Stepwise Heat-Denaturated Protein Introduction for Tolerance Induction in Food Allergy

WP 1: Gradual introduction of less heated cow's milk proteins in 20'-cooked cow's milk tolerant children. When inclusion criteria are met and informed consent from the parents (and when old enough, assent from the children) is obtained, children will be included in the trial. During the inclusion visit an open 20' cooked milk oral food challenge (OFC) needs to be passed in the hospital. Each visit a validated pedQuality of life (QoL) questionnaire will be taken and blood will be drawn to determine baseline specific IgE (sIgE) and IgG4 to cow's milk. Subjects (n=75) are randomized in a 1/1/1 ratio across three arms for 12 months to study the arm's tolerance inducing capacity (see Arms and Interventions for more information). After 6 months patients are invited for an intermediate visit. After 12 months, a OFC with unheated milk will be performed in all children during their challenge visits. Three months after the OFC, the children will be invited for a termination visit. Children who did not pass the OFC with unheated cow's milk after 12 months, will be invited to an observational 48 months follow-up study, in order to later-on retrieve the potential moment of complete cow's milk tolerance induction by clinical files. WP2: Study of the immunological mechanisms (Treg and Breg induction and switch to IgG4-producing B cells). Venous blood will be taken from all 75 children recruited for WP1 at enrolment and at the challenge and termination visit and from 15 healthy age-matched children, after obtaining children's oral or written assent (where appropriate) and parent's informed consent. Peripheral blood mononuclear cells (PBMCs) will be isolated and stimulated by cow's milk proteins as well as a positive control. Membrane markers associated with regulatory activity on T cells will be studied by flow cytometry (FC), as well as cytokine production in the supernatant by meso scale discovery. Furthermore, B cells will be studied after PBMC stimulation by FC. Cow's milk specific IgG4 and cytokine production will also be studied in this culture supernatant. WP3: In vitro BATs to mimic the outcome of OFC. In vitro Basophil activation tests (BATs) will be fine-tuned by preparing extracts for 20', 15', 10', 5' cooked and fresh cow's milk. Fine-tuning will include the comparison of new protein extract batches with the first batches, the absence of background basophil activation upon contact with the lowest dose of allergen extract and the comparison of basophil activation of healthy and of allergic children in different phases of cow's milk tolerance, who should show differences depending on the grade of tolerance. After fine-tuning, BATs will be performed as described above with 3 (or 5) extracts from cow's milk at baseline, challenge visit and termination visit in all children recruited within the study.

Bicalutamide and Abemaciclib in Inoperable or Metastatic Androgen Receptor-positive Triple-negative Breast Cancer

This study is a phase II single arm clinical trial. Phase II clinical trials test the safety and effectiveness of an intervention to learn whether the intervention works in treating a specific disease. In this study, the investigators will include patients with locally advanced unresectable or metastatic androgen receptor positive triple negative breast cancer. The participants need to be progressive after at least 1 prior cytostatic regimen in advanced setting. The participants will be treated with bicalutamide and abemaciclib. Bicalutamide works against the androgen receptor and abemaciclib stops the cell cycle. The investigators will look into if this combination can help patients with androgen receptor positive triple negative breast cancer. The investigators will also look into if this is a safe combination.

A Study to Investigate Long-term Safety and Tolerability of Tolebrutinib in Participants With Multiple Sclerosis.

Participants with relapsing MS from the Phase 2b LTS16004 parent study will continue open-label (OL) tolebrutinib. All participants from the Phase 3 parent studies (EFC16033, EFC16034, EFC16645, and EFC16035) will learn which treatment they received in the parent study: - If from one of the Phase 3 relapsing MS studies and on teriflunomide, an accelerated elimination procedure or a 3-month washout period is required prior to starting OL tolebrutinib. If on teriflunomide, and benefiting and recommended by the Investigator, the participant may opt to continue teriflunomide outside of the LTS17043 study, if clinically appropriate. If on tolebrutinib, the participant will continue tolebrutinib. - All participants from one of the Phase 3 progressive MS studies will start OL tolebrutinib. - If a participant already started OL tolebrutinib in the Phase 3 parent study this will be continued. - RMS participants who are not eligible for OL tolebrutinib per Health Authority and/or ethics committee decisions on the study conduct (ie, partial hold on initiation of tolebrutinib) will continue their parent study treatment assignment as per their randomization from the parent study. The treatment duration per participant will be approximately 3 years of OL tolebrutinib.

Bacteriophage Therapy for Difficult-to-treat Infections: the Implementation of a Multidisciplinary Phage Task Force

Patients with difficult-to-treat musculoskeletal infections, chronic rhinosinusitis, sepsis, pulmonary infections associated with cystic fibrosis or bronchiectasis, or hidradenitis suppurativa, for whom no standard (curative) treatment options are available, are eligible for phage therapy. Patient eligibility is evaluated by the Coordination group for Bacteriophage therapy Leuven. If phages are available against the isolated bacterial species and the patient is found eligible for phage therapy, a phagogram is performed. Solely based on the results of the phagogram, the patient is either included in the phage treated or control group (standard (non-curative) treatment). In both cases, data is collected using REDCap.

A Phase III Randomised Study to Evaluate Dato-DXd and Durvalumab for Neoadjuvant/Adjuvant Treatment of Triple-Negative or Hormone Receptor-low/HER2-negative Breast Cancer

The primary objectives of the study are to demonstrate superiority of neoadjuvant Dato-DXd plus durvalumab followed by adjuvant durvalumab with or without chemotherapy relative to neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab with or without chemotherapy in participants with previously untreated TNBC or hormone receptor low/HER2-negative breast cancer, by central assessment of pCR and/or to demonstrate superiority of neoadjuvant Dato-DXd plus durvalumab followed by adjuvant durvalumab with or without chemotherapy relative to neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab with or without chemotherapy in participants with previously untreated TNBC or hormone receptor-low/HER2-negative breast cancer, by investigator assessment of EFS

Rilvegostomig + Chemotherapy as Adjuvant Therapy for Biliary Tract Cancer After Resection (ARTEMIDE-Biliary01)

This is a Phase III, randomized, double-blind, placebo-controlled, multicenter, global study to assess the efficacy and tolerability of rilvegostomig compared to placebo in combination with investigator's choice of chemotherapy (capecitabine, S-1(tegafur/ gimeracil/ oteracil) or gemcitabine/cisplatin) as adjuvant treatment in participants with BTC after resection with curative intent. This study will be conducted in patients with BTC who are at risk of recurrence after resection with curative intent.
