Improving Dental Care for Patients With Head and Neck Tumors

This prospective survey study investigates knowledge, attitudes, experiences, and practices related to dental care in patients with head and neck cancer among affected patients and dentists. Participants complete an anonymous online questionnaire before and after receiving written, guideline-based information. The study aims to evaluate whether targeted educational materials improve knowledge and perceptions regarding dental care in the context of head and neck cancer treatment.

A Clinical Study to Compare BupiZenge With Lidocaine for Pain Due to Oral Mucositis in Patients With Head and Neck Cancer.

Most patients who receive radiation therapy for head and neck cancer develop painful sores in the mouth called oral mucositis. For many of them, these sores are severe and result in debilitating pain. The sores usually start in the third week of radiation and last aboutfive weeks, often continuing for two weeks after treatment ends. Current pain treatments, for instance lidocaine solution, only give short-lasting pain relief. BupiZenge is a lozenge that dissolves slowly in the mouth and contains bupivacaine. Bupivacaine is a long-acting pain-relieving medicine and has been safely used for many years for both children and adults, and its safety profile is well understood. The BupiZenge lozenge is designed to give longer and more reliable pain relief for patients with mucositis in their mouth. This study will check if BupiZenge works better to reduce pain than lidocaine, and if better pain control improves quality of life and reduces the need for strong pain medicines like opioids. The main goal is to see how much mouth pain decreases after taking BupiZenge compared to lidocaine. This is measured by asking the patients to rate their pain score on a scale from 0 (no pain) to 10 (worst possible pain). This is done at different time-points, from before the dose until three hours after dose on the last day of radiotherapy. The study will include 150 adults, both women and men, aged 18 to 80 years, who have head and neck cancer and are scheduled to receive radiotherapy, with or without chemotherapy. These patients will be randomly assigned to one of the treatment groups. The first is BupiZenge, which is a lozenge containing bupivacaine, which dissolves slowly in the mouth. The second is lidocaine, which is a liquid solution for use in the mouth that you gurgle or swish around in the mouth. The study begins with a combined screening and run-in period that can last up to five weeks. During radiotherapy, patients record their mouth pain each day using a number scale from 0 (no pain) to 10 (worst possible pain). If the pain score is at least 4 (moderate pain) and they have developed mucositis in the mouth within 5 weeks, patients are randomly assigned to receive either BupiZenge or Lidocaine. Treatment continues at least until radiotherapy is completed. If the patient has pain and mouth sores, and the treatment is working well, it may continue after radiotherapy ends, but only until the sores heal or for a maximum of six weeks in total, whichever occurs first. After treatment ends, there is a 30-day follow-up period.

SL-28 for Advanced Solid Tumours

Second Life Therapeutics is developing SL-28, an allogeneic, non-genetically modified cell-based therapy for the treatment of advanced solid tumours. The company has recently demonstrated a novel, non-genetic approach to modulate immune cell activity through targeted manipulation of the Universal Receptive System. The purpose of this open label, multi-center clinical trial is to evaluate the anti-tumor activity, safety, and pharmacokinetics, single-agent SL-28 in patients with a diverse array of solid tumors. The study includes an initial Phase 1 dose escalation to determine recommended dose(s) for expansion of SL-28 as a monotherapy and Phase 2 expansion cohorts. The study will enroll patients with advanced solid tumours, including those who failed previous lines of chemo- and immunotherapies.

Integrated Early-CARE for Head & Neck Cancer.

In Portugal, approximately 2,424 new cases of head and neck cancer are diagnosed each year, of which 60% are already at an advanced stage, presenting with intense pain and dysphagia (difficulty swallowing). There is also marked social isolation due to communication difficulties, economic hardship, and facial disfigurement (altered facial appearance). As a result, patients frequently face challenges in accessing specialised palliative care services, encountering delays, fragmentation, or a complete absence of such care. The i-CARE-HN study is the solution: investigators aim to integrate outpatient palliative care with oncological treatment -namely chemoradiotherapy -at an earlier stage of the disease-when it is still limited to the throat and neck region, without metastasis (spread to other organs). This means multidisciplinary support from the outset of oncological treatment - symptom control, psychological support, and quality of life - without delaying the cure. It is like giving the patient a 'shield' against suffering, enabling them to complete treatment more efficiently. In the i-CARE-HN study, early palliative care aims to better manage patients' symptoms (such as pain, difficulty speaking, swallowing, breathing, dry mouth, loss of appetite, and anxiety), to clarify doubts, to support therapeutic decisions, and to strengthen communication between the patient and the team, without replacing the primary oncological treatment. Rather than waiting for symptoms to worsen before seeking help, this support will be provided throughout treatment with chemotherapy and radiotherapy. Through this simultaneous integration of outpatient palliative care into oncological treatment, investigators hope to improve patients' symptoms and quality of life, as well as clinical outcomes: fewer treatment interruptions, improved treatment tolerability, fewer emergency hospitalisations, and greater overall survival. Investigators will want to know how patients are feeling throughout the process, and to that end, will invite them to complete a survey at several points during the study. Responses to the questionnaires are critical to enabling the medical team to rapidly identify which participating patients present with the most significant symptoms and the greatest risk of complications. This study plans to recruit 64 patients aged 18 years or older, with a recent diagnosis of locally advanced, inoperable cancer, being followed on an outpatient basis at the IPO de Coimbra, IPO do Porto, and ULS de Coimbra, who will be invited to participate in the study. Should the patient agree to participate, some baseline data will be collected, and patients will subsequently be randomly assigned to one of two groups: one group will receive isolated chemoradiotherapy (standard treatment: cisplatin 100 mg/m² every 3 weeks- days 1, 22, and 49- and daily radiotherapy 70 Gy in 35 fractions over 7 weeks) and the other group will receive chemoradiotherapy alongside palliative care, on an outpatient basis (access to palliative care consultations). Patients randomised to the standard treatment group (chemoradiotherapy without a structured early palliative care intervention) will not have palliative care appointments systematically scheduled. However, should a referral to palliative care be requested, the patient may be directed to that clinical department.

REPROton-HN: Prospective Observational Study on Proton Re-irradiation for Locoregional Recurrences of Head and Neck Tumors

Some patients with head and neck cancer may develop a tumor recurrence in an area that has already been treated with radiotherapy. In these situations, surgery is not always possible, and giving radiotherapy again can be challenging because nearby healthy tissues and organs may already have received high radiation doses. The REPROton-HN study is evaluating the use of proton therapy for these patients. Proton therapy is a type of radiation treatment that can deliver radiation more precisely to the tumor while reducing exposure to surrounding healthy tissues. The aim of the study is to better understand how safe and effective proton therapy is when used as a second course of radiation treatment. Researchers will monitor side effects, tumor control, survival, and patients' quality of life. The results may help improve treatment planning and identify which patients are most likely to benefit from proton therapy in the future.

Intratumoral Injection of Recombinant Human Endostatin Adenovirus (EDS01) for the Treatment of Recurrent or Metastatic Head and Neck Tumors

This single-center, Phase 1 study is evaluating the safety, tolerability, and preliminary antitumor activity of recombinant human endostatin adenovirus injection (EDS01) given by intratumoral injection in combination with toripalimab in adults with recurrent or metastatic head and neck tumors, including nasopharyngeal carcinoma, whose disease has progressed after platinum-based systemic therapy or who are not suitable for further platinum treatment. A total of 9 participants will be enrolled in 3 planned dose groups of EDS01. EDS01 will be injected directly into an accessible tumor lesion on Days 0 and 7, and toripalimab 240 mg will be administered intravenously on Day 1 of each treatment cycle for up to 4 cycles, unless disease progression or unacceptable toxicity occurs. The study will evaluate treatment-related adverse events as well as preliminary efficacy outcomes, including tumor response, disease control, and time to progression, using clinical assessments, laboratory tests, imaging, and follow-up after treatment.

Postoperative Radiotherapy Combined With Nimotuzumab Followed by Benmelstobart in High-Risk Patients With Head and Neck Squamous Cell Carcinoma

A Multicenter, Randomized, Controlled, Open-Label, Phase III Clinical Trial.To evaluate the efficacy and safety of postoperative radiotherapy combined with Nimotuzumab followed by Benmelstobart in high-risk patients with head and neck squamous cell carcinoma who are ineligible for cisplatin chemotherapy. The primary endpoint is disease-free survival (DFS). A total of 185 patients will be enrolled in both the study group and the control group, respectively, with a total planned enrollment of 370 patients. Enrollment is expected to be completed within 2 years, followed by a 3-year follow-up period after the last patient is enrolled.

Protein Supplementation for Radiation- Induced Oral Mucositis in Head and Neck Cancer Patients Receiving Radiotherapy

This clinical trial aims to evaluate whether oral supplementation with a hydrolyzed whey protein formula ("TeYiShu") can reduce the incidence of severe radiation-induced oral mucositis and improve prealbumin levels in patients undergoing radiotherapy for head and neck squamous cell carcinoma (HNSCC). The study will compare the protein supplement to an isocaloric placebo without protein, maintaining equal caloric intake across groups. Participants will receive either the protein supplement or placebo daily throughout the course of radiotherapy. The primary outcomes are the incidence of grade ≥3 oral mucositis, assessed using the Radiation Therapy Oncology Group (RTOG) Acute Radiation Morbidity Scoring Criteria, and changes in serum prealbumin levels. Secondary outcomes include the time to onset and resolution of mucositis, nutritional status changes, adverse events, and quality of life measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck Cancer Module (EORTC QLQ-H\&N35).

FL-261 Imaging for Cancer Diagnosis and Staging

c-MET is a receptor tyrosine kinase overexpressed in multiple malignancies and associated with tumor progression, therapeutic resistance, and poor prognosis, while showing limited expression in normal tissues, making it an attractive imaging and therapeutic target. Current assessment relies on invasive biopsy and is limited by tumor heterogeneity and sampling bias. FL-261 is a novel c-MET-targeting ligand with high affinity and specificity, favorable tumor uptake and retention, rapid background clearance, and good preclinical safety. It can be radiolabeled for both diagnostic imaging and potential theranostic applications. This first-in-human study will evaluate \[68Ga\]Ga-FL-261 PET or \[111In\]In-FL-261 SPECT imaging in patients with advanced malignancies, including non-small cell lung cancer, colorectal cancer, and head and neck cancer. The study aims to assess safety, biodistribution, and tumor-targeting capability, and to explore its diagnostic value by correlating imaging findings with histopathological c-MET expression.

Longitudinal Oral Health Changes After Head and Neck Radiotherapy

This prospective observational study evaluates how head and neck radiotherapy affects oral health over time. Patients with head and neck cancer undergoing standard radiotherapy are followed from before treatment through multiple post-treatment visits. Changes in periodontal health, dental status, salivary function, and patient-reported oral health quality of life are assessed. The study aims to better understand the long-term oral complications of radiotherapy and to support improved preventive and supportive dental care for cancer patients.

A Phase 1b/2 Study of the Safety and Efficacy of the Monoclonal Antibody OM-RCA-01 in Patients With Metastatic Tumors Expressing Fibroblast Growth Factor Receptor 1

One of the most relevant targets in the field of novel targeted anticancer therapy is the family of receptors to fibroblast growth factor receptors (FGFRs). FGFR1 is the main representative of the FGFR family. The goal of this clinical trial is to learn if monoclonal anti-FGFR1 antibody (OM-RCA-01) works to treat metastatic cancers expressing FGFR1. It will also learn about the safety of drug OM-RCA-01. The main questions it aims to answer are: 1. What medical problems do participants have when receiving drug OM-RCA-01? 2. What dose of the drug should patients receive in the next studies? 3. Does tumor growth slow down in patients receiving OM-RCA-01? All patients in this study will receive the antibody treatment. The drug will be given through a vein (by IV infusion) every two weeks, for as long as the disease remains under control and the treatment is well tolerated.
