal Investigator.
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, uncontrolled seizures, myocardial infarction within the past 3 months,
superior vena cava syndrome, unstable spinal cord compression (untreated and unstable
for at least 28 days prior to study entry), or psychiatric illness/social situations
that would limit compliance with study requirements.
- Participants must not have experienced a Grade = 3 immune-related AE or an
immune-related neurologic or ocular AE of any grade while receiving prior
immunotherapy, or experienced a toxicity of any grade that led to permanent
discontinuation of prior immunotherapy as a result of the toxicity. Participants with
prior endocrine adverse events of Grade = 2 are permitted to enroll if stably
maintained on appropriate replacement therapy and are asymptomatic. In the setting of
prior immune-related AE, participants must not have required the use of additional
immunosuppressive agents other than corticosteroids for the management of the adverse
event(s), not have experienced recurrence of the adverse event if re-challenged, and
not currently requiring maintenance doses of > 10 mg of prednisone or equivalent per
day at the time of enrollment.
- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to prexasertib or LY3300054.
- The effects of prexasertib and LY3300054 on the developing human fetus are unknown.
For this reason, pregnant women are excluded from this study. Because there is an
unknown but potential risk for adverse events in nursing infants secondary to
treatment of the mother with prexasertib and LY3300054, breastfeeding women are also
excluded.
- Known HIV-positive participants on combination antiretroviral therapy are ineligible
because of the potential for pharmacokinetic interactions with prexasertib and
LY3300054. In addition, these participants are at increased risk of lethal infections
when treated with marrow-suppressive therapy such as prexasertib.
- Participants with known active or chronic infection with Hepatitis B or C.
- Consistent QTc > 470 msec on more than one screening ECG. Patients with a history of
long QTc syndrome or personal or family history of ventricular arrhythmias will be
excluded
