About This Presentation

Description : Check out this medical PowerPoint presentation titled "IMMUNOTHERAPY" by Vanesa Gregorc MD.

This medical PowerPoint presentation talks about immunotherapy. Immunotherapy is a type of medical treatment that involves using the bodys immune system to fight diseases such as cancer, infections, and autoimmune disorders. This approach works by boosting or modifying the bodys natural defense mechanisms to help it identify and attack harmful cells.

IMMUNOTHERAPY Vanesa Gregorc MD IRCCS San Raffaele, Milano
Slide 2-

LUNG CANCER AS AN IMMUNOLOGIC-MEDIATED DISEASE AND TARGET FOR IMMUNOTHERAPY Although many immunotherapies are being investigated in NSCLC, currently none have been FDA approved, as vaccines and other immune-modulators have yet to demonstrate considerable improvements inOS in phase III clinical trials
Slide 3-

NOVEL ASPECTS Immune-related response criteria Endpoints The immune-related toxicities All differ considerably from conventional cytotoxic agents and targeted therapies
Slide 4-

RESPONSE EVALUATION FOR IMMUNOTHERAPY Permissive not restrictive RECIST/mWHO modified by immunological criteria First radiological examination the most critical (pseudo-progressions) irResponders with new lesions also but decrease in baseline lesions PD should be confirmed after 4 w Wolchok JD, et al Clin Cancer Res 2009; 15:7412-7420.

PROGRAMMED DEATH-1 IMMUNE CHECKPONT (PD-1) PD-1 (cell receptor) is overexpressed on NSCLC-infiltrating T cells and these are functionally exhausted cells Ligands: PDL-1 and PDL-2 (tumor cell /APC) Higher tumoral PDL-1 expression correlates with decreased OS RATIONALE Blocking the PD-1 or PDL-1 pathway would restore/promote the function of chronically exhausted tumor-specific T cells and decrease tumor-induced immune suppression Zhang Y et al. Cell Mol Immunol. 2010;7:389- 395.

Butts ASCO2013 L-BLP25 MUC1 is a mucinous glycoprotein that is overexpressed and aberrantly glycosylated in many human malignancies. BLP25 is a synthetic, liposomal cancer vaccine that targets the extracellular tandem repeat sequences of the MUC1 tumour-associated antigen.

STOP TRIAL stage III/IV in DC after 1° line belagenpumatucel-L Giaccone et al.ESMO 2013 Primary endpoint: OS Other endpoints: PFS, RR, QoL, CNS metastases, safety Belagenpumatucel-L(Lucanix®) uses genetically modified whole tumour cells to stimulate the patient's own immune system to attack the tumour. It is comprised of 4 transforming growth factor (TGF)-ß2 antisense gene-modified, irradiated, allogeneic NSCLC cell lines.

STOP TRIAL did not meet predefined end point-OS BUT: Significantly prolonged overall survival in patients who began belagenpumatucel-L within 12 weeks of the completion of front-line chemotherapy or RT in Sq and Non-Sq

conclusions Immunotherapy has promising anti-tumor activity in NSCLC and an unique set of side effects consistent with the immune mechanism of action Patient selection (biomarker) might be the key to further development as a single agent and in combination with other therapies Phase III trials are ongoing in order to make immunotherapy a reality for the treatment of NSCLC
