RBS2418 (investigational product) is a specific immune modulator, working through
ectonucleotide pyrophosphatase/phosphodiesterase I (ENPP1), designed to lead to anti-tumor
immunity by increasing endogenous 2'-3'-cyclic guanosine monophosphate-adenosine
monophosphate (cGAMP) and adenosine triphosphate (ATP levels) and reducing adenosine
production in the tumors. RBS2418 has the potential to be an important therapeutic option for
subjects both as monotherapy and in combination with checkpoint blockade. This study is an
open-label, multi-site Phase 1a/1b study of RBS2418, a selective ENPP1 inhibitor, in
combination with pembrolizumab or as a monotherapy in subjects with advanced unresectable,
recurrent or metastatic tumors.

This is a Phase 1/2, open-label, non-randomized, 4-part Phase 1 trial to determine the safety
profile and identify the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D)
of INBRX 106 administered as a single agent or in combination with the anti-PD-1 checkpoint
inhibitor (CPI) pembrolizumab (Keytruda).

This phase I trial evaluates the safety and effectiveness of using two imaging techniques, indium In 111 panitumumab (111In-panitumumab) with single photon emission computed tomography (SPECT)/computed tomography (CT) and panitumumab-IRDye800 fluorescence imaging during surgery (intraoperative), to detect disease in patients with head and neck cancer. 111In-panitumumab is an imaging agent made of a monoclonal antibody that has been labeled with a radioactive molecule called indium In 111. The agent targets and binds to receptors on tumor cells. This allows the cells to be visualized and assessed with SPECT/CT imaging techniques. SPECT is special type of CT scan in which a small amount of a radioactive drug is injected into a vein and a scanner is used to make detailed images of areas inside the body where the radioactive material is taken up by the cells. CT is an imaging technique for examining structures within the body by scanning them with x-rays and using a computer to construct a series of cross-sectional scans along a single axis. Panitumumab-IRDye800 is an imaging agent composed of panitumumab, a monoclonal antibody, linked to a fluorescent dye called IRDye800. Upon administration, panitumumab-IRDye800 targets and binds to receptors on tumor cells. This allows the tumor cells to be detected using fluorescence imaging during surgery. Adding 111In-panitumumab SPECT/CT imaging to intraoperative panitumumab-IRDye800 fluorescence imaging may be more effective at detecting disease in patients with head and neck cancer.

This phase I trial tests the safety and effectiveness of indium In 111 panitumumab (111In-panitumumab) for identifying the first lymph nodes to which cancer has spread from the primary tumor (sentinel lymph nodes) in patients with head and neck squamous cell carcinoma (HNSCC) undergoing surgery. The most important factor for survival for many cancer types is the presence of cancer that has spread to the lymph nodes (metastasis). Lymph node metastases in patients with head and neck cancer reduce the 5-year survival by half. Sometimes, the disease is too small to be found on clinical and imaging exams before surgery. 111In-panitumumab is in a class of medications called radioimmunoconjugates. It is composed of a radioactive substance (indium In 111) linked to a monoclonal antibody (panitumumab). Panitumumab binds to EGFR receptors, a receptor that is over-expressed on the surface of many tumor cells and plays a role in tumor cell growth. Once 111In-panitumumab binds to tumor cells, it is able to be seen using an imaging technique called single photon emission computed tomography/computed tomography (SPECT/CT). SPECT/CT can be used to make detailed pictures of the inside of the body and to visualize areas where the radioactive drug has been taken up by the cells. Using 111In-panitumumab with SPECT/CT imaging may improve identification of sentinel lymph nodes in patients with head and neck squamous cell cancer undergoing surgery.

This phase I/II trial studies the side effects and best dose of a combination of gabapentin and ketamine and to see how well it works to prevent acute and chronic pain in patients receiving chemotherapy and radiation therapy (chemoradiation) for head and neck cancer that has spread to nearby tissue or lymph nodes (locally advanced). Gabapentin is a medication that is commonly used to treat nerve related pain. Specifically, it has been used to treat pain involving the mouth, throat and nasal passages in head and neck cancer patients treated with radiation. Ketamine is a type of general anesthetic that blocks pathways to the brain involved with sensing pain. This trial may help doctors determine how patients tolerate the combination of gabapentin and ketamine and to find the correct dosing for ketamine in those taking gabapentin. This will be the basis for a future, larger study to look at how effective this combination is at reducing and/or preventing pain in head and neck cancer patients.
