The active substance is tasonermin.
Tasonermin did not cross the placenta or pass into necrotic tumour.
Each vial contains 1 mg tasonermin.
Each vial contains 1 mg tasonermin, corresponding to 3.0-6.0 x 107 IU.
It contains the active substance tasonermin.
Tasonermin does not cross the intact blood-brain barrier to a significant extent in mice.
No late detrimental effects of tasonermin were seen.
The active substance in Beromun, tasonermin, is a copy of the human protein tumour necrosis factor alfa-1a(TNF α).
The systemic pharmacokinetic information on tasonermin is sparse.
Beromun contains the active substance tasonermin(tumor necrosis factor alfa-1a), produced by recombinant DNA technology.
There is no evidence that any of these agents counteracts the pharmacodynamic effects of tasonermin.
Therefore, whenever there is significant systemic leakage of tasonermin, serious undesirable effects are to be expected.
This is to ensure optimal haemodynamic conditions and ensure a high urinary output,especially after the perfusion, to allow for rapid clearance of any residual tasonermin.
The toxicological profile of tasonermin has been investigated in preclinical studies using mice, rats, rabbits, dogs and monkeys.
Beromun should not be used in people who may be hypersensitive(allergic) to tasonermin or any of the other ingredients.
Direct inhibition of tumour cell proliferation: Tasonermin is cytotoxic or cytostatic in vitro for a variety of tumour cell lines of different histogenesis.
In the Rhesus monkey, whole body radiography following administration of radiolabelled tasonermin indicated no specific distribution pattern.
The active substance in Beromun, tasonermin, is produced by a method known as‘ recombinant DNA technology': it is made by bacteria that have received a gene(DNA), which makes them able to produce TNFα.
Clinical data however indicate that the overall incidence of adverse events is increased if patients are simultaneously exposed to tasonermin and interferon-gamma.
Further, animals that reject experimental tumours following tasonermin treatment may develop specific immunity for this tumour cell type.
Tasonermin has been shown to be active in the classic assay for tumour necrosis factor, producing haemorrhagic necrosis of tumour nodules in murine syngeneic and human xenogeneic tumour systems after local or systemic injection.
In the Rhesus monkey, pharmacokinetic studies following intravenous injection of tasonermin indicated a non-specific, non-saturable excretion via glomerular filtration in the kidney.
The systemic application of tasonermin is limited by its toxic effects, the effective dose predicted from preclinical studies being substantially higher than the observed human maximum tolerated dose.
Under conditions of greater than 2% systemic leakage(observed in 13 of 51 patients)maximum systemic concentrations of tasonermin were still at least ten times lower than in the perfusion circuit.
Further, in addition to its direct effects, tasonermin modulates immune responses by inducing production of cytokines as well as low molecular weight mediators(prostaglandins, platelet activating factor).
Several lines of evidence suggest that these immunomodulatory activities are of relevance for the antitumour effects;e.g. the antitumour activities of tasonermin are much less pronounced in immunodeficient animals.
Perfusate samples of several ILPs showed plateau levels of tasonermin(as measured by ELISA) up to 100 minutes after start of perfusion, with no decay attributable to degradation.
Tasonermin affects the morphology and reduces proliferation of endothelial cells and modifies expression of specific cell surface and secretory proteins(including adhesion molecules and proteins modulating coagulation, interleukins and haematopoietic growth factors).
Combinations with cardiotoxic substances(e.g. anthracyclines)should be avoided because it is possible that tasonermin could enhance cardiotoxicity, as has been observed in preclinical 13-week toxicological investigations.
The addition of interferon-gamma to the tasonermin perfusate seems not to be associated with significant increases in endogenous production of tasonermin or other inflammatory cytokines as shown in patients with severe trauma.
