IIEXECUTIVE SUMMARY
II.1Problem statement
Not applicable for generic application.
II.2About the product
Pantoprazole is a substituted benzimidazole which inhibits the secretion of hydrochloric acid in the stomach by specific blockade of the proton pumps of the parietal cells.
Pantoprazole is converted to its active form in the acidic environment in the parietal cells where it inhibits the H+, K+-ATPase enzyme, i. e. the final stage in the production of hydrochloric acid in the stomach. The inhibition is dose-dependent and affects both basal and stimulated acid secretion. In most patients, freedom from symptoms is achieved within 2 weeks. As with other proton pump inhibitors and H2 receptor inhibitors, treatment with pantoprazole reduces acidity in the stomach and thereby increases gastrin in proportion to the reduction in acidity. The increase in gastrin is reversible. Since pantoprazole binds to the enzyme distal to the cell receptor level, it can inhibit hydrochloric acid secretion independently of stimulation by other substances (acetylcholine, histamine, gastrin). The effect is the same whether the product is given orally or intravenously.
The active substance pantoprazole is indicated for disorders related to gastric acid hypersecretion including peptic ulcers, gastroesophageal reflux disease, NSAID related ulceration, Zollinger–Ellison Syndrome and Helicobacter pylori infection.

IIISCIENTIFIC OVERVIEW AND DISCUSSION
III.1 Quality aspects
Drug substance
The active substance pantoprazole sodium sesquihydrate is described in Ph.Eur. Two manufacturers are declared for the drug substance:
One manufacturer is provided a Certificate of Suitability for pantoprazole sodium sesquihydrate.
The quality of the active substance is controlled by the current version of the Ph. Eur. monograph for pantoprazole sodium sesquihydrate and it is supplemented by the tests mentioned below, based on the analytical procedure(s) given in Annex to the CEP:
The documentation of other manufacturer on the active substance pantoprazole sodium sesquihydrate is presented as an Active Substance Master File (ASMF).
All the issues raised with regard the ASMF have been properly solved. The applied route of synthesis and the used starting materials are considered appropriate. The general properties and the elucidation of structure are well discussed.
The information provided for the control of potential impurities is considered sufficient. The control tests and specifications for drug substance product are adequately drawn up. The
analytical methods have been sufficiently validated. Batch analysis data demonstrating compliance with the proposed drug substance specification of the Applicant were provided for ten production scale batches of the drug substance.
Drug Product
The drug product corresponds to gastro-resistant tablets available in the strengths of 20 mg and 40 mg pantoprazole, corresponding to 22.557 and 45.113 mg pantoprazole sodium sesquihydrate, respectively. Proposed packaging materials is cold form blister pack comprises of aluminium foil/ polyamide/polyvinyl chloride film on one side and aluminium foil on the other side with heat seal coating.
The development of the product has been described, the choice of excipients is justified and their functions explained. Manufacturing process development was adequately explained.
Comparative dissolution profiles of test and reference product of the bioequivalence study as well as of test product of the bioequivalence study and batches of both strengths of pantoprazole gastro-resistant tablets were provided with the respective similarity factors. Similarity of dissolution profiles
Pantobax 20 mg, 40 mg gastro-resistant tablets, LT/H/0105/001-002/DCDay 210 FAR-0Page 6/18
was shown acceptably. Similarity of dissolution profiles was proved for the drug product applied for in relation to reference medicinal products of different EU member states, too.
The information provided with regard to manufacturing process of the medicinal product is considered adequate.
The proposed specifications at release and shelf life are considered acceptable. The analytical methods are described and validated.
The conditions used in the stability studies are according to the ICH guideline. The proposed shelf-life of 36 months without any special labelled storage conditions is considered justified by stability data provided.
III.2 Non clinical aspects
Pharmacodynamis, pharmacokinetic and toxicological properties of pantoprazole are well known. As pantoprazole is a widely used, well-known actives substance, the applicant has not provided additional studies and further studies are not required. Overview based on literature review is, thus, appropriate.
Environmental Risk Assessment (ERA)
Since pantoprazole is intended for generic substitution, this will not lead to an increased exposure to the environment. An environmental risk assessment is therefore not deemed necessary.
Conclusions
There are no objections to approval Pantobax 20 mg gastro-resistant tablets and Pantobax 40 mg gastro-resistant tablets from a non-clinical point of view.
III.3 Clinical aspects
To support the application, the applicant has carried out a 3 single dose bioequivalence studies:
study BE-038-PANT-2006: 40 mg tablet under fasting conditions study 111_PANTO_06: 40 mg tablet under fed conditions
study BE-155-PANT-2008: 20 mg tablet under fasting conditions
The studies were performed in healthy volunteers. The GCP/GLP aspects of the clinical phases of the studies are sufficiently documented. Quality assurance documents were provided.
The study BE-038-PANT-2006 was an open label, randomized, two-treatment, two-sequence, four-period, cross-over single-dose bioequivalence study of pantoprazole under fasting conditions. Sixty healthy male subjects, aged 18 - 42 years, were included in this study. A single oral dose of Test or Reference product (one tablet, containing 40 mg Pantoprazole as pantoprazole sodium sesquihydrate) was administered in each period. Each treatment was separated by a washout period of 7 days. In accordance with the study protocol, bioequivalence was accepted if the 90% confidence intervals of the test to reference product of ln-transformed AUC and Cmax were within the acceptance range of 80% to 125%. The 90% CI ranges for AUC0-t was 91.96 – 97.78%. For AUC0-∞ was 91.98 – 97.74%, for Cmax the 90% CI range was 90.98 – 100.05%.
The study 111_PANTO_06 was an open label, randomized, two-treatment, two-period, two-sequence, cross-over, single-dose, bioequivalence study of 40 mg pantoprazole under fed conditions. Forty healthy male subjects, aged 19 - 43 years, were included in this study and 38 subjects completed the study. A single oral dose of Test or Reference product (one tablet, containing 40 mg Pantoprazole as pantoprazole sodium sesquihydrate) was administered. Subjects received the alternate ‘treatment’ in the subsequent periods, in such a way that each subject received both the products by the end of the study. The Test or Reference product was administered with 240 mL of drinking water, 30 minutes after start of high-fat, high-calorie breakfest under supervision of trained study personal. Each treatment was separated by a washout period of 6 days. In accordance with the study protocol, bioequivalence was accepted if the 90% confidence intervals of the test to reference

product of ln-transformed AUC and Cmax were within the acceptance range of 80% to 125%. The 90% CI ranges for AUC0-t was 87,36 – 106,62%. For AUC0-∞ was 89,04 – 110,53%, for Cmax the 90% CI range was 85,02 – 118,21%.
The study BE-155-PANT-2008 was an open label, randomized, two-treatment, two-sequence, two-period, cross-over single-dose bioequivalence study of pantoprazole 20 mg tablets in forty healthy adult subjects under fasting conditions. Forty healthy male subjects, aged 18 - 42 years, were included in this study. A single oral dose of Test or Reference product (one tablet, containing 20 mg Pantoprazole as pantoprazole sodium sesquihydrate) was administered. Subjects received the alternate ‘treatment’ in the subsequent periods, in such a way that each subject received both the products by the end of the study. In accordance with the study protocol, bioequivalence was accepted if the 90% confidence intervals of the test to reference product of ln-transformed AUC and Cmax were within the acceptance range of 80% to 125%. The 90% CI ranges for AUC0-t was 97.71 – 105.27 %. For AUC0-∞ was 97.83 – 105.96 %), for Cmax the 90% CI range was 91.06 – 103.78 %.

Ši generinė paraiška buvo pateikta pagal direktyvos 2001/83/EB 10 str. 1d. ir pareiškėjas klinikiniais tyrimais įrodė, kad Pantobax 20 mg ir 40 mg skrandyje neirios tabletės yra iš esmės panašios į referencinį vaistinį preparatą Protium 20 ir 40 mg gastro-resistant tablets, RTT Altana Pharma AG, Vokietija.
Pantoprazolas yra pakeistas benzimidazolas, kuris, specifiškai blokuoja parietalinių skrandžio gleivinės ląstelių protonų siurblį, todėl slopina vandenilio chlorido rūgšties sekreciją skrandyje. Rūgščioje parietalinių ląstelių terpėje pantoprazolas virsta aktyvia forma cikliniu sulfenamidu, kuris slopina fermentą H+, K+-ATF-azę, t. y. galutinį vandenilio chlorido rūgšties gamybos skrandyje etapą.
Slopinimas priklauso nuo dozės dydžio, poveikis pasireiškia bazinei ir stimuliacijos sukeltai rūgšties sekrecijai. Daugumai pacientų rėmuo ir rūgšties refliukso simptomai išnyksta per savaitę. Pantoprazolas mažina rūgštingumą skrandyje, todėl proporcingai rūgštingumo sumažėjimui padaugėja gastrino. Gastrino kiekio padidėjimas yra laikinas. Kadangi pantoprazolas jungiasi prie fermento, esančio distaliau nuo receptoriaus, vandenilio chlorido rūgšties sekreciją jis slopina nepriklausomai nuo kitų medžiagų (acetilcholino, histamino, gastrino) sukeliamo stimuliavimo. Išgerto ar į veną injekuoto pantoprazolo poveikis nesiskiria.
Naujų ikiklinikinių tyrimų duomenų apie pantoprazolą pareiškėjas nepateikė, nes referencinis vaistinis produktas, į kurį referuoja ši „generinė“ paraiška rinkoje yra daugiau nei 10 metų. Išskyrus biologinio ekvivalentiškumo tyrimus, kitų klinikinių tyrimų atlikta nebuvo, atsižvelgiant į „generinės“ paraiškos reikalavimus. Bioekvivalentiškumo tyrimai buvo atlikti pagal geros klinikinės praktikos reikalavimus.
RMS ir CMS nusprendė, kad paraiška yra priimtina ir užbaigė šią rinkodaros teisės suteikimo procedūrą (210 dieną) 2012-05-23. Po nacionalinės fazės Lietuvoje rinkodaros teisė buvo suteikta
2013-07-31.
