Vemurafenib Plus Copanlisib in Radioiodine-Refractory (RAIR) Thyroid Cancers

Completed · Phase 1

Conditions studied: Thyroid Carcinoma, Thyroid Cancer, Thyroid Cancer, Follicular, Thyroid Cancer (Follicular Cell), Thyroid Cancer, Papillary, BRAF V600E Mutation Positive

In brief

The purpose of this study is to develop a new drug treatment to reverse tumor resistance to radioiodine in BRAF mutant tumors so that radioiodine can be given to shrink tumors. This study is also being done to find out the highest doses of copanlisib and vemurafenib that, when given in combination, do not cause serious side effects, and whether the study treatment will make radioiodine therapy work better in patients with BRAF-mutant thyroid cancers.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histologically or cytologically confirmed thyroid carcinoma of follicular origin (including papillary, follicular, and poorly differentiated subtypes and their respective variants).
• A tumor sample (primary, recurrent, or metastatic tumors) possessing a BRAF V600 mutation, as confirmed in a CLIA-certified laboratory or using an FDA-approved assay
• Measurable disease by RECIST v1.1 (tumors in previously irradiated fields may be considered measurable if there is evidence of tumor progression after radiation treatment)
• RAIR disease, as defined by any one of the following:
• A metastatic lesion that is not RAI-avid on a diagnostic radioiodine scan
• An RAI-avid lesion that remained stable in size or progressed despite RAI treatment before entry in this study (there are no size limitations for the index lesion used to satisfy this entry criterion)
• The presence of at least 1 FDG-avid lesion
• No receipt of treatment for thyroid cancer, defined as:
• No I-131 therapy < 6 months before initiation of the protocol (time of initiation of the protocol is defined as the first day of drug therapy with vemurafenib and copanlisib); diagnostic activities of I-131 (0-10m Ci) are allowed within 6months of initiating the protocol
• No external beam radiation therapy <4 weeks before initiation of the protocol
• No chemotherapy or targeted therapy including TKIs <4 weeks (or <5 half lives of the drug) before the initiation of this protocol
• Age of ≥ 18 years
• ECOG performance status ≤ 2 or Karnofsky Performance Score (KPS) ≥ 70%
• Tissue from the primary tumor or metastases available for correlative studies. Either a paraffin block or at least 20 unstained slides are acceptable (30 unstained slides is ideal); if <20 unstained slides are available, and a paraffin block is not available, the patient may be able to participate at the discretion of the investigator
• Able to swallow and retain an orally administered pill without any clinically significant gastrointestinal abnormalities that may alter absorption, such as malabsorption syndrome or major resection of the stomach or bowels
• Agree to undergo 2 research biopsies of (a) malignant lesion(s). Tumor tissue obtained before study consent or treatment can also be submitted in lieu of performance of the first pretreatment biopsy if the Principal Investigator deems it to be of sufficient quantity/quality/timeliness (tumor tissue obtained more than 3 years from time of study consent would not be eligible). Patients may be exempt from biopsy if (1) the investigator or person performing the biopsy judges that no tumor is accessible for biopsy, (2) the investigator or person performing the biopsy feels that the biopsy poses too great of a risk to the patient, or (3) the patient's platelet count is <100,000/mcL or the patient cannot be safely removed from anticoagulation therapy (if the anticoagulation therapy needs to be temporarily held for the biopsy procedure). If the investigator deems a second research biopsy to be high risk, the patient may be exempt from the second biopsy.
• Screening laboratory values meeting the following criteria:
• WBC ≥ 2000/µL
• Neutrophils ≥ 1500/µL
• Platelets ≥ 100 × 10\^3/µL
• Hemoglobin >9.0 g/dL
• Lipase ≤ 1.5 × ULN
• AST/ALT ≤ 3 × ULN
• Total bilirubin ≤ 1.5 x ULN (except subjects with Gilbert syndrome, who can have total bilirubin <3.0 mg/dL)
• Serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 40 mL/min (if using the Cockcroft-Gault formula below):

You may not qualify if…

• Untreated metastatic brain or leptomeningeal tumors (metastatic brain or leptomeningeal tumors treated with radiation and/or surgery are allowed)
• Prior malignancy if diagnosed and treated within 2 years of trial drug initiation (with the exception of nonmelanoma skin cancers or Stage I cancers treated with curative intent).Patients may be included if they have completed therapy for a prior malignancy >2 years before drug initiation and currently have no evidence of disease
• Inability to follow a low-iodine diet or requiring a medication with a high content of iodide (amiodarone)
• Current congestive heart failure class >2, as defined by the New York Heart Association functional classification system
• Myocardial infarction < 6 months before the initiation of protocol
• Unstable angina (angina symptoms at rest) or new-onset angina (begun within the last 3 months)
• Uncontrolled hypertension (blood pressure >150/90, despite optimal medical management)
• Uncontrolled type I or II diabetes mellitus, as judged by the investigator, or Hgb A1C of >8.5
• Arterial or venous thrombotic event or embolic event, such as a cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis, or pulmonary embolism, within 3 months before the start of study medication
• Nonhealing wound, ulcer, or bone fracture (tumor-related nonhealing wounds are allowed)
• Active, clinically serious infections CTCAE v5.0 grade >2
• History of concurrent condition of interstitial lung disease and/or severely impaired lung function
• Known history of HIV infection (all patients must be screened for HIV up to 28 days before start of study)
• Seizure disorder requiring medication
• Therapy with a prohibited concomitant medication that cannot be temporarily held (at least 2 weeks before initiation of vemurafenib plus copanlisib until 1 week after the last dose) or replaced with a nonprohibited concomitant medication
• Systemic corticosteroid therapy at a daily dose >15 mg prednisone or equivalent (previous corticosteroid therapy must be stopped or reduced to the allowed dose at least 7 days before study registration)
• Cytomegalovirus (CMV) PCR-positive at baseline
• Evidence or history of a bleeding diathesis or any hemorrhage or bleeding CTCAE v5.0 grade ≥ 3 within 4 weeks before the start of study protocol
• HBV or HCV infection. All patients must be screened for HBV and HCV up to 28 days before the start of study medication using the routine hepatitis virus laboratorial panel. Patients positive for HBsAg or HBcAb will be eligible if they are negative for HBV-DNA (these patients should receive prophylactic HBV antiviral therapy). Patients positive for anti-HCV antibody will be eligible if they are negative for HCV-RNA
• Known hypersensitivity to any of the test drugs, test drug classes, or excipients in the formulation
• Substance abuse or medical, psychological, or social conditions that may interfere with the patient's participation in the study or evaluation of the study results
• Patients who are pregnant
• Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 6 months after the last administration of study treatment. Highly effective contraception methods include:
• Total abstinence (when this is in line with the preferred and usual lifestyle of the patient). Periodic abstinence (e.g., calendar, ovulation, symptothermal, postovulation methods) and withdrawal are not acceptable methods of contraception
• Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy, or tubal ligation at least 6 weeks before taking study treatment. In cases of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone-level assessment (FSH level in the postmenopausal range) is this acceptable
