The EMA proposed strategy recognizes the importance of emerging technologies in general and modelling and simulation, also known as in silico methods, in particular. However, the document tends to stress the value of in silico methods almost exclusively in connection with the reduction of animal experimentation. While we agree that this is a relevant application for such methods, it is not the only one and likely not the most impactful one for the patient and for the industry. The term In Silico Trials indicates a number of use cases, not only related to pre-clinical evaluation, but also to the reduction, refinement, and in some cases even replacement of clinical trials.
We wish to collect signatures on the document by as many experts in academia and industry as possible to make sure our voice is heard. We encourage you all to take a minute of your time to fill up this form and help us raising the awareness of your colleagues on this matter.

Electrospun scaffolds for the regeneration of tendons
and ligaments
Summary
Degenerative or traumatic lesions of tendons and ligaments are difficult
to repair. Post-operative failures
affect between 15% and 40% of cases (depending on initial indications). We developed a prototype of an electrospun
scaffold replicating the hierarchical morphology and the mechanical properties
of tendons and ligaments. This PhD
project will further develop the prototype by increasing the bioactivity and
enhance the integration of the constituent material with the surrounding
tissues, and will bring this technical solution towards clinical application.
The following aspects will be investigated: optimization of the
polymeric biomaterial and its functionalization to improve cell adhesion,
recruiting and differentiation and to prevent inflammatory response, optimal
technique for effective sterilization; means of surgical attachment to the host tissue.
The collaboration between the
technical area (engineering and chemistry) with the clinical counterpart
(orthopaedic surgery) will be a key point of this project.
Objectives of this
project
The overall objective of this PhD project to bring a promising electrospun scaffold
for the repair of tendons and ligaments from the current state of technical
development (between TRL3 and 4) towards clinical application. The following specific objectives will be
tackled:
Optimization of
the sterilization technique to ensure effective sterilization of the
nanofibrous structure and preservation of the desired mechanical properties and
biocompatibility properties
Optimization of
the surgical technique to attach the scaffold to the host bone, and/or the
residual tendon/ligament, in collaboration with the orthopaedic surgeons to
ensure adequate mechanical strength and lack of stress concentrations and
surgical practicability
Increasing
scaffold bioactivity and integration in the surrounding tissues to prevent
adverse response of host tissue and avoid inflammatory reactions.
This project covers some basic science (interaction between nanofibrous
scaffold and host tissue), it focuses on technological development
(implementing and testing different solutions on the scaffold) and has clinical
relevance (develop the best solution for implantation).
Rationale and scientific background
The fact that different orthopaedic surgeons chose different strategies
for the repair of damaged tendons and ligaments is an indicator that there is
no consolidated and satisfactory technique.
In fact, the post-operative outcome is far from satisfactory. Surgical treatments fail in 15% and 40% of
cases (depending on the initial indications).
Artificial implants fail mostly because of biomechanical mismatch
(inadequate stiffness, limited strength etc).
Xenografts often do not get properly integrated or even create
rejection. Allografts offer better
similarity, but are limited due to cost and availability. Autografts solve some of the problems above,
but are associated with morbidity of the donor site and are limited in stock.
Bioresorbable scaffolds are a very promising option, as they are not
limited in availability [1]. We recently
developed a technique to manufacture electrospun scaffolds that replicate the
morphology and the mechanical properties of the human natural tendons and
ligaments [2,3].
To bring this project towards an animal trial and a future clinical
application, there are some clear points that need to be fine-tuned. Specifically, as the key to success of such
devices is integration with the host tissues, this project aims to understand
how to prevent such common clinical complications, and to develop the
extremities and the interfaces so as to grant success in case of implantation.

Research project
The focus of the activities will be on optimizing and
testing electrospun hierarchical scaffolds made of blends of natural (collagen)
and synthetic (PLLA) polymers so as to ensure that they become suitable for
implantation. This PhD candidate will
spend 30-40% of his/her time in the biomechanical laboratory of prof.
Cristofolini, 30-40% of the time in the Chemistry lab of prof. Focarete and the
remaining 20-40% of in the clinical settlement, in collaboration with Rizzoli
Orthopaedic Institute. Furthermore, an
international secondment of 2+3 months at the University of Portsmouth is
planned to complement the preparation of this candidate providing
high-resolution imaging and cell culture, whereas an international secondment
of 2+3 months at Erlangen University is planned to complement the preparation
of this candidate on scaffold functionalization and biomineralization.
Activity 1 – CLINICAL TRAINING. Building the
understanding of lesions of the tendons and ligament, about the current
surgical techniques for reconstruction, and about the post-op failure
mechanisms. This activity will be
particularly intense during the 1st year, to acquire new clinical
understanding. However, during the
entire duration of development and validation activities will be closely
connected to the clinical environment.
Activity 2 – STERILIZATION TECHNIQUE.
Within this activity the candidate will first get familiar with the
sterilization techniques that can be applied to this family of resorbable
materials. Tests will be carried out to
identify a technique and the parameters that grant adequate reduction of the
bioburden, without compromising the mechanical properties and the biocompatibility
of the scaffolds
Activity 3 –SCAFFOLD BIOACTIVITY AND INTEGRATION WITH HOST TISSUE. This activity will be carried out in parallel
with the previous ones, with the aim to optimize the constituent material and
increase the bioactivity of the scaffold and its integration with the surrounding
tissues. Within this activity the
candidate will get familiar with scaffold functionalization techniques.
Activity 4 – BONE INSERTIONS. The
activities within this activity are fundamental to adapt the scaffolds and
define the surgical technique that will provide adequate insertion in the host
bone. This is currently one of the main
surgical challenges. The input of the
clinical supervisor is extremely important in this phase.
Innovation potential
This proposal mainly aims at technological innovation: this PhD project
will provide significant advancement in the development and validation of
nanofibrous scaffolds. In particular,
currently no hierarchical scaffold is available for the regeneration of tendons
and ligaments. This research will deliver
unpreceded solution with highly biomimetic scaffolds. The main points of innovation will be:
Advancing
the development of electrospun hierarchical bioresorbable scaffold
Developing
and validating technological and surgical solutions for the attachment of such
scaffolds to the host tissues
Developing
and testing innovative solutions to prevent inflammatory response and tissue
adhesion
Furthermore, it is foreseen that this project will deliver scientific
innovation providing new insights in the way host tissues (tendon, ligament,
bone and enthesis) react to nanofibrous scaffolds
Expected results and applications to human pathology
and therapy
This project is meant to develop a better solution for the repair and
regeneration of lesions of tendon and ligaments, so as to overcome the critical
limitations of the current commercial devices and surgical techniques. This will allow, in a perspective, to deliver
better treatments both to young patients (typically affected by traumatic
lesions) and elderly ones (presenting degenerative lesions).
While in the duration of this PhD project it is not realistic to start a
clinical trial on humans, it will definitely open the way to a dedicated animal
trial.
The research team
This candidate will have an engineering
background. While this will facilitate
him/her in grasping the technical part of the project, some time and effort
must be dedicated at the beginning to improve his/her understanding of the
clinical problem. This
project is rooted between three groups:

the first prototype of this implantable scaffold. The success of collaboration is documented by
a number of joint publications. Also:
Prof. Traina and prof. Cristofolini have been intensively collaborating for
years on research projects at the intersection between orthopaedic clinical
application and biomechanics research. A
strong integration of the two research groups has been achieved by involving the
clinical staff in lab activity, and the lab staff in clinical research. This PhD candidate will enjoy this extremely
stimulating interdisciplinary environment, and will share his/her research time
between clinics (in tight collaboration with Rizzoli Orthopaedic Institute) and
biomechanics lab.
The Polymer Science and Biomaterials group at the
Chemistry Department “Ciamician”, UNIBO has recognized expertise on structure-polymer correlation of natural and
synthetic polymeric biomaterials. The group has strong knowledge of material
design, material processing through conventional and advanced innovative
technologies and nanotechnologies, material characterization and study of
biodegradability. The group has demonstrated the capability to develop
polymeric systems for drug delivery and as tissue models for tissue
engineering. In collaboration with the Biomechanics lab of prof. Cristofolini the group has
acquired knowledge to develop scaffolds with optimized biomechanical properties
by playing on the choice of the more appropriate material and on the selection
of the best morphological properties of the scaffolds.
The Biomechanics group is directed by prof Luca Cristofolini and prof
Marco Viceconti and is part of the Department
of Industrial Engineering. The group
has been active for almost 30 years in the area of musculoskeletal
biomechanics. The environment is
informal and friendly, and collaborations are encouraged between team members,
and between juniors and seniors. The
biomechanics group is formed by Italian and International young scientists, and
has strong ties with the clinics (e.g. Rizzoli Orthopaedic Hospital), with
international partners (as part of collaborative projects), and with the
industry (e.g. orthopaedic manufacturers, software developers). The focus of the
group directed by prof. Cristofolini is on the multi-scale biomechanical
characterization of skeletal structures and orthopaedic devices, and on the
integration of in vitro tests and
numerical modeling. Their main
activities focus on preclinical testing of orthopaedic implantable devices, and
validation of innovative surgical techniques.
Their group, in collaboration with the Electrospinning group, recently
developed and characterized innovative regenerative scaffolds. Furthermore, this group is acknowledged
internationally for the applications of DIC to biomechanics.
The Dept. of Orthopaedic-Traumatology and Prosthetic surgery and
revisions of hip and knee implants of the Rizzoli Orthopaedic Institute is
nationally recognized for the treatment of severe orthopaedic conditions
including joints tendon and ligament reconstructions (mainly in the lower
limb). Its activity is mainly focused on
surgical treatment of complex cases, analysis and data collection of multiple
type of joint replacement surgery through different surgical approach and
procedures. Comparison between different
procedures and cases are routinely performed in order to continuously improve
the patient’s provision of care.

PhD PROJECT #2:
Patient-Specific Spinal Surgery for Severe Scoliosis
(PS5)
Summary
Scoliosis can be extremely
threatening: pain, disability, compression of internal organs, breathing
problems are just some of the consequences. In the most severe cases,
corrective spinal surgery is the only viable option. In young and growing patients, adjustable
devices must be used, that are mobilized over the months to correct the spine
and follow the patient’s growth. One main challenge for the clinical
specialist is to choose the optimal treatment for each patient, for example how
to plan the right amount of adjustment over time, so as to achieve the desired
correction while avoiding complications and adverse effects. Currently, surgeons are guided only by
intuition and experience. The aim of
this PhD project is to develop and validate a modelling technology capable of
generating patient-specific predictive models of the spine biomechanics that
can be used as a treatment planning tools, by simulating different treatment
options and predict the occurrence of adverse effects including spinal cord
compression, facets impingement, excessive strain of the intervertebral discs,
excessive stretch of the muscles.
Objectives of this
project
The project aims to develop a
treatment simulation environment to optimise the treatment of scoliosis
patients. The research will articulate in the following phases:
Collection of dedicated biomechanical information
(stiffness of discs and ligaments, range of motion) through ex vivo testing of spine specimens.
Development of the
protocol to build patient-specific computer models of the spine biomechanics
from medical imaging data (CT, MRI and X-ray).
Use of the ex vivo experimental data to quantify
the model predictive accuracy.
Develop a
treatment simulation environment, where the most common interventions are
properly simulated, and adverse effects (if any) predicted.
Use retrospective
clinical data to establish the clinical accuracy of treatment simulation
environment when compared with the actual outcome of a specific treatment in a
given patient.
Through these
activities, the PhD student will gain skills in the area of biomechanics, in
silico modelling, and orthopaedics (spine)that will make him/her employable in
the academia, but also in device manufacturers and developer of medical
software.
Rationale and scientific background
Congenital and idiopathic scoliosis can be extremely threatening when
causing severe deformity. Pain,
disability, compression of internal organs, breathing and cardiac problems are
just some of the consequences.
Corrective surgery is the only option in extreme cases: this consists in
the implantation of screws (or hooks) and rods that restore alignment in the
frontal and sagittal planes. The surgeon
must find a compromise between extreme correction (ideally restoring “perfect”
anatomy) and avoiding damage due to compression or stretching of the spinal
cord or nerves. In young patients, an
additional challenge derives from the changes over time due to growth. In these cases, the surgeon can use Magnetically
Controlled Growing Rods that must be mobilized at time intervals to induce
progressive correction and allow natural lengthening. Currently, no evidence-based tool is
available to help the surgeon plan the optimal compromise. Surgeons can only follow their experience
and, to some extent, a trial-and-correct approach [1]. This clearly exposes the patient to the risk
of unnecessary pain, organ damage, and sub-optimal correction.

Research project
The focus of the activities will be on developing a
numerical model of the growing spine while undergoing correction. This PhD candidate will spend 60-70% of
his/her time in the biomechanical laboratory developing in vitro tests (supervisor L. Cristofolini) and numerical models
(supervisor M. Viceconti), 30-40% of the time in the clinical settlement
(Rizzoli Orthopaedic Institute) collecting and analysing retrospective patient
cases. Furthermore, an international
secondment of 4-5 months at a foreign clinical institution (for example, the Buda
National Center for Spinal Disorders led by Prof Peter Paul Varga, in
Budapest), preliminary step to develop a full scale multicentric clinical trial
for the new technology after the end of the PhD project.
WP1 – BASIC CLINICAL
TRAINING. Building the understanding of
spinal deformity, surgical corrections, short-and long-term outcomes and
complications. This WP will be particularly intense during the 1st
year, to acquire new clinical understanding.
However, during the entire duration of development and validation
activities will be closely connected to the clinical environment.
WP2 – COLLECTION OF EX VIVO DATA. Within this WP the candidate will collect a
set of biomechanical data from cadaveric spines from young donors. This will serve to initialize the models and
identify the relevant parameters (WP3 and 3)
WP3 – PROTOCOL FOR
PATIENT-SPECIFIC MODELLING. This will
include the Development of the modelling protocol on retrospective data and the
Development of ad hoc imaging protocols.
WP4 – EX VIVO
VALIDATION OF PREDICTIVE MODELS. The
candidate will use the experimental data collected in WP2, and the modelling
protocol developed in WP3, to develop predictive models of the ex vivo
experiments form CT data of the specimens and validate the modelling protocol
by comparing the model predictions to the experimental measurements.
WP5 – DEVELOP
TREATMENT SIMULATION ENVIRONMENT. Once
the model is fully validated ex vivo,
the candidate will develop the simulation of the various interventions
available.
Innovation potential
There is an acute unmet need for proper planning tools in the treatment
of sever scoliosis. While the biomechanics of the scoliotic spine is complex,
in the last 20 years a massive amount of experimental and modelling work has
been done, which can be capitalised here. We thus believe there is a significant
innovation potential in this project. If
reasonable predictive accuracies are achieved, after the end of the project we
will explore the possibility to hand over the technology to a company, or to
establish an exploitation team without our group. In both cases, a multicentric clinical trial
will be required to demonstrate the efficacy of this new technology when
compared to the current standard of care.
Meanwhile we will work to establish a planning service for Dr Greggi
clinic, and for any other spine surgeon at the Rizzoli Institute, who is
interested in using this technology to plan their interventions.
Expected results and applications to human pathology
and therapy
In this case, the clinical impact is self-explanatory: if the technology
works as expected, and provide sufficient accuracy to be clinically
informative, this could radically change the standard of care for the handling
of sever scoliosis cases.

PhD PROJECT #3:
Innovative technique
to repair osteoporotic fractures with bone substitutes
Summary
The second most common site for
traumatic fracture in the elderly is the upper limb (proximal humerus and
distal radius). Reconstruction of these
fractures is currently performed with plates and screws. In both cases, healing failures (mainly
pseudo-arthrosis) derive from lack of stabilization of the bone fragments,
which is particularly frequent in case of poor bone quality and osteoporotic
defects. As the current technique is
dissatisfactory (adding more screws would not solve the problem) we will
explore a different approach. A bone
substitute will be used in combination or in replacement of plates and screws. This PhD project consists of three main
actions: (i) biomechanical testing of different reconstruction techniques to
identify the optimal ones; (ii) definition of surgical guidelines based on ex
vivo fluoroscopic imaging (similar to the foreseen surgical protocol), in
relation to biomechanical performance; (iii) definition and following of
clinical trial on selected fracture cases.
This project originated from the
clinical problem encountered by orthopaedic surgeons, will require significant
input from the technical area, and will rely on collaboration with a biomedical
company.
Objectives of this
project
This PhD project addresses a clinical objective:
developing and validating an alternative technique for the treatment of
osteoporotic fractures of the upper limb.
This project will start from preclinical in vitro testing, and will finally reach the first stages of
clinical trial. The following specific
aims will be targeted:
Adapting the
surgical technique through in vitro tests
and biomechanical simulations. This will
allow to define the biomechanical criteria for the use of the bone substitute,
and will confirm which of the traditional osteosynthesis components can be
avoided.
Definition of the
surgical guidelines to indicate the surgeon the optimal amount of bone
substitute to be delivered in each patient under safe conditions. This part will integrate imaging techniques
with biomechanical testing, so as to confirm the conditions to be achieved
during surgery to grant optimal strength of the reconstruction.
Testing the
concept through a first clinical trial so as to provide clinical evidence about
the safety and efficacy of this technique.
Rationale and scientific background
Proximal humeral and distal radial fractures account
for about 25% of all fractures in the elderly and affecting approximately 142
out of 10,000 persons per year [1].
Locking plate fixation is considered the optimal treatment for these
fractures, when possible. Incidence of
complications increases according to patient’s age, number of fragments,
fracture pattern and dislocation [2].
Intra-operative risks of this technique include articular cartilage
damage while drilling or inserting the screws [3]. This risk is increased as the surgeon may
need to use multiple screws to stabilize the different fragments, since in
osteoporotic setting the screws must be long enough to achieve fixation in the
subchondral bone. The most common
post-operative failure mechanism of plated proximal humeral fractures is a
secondary loss of reduction [3]. Low
bone mineral density (BMD) is the primary cause of this complication. In fact, one of the most common mechanisms of
failure is a sliding of the fragment: osteoporotic bone has a weak mechanical
structure, and repetitive loading damages the cancellous bone because of the
high stress at the tips and threads of the screws.
In these fractures it is important to obtain immediate
post-operative fixation strength, to early mobilize the shoulder and prevent
post-operative stiffness. To reduce the
incidence of mechanical failure, several augmentation techniques have been
developed. While augmentation provides
some improvements, it also has different specific drawbacks [3]. Recently some innovative products have been
released, with the aim of conjugating the positive aspects of the different
augmenting materials. In particular the
biomaterial used for this study is a combination of beta-TCP (beta-tricalcium
phosphate) and polymethylmethacrylate (PMMA), aiming to provide good initial
mechanical property, and bone ingrowth with partial substitution over time [4].
Therefore, to improve the reconstruction technique for
such fractures, alternative techniques are being sought. Rather than increasing the number of screws,
the focus is shifting towards bone substitutes as means of initial fixation,
and to promote bone healing [5]. The
trauma surgeons in Rizzoli area are among the pioneers in this field.

Research project
This project aims at bringing towards the clinical
trial a treatment solution that currently has been exploratively tested in vitro. This PhD project will start with training of
the candidate (which must have a technical background) on the clinical problem
(WP1). The candidate will then spend
60-70% of his/her time in the biomechanical laboratory of prof. Cristofolini
developing and testing the treatments solutions (WP2 and 3). Finally, he/she will spend the remaining time
in the Rizzoli Orthopaedic Institute, analysing the results from the clinical
trial.
WP1 – CLINICAL TRAINING. The
candidate first will need to get familiar with the types of fracture, treatment
options, and failure scenarios. This
activity will be particularly intense during the 1st year, to
acquire new clinical understanding.
However, during the entire duration of development and validation
activities will be closely connected to the clinical environment.
WP2 – BIOMECHANICAL OPTIMIZATION OF REPAIR TECHNIQUE. This part of the project will explore
different treatment options aiming to reduce/avoid the use of screws and plates
in osteoporotic fractures of the upper limb, and to assess the biomechanical
influence of using a bone substitute. The
core of this WP is a series of biomechanical in vitro tests on cadaveric bone specimens.
WP3 – DEFINITION OF SURGICAL GUIDELINES.
While WP2 concentrates on biomechanical optimization, this WP aims to
identify the optimal indications for actual clinical implementation. The optimal types of reconstruction for the
humerus and radius (not necessarily the same) will be addressed. Reconstructions will again be performed on
cadaveric specimens, but using instrumentation and imaging as in real surgery,
to define the ideal protocol.
WP4 – CLINICAL TRIAL. The best
solutions (from WP2) will be applied to fracture patients following the
guidelines (from WP3). Preliminary
approval by the ethical committee and the relevant authorities has already been
submitted for an initial clinical trial.
Innovation potential
This PhD student, in collaboration with the
orthopaedic surgeons involved and the biomechanical group, will develop and
assess a new solution for treating osteoporotic fractures. The combined use of an osteoconductive
injectable bone substitute and classic screws, and the use of such bone
substitute are a new concept for the treatment of this type of fractures. This project will therefore lead to
technological innovation in the delivery and use of such cement (possibly
requiring further development of the bone substitute itself, in collaboration
with the Manufacturer).
Expected results and applications to human pathology
and therapy
This project will develop and validate better
treatments for osteoporotic fractures of the upper limb, that are currently
difficult to treat, and have unacceptably high failure rate. It is expected that the innovative solutions
proposed will improve fracture treatment in different ways:
Lower incidence of
articular damage due to intra-op cartilage drill-in
Lower incidence of
short- and mid-term failures (pseudarthrosis, malunions)
Better bone
healing thanks to the osteoconductive bone substitute.
