3. 1. Observation :
Your firm failed to clean, maintain, and, as appropriate
for the nature of the drug, sanitize and/or sterilize
equipment and utensils at appropriate intervals to
prevent malfunctions or contamination that would alter
the safety, identity, strength, quality, or purity of the
drug product beyond the official or other established
requirements.
4. Observation 1(A):
• (b)(4) PDE-2095 had white residue on and around a
white interior gasket.
• Our investigator documented a gap in the gasket that
could allow processed materials to accumulate. The ends
of the gasket were also in poor condition.
5. Response:
The white residue on the white interior gasket of (b)(4)
was not the residue. Where they are the water drops after
cleaning , as we placed it for drying .
Where the gap in the gasket and poor condition of the
gasket of one particular (b)(4) was already kept under
maintenance before your inspections starts .
where the tag or label not kept by our personnel ,which
your investigator identifies as a defect.
6. Corrective action:

the personnel on proper labeling and tagging to the
equipment which are kept for under maintenance and
incident. And also planned a training program for
personnel who are involved in the cleaning activity.
7. Observation 1(B):
Our investigators observed multiple (b)(4), which you
identified as clean, containing colored residue and/or in
poor condition.
8. Response:
As the colored residue on the (b)(4) found in your
observation was sampled and analyzed to identify and
quantify any chemical and microbiological
contaminants.
And the results met microbial contaminants.
As our team investigated the root cause for the colored
residue on the cleaned (b)(4) .
It was finally found that the residue is due to improper
cleaning of that particular multiple (b)(4) by our
personnel ,which was only found in the block-5 and
block-6 of manufacturing area.
9. Corrective action:
By this observation our firm implementing proper
training plan to the personnel responsible for cleaning,
verifying equipment cleanliness, and maintaining
equipment.
which is capable of performing their assigned duties.
Include cleaning validation was done.
And also we are implementing self inspection program

failed to follow your written procedures regarding the
recall of failing product.
11. On July 8, 2016, you received a complaint that one
tablet in a bottle of 5 mg finasteride tablets, lot
FIN16002, was approximately double the thickness of
the others. You confirmed the defect after receiving the
complaint sample on July 27, 2016, but did not initiate a
product recall as directed by your own procedures until
investigators pointed out.
12. Response:
As our firm has an efficient quality system manual and
product recall procedure.

manufacturer of (b)(4) mg (b)(4) tablets for multiple
customers. In February 2017, you received a customer
complaint that lot (b)(4) failed dissolution testing.
15. Response :
We thoroughly investigate the batch failure of (b)(4) by
root cause analysis on your observation.
The cause for the batch failure was due to the campaign
manufacturing.
Corrective action:
We are implemented the duration time for manufacturing
and proper cleaning procedures.
And proper training program for the personnel in
manufacturing and cleaning personnel.
