Simulations Plus, Inc., incorporated in 1996, develops and produces software for use in pharmaceutical research and for education, as well as provides contract research services to the pharmaceutical industry.

We currently offer five software products for pharmaceutical research: ADMET Predictor™, MedChem Designer™, MedChem Studio™, DDDPlus™, and GastroPlus™. We call the combination of ADMET Predictor, MedChem Studio, and MedChem Designer our ADMET Design Suite™.

ADMET Predictor™

ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) Predictor is a computer program that takes molecular structures as inputs and predicts over 140 different properties for them at the rate of about 200,000 compounds per hour on a fast laptop computer. This capability allows chemists to get estimates for a large number of important properties without the need to synthesize and test the molecules. ADMET Predictor has been consistently top-ranked for predictive accuracy in peer-reviewed, independent comparison studies, while generating its results at a very high throughput rate. The current state-of-the-art of this type of software does not enable finding the best molecule in a series, but it does allow identifying molecules that are highly likely to fail as potential drug candidates (the worst molecules, which is usually the majority of a chemical library) before synthesizing and testing them. Thus, millions of "virtual" compounds can be created and screened in a day, compared to potentially months of work to actually synthesize and test a much smaller number of actual compounds.

The ADMET Modeler™ subprogram that is integrated into ADMET Predictor enables scientists to use their own experimental data to quickly create high-quality, proprietary predictive models using the same powerful modeling methods we use to build our top-ranked class property predictions. Pharmaceutical companies expend substantial time and money conducting a wide variety of experiments on new molecules each year, resulting in large databases of experimental data. Using this proprietary data to build predictive models can provide a second return on their investment; however, model building has traditionally been a difficult and tedious activity performed by specialists. The automation in ADMET Modeler makes it easy for a scientist to create very powerful models with a minimum of training.

We are now examining a very different application of this modeling engine - building predictive models for missile aerodynamic force coefficients as a function of missile geometry, Mach number, and angle of attack. This problem was identified by the Aerospace Engineering department at Auburn University, and working with them, we have done some preliminary testing of the modeling engine in ADMET Modeler for this type of problem. Results have been very encouraging, and we believe there are government agencies and industrial aerospace companies that will find such a capability to be highly useful.

We released Version 6.5 of ADMET Predictor during last fiscal year. This version extended our metabolism predictions by training on a much larger experimental data set, and for the first time, provided specific metabolism rates for individual atoms within a molecule, rather than only for the molecule as a whole. These improvements are also available via MedChem Designer and MedChem Studio for customers who license ADMET Predictor. Version 6.5 also adds confidence levels to most of our toxicity models so that users have an idea of the reliability of each individual prediction.

We are now finalizing version 7.0, which we expect to release early in calendar 2014. This new version will incorporate a new model for predicting ionization constants (pKa's) developed in a collaboration with Bayer AG that enabled us to more than double the size of our data set from about 16,000 pKa values to more than 35,000, and to expand the chemical space it covers to include a larger number of molecules more like those of interest to the pharmaceutical industry today. We believe the resulting improvement in pKa prediction puts our already best-in-class model well in front of any competitor. Predicting ionization is critical to predicting most other properties, so all of our models (approximately 144) are being retrained based on this new capability for version 7.0.

MedChem Designer™

MedChem Designer was launched in 2011. It was initially a molecule drawing program, or "sketcher", but now has capabilities exceeding those of other molecule drawing programs because of its integration with both MedChem Studio and ADMET Predictor. We provide MedChem Designer for free because we believe that in the long run it will help to increase demand for ADMET Predictor and MedChem Studio, and because most other existing molecule drawing programs are also free. Our free version includes a small set of ADMET Predictor property predictions, allowing the chemist to modify molecular structures and then see a few key properties very quickly. The chemist also sees that with a paid ADMET Predictor license, the entire 144 predictions would be available.

We released MedChem Designer 2.5 during FY2013. This new version provides the chemist the specific predicted atom locations for metabolism by each of the enzymes predicted to act upon a molecule.

When coupled with a license for ADMET Predictor, MedChem Designer becomes a de novo design tool for medicinal chemists. With it, they can draw one or more molecular structures, then click on the ADMET Predictor icon and have over 140 properties for each structure calculated in seconds, including our proprietary ADMET Risk™ index. Scientists can also click on an icon to generate the likely metabolites of a molecule and then predict all of their properties from ADMET Predictor, including their ADMET Risk scores. This is important because a metabolite of a molecule can be harmful even though the parent molecule is not.

ADMET Risk provides a single number that tells the chemist how many default threshold values for 24 predicted properties were crossed (or violated) by each structure. The rules can be modified and new rules added by the user to include any desired rule set based on any combination of calculated descriptors, predicted properties, and user inputs. Thus, in a single number, the chemist can instantly compare the effects of different structural changes in many dimensions. As chemists attempt to modify structures to improve one property, they often cause others to become unacceptable. Without ADMET Risk, the chemist would have to separately examine many key properties for each new molecule (and its metabolites) to check whether any became unacceptable as a result of changing the structure.

We are now finalizing the next release of MedChem Designer, which will add the ability to capture the image of a molecular structure with a new snapshot tool, and the program will automatically convert the graphic image into any of several computer-based chemical structure files. Converting from lines and letters on the screen to an exact chemical representation of the molecule (Optical Structure Recognition, or OSR) is a complex task. Although a few OSR programs are in existence, we are not aware of any that can accurately convert as many varieties of images to chemical representation as the OSR tool within the development version of MedChem Designer. Such a capability allows chemists to quickly capture molecular structures from the scientific literature to use in our simulation and modeling software.

MedChem Studio™

Over the past several years, MedChem Studio updates have resulted in a very powerful tool for medicinal and computational chemists for both data mining and for designing new drug-like molecules. We released version 3.5 of MedChem Designer during FY2013. The new features are too numerous to list, but include such important items as:

A new licensing module from Flexera called FlexNet™

Improvements to graphics in structure depictions and the Miner 3D module

Faster performance on large data sets

A 64-bit version to deal with much larger data sets

While MedChem Designer can be used to refine a small number of molecules, MedChem Studio can be used to create and screen (with ADMET Predictor) a very large number of molecules down to a few promising lead candidates. MedChem Studio has features that enable it to generate very large numbers of new molecular structures using a variety of de novo design methods. Coupled with ADMET Predictor and MedChem Designer, we believe the programs provide an unmatched capability for chemists to search through large libraries of compounds that have undergone high-throughput screening experiments to find the most promising classes (groups of molecules with a large part of their structures the same) and molecules that are active against a particular target. In addition, MedChem Studio can take an interesting (but not acceptable) molecule and, using a variety of design algorithms, very quickly generate many thousands of high quality analogs (similar new molecules) that are predicted (via ADMET Predictor) to be both active against the target as well as acceptable in a variety of ADMET properties.

MedChem Studio version 3.5 was released during FY2013, adding a number of new features, including:

New algorithms for drawing crisper molecular structures

New licensing module from Flexera called FlexNet™

Faster execution speed

64-bit version to allow access to much more memory for very large data sets

User-defined equations to calculate new attributes by combining others

Enhanced Miner3D graphics with expanded assortment of chart types

Current development has focused on the OSR tool mentioned above under the MedChem Designer discussion.

NCE Project

During late 2012, based on our strong belief in the exceptional capabilities of our ADMET Design Suite (MedChem Studio/MedChem Designer/ADMET Predictor), we initiated a new molecule (NCE, or New Chemical Entity) design project. After considering various targets, we selected the malaria parasite Plasmodium falciparum, both because of the unmet need for a very low-cost cure, and because we believed that external funding opportunities might exist if we were successful in generating high-quality lead compounds using our software. Our goal was to demonstrate how well the ADMET Design Suite worked to generate new lead molecules in a fraction of the time and cost normally required in the pharmaceutical industry. We completed the design process in September 2012 and we announced that we had requested quotations from chemical synthesis companies for the cost and time to make a small set of molecules. Five molecules of our own design and two precursors (almost the final designed structures, but a step away in synthesis) were synthesized and tested for inhibition of the parasite at the University of California at Riverside. We were hoping that at least one would show inhibition of the growth cycle of the parasite.

We were excited to learn that every molecule showed activity against the parasite at less than micromolar concentrations, with two showing activity at less than 100 nanomolar concentration (high potency) against the drug-sensitive strain of the parasite. They were then tested against the newer drug-resistant strain of the parasite, and again potency was observed, with two molecules showing nanomolar activity. We believe this exercise - a software company using its own products to design novel molecules and have them synthesized and tested
- is unprecedented. New software license sales resulting from presenting our results have already more than recovered our investment.

During the previous reporting period, we announced that we had completed the design of a number of new molecules for a different target - the cyclo-oxygenase-2 (COX-2) enzyme that is the target for Celebrex®. Celebrex is the only COX-2 inhibitor remaining on the market, after the withdrawal of other approved drugs (such as Vioxx®) due to cardiac toxicity. Our chemical synthesis contractor has been working on developing the synthetic methods to make these new molecules and has now completed synthesizing sufficient material for four of the molecules to allow for testing them for activity. Samples of these new molecules are being sent out to a laboratory to measure activity against both COX-2 and COX-1 enzymes (COX-1 is inhibited by aspirin and other drugs). The reason for also testing against the COX-1 enzyme is that it appears from the scientific research that was conducted after the withdrawal of other COX-2 inhibitors from the market that it is important to inhibit both COX-2 and COX-1 at a certain ratio in order to provide the benefits of COX-2 inhibition without the cardiotoxicity risk that has been associated with inhibiting COX-2 alone. We designed our new molecules based on activity models we built for both COX-2 and COX-1 built from public data, with the goal of providing an acceptable ratio of COX-2 to COX-1 inhibition. This is much more challenging than designing for a single target, as we did for the earlier malaria NCE project.


DDDPlus simulates in vitro laboratory experiments used to measure the rate of dissolution of the drug and, if desired, the additives (excipients) contained in tablets and capsules under a variety of experimental conditions. This software program is used by formulation scientists in industry and the U.S. Food and Drug Administration (FDA) to (1) understand the physical mechanisms affecting the dissolution rate for various formulations, (2) reduce the number of cut-and-try attempts to design new drug formulations, and (3) to design in vitro dissolution experiments to better mimic in vivo conditions.


Our flagship product and largest source of revenues is GastroPlus. GastroPlus simulates the absorption, pharmacokinetics, and pharmacodynamics of drugs administered to humans and animals, and is currently in widespread use at pharmaceutical companies, the FDA, the U.S. National Institutes of Health (NIH), and other government agencies in the U.S. and other countries. Because of the widespread use of GastroPlus, we were the only non-European company invited to join the European Innovative Medicines Initiative (IMI) program for Oral Bioavailability Tools ("OrBiTo"). OrBiTo is a collaboration among 27 industry, academic, and government organizations working in the area of oral absorption of pharmaceutical products. Because we are outside of Europe, our participation in this project is at our own expense, while other members are compensated for their work; however, we are a full member with access to all of the data and discussions of all other members. We believe participation in this initiative enables us to benefit from and to contribute to advancing the prediction of human oral absorption from preclinical data, and ensures that we are in front of the audience of member pharmaceutical companies and regulatory agencies.

Version 8.5 of GastroPlus was released during the current reporting period, adding a number of important new capabilities requested by customers as well as improvements we have identified in-house, including:

A new model for precipitation based on classical nucleation theory

Infant physiologies, including for babies born as much as 16 weeks premature

A unique method for using transporter data from preclinical experiments to predict transporter effects in human and other animals

A number of additional expression levels of enzymes and transporters in human and animal physiologies

GastroPlus version 9.0 is now in development. This version will add the ability to simulate dermal (through the skin) drug absorption from patches, creams, and ointments. This capability has been in development since May of 2012 through a funded collaboration with a top-5 pharmaceutical company, and is in final testing at this time. A number of other improvements will be included in version 9.0 that will be announced with the release of the product. An interim release
(8.6) is planned for the very near future to enable certain customers to take advantage of a new physiological model for minipig, which has become a more frequently used animal species in preclinical development, and to add the ability to simulate more than two drugs for drug-drug interactions.


MembranePlus is a new product that has been under development for a number of years, but was put on hold for several years due to other priorities. It was revived in the past year and is now nearing commercial release. Like DDDPlus, MembranePlus simulates laboratory experiments, but in this case, the experiments are for measuring permeability of drug-like molecules through various membranes, including several different cell cultures (Caco-2, MDCK) as well as artificially formulated membranes (PAMPA). The value of such a simulation results from the fact that when the permeabilities of the same molecules are measured in different laboratories, results are often strikingly different. These differences are caused by a complex interplay of factors in how the experiment was set up and run. MembranePlus simulates these experiments with their specific experimental details, and this enables the scientist to better interpret how results from specific experimental protocols can be used to predict permeability in human and animals, which is the ultimate goal. MembranePlus is unique and our customers have expressed significant interest in the new capability.

We plan to release version 1.0 of MembranePlus by March 2014.

Contract Research and Consulting Services

Our expertise in oral absorption and pharmacokinetics is evidenced by the fact that our staff members have been speakers or presenters at over 80 scientific meetings worldwide in the past four years. We frequently conduct contracted studies for large customers (including the largest five pharmaceutical companies) who have particularly difficult problems and who recognize our expertise in solving them, as well as for smaller customers who prefer to have studies run by our scientists rather than to license our software and train someone to use it. The demand for our consulting services has been steadily increasing, and we have expanded our studies to meet the increased workload. Long-term collaborations and shorter-term consulting contracts serve both to expand and showcase our technologies, and to build and strengthen customer relationships.

During the first quarter of fiscal year 2014 we continued to work on our 5-year collaboration agreement with the Center for Food Safety and Applied Nutrition (CFSAN) of the FDA. FDA scientists and our scientists are using ADMET Predictor/Modeler to build predictive models for likely toxicities of food additives and contaminants. During the first part of this collaboration, we analyzed FDA databases and worked with FDA scientists to ensure that the FDA data to be used for building new predictive models is as accurate as we can reasonably make it. Both FDA scientists and our scientists are building a series of models to classify new compounds as toxic or nontoxic from FDA datasets. Included early on in this effort was a special modification to ADMET Predictor to allow the user to set a minimum value for specificity or sensitivity when building a model, and this is now a standard part of the program available to all users. Sensitivity refers to how well a model identifies toxic (or any other property) compounds. A model that determined all compounds are toxic would have 100% sensitivity, because all toxic compounds would be labeled as such; however, all nontoxic compounds would also be labeled toxic. Specificity refers to how well a model distinguishes between toxic and nontoxic compounds. Increasing one usually results in decreasing the other. Depending on the purpose of the model, some scientists will prefer to train models that emphasize one statistic over the other.


Our business strategy is to do the things we need to do to promote growth both organically (by expanding our current products and services through in-house efforts) and by acquisition. We believe in the "Built to Last" approach - that the fundamental science and technologies that underlie our business units are the keys both to improving our existing products and to expanding the product line with new products that meet our various customers' needs. The search for suitable acquisitions continues to be a high priority.

With our significant cash reserves, we continue to seek suitable acquisitions. Because we have been unable to identify suitable acquisitions and our cash continues to accumulate, the board of directors declared a $0.05 per share per quarter cash dividend that began in February 2012 and was paid in May, August, and November 2012. The board declared an accelerated cash dividend consisting of the February, 2013 dividend of $0.05 per share per quarter plus $0.03 per share from each of the expected May, August, and November 2013 dividends of $0.05 per share per quarter for a total of $0.14 per share, which was distributed on December 28, 2012, in order to provide our shareholders with the income tax benefits from lower capital gains rates in 2012 over 2013. We declared and paid a $.04 per share dividend in November 2013. A dividend of $0.05 per share per quarter is anticipated going forward; however, there can be no assurances that such dividends will be distributed, or if so , whether the amounts will be more, less, or the same as expected. The Board of Directors must approve each dividend distribution and may decide to increase, decrease, or eliminate dividend distributions at any time.

Net Sales

Net sales increased $351,000 or 15.3%, to $2,641,000 in the first fiscal quarter of Fiscal Year 2014 ("1QFY14") from $2,290,000 in the first fiscal quarter of Fiscal Year 2013 ("1QFY13)". We attribute the increase in revenues due to an approximately $435,000 increase software license revenues. Analytical study revenues were up $53,000. However, we were not involved in any collaboration studies in 1QFY14; therefore, net revenues for studies and collaborations decreased $58,000. In addition, training revenues declined by $26,000 as fewer training session were performed in FQ14.1.

Cost of Sales

Cost of sales increased by $61,000, or 15.9%, to $448,000 in 1QFY14 from $387,000 in 1QFY13. As a percentage of revenue, it also increased from 16.9% in 1QFY13 to 17.0%. A significant portion of cost of sales for pharmaceutical software products is the systematic amortization of capitalized software development costs, which is an independent fixed cost rather than a variable cost related to sales. This amortization cost increased approximately $10,000, or 5.4%, in 1QFY14 compared with 1QFY13. Royalty expense, another significant portion of cost of sales, increased approximately $34,000, or 25.5%, in 1QFY14 compared with 1QFY13. We pay a royalty on the core GastroPlus software licenses but not on its optional modules. The majority of the royalty costs increase was related to an increase in Gastro Plus license revenues. We also pay royalties to Accelrys on a portion of the ADMET Predictor Metabolism Module. Salaries related to analytical studies increase 33,000 in 1QFY14 compared with 1QFY13.

Gross Profit

Gross profit increased $290,000, or 15.2%, to $2,193,000 in 1QFY14 from $1,903,000 in 1QFY13. We attribute this increase to increased revenue outweighing increased cost of sales.

Selling, General and Administrative Expenses

Selling, general, and administrative (SG&A) expenses increased $140,000, or 15.0%, to $1,071,000 in 1QFY14 from $931,000 in 1QFY13.

The major increases in SG&A expense were:

· Commission expense - we incurred commissions to our Japanese and Chinese dealers as they increased their sales. Commissions were up by $29,000.

· Salaries and wages increased by $55,000. In the 1QFY14 greater portion of time was spent on R&D and projects that were capitalized than in 1QFY14.

· Trade shows, marketing labor, and travel costs - We continued to increase our visibility at tradeshows and conferences, increasing spending in these areas by approximately $38,000.

The major decreases in SG&A expense were:

· We incurred $36,000 less in M&A consultant fees in 1QFY14 vs 1QFY13.

· We reduced advertising by $10,000 in 1QFY14 vs 1QFY13.

Increases in SG&A expenses outweighed decreases.
