Artificial Tears to Prevent Nasolacrimal Duct Obstruction in Patients Treated With Radioactive Iodine for Thyroid Cancer

The association of radioiodine therapy for the treatment of thyroid cancer with nasolacrimal duct obstruction has been well documented in the medical literature. Prior case reports have documented radioactive iodine detection in the tears of patients following radioiodine therapy. It is possible that radioactive uptake by the cells in the lacrimal sac and nasolacrimal duct lead to inflammation, fibrosis, and obstruction of the tear duct over time. A recent study has shown that the administration of artificial tears decreases the level of detectable radioiodine in the tears of patients undergoing radioiodine therapy for thyroid cancer. The purpose of this study will be to assess whether administering tears after radioactive iodine therapy for thyroid cancer decreases the incidence of nasolacrimal duct obstruction in the two years following radioactive iodine treatment.

177Lu-DOTA-EB-TATE in Adult Patients With Metastatic, Radioactive Iodine Non-Responsive Oncocytic (Hurthle-Cell) Thyroid Cancer

Background: Oncocytic (Hurthle cell) thyroid cancer (HTC) is a rare disease with few treatment options. Researchers are developing a radioactive drug that targets a protein that appears in high numbers on HTC cancer cells. Objective: To test a radioactive drug (177LuDOTA-EB-TATE) in people with HTC. Eligibility: People aged 18 years and older with HTC. The HTC must have failed to respond to conventional radioactive treatment; it must also have spread to other parts of the body. Design: Participants will be screened. They will have a physical exam with blood tests. They will have imaging scans and a test of their heart function. 177LuDOTA-EB-TATE is infused into a vein. Participants will receive 4 infusions spaced 8 to 12 weeks apart. They will stay in the hospital for 4 to 10 days after each infusion. During and after each infusion, participants will remain in a lead-lined room until their radiation levels go down; this usually takes about 24 hours. Participants will have 4 to 6 follow-up visits in the weeks after each infusion. Procedures will vary at each visit, but may include more imaging scans; blood and urine tests; and tests of heart function. Participants will have 2 single-photon emission computerized tomography (SPECT) scans. SPECT scans show where the study drug is sticking to tumors or maybe other parts of their body. They will lie on a table while a machine rotates around them. Participants will fill in questionnaires about how their thyroid condition affects their life. Participants will have follow-ups visits for 5 years after their last study treatment.

Oral Mecobalamin for TKI-Associated Hand-Foot Syndrome in Advanced Thyroid Cancer

This study evaluates the efficacy and safety of oral mecobalamin for the treatment of tyrosine kinase inhibitor (TKI)-associated hand-foot syndrome (HFS) in patients with advanced thyroid cancer. 100 patients will be randomly assigned to receive either routine skin care with topical urea ointment alone (control group) or routine skin care plus oral mecobalamin (0.5 mg three times daily) for 8 weeks. The primary outcome is the proportion of patients with HFS grade improvement at week 8.

Serum Treg/Th17-Related Cytokines and Systemic Inflammatory Indices in Differentiated Thyroid Cancer

This study measures circulating immune-signaling molecules before thyroid surgery to determine whether they differ between patients whose thyroid nodule proves to be a differentiated thyroid carcinoma and patients whose nodule proves to be benign. Adults scheduled for elective thyroidectomy for a thyroid nodule or nodular goiter are enrolled consecutively before surgery, while the nature of the nodule is still unknown. One additional blood tube is obtained during the routine preoperative blood sampling that is performed for every patient on the day of hospital admission, one day before surgery. No separate venipuncture, no additional test, no additional visit and no change to diagnosis, treatment or follow-up is involved. Serum interleukin-17A, measured before surgery, is the primary outcome measure. Additional Treg/Th17-related cytokines, the interleukin-17A to interleukin-10 ratio, and systemic inflammatory indices calculated from the same blood draw are secondary outcome measures. Participants are assigned to the differentiated thyroid cancer group or the benign nodular goiter group after surgery, on the basis of the final histopathology report.

Head and Neck Cancer Strategies

The overall aim is to investigate whether genetic and other molecular markers can improve the diagnosis, assessment of treatment response, and detection of recurrence in patients with head and neck cancer. In the longer term, the project aims to contribute to more individualised treatment strategies for our patients. The project will involve comprehensive analyses of tumour tissue and blood, including extensive genetic sequencing and other molecular profiling. Importantly, the research analyses will not have any implications for the clinical management or treatment of the individual patient included in the study.

The Use of 124-I-PET/CT Whole Body and Lesional Dosimetry in Differentiated Thyroid Cancer

Study rationale High risk patients with differentiated thyroid cancer (DTC) require therapy with 131 I under thyroid stimulating hormone (TSH) stimulation. There are two methods of TSH stimulation endogenous by thyroid hormone withdrawal (THW) leading to hypothyroidism and exogenous by injection of human recombinant TSH (rhTSH Thyrogen). The appropriate 131-I activity utilized for treatment is either based on empiric fixed dosage choice or individually determined activity based on 131 I dosimetric calculations. Although dosimetry utilizing radioactive iodine isotope 131 I enables calculation of maximum safe dose, it does not estimate the tumoricidal activity necessary to destroy the metastatic lesions. The alternative radioactive isotope of iodine -124 I, used for positron emission tomography (PET) imaging, might be used for calculation not only the maximum safe131 I dose, but also to predict the absorbed dose in the metastatic lesions. Study objectives The primary objective of this study is to compare the 124 I -PET/CT lesional and whole body dosimetry in each individual patient with metastatic radioiodine (RAI)-avid thyroid cancer under preparation with rhTSH and THW. The secondary objective is to evaluate the predicted by PET/CT lesional uptake with the early response to therapy. Study design This is a phase 2 pilot prospective cohort study comparing the lesional and whole body dosimetry within each patient undergoing exogenous (rhTSH) and endogenous (THW) TSH stimulation and followed for 5 years. Interventions Each study participant will undergo rhTSH and THW-aided 124 I-PET/CT dosimetric evaluations and will be subsequently treated with THW-aided RAI activity based on dosimetric calculations enabling maximum safe dosage. The patients will be followed in 12+/-3 months intervals for 5 years. Sample size and population This pilot study will include 30 patients with high risk differentiated thyroid cancer presenting with distant and/or loco-regional metastases.

Studies on Tumors of the Thyroid

In addition, blood and tissue samples will be taken for research and genetic studies.

Personalized Treatment in Thyroid Disorders

The Collar Therapy Indicator (CoTI) (A device that is placed in collar around the neck resembling a turtle neck sweater collar with a wire and recording box) has been shown in a single small previously published experience to provide data regarding radioiodine exposure that correlates with conventional methods of measuring I-123 and I-131 uptakes after diagnostic dose administration and/or therapy for thyroid disorders. We hypothesize that the device's continuous measurement capability will permit more accurate estimates of radiation exposure to thyroid tissue than conventionally employed methods assessing fractional uptake at one or a few time points. It may also provide information about the extent of variability in the absorbed radiation dose among patients with thyroid cancer and hyperthyroidism. By providing more complete information about individual patient's exposures, it will facilitate more accurate estimation of the administered I-131 dose requirements for control of hyperthyroidism and thyroid remnant ablation while reducing the need for repeated visits to the clinic for dosimetry measurements. The aims of our project include the following: (1)To compare quantitative imaging-derived thyroid time activity curve to that obtained using the CoTI and to determine the extent to which there is variability in radiation dose predicted using conventional methods to that predicted from measurement of the full Time-Activity Curve (TAC).(2) Evaluate the uptake and clearance kinetics across the 5 patients in each category as proof of principle for a potential larger trial to investigate use of this device in optimizing the administered doses of radioactive iodine to achieve therapeutic goals while minimizing risks of comorbidities, such a post-radioiodine hypothyroidism in patients with Graves' disease.(3)Evaluate patient experience, convenience, and discomfort in using the CoTI device with a survey instrument.

MRG003 Added to Ongoing Treatment After Progression in EGFR-Positive Advanced Thyroid Cancer

This study will evaluate whether adding MRG003 to an ongoing treatment regimen can produce confirmed tumor shrinkage in patients with EGFR-positive advanced thyroid cancer whose cancer initially benefited from that regimen and later progressed. The study will also evaluate the safety of the combinations. Cohort A will include patients with anaplastic or poorly differentiated thyroid carcinoma who previously benefited from lenvatinib plus an anti-PD-1 inhibitor and subsequently progressed. They will continue lenvatinib and the same anti-PD-1 inhibitor, with MRG003 added. Cohort B will include patients with radioactive iodine-refractory differentiated thyroid carcinoma who previously benefited from lenvatinib and subsequently progressed. They will continue lenvatinib, with MRG003 added. MRG003 will be given intravenously at 2.0 mg/kg every 3 weeks. The study plans to enroll 39 participants: 24 in Cohort A and 15 in Cohort B. The first 3 participants in each cohort will undergo an initial 6-week safety assessment before further enrollment is allowed. If additional safety assessment is needed, up to 6 participants who can be evaluated for dose-limiting toxicity will be assessed within the planned cohort enrollment. The main outcome is the proportion of patients in each cohort whose tumors shrink or disappear within 12 weeks after MRG003 starts, with the response confirmed at least 4 weeks later and by Week 18. Scans obtained before MRG003 is added provide the new baseline. Disease control is assessed at Week 12. Other response and survival outcomes are followed for up to 12 months after MRG003 starts. Safety follow-up continues during study treatment and for 90 days after the last study treatment dose, with longer follow-up of unresolved events as needed.

Phase 1/2 Trial of S241656 in Selected RAS/MAPK Mutation- Positive Malignancies

BDTX-4933-101 is a first-in-human, open-label, Phase 1/2 dose escalation, dose optimization and expansion study designed to evaluate the safety and tolerability of S241656 as monotherapy and in combination with other anti-cancer therapies in participants with selected advanced malignancies. The study population for the Dose Escalation part of the study comprises adults with recurrent advanced/metastatic non-small cell lung cancer (NSCLC), Gastrointestinal (GI) cancers, and other solid tumors harboring KRAS, HRAS, NRAS, BRAF, and/or CRAF (Rapidly Accelerated Fibrosarcoma (RAF1)) mutations or alterations. A dose optimization part in adults with NSCLC may follow the dose escalation phase if the sponsor, in consultation with the safety review committee, decides it is necessary to further characterize the optimal dose. However, the study may also proceed directly to the expansion phase. The study population for the Dose Expansion part of the study comprises adults with advanced/metastatic NSCLC with KRAS and/or BRAF mutations, and with Pancreatic Ductal AdenoCarcinoma (PDAC), ColoRectal Cancer (CRC), and Biliary Tract Cancer (BTC) with KRAS, HRAS, NRAS, BRAF, and/or CRAF (RAF1) mutations and alterations. All patients will self-administer S241656 orally in 28-day cycles until disease progression, toxicity, withdrawal of consent, or termination of the study.
