Oleclumab and Durvalumab for the Treatment of Recurrent, Refractory, or Metastatic Sarcoma

Trial Status: Approved

This phase II trial investigates how well oleclumab and durvalumab work in treating patients with sarcoma that has come back (recurrent) or does not respond to treatment (refractory) or has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as oleclumab and durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Inclusion Criteria

  • Age: 18 years of age or older (cohort 1 and cohort 2); 12 years of age or older (cohort 3)
  • Histologically or cytologically confirmed sarcoma that fall into one of the following categories. Patients with low-grade tumors are eligible if there is definite evidence of metastasis or progression * Angiosarcoma * Dedifferentiated liposarcoma * Osteosarcoma
  • Must have received and have progressed, are refractory or intolerant to standard therapy appropriate for the specific sarcoma subtype, if there is a standard therapy for the subtype
  • Subjects must have at least 1 lesion that is measurable by RECIST * A previously irradiated lesion can be considered a target lesion if the lesion is well defined, measurable per RECIST, and has clearly progressed since radiation * Subjects undergoing fresh tumor biopsies must have additional non-target lesions that can be biopsied at acceptable risk as judged by the investigator or if no other lesions suitable for biopsy, then a RECIST target lesion used for biopsy must be >= 2 cm in longest diameter
  • Subjected must consent to provide archived tumor specimens for correlative biomarker studies. Tumor tissue must be identified and availability confirmed prior to initiation of study therapy. In the setting where archival material is unavailable or unsuitable for use, or there have been multiple intervening therapies subjects must consent and undergo fresh tumor biopsy. A tumor lesion planned for biopsy must not have a RECIST target lesion unless there are no other lesions suitable for biopsy and lesions used for biopsy is >= 2 cm in longest diameter
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 (use Karnofsky for patients > 16 years and Lansky for patients =< 16)
  • Absolute neutrophil count >= 1.5 x 10^9/L (1,500/mm^3) (without growth factor within 28 days of first dose or transfusion within 14 days of first dose support)
  • Platelet count >= 100 x 10^9/L (100,000/mm^3) (without growth factor within 28 days of first dose or transfusion within 14 days of first dose support)
  • Hemoglobin >= 9.0 g/dL (without growth factor within 28 days of first dose or transfusion within 14 days of first dose support)
  • Calculated creatinine clearance (CrCl) or 24-hour urine CrCl > 40 mL/min Cockcroft-Gault formula (using actual body weight) will be used to calculate CrCl
  • Total bilirubin =< 1.5 x upper limit of normal (ULN); for subjects with documented/suspected Gilbert's disease or liver metastases, bilirubin =< 3 x ULN
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x ULN; for subjects with hepatic metastases, ALT and AST =< 5 x ULN
  • Female patients of childbearing potential who are not abstinent and intend to be sexually active with a non-sterilized male partner must use at least 1 highly effective method of contraception (defined below) from the time of screening throughout the total duration of the drug treatment and the drug washout period (90 days after the last dose of durvalumab monotherapy). Non-sterilized male partners of a female patient of childbearing potential must use male condom plus spermicide throughout this period. Cessation of birth control after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Female patients should also refrain from breastfeeding throughout this period.
  • Non-sterilized male patients who are not abstinent and intend to be sexually active with a female partner of childbearing potential must use a male condom plus spermicide from the time of screening throughout the total duration of the drug treatment and drug washout period (90 days after the last dose of durvalumab monotherapy). However, periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Male patients should refrain from sperm donation throughout this period
  • Female partners (of childbearing potential) of male patients must also use a highly effective method of contraception throughout this period as defined below. Notes: Females of childbearing potential are defined as those who are not surgically sterile (i.e., bilateral salpingectomy, bilateral oophorectomy, or complete hysterectomy) or post-menopausal. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: * Women < 50 years of age would be considered post-menopausal if they have amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution. * Women >= 50 years of age would be considered post-menopausal if they have amenorrheic for 12 months or more following cessation of all exogenous hormonal treatment, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago. Highly effective methods of contraception, defined as one that results in a low failure rate (i.e., less than 1% per year) when used consistently and correctly are described below. Note that some contraception methods are not considered highly effective (e.g. male or female condom with or without spermicide; female cap, diaphragm, or sponge with or without spermicide; non-copper containing intrauterine device; progesterone-only oral hormonal contraceptive pills where inhibition of ovulation is not the primary mode of action [excluding Cerazette/desogestrel which is considered highly effective]; and triphasic combined oral contraceptive pills. * Copper T intrauterine device * Levonorgestrel-releasing intrauterine system: e.g., Mirena * Implants: Etonogestrel-releasing implants: e.g. Implanon or Norplant * Injection: Medroxyprogesterone injection: e.g., Depo-Provera * Combined pill: Normal and low dose combined oral contraceptive pill * Patch: Norelgestromin/ethinylestradiol-releasing transdermal system: e.g., Ortho Evra * Minipill: Progesterone based oral contraceptive pill using desogestrel: Cerazette is currently the only highly effective progesterone-based

PRIMARY OBJECTIVES:

I. To estimate the tumor response (Response Evaluation Criteria in Solid Tumors [RECIST]) at 4 months in patients with relapsed/refractory sarcoma. (Cohorts 1 and 2)

II. To determine the event-free survival (EFS) rate at 4 months after initiation of the treatment in patients with relapsed/refractory osteosarcoma receiving novel immunotherapeutic agents. (Cohort 3)

SECONDARY OBJECTIVES:

I. To determine the progression-free survival (PFS) rate at 12 weeks after initiation of the treatment in patients with relapsed/refractory sarcoma receiving novel immunotherapeutic agents.

II. To estimate the tumor response (Immune-related Response Criteria [irRC] and RECIST) in patients with relapsed/refractory sarcoma.

III. To evaluate the safety and tolerability of receiving novel immunotherapeutic agents in patients with relapsed/refractory sarcoma.

IV. To estimate the median PFS and overall survival (OS) in patients with relapsed/refractory sarcoma receiving novel immunotherapeutic agents.

EXPLORATORY OBJECTIVES:

I. To determine expression of biomarkers (including but not limited to CD73, PD-1 and PD-L1) in pre & post treatment (tx) samples.

II. Quantification and characterization of the immune infiltrate (and other histologic and immunohistologic changes) from tissue samples prior to treatment initiation and post treatment (biopsy at week 6).

III. Identification/quantification of immunologic changes (CD4+, CD8+, Teff, Treg cells and NK cells) in peripheral blood.

IV. Determining an immunoscore based on baseline tumor sample (identification of molecular response/resistance patterns/future therapy options).

OUTLINE:

Patients receive oleclumab intravenously (IV) over 1 hour every 2 weeks for 5 doses, then every 4 weeks thereafter. Patients also receive durvalumab IV over 1 hour every 4 weeks. Cycle repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, and then every 3 months for up to 5 years.
