Before It's Too Late: Multistakeholder Perspectives on Compassionate Access to Investigational Drugs for Pediatric Patients With Cancer

A Qualitative Interview Study on Expanded Access Clinical Trials for Compassionate Use in Japan

Purpose

An expanded access clinical trials (EACTs) provides exceptional patient access to investigational new drugs for life-threatening diseases for which no effective treatment exists. Based on public information, we have studied EACTs since 2016, when the EACT system was launched in Japan. In this study, we investigated the reality of EACTs by interviewing pharmaceutical companies and clarifying how they view them.

Patients and Methods

We conducted semi-structured interviews with 10 pharmaceutical companies developing new drugs. This study aims to clarify the status of EACTs, so we selected pharmaceutical companies that develop innovative drugs for which they may perform EACTs (however, experience in conducting EACTs was optional).

Results

All those surveyed were aware of EACTs. Twelve access clinical trials were conducted, and the EACT implementation rate for pivotal clinical trials was 2.5%. The most common reason for implementing an EACT was "requests from physicians and medical institutions" (nine companies, 90.0%), and the most common reason for not implementing an EACT was "the applicability of the system" (five companies). Improvements to EACTs were identified by eight companies (80.0%); financial assistance by six companies (60.0%); reducing the scope of data to be collected and simplifying the procedure by six companies (60.0%). Seven companies (70.0%) responded that a Single Patient Investigational New Drug Application should be conducted, suggesting that the system should be revised.

Conclusion

An interview survey of ten pharmaceutical companies developing new drugs in Japan regarding expanded access clinical trials indicated that there were issues with the system. Many wished to improve the system by establishing a single patient access system, supporting resources, and simplifying procedures. Based on our interviews with 10 Japanese pharmaceutical companies, it was found that the system needed to be improved by introducing a single patient access system, providing supporting resources, and simplifying procedures. In Japan, about eight years have passed since EACT was established, and it appears a revision of the EACT legislation is due.

Benefit assessment of extended dosing in cancer patients after their withdrawal from clinical trials

Background: Clinical trials have been widely recognized as an effective treatment approach by physicians and cancer patients alike. Physicians' evaluations suggest that many patients are likely to continue experiencing benefits from extended dosing of investigational new drugs even after withdrawing from clinical trials. Objective: Given the uncertainty surrounding the efficacy and safety of investigational new drugs, it is essential to continually assess the benefits of extended dosing for patients. Methods: The trial group for this study comprised patients who requested extended dosing after withdrawing from clinical trials at Hunan Cancer Hospital between 2016 and 2020. The control group consisted of patients who received conventional treatment and were enrolled in a 1:1 ratio. Follow-up assessments were conducted every 3 months for both groups, and included monitoring of patients' health status, survival time, disease control or remission, treatment modalities received, and medical costs. Results: A total of twenty-three patient pairs were successfully matched for this study. The Ethics Committee approved extended dosing for all patients in the trial group, with an average gap period of 16.48 days between their withdrawal from clinical trials and continuous access to the investigational drugs. The median overall survival for patients after withdrawal from clinical trials was 17.3 months in the extended dosing group and 12.9 months in the control group, with no significant difference observed between the two groups (p > 0.250). The median total cost of treatment after the previous clinical trial was 38,006.76 RMB, of which the median cost of therapeutic drugs for conventional treatment was 15,720 RMB, while extended dosing was provided free of charge. Conclusion: Extended dosing can indeed provide benefits, including survival benefits and economic benefits, to cancer patients after their withdrawal from clinical trials and will clinically present an additional treatment option for patients.

Measuring Safety and Outcomes for the Use of Compassionate and Off-Label Therapies for Children, Adolescents, and Young Adults With Cancer in the SACHA-France Study

Importance

Innovative anticancer therapies for children, adolescents, and young adults are regularly prescribed outside their marketing authorization or through compassionate use programs. However, no clinical data of these prescriptions is systematically collected.

Objectives

To measure the feasibility of the collection of clinical safety and efficacy data of compassionate and off-label innovative anticancer therapies, with adequate pharmacovigilance declaration to inform further use and development of these medicines.

Design, Setting, and Participants

This cohort study included patients treated at French pediatric oncology centers from March 2020 to June 2022. Eligible patients were aged 25 years or younger with pediatric malignant neoplasms (solid tumors, brain tumors, or hematological malignant neoplasms) or related conditions who received compassionate use or off-label innovative anticancer therapies. Follow up was conducted through August 10, 2022.

Exposures

All patients treated in a French Society of Pediatric Oncology (SFCE) center.

Main Outcomes and Measures

Collection of adverse drug reactions and anticancer activity attributable to the treatment.

Results

A total of 366 patients were included, with a median age of 11.1 years (range, 0.2-24.6 years); 203 of 351 patients (58%) in the final analysis were male. Fifty-five different drugs were prescribed, half of patients (179 of 351 [51%]) were prescribed these drugs within a compassionate use program, mainly as single agents (74%) and based on a molecular alteration (65%). Main therapies were MEK/BRAF inhibitors followed by multi-targeted tyrosine kinase inhibitors. In 34% of patients at least a grade 2 clinical and/or grade 3 laboratory adverse drug reaction was reported, leading to delayed therapy and permanent discontinuation of the innovative therapy in 13% and 5% of patients, respectively. Objective responses were reported in 57 of 230 patients (25%) with solid tumors, brain tumors, and lymphomas. Early identification of exceptional responses supported the development of specific clinical trials for this population.

Conclusions and Relevance

This cohort study of the SACHA-France (Secured Access to Innovative Medicines for Children with Cancer) suggested the feasibility of prospective multicenter clinical safety and activity data collection for compassionate and off-label new anticancer medicines. This study allowed adequate pharmacovigilance reporting and early identification of exceptional responses allowing further pediatric drug development within clinical trials; based on this experience, this study will be enlarged to the international level.

Early access provision: Awareness, educational needs and opportunities to improve oncology patients' access to care

BACKGROUND

An unmet medical need exists for many oncology patients who cannot be treated satisfactorily by available therapeutic options. Early access provision (EAP) is endorsed by competent authorities to improve patient access to innovative medicinal products (InMPs). This paper determined awareness and understanding among practicing physicians of integrated EAP protocols, and of the procedures involved in EAP applications for oncology trials prior to marketing authorization.

METHODS

An on-line, fully anonymous survey reaching out to more than 3,258 physicians (including practicing oncologists) was initiated between November 2020 - January 2021. Participants were questioned about their knowledge and understanding of EAP and the decision processes involved, level of experience, interest for further educational activities and opportunities to improve the process, both in general and specifically during the COVID-19 pandemic. The frequency of EAP protocols for oncology InMPs was identified by a search of ClinicalTrials.gov and EU Clinical Trials registers.

RESULTS

Survey results (75% oncologists) indicated 75% of respondents were 'very comfortable' or 'comfortable' with using EAP for their patients, but only 54.5% correctly answered the specific knowledge-based question related to the EAP definition. For 56% of respondents, experience with EAP in daily practice was very limited. Two-thirds indicated an average or lower level of understanding about the application process and regulatory requirements involved (65.2% and 66.0%, respectively). Knowledge on data collection and serious adverse event reporting under EAP was lower at 57.8% and 50.5% of respondents, respectively. Awareness of physician responsibilities was high in 59.7% of respondents, but fewer understood roles and responsibilities of manufacturing companies (31.2%). Most indicated they would consider clinical efficacy and safety data from comparative phase III randomized controlled trials as of high importance to support their decision to apply for EAP (93.4% and 86.8%, respectively). During the COVID-19 pandemic, the majority of respondents highlighted the need to improve and adapt EAP with regard to the application process and documentation (83.8%), InMP supply and logistics (88.4), and safety reporting process (78.0%). Of identified oncology trials with a ClinicalTrials.gov protocol, only 149 (0.4%) included EAP, and 23 used the data to receive a marketing authorization during the period Jan 2015 to December 2020. Of oncology trials with a EudraCT protocol, only 21 (0.23%) included EAP, of which 6 were used to receive a conditional or full marketing authorisation over the same period.

CONCLUSION

Use of EAP in daily practice remains limited. Challenges posed by the EAP process, together with a lack of education on this topic, might contribute to its under-utilization and influence access of oncology patients to care. Continuous educational efforts from different stakeholders are required to better inform and support practicing oncologists during the EAP application process and regulatory framework follow up. Education should also be provided on EAP roles and responsibilities, monitoring, and potential adaptations when faced with specific challenges, such as the current COVID-19 pandemic.

The scope of childhood cancer in South Africa: A response to 'Childhood cancers in a section of the South African private health sector - Analysis of medicines claims data'

Childhood cancer is an under resourced medical field that is emerging as a great healthcare concern in low- and middle-income countries such as South Africa. Therefore, reporting data in this field that may inform policymakers should be representative of the subject matter. This article aims to discuss why medicines claims as an indicator for incidence, as per an article published in 2020, is not representative of childhood malignancies in the South African setting. Literature to support the commentary were sourced using Pubmed, Google scholar, and data presented by members of the South African Children’s Cancer Study Group (SACCSG). Private medical aid coverage in South Africa between 2002 and 2018 varied between 15.5% and 18.2%. Of these, 9.5% were children under 18 years and 3.5% were under the age of six. Only 13.5% of children were treated in private paediatric oncology units during 2015. The limitations in the study were the variable medical aid coverage, the disproportionate age representation, and lack of reliable indicators for measurement and calculation of incidence. Utilising one medicines claims data base to evaluate the incidence of childhood cancer in South Africa is not representative and cannot inform policy.
