Clozapine History

Clozapine is a second-generation antipsychotic used for treatment-resistant schizophrenia. Since its discovery in 1958, it has emerged as the sole FDA-approved therapy for treatment-resistant schizophrenia. Yet, its troubled history and gaps of knowledge have continued to prevent its effective use and contributed to its underutilization. In 1975, clozapine was banned in the United States due to reports in Finland describing rates of agranulocytosis of 0.05 to 2%. These were higher than rates among patients who had received standard psychotropic medications and led to a series of deaths (Idänpään-Heikkilä et al., 1975). As a result, the use of clozapine in the U.S. and further drug development was abruptly halted. Per clinical observations, particularly at Zucker Hillside Hospital (ZHH) where there were many hospitalized patients on clozapine, patients with a true diagnosis of schizophrenia had a very difficult time being weaned off due to psychotic decompensation and, when put back on clozapine, staff observed dramatic improvements in clinical status. Research led by John Kane, M.D. at ZHH designed what turned out to be a landmark study, leading clozapine to receive FDA approval in 1990 (Kane et al., 1988).

Underutilization Of Clozapine

Despite being the only FDA-approved medication for treatment-resistant schizophrenia, with fatality from agranulocytosis now being very rare, it remains underutilized. It is estimated that 30% of patients with schizophrenia are treatment resistant, but the utilization rate of clozapine in the U.S. is under 10% (Stroup et al., 2014). Furthermore, it is estimated that 20% of first-episode patients are treatment resistant, yet many do not receive clozapine despite this being a critical time to get the illness under control and optimize long-term outcomes (Demjaha et al., 2017; Lally et al., 2016; Kanahara et al., 2018).

In fact, research has shown that there is a case to be made for clozapine being used after the failure of one antipsychotic rather than two (Kahn et al., 2018). Clozapine is associated with lower rates of long-term hospitalizations, despite greater illness severity of patients who tend to receive it (Masuda et al., 2019). A 20‐year follow‐up study of physical morbidity and mortality in relationship to antipsychotic treatment in a nationwide cohort of 62,250 patients with schizophrenia suggested that long‐term antipsychotic use does not increase severe physical morbidity leading to hospitalization, and is associated with substantially decreased mortality, especially among patients treated with clozapine (Taipale et al., 2020).

Tips For Counseling Patients And Families On Clozapine

In addition to presenting benefits and risks, it is important to share success stories.

There are many stories of subsets of clozapine responders for whom the medication was life-changing in dramatically positive ways.

Like we do with many treatments in medicine, start with benefits and then move on to the risks.

Many clinicians will be anxious to convey all of the different and unique risks that clozapine carries, which is important, but often dominates the conversation in a way that is driven by the clinician.
Patients deserve to know the high potential upside.

Recommend an adequate trial as a measure of whether to stay on it for a longer period.

Advise an initial 3- to 4-month trial to get a good sense of how life could be different and how the changes in symptoms and functional outcomes weigh against the side effects. Then, patients can make a more educated decision about a medication that could potentially be life-changing, rather than not trying it at all.

Long-Acting Injectables

Like clozapine, the long-acting injectables (LAIs) are highly underutilized despite being available for many years. They are often viewed as a hassle to use with more work for the clinician. Explaining the benefits and also discussing the risks with patients who initially may be reluctant takes effective training, time, and practice, but when done well can be effective at improving LAI use. An intervention that enacted training sessions with staff of multiple clinics helped to get LAI acceptance rate as high as 86% (Kane et al., 2020). Studies show that across all fields of medicine, about 50% of patients take medications as prescribed (Chaudri 2004).

In psychiatry, we are fortunate to have tools like LAI’s that other fields of medicine do not have, and given the data that shows multiple benefits to LAI use, including increased time to rehospitalization, it makes sense to be offering these tools to patients earlier and more often (Kane et al., 2020). Additionally, LAIs have an important connection to clozapine, in that trialing an LAI before starting clozapine ensures adherence, helping to establish true treatment resistance. Patients are often labeled as treatment resistant when their decompensation is actually due to treatment nonadherence (McCutcheon et al., 2018).

Tips for Counseling Patients on LAIs

Self-reflect on biased ideas we may have internalized regarding LAIs.

Often, psychiatrists wait to offer LAIs to patients who “prove” they are “noncompliant” or who are “bad patients” or “aggressive.”
These views foster negativity toward LAIs and deprive patients of opportunities to use effective treatments.
This kind of language is often racially coded with bias against black and brown populations.

Be mindful of prior trauma associated with injections.

Patients will likely recall traumatizing experiences of being administered injections against their will in the hospital during episodes of agitation.
Differentiate between emergency short-acting injections given involuntarily versus long-acting injections which are a treatment option that can help foster independence and decrease the risk of hospitalization.

Introduce the idea of LAIs early in the treatment course in order to help normalize them as part of the standard of care treatment.

Patients should be informed early in treatment that the recommended course is establishing efficacy and tolerability on oral medication, and then transitioning to an LAI.
The LAI should be presented as a unique tool in psychiatry that we are fortunate to be able to offer.

Recovery Model And Coordinated Specialty Care

The Recovery Model takes a stance of optimism about outcome from serious mental illness and focuses on empowerment, shared decision making, and helping clients find productive roles in line with their goals (Warner 2010). It decenters symptoms and treatment response as a sole focus and gives patients the dignity and autonomy to focus on what outcomes are most important to them. This allows for the dignity of risk and the dignity of going through a learning process if a decision that a patient makes does not end up working out as originally anticipated. The Recovery Model approach is closely tied to the practice of Coordinated Specialty Care (CSC) in the treatment of First Episode Psychosis (FEP). CSC consists of interventions including assertive case management, individual or group psychotherapy, supported employment and education services, family education and support, and low doses of select antipsychotic agents. The CSC framework for FEP is similar to the Assertive Community Treatment (ACT) model, but in contrast to ACT, CSC serves a younger population without established disability and has the capacity for out-of-office visits (but does not require them) (NASMHPD 2023).

Racial Disparities In Diagnosis

As discussed extensively in episode 143, racial bias in diagnostic practice is an important contributing factor. Research shows that in diagnosis of psychotic illness, African American/Black patients have a rate, on average, of three to four times higher than Euro-American/White patients, and Latinx American/Hispanic patients are disproportionately diagnosed with psychotic disorders on average about three times higher compared to Euro-American/White patients (Schwartz & Blankenship, 2014).

There are several potential reasons for this. In addition to racial bias leading to potential misdiagnosis, there is other data that suggests a true disparity in illness prevalence related to social determinants of health. These findings suggest that racial and ethnic disparities in the rates of obstetric complications in the United States could contribute to a developmental trajectory toward psychosis. Additionally, chronic stress due to discrimination against racial and ethnic minoritized individuals can be linked to development of psychosis (Anglin et al., 2021).

Socioculturally-Sensitive Care And Supervision

Socioculturally-attuned psychiatric care is important across the board and is particularly relevant in treatment of patients with psychotic illness, given the above racial disparities discussed. It is vital for psychiatrists to develop effective practices around actively addressing sociocultural context within the patient-doctor relationship. Location of self practices, largely pioneered in the family therapy field, provide a thoughtful approach to dialogue in addressing how the identities of the therapist and the corresponding privilege or subjugation associated with these identities in society can play out in the therapeutic relationship.

Effective use of these practices signals that the therapist is open to exploring how these issues influence patients’ lives (Watts-Jones 2010; Knudson-Martin 2019). Specifically, racial trauma is a topic that tends to be left out of conversations, even in standard care “trauma-informed'' practices (Hardy 2023). Supervision around culturally-sensitive care for trainees is needed in order to teach socioculturally-attuned practices. This starts with culturally-sensitive supervision, which includes practices around location of self, as discussed above. This normalizes and invites conversations around privileged and subjugated identities of supervisor and trainee and how these factors may affect supervision dynamic (Hardy & Bobes, 2016).

Neuromodulation And Psychedelics

For patients resistant to clozapine, augmenting with ECT has added benefit (Petrides et al., 2015).
3,4-Methylenedioxy methamphetamine (MDMA) has emerged as a novel therapeutic that has potential for use in negative symptoms of schizophrenia. This is an important area of research, given that there are no FDA-approved treatments for negative symptoms, which are a major cause of functional impairment in disability in the illness (Arnovitz et al., 2022).

Digital Psychiatry

Technology offers the potential to disrupt the way psychosis is managed and monitored. Researchers are interested in identifying markers of psychosis in order to detect relapse, which can allow for earlier treatment intervention and better monitoring of treatment response and medication adherence. Research has shown that the median duration of untreated psychosis in community treatment settings is more than 14 months (Addington et al., 2023). As access to digital technologies such as smartphones, wearables, and social media have become more pervasive, researchers have begun examining this digital data for signals of relapse. This concept of using in-situ active and passive data from a person’s smartphone to identify digital biomarkers of mental illness has been referred to as “digital phenotyping” (Torous et al., 2016).

At ZHH, researchers have begun to discover associations between social media and online activity and psychosis. One such research study examined online search activities in 105 patients with schizophrenia spectrum disorder compared to healthy volunteers and found differences in the frequency, timing and content of their search activity (Birnbaum et al., 2020). Furthermore, in later studies examining patient-generated social media activities from platforms such as Facebook and Instagram, researchers were able to identify distinct linguistic and behavioral patterns that were associated with schizophrenia spectrum disorders (Birnbaum et al., 2020; Hänsel et al., 2023). This research highlights the potential to utilize social media and online activity to create digital biomarkers for psychosis that could be used clinically to identify patients who have relapsed and potentially target interventions more quickly. In fact, the ZHH team is studying the potential of harnessing differences in search habits of people with psychosis in order to deliver advertisement-based interventions aimed at driving help-seeking behavior (Kirschenbaum et al., 2020; Birnbaum et al., 2017; Birnbaum et al., 2022).

In order to begin to implement this clinically, several institutions have begun creating “digital clinics” which integrate the use of mobile apps into psychiatric care through digital phenotyping as well as for digital interventions, such as journaling tools, mindfulness activities, medication reminders, and safety planning (King et al., 2023). This new clinical model of care has led to the emergence of a new clinical role, that of a “digital navigator” or a “digital health coach” (Wiśniewski et al., 2020). This is a team member with training in digital health whose role is to assist patients and providers in choosing apps and offering technical support.

However, with the adoption of such tools, it is important to consider the potential risks of such technologies. Data privacy is a main concern, as platforms that aggregate sensitive patient data are at risk of data leaks. A recent 2022 report by researchers at Mozilla found that nearly 60% of popular mental health apps had privacy practices that fell short of Mozilla’s minimum standards (Mozilla 2022). Another potential negative impact is the risk of bias within technologies, which could exacerbate existing health inequities. For example, studies have shown that there is a potential for racial bias in algorithms (SITNFlash 2020). Thus, it will be important for developers of such technologies to utilize ethnically and racially diverse data sets when developing algorithms and to check for potential biases.
