A Study of Etrumadenant and Zimberelimab in People With Dedifferentiated Liposarcoma
Study Details
Study Description
Brief Summary
Participants will have a diagnosis of dedifferentiated liposarcoma (DDLS) that has spread beyond its original location (advanced). In addition, their DDLS either has come back after treatment (recurrent), has spread to different parts of your body (metastatic), or is unable to be removed surgically (unresectable). The purpose of this study is to find out whether the combination of etrumadenant and zimberelimab is an effective treatment for people with advanced DDLS.

-
International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 X ULN unless patient is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
-

Contraception Requirements
Female participants of reproductive potential and male participants with female partners of reproductive potential are required to use highly effective contraceptive measures from the first dose of study treatment until 30 days after the last dose of etrumadenant or 90 days after the last dose of zimberelimab, whichever is longer.
-
A female participant (or female partner of a male participant) is considered fertile following menarche and until becoming post-menopausal unless permanently sterile.
-
Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy.
-
A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle-stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient.
-
A man is considered fertile after puberty unless permanently sterile by bilateral orchidectomy
Highly effective contraception is defined as use of one or more methods that result in a low failure rate (i.e., less than 1%). Highly effective contraceptive measures include:
-
Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal, transdermal
-
Progestogen only hormonal contraception associated with inhibition of ovulation: oral, injectable, implantable
-
Intrauterine device
-
Intrauterine hormone-releasing system in combination with a barrier method (preferably male condom)
-
Surgical sterilization
-
Female participant or female partner of the male participant has undergone bilateral tubal ligation
-
Male participant is vasectomized (with documented medical confirmation of surgical success) and is the sole sexual partner of a female with reproductive potential
-
Complete sexual abstinence defined as refraining from heterosexual intercourse during the entire period of risk associated with study treatment. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the participant
To ensure proper birth control, female participants who use hormonal contraception should use an efficient barrier contraceptive (condom plus spermicide). Additionally, male participants, when having sexual intercourse with a female of reproductive potential, should use an efficient barrier contraceptive (condom plus spermicide); the respective partner should also use an additional efficient contraceptive method (e.g., oral pills, intrauterine device, or diaphragm, and spermicide).
Exclusion Criteria:
Patients who fulfil any of the following criteria are not eligible for admission to the study:
-
Prior treatment with systemic PD-1 or PD-L1 inhibitor
-

-
Primary immunodeficiency state such as Severe Combined Immunodeficiency Disease
-
Concurrent opportunistic infection
-
Receiving systemic immunosuppressive therapy (> 2 weeks) including oral steroid doses > 10 mg/day of prednisone or equivalent within 14 days prior to enrollment. However, in the setting of non-immune mediated indications for use, chronic/active low dose steroid use may be permitted at the discretion of the principal investigator.

-
Chronic carriers of HBV infection (HBsAg-positive, undetectable or low HBV DNA, and normal ALT) or individuals who have serologic evidence of a resolved prior HBV infection (i.e., HBsAg-negative and anti-HBc-positive) may be eligible if suppressive antiviral therapy can be safely administered.
-
Patients who have completed curative antiviral treatment for HCV and have a viral load below the limit of quantification will be eligible (e.g. a patient who is HCV Ab positive but HCV RNA negative due to prior treatment or natural resolution)
-
Has a known history of active tuberculosis infection
