Here are two examples of nominalized サ変 verbs.

> あす必ず任務を達成 **すること** を約束する。
>
> 彼らは私たちがこの薬を試用 **すること** を認めた。

Given that the stems of サ変 verbs are nouns, is it okay to just drop the する
(and こと) in the above sentences? What I am worried about is that 達成する and 試用する
above carry objects indicated by を, namely 任務を and 薬を, respectively, and so I
am not sure whether the following sentences are valid or problematic.

> あす必ず任務 **を達成** を約束する。
>
> 彼らは私たちがこの薬 **を試用** を認めた。

nominalization
Nominalizing a sentence ending in サ変 verbs
Those are not valid sentences.

Removing する from a [N + する] verb has impacts on not only its object but also
its subject and adverbs that modify it.

Since the first sentence has no subject, the object 任務 gets marked with の to
form the noun phrase 任務の達成. あす and 必ず pose some challenge. If left as they
are, they would modify the only verb left in the sentence, namely 約束する. If
they are to modify 達成, they would have to be converted into noun-modifying
forms. あす could be simply changed to あすの. However, since 必ず has no
corresponding adjective form, it would have to be substituted with an
adjective with a similar meaning, such as 確実な.

> あすの確実な任務の達成を約束する。

The second sentence has both the subject (私たち) and the object (この薬). While not
totally unacceptable, 私たちのこの薬の試用 would sound a bit awkward. This problem could
be avoided by marking 私たち with に so it collocates with 認める.

> 彼らは私たちにこの薬の試用を認めた。
