This phase III trial compares the effect of adding cetuximab to pembrolizumab versus pembrolizumab alone in treating patients with head and neck squamous cell carcinoma (HNSCC) that has come back after a period of improvement (recurrent) and/or that has spread from where it first started (primary site) to other places in the body (metastatic). Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of tumor cells. This may help keep tumor cells from growing. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving cetuximab and pembrolizumab together may be more effective at treating patients with recurrent and/or metastatic HNSCC than pembrolizumab alone.

Multiple myeloma (MM) is a plasma cell disease characterized by the growth of clonal plasma cells in the bone marrow. The purpose of this study is to assess the safety and toxicity of etentamig (ABBV-383) when co-administered with pomalidomide-dexamethasone (Pd), lenalidomide-dexamethasone (Rd), or daratumumab-dexamethasone (Dd), in adult participants with relapsed/refractory (R/R) multiple myeloma (MM). Adverse events and change in disease activity will be assessed. Etentamig is an investigational drug being developed for the treatment of R/R MM. Study doctors put the participants in groups called treatment arms. Etentamig co-administered with Pd, Rd, or Dd, will be explored. Each treatment arm receives a different treatment combination depending on stage of the study and eligibility. This study will include a dose escalation phase to determine the best dose of etentamig, followed by a dose expansion phase to confirm the dose. Approximately 320 adult participants with R/R MM will be enrolled in the study in approximately 48 sites worldwide. Participants will receive intravenous (IV) etentamig co-administered with oral/IV Pd, oral/IV Rd, or oral/IV/subcutaneous (SC) Dd in 28-day cycles. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.

This is a single-arm, non-inferiority study in which patients who have achieved a very good partial response (VGPR) or better, according to International Myeloma Working Group (IMWG) response criteria, following 6 to 9 months of treatment with teclistamab, a B-cell maturation antigen (BCMA)-directed T-cell engager (anti-BCMAxCD3 bispecific antibody), will be offered monitored drug discontinuation. Teclistamab is typically dosed on a regular schedule (every 1-4 weeks) indefinitely until disease progression ("continuous therapy"). Here, a limited-duration regimen will be studied in which patients achieving ≥VGPR after 6-9 months of standard teclistamab dosing will discontinue therapy and resume if laboratory or clinical parameters suggest early disease progression ("limited-duration therapy"). Patients will enter the clinical trial protocol after completing 6-9 months of standard teclistamab monotherapy and achieving ≥VGPR. The study's hypothesis is that the failure probability six months after stopping teclistamab in this patient population will be non-inferior compared to that of historical controls treated with continuous therapy. Reducing drug exposure may be beneficial by reducing risk of infection and reducing anti-BCMA selective pressure toward generation of BCMA-negative relapses. Analysis of minimal residual disease (MRD), tumor features, and bone marrow microenvironment parameters, which will be pursued as exploratory correlative analyses in this study, may identify factors that predict durable response to limited-duration therapy and thereby enable more precise selection of patients likely to benefit from this approach. A subset of patients will be enrolled on a biomarker study for analysis of these exploratory endpoints.

The prognosis for patients with localized pancreatic adenocarcinoma who are not surgical candidates is poor. Patients characterized as having "borderline resectable" disease treated with preoperative chemo-radiotherapy fair somewhat better - although many of these patients are not converted to resectability. It may be argued that intensification of local and regional therapy might 1.) Increase the share of patients able to undergo curative surgery and 2.) Improve the local disease control interval and extend survival for patients who remain unresectable. Therefore, the purpose of this research study is to determine if an increase in the number of surgical resection pancreatic adenocarcinoma is higher than historical data by using a combined treatment of proton radiation with capecitabine (oral chemotherapy).

This phase II/III trial compares the addition of nivolumab to the usual treatment of paclitaxel and ramucirumab to paclitaxel and ramucirumab alone in treating patients with gastric or esophageal adenocarcinoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Ramucirumab is a monoclonal antibody that may prevent the growth of new blood vessels that tumors need to grow. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Adding nivolumab to ramucirumab and paclitaxel may work better to treat patients with advanced stomach or esophageal cancer.
