AI-Summary

What this Trial Is About

This research is being done to determine the efficacy of selpercatinib to restore radioactive iodine (I-131 NaI) uptake and allow for I-131 treatment in people with RET fusion-positive radioiodine-refractory thyroid cancer. This research study involves the study drug selpercatinib in combination with standard of care treatments, I-131 and thyrotropin alfa (rhTSH).

Eligibility Criteria

Eligible

You may qualify if you...

  • Participants must have confirmed follicular-derived nonanaplastic thyroid cancer that is metastatic and/or unresectable with a known RET gene fusion.
  • Tumor RET fusion detection can be by tumor tissue or liquid biopsy using NGS, qPCR, or FISH.
  • Participants 18 years or older must have measurable disease per RECIST v1.1; ages 12 to under 18 may have evaluable or measurable disease.
  • No single tumor deposit may exceed 4.0 cm in greatest dimension.
  • Participants must have radioiodine-refractory disease defined by specific criteria related to iodine uptake and progression.
  • Total cumulative radioactive iodine treatment dose must not exceed 500 mCi.
  • Disease must be asymptomatic or minimally symptomatic as judged by the investigator.
  • Prior external beam radiotherapy allowed; disease within prior radiotherapy field must be measurable.
  • No more than one prior systemic therapy for radioiodine-refractory thyroid cancer allowed; prior RET-specific kinase inhibitor therapy is not allowed.
  • At least 28 days must have passed since prior radiation or major surgery and systemic therapy (excluding thyroid hormone replacement).
  • Participants must be 18 years or older; ages 12 to under 18 allowed with assent and consent.
  • ECOG performance status ≤1 for ages 16 and older; Lansky score ≥60 for ages 12 to under 16.
  • Life expectancy greater than 12 months.
  • Ability to swallow medications with no gastrointestinal abnormalities affecting absorption.
  • Adequate organ and marrow function as defined by specified bloodwork within 7 days prior to treatment.
  • Normal serum potassium, calcium, and magnesium levels within institutional normal range.
  • HIV-positive participants on effective therapy with undetectable viral load within 6 months are eligible.
  • Participants with chronic HBV must have undetectable viral load if on suppressive therapy.
  • Participants with treated or cured HCV are eligible; those currently on treatment must have undetectable viral load.
  • Participants with treated brain metastases must be asymptomatic with no evidence of progression on follow-up imaging.
  • Participants with prior or concurrent malignancy without interference to safety or efficacy assessment are eligible.
  • Participants with known or current cardiac disease must have NYHA class 2B or better.
  • Women of child-bearing potential and men must use effective contraception during and 6 months after treatment.
  • Women of child-bearing potential must have a negative pregnancy test within 7 days prior to treatment and not breast-feed within 2 months before and during treatment and for 1 week after last dose.
  • Ability and willingness to sign informed consent.
Not Eligible

You will not qualify if you...

  • Chemotherapy, MKI, or radiotherapy within 4 weeks prior to study.
  • I-131 NaI treatment within 12 months prior to study.
  • Unresolved adverse events from prior anti-cancer therapy above Grade 1, except alopecia.
  • Use of any other investigational agents.
  • Symptomatic CNS metastasis or lesions threatening spinal cord compression.
  • Clinically significant active cardiovascular disease, recent myocardial infarction within 6 months, or prolonged QTcF >470 msec.
  • Uncontrolled hypertension (>160/95 mm Hg) at screening; may be re-screened after treatment.
  • Active uncontrolled infections or serious ongoing illnesses preventing safe participation.
  • Uncontrolled symptomatic hyperthyroidism or hypothyroidism.
  • Symptomatic hypercalcemia or hypocalcemia.
  • Active bleeding or significant risk for hemorrhage.
  • Use of medications known to cause QTc prolongation.
  • Clinically significant malabsorption or gastrointestinal conditions affecting drug absorption.
  • Other uncontrolled serious illnesses interfering with study therapy.
