Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: Cohort 1: Newly Diagnosed HNSCC who are scheduled to undergo surgical resection

Cohort 1 will undergo 64Cu-DOTA-ECL1i positron emission tomography-computed tomography (PET/CT) once prior to scheduled standard of care (SOC) surgery and prior to any neoadjuvant therapy.

Participants will be followed up via a phone call or in-person visit 24 hours - 14 days after 64Cu-DOTA-ECL1i administration to assess for adverse events. Participants will be followed via medical chart review for standard of care clinical and radiological appointments.

64Cu-DOTA-ECL1i a novel PET imaging tracer that will be provided intravenously (IV) while participants will be positioned supine on the on the scanning table. The injection will be followed with saline flush.

  • 64Cu-d(LGTFLKC)
  • Cu-64 DOTA-ECL1i
Experimental: Cohort 2: Recurrent/metastatic HNSCC who are candidates for first-line anti-PD1 therapy

Cohort 2 subjects will undergo 64Cu-DOTA-ECL1i PET imaging twice, once at baseline prior to the start of anti-PD1 therapy and after 3 cycles of therapy (within 14 days of cycle 4 day 1).

Participants will be followed up via a phone call or in-person visit 24 hours - 14 days after baseline 64Cu-DOTA-ECL1i administration to assess for adverse events. Participants will be followed via medical chart review for standard of care clinical and radiological appointments.

64Cu-DOTA-ECL1i a novel PET imaging tracer that will be provided intravenously (IV) while participants will be positioned supine on the on the scanning table. The injection will be followed with saline flush.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Cohort 1 only: Semiquantitative 64Cu-DOTA-ECL1i PET/CT uptake
Periodo de tiempo: At baseline prior to scheduled surgery (estimated time frame: 1 day)
64Cu-DOTA-ECL1i PET uptake will be assessed using standardized update value maximum (SUVmax). SUV is a decay-corrected measurement of activity per volume of tissue (µCi/mL) divided by the average activity per unit mass in the entire body and/or tumor-to-normal-tissue-ratio. SUVmax is the highest measured uptake of a tracer of a lesion on a PET scan.
At baseline prior to scheduled surgery (estimated time frame: 1 day)
Cohort 1 only: Quantitative 64Cu-DOTA-ECL1i PET/CT uptake
Periodo de tiempo: At time of surgery (total estimated time up to 14 days)
Quantitative 64Cu-DOTA-ECL1i PET uptake will be assessed via a Logan/Patlak analysis to characterize the pharmacokinetics of the tumor. Logan/Patlak is a graphical analysis which uses linear regression to analyze the pharmacokinetics of tracers involving reversible uptake.
At time of surgery (total estimated time up to 14 days)
Cohort 2 only: Semiquantitative 64Cu-DOTA-ECL1i PET/CT uptake
Periodo de tiempo: At baseline (estimated time frame: 1 day)
64Cu-DOTA-ECL1i PET uptake will be assessed using standardized update value maximum (SUVmax). SUV is a decay-corrected measurement of activity per volume of tissue (µCi/mL) divided by the average activity per unit mass in the entire body) and/or tumor-to-normal-tissue-ratio. SUVmax is the highest measured uptake of a tracer of a lesion on a PET scan
At baseline (estimated time frame: 1 day)
Cohort 2 only: Quantitative 64Cu-DOTA-ECL1i PET/CT uptake
Periodo de tiempo: At time of surgery (total estimated time up to 14 days)
Quantitative 64Cu-DOTA-ECL1i PET uptake will be assessed via a Logan/Patlak analysis to characterize the pharmacokinetics of the tumor. Logan/Patlak is a graphical analysis which uses linear regression to analyze the pharmacokinetics of tracers involving reversible uptake.
At time of surgery (total estimated time up to 14 days)
Cohort 1 only: CCR2 expression in tumor tissue
Periodo de tiempo: At time of surgery (total estimated time up to 14 days)
CCR2 expression will be analyzed in tumor tissue specimens obtained from surgical specimens collected at resection and from archival biopsy specimens obtained prior to neoadjuvant therapy. CCR2 expression will be examined using flow cytometry and RT-PCR.
At time of surgery (total estimated time up to 14 days)
Cohort 2 only: Change in 64Cu-DOTA-ECL1i PET uptake from baseline to post-cycle 3 imaging
Periodo de tiempo: At baseline and post cycle 3 imaging (estimated time frame up to 9 weeks)
64Cu-DOTA-ECL1i PET uptake will be assessed using standardized update value maximum (SUVmax). SUV is a decay-corrected measurement of activity per volume of tissue (µCi/mL) divided by the average activity per unit mass in the entire body and/or tumor-to-normal-tissue-ratio. SUVmax is the highest measured uptake of a tracer of a lesion on a PET scan.
At baseline and post cycle 3 imaging (estimated time frame up to 9 weeks)
Cohort 2 only: Objective response
Periodo de tiempo: Enrollment until date of completion of follow-up, date of disease progression, or time of death, whichever occurs first (estimated total time to be 12 months)
Objective response will be assessed according to RECIST 1.1. Objective response is defined as categorized as responder versus non-responder based on best overall response. Responder is defined as best overall response as complete or partial response. Non-responder is defined as best overall response as stable disease or progressive disease.
Enrollment until date of completion of follow-up, date of disease progression, or time of death, whichever occurs first (estimated total time to be 12 months)
Cohort 2 only: Progression-free survival (PFS)
Periodo de tiempo: Start of anti-PD1 treatment to date of disease progression or death from any cause (total estimated time to be 12 months)
PFS is defined from anti-PD1 treatment start date to date of progression or date of death due to any cause. PFS will be analyzed by the Kaplan-Meier method.
Start of anti-PD1 treatment to date of disease progression or death from any cause (total estimated time to be 12 months)
Cohort 2 only: Overall survival (OS)
Periodo de tiempo: Start of anti-PD1 treatment to date of death from any cause (total estimated time to be 12 months)
OS is defined from start of treatment to death due to any cause or last date of follow up. Alive patients are censored at the last follow-up otherwise. OS will be analyzed by the Kaplan-Meier method.
Start of anti-PD1 treatment to date of death from any cause (total estimated time to be 12 months)
