About this study

Official title: Phase I Study of Reirradiation With NBTXR3 for Inoperable Locoregional Recurrent Non-Small Cell Lung Cancer (NSCLC)

This phase I trial investigates the best dose and side effects of NBTXR3 when given together with radiation therapy for the treatment of non-small cell lung cancer that cannot be treated by surgery (inoperable) and has come back (recurrent). NBTXR3 is a radio-enhancer designed to increase the radiotherapy energy dose deposition inside tumor cells. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving NBTXR3 and radiation therapy may increase radiation-dependent tumor cell killing without increasing the radiation exposure of healthy surrounding tissues.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To assess the safety of 45 Gy in 15 fractions in patients with inoperable, locoregional recurrent NSCLC, previously treated with definitive radiation therapy.

II. To determine the recommended phase II dose (RP2D) of NBTXR3 activated by radiotherapy in patients with inoperable, locoregional recurrent NSCLC, previously treated with definitive radiation therapy.

SECONDARY OBJECTIVES:

  1. To evaluate the safety and feasibility of reirradiation with NBTXR3 in patients with inoperable, locoregionally recurrent NSCLC.

II. To evaluate the anti-tumor response of reirradiation with NBTXR3 in patients with inoperable, locoregionally recurrent NSCLC.

III. To evaluate time-to-event outcomes after reirradiation with NBTXR3 in patients with inoperable, locoregionally recurrent NSCLC

EXPLORATORY OBJECTIVE:

  1. To assess biomarkers of response in patients treated with NBTXR3/radiation therapy (RT).

OUTLINE: This is a dose-escalation and dose-expansion study of NBTXR3.

Patients receive NBTXR3 intratumorally (IT) or intranodally on day 1. Within 15 days, patients undergo RT 5 times weekly (Monday-Friday) over 3 weeks for a total of 10-15 fractions.

After completion of study treatment, patients are followed up every 3 months for 2 years, then every 6 months for up to 5 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of dose limiting toxicity (DLT) Cohort 1

    Defined as the occurrence and frequency of DLTs by dose level of NBTXR3. Descriptive summary tables will be produced, providing the DLTs by initial planned dose level of NBTXR3, initial planned volume of NBTXR3 to be injected, the injected volume and the RT dose given.

    Measured: Day 1 to 3 months post radiation therapy (RT)

  2. Determination of the Recommended Phase II Dose (RP2D)

    Will be selected based on isotonic regression. Specifically, the recommended phase II dose (RP2D) will be determined as the dose for which the isotonic estimate of the toxicity rate is closest to the target toxicity rate (30%).

    Measured: 4 weeks post RT

  3. Incidence of dose limiting toxicity (DLT) Cohort 2

    Defined as the occurrence and frequency of DLTs by dose level of hafnium oxide-containing nanoparticles NBTXR3 (NBTXR3). Descriptive summary tables will be produced, providing the DLTs by initial planned dose level of NBTXR3, initial planned volume of NBTXR3 to be injected, the injected volume and the RT dose given. Incidence of dose-limiting toxicities (DLTs) for NBTXR3 with RT. The DLT window for cohort 2 (NBTXR3 + RT) is from Day 1 to 4 weeks post RT.

    Measured: Day 1 to 4 weeks post RT

  4. Determination of the maximum tolerated dose (MTD)

    Determination of the MTD will be selected based on isotonic regression. Specifically, the MTD will be determined as the dose for which the isotonic estimate of the toxicity rate is closest to the target toxicity rate (30%).

    Measured: 4 weeks post RT

Secondary outcomes (9)

  1. Incidence of NBTXR3/RT related late onset toxicities

    Defined as any grade >= 3 adverse events (AE) occurring after the end of treatment visit and until end of study (EoS). All AEs will be coded and graded according to National Cancer Institute-Common Terminology Criteria for Adverse Events version (v)5 criteria.

    Measured: Up to 5 years

  2. Feasibility of NBTXR3 injection in lung

    Feasibility is defined as the ability to do intratumoral and/or intranodal lung injection of NBTXR3.

    Measured: Up to 5 years

  3. Feasibility of the regional lymph nodes

    Feasibility is defined as the ability to do intratumoral and/or intranodal lung injection of NBTXR3.

    Measured: Up to 5 years

  4. Objective response rate (ORR)

    Defined as the proportion of participants with either a complete response (CR) or a partial response (PR) (ORR=CR + PR) or stable disease (SD) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 and immune-related (ir)RECIST in the target lesion(s) and overall.

    Measured: Up to 5 years

  5. Local disease control rate (LDCR)

    Defined as the proportion of patients who demonstrate a radiographic response to treatment (RECIST v1.1 and irRECIST). The response to treatment should be a CR, PR and/or SD within the selected target lesion(s). Will be estimated by the Kaplan-Meier method. Median times and 95% confidence intervals will also be estimated.

    Measured: At 1 and 2 years

  6. Local progression free survival (LPFS)

    Will be estimated by the Kaplan-Meier method. Median times and 95% confidence intervals will also be estimated.

    Measured: From NBTXR3 injection to local (i.e., within the lungs or regional nodes) disease recurrence, local progression, or death from any cause, assessed up to 5 years

  7. Distant progression free survival (DPFS)

    Will be estimated by the Kaplan-Meier method. Median times and 95% confidence intervals will also be estimated.

    Measured: From NBTXR3 injection to the radiographic confirmation (RECIST v1.1 and irRECIST) of a new lesion outside the lungs and regional nodes or death from any cause, assessed up to 5 years

  8. Progression free survival (PFS)

    Will be estimated by the Kaplan-Meier method. Median times and 95% confidence intervals will also be estimated.

    Measured: From NBTXR3 injection to local or recurrence, local progression, distant progression, confirmed radiographically (RECIST v1.1 and irRECIST), or death from any cause, assessed up to 5 years
