Chapter 139: Clinical Trial Planning
Zhang Chen returned to Mona's hospital room again.
"Mona, let's go back to the company first, don't worry, there must be no problem."
"Okay, Mr. Zhang, you can go back first, don't worry about me." Mona replied.
"Zhang Chen, I'll stay here with Lao Jiang."
Tian Wenbin decided to stay in the hospital because he wanted to know the results of the examination as soon as possible.
These two people can be said to care more about the data of this clinical trial than Zhang Chen, and would rather stay in the hospital all the time, just to see the latest results.
Zhang Chen nodded and returned to the company with Zhang Yue.
For him, there is no sense of expectation for the clinical trial of this drug.
It's like watching a TV series that has been spoiled, and the process seems to have no sense of expectation, because all the plots are known in advance.
And the final result of the clinical trial of this drug, Zhang Chen could have predicted it a long time ago, and it will definitely pass in the shortest possible time.
Just like last time, Zhang Guoyuan had a heart attack, and it only took a little more than half an hour to completely cure.
If you change to a disease such as high blood pressure, which has milder symptoms, it can be completely cured in less than half an hour.
Of course, the entire clinical trial still needs to follow the previously designed trial formula.
The important thing is to monitor the patient's status after cure, which is the most time-consuming.
The number of patients required for the first phase of clinical trial is 20-100 people, and the safety of the drug is mainly investigated.
The second phase of clinical trial requires hundreds of patients, and the main investigation is the effectiveness of the drug, and the dose-response relationship between the drug dose and the efficacy, while continuing to observe the safety of the drug.
Phase III clinical trials require hundreds to thousands of patients, and the safety of the drug remains the focus, while the efficacy is observed.
Phase IV clinical trials are clinical studies conducted after the launch of new drugs, but this is based on the specific situation, and not all drugs are in phase IV clinical trials.
When designing the clinical trial formula, in order to dispel doubts, Zhang Chen deliberately extended the testing time to one day.
For the number of subjects, Zhang Chen directly selected 100, so that he could get the most powerful data proof.
Wait until tomorrow, and multiple subjects will try the drug together.
However, the testing time remains the same for one day.
Safety is of paramount importance, and there is no room for sloppiness, although Zhang Chen knows that there is nothing wrong with this medicine, others don't know.
Tian Wenbin and Jiang Lu, who have been following up the project, are willing to stay in the hospital in order to see the data as soon as possible.
Obviously, they don't have absolute confidence in this drug either.
Although the data on animals is perfect, it is now a human trial, and the nature is completely different.
No matter how thoroughly humanized experimental animals are, animals are always animals, and there are still essential differences between them and humans.
Moreover, the technical level of humanized experimental animals on the market is not enough at all.
If they had used their own company's experimental animals at that time, it is estimated that Tian Wenbin and Jiang Lu would have been more confident.
Zhang Chen plans to set off for the Nanfan base after the phase I clinical trial is completely on track.
For this reason, he specially called Li Lao to explain the situation.
After returning to the company, Zhang Chen went to pay attention to the breeding of experimental animals.
After seeing that there are no problems, go back to the office and start the study plan for today.
Now the sales of Hefeng soybeans have not gone up, relying on the previous products, the minimum is almost 600 points per day.

Sometimes there are more points, and it can reach more than 800 points.
It depends on the sales volume of the sequencer.
Tens of millions of devices are really not something that ordinary companies can afford.
Recently, the sales of reagents supporting the sequencer have begun to gain momentum, and the reagents that came with the previous ones have almost run out.
Many companies and institutions that have purchased sequencers have tasted the sweetness and have begun to purchase a large number of supporting reagents.
This made the original daily income of 500 points rise to 600 points.
Zhang Chen is very satisfied with the current situation, in less than two months, several products have been launched, and the point income can be stabilized.
As long as it can continue to develop, biovehicles, panaceas, and life extensions can all be done.
Shaocheng University.
At this time, Song Bowen was happily sharing his magical experience with his little junior sister.
"Senior Sister Xiaoya, don't believe it, Mr. Zhang directly transferred an article in a natural journal to me, and I am the first author."
"You just blow it, articles that can be published in nature journals are all experimental results that can only be done by big bulls, how can they be given to you?"
Tang Xiaoya said with a wrinkled nose.
She clearly didn't believe anyone would give such a big gift.
It's not that it's not okay to transfer papers, it's an article that hasn't been published yet, as long as the author agrees, let whoever you want to be in a work.
And even if it is a paper that has already been published, intellectual property rights can be transferred, which is something that many people know.
Of course, in reality, no one would be stupid enough to do such a thing.
The results of scientific research that have been worked hard for several years, or even more than ten years, are transferred to others?
How is that possible, and there is no pay, just to let that George lose that bet?
"Harm, I'll tell you......"
Song Bowen was about to continue to explain, when his mobile phone rang.
When I looked at the phone, the caller ID turned out to be from Yingguo.
Song Bowen was a little excited, it must be that the paper has a result.
After receiving the article forwarded to him by Zhang Chen, he immediately sent it to Hansen's private mailbox.
It's only been two hours, and that's the result?
Song Bowen took the mobile phone and glanced at Tang Xiaoya, and said: "This may be the phone number of the editor of the natural journal, Xiaoya, you speak well, please help me translate it later, my English has been very lame." ”
"Oh, good...... Ok no problem. ”
Tang Xiaoya was a little surprised, could it be that Mr. Zhang really transferred an article to Senior Brother Song?
"Hello, is this Mr. Song?"
The phone was connected, and Hansen asked.
The first thing he did after arriving at the company was to send Song Bowen to him the article and submit it for review in a timely manner.
Now that it has arrived at the review department, according to the progress, it is estimated that it can be published together with Zhang Chen's five articles.
"It's me, who are you?"
Song Bowen can still understand this simple sentence in English, and he immediately replied.
Hansen said politely: "Hello Mr. Song, I am Hansen, the editor of the Nature journal, and I am calling, mainly to tell you that the article you submitted is already going through the publication process, and it is estimated that it will be published in a few days."
In addition, I have to trouble you to fill in the open source license as soon as possible, you don't have to worry about the layout fee, the quality of your article is very good, and it is completely worthy of us to publish it for you for free. ”
Hansen thought that this article was Song Bowen's own work.
In his opinion, the people the elder knows are really different, Zhang Chen can publish high-quality articles, and his colleagues can also publish them, but the number is slightly lacking.
With such a large paragraph, Song Bowen was a little confused.
However, I am also a Ph.D. who is about to graduate, and the editor of a natural journal, I still understand these English words.
But the rest is not very understood.
He was excited in his heart, and turned his head to look at his little junior sister Tang Xiaoya in confusion.
But Tang Xiaoya looked at her senior brother with a shocked face, and forgot to translate him in real time for a while.
