Changing University name, thesis title e.a. for abstract in different language - latex

Question

I need to write two different abstracts in my thesis in german and in english. The German one works fine and by using the \begin{otherlanguage} command, the abstract name itself changes to english. But furthermore I need to use an english tilte, university name, faculty name and company name for the second abstract. I tried using \renewcommand but it does not change the title in the output file, which is still german.
I found packages for multiple titles (\titling), but that is not working for the university name and so on.
Thank you in advance
\documentclass[11pt, english, ngerman,]{MastersDoctoralThesis}
\thesistitle{Title in German}
\university{University Title in German}
\begin{document}
\begin{abstract}
\addchaptertocentry{\abstractname}
German German German
\end{abstract}
\begin{otherlanguage}{english}
\renewcommand{\thesistitle}{Title in English}
\renewcommand{\university}{University Title in English}
\begin{abstract}
English English English
\end{abstract}
\end{otherlanguage}

I do not have, neither know the package MastersDoctoralThesis.
If it includes the babel package, you can use iflang to test the active language.
\documentclass[11pt]{article}
\usepackage{iflang}
\usepackage[german]{babel}
%\usepackage[english]{babel}
\begin{document}
\IfLanguageName{german}{
German German German
}{
English English English
}
\end{document}
If your document class does not include the babel language, you can do something similar by defining a macro and testing its value with the ifthen package.
\documentclass[11pt]{article}
\usepackage{ifthen}
\def\mylanguage{german}
\begin{document}
\ifthenelse{\equal{\mylanguage}{german}}{
German German German
}{
English English English
}
\end{document}
