A 2026 mama health analysis

A new way to map the patient journey is
reshaping launch performance.

Across recent commercial launches, the gap between the 40% that beat forecast and the 60% that miss it comes down to a small set of decisions made early. Our 2026 analysis examined what the winners do differently — and why patient understanding sits at the center of it.

Section 01 · The launch gap
Launch performance × commercial reality

Most launches miss forecast. Few beat it.

Industry analyses from McKinsey, Deloitte, EvaluatePharma, and IQVIA consistently put the drug launch failure rate at around 60%. Only 25% meet forecast. Just 15% exceed it.

Pharmaceutical companies spend between $475 and $830 million per launch on commercial activities — market access planning, field force training, medical education, patient support, and omnichannel engagement. With that level of capital deployed before any revenue is realized, an underperforming launch puts hundreds of millions at risk.

Clinical success does not guarantee commercial success. The question every launch leader is asking: what does the 40% that beats forecast do differently?

How mama health closes this gap

We give commercial teams the patient evidence they need before launch decisions get made.

A continuously updated view of the patient journey — built from thousands of real patients, structured by AI, and refreshed as treatment, diagnosis, and patient expectations evolve. Launch teams plan against the patient reality that exists, not the one they assumed.

The five root causes

Launch underperformance is commercial, not scientific.

Across recent commercial launches, five drivers emerged consistently. Only one of them has anything to do with the drug itself.

// Driver 01
30%
Market access barriers — payer coverage and reimbursement friction.
// Driver 03
26%
Weak differentiation — uptake lost in crowded therapeutic categories.
// Driver 04
13%
Stakeholder misalignment — commercial, medical, and access teams out of sync.
// Driver 05
4%
External factors — pandemic, supply, regulatory shocks outside team control.
// Patient insight gap
Driver 02 27% of failures

Patient insight gaps account for 27% of launch failures — second only to market access.

Section 02 · The patient gap
Commercial assumptions × patient reality

The launches that beat forecast see the patient before the market does.

Launch teams that miss forecast almost always describe the same problem in hindsight: the patient they planned for wasn't the patient who showed up. Diagnosis was harder than expected. Side effects were worse. Adherence was lower. The patient journey map informing the launch reflected a reality that had already moved on.

Launches that exceed forecast share a different pattern. Their commercial teams worked from a continuously updated view of the patient journey — built from real patient data rather than periodic research — and they planned against the patient reality that actually existed at launch.

The methodology shift sounds incremental. The operational shift across commercial, medical, and access functions is not.

How mama health closes this gap

Continuous patient evidence, not periodic research.

Thousands of real patient conversations, structured by AI into a live view of symptoms, diagnosis delays, treatment hesitation, switching, side effects, and adherence. Every stage of the patient journey, KPI'd. Commercial, medical, and access teams plan against the same evidence — refreshed as the reality moves.

Case studies from the report

The gap between forecast and reality, in dollars.

Three of the most-studied launch failures of the past decade. In every case, the clinical data was strong. The patient understanding wasn't.

Aduhelm
Alzheimer's · 2021
$3M
Actual · 6 months
vs
$3B projected
Analyst expectation

Medicare restricted coverage. Doctors were unconvinced by mixed clinical data. High out-of-pocket costs and burdensome monitoring meant few patients could start therapy. Every root cause hit at once.

Actual · Q1 2019

Forecast

Severe diarrhea drove high discontinuation rates. Oncologists were unprepared to manage the side effect. The post-prescription journey was never mapped — and patients hit an adherence barrier the launch plan didn't address.

PCSK9 inhibitors

Pre-launch forecast

$14,000 annual price tag prompted strict prior authorization. Over 30% of patients prescribed discontinued therapy due to payer refusals. Access barriers killed uptake before patient experience could catch up.

From single-market pilot to multi-country scale, every engagement follows the same shape. Pilot in one market. Validate the journey against real patient evidence. Scale across the portfolio. Built for launch teams under pressure to act.

What the 40% does differently

The launches that beat forecast share three habits.

Across the launches that meet or exceed forecast, three operational practices show up consistently. None require a different drug. All require a different relationship with patient evidence.

Start market access planning earlier

Don't wait until approval to address payer concerns. Engage payers in parallel with clinical development. Ground value narratives in patient-reported outcomes. Limited access drives 30% of failures — excelling here is the single largest performance lever.

Align cross-functional teams around one patient view

Commercial, medical, access, and HEOR teams build strategy from the same continuously updated view of the patient. Conflicting narratives close. Trade-offs get easier. The patient journey becomes shared ground truth, not a deliverable owned by one team.

Invest in deep patient insight and journey mapping

Map the patient journey continuously — symptom onset, diagnosis, access barriers, treatment initiation, side effects, adherence, switching. Lack of patient insight drives 27% of failures. The launches that win operate on what patients are actually experiencing, refreshed in near real time.

The patient journey isn't a slide.
It's infrastructure.

The launches beating forecast are the ones treating it that way — built on continuous patient evidence, refreshed in real time, planned against across every commercial function.
