Outcome Measures

Primary Outcomes (1)

  • Maximum Tolerated Dose/MTD of DLL3-SAVVYZ-IL18 CAR T cell

    The objective of the dose-escalation phase is to determine the MTD of this dose-escalation schedule. The MTD will be defined as the dose at which the toxicity rate does not exceed an acceptable threshold of toxicity, assumed at 25% in this study.

    up to 1 year

Study Arms (3)

Dose Level 1

EXPERIMENTAL

This is the starting dose of DLL3-SAVVYZ-IL18 CAR T cell Dose

Drug: DLL3-SAVVYZ-IL18 CAR T cell

Dose Level 2

EXPERIMENTAL

Eligible participants will receive DLL3-SAVVYZ-IL18 CAR T cell Dose at this Dose Level if no Dose Limiting Toxicities are experienced at Dose Level 1

Drug: DLL3-SAVVYZ-IL18 CAR T cell

Dose Level -1

EXPERIMENTAL

Eligible participants will receive DLL3-SAVVYZ-IL18 CAR T cell Dose at this Dose Level if Dose Limiting Toxicities are experienced at Dose Level 1

Drug: DLL3-SAVVYZ-IL18 CAR T cell

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • History of DLL3+ neuroendocrine tumors
  • Includes patients with histologically confirmed SCLC, as well other advanced neuroendocrine tumors (NETs), including large cell neuroendocrine carcinomas (LCNECs), gastroenteropancreatic NETs (GEP-NETs), laryngeal NETs, genitourinary (GU) tract NETs, neuroendocrine prostate cancers (NEPCs), gynecological tract NETs, neuroblastomas, salivary NETs, skin NETs, NETs of unknown primary, or other tumor confirmed positive for DLL3 by IHC
  • Any disease status is eligible for collection.
  • DLL3 expression detected by IHC using archival tumor tissue or tissue obtained from a biopsy performed as part of standard clinical care. No new biopsy will be performed solely for DLL3 IHC eligibility testing.
  • Off any immunosuppressive agents for 14 days prior to collection (physiologic dose of corticosteroids is acceptable)
  • Any participant with histologically confirmed SCLC or DLL3 positive tumor who has had one line of approved systemic therapy for limited or extensive stage disease and has progressed or is no longer deriving benefit or standard treatment is no longer tolerable or declines further standard treatment.
  • Prior treatment should include an approved platinum-based regimen with/without ICI therapy if applicable to their disease.
  • Other advanced tumors are eligible if there is documented progression and/or relapse after appropriate frontline treatment(s) and otherwise meet eligibility criteria.
  • At least 1 measurable lesion as defined per modified RECIST 1.1 within 21 days prior to first dose of LDC.
  • Age \> 18 years old at the time of signing the informed consent.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
  • Minimum life expectancy of 12 weeks.
  • Participants previously treated with DLL3-specific therapies (i.e. antibody-drug conjugates, T-cell engager molecules) are permitted.
  • History of CNS metastatic disease is permitted if previously treated and stable, defined as no evidence of radiographic progression for at least 4 weeks prior to the first dose of LDC, with any neurologic symptoms returned to baseline. Asymptomatic CNS metastatic disease must also be radiographically stable for at least 4 weeks prior to the first dose of LDC.
  • Adequate organ function is required, defined as follows:
  • +7 more criteria

You may not qualify if:

  • Pregnant or lactating female participants; female participants of reproductive potential, unless they agree to use a highly effective method of contraception or abstain from heterosexual intercourse while receiving study treatment and for at least 12 months after all treatment is finished.
  • Sexually active male participants with female partners of reproductive potential, unless they agree to use a condom during intercourse and their female partners use a highly effective method of contraception while the participant is receiving study treatment and for at least 12 months after all treatment is finished.
  • Primary CNS malignancies, including glioblastoma multiforme (GBM), are excluded.
  • Any systemic anti-cancer therapy within 14 days or at least 4 half lives prior to time of T cell collection, whichever is shorter.
  • Radiation therapy completed within 7 days prior to time of T cell collection.
  • Uncontrolled, symptomatic, intercurrent infection
  • Patients with following cardiac conditions will be excluded:
  • New York Heart Association (NYHA) stage III or IV congestive heart failure.
  • Myocardial infarction ≤ 6 months prior to enrollment.
  • Positive serologic test results for HIV.
  • Patients with active hepatitis B infection (as manifested by either detectable hepatitis B virus DNA by PCR and/or positivity for hepatitis B surface antigen)
  • Patients with active hepatitis C infection (as manifested by detectable hepatitis C virus RNA by PCR)
  • For prior immune related adverse events (irAEs):
  • Unresolved pneumonitis of any grade or history of any grade ICI-mediated CNS toxicities
  • Other unresolved toxicity grade 2 or higher, excluding hypothyroidism.
  • +9 more criteria
