Definitions

  • the invention relates to combination agents comprising cis-hydroxy-proline (CHP) and gemcitabine and the use of these agents in tumor prophylaxis and therapy.
  • CHP cis-hydroxy-proline
  • Tumors or cancer are localized increases in tissue volume and thus, in the broader sense, any localized swelling due to edema, acute or chronic inflammation, such as inflammation-related organ swellings, in the narrower sense tumors are new forms of tissue in the form of spontaneous, uninhibited, Autonomous and irreversible excess growth of the body's own tissue, which is usually associated with different degrees of loss of specific cell and tissue functions.
  • the consequences of this autonomous and irreversible excess growth lead to a considerable impairment of the organism, for example humans, and can lead to death.
  • Another difficulty in finding antitumor agents is that different derivatives or the original substance and its derivatives react and act differently, both in the animal model and also in humans.
  • various original substances are known which have no or only a slight antitumor effect, whereas their derivatives or derivatives can have a significant tumor-inhibiting but also a tumor-promoting effect.
  • Cis-hydroxy-proline has, for example, according to Klohe et al. (1985) did not find any properties that are necessary for an effective anti-tumor agent. Based on initial positive tests with this and other amino acids at the National Cancer Institute from 1933 to 1946, derivatives of proline and hydroxy-proline were synthesized in the following years to be used as a drug in cancer therapy (EP 02 23 850). Furthermore, because of the low activity of CHP (Klohe et al.), It has been proposed to use a combination of different CHP derivatives, since these should have a synergistic effect as a pharmaceutical agent in tumor treatment (US Pat. No. 6,066,665).
  • the described synergistic effects of the combination preparations proved to be only partially reproducible and, furthermore, the developed derivatives could only be used in very high concentrations - which are accompanied by side effects.
  • the object of the invention was therefore to provide a means and a method for cancer therapy based on CHP, which allow simple, safe and effective use.
  • a combination of CHP and gemcitabine has been found to have a high activity against tumor cells.
  • the invention therefore relates to the surprising teaching that a> compound, namely underivatized CHP, the antitumor properties of which have been described as insufficient in the prior art, in combination with the chemotherapeutic gemcitabine has an effect on cancer cells that is surprisingly higher than that of the individual compounds is.
  • CHP in the sense of the invention are ice isomers of 4-hydroxy-L-proline or its salts, without being CHP derivatives.
  • Gemcitabine in the sense of the invention is in particular gemcitabine hydrochloride, 2'-deoxy-2 ', 2'-di-fluorocytidine.
  • the combination agent in the sense of the invention can, for example, be such that CHP and gemcitabine are contained together in a solution or in a solid, such as a tablet.
  • the ratio of CHP and gemcitabine can vary freely. A ratio of CHP and gemcitabine in the range from 1: 10,000 to 10,000: 1 is preferred. Within this range, the ratio of CHP and gemcitabine can vary depending on the tumor or patient status.
  • the at least two components - CHP and gemcitabine - can also be introduced together into a solution or a solid in such a way that they are released with a time delay.
  • the combination agent in the sense of the invention can also consist of two separate solutions or two separate solids, one solution or one solid essentially gemcitabine and the other solution or other solid essentially CHP includes. It is possible that the two solutions or solids are associated with a common or with separate carriers. The two solutions and / or the two solids can be present, for example, in a capsule as a common carrier.
  • Such a formulation of the combination agent according to the invention is particularly advantageous if the CHP and the gemcitabine are to be administered with a time delay.
  • the organism is first brought into contact with CHP, for example by infusion or by oral administration, in order then to be brought into contact with the other constituent of the combination agent at a later time.
  • the combination agent it is also possible for the combination agent to be provided using customary pharmaceutical methods and processes in such a way that the organism is first brought into contact with gemcitabine and then with CHP. It is therefore preferred to sequentially bring the organism into contact with the components of the combination agent.
  • the time period between the administration of the two components of the combination agent according to the invention or the first release of CHP or gemcitabine depends on the age, gender, the overall constitution of the patient, the type of tumor or other parameters determined by the treating doctor, for example by preliminary tests can be.

This could also be shown when using combination agents in which the gereitabinin portion was completely replaced by oxoplatin or doxorubicin or another chemotherapeutic agent.
  • a further modification of the specificity of the combination agents was possible by using trans-hydroxy-proline instead of the ice form of the CHP.
