NCT05075603

Brief Summary

This is a multicenter Phase 1b study evaluating the safety, tolerability, and preliminary anti-tumor activity of NT-I7 administration following standard of care CD19 chimeric antigen receptor T-cell (CAR T-cell) therapy for eligible subjects with relapsed/refractory (r/r) large B-cell lymphoma (LBCL).

Outcome Measures

Primary Outcomes (3)

  • Incidence, Nature, and Severity of Adverse Events, Graded According to NCI CTCAE v5.0, Except for Cytokine Release Syndrome (CRS) and Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS), Which Were Graded Based on ASTCT Guidelines

    Treatment-Emergent Adverse Event (TEAE) is defined as an Adverse Event (AE) with an onset date on or after NT-I7 administration and on or before Day 100. A serious TEAE is defined as any AE that resulted in any of the following outcomes: death; a life-threatening AE; an AE that resulted in inpatient hospitalization or prolongation of existing hospitalization for ≥24 hours; a persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions; a congenital anomaly/birth defect; important medical events that may not result in death, be life threatening, or require hospitalization may be considered serious when, based upon medical judgment, they may jeopardize the participant and may require medical or surgical intervention to prevent one of the outcomes listed in this definition.

    From NT-I7 administration (Day 21) to Day 100

  • Incidence and Nature of DLTs

    A Dose-Limiting Toxicity (DLT) is defined as any TEAE occurring within the first 21 days after NT-I7 administration that is considered to be at least possibly, probably, or definitely related to NT-I7 per the investigator, and that meets at least one of the protocol-defined non-hematologic or hematologic criteria.

    From NT-I7 administration (Day 21) to Day 42

  • Potential Correlation of Dose Levels With Safety and Efficacy Parameters

    The Recommended Phase 2 Dose (RP2D) was determined based on cumulative safety data and efficacy parameters (Objective Response Rate \[ORR\] and response rate at 6 months).

    Up to 24 months

Secondary Outcomes (4)

  • Measurement of Duration of Response (DoR)

    Up to 24 months

  • Measurement of Progression-Free Survival (PFS)

    Up to 24 months

  • Measurement of Overall Survival (OS)

    Up to 24 months

  • Rates of Grade 3 and Higher Cytokine Release Syndrome (CRS) or Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS)

    From NT-I7 administration (Day 21) to Day 100

Study Arms (1)

NT-I7 after CAR-T (Kymriah, Yescarta, or Breyanzi) infusion

EXPERIMENTAL

CAR-T infusion administered per standard of care at Day 0 followed by NT-I7 on Day 21.

Drug: Efineptakin alfaDrug: TisagenlecleucelDrug: Axicabtagene ciloleucelDrug: Lisocabtagene Maraleucel

Interventions

NT-I7 is administered via an intramuscular injection after CAR-T infusion on Day 21.

Eligibility Criteria

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

You may not qualify if:

  • Subjects meeting any of the following criteria are not eligible for enrollment in the study:
  • In Dose Escalation phase: Grade ≥3 cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS) post-CD19 CAR T-cell infusion. Note: Grade 1 or 2 CRS or ICANs must be completely resolved \>3 days prior to NT-I7 injection
  • In Dose Expansion phase: Grade ≥3 CRS or ICANS post-CD19 CAR T-cell infusion. Note: Grade 1 or 2 CRS or ICANS must be completely resolved \>3 days prior to NT-I7 injection
  • Pregnant, lactating or breastfeeding or expecting to conceive or father children within the study duration from screening through 120 days after the last dose of study treatment.
  • Subjects with documented current central nervous system (CNS) involvement by lymphoma are to be excluded from study participation.
  • Any concurrent chemotherapy or biologic or hormonal therapy for cancer treatment.
  • Note: Concurrent use of hormones for noncancer-related conditions (e.g., insulin for diabetes and hormone replacement therapy) is acceptable. In addition, local treatment (e.g., by local surgery or radiotherapy) of isolated lesions for palliative intent is acceptable beyond the dose-limiting toxicity (DLT) evaluation period with prior consultation and agreement with the medical monitor.
  • Subjects who have autoimmune disease history for the past 2 years, including but not limited to systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, vascular thrombosis associated with antiphospholipid syndrome, Wegener's granulomatosis, Sjögren's syndrome, Bell's palsy, Guillain-Barre syndrome, multiple sclerosis, vasculitis, or glomerulonephritis. The following are exceptions to this criterion:
  • Subjects with vitiligo or alopecia.
  • Subjects with type 1 diabetes mellitus.
  • Subjects with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement
  • Psoriasis not requiring systemic treatment.
  • Have active and clinically relevant bacterial, fungal, viral, or TB infection, including known Hepatitis A, B, or C or human immunodeficiency virus (HIV) (testing not required).
  • Concurrent enrollment in another clinical study unless it is an observational (noninterventional) clinical study.
  • Receipt of any conventional or investigational anticancer therapy, not otherwise specified above, within 30 days prior to NT-I7 injection.
  • +15 more criteria
