Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a clinical trial studying intravenous infusions of allogeneic gamma delta T cells after receiving low dose radiotherapy in participants with locally advanced or metastatic non-small cell lung cancer or solid tumors with bone metastases to evaluate the safety and efficacy of combining immunotherapy with radiation therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this clinical trial, or 'study', participants with locally advanced or metastatic, non-small cell cancer (NSCLC) or solid tumors with bone metastases, will receive KB-GDT-01, an allogeneic (cells from healthy donors) gamma delta T-cell product. All participants will receive KB-GDT-01 as intravenous infusions in combination with radiotherapy.

After being informed about the study and its potential risks, during the 28-day screening period, all consented participants will have laboratory tests, assessments, tumor scans, and a tumor biopsy.

Cytokine release syndrome symptoms and other potential adverse effects, will be monitored during the dose limiting toxicity period.

The study will be conducted in 2 parts, with the same number of visits in each part.

In Part 1 Dose Escalation, the study will attempt to identify the best dose with the lowest incidence of adverse effects (AE) and try to identify if the KB-GDT-01 is working (effectiveness). In Part 2 Dose Expansion the best dose will be further investigated for AE and effectiveness. There will be up to 36 participants in Part 1 and up to 21 additional participants in Part 2 of the study.

The total treatment period of the study drug protocol will be completed in 31 days. Participants will then attend clinic visits during a 30-day short-term follow-up period, with a subsequent long-term follow-up period up to 12 months.

Study Design

Allocation Method

NA

Intervention Model

SEQUENTIAL

The maximum tolerated dose (MTD)/recommended Phase 2 dose (RP2D) or the maximum administered dose (MAD) will be determined based on isotonic regression in Part 1 Dose Escalation. If the MTD/MAD shows an acceptable safety and tolerability profile, an additional 12 participants in Part 2 expansion will be enrolled. Three dose levels of KB-GDT-01 will be evaluated and will follow a Bayesian Optimal Interval (BOIN) design rule based on a targeting rate of 25% for dose limiting toxicity (DLT) occurring between the first KB-GDT-01 infusion and Day 40. Depending on observed DLT rate, the safety monitoring committee will assess whether to escalate to the next dose, de-escalate (not applicable for the first dose), hold at current dose or stop the study if at the first dose.

KB-GDT-01 cells

Dose Level 1: 400 x10\^6, 800 x10\^6 or 1600 x10\^6 KB-GDT-01 cells + radiation (1.0 Gy/fraction)

Group Type EXPERIMENTAL

KB-GDT-01

Intervention Type BIOLOGICAL

KB-GDT-01 is an allogeneic, gamma delta T-cell suspension product manufactured from the isolation of healthy donor peripheral blood mononuclear cells (PBMC). The KB-GDT-01 cells are cryopreserved in vapor phase liquid nitrogen (LN2) in 50 mL CryoMACS® cryobags for a total of 200 × 106 viable cells/bag. The KB-GDT-01 cryopreserved product is thawed and administered intravenously (IV) until the entire bag is infused by gravity. Low dose radiotherapy (LDRT) will be administered to selected tumor sites (maximum of 5 isocenters) at 1.0 Gy/fraction on Days 1 and 2, followed by the KB-GDT-01 IV infusion on Day 3. LDRT will be repeated on Days 8 and 9, and the 2nd KB-GDT-01 IV infusion on Day 10.
