Content of the pack and additional information
1.
What CALGEVAX is and what it is used for
CALGEVAX is BCG specially designed for cancer immunotherapy.
• Intravesically:
- for prophylaxis of the recurrences of the superficial tumors of the bladder after transurethral
resection;
- for treatment of carcinoma in situ of the bladder.
• Percutaneously:
- in the treatment of malignant melanoma;
- for nonspecific adjuvant immunostimulating therapy of other newly emerged malignant growths
(lung, breast cancer, acute leukemia, lymphosarcoma or osteosarcoma).
2.
What should be known before CALGEVAX is given
Do not administer CALGEVAX if:
-
there is allergy to the active substance or any of the other ingredients of this medicine (listed in
item 6).
Warnings and preventive measures
You should consult your doctor or pharmacyst before using CALGEVAX.
CALGEVAX IS NOT ADMINISTERED:
● in case of patients with immunosuppression;
2
● in case of patients with inherent or acquired immune insufficiency caused by a disease or an
antitumor therapy;
● in case of HIV-positive persons and patients on immunosuppression doses of steroids or other
immunosuppresants;
● in febrile conditions;
● in case of infection of the urinary tracts or massive haematuria, as well as in a parallel anti-microbe
therapy;
• in active tuberculosis; a positive tuberculin Mantoux test is a contraindication only in case of
certified active tuberculosis infection;
• In case of ongoing or previous systemic BCG reaction (i.e. a systemic granulomatous disease,
which can be revealed after the administration of BCG; it is determined on the basis of the
following symptoms: fever ≥39.5°С for ≥12 hours; fever ≥38.5°С for ≥48 hours, pneumonitis,
hepatitis or another organ disfunction outside the urinary-genital tract involving a granulomatous
inflammation, which is established through biopsy, or the classical symptoms of sepsis).
NECESSARY PRECAUTIONS FOR USE:
• Patients, who have had the medicine administered intravesically, should maintain adequate
hydration.
• The intravesical administration of CALGEVAX may result in local inflammation of the urinary
bladder, accompanied by haematuria, dysuria, pollakiuria and flu-like symptoms. Patients with a
small capacity of the bladder are exposed to a higher risk of severe local reactions.
• In case of a doubt about a systemic BCG infection after the administration of CALGEVAX, which
may proceed with a fever above 390С, persisting temperature of over 38 0С or fatigue, a prompt
antituberculosis treatment is carried out after consulting a specialist.
• CALGEVAX contains live bacteria and should be treated as infectious material. Persons with
immunosuppression should not handle CALGEVAX.
• The catheterization of the bladder should be performed carefully avoiding traumatization of the
mucous membrane. If the doctor, performing the treatment, decides that the catheterization is
traumatic (for example, involves bleeding), the administration of the product should be postponed
by at least 14 days.
• In case of serious overall adverse reactions, the intervals between the separate administrations are
extended. The treatment with CALGEVAX may be terminated at the discretion of the doctor,
performing the treatment. Antituberculosis treatment is recommended in case of disseminated
BCG infection.
Children and adolescents
CALGEVAX is not recommended for children due to the absence of sufficient data about the safety
and efficiency of the product regarding children.
Other medicines and CALGEVAX:
You should inform your doctor or pharmacyst if you have taken or can possibly take other medicines.
Taking of CALGEVAX may result in an increased sensitivity towards tuberculin, which would
complicate the interpretation of the skin reaction to tuberculin in a future testing for suspected
mycobacterial infections. In this context, it is recommended to determine the patient’s reaction to
tuberculin prior to the immunotherapy with CALGEVAX.

Pregnancy, lactation and fertility
Do not take this medicine without first consulting your doctor, if you are pregnant or breast-feeding,
think that you might be pregnant or plan to become pregnant.
The risk/benefit balance is assessed carefully, when the medicinal product should be administered
during pregnancy and lactation due to the absence of clinical data about its administration in these
cases. It is known that a lactating woman with a systemic BCG infection may infect her child.
Driving and using machines
The effect of CALGEVAX on the ability to drive and operate machinery has not been studied.
3.
How to administer CALGEVAX
You should take this medicine as described in this leaflet or as your doctor of pharmacyst has told you.
If you are uncertain about something, ask your doctor or pharmacyst.
INTRAVESICAL ADMINISTRATION:
CALGEVAX is administered at least 14 days after the performance of a biopsy, transurethral resection
or traumatic catheterization. The application of CALGEVAX should be done using aseptic equipment
and under the control of a urologist, having experience in the administration of the product. Three or
four ampoules of the product are used for each intravesical instillation at the discretion of the urologist
performing the treatment. The content of each ampoule is reconstituted into 1 ml of sterile saline (a
solution of sodium chloride with concentration of 9 g/l), carefully shaken until obtaining a
homogeneous suspension. The mixture is drawn by syringe and then returned to the ampoule three
times in order to ensure thorough mixing, which minimizes the clumping of the mycobacteria. The
content of the ampoules is transferred in a syringe of 50 ml. A supplementary volume of sterile saline
is added bringing the total volume to 50 ml. Light reduces considerably the efficiency of
CALGEVAX. Therefore, exposure to direct daylight should be avoided both before and after
preparing the suspension. The suspension should be used immediately.
After empting the bladder, the reconstituted CALGEVAX is instilled slowly into the bladder through
urethral catheter. The product remains in the urinary bladder in the course of two hours. While the
CALGEVAX is being retained in the bladder, every 15 minutes the patient alternates the following
positions: semi-left turning, semi-right turning, left side, right side.
The standard scheme of administration includes one intravesical instillation once a week in the course
of six weeks (inducing therapy). The maintenance therapy is determined on a case-by-case basis. The
following schemes can be used: monthly administration in the course of minimum 6-12 months or
three weekly instillations at the 3rd, 6th, 12th, 18th, 24th, 30th and 36th month of the date of the first
instillation.
PERCUTANEOUS ADMINISTRATION:
Ten horizontal and ten vertical lines are made by the syringe needle on an area of 5/5 сm. The
scarification should tear only the epidermal layer without causing extensive bleeding.
A multipuncture apparatus can also be used to regulate the depth of the scarification.
The scarification spot is treated by the following 0.5-ml suspension: the content of one ampoule is
mixed with 0.5 ml of sterile saline to obtain concentration of 75 mg/ml. One ampoule is used for one
scarification. Prior to the procedure, the area should be treated with acetone after which its full
4
evaporation should be awaited. A new area is chosen for every following scarification. The frequency
and duration of administration are determined by the doctor, performing the treatment.
4. Possible undesirable reactions:
This medicine, like most other medicines, may cause adverse reaction, although this does not apply to
all people.

професии: полу-лявата струговане, полу-надясно по струговане, лявата страна, дясната страна.
Стандартната схема на приложение включва една интравезикално вливане веднъж седмично в течение
на шест седмици (индуциране на лечение). Поддържащата терапия се определя въз основа на всеки отделен случай. Най-
могат да бъдат използвани следните схеми: месечно в продължение на 6-12 месеца или минимални
три седмични вливания на 3-ти, 6-ти, 12-ти, 18-ти, 24-ти, 30-ти и 36-ти месец от датата на първото
вливане.
Перкутанно приложение:
Десет хоризонтална и десет вертикални линии са направени от иглата на спринцовката върху площ от 5/5 см. Най-
обезобразяване трябва да откъсне само на епидермалния слой, без да причинява значително кървене.
Устройство за multipuncture може да се използва за регулиране на дълбочината на обезобразяване.
място за обезобразяване се лекува чрез следния 0,5 мл суспензия: съдържанието на една ампула е
се смесва с 0,5 мл стерилен физиологичен разтвор за да се получи концентрация от 75 мг / мл. Една ампула се използва за един
обезобразяване. Преди процедурата, площта трябва да бъдат лекувани с ацетон, след което неговото пълно

ANTITUMOR AGINT BASED ON BCG VACCINE, METHOD OF ITS PREPARATION AND USE
Technical area
The invention relates to an agent with antitumor activity on the basis of BCG vaccine, a method for its preparation and its application for treatment of patients diagnosed with oncological diseases.
Background of the invention
The results of a number of scientific studies published over the past several years show that the antitumor properties of the Mycobacteriaceae family are due to active agents it contains or produces.
Thus, US patent 6, 274, 356 describes a carbohydrate complex, in essence representing a complex of polysaccharides, extracted from Mycobacterium vaccae, which shows high antitumor activity in the treatment of different oncological diseases. The method of preparation of the carbohydrate complex has also been described as a series of actions, involving obtaining precipitates and dialisates by extraction and purification.
Summary of the invention
The problem of the present invention is obtaining of an agent with antitumor activity based on the BCG vaccine, which gives maximum opportunity for the action of the antitumor factor of the BCG vaccine in order to terminate the rapid and uncontrolled proliferation of tumor cells in an environment of reduced toxicity and blocking of the inhibitive effect of tumor cells on normal cells in the body as well the method of obtaining of BCG-based agent with antitumor activity and its use. According to the invention this problem was solved with a BCG vaccine based agent (BCG with Mycobacterium bovis as active substance, controlled by the manufacturer in compliance with WHO requirements regarding the physical, chemical and biological properties of the bacterial strains and of the final product), which has a powerful inhibitive effect on tumor cells and has demonstrated no undesirable side effects.
The agent according to the invention is a mixture of two independent fractions the ratio between which may vary from 1 :0.01 to 0.01:1.
Fraction 1 named "Live BCG Bacteria" contains a standard BCG vaccine, diluted once by physiological solution or distilled water to a concentration from 100 to 10 μg/ml and secondly diluted by physiological solution from 10 to 0.001 μg/ml.
Our definition of standard BCG vaccine solution means 1 ampoule BCG vaccine containing 500 μg dry substance, diluted by 1 ml distilled water used as standard solvent.
Fraction 2 termed "BCG Vaccine Extract-filtrate" contains standard solution of BCG vaccine, diluted by 4-6 ml distilled water or 3-5 ml physiological solution.
Another object of the invention is a method for preparation of an agent with antitumor activity as per the invention. The essence of the method lies in obtaining two different fractions, respectively termed Fraction 1 - "Live BCG Bacteria" and Fraction 2 - "BCG Vaccine Extract-filtrate", which under specific processing conditions are mixed in a certain proportion.
Fraction 1 is made from a standard ampoule of 500 μg dry substance of BCG vaccine, the shelf-life (exp.date) of which must not have expired. Following the instructions the ampoule is diluted with standard solvent whilst strictly observing sterility rules in a sterile laboratory box, treated by UV lamps for 18-24 hours in advance. The resulting suspension is additionally diluted with physiological solution or distilled water up to a concentration of 100 to 10 μg/ml BCG. This suspension is diluted again until a concentration of 10 to 0.001 μg/ml is obtained (accepted as 10 provisional units according in line with the invention).
The content of live BCG bacteria is controlled by periodic microbiological samples on Leuvenstein-Jensen media for tuberculosis bacteria containing (in g/1 to double distilled water):
L-Aspargine 3.6
Monocalcium phosphate 2.4
Magnesium sulfate 0.24
Magnesium citrate 0.6
Potato flour 30.0
Malachite green 0.4
Glycerol 12.0 ml
Eggs 1 litre pH 7.2 ± 0.2 at 25 0C
Growth is controlled by the presence of specific colonies and specific morphology of the bacteria stained by Ziehl-Nielsen and examined under the microscope.
Fraction 2 is generated from standard BCG vaccine by adding 3 to 5ml physiological solution or 4 to 6 ml distilled water and ultrasound treatment for 8 to 12 minutes. The resulting suspension is left for a period of 2 to 60 days, preferably 2 to 20 days in a refrigerator at a temperature of 4-80C.
The content of live BCG bacteria is controlled by periodic microbiological samples on Leuvenstein-Jensen media for tuberculosis bacteria and the growth is demonstrated by the presence of specific colonies and specific morphology of the bacteria stained by Ziehl-Nielsen and examined under the microscope.
Between the 2nd and the 60th day the suspension is filtered though a sterile filter and the filtrate obtained is stored in a refrigerator at a temperature of 4 to 80C as initial extract-filtrate, which contains no live BCG bacteria.
Fraction 2 is a clear solution without any visible impurities, colour or odour. The chemical components of Fraction 2 include proteins, nucleoproteides, free aminoacids, polysaccharides, and small quantity of fats with the ratio between individual ingredients varying uncontrollably.
After the control examination aimed to establish the presence of live bacteria, the two fractions are mixed at Fraction 1 to Fraction 2 ratio from 0.01:1 to 1:0.01.
Yet another aspect of the invention is the use of the BCG-vaccine based agent with antitumor properties. The agent as per the invention is used for the treatment of all forms of malignancies in all stages of the disease.
The antitumor acting substance as per the invention is further applied for the treatment of various forms of cancer and specifically cancer of the throat, breast cancer, stomach cancer, liver cancer, cancer of the uterus, cancer of the colon, brain tumors, malignant melanoma, skin cancer and any other type of solid tumors, as well as of the metastases originating from various solid tumors in all systems of the human body.
Immediately after mixing the two fractions in the ratio determined as per the invention the BCG vaccine based agent with antitumor activity is injected intradermally to patients with cancer in a ratio from 0.1 to 0.2 ml.
For the purpose of sustained use the agent as per the invention is transferred to an ice bath and inserted into vacuum ampoules of 0.2 ml. Advantages of the Invention
As per the invention the main advantages of the invention of the areHT with antitumor effect are:
(1) powerful effect on tumor cells and termination of their rapid and uncontrolled proliferation;
(2) powerful effect on metastases, stopping their growth and leading to their regression and disappearance;
(3) blocking the repressing effect of tumor cells on normal cells in the system;
(4) low toxicity;
(5) possibly acts as cell growth factors, controlling the non- differentiated proliferation of cancer cells;
(6) simplified method of obtaining the agent.
