The development of new drugs requires such a long process from basic research to non-clinical studies, clinical studies, approval process and so forth, and also in general, it is said to take over a period of more than 10 years at a cost of several tens of billions of yen to one hundred billion yen. In addition, as it is necessary to optimize many factors such as drug efficacy, safety, and pharmacokinetics, it is said that the success rate of a lead compound to be launched on the market as a new drug is as low as 1 in a 30,000 possibility, even with the huge cost over a long period of time.

In recent years, methodologies from mathematical simulation and machine learning are attracting attentions from pharmaceutical industry and are expected to achieve development efficiency and cost reduction, for instance, by identifying novel candidate compounds from a large number of compounds rapidly. Also, applying these methodologies to big data analysis in the process of non-clinical studies to select candidate compounds efficiently is also expected to make the drugs reach patients in need of them as early as possible.

In this competition, participants are challenged to create an algorithm to predict pharmacokinetic parameters using multiple descriptors that represent structural chemical, physicochemical and biochemical characteristics of various compounds with the aim of improving the efficiency of new drug discovery process. This is definitely a rare opportunity to deal with the data in the pharmaceutical industry and to contribute to drug discovery.

We are looking forward to your participations.

* This competition is proposed and implemented by SIGNATE as a research project of Takeda Pharmaceutical Company's open innovation program (COCKPI-T® Funding).


Predict pharmacokinetic parameters from compound information and experimental data in the screening test

* Please refer to "Data" page for details such as data format.

Evaluation Function
・Submissions are scored on the coefficient of determination.
・The evaluation value takes a value of 1 or less, and the higher the accuracy, the larger the value.

Determination of winners 
1. Final scorings and rankings will be determined using correct data sets that differ from those used for the contest. The leaderboard display (ranks and scores) will automatically change from running scores to final evaluation scores once the contest has ended.

2. Regarding evaluation-based rankings, the contestant who applied first for participation in the contest will be ranked higher in the case of an identical (tied) score.

3. Subject to the economic burden at the secretariat and guaranteeing that there is no infringement of the right, the following are required to determine winners:
 ・model source code
 ・Trained model
 ・Procedure description document enabling reproduction of the prediction process (must clearly explain preprocessing, learning, and prediction processes. When using pre-trained models, APIs, data other than provided data etc, also specify its source (location of data, link of thesis etc))
・Computer/equipment operating environment information, including OS version, software utilized and analysis methods
・Random number seed (if Random Forest or similar was used to generate random numbers)
・Degree of prediction model contribution for all explanatory variables (when using a method that enables calculation of degree of prediction)
・Insights gained through data interpretation, manipulation and modeling
   (* Please see here for a sample of the winners survey)

4. During the reproducibility evaluation period, the contestant will be disqualified from award eligibility in any of the following cases:
・The contestant does not respond within the specified timeframe to contact from, or a request/demand from, the contest administrative office regarding contest-related procedures
・The contestant fails to adhere to participant requirements, rules, etc.
・The model's prediction results cannot be reproduced
・SMS Verification of account is not completed
When the secretariat judges that it is unfair for other reasons

5. We will select winners from those who can confirm the reproducibility.

Overall ranking
・ This competition is the target of overall ranking (score, medal).

・Please keep in mind to create a practical model as each competition, in principle, has its own goal such as achieving business challenges, solving social problems, and sharing results of studies.
・We expect the implementation in consideration of operability and extensibility. That is, use only the provided data, please make mechanical and automatic processing flows that do not depend on human judgment.

One account per individual
・If you participate as an individual, you can only have one account per person.

Creating a team
・If you want to join a team, you can create a team of up to 5 people, including representative.
・To create a team, please apply for a representative from the "Team Form" button on the upper right of the page.
    * The team can be created by 2019.8.21 (Wed) in this competition.
    * If the team creator (representative) unsubscribes from SIGNATE, the team will be treated as disbanded.
      Please be aware that once a team is disbanded, users who have previously joined as members
      will not be able to contribute to the competition, either as a team or as an individual.
* Please refer to here for details of team functions (

No private sharing
・Sharing code and disclosing information about data (including descriptors) are not permitted.

Data limitations
・It is prohibited to learn the model using external data.
Implementation using a learned model generated from external data or using an external API (such as Google Cloud API) is prohibited.

Other limitations
・You may use any softwares as long as they are open sourced and free (python, R, etc.).
・Please ensure that the proposed method is reproducible and can be used continuously without any additional costs.
・Modeling process should be divided into 3 parts (Preprocessing, Training, and Predicting) and a source code for each part has to be executable independently.

1. Preprocessing
Module that reads supplied data, carries out preprocessing, and outputs each file in a format that can be input into the model. Divide into files for learning and files for evaluation ("get_train_data" and "get_test_data" or similar), and define a function for preprocessing.

2. Training
Module that reads files created in step 1 to enable model learning. Define a function that can output the learning-complete model, amount of characteristic and cross validation assessment results.

3. Predicting
Module that reads the test data created in step 1 and model created in step 2 and outputs prediction results in file format.
