The new digital life of a drug

The cost of successfully bringing a new drug to market has never been higher.

Research has shown that the average cost amounts to $1.3 billion USD¹. The process is also lengthy, often taking more than ten years to bring a research lab discovery to Food & Drug Administration (FDA) approval, and eventually into patients’ hands. Yet, only 10% of the drugs that start pre-clinical trials ever make it to the end.2 According to a research done by Deloitte, return on new drug research & development (R&D) has fallen from 10.1% in 2010 to 1.9% in 2019.3 FDA approved 53 novel drugs in 2020, the second highest count in over 20 years, contrasting with over 123,000 trials currently ongoing in the US.4

Even after a successful launch, getting the right drug into the hands of the right patient is not as straightforward as one might think, often complicated by the patient’s insurance coverage (or the lack of), co-pay program, the doctor’s awareness of the drug, etc. Pharma representatives, whose mission is to educate doctors about novel drugs, spend most of their time travelling and trying to catch doctors face-to-face in between their patient appointments. These meetings last on average only three minutes, just allowing sales reps to drop off samples and a few printed paper brochures.5 How to be effective in these three minutes is a big challenge.

This [connecting sites, patients and sponsors using Veeva Clinical Network] is a bold vision for the industry that over time has the potential to make [clinical] trials 25% faster at 25% less cost.

Then medication non-adherence has persisted as a serious problem as it affects treatment success, leads to worsening of disease, and increased healthcare cost. Some call it “the silent killer”. Extensive research has shown that even in developed countries, adherence to therapies averages only 50%, whereas half of the non-adherences being intentional.6 Adherence rates are typically lower among chronic disease patients compared to patients with acute conditions.

We are seeing innovation accelerating across the different stages of drug development (see picture 1). AI and machine learning have just started to show their potential as powerful tools and possibilities seem to be endless. Some of them might transform biology and healthcare for good.

Computational R&D redefining drug discovery

Traditional drug discovery process relies on many reiterations of trial-and-error. It is labor intensive, inefficient, slow, and prone to high failure rates. It often takes years and millions of dollars just to identify a target and validate a “hit compound” – a molecule that shows the desired activity in a screening assay, which could potentially be turned into a drug.

Computational R&D companies look to improve this process by offering simulation tools that allow scientists to predict drug properties and design new drugs using models, the same way that virtual plane engines are designed and simulated before being prototyped on the factory floor. This could greatly reduce the time it takes to develop the drug and at the same time improve the quality of the final drug.

One example was the gigantic leap of Alphabet DeepMind’s AlphaFold, which uses deep learning to predict the 3D structure of proteins at high accuracy.7 Some believe it will transform biology. Google’s AI has also shown great potential of outperforming radiologists in lung cancer and mammographic screening based on CT scanner images.8

Last year, together with partner Eli Lilly, Abcellera, a next-generation therapeutic antibody discovery company, brought to life the first antibody treatment Bamlanivimab, developed for COVID-19 pandemic in only nine months.9 Abcellera screens the diversity of the human immune system for antibody discovery, incorporating microfluids, single-cell analysis, high-throughput genomics, machine learning and hyper-scale data sciences. It took Abcellera only 90 days from receiving the COVID-19 antibody sample from a recovered patient to the phase of human testing. Bamlanivimab received FDA emergency use authorization in November 2020.

Another company Recursion Pharmaceuticals utilizes machine learning, big data computational tools, lab robotics and databases to analyze potential chemical interactions of derived images of proteins. It aims to broaden the breadth of potential starting points and identify failures earlier in the drug discovery process.  

Pressure to eliminate animal testing is another driver of using computational simulation. In 2019, the US Environmental Protection Agency (EPA) committed itself to reduce its funding request for animal studies by 30% by 2025 and phase them out entirely by 2035.10

Leaner and less costly clinical trials

Clinical trials typically consume half of the entire drug development cost, whose total spend often adds up to over $1bn as mentioned above. Figure 1 shows the rough breakdown of various costs:

Among the causes of trial failures, most cited reasons include failure to recruit enough eligible patients, mid-trial patient drop out, side effects and inconsistent data. Patient recruitment is also the most common reason of trial delay with nearly 80% of the trials failing to finish on time due to lack of enrolees. A study showed that only 3% of the cancer patients in the US are enrolled in clinical trials.12

On the other side, potentially eligible patients struggle to find the trial that suits them. Using online marketing as an analogy, there is no such thing as “personalized targeting” that allows the advertiser to target precisely the relevant consumers. Typically, a patient’s journey starts with browsing on clinicaltrial.gov which records all the currently ongoing clinical trials in the US. At any time, more than 20,000 clinical studies are recruiting patients. Occasionally, the patient’s physician can recommend a trial provided that he is aware of it. 

Then the patient often needs to take on the burden of trial application himself. There is no centralized repository of patient medical data. Clinical data is often scattered across different doctors the patient has visited, which is stored on different electronic health record (EHR) systems with no interoperability between them. Some documents are sent by fax or scanned hand-written copies which are prone to error. It often takes the patient a substantial amount of time and effort to gather all the clinical information needed to apply for the trial and yet, only 30% would meet the enrolment criteria.13 Under the Health Insurance Portability and Accountability Act (HIPAA), data sharing is now allowed with patient’s authorization, but the lack of system interoperability and related data security issues still makes it a cumbersome process for patients.

Once the patient is enrolled in the trial, it can last as long as six to seven years. Patients are asked to keep their physiological data diary, which is still often paper-based, prone to human error, and overly reliant on patient memory. Then patients need to travel to the participating site regularly and share these data with site researchers with a various degree of time delay. This burdensome and inconvenient process leads to an average of 30% patient dropout rate.14

The need of remote patient monitoring is even more pronounced in novel technologies such as gene and cell therapies. These clinical trials need less patients, often only a dozen, but will need longer follow-up period, which offers a good use case for remote monitoring devices as a means to reduce burden on patients.

Veeva Systems is a software company developing applications for life science industry. It offers a suite of applications that span the full drug development lifecycle. Its Vault platform unifies clinical, regulatory, quality and safety functions in drug development process. As CEO Peter Gassner shared on its Investor day in 2020:

We have a full vision to change the way trials are executed. We want to make clinical trials paperless and patient-centric.

As a result, we believe significant opportunities are untackled in optimizing trial design, patient recruiting, electronic data collection, regulatory approval and patient adherence using technologies such as big data analysis, AI, remote device monitoring, which ultimately would help clinical trials to recruit the right patient at lower cost and in the mean time offer a more patient-friendly experience.

Drug commercialization moving online

A study has found that almost 20% of big pharma company revenues go to marketing and advertising – this represents a total spending of $50bn just for the ten largest drug makers in the U.S.15 A substantial portion of the spending goes to the pharma sales reps, whose mission is to educate the healthcare professionals about the drugs. There are 81,000 pharma sales reps in the US reaching out to about 830,000 doctors.16

Despite tools such as CRM (Customer Relationship Management) that allows life science sales reps to manage, track and optimize their interactions with healthcare professionals, offline face-to-face visits remain the primary form of contact as of today. The COVID-19 pandemic democratized the adoption of virtual visits, as people were confined at home. Interestingly, doctors have shown high satisfaction towards the virtual format, along with increased productivity of sales reps. Veeva found that virtual meetings last between 10 and 40 minutes, significantly higher than the three minutes face-to-face ones.17 Some speculate that the increase in productivity will allow pharma companies to reduce sales reps headcount and that digital marketing will continue to grow after the pandemic.

In a survey conducted by M3 – a leading doctor network operator in Japan – in July 2020, “75% of physicians prefer current condition of higher [more extensive] digital information procurement”, which prompted M3 to think that this shift in behavior and sentiment is likely to remain.18

Novel solutions for patient adherence

Studies have shown that 20-30% of drug prescriptions are never filled in the US, and that approximately 50 percent of medications for chronic disease are not taken as prescribed. This lack of adherence, is estimated to “cause approximately 125,000 deaths and at least 10 percent of hospitalizations, and to cost the American health care system between $100 billion and $289 billion a year.” 19

Fulfilment non-adherence is often attributed to lack of insurance coverage and high deductibles or high co-pay. Other factors of non-adherence include non-persistence and non-conformation. Some are intentional while some others are not. But in either case, better communication between the physician and the patient and using technology to facilitate the process would prove to be beneficiary.

Some companies such as OptimizeRx are looking for innovative ways to address this issue, trying to reach out to potential patients directly, improve patient drug adherence and build their own database. This could be particularly valuable for other stakeholders such as FDA and pharma companies who are increasingly interested in RWE (Real World Evidence) as a supplementary of RCT (Randomized Controlled Trials)20.

Can you imagine spending billions of dollars on developing a drug and not being able to communicate or educate [physicians and patients] … on its clinical benefit, cost, and adherence?
