Background:

Carcinoma is a type of cancer that starts in cells that make up the skin or the tissue that lines organs and glands. These include cancers of the ovaries (ovarian carcinoma); the lining of the womb (endometrial adenocarcinoma); and the bladder (urothelial carcinoma). These cancers often return after the first round of treatment, and survival rates are very low. Better treatments are needed.

Objectives:

To test a study drug (ACR-368), used alone or combined with an approved drug (low dose gemcitabine, or LDG).

Eligibility:

People aged 18 years and older who have ovarian, endometrial, or urothelial cancer.

Design:

Participants will be screened. They will have a physical exam and a test of heart function. They will give blood and urine samples. They will have an imaging scan. They will have a biopsy (tissue sample) of their tumor.

Participants will be assigned to 1 of 2 groups.

ACR-368 is administered intravenously, that is, through a tube attached to a needle inserted into a vein in the arm. Each treatment takes about 60 minutes. The drug will be given once every 14 days to all participants.

Participants in the second group will also receive LDG. LDG is also administered intravenously, over about 60 minutes. Every 14 days, these participants will receive the LDG first; then, after a 3-hour wait, they will receive the ACR-368.

Imaging scans, blood sampling, and other tests may also be done during treatment visits.

Participants may remain in the study as long as they are benefiting from treatment.

-Subject must have at least 1 measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria (by local Investigator). Subject must have radiographic evidence of disease progression based on RECIST criteria following the most recent line of treatment. Biochemical recurrence (eg, CA-125 in ovarian carcinoma) only is not considered as disease progression.

-Subject must be willing to provide tissue from a newly obtained tumor biopsy from an accessible tumor lesion not previously irradiated. Newly obtained is defined as a specimen obtained up to 12 weeks prior to initiation of treatment on Day 1 if no intercurrent systemic therapy in the interval. For biopsies obtained prior to the signing of the consent, Investigators should contact the Medical Monitor to confirm sample will be acceptable.

-Subject must be willing to provide an archival tumor tissue block or at least 20 unstained slides, if available.

-Subject must have stabilized or recovered (Grade 1 or baseline) from all prior therapy-related toxicities, except as follows:

--Alopecia is accepted.

-Subject must have adequate coagulation profile as defined below if not on anticoagulation. If subject is receiving anticoagulation therapy, then subject must be on a stable dose of anticoagulant for >= 1 month:

--Prothrombin time within the ULN, and

--Activated partial thromboplastin time within the ULN.

-Female subjects must be non-lactating.

-Women of childbearing potential must agree to use a highly effective contraceptive method while on ACR-368 and for at least 3 months after the last dose. Males who have either a female partner of childbearing potential or a pregnant female partner must be sterile (biologically or surgically) or use a highly effective method of contraception (any combination of physical and chemical methods) while on ACR-368 and for at least 3 months after the last dose.

-WOCBP must have a negative pregnancy test prior to biopsy (if the biopsy is performed within the Screening window) and within 48 hours prior to dosing of study drug.

TUMOR TYPE-SPECIFIC INCLUSION CRITERIA

Ovarian Carcinoma:

-Subject must have histologically documented, advanced (metastatic and/or unresectable) high-grade serous/endometrioid ovarian, primary peritoneal, or fallopian tube cancer. Platinum-resistant disease, defined as progression or relapse within 6 months after the completion of platinum-based therapy, is eligible. Subjects with platinum sensitive disease (defined as disease which progresses after 6 or more months after the completion of platinum-based therapy) and subjects with primary platinum-refractory disease (defined as progression while on the upfront platinum-based therapy) are not eligible

-Subject must have received at least 1 but no more than 6 prior lines of systemic therapy, including at least 1 line of therapy containing platinum derivative and taxane, and singleagent therapy must be appropriate as the next line of treatment:

--Adjuvant +/- neoadjuvant is considered 1 line of therapy.

--Maintenance therapy (eg, bevacizumab or poly adenosine diphosphate-ribose polymerase [PARP] inhibitors) will be considered part of the preceding line of therapy (ie, not counted independently).

--Therapy changed due to toxicity in the absence of progression will be considered part of the same line (ie, not counted independently).

-Subject must have had prior bevacizumab or did not receive bevacizumab based on Investigator judgment.

-Subjects with or without documented test results assessing alterations in the DNA repair pathway genes, eg, Breast Cancer gene 1 (BRCA1), BRCA2, and homologous recombination deficiency, at Screening are eligible. Patients with known BRCA mutated tumors should have received a PARP inhibitor maintenance or treatment.

-Subject will be enrolled regardless of tumoral folate receptor alpha expression status. Folate receptor alpha expression status will be collected for retrospective analysis, if the information is available.

Endometrial Adenocarcinoma:

-Subject must have histologically documented, high-grade endometrial adenocarcinoma.
