Imaging
Altasciences has performed well over 20 studies requiring different imaging modalities. Our sites have access to X-ray, CT, MRI, ultrasound and DEXA scanners at radiology clinics, and endoscopy and colonoscopy through gastroenterology clinics. Our partners’ facilities are in the same building as our clinics, or within a few minutes’ drive.
The imaging is conducted to validate inclusion/exclusion criteria as pharmacodynamic measures, or to guide injections by ultrasound. Regardless of the objective, we ensure that the imaging process is designed to meet your study requirements, including working with radiology clinics approved by central imaging providers to review the procedures and validate test images as required.
RENAL AND HEPATIC IMPAIRED
We have designed, conducted, analyzed, and reported on a large number of renal and hepatic impaired studies in recent years, across the spectrum of therapeutic areas. We partner with leading external sites to ensure that our renal and hepatic impaired patients have the specialized clinical oversight they need, and we leverage their databases to ensure we access the patient populations you need.
For renal impaired studies, we partner with Hôpital Maisonneuve-Rosemont (HMR), located near our Montreal clinic. HMR recruits and treats the severely and moderately impaired groups, and the Altasciences clinic completes with the mildly impaired and healthy matches. We have used this approach for more than 10 studies and usually conduct the clinical trial in less than three months.
For hepatic impaired studies, we work with leading sites in the U.S. and Canada. Depending on the need to include severely impaired patients, and the full inclusion/exclusion criteria, we conduct the studies with two to five sites. Our Project Managers simplify the multi-site process by providing one point of contact, and ensuring recruitment proceeds according to plan.

QT ASSESSMENT
We work with you to determine the ideal approach for measuring the QT prolongation effect of your new compound or formulation by partnering with core ECG labs for the data collection and analysis.
Some sponsors choose to add early cardiac safety assessment to their first-in-human studies, while others wait for later development and perform a Thorough QT prolongation study. Regardless of your approach, Altasciences can help you with the design. We have conducted 11 studies involving cardiac Intense/concentration QT/TQT (IQT/TQT) since 2016.
The design and conduct of studies focused on ECG measurement revolve around reducing variability in the measures, as this allows the studies to be conducted with smaller sample sizes. We consider the impact of clinical events like blood draws, and also limit other stimuli. We ensure that when the ECGs are taken, there are no events that affect heart rate.

DRUG-DRUG INTERACTION
Drug-drug and drug-alcohol interaction studies range from simple two-way crossover studies to complex, multi-cohort, adaptive designs. Altasciences has designed, conducted, analyzed, and reported on hundreds of these studies — from the simplest to the most complex.
Our pharmacokineticists review the investigator brochure to determine the studies required, and the ideal inhibitor, inducer, or substrate to use. Our bioanalytical department has validated methods, and we have clinical experience, with almost all common substrates. Our designs are based on literature and in-house experience.
We have conducted single interaction, multiple interactions across cohorts, or multiple interactions within a cohort (cocktail) studies. We routinely perform CYP genotypic to exclude subjects or stratify the groupings.

First-In-Human Trials (FIH)
We have decades of first in human trial experience, designing, conducting, analyzing, and reporting on FIH studies for small molecules and biologics, and we offer the opportunity to begin the regulatory process in either the U.S. or Canada. Our clinical pharmacologists are proficient at designing NDA-enabling studies, including single and multiple ascending dose studies, as well as testing for various effects, such as age, gender, and food. Our first in human trials routinely include assessments of biomarkers or symptom assessments to establish proof of concept. Our toxicologists provide support in calculating starting doses, and work with our clinicians in determining the best Phase I clinical trial monitoring practices for effects observed during preclinical trials.
Our clinics have purpose-built units that offer the stringent patient oversight required to safely perform ascending dose studies required. Before starting each FIH study, our clinical teams perform a risk assessment to ensure we are appropriately staffed and resourced to ensure participant safety for your critical FIH trials.
We have the recruiting experience and capacity to quickly fill FIH study cohorts that are dosed weekly, and can add patient cohorts or conduct entire studies in patients, as needed.
Consult our FIH Fact Sheet.
Human Abuse Potential
Altasciences has conducted over 50 human abuse potential (HAP), abuse deterrent formulation (ADF), or substance abuse studies since 2008, including through repeated multi-year contracts with the NIH and the FDA. HAP studies may be required by the FDA as part of the safety evaluation for New Chemical Entities (NCEs) that are CNS-active, chemically or pharmacologically similar to other drugs with known abuse potential, or produce psychoactive effects such as sedation or euphoria. ADF trials are often pursuant to a 505(b)(2) or Hybrid strategy. The complicated regulatory pathway for HAP and ADF protocol designs (selection of comparator, recruiting, etc.) requires individualized consulting for each type of study.
Our physicians work with both recreational drug users and substance-dependent participants, and have significant expertise in the identification of appropriate subjects for substance abuse studies. We have the specialized pharmacy facilities and locations to ensure appropriate manipulation of many abuse-deterrent formulations.
Our clinical sites have robust databases of recreational abusers of opioids, stimulants, sedative hypnotics and cannabinoids, including abuse by oral, parenteral or nasal routes. Our upscale facilities contribute to industry-leading retention rates for up to 60 days of consecutive confinement.
Altasciences’ adaptive clinical pharmacology unit in Kansas City provides a highly reconfigurable and adaptable space for conducting complex clinical trials with challenging subject populations. The 30-bed locked, limited-access, self-contained unit allows sponsors to control every aspect of the study environment as it relates to the special needs of the unique study population or the specific requirements of the protocol, and makes it possible for them to obtain key efficacy data earlier in their development process.
We partner with Cambridge Cognition for VAS scale collection for pharmacodynamic measures, such as drug liking. Our experienced clinical staff is retrained on use of the tablet-based software before each study. We also educate participants on system use and relevant details, such as the difference between unipolar and bipolar scales. We ensure there is a 1:1 staff to participant ratio during the collection of this vital data.

Driving Simulation
With the finalization of the FDA guidance in 2017, driving simulation studies are now required for any drug that may affect cognition. Driving simulation studies are the ideal way to collect data required for the drug label when pre- and early clinical studies show that a drug may cause somnolence or impair cognition. Our experts can design and conduct driving simulation studies to efficiently determine the extent and duration of driving ability impairment.
At Altasciences, we design driving studies to achieve your objectives, leveraging extensive experience across clinical testing of cognitive effects. We partner with Cognitive Research Corporation to use their proprietary driving simulators, nine of which are permanently installed in our clinic. We have performed well over 10,000 simulated drives to date, analyzing the impairment seen at peak exposure and/or the effect seen the morning after evening dosing.
We have a suite of ten simulators on site at our clinical facilities, with space for more than 20 additional, as needed. Professional oversight is provided by fully-certified, in-house driving simulation study specialists.

Proof of Concept (POC) Study Conduct Expertise
Our clinical pharmacologists perform background research, and consult with research specialists, to ensure we craft the ideal design to meet your objectives, including collaborating with our preclinical colleagues to select the models or biomarkers that translate from preclinical to clinical. Our clinical trial teams capture the endpoints in a consistent manner, training our staff to administer both objective and subjective proof of concept study tests in the exact same way. We also carefully educate participants in what is expected of them during a Phase I clinical trial.
We routinely perform POC clinical research in healthy participants, and leverage our access to a wide range of patient populations for indications that do not have models appropriate in healthy participants. Prior to starting a proof of concept study, our recruiting department produces an accurate estimate of recruitment numbers and timelines. For some indications, we can recruit a large number of patients (i.e., more than 50 patients in areas like diabetes, obesity, and osteoarthritis), while in others, we conduct POC research with smaller groups.
ISSUE NO. 7 — Understanding the Intrinsic and Extrinsic Factors that Alter Drug Exposure and Toxicity

Intrinsic factors such as age, biological sex, comorbidities, or genetics can potentially alter drug exposure, as can extrinsic factors such as concomitant drugs, supplements, the environment, and food and beverages. One of the most important factors to consider during the course of your early-phase clinical research is drug-drug interactions (DDIs), which occur when one drug alters the effect of another, either by reducing its effectiveness or elevating systemic concentrations to potentially dangerous levels—ultimately causing side effects.
In some cases, these side effects could be life-threatening, such as drops in blood pressure, irregular heartbeats, or organ damage.
In Issue 7 of The Altascientist, we delve into these factors, the importance of drug interaction studies, and how to limit adverse effects and maximize treatment response. Listen to the audiobook or download the PDF below, to learn more about:
- key factors to consider in drug development (age, biological sex, genetics, DDIs);
- examples of common DDI involving the cytochrome P450 enzyme system; and
- drug interactions and guidance for marketed drugs.
The issue also features a drug-drug interaction case study, in which the effects of two doses of a sponsor’s investigational product on the pharmacokinetics of multiple oral doses of clopidogrel, and a single dose of warfarin in healthy adult subjects were evaluated.
Identifying Drug-Drug Interactions (DDIs)
The increasing number of drugs on the market has led to a greater potential for drug-drug interactions, and more complex drug regimens with multiple compounds administered to treat one condition or different compounds given to treat comorbidities, are also contributing factors. These interactions must be identified during the development process as part of the assessment of the drug’s risks and benefits.
According to the FDA’s 2024 guidance titled M12 Drug Interaction Studies, clinically significant DDIs between investigational and other drugs should be addressed at various stages of drug development. They should also be thoroughly understood through nonclinical and clinical studies by the time the drug is approved, monitored after approval, and clearly communicated in the drug's labeling to ensure proper management strategies for clinically significant DDIs and safety. In M12, the FDA states, “The potential for an investigational drug to cause DDIs should be investigated in a stepwise manner during drug development. The potential for an investigational drug to cause pharmacokinetic interactions both as an object (effect of other drugs on the investigational drug) and as a precipitant (effect of the investigational drug on concomitant drugs) should be evaluated.”
