TIL Therapy: Facts and Hopes.

After a positive phase III trial, it is evident that treatment with tumor-infiltrating lymphocytes (TIL) is a safe, feasible, and effective treatment modality for patients with metastatic melanoma. Further, the treatment is safe and feasible in diverse solid tumors, regardless of the histologic type. Still, TIL treatment has not obtained the regulatory approvals to be implemented on a larger scale.

Tumor-Infiltrating Lymphocyte Therapy or Ipilimumab in Advanced Melanoma.

Background: Immune checkpoint inhibitors and targeted therapies have dramatically improved outcomes in patients with advanced melanoma, but approximately half these patients will not have a durable benefit. Phase 1-2 trials of adoptive cell therapy with tumor-infiltrating lymphocytes (TILs) have shown promising responses, but data from phase 3 trials are lacking to determine the role of TILs in treating advanced melanoma.

Methods: In this phase 3, multicenter, open-label trial, we randomly assigned patients with unresectable stage IIIC or IV melanoma in a 1:1 ratio to receive TIL or anti-cytotoxic T-lymphocyte antigen 4 therapy (ipilimumab at 3 mg per kilogram of body weight).

Diabetic macular oedema treated with intravitreal anti-vascular endothelial growth factor - 2-4 years follow-up of visual acuity and retinal thickness in 566 patients following Danish national guidelines.

Purpose: To investigate long-term functional and anatomical outcomes, discontinuation patterns, drug switching and rates of nonimprovement in patients treated with ranibizumab pro re nata (PRN) regimen for diabetic macular oedema (DME) according to the Danish national guidelines.

Methods: Retrospective cohort study of 566 eyes in 566 patients with centre-involved DME who started intravitreal treatment with ranibizumab between January 2011 and December 2013 in the Greater Copenhagen region. Data were retrieved from a database and patient records between January 2011 and March 2016 and analysed using mixed-model statistics.
