Drug delivery device development
Design and engineering experts in advanced drug delivery systems
TTP is trusted by nine of the top ten global pharmaceutical leaders to solve complex drug delivery challenges. As a design and engineering consultancy specialising in advanced drug delivery devices and combination products, we help teams take devices from blank sheet to clinical reality, addressing challenges such as high-viscosity biologics and advanced formulations. With deep engineering, scientific and human factors expertise, our team guides you from early feasibility and concept creation through to design, verification, transfer to manufacture and launch. We focus on developing robust, efficient and scalable devices that support therapeutic effectiveness and perform reliably in real-world use.


Expertise in complex drug delivery systems and combination products
Bringing life-changing drug delivery systems and combination products to market is inherently complex. Device teams face challenges around viscosity, manufacturability, usability and regulatory requirements - any of which can delay launch.
TTP’s drug delivery specialists help pharmaceutical and biotech organisations accelerate development, retire risks early and balance the trade-offs required to create robust, commercially successful devices. We have contributed to more than 70 innovative systems, including autoinjectors, inhalation devices, microneedles, infusion pumps and advanced local-delivery systems.
Our core drug delivery expertise includes:
- Parenteral device development for biologics, complex formulations and high-viscosity drugs, including autoinjectors, pens and wearable injectors
- Respiratory drug delivery, including pMDIs, DPIs and nebulisers
- Local and targeted delivery systems, implantables and sustained-release technologies
- Advanced device engineering, human factors insight, modelling, verification, and design for manufacturability
We work in agile, multidisciplinary teams that can adapt rapidly to project needs, resolve technical challenges early and prevent costly downstream issues. Using first-principles engineering, scientific rigour and probabilistic methods, we identify variability in materials, processes and user interaction to set specifications that ensure consistent device performance throughout the lifecycle.
This approach is why global pharma and biotech companies bring us their most critical, high-impact programmes, and why our work has enabled launches such as AstraZeneca’s Symbicort® dose counter.

Parenteral device innovation: autoinjectors, pens and wearables
TTP' has a proven track record in the drug delivery product development process, particularly parenteral device innovation, playing a key role in more than eight mechanical injection devices now on the market, with many more in the pipeline.
Our consultants have supported clients on a range of drug delivery technologies - from variable dose pens and autoinjectors to ophthalmic injectors and wearable devices.
Our current work is helping address many of the challenges that the industry is currently facing, such as:
- Developing devices for complex and challenging formulations
We engineer injection devices that reliably handle high-viscosity biologics, particulate suspensions and primary-pack interactions to prevent issues like clogging and delivery failures.
- Engineering reliable, scalable autoinjectors and pens
We resolve performance and reliability issues in autoinjectors, pens and wearables during scale-up by optimising device mechanics, tolerances and assembly processes. Read more.
- Designing sustainable next-generation injection devices
We create ISO 11608–aligned parenteral systems that integrate reusable elements, recyclable materials and separability to meet sustainability goals without compromising performance or usability.
Explore how TTP is advancing next-generation drug delivery solutions for advanced therapies, addressing challenges in high-viscosity mAbs and particulate suspensions through expertise in fluid dynamics, material science, and patient-focused design.


Accelerating respiratory drug delivery device development - pMDIs, DPIs, and nebulisers
Respiratory drug delivery requires alignment of formulation, aerosol science, device design and manufacturability to ensure consistent and effective dosing, patient ease-of-use, and scalable production. Each component influences the other - formulation impacts aerosol performance, which shapes device design, and manufacturability determines production feasibility. TTP’s expertise minimises risks, mitigates delays, and accelerates time to market by enabling optimisation across all areas.
We’ve developed more than 35 respiratory devices ranging from simple to advanced systems - including pMDIs, DPIs, soft mist inhalers, mesh nebulisers and other delivery devices - many of which are now market-leading products.
With deep scientific understanding and cross-industry insight, we drive innovation in both next-generation devices and generics - even in crowded IP landscapes.
As respiratory drug delivery advances, we lead the way in developing technologies essential for future therapies like biologics, mRNA and other future therapies.
Discover how TTP’s TouchSpray™ atomiser technology revolutionised respiratory drug delivery, powering the PARI eFlow® nebuliser to cut treatment time by 50% while delivering 90% drug efficacy and unmatched portability for patients worldwide.


Local and targeted drug delivery systems and implantable devices
Targeted drug delivery promises to revolutionise treatment efficacy by concentrating therapeutics at the site of action while minimising systemic exposure. From oncology to neurology, ophthalmology to pulmonary delivery, these therapies demand delivery systems that are not only scientifically robust but finely tuned to the anatomical, physiological and pathological nuances of the target site.
At TTP, we’re helping our partners navigate the complexity of local and targeted delivery. Our multidisciplinary teams combine deep understanding of tissue biology, pharmacokinetics and advanced materials with engineering excellence to design devices and procedures that deliver with pinpoint accuracy and inspire clinician confidence in a surgical environment.
We have expertise in a wide range of delivery modalities, including:
- Intraocular and intravitreal injectors designed for sustained or repeated dosing
- Intratumoural delivery systems optimised for localised chemotherapy or immunotherapy
- Implantable and biodegradable devices enabling sustained release at the target site
Our solutions are underpinned by first-principles thinking and modelling of tissue interactions, device mechanics, and human factors - ensuring performance from bench to bedside. With patient comfort, clinical usability, and manufacturing feasibility built in from the start, we help you unlock the potential of localised drug delivery to achieve better therapeutic outcomes, faster.
