Round 1

Reviewer 1 Report

The author has argued for relaxing GMP production guidelines for phages. While it is true that phages are less understood mode of therapeutics, it is even more important to have good manufacturing practices for phages so they are reliably manufactured and studied in clinical settings. Already, there is a bias of publishing positive results and not the negative ones. On top of that, if we have to relax GMP standards, the clinical studies would produce only worthless data and eventually, this would hurt the field very badly as the prospect of phages becoming therapeutics against resistant bacteria would face a roadblock. This commentary is in that sense going against good science. The author has discussed some historic context of sewage, etc., which is also based on low scientific data and more on hypothesis. Also, the write up has issues with grammar and typos. Although this is a commentary, it does not seem to be based on proper logic and science. It contains too much personal opinion and less of the prospects of the field.

Author Response

I thank the reviewer. I apologize for the many mistakes which are corrected now by a program and the reading of a collague. I was pressed in time for submission. Sorry.

 I added a statement in the Introduction (line 21- 23) perhaps this makes the urgency of this article clearer.

Numerous experiments are summarized and as clear as possible. The reader should unterstand the principles not the details. Therefore I did not change there anything.
I obviously have a different view on  phages  and on GMP than this reviewer. I added a sentence about the future as requested. I see the future in the Belgian approach, new insert line 228-229

The "proper logic" and "science" of this commentary is based on the past and some recent successes. I do not think important studies have been missed. The conclusion is , to use the Belgian approach 

I am aware of the opinion of this reviewer shared by the majority of people and colleagues  - but I would like to point out to a severe problem and point out to an upcoming serious global health crisis. 

 

Reviewer 2 Report

This review manuscript describes history and current status of phage therapy. Considering the importance of phage therapy in the era of antibiotic resistance, it is timely and covers major aspect of phage therapy. Although the manuscript is well written, I would like to point the followings;

1. lines 11-12. I agree phages need to be produced under different regulations than current GMP, but there are GMP produced phages available. For example, Clean Cells in France and Armata in the US.

2. line 112. In PhagoBurn, the phage cocktail contained 12 different phages to treat P. aeruginosa infection, not one kind of phage.

3. There are numerous typos, eg. line 159, Mycobacterium, line 214, phage therapy, line 120, P. (need to be capitalized), line 18, 33,000, and many more.

Author Response

I thank the reviewer for his comments. I want to apologize for the mistakes I was pressed in time for submission. I used a correction program and the help of a colleague.

I corrected the number of phages in PhagoBurn line114 and inserted a sentence on GMP production by Clean Cells Co. line 115-116. . I was surprised that the reviewer wants this to be mentioned.Their GMP prodution consumed most of the gratn.

Reviewer 3 Report

Please provide me back the paper with a deep grammar correction of the English words (example line 29 replace "infectins" with "infections" and "diseses" with "diseases").

Author Response

I am sorry for all the mistakes I was pressed in time when I submitted. They should all be corrected by now. Thank you.
