NCT04524442

Brief Summary

The purpose of the study was to evaluate the effect of arginine/lysine solution administration on serum potassium levels. A systematic assessment of serum potassium levels was performed during infusion and up to 24 hours post start of infusion compared to baseline.

Outcome Measures

Primary Outcomes (1)

  • Mean Change From Baseline in Serum Potassium Levels Over 24 Hours

    Serum potassium levels at each collection time point will be measured at local laboratories of study sites using validated methods. The potassium concentration results will be summarized descriptively and will include mean change, maximum change, time to the maximum change, and the overall dynamics of the potassium concentration curve during and after the arginine/lysine infusion.

    Day 0/Infusion Day (Hour 0, Hour 2, Hour 4, Hour 6, Hour 8, Hour 12, Hour 24)

Secondary Outcomes (9)

  • Percentage of Participants With Treatment Adverse Events (AEs) & Serious Adverse Events (SAEs)

    Day 0/Infusion Day up to 48 hours post infusion

  • Number of Participants With Notable Changes in Vital Signs

    Day 0/Infusion Day (0, 2, 4, 6, 8, 12 and 24 hours)

  • Number of Participants With Notable Changes in Electrocardiogram (ECG)

    Day 0/Infusion Day (0, 4, 8 and 24 hours)

  • Number of Participants With Notable Changes in Hematology Parameters

    Day 0/Infusion Day (0 and 24 hours)

  • Number of Participants With Notable Changes in Chemistry Parameters

Study Arms (1)

GEP-NET

EXPERIMENTAL

One dose of arginine/lysine solution administered intravenously over a 4-hour period

Drug: arginine/lysine

Interventions

1000 milliliters (mL) administered at a constant rate of 250 mL per hour

Also known as: LysaKare
GEP-NET

Eligibility Criteria

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

You may qualify if:

  • Patients with somatostatin receptor positive gastroenteropancreatic neuroendocrine tumours (GEP-NETs), who are eligible for the treatment with Lutathera as per Lutathera label indication.
  • Patients who have provided a signed informed consent form to participate in the study, obtained prior to the start of any protocol related procedures.

You may not qualify if:

  • Pre-existing hyperkalemia (\>6.0 mmol/L at screening) if not adequately corrected before starting the LysaKare (arginine/lysine) infusion. For Poland only, pre-existing hyperkalemia (\> 5.5 mmol/L at screening) if not adequately corrected before starting the LysaKare (arginine/lysine) infusion.
  • Instances when Lutathera is not recommended per the Lutathera Summary of Product Characteristics (SmPC).
  • Pregnancy or lactation, positive pregnancy test at screening or pre-dose based on the contraindication for Lutathera.
  • Any significant medical or social condition which may interfere with the subject's ability to comply with the study visit schedule or the study assessments.
  • Patients who have received any investigational agent within the last 30 days.
  • Patients that have received a dose of Lutathera prior to the screening visit or are scheduled for Peptide Receptor Repeat (PRRT) treatment within 7 days of the study infusion of arginine/lysine solution.
  • \- Pre-existing hyperkalemia (\> 5.5 mmol/L at screening) if not adequately corrected before starting the arginine/lysine solution infusion.
