ELECTROMOTIVE DRUG ADMINISTRATION (EMDA)

by PHYSIONIZER MINI 30N2

EMDA – ElectroMotive Drug Administration is Imported in Thailand by Siam Trade development as License Holder of Physion SRL, Italy. Below its background and efficacy studies.

1.      PREMISE AND METHODOLOGY

PHYSIONIZER MINI 30N2 is a device used as carrier of drugs (commonly Mitomycin C) into the urothelium of the bladder affected by cancer.

PHYSION Srl, Italian Company, created the device Physionizer 30 (now called Physionizer Mini 30N2) in early 1990’s as drug administration vehicle for bladder cancer treatments. Principle is the enhancement of effects of Mitomycin C (MMC) and Bacillus Calmette-Guerin (BCG) in the treatment of high-risk non muscle-invasive bladder cancer through electrophoresis (EMDA)

Scope of the present file is to prove that the device Physionizer Mini 30N2 , used as vehicle for ElectroMotive Drug Administration, is

  • effective as treatment;
  • Safe for the patient;
  • Cost effective for the hospital.

In order to do this, we selected the main articles from the huge literature about the method (EMDA) performed by our device (Physionizer Mini 30N2).

We start back from 1996, when tests were performed on animals; then comparisons between BCG passive administration and through Physionizer Mini 30N2; then, results on large scale of treatments in different periods (2008, 2003, 2006, 2013, and latest dated 2018).

Scope of this summary is to show that the device Physionizer Mini 30N2 as vehicle for EMDA is safe and effective both in terms of benefice for the patient and in terms of costs for the hospital.

 2.      BACKGROUND

Bladder cancer is the 7th most common cancer worldwide.

Most bladder tumors (75-80 %) are non-muscle invasive cancer (Stage Ta, T1 and Tis).

Incidence rate are consistently lower in women than men, although sex differences varied greatly between countries.

There were almost 500.000 new cases in 2018.

The key challenge is to prevent recurrence and disease progression.

Physionizer Mini 30N2 has been designed to support doctors in this prevention by enhancing the effect of MMC and BCG treatments in the patients.

3.      PHYSIONIZER MINI 30N2 AND ELECTROMOTIVE DRUG ADMINISTRATION (EMDA)

Physionizer Mini 30N2 is a device that enables the Electromotive drug administration (EMDA), a non-invasive method of enhancing local drug penetration across the urothelium of the bladder.

Physionizer Mini 30N2 can be used for EMDA either prior to or after TURBT.

The purpose of Physionizer Mini 30N2 is to augment the effect of intravesical chemotherapy by creating an electric field across the bladder wall which increase urothelium’s permeability.

Physionizer Mini 30N2 is composed by 3 parts: a current generator, a catheter with an electrode inside, and two electrodes to apply externally to the apparatus.

Internal (catheter) and external electrodes create, when the current is emitted by the generator, an electric field that stimulates directional ionic and solute movement of intravesical fluid: drug is delivered to a greater tissue depth and results in greater concentration than is possible with passive diffusion.

Physionizer Mini 30N2 allows the operator to control the rate of drug administration, by varying the current intensity.

The applied electric current causes no biological damage to tissue and no chemical modification of drug.

3.1.    PROCEDURE

The procedure can be conducted on an outpatient basis. With the patient in a supine position electrodes are placed on the skin of the lower abdominal wall, an intravesical electrode contained in a specially designed catheter is then inserted into the bladder through the urethra, using an anesthetic gel as lubricant. A chemotherapeutic drug solution, usually mitomycin C (MMM-C) in bidistilled water, is instilled intravesical into the bladder through the catheter, as in standard intravesical chemotherapy.

The cutaneous and intravesical electrodes are connected to a generator that creates an electric field. Treatment last for 20 minutes. After the procedure the bladder is drained and the catheter is removed.

3.2.    PHARMACODINAMICS AND PHARMODYNAMICS

Mechanism of transport with Electromotive drug administration (EMDA) to the urinary bladder(1) (2)

Anesthetized adult mongrel dogs were studied(1). An intravesical anode was inserted through a Foley catheter into the urinary bladder. Two patch electrodes were positioned on the animals’ abdominal skin. Both skin and intravesical electrodes were attached to a direct current generator (Physionizer Mini 30N2). The bladder was then distended with an anionic blue dye (methylene blue). 15 mA pulsed direct current was applied for 40 minutes. After EMDA, the bladder was surgically removed and representative sections of full thickness bladder wall were immediately frozen in liquid nitrogen. Methylene blue was used to visually demonstrate Physionizer-enhanced anion penetration into bladder submucosa and muscularis.

 

This experimental model demonstrates significant submucosal and muscolaris methylene blue penetration in the presence of an electric field.

Same results were achieved with MMC-C in humans (2).

Physionizer Mini 30N2 significantly increases MMC-C concentration in all of the layers of the bladder wall (urothelium, lamina propria and superficial muscle layers): MMC-C concentration is 5-7 times increased compared to Passive Diffusion (PD); plasma levels remain well below toxic concentration.

4.      EVIDENCE-BASED TREATMENT

4.1.    Efficacy

Many authors have published  studies about Electromotive Drug Administration for non muscle invasive bladder cancer (3) (4) (5) (6) (7) (8) (9) (10) (11) (12) (13) (14) (15) (16)

Different clinical protocols have been studied to evaluate the impact of EMDA/MMC-C and compare the different modalities of treatment with EMDA/MMC-C. Most studied protocols have been performed with Physionizer Mini 30N2, others with devices with same specifications/functions.

Patients Primary endpoint Efficacy Resuts
108 patients with histologically proven multifocal carcinoma in situ (Tis) of the bladder (most had concurrent pT1 papillary transitional cell carcinoma) were randomly assigned to:

81 mg BCG (n=36);

or 40 mg electromotive mitomycin (intravesical electric current 20 mA for 30 min) (n=36),

or 40 mg passive transport mitomycin (n=36).

Patients in the 3 groups who had a complete response to the initial 6 weekly treatments underwent a further 10 monthly instillations. If cancer persisted at 3 months, a second 6 week course was given. If disease persisted at 6 months, there was a crossover to a 6-week second line course of BCG for patients in the 2 MMC groups and electromotive MMC for patients in the BCG group

The primary study end point was a complete response at 3 and 6 months following treatment.

 

The aim was to evaluate differences between responses to passive MMC, estimated at 33%, and to electromotive MMC, anticipated to be equivalent to that of a BCG response rate of 70%.

The complete response for

electromotive vs passive MMC at 3 and 6 months was 53% versus 28% (p < 0.036) and 98% versus 31% (p < 0.012).

For BCG the responses were 56% and 64%.

Median time to recurrence was 35 vs 19.5 months (p < 0.013) and for BCG it was 26 months.

RESULT:

EMDA increases bladder uptake of MMC, resulting in an improved response rate and an improved median time to recurrence

Patients Primary endpoint Efficay Results
212 patients with stage pT1 bladder cancer were randomly assigned to:

81 mg BCG infused over 120 min once a week for 6 weeks (n=105);

or to 81 mg BCG infused over 120 min once a week for 2 weeks, followed by 40 mg electromotive mitomycin (intravesical electric current 20 mA for 30 min) once a week as one cycle for three cycles (n=107).

Complete responders underwent

maintenance treatment

c) those assigned BCG alone had one infusion of BCG once/month for 10 months,

d) and those assigned BCG and mitomycin had 40 mg electromotive mitomycin once a month for 2 months, followed by 81 mg BCG once a month as one cycle for three cycles.

The primary endpoint was

either disease-free survival in patients without carcinoma in situ

or period from randomisation to first recurrencenoted by cystoscopy in patients with TCC

At a mean follow-up of 88 months 58% (62/107) of the patients in the BCG plus EMDA chemotherapy group were found to be _ disease-free compared with 42% (44/105) patients in the BCG alone group (p = 0.0012).

Patients in the BCG plus EMDA chemotherapy group had a lower overall mortality (22%; 23/107) (95% CI 13.5 to 29.5) compared with patients in the BCG alone group (32%; 34/105) (95% CI 23.4 to 41.4) at a mean follow-up of 88 months Hazard ratio 0.586 (p = 0.045).

RESULT:

Patients in sequential BCG-EMDA MMC group have a higher disease free interval (69 months ) and a lower recurrence than patients in BCG alone group ( 21 months )

Patients Primary endpoint Efficay Results
Of the 151 patients with high risk, non-muscle invasive bladder cancer treated between June 2009 and 2013, 44 underwent primary cystectomy and 107 received sequential bacillus Calmette-Guerin/electromotive drug administration of mitomycin C.

Disease was high grade Ta/T1 in 86 patients (80%), of whom 34 (32%) also had carcinoma in situ. A total of 19 patients (18%) had primary carcinoma in situ and 2 had recurrent large volume, low grade disease.

Primary outcomes were the recurrence rate at first, 1-year and 2-year cystoscopy.

Results were analyzed by intent to treat and by the actual treatment received.

Of the 107 patients receiving sequential bacillus Calmette-Guerin/EMDA of mitomycin C.  104 underwent first check cystoscopy, including 90 (87%) who were clear. Of the 90 complete responders 86 underwent 1-year cystoscopy, including 74 (86%) who were recurrence-free. Of these 74 patients, 71 underwent 2-year cystoscopy, of whom 66 (93%) remained recurrence-free.

RESULT:

This study confirms the excellent oncology efficacy of sequential BCG/Electromotive Drug Administration of MMC-C in cases of high-risk non muscle invasive bladder cancer

Patients Primary endpoint Efficay Results
124 patients were randomly assigned to receive TURBT alone,

126 to receive immediate post-TURBT PD Mitomycin C,

-and 124 to receive immediate pre-TURBT EMDA mitomycin C. Eligible participants had histologically proven primary pTa and pT1 urothelial carcinoma of the bladder.

The primary endpoint were:

recurrence rate

disease-free interval

for patients who were disease-free after treatment-ie, time from randomization to the first cystoscopy noting recurrence.

Patients assigned to receive EMDA mitomycin before TURBT had a lower rate of recurrence (44 [38%] of 117) than those assigned to receive PD mitomycin after TURBT (70 [59%] of 119) and TURBT alone (74 [64%] of 116; log-rank p<0-0001).

Patients assigned to receive EMDA mitomycin before TURBT also had a higher disease-free interval (52 months, IQR 32-184) than those assigned to receive PD mitomycin after TURBT (16 months, 12-168) and TURBT alone (12 months, 12-37; log rank p<0.0001)

 

RESULT:

Intravesical EMDA-MMC pre-Turbt reduces recurrence rates and enhances the disease free interval ( compared with intravesical MMC passive diffusion post-Turbt and Turbt alone ): exfoliated tumor cells that could implant were killed.

Patients in EMDA-MMC pre-Turbt group have an higher disease free interval (52 months ) and a lower time to recurrence ( 38 %)

6.      CONCLUSION

 

The Studies discussed above evidenced 3 different modalities of EMDA treatment with Physionizer Mini 30N2

  1. EMDA/MMC-C instillation with Physionizer Mini 30N2 in intermediate-risk(7) and high-risk(3) non muscle-invasive bladder cancer and for BCG failure patients(14)
  2. Sequential BCG – EMDA/MMC treatment through Physionizer Mini 30N2 for high-risk non muscle-invasive bladder cancer(4),(5),(10) and for BCG failure patients(13),(15)
  3. Pre-TURBT instillation of EMDA/MMC through Physionizer Mini 30N2 for intermediate-risk and high-risk non muscle invasive bladder cancer(6)

The results of these studies in intermediate and high risk NMIBC patients treated with Physionizer Mini 30N2, show significant short and long-term benefits with median disease-free interval longer and lower rate of recurrence.

An appropriate patients follow-up was done during two to twelve years post treatment administration.

Physionizer Mini 30N2 and EMDA treatment reduce medium term and long term costs (less cystectomies, less cystoscopies) and improve patients’ quality of life.

In addition, the 10-year cost-effectiveness randomized study(16) comparing sequential treatments with BCG/EMDA MMC-C instilled by Physionizer Mini 30N2 versus BCG alone, shows that the sequential therapy is a cost-effective treatment for patients with high risk non muscle invasive bladder cancer.
