- Known human immunodeficiency virus (HIV) infection

- Positive for hepatitis C virus (HCV) infection at screening

- Significant cardiovascular disease (such as New York Heart Association Class II or greater cardiac disease, myocardial infarction, or cerebrovascular accident) within 3 months prior to initiation of study treatment, unstable arrhythmia (including active ventricular arrhythmia requiring medication), or unstable angina

- Major surgical procedure, other than for diagnosis, within 4 weeks prior to initiation of study treatment, or anticipation of need for a major surgical procedure during the study

- History of malignancy other than CUP within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death (e.g., 5-year OS rate > 90%), such as adequately treated carcinoma in situ of the cervix, non melanoma skin carcinoma, localized prostate cancer, ductal carcinoma in situ, or stage I uterine cancer

- Prior allogeneic stem cell or solid organ transplantation

- Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk from treatment complications

- Treatment with investigational therapy within 28 days prior to initiation of study treatment

- Known allergy or hypersensitivity to any component of the immunotherapy, including history of severe allergic anaphylactic reactions to chimeric or humanized antibodies or fusion proteins and to Chinese hamster ovary cell products or other recombinant human or humanized antibodies for nivolumab and ipilimumab.

- Subjects with an active, known or suspected autoimmune disease, including, but not limited to, myasthenia gravis, myositis, autoimmune hepatitis, myocarditis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, antiphospholipid antibody syndrome, Wegener granulomatosis, Sjögren syndrome, Guillain-Barré syndrome, or multiple sclerosis. Subjects with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.

- Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents, or other immuno-suppressive medications within 14 days of study treatment. Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents for adults, or > 0.25 mg/kg daily prednisone equivalent for adolescents are permitted, in the absence of active autoimmune disease.

- Subjects who received prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways

- All toxicities attributed to prior anti-cancer therapy other than alopecia and fatigue must have resolved to Grade 1 (NCI CTCAE version 5) or baseline before administration of study drug. Subjects with toxicities attributed to prior anti-cancer therapy which are not expected to resolve and result in long lasting sequelae, such as neuropathy after platinum based therapy, are permitted to enroll.

- Treatment with any chemotherapy, radiation therapy, biologics for cancer, or investigational therapy within 28 days of first administration of study treatment (subjects with prior cytotoxic or investigational products < 4 weeks prior to treatment initiation might be eligible after discussion between investigator and sponsor, if toxicities from the prior treatment have been resolved to Grade 1 (NCI CTCAE version 5).

- Subjects must not have received a live / attenuated vaccine within 30 days of first treatment.

- Pregnancy or breastfeeding, or intention of becoming pregnant during study treatment or within 5 months after the last dose of study treatment or intention of fathering a child within 7 months after the last dose of study treatment.

Brustkrebsmonat: Antihormonelle Therapie mit Nebenwirkungen

Etwa zwei Drittel aller bösartigen Brusttumore wachsen hormonabhängig. Weibliche Hormone wie das Östrogen lösen in den Tumorzellen einen Wachstumsreiz aus. Um das zu verhindern und das Rückfallrisiko zu senken, erhalten viele Brustkrebspatientinnen nach einer Operation zur Entfernung des Tumors über mehrere Jahre eine antihormonelle Therapie. Experten stufen die Begleiterscheinungen der Therapie zwar als weniger gravierend als bei einer Chemotherapie ein, viele...

Naturheilmittel oder neuer Trend der Bio-Welle? 94 Prozent der Deutschen können mit dem Begriff Biopharmazeutika nichts anfangen (1). Oftmals werden hinter dem Begriff Naturheilmittel vermutet. Dabei handelt es sich um Arzneimittel, die biotechnisch hergestellt oder aus gentechnisch veränderten Organismen gewonnen werden und mit dem Ziel der Bekämpfung einer Krankheit in die Vorgänge des Körpers eingreifen. Insulin ist ein bekanntes Beispiel. Wem das erklärt...

HPV-Impfung schützt vor Krebs
© pixelaway -

Krebsprävention ist eine zentrale Strategie im Kampf gegen Krebs. Zur Prävention zählen auch Impfungen, mit denen vielen Krebserkrankungen gezielt vorgebeugt werden kann. Beispiel: Humane Papillomviren (HPV), deren Hochrisiko-Typen für Gebärmutterhalskrebs und andere Krebserkrankungen verantwortlich sind. Doch es gibt eine wirksame und gut verträgliche Impfung, die vor der Infektion mit HPV schützt und der Entwicklung von Krebs vorbeugt. Wer sollte sich...
