Afamitresgene autoleucel for advanced synovial sarcoma and myxoid round cell liposarcoma (SPEARHEAD-1): an international, open-label, phase 2 trial

BACKGROUND

Afamitresgene autoleucel (afami-cel) showed acceptable safety and promising efficacy in a phase 1 trial (NCT03132922). The aim of this study was to further evaluate the efficacy of afami-cel for the treatment of patients with HLA-A*02 and MAGE-A4-expressing advanced synovial sarcoma or myxoid round cell liposarcoma.

METHODS

SPEARHEAD-1 was an open-label, non-randomised, phase 2 trial done across 23 sites in Canada, the USA, and Europe. The trial included three cohorts, of which the main investigational cohort (cohort 1) is reported here. Cohort 1 included patients with HLA-A*02, aged 16-75 years, with metastatic or unresectable synovial sarcoma or myxoid round cell liposarcoma (confirmed by cytogenetics) expressing MAGE-A4, and who had received at least one previous line of anthracycline-containing or ifosfamide-containing chemotherapy. Patients received a single intravenous dose of afami-cel (transduced dose range 1·0 × 109-10·0 × 109 T cells) after lymphodepletion. The primary endpoint was overall response rate in cohort 1, assessed by a masked independent review committee using Response Evaluation Criteria in Solid Tumours (version 1.1) in the modified intention-to-treat population (all patients who received afami-cel). Adverse events, including those of special interest (cytokine release syndrome, prolonged cytopenia, and neurotoxicity), were monitored and are reported for the modified intention-to-treat population. This trial is registered at ClinicalTrials.gov, NCT04044768; recruitment is closed and follow-up is ongoing for cohorts 1 and 2, and recruitment is open for cohort 3.

FINDINGS

Between Dec 17, 2019, and July 27, 2021, 52 patients with cytogenetically confirmed synovial sarcoma (n=44) and myxoid round cell liposarcoma (n=8) were enrolled and received afami-cel in cohort 1. Patients were heavily pre-treated (median three [IQR two to four] previous lines of systemic therapy). Median follow-up time was 32·6 months (IQR 29·4-36·1). Overall response rate was 37% (19 of 52; 95% CI 24-51) overall, 39% (17 of 44; 24-55) for patients with synovial sarcoma, and 25% (two of eight; 3-65) for patients with myxoid round cell liposarcoma. Cytokine release syndrome occurred in 37 (71%) of 52 of patients (one grade 3 event). Cytopenias were the most common grade 3 or worse adverse events (lymphopenia in 50 [96%], neutropenia 44 [85%], leukopenia 42 [81%] of 52 patients). No treatment-related deaths occurred.

INTERPRETATION

Afami-cel treatment resulted in durable responses in heavily pre-treated patients with HLA-A*02 and MAGE-A4-expressing synovial sarcoma. This study shows that T-cell receptor therapy can be used to effectively target solid tumours and provides rationale to expand this approach to other solid malignancies.

What reproductive follow-up for adolescent and young women after cancer? A review

Fertility capacity has been shown to be one of the main concerns of young cancer survivors. Gonadotoxic treatments may lead to both premature ovarian failure and/or infertility. This review aimed to define which, and when, reproductive indicators should be followed-up to help doctors to counsel patients regarding their fertility and ovarian function, and to determine if a second stage of fertility preservation after the end of cancer treatment is clinically relevant. Longitudinal assessment of anti-Müllerian hormone (AMH) concentrations during cancer treatment indicates the degree of follicular depletion, and allows discrimination between low and high gonadotoxic treatments. Sustained low AMH concentrations after treatment, especially in the case of alkylating protocols, may reduce the duration of the conception window significantly, and expose the patient to the risk of premature ovarian failure. It remains unknown whether this may impact further fertility capacity because of the lack of systematic follow-up of adolescent and young adult (AYA) women after chemo-radiotherapy. It appears that dedicated reproductive follow-up of AYA women under cancer treatment is needed to refine fertility preservation strategies, and to determine if low AMH concentrations after treatment impact the chance of pregnancy in this specific survivor population.

French National Diagnostic and Care Protocol for antiphospholipid syndrome in adults and children

Antiphospholipid syndrome (APS) is a chronic autoimmune disease involving vascular thrombosis and/or obstetric morbidity and persistent antibodies to phospholipids or certain phospholipid-associated proteins. It is a rare condition in adults and even rarer in children. The diagnosis of APS can be facilitated by the use of classification criteria based on a combination of clinical and biological features. APS may be rapidly progressive with multiple, often synchronous thromboses, resulting in life-threatening multiple organ failure. This form is known as "catastrophic antiphospholipid syndrome" (CAPS). It may be primary or associated with systemic lupus erythematosus (associated APS) and in very rare cases with other systemic autoimmune diseases. General practitioners and paediatricians may encounter APS in patients with one or more vascular thromboses. Because APS is so rare and difficult to diagnosis (risk of overdiagnosis) any suspected case should be confirmed rapidly and sometimes urgently by an APS specialist. First-line treatment of thrombotic events in APS includes heparin followed by long-term anticoagulation with a VKA, usually warfarin. Except in the specific case of stroke, anticoagulants should be started as early as possible. Any temporary discontinuation of anticoagulants is associated with a high risk of thrombosis in APS. A reference/competence centre specialised in autoimmune diseases must be urgently consulted for the therapeutic management of CAPS.

Autologous T cell therapy for MAGE-A4+ solid cancers in HLA-A*02+ patients: a phase 1 trial

Affinity-optimized T cell receptors can enhance the potency of adoptive T cell therapy. Afamitresgene autoleucel (afami-cel) is a human leukocyte antigen-restricted autologous T cell therapy targeting melanoma-associated antigen A4 (MAGE-A4), a cancer/testis antigen expressed at varying levels in multiple solid tumors. We conducted a multicenter, dose-escalation, phase 1 trial in patients with relapsed/refractory metastatic solid tumors expressing MAGE-A4, including synovial sarcoma (SS), ovarian cancer and head and neck cancer ( NCT03132922 ). The primary endpoint was safety, and the secondary efficacy endpoints included overall response rate (ORR) and duration of response. All patients (N = 38, nine tumor types) experienced Grade ≥3 hematologic toxicities; 55% of patients (90% Grade ≤2) experienced cytokine release syndrome. ORR (all partial response) was 24% (9/38), 7/16 (44%) for SS and 2/22 (9%) for all other cancers. Median duration of response was 25.6 weeks (95% confidence interval (CI): 12.286, not reached) and 28.1 weeks (95% CI: 12.286, not reached) overall and for SS, respectively. Exploratory analyses showed that afami-cel infiltrates tumors, has an interferon-γ-driven mechanism of action and triggers adaptive immune responses. In addition, afami-cel has an acceptable benefit-risk profile, with early and durable responses, especially in patients with metastatic SS. Although the small trial size limits conclusions that can be drawn, the results warrant further testing in larger studies.

Abstract A038: Enrollment of pediatric and adolescent patients with MAGE-A4+ advanced synovial sarcoma into cohort 2 of SPEARHEAD-1: a phase 2 trial of afamitresgene autoleucel (“afami-cel” [formerly ADP-A2M4])

Background: Afami-cel is an autologous, specific peptide enhanced affinity receptor T-cell therapy genetically engineered to target MAGE-A4+ solid tumors in HLA-A*02+ patients. SPEARHEAD-1 (NCT04044768) is a Phase 2, two-cohort, single-arm, open-label trial evaluating afami-cel in patients with advanced/metastatic synovial sarcoma or myxoid/round cell liposarcoma (MRCLS) and is the largest trial in metastatic synovial sarcoma to date. Preliminary data from Cohort 1 in 47 heavily pre-treated patients aged 16–75 years from 22 centers in North America and Europe, showed an overall response rate (ORR) per independent review of 34.0% (14/39 [35.9%] in synovial sarcoma; 2/8 [25%] in MRCLS) and a favorable benefit–risk profile with mainly low-grade cytokine release syndrome and tolerable/reversible hematologic toxicities.1 The reported ORR in synovial sarcoma in Cohort 1 was higher than reported ORRs for current standard-of-care therapies, such as pazopanib and trabectedin, in the second-line metastatic setting.2 As synovial sarcoma is the most common malignant nonrhabdomyosarcoma soft-tissue sarcoma in children and adolescents with few treatment options, especially for recurrent disease, the trial opened a second cohort to allow enrollment of pediatric patients with MAGE-A4+ synovial sarcoma who experienced disease progression post first-line chemotherapy, and to better understand MAGE-A4 tumor expression in children. Methods: Cohort 2 of the SPEARHEAD-1 trial is enrolling patients with advanced synovial sarcoma who are at least 10 years old and weigh at least 40 kg. The planned enrollment is 45 patients, including up to 13 children, to enable a pooled analysis of ORR in >90 patients across Cohorts 1 and 2. HLA and MAGE-A4+ screening in Cohort 2 is conducted at a central laboratory using the same method as Cohort 1; MAGE-A4 testing is done using a clinical trial assay. All patients enrolled in Cohort 2 undergo apheresis and their isolated T-cells are then transduced with the MAGE-A4c1032 TCR using a lentivirus vector, followed by ex vivo expansion. Prior to afami-cel infusion of 1–10 × 109 transduced T-cells, patients will receive lymphodepleting chemotherapy consisting of fludarabine (30 mg/m2/day for 4 days) and cyclophosphamide (600 mg/m2/day for 3 days). Disease will be assessed by independent review per RECIST v1.1 using computerized tomography or magnetic resonance imaging at weeks 4, 8, 12, 16, 24, and every 2 months thereafter until confirmed disease progression. Patients enter long-term follow-up for 15 years. 1. Van Tine BA, et al. Paper 30: CTOS 2021; Virtual 2. Carroll C, et al. Cancer Res 2021;81(13_Suppl): Abstract nr 2630.

Abstract LB001: Identifying MAGE-A4-positive tumors for SPEAR T-cell therapies in HLA-A*02-eligible patients

Autologous T-cells engineered with T-cell receptors (TCRs) targeting tumor antigens are promising therapies for metastatic solid cancers.1 Specific peptide enhanced affinity receptor (SPEAR) T-cell therapies are T-cells with engineered HLA-restricted TCRs that precisely target tumor cells with specific antigens, such as MAGE-A4 (a cancer testis antigen), presented on the surface by HLA molecules. In SPEAR T-cell clinical trials targeting MAGE-A4, a 2-step prescreen is done before enrolment. 1) Patients undergo HLA typing via a high-resolution (allelic, 4-digit) sequence-based assay, and those who are positive for the inclusion alleles (HLA-A*02:01P, 02:02P, 02:03P, 02:06P) and not positive for the exclusion allele A*02:05P are eligible. 2) Tumor MAGE-A4 testing is done via an immunohistochemical clinical trial assay (MAGE-A4+ cutoff: ≥30% tumor cell staining at ≥2+ intensity) in HLA-eligible patients. A screening protocol (NCT02636855) has been used in Phase 1 trials of first- and next-generation SPEAR T-cells targeting MAGE-A4 (NCT03132922, NCT04044859) with responses in multiple MAGE-A4+ tumors. As of November 19, 2021, 6,168 patients with 9 solid tumor types were screened at 32 sites across North America and Europe in this screening protocol; among which, 2,744 were HLA-eligible (eligibility rate: 45%, range per tumor type: 42%-55%). HLA-A*02:01 was the most frequent HLA-A*02 allele. Of these HLA-eligible patients, 1,549 had tumor tissues evaluable for MAGE-A4 expression; among which, 313 were MAGE-A4+ (MAGE-A4+ rate: 20%, range: 8%-54%) (Table). MAGE-A4 showed highest prevalence in synovial sarcoma and myxoid/round cell liposarcoma but was seen across all tumor types investigated. Our results will be discussed in the context of tumor histopathology, disease status, and demography. HLA and MAGE-A4 biomarker data will inform the therapeutic opportunities for SPEAR T-cells targeting MAGE-A4 in metastatic solid cancers. 1. D’Angelo et al. Cancer Discov. 2018;8:944.

POS1405 LESS THAN 50% FEMALES WITH CHRONIC RHEUMATIC INFLAMMATORY DISEASES CONTINUE A DMARD DURING PREGNANCY: A DESCRIPTIVE ANALYSIS OF THE NATIONAL FRENCH SOCIAL SECURITY DATABASE

Background

Treatment of patients with chronic rheumatic inflammatory diseases (CRID) during pregnancy has changed in the last decade, namely due to the availability of new DMARDs labelled to be used during pregnancy.

Objectives

To describe the anti-rheumatic drug use during pregnancy in women with CRID (i.e. rheumatoid arthritis (RA) or spondyloarthritis (SpA)) in France over the past decade.

Methods

This is a retrospective cohort study within the French Healthcare database (SNDS), which covers 98% of the French population. Adult women were included if they had RA or SpA according to CIM-10 codes, had started a singleton pregnancy between 2008 and 2017 (index date), and were continuously covered by this health insurance from 1-year before pregnancy onset to 1-year after end of the pregnancy or death (whichever comes first). The treatment exposures of interest were: NSAIDs, oral corticosteroids, csDMARD (methotrexate, leflunomide, sulfasalazine, azathioprine, hydroxychloroquine), biologics (anti-TNF, rituximab, abatacept, tocilizumab, ustekinumab, anakinra). Exposure during pregnancy was defined as at least one drug reimbursement from the 6 months before the last menstrual period (LMP) to the end of pregnancy period.

Results

Among the 35,737 adult women with a CIRD (40.7% with RA and 59.3% with SpA) who had a past history of DMARD reimbursement, 11,274 (41.7%) started a singleton pregnancy during the study period. In total, during preconception and pregnancy, 4,773 (42.3%) women were not delivered any DMARD nor corticosteroids, 769 (6.8%) were delivered corticosteroids alone, 3,639 (32.2%) a csDMARD alone and 2,862 (25.4%) a biologic (among whom 33.1% associated a csDMARD). Biologics delivered during pregnancy were mainly anti-TNFs (92.1%).

Exposure to NSAIDs was more frequent during the first trimester (30% patients) of pregnancy but occurred all along the pregnancy (6% and 2% in the second and third trimesters, respectively). Conversely, exposure to oral corticosteroids was stable during the pregnancy (33% to 27%); however, more than half of the prescriptions corresponded to doses higher than 10mg. Exposure to DMARDs including bDMARDs during pregnancy was more frequent during the first trimester, compared to the rest of the pregnancy (see graph).

Conclusion

Overall, less than 50% of women with a CRID who received a DMARD prior to the pregnancy continued to retrieve such treatment during pregnancy, and overall less than 20% were delivered biologics during pregnancy. Whether the withdrawal of DMARDs led to unfavorable maternal and pregnancy outcomes needs to be evaluated.

AB1391 19% PATIENTS WITH CHRONIC RHEUMATIC INFLAMMATORY DISEASES PRESENT AN UNFAVORABLE PREGNANCY OUTCOME: A DESCRIPTIVE ANALYSIS OF THE NATIONAL FRENCH SOCIAL SECURITY DATABASE

Background

patients with chronic rheumatic inflammatory diseases (CRID, i.e. rheumatoid arthritis (RA) or spondyloarthritis (SpA)) have been reported to have poorer pregnancy outcomes than the general population.

Objectives

to describe the pregnancy outcomes of singleton in patients with CRID in France in the past decade.

Methods

this is an analysis of the French Health Insurance claims database (SNDS), which represents 87% of the French population) from 2008 to 2016. To be included in the analysis patients had to be identified as RA or SpA according to existing diagnostic algorithms, to have at least one pregnancy declaration in the database, and to have continuous health insurance from 1-year before pregnancy onset to 1-year after end of the pregnancy or until death (if death occured before the 1-year-period after the end of pregnancy) to be included. Only the first singleton pregnancy occurring during the study period was included in this analysis. Both maternal and pregnancy outcomes were considered. Outcomes were identified either by ICM-10 codes or hospital discharge summaries discharge between 2008-2016.

Results

Among the 35 737 identified adult females with a CRID diagnosis (40.7% with RA and 59.3% with SpA), 27 722 (78%) had a pregnancy during the study period. 11 274 (42%) had received at least one DMARD prior to the pregnancy and were included in the analysis. Among them, only 4025 (36%) were exposed to DMARDs during pregnancy.

Mean (SD) age of females at the start of the pregnancy was 32 (5) years, and mean (SD) disease duration was 4 (4) years. Pregnancy ended before 13 WG in 21% and after 37 WG in 70% cases. Live-birth represented the most frequent pregnancy outcome (76.9%), and overall 34.7% patients presented at least one unfavorable outcome (see Table 1).

Conclusion

More than 75% pregnancies in patients with CRID resulted in a live-birth. Prevalence of miscarriage was surprisingly low, probably related to under-coding. Maternal and infant outcomes seemed comparable to general population. Whether medications had an impact on such outcomes is currently under evaluation.

[Methotrexate: How long between administration and conception?]

In women of childbearing age, methotrexate is prescribed in many indications other than cancer, either chronically (psoriasis, rheumatoid arthritis, IBD, etc.) or occasionally (ectopic pregnancies). The time given to these patients to consider pregnancy is currently subject to great variability depending on the sources. Analysis of the available objective evidence suggests that it is not justified to unnecessarily lengthen this period, and that conceiving the menstrual cycle following stopping methotrexate is quite possible.

Phase I dose escalation and expansion trial to assess the safety and efficacy of ADP-A2M4 SPEAR T cells in advanced solid tumors

102

Background: MAGE-A4 is a cancer/testis antigen with expression in many solid tumors promoting cell growth by preventing cell cycle arrest and apoptosis. This study (NCT03132922) evaluated safety and efficacy of SPEAR T-cells directed against the MAGE-A4 peptide expressed in 9 tumor types. Methods: This Phase I dose-escalation, expansion trial evaluated patients (pt) who were HLA-A*02 positive with advanced cancers that expressed the MAGE-A4 protein. Autologous T-cells from eligible patients were isolated, transduced with a lentiviral vector containing the MAGE-A4c1032 TCR, and expanded. Prior to ADP-A2M4 infusion, pts received a lymphodepletion regimen of cyclophosphamide and fludarabine. Cohorts 1, 2, 3, and expansion were to receive transduced cell doses of up to: 0.12 × 109, 1.2 × 109, 6 × 109, and 10 x 109, respectively. Results: As of 23 October 2019, 9 pts were treated in dose escalation with no DLTs; 25 pts were treated in expansion. Median age was 56.5 yr (range: 31-78). All pts received prior chemotherapy. Most common ( > 30%) AEs ≥Grade 3 were lymphopenia, leukopenia, neutropenia, anemia, thrombocytopenia, and febrile neutropenia. Two pts had trial-related deaths (aplastic anemia and CVA) leading to modification of the lymphodepletion regimen and eligibility criteria. In Cohort 3/expansion (28 pts), Best Overall Response was PR (7), SD (11), PD (5), non-evaluable (5). All PRs, at the time of data cut-off, were in patients with synovial sarcoma. Transduced T-cells were detectable in all patients. Tumor infiltration of SPEAR T-cells was detectable in several cohort 3/expansion pts. Conclusions: The Phase I single agent ADP-A2M4 trial will complete enrollment shortly and updated data will be presented. ADP-A2M4 shows promising efficacy and a manageable safety profile at a dose range of 1.2 – 10 × 109. Clinical activity in various tumors has led to a separate on-going low dose radiation sub-study of this trial, a Phase II trial in sarcoma (SPEARHEAD-1, NCT04044768), and a Phase I trial (SURPASS, NCT04044859) with ADP-A2M4CD8, a next-generation SPEAR T-cell targeting MAGE-A4. Clinical trial information: NCT03132922.

Pregnancy and newborn outcomes after exposure to bisphosphonates: a case-control study

We analyzed women and newborn outcome after maternal exposure to BPs. BPs have no teratogenic effect on the 36 analyzed pregnancies compared to unexposed controls matched on women underlying diseases (either systemic disease, either "bone" disease) but some outcome differed: neonatal complications rate in systemic diseases and live birth rate in bone diseases).

INTRODUCTION

The effect of bisphosphonates (BPs) during pregnancy remains unclear. We aimed to study pregnancy outcomes in women exposed to BPs during pregnancy.

METHODS

Data for cases and controls were from the French Reference Centre of Teratogenic Agents. Cases were women who received BPs in the 6 weeks before or during a pregnancy and had systemic or bone diseases. We included two respectively matched control groups: women with systemic diseases not exposed to BPs and healthy women not exposed to BPs or any teratogenic agent. Four controls were assigned to each case.

RESULTS

Thirty-six women were exposed to BPs including 5 just before pregnancy and 30 during the first trimester; 23 had systemic diseases (systemic lupus erythematosus, n = 5; rheumatoid arthritis, n = 5; other, n = 13) and 13 had bone diseases. Rate of observed congenital malformations did not differ in women with a systemic or a bone disease compared to their respective controls (respectively 2/23 [8.7%] vs 2/92 [2.2%], p = 0.178 and 0/13 [0%] vs 0/52 [0%], p = 1.00). Among women with systemic diseases, non-specific neonatal complications were more frequent for cases (4/16 [25.0%] vs 4/64 [6.3%], p = 0.027). Among women with bone disorders, the live birth rate was lower for cases than healthy controls (8/10 [80%] vs 50/50 [100%], p = 0.025).

CONCLUSION

We found no major teratogenic effects of BPs, but rates of neonatal complications were increased for women with systemic diseases, as were spontaneous abortions for women with bone diseases likely linked to the severity of the underlying diseases and concomitant medications.

Meta-Analysis of Caregiver-Directed Psychosocial Interventions for Schizophrenia

With the recent movement toward a personal-recovery paradigm to treat schizophrenia, the locus of mental health care delivery has shifted toward community-based care. Family caregivers comprise a substantial component of that community, and are often providing care for longer periods, but often have no formal training or support. Caregiver-directed psychosocial interventions (CDPI) have been developed to train and assist caregivers in their efforts to maximize the odds of treatment success for those in their care. This meta-analysis compared CDPI versus treatment as usual (TAU) on outcomes such as hospitalization, relapse, non-compliance, and "other outcomes" (emergency services utilization, suicide attempt, and death). A systematic literature search (2005-2015) was conducted to identify randomized controlled trials of outpatient administered CDPI versus TAU to treat adult patients recovering from schizophrenia. Relative risks (RR) with 95% confidence intervals derived via random effects meta-analysis were calculated to compare CDPI versus TAU on the aforementioned outcomes. Eighteen of the 693 citations were retained for analysis. Overall RR for CDPI versus TAU suggested improved outcomes associated with CDPI: hospitalization [0.62 (0.46, 0.84) p < 0.00001], relapse [0.58 (0.47, 0.73) p < 0.00001] and other outcomes [0.70 (0.19, 2.57) p = 0.59]. CDPI was associated with significantly better compliance with medication and clinical activities combined [0.38 (0.19, 0.74) p = 0.005]. Medication compliance alone favored CDPI but was non-significant. Compliance with clinical activities alone favored CDPI significantly [0.22 (0.11, 0.47) p < 0.00001]. CDPI is associated with reductions in hospitalization, relapse, and treatment non-compliance.

An assessment of injection site reaction and injection site pain of 1-month and 3-month long-acting injectable formulations of paliperidone palmitate

PURPOSE

To evaluate injection site reactions and pain following paliperidone palmitate 1-month (PP1M) and 3-month (PP3M) administration using safety data of double-blind (DB), noninferiority study.

METHODS

Patients (n = 1,429) with schizophrenia, treated with PP1M (50-150 mg-eq, 17-week open-label [OL] phase) were randomized to PP1M or PP3M in 48-week DB phase.

FINDINGS

PP1M and PP3M injections were well tolerated. Incidence of induration, redness, and swelling were low in both phases (OL: 9-12%; DB: 7-13%), and were mostly mild in both groups. Mean (SD) visual analog scale scores decreased from OL-baseline (22.0 [21.6]) to DB-baseline (19.5 [20.6] vs. 18.4 [20.4]) and DB-endpoint (15.6 [17.9] vs. 15.5 [18.3]).

PRACTICE IMPLICATIONS

Injection site reactions and pain were low and similar between both treatments, regardless of administration site and dose.

Maternal consumption of quinine-containing sodas may induce G6PD crises in breastfed children

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzyme defect often presenting with neonatal jaundice and/or hemolytic anemia. G6PD hemolytic events are linked with exposure to a pro-oxidant agent. We here report three cases of initial G6PD crises in breastfed children secondary to maternal consumption of a tonic drink which contains quinine. Quinine was found in breast milk of one of the mothers after she consumed tonic water.

CONCLUSION

The amount of quinine that is transmitted through breast milk appears to be sufficient to induce G6PD crises in breastfed children. We hence recommend that consumption of quinine-containing sodas during breastfeeding should be avoided in populations with a high prevalence of G6PD deficiency. What is Known: • G6PD hemolytic events are linked with exposure to a pro-oxidant agent. • Ingestion of fava beans by a mother who was breastfeeding has been reported to induce a neonatal G6PD crisis. What is New: • Maternal consumption of tonic drink which contains quinine appears to be sufficient to induce G6PD crises in breastfed children. • Maternal consumption of quinine-containing sodas during breastfeeding should be avoided in populations with a high prevalence of G6PD deficiency.

[Isotretinoin: compliance with recommendations in childbearing women]

INTRODUCTION

The aim of this survey is to ascertain if the incidence of isotretinoin exposed pregnancies was reduced by the late recommendations of prescription and issue (AMM modification on 06/08/2001 and 25/09/2001).

METHODS

All isotretinoin exposed pregnancies registered by the French Regional Drug Monitoring Centres, the Information Centre for Teratogenic Agents and Roche (Roaccutane), Pierre Fabre (Curacné Gé) and Expanscience (Procuta Gé) laboratories, from January 1st, 1999 to December 31st, 2002, were analysed. Enforcement of the strengthening of isotretinoin prescription recommendations was analysed on a sample of 68 prescriptions from 45 pharmacies throughout France.

RESULTS

In 4 years, 103 isotretinoin exposed pregnancies (Roaccutane 97 p. 100, Curacné(R) Gé 3 p. 100) during teratogenic risk period, were registered. Pregnancy started less than one month after isotretinoin stopping (37 p. 100), during the treatment (43 p. 100), or was in progress when the treatment was initiated (20 p. 100). The reason of the 22 lacking contraception was known 12 times, i.e. an absence of prescription (6 times), a refusal to take a prescribed contraception (3 times) and a self-medication (3 times). Among the 71 pregnancies whose contraceptive status is known, 48 p. 100 could had been avoided if recommendations had been followed (pregnancies due to a premature stopping or an absence of contraception). The issue of pregnancies is a voluntary termination in 60 cases (87 p. 100). Malformations frequency is 25 p. 100. Incidence of isotretinoin exposed pregnancies remained stable, 0.26/1000 treated women (vs 0.34 after 2001's AMM modifications). Of 68 prescriptions studied, 23 (24 p. 100) carried all the legal warnings, which is close to the previous survey's results. Contraception was in accordance with the recommendations in 78 p. 100 of cases and women learned and applied information given in 38 p. 100 of cases. At last, only 6 patients (9 p. 100) have both a correctly written prescription, a contraception and a time between the pregnancy test date and prescription and issue dates, in accordance with the licence and have had a correct information and understood it. Regarding the previous survey, pregnancy test before treatment was more often prescribed (96 p. 100 vs 88 p. 100). On the other hand, less women knew the necessity to keep on taking contraception one month after isotretinoin stopping (82 p. 100 vs 93 p. 100).

CONCLUSION

Despite 3 successive isotretinoin prescription and issue recommendations strengthening in childbearing women, pregnancies can't be totally avoided. Bad compliance concerns the prescription and/or an incomplete or not understood information by the patient who does not scrupulously apply the care and contraception agreement. However, this study does not allow to assess the proportion of issued prescriptions despite their non-accordance with the licence criteria. The National Commission of Pharmacovigilance did not like to limit isotretinoin prescription to dermatologists only. It estimates that the administrative authority must intensify information by dermatologists, general practitioners and pharmacists, about measures to take to avoid an exposure to isotretinoin during pregnancy.

Un rôle difficile pour le pharmacien d’officine, le conseil en matière de médicament et grossesse

Tragedies subsequent to use of medication at the beginning of pregnancy have given rise to extreme distrust, placing the retail pharmacist in an uncomfortable situation. A survey of pharmacists in France has revealed that pregnant women ask for more information than any other patients, particularly when it comes to continuing medication started before pregnancy. In such cases, 57% of the polled pharmacists recommended discontinuation of the medication. Ninety percent thought they were sufficiently informed and massively recommended a prudent attitude. Their wish was to have an independent high-performance information tool available. There is such a tool: the Teratogenic Agent Information Center, rarely used by pharmacists. With the support of such a structure, 80% would be eager to take on more responsibilities in counseling patients and preventing teratogenic risks, in relation with other healthcare workers, thus guaranteeing high-quality medication counseling.

[Cancer and pregnancy: risks of exposure to cancer chemotherapy during pregnancy]

Animal studies reveal that almost all antineoplastic agents are teratogenic. But extrapolation to human beings is not simple because of species differences. Few human data are available, most are sporadic case reports. Other toxic effects for the fetus and neonate (intrauterine exposure during second and third trimester) must be taken in consideration when prescribing chemotherapy for pregnant women. Adverse effects observed in adult and children are helpful if data during fetal life are lacking. Long-term studies are needed to evaluate the transplacental effects of chemotherapy during pregnancy; these studies should assess the child's mental and physical development, infertility and the occurrence of second malignancies.

[Pregnancy outcome in inflammatory bowel diseases]

OBJECTIVE

To assess pregnancy outcome in relation to disease activity and maintenance therapy in patients with inflammatory bowel disease.

METHODS

A postal questionnaire was sent to every woman of child-bearing age followed for inflammatory bowel disease in three referral centers (Rothschild, Saint-Lazare, Saint-Louis). Response rate was 65%.

RESULTS

One hundred and forty-four pregnancies (153 fetuses) in 138 women (122 had Crohn's disease) were reported. Outcome of pregnancy was normal (baby > 2500 g, without malformation) in 115 cases (77%). There were 17 cases of preterm birth (11.5%), 3 cases of hypotrophy, and 14 pregnancy losses (9 miscarriages (6%), 4 therapeutic abortions for major malformation (2.8%)). Percentages of normal pregnancy outcome were not different between patients who continued maintenance therapy and those who stopped: respective percentages were 75 vs 73% in patients receiving mesalamine or olsalazine (n = 30), and 60 vs 75% in patients receiving azathioprine (n = 22).

CONCLUSION

In a selected series of women with inflammatory bowel disease, pregnancy outcome is approaching that observed in a normal population, except for an elevated rate of preterm births. There is no need to stop maintenance therapy with 5-aminosalicylates or azathioprine during pregnancy.

Foetal outcome in women with inflammatory bowel disease treated during pregnancy with oral mesalazine microgranules

BACKGROUND

Little information is available about the safety of high doses of mesalazine during pregnancy.

AIM

To study the fate of pregnancy and foetal outcome in women taking 1-4 g/day of mesalazine microgranules for inflammatory bowel disease.

PATIENTS AND METHODS

Case reports were collected from the Pharmacovigilance Department of Ferring SA, France, from a survey conducted in three gastroenterology units, and from a teratology information service. The evolution of pregnancy and foetal outcome were assessed by questionnaire.

RESULTS

The study covered a total of 123 pregnancies (126 foetuses). Ninety-six women took mesalazine during the first trimester, 85 during the second and 83 during the third. The mean daily dose was 2.1+/-0.8 g; 86 women received <3 g/day (low-dose group), 37 women received > or =3 g/day (high-dose group). The following abnormalities were observed in the low-dose and high-dose groups, respectively: ectopic pregnancy (1/0), spontaneous abortions (1/1), foetal death (0/1), premature deliveries (3/5, P < 0.05), congenital malformations (3/1) and one case of lethal oxalosis. Abnormalities were not considered to be related to mesalazine.

CONCLUSIONS

The use of oral mesalazine microgranules during pregnancy is safe at doses < or =2 g/day, and probably also at a dose of 3 g/day.

INTERVENTIONS

Case by case, individual estimations of the risks have been provided.

MAIN OUTCOME MEASURE

Each pregnancy issue has been analyzed.

RESULTS

No teratogenic or fetal toxic effect has been noted.

CONCLUSION

No specific hazard has been observed among newborns after inadvertent exposures to a GnRH-a during the first 20 weeks of pregnancy.

Cholesterol prevents the teratogenic action of AY 9944: importance of the timing of cholesterol supplementation to rats

These studies were conducted to determine whether dietary cholesterol supplementation could prevent fetal malformations induced by the amphipathic drug AY 9944, which is well known as a cholesterol biosynthesis inhibitor, and to investigate whether the plasma maternal sterol level and the nature of the sterols found in treated Wistar rats could explain this prevention. Pituitary agenesis was the most constant element of holoprosencephaly when AY 9944 was administered on d 4 of gestation at two dosages, 50 or 75 mg/kg. The rate of malformed fetuses was dose related. A strong negative correlation was established between maternal plasma sterol levels on d 10 of gestation (day of pituitary gland formation) and the rate of fetal anomalies (r = -0.97, P less than 0.01). Supplementation of AY 9944-treated rats with cholesterol had an obvious preventive action on fetal malformations. When cholesterol was added to the diet the same day as AY 9944 treatment and maintained until d 15, the prevention of malformations was almost complete. When the supplementation was initiated later, the prevention of anomalies decreased. The nature of plasma maternal sterols shows that the cholesterol supplementation modifies significantly the ratio of cholesterol to 7-dehydrocholesterol in treated rats. Therefore, maternal plasma sterol perturbations may play a role in the teratogenic action of AY 9944.

Association of microwaves and ionizing radiation: potentiation of teratogenic effects in the rat

Pregnant Wistar rats were exposed to either microwave-induced hyperthermia or gamma radiation or a combination of both. In microwave-induced hyperthermia, a core temperature of 42 degrees C was slightly teratogenic and a core temperature greater than or equal to 43 degrees C was highly teratogenic. Gamma radiation at 40 cGy was subteratogenic, while a dose of 75 cGy was highly teratogenic. A combination of microwave-induced hyperthermia up to 42 degrees C with 40 cGy of gamma radiation was highly teratogenic, indicating a mutual potentiation of the embryotoxic action of these two teratogens.

Semen analysis in Hodgkin's disease before the onset of treatment

A spermogram was performed before treatment in 57 young patients with Hodgkin's disease. The mean results were normal, and similar to those reported in fertile populations. Nineteen patients had an abnormal spermogram; 12 of these men had had fever recently or were febrile at the time of the exam. When the temperature was below 38.5 degrees C, there was only asthenospermia. With a higher temperature, semen anomalies were more severe, with oligoasthenospermia or even azoospermia. Only five febrile men had a normal spermogram, and all had slight fevers. Therefore, semen anomalies noted in about one third of patients with Hodgkin's disease are probably not due to a disease specific gonadal alteration, but can be attributed to fever which gonadal effects have been recognized for a long time and are well-documented.

[The fetal hydantoin syndrome (author's transl)]

Two siblings have various congenital malformations due to the teratogenic effect of anticonvulsant drugs. Their mother has a 14-year history of continuous anticonvulsant medication. The malformations noted in the older girl are less and in the 8 years younger sister more extensively developed as well as in the fetal hydantoin syndrome. The causes of different severity of the fetal hydantoin syndrome in two sisters are discussed.
