Background: EP0057 consists of a sugar molecule cyclodextrin linked to a chemotherapy drug called camptothecin. The combined molecule or "nanoparticle drug conjugate" travels through the blood. Once inside cancer cells, the chemotherapy drug is released from the molecule. Olaparib is a drug that may stop cancer cells from repairing the DNA damage caused by chemotherapy. Researchers want to see how safe it is to give EP0057 and olaparib together and to see how well the combination treats a specific type of lung cancer called small cell lung cancer (SCLC).

Objectives:

To test the safety and maximum dose of EP0057 and olaparib together. To test how well they treat small cell lung cancer.

Eligibility:

Adults 18 and older with small cell lung cancer.

Design:

Participants will be screened with standard cancer care tests.

Participants will get the 2 study drugs in 28-day cycles. EP0057 will be given every 2 weeks, through a small plastic tube in an arm vein. Olaparib will be taken by mouth twice a day most days. Participants will keep a pill diary.

For Cycle 1, participants will have 3 visits. All other cycles will have 2 visits.

At study visits, participants may have:

-Blood and hair samples taken

-History and Physical exam

-Questions about health and side effects

-Pregnancy test

-Optional tumor biopsy where a piece of tumor is removed by needle after numbing the skin.

-CT scan

-Injection of EP0057 (twice per cycle)

-Olaparib prescription <TAB>

Participants will have a follow-up visit 4 weeks after finish taking the drugs. They will have a physical exam and blood tests. They may have a tumor biopsy. The study team will call the patient every 3 months for follow up after completing the study treatment.

Eligibility

INCLUSION CRITERIA: - Phase I

-Patients must have histologically or cytologically confirmed advanced solid tumor that is resistant or refractory to standard therapy.

-A minimum of 2 weeks will be required from any prior therapy, including chemotherapy, immunotherapy and/or radiation. In addition, recovery to Grade <= 1 from all reversible toxicities related to prior therapy is required at study entry.

-Patients do not need to have measurable disease to enroll on phase I.

-Age 18 years.

-ECOG performance status <=2

-Patients with treated brain metastases (surgery, whole or stereotactic brain radiation) are allowed provided the lesions have been stable for at least 2 weeks and the patient is off steroids or is on a stable dose of steroids. Patients with brain metastases should not require use of enzyme-inducing antiepileptic drugs (e.g., carbamazepine, phenytoin, or phenobarbital) within 14 days before first dose and during study. Use of newer antiepileptics that do not produce enzyme induction drug-drug interactions (DDIs) is allowed.

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

--leukocytes >=3,000/mcL

--absolute neutrophil count >=1,500/mcL without growth factor support

--platelets >=100,000/mcL without growth factor support

--hemoglobin >=9 g/dL, and no blood transfusion within 4 weeks.

OR

--Hemoglobin >10 g/dL, and no blood transfusion within 2 weeks.

--creatinine <= ULN

OR

--creatinine clearance >= 51 mL/min (calculated using the Cockroft-Gault formula) for patients with creatinine levels above institutional normal.

-The effects of EP0057 and olaparib on the developing human fetus are unknown. For this reason and because these agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and for 120 days (both male and female) following last dose of study drug. 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. Fertile females of childbearing potential are defined as women physically capable of becoming pregnant unless the female patient cannot have children because of surgery or other medical reasons (effective tubal ligation, ovaries or the uterus removed, or are post-menopausal). Post-menopausal is defined as:

--Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments,

--LH and FSH levels in the post-menopausal range for women under 50,

--radiation-induced oophorectomy with last menses >1 year ago,

--chemotherapy-induced menopause with >1 year interval since last menses,

--or surgical sterilization (bilateral oophorectomy or hysterectomy).

-The effects of EP0057 and olaparib on the developing human fetus are unknown. For this reason and because these agents are known to be teratogenic, women of child-bearing potential and men must agree to use highly effective contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and for 120 days (both male and female) following last dose of study drug. 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. Fertile females of childbearing potential are defined as women physically capable of becoming pregnant unless the female patient cannot have children because of surgery or other medical reasons (effective tubal ligation, ovaries or the uterus removed, or are post-menopausal).

EXCLUSION CRITERIA: - Phase I and II SCLC and UC Expansion Cohort (note: accrual to the UC cohort ended with amendment version 08/17/2022)

-Patients who are receiving any other investigational agents.

-Persistent toxicities (>= CTCAE grade 2) with the exception of alopecia and neuropathy, caused by previous cancer therapy

-Patients who have had prior treatment with olaparib or other camptothecin inhibitors (UC expansion Cohort Only).

-Patients with myelodysplastic syndrome/acute myeloid leukemia or active pneumonitis; or baseline features suggestive of myelodysplastic syndrome or acute myelogenous leukemia on peripheral blood smear or bone marrow biopsy, if clinically indicated.

-Hypersensitivity to study therapies and its excipients

-Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication.

-History of allergic reactions attributed to compounds of similar chemical or biologic composition to EP0057 and/or olaparib or other agents used in study.

-Patients receiving any medications or substances that are strong and moderate inhibitors or inducers of CYP3A are ineligible.

-Pregnant women are excluded from this study because EP0057 and/or olaparib 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 EP0057 and/or olaparib, breastfeeding should be discontinued if the mother is treated with EP0057 and/or olaparib. These potential risks may also apply to other agents used in this study.

-HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with EP0057 and/or olaparib. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.

-Prolongation of QT/QTc interval (QTc interval >500 msec) using the Fredericia method of QTc analysis or family history of long QT syndrome. If single reading is above these minimum ranges, then repeat test in triplicate and evaluate eligibility based on average value

-Any chronic or concurrent acute liver disease.

-History of stroke, transient ischemic attack (TIA), or myocardial infarction, within 6 months prior to C1D1

-Uncontrolled concurrent disease or illness including but not limited to:

--symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmia

--unstable or untreated cardiac conditions or ejection fraction of <50% as determined by

--echocardiogram (ECHO) or multiple gated acquisition scan (MUGA)

--uncontrolled diabetes mellitus

--psychiatric illness that would limit compliance with study requirements, as determined by the Investigator

-Other severe, acute, or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration or that may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for the study.

EXCLUSION CRITERIA: - mCRPC Expansion Cohort (accrual to the mCRPC cohort ended with amendment version 7/27/2021)

-Patients who have had prior treatment with olaparib or other camptothecin inhibitors.

-The patient has received chemotherapy, radiotherapy, biologic agents or enzalutamide within 3 weeks before the first dose of study treatment (nitrosoureas or mitomycin within 6 weeks). However, for patients receiving abiraterone, they must discontinue the medication at least 14 days before the first dose of study treatment.

-The patient has received any other type of investigational agent within 28 days before the first dose of study treatment.

-The patient has received radionuclide treatment within 6 weeks prior to the first dose of the study treatment

-Patients with evidence of CNS metastasis or leptomeningeal disease within 1 year prior to enrollment will be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Patients with a remote history of brain metastases may be considered if they received sterilizing therapy to the CNS (resection or radiation) and have been CNS progression-free for the 1-year period. Baseline imaging to rule out brain metastases is not required for screening, but should be performed prior to study enrollment if clinically indicated.

-Patients receiving any medications or substances that are strong and moderate inhibitors or inducers of CYP3A are ineligible.

-The patient has not recovered to baseline or CTCAE <= Grade 1 from toxicity due to all prior therapies, including surgery, except alopecia and other non-clinically significant AEs.

-Uncontrolled concurrent disease or illness including but not limited to:

--symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmia

--unstable or untreated cardiac conditions or ejection fraction of <50% as determined by echocardiogram (ECHO) or multiple gated acquisition scan (MUGA)

--uncontrolled diabetes mellitus

--psychiatric illness that would limit compliance with study requirements, as determined by the Investigator

-Any of the following within 6 months before the first dose of study treatment:

--unstable angina pectoris

--stroke (including TIA, or other ischemic event)

--myocardial infarction

-Other clinically significant disorders such as:

--active infection requiring intravenous treatment within 7 days of starting protocol treatment

-serious non-healing wound/ulcer/bone fracture (excluding stable compression fracture) within 28 days before the first dose of study treatment

-HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with the study agent.

HBV-or HCV-positive patients are ineligible

-Prolongation of QT/QTc interval (QTc interval >500 msec) using the Fredericia method of QTc analysis or family history of long QT syndrome. If single reading is above these minimum ranges, then repeat test in triplicate and evaluate eligibility based on average value
