A substantial number of rheumatology patients are receiving excess starting and maintenance doses of hydroxychloroquine despite the existence of dosing guidelines, a group of ophthalmologists has reported.

The report raises some concerns because hydroxychloroquine has well-established ocular side effects and toxicities that makes screening by a ophthalmologist necessary for all patients on long-term therapy.

Rebekah A. Braslow, MD, and her colleagues in the division of ophthalmology at NorthShore University HealthSystem in Illinois conducted a retrospective review of the records of 554 rheumatology patients who were prescribed hydroxychloroquine during 2009-2016 and seen by a NorthShore ophthalmologist. They found that about half of the patients were on excess initial doses of the disease-modifying antirheumatic drug, according to retinal toxicity guidelines published by the American Academy of Ophthalmology (AAO) in 2011. There was no difference in the percentage of patients on an excess starting dose before the 2011 guidelines were published (54% of 92 patients) or after (49% of 462). The maintenance dose 1 year after beginning treatment was the same as the starting dose in 84% of patients, with reductions in 7% and increases in 9% (Ophthalmology. 2017 Jan 30. doi: 10.1016/j.ophtha.2016.12.021).

The AAO revised the guidelines in 2016 to define excess doses of hydroxychloroquine as greater than 5.0 mg/kg of actual body weight (Ophthalmology. 2016;123:1386-94). Based on these new guidelines, the investigators found that 56% of 527 patients who were currently receiving hydroxychloroquine were taking excess doses, and 43% of the 527 patients were still receiving doses that are more than 50 mg in excess of the calculated target dose that is recommended by the guidelines.

“The published ophthalmology screening guidelines have had no appreciable impact on clinical practice, highlighting a persistent deficiency in patient care and a significant medico-legal risk,” they concluded.

“Our findings are particularly concerning given that choosing a proper starting dose is the single safest, simplest, and most cost-effective measure available,” they wrote.

According to the authors, there were several reasons for the widespread inaccurate dosing. Firstly, the guidelines were published in ophthalmology literature and were therefore unlikely to be seen by rheumatologists. Secondly, the formulation of the drug, currently available only in 200-mg tablet form, made it difficult to adjust doses according to a patient’s weight.

This particular issue could be addressed if the drug manufacturers expanded formulation options, or by alternating daily dosing regimens or involving compound pharmacies, they suggested.

System-wide education and prompts via electronic medical records would also go some way toward ensuring that patients are prescribed the correct dose, they added.

The study was supported by intramural research funds within the division of ophthalmology in NorthShore University Health System.

People with incomplete lupus erythematosus exhibit nearly as many disease-related symptoms as do those with systemic lupus erythematosus and often receive many of the same treatments, according to findings reported from a cohort study of 3,837 patients registered with the Lupus Family Registry and Repository.

The study found that while individuals with incomplete lupus erythematosus (ILE) generally have fewer biomarkers of lupus, a subset are at risk of permanent organ damage and may transition to systemic lupus erythematosus (SLE).

“No risk stratification protocols or treatment recommendations for ILE currently exist, and clinical care is largely derived from SLE experience, in part due to the lack of consensus on what constitutes ILE,” wrote Teresa Aberle of the Oklahoma Medical Research Foundation, Oklahoma City, and her coauthors.

The treatments that ILE patients received also ran the gamut from hydroxychloroquine and steroids to immunosuppressants of varying potency.

The investigators classified participants as having ILE if they met three of the 1997 American College of Rheumatology SLE classification criteria, and were classified as having SLE if they met four or more of those criteria. Overall, 440 individuals had ILE and 3,397 had SLE, with ILE patients on average older than SLE patients and less likely to be African American (Arthritis Care Res. 2017 Jan 24. doi: 10.1002/acr.23201).

Among those with ILE, 97.3% were ANA positive, compared with 99.3% of patients with SLE, but fewer ILE patients had ANA titers of 1:1,080 or higher (10.5% vs. 19.5%; odds ratio, 2.03; P less than .0001). ILE patients were also more than three times less likely to show anti-dsDNA antibodies than were SLE patients, but a similar percentage – approximately 42% – of both groups had anti-cardiolipin antibodies.

The researchers also examined plasma levels of B-lymphocyte stimulator, hypothesizing that lower antibody levels and fewer autoantibody specificities in ILE patients might connect with autoantibody production. In a subset of 72 ILE patients, 100 SLE patients, and 172 healthy controls, they observed that median B-lymphocyte stimulator levels were significantly lower in ILE patients, compared with SLE patients, although they were still higher than those in healthy controls. Around one-third of ILE patients had B-lymphocyte stimulator levels that exceeded the positive cutoff value, compared with 54% of SLE patients and 9% of healthy controls.

When it came to symptoms, the researchers found that each lupus classification criterion was seen in at least some ILE patients, although SLE patients were significantly more likely to have protein in urine (65.1% vs. 50%; OR, 1.9; P less than .0001), low blood counts (76.6% vs. 66%; OR, 1.7; P less than .0001), and experience seizures (19.4% vs. 14.4%; OR, 1.4; P = .012). Patients with SLE were also more likely to have pleurisy (58.2% vs. 51.9%; P = .012) and exhibit rapid hair loss (52.2% vs. 47.2%; P = .049) than were those with ILE.

Nearly one in five patients with ILE were affected by at least one clinical criterion of the disease linked to multiple indicators of disease severity, which included criteria such as serositis, renal symptoms, neurologic symptoms, hemolytic anemia, and thrombocytopenia. The investigators also noted that African Americans with ILE showed a higher rate of major clinical manifestations than did European Americans with ILE (25.7% vs. 14.9%).

“Given the association between renal disease and future transition to classified SLE, these observations suggest that patients of non-European American ancestry would likely benefit from careful monitoring and inclusion in future longitudinal studies of early or incomplete lupus,” they wrote.

While ILE patients used fewer medication types and were less likely to have used each type of medication, 65.2% of them had been treated with hydroxychloroquine and 70.7% had been treated with steroids. More than a quarter of ILE patients had used immunosuppressants and 14.8% had used major immunosuppressants, such as mycophenolate mofetil and cyclophosphamide.

“These results show that in clinical practice, ILE is often treated with hydroxychloroquine and/or steroids and occasionally may warrant treatment with potent immunosuppressants,” the authors wrote.

The authors also noted that while some patients with ILE have more severe clinical presentations and require more aggressive treatments, others with less severe disease who are at low risk of transitioning to SLE may be at risk of overtreatment.

“These results reinforce the need for new strategies to personalize disease management in ILE based on individual presentation and risk factors.”

The National Institutes of Health and the U.S. Department of Veterans Affairs supported the study. One author reported grants from pharmaceutical companies outside of the submitted work, and there were no other conflicts of interest declared.

WAILEA, HAWAII – Using larger doses and avoiding overarching of the brows are among the considerations to keep in mind when using neuromodulators in men, advised Canadian dermatologist Katie Beleznay, MD.

In general, men have a very different anatomy with a different brow position, and have needs different from those of women, said Dr. Beleznay of the University of British Columbia, Vancouver.

One secret for successful injections of toxins in male patients: Dose matters. Men have stronger muscles in the face and need larger doses to overcome their muscular strength, Dr. Beleznay said in a video interview at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.

On average, “if you use 20-30 units in a female glabella, maybe you’d use 40-50, maybe even 60 units in a male patient,” she said. However, the volume depends on the strength of the muscles in the area, and some men may need less to avoid a frozen look. “You can always treat less and bring them back in a couple of weeks and add more,” especially with patients who are new to treatment, Dr. Beleznay noted.

She disclosed financial relationships with Allergan, Revance, Evolus, Galderma, and Zeltiq.

WAILEA, HAWAII – A study that used patient-reported outcomes to assess the impact of different contraceptive methods on acne provided “fascinating results,” Lawrence F. Eichenfield, MD, said at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation.

“Progestins are present in birth control for the birth control, but they’re not usually good for the acne,” Dr. Eichenfield said in a video interview at the meeting.

Dr. Eichenfield, professor of dermatology and pediatrics at the University of California, San Diego, and his colleagues reviewed patient reports from an Internet-based survey of more than 2,000 adolescent and young adult acne patients asking whether they were on any contraceptive, and if so, how they thought the contraceptive method affected their acne.

Overall, hormonal progestin-only IUDs and some progestin-only implants correlated with worse acne. Of the combined oral contraceptives, those on the OCs containing drospirenone performed best, he said. Also of interest, the triphasic OCs, with the progestin in three phases, had a better impact on the acne than did the dual ones, he added.

The review of patient-reported outcomes can not only inform clinicians on how they should prescribe hormonal therapy, but also raises awareness of the impact of contraceptives on acne in general, Dr. Eichenfield said.

The results were published last year (J Drugs Dermatol. 2016 Jun 1;15[6]:670-4).

Dr. Eichenfield disclosed relationships with Anacor/Pfizer, Genentech, Lilly, Regeneron/Sanofi, Medimetriks, and Otsuka.

For some veterans, exposure to Agent Orange and its many health ramifications is an ongoing concern—even though they might have been exposed more than 50 years ago. Clinicians from Sinai Hospital of Baltimore in Maryland report on a patient who reminded them that a current illness could be related to that long-ago exposure.

Related: Bladder Cancer and Hyperthyroidism Linked to Agent Orange

The 69-year-old man came to their clinic with a painful, enlarging mass of the right lateral thigh, which ultrasound revealed as a myxofibrosarcoma. He underwent radical excision of the sarcoma with adjuvant radiotherapy. Histologic examination revealed an 8.3 cm, grade 3 pleomorphic liposarcoma. The patient asked, “Was it related to Agent Orange?” It may have been, the clinicians decided.

Agent Orange tends to accumulate in the liver and adipose tissue; it also affects lipid metabolism and may lead to hyperlipidemia. Although in the early days after the Vietnam War, many pathologies were labeled as “stress induced,” a number of illnesses have since been linked to Agent Orange, including B-cell leukemia, Hodgkin and non-Hodgkin lymphoma, prostate cancer, and, perhaps, multiple myeloma. But the authors say the toxin’s role in sarcomagenesis has been controversial in part because of conflicting case-control studies and because large-scale clinical trials are not feasible.

There has been no well-established precipitating factor for liposarcoma, the authors note. But they suggest that clinicians should have a high degree of suspicion for persistent and evolving soft tissue masses in patients with a previous military background, which should prompt the search for a possible toxin exposure.

Their patient experienced the enlarging soft tissue mass over the course of a year. A simple question: “Have you ever been in the military or had any previous wartime toxin exposure?” early on would have impelled the physicians to do a swifter workup, the authors say, particularly in a case with high risk of metastasis and poor prognosis. The patient will continue to be monitored “for years,” the authors say.

“While these days we have access to a vast amount of diagnostic tests and imaging,” the authors conclude, “one cannot underestimate the importance of understanding a patient’s past history.”

SAN FRANCISCO—Interim results of a phase 3 trial suggest 2 treatment regimens may provide comparable efficacy in patients with extranodal natural killer/T-cell lymphoma (ENKTL), though 1 regimen appears more toxic than the other.

In this ongoing trial, investigators are comparing pegaspargase, gemcitabine, oxaliplatin, and thalidomide (P-Gemox+Thal) to pegaspargase, methotrexate, calcium folinate, and dexamethasone (AspaMetDex).

In some patients, either regimen may be followed by extensive involved-field radiotherapy (EIFRT) or autologous hematopoietic stem cell transplant (ASCT).

Thus far, P-Gemox+Thal and AspaMetDex have proven similarly effective for patients with newly diagnosed, stage I/II ENKTL.

And both regimens have produced unsatisfying survival outcomes in patients with advanced or relapsed/refractory ENKTL, according to investigator Huiqiang Huang, MD, of Sun Yat-sen Institute of Hematology in Guangzhou, China.

In addition, P-Gemox+Thal seems to be less toxic, overall, than AspaMetDex.

However, Dr Huang said it is still too early to draw any firm conclusions about these regimens. 

He presented results from this trial at the 9th Annual T-cell Lymphoma Forum. Results were previously presented at the 2016 ASH Annual Meeting (abstract 1819).

Dr Huang noted that AspaMetDex and SMILE (dexamethasone, methotrexate, ifosfamide, lL-asparaginase, and etoposide) are frequently administered to patients with ENKTL. And P-Gemox is recommended in the 2016 NCCN guidelines.

“But optimal regimens still have not been fully defined,” he said.

Therefore, he and his colleagues decided to compare AspaMetDex to P-Gemox+Thal in this non-inferiority trial, which has enrolled 110 patients from 12 centers in China.

Treatment

Fifty-six patients have been randomized to receive P-Gemox+Thal. Every 3 weeks, they received pegaspargase at 2000 U/m² on day 1, gemcitabine at 1000 mg/m² on days 1 and 8, and oxaliplatin at 130 mg/m² on days 1 and 8. They also received thalidomide at 100 mg every day for 1 year.

Fifty-four patients have been randomized to receive AspaMetDex. Every 3 weeks, they received pegaspargase at 2000 U/m² on day 1, methotrexate at 3000 mg/m² on day 1, calcium folinate at 30 mg every 6 hours until a safe serum methotrexate concentration was reached, and dexamethasone at 40 mg every day on days 1 to 4.

Newly diagnosed patients with stage I/II disease received either regimen as induction for a maximum of 4 cycles. Responders went on to receive EIFRT at 56 Gy in 28 fractions over 4 weeks.

Patients with newly diagnosed, stage III/IV ENKTL or relapsed/refractory ENKTL received either chemotherapy regimen for a maximum of 6 cycles. If they achieved a complete response (CR), these patients could proceed to ASCT.

Stage I/II ENKTL

Of the 63 stage I/II patients, 33 were randomized to P-Gemox+Thal, and 30 received AspaMetDex. In both arms, most patients were male (69.7% and 70%, respectively) and younger than 60 (78.8% and 90%, respectively).

Ninety-seven percent of patients in the P-Gemox+Thal arm had an ECOG status of 0-1, as did 100% of patients in the AspaMetDex arm.

The overall response rate (ORR) was 85.2% in the P-Gemox+Thal arm and 81.5% in the AspaMetDex arm. The CR rate was 59.3% in both arms. The rate of stable disease was 3.7% in the P-Gemox+Thal arm and 11.1% in the AspaMetDex arm.

After EIFRT, the ORR increased to 92.6% in the P-Gemox+Thal arm, and the CR rate increased to 88.8%. In the AspaMetDex arm, the ORR increased to 88.8%, and the CR rate increased to 85.1%.

At a median follow-up of 13.5 months, the 2-year progression-free survival rate was 82.9% in the P-Gemox+Thal arm and 84.5% in the AspaMetDex arm (P=0.791).

The 2-year overall survival rates were 95.0% in the P-Gemox+Thal arm and 75.8% in the AspaMetDex arm (P=0.089).

Advanced, rel/ref ENKTL

Of the 47 patients with stage III/IV or relapsed/refractory ENKTL, 24 were randomized to P-Gemox+Thal, and 23 to AspaMetDex. In both arms, most patients were male (75% and 87%, respectively) and younger than 60 (95.8% and 91.3%, respectively).

ECOG status was 0 for 62.5% of patients in the P-Gemox+Thal arm and 73.9% of those in the AspaMetDex arm. ECOG status was 1 for 33.3% and 17.4%, respectively.

The ORR was 86.3% in the P-Gemox+Thal arm and 70% in the AspaMetDex arm. The CR rate was 50% in both arms.

The partial response rate was 36.3% in the P-Gemox+Thal arm and 20% in the AspaMetDex arm. And the rate of stable disease was 13.6% and 15%, respectively.

Three patients in each treatment arm went on to ASCT after CR. A total of 3 patients relapsed within 6 months of ASCT—2 in the P-Gemox+Thal arm and 1 in the AspaMetDex arm. Two patients died of disease progression.

At a median follow-up of 14.5 months, the 2-year progression-free survival was 12.2 months in the P-Gemox+Thal arm and 7.6 months in the AspaMetDex arm (P=0.365).

The 2-year overall survival was 52.5% in the P-Gemox+Thal arm and 48.9% in the AspaMetDex arm (P=0.935).

Overall safety

Rates of leukopenia, thrombocytopenia, and ALT/AST increase were all significantly higher with P-Gemox+Thal than with AspaMetDex—100% vs 66.7% (P<0.001), 64.2% vs 35.2% (P=0.005), and 69.6% vs 64.8% (P=0.004), respectively.

Rates of anemia and edema were significantly higher with AspaMetDex than with P-Gemox+Thal—51.8% vs 77.8% (P=0.005) and 37.5% vs 66.7% (P=0.003), respectively.

There were 3 treatment-related deaths in the AspaMetDex arm but none in the P-Gemox+Thal arm. Two of the treatment-related deaths—from severe acute renal failure and sepsis—occurred in the first cycle, and 1 death—due to severe sepsis—occurred in the third cycle.

The median hospitalization time was significantly shorter in the P-Gemox+Thal arm than the AspaMetDex arm—1.9 days and 4.9 days, respectively (P<0.01).

Based on these results, Dr Huang said P-Gemox+Thal may be more tolerable and provide more convenient administration than AspaMetDex.

Dr Huang noted that AspaMetDex and SMILE (dexamethasone, methotrexate, ifosfamide, lL-asparaginase, and etoposide) are frequently administered to patients with ENKTL. And P-Gemox is recommended in the 2016 NCCN guidelines.

“But optimal regimens still have not been fully defined,” he said.

Therefore, he and his colleagues decided to compare AspaMetDex to P-Gemox+Thal in this non-inferiority trial, which has enrolled 110 patients from 12 centers in China.

Treatment

Fifty-six patients have been randomized to receive P-Gemox+Thal. Every 3 weeks, they received pegaspargase at 2000 U/m² on day 1, gemcitabine at 1000 mg/m² on days 1 and 8, and oxaliplatin at 130 mg/m² on days 1 and 8. They also received thalidomide at 100 mg every day for 1 year.

Fifty-four patients have been randomized to receive AspaMetDex. Every 3 weeks, they received pegaspargase at 2000 U/m² on day 1, methotrexate at 3000 mg/m² on day 1, calcium folinate at 30 mg every 6 hours until a safe serum methotrexate concentration was reached, and dexamethasone at 40 mg every day on days 1 to 4.

Newly diagnosed patients with stage I/II disease received either regimen as induction for a maximum of 4 cycles. Responders went on to receive EIFRT at 56 Gy in 28 fractions over 4 weeks.

Patients with newly diagnosed, stage III/IV ENKTL or relapsed/refractory ENKTL received either chemotherapy regimen for a maximum of 6 cycles. If they achieved a complete response (CR), these patients could proceed to ASCT.

Stage I/II ENKTL

Of the 63 stage I/II patients, 33 were randomized to P-Gemox+Thal, and 30 received AspaMetDex. In both arms, most patients were male (69.7% and 70%, respectively) and younger than 60 (78.8% and 90%, respectively).

Ninety-seven percent of patients in the P-Gemox+Thal arm had an ECOG status of 0-1, as did 100% of patients in the AspaMetDex arm.

The overall response rate (ORR) was 85.2% in the P-Gemox+Thal arm and 81.5% in the AspaMetDex arm. The CR rate was 59.3% in both arms. The rate of stable disease was 3.7% in the P-Gemox+Thal arm and 11.1% in the AspaMetDex arm.

After EIFRT, the ORR increased to 92.6% in the P-Gemox+Thal arm, and the CR rate increased to 88.8%. In the AspaMetDex arm, the ORR increased to 88.8%, and the CR rate increased to 85.1%.

At a median follow-up of 13.5 months, the 2-year progression-free survival rate was 82.9% in the P-Gemox+Thal arm and 84.5% in the AspaMetDex arm (P=0.791).

The 2-year overall survival rates were 95.0% in the P-Gemox+Thal arm and 75.8% in the AspaMetDex arm (P=0.089).

Advanced, rel/ref ENKTL

Of the 47 patients with stage III/IV or relapsed/refractory ENKTL, 24 were randomized to P-Gemox+Thal, and 23 to AspaMetDex. In both arms, most patients were male (75% and 87%, respectively) and younger than 60 (95.8% and 91.3%, respectively).

ECOG status was 0 for 62.5% of patients in the P-Gemox+Thal arm and 73.9% of those in the AspaMetDex arm. ECOG status was 1 for 33.3% and 17.4%, respectively.

The ORR was 86.3% in the P-Gemox+Thal arm and 70% in the AspaMetDex arm. The CR rate was 50% in both arms.

The partial response rate was 36.3% in the P-Gemox+Thal arm and 20% in the AspaMetDex arm. And the rate of stable disease was 13.6% and 15%, respectively.

Three patients in each treatment arm went on to ASCT after CR. A total of 3 patients relapsed within 6 months of ASCT—2 in the P-Gemox+Thal arm and 1 in the AspaMetDex arm. Two patients died of disease progression.

At a median follow-up of 14.5 months, the 2-year progression-free survival was 12.2 months in the P-Gemox+Thal arm and 7.6 months in the AspaMetDex arm (P=0.365).

The 2-year overall survival was 52.5% in the P-Gemox+Thal arm and 48.9% in the AspaMetDex arm (P=0.935).

Overall safety

Rates of leukopenia, thrombocytopenia, and ALT/AST increase were all significantly higher with P-Gemox+Thal than with AspaMetDex—100% vs 66.7% (P<0.001), 64.2% vs 35.2% (P=0.005), and 69.6% vs 64.8% (P=0.004), respectively.

Rates of anemia and edema were significantly higher with AspaMetDex than with P-Gemox+Thal—51.8% vs 77.8% (P=0.005) and 37.5% vs 66.7% (P=0.003), respectively.

There were 3 treatment-related deaths in the AspaMetDex arm but none in the P-Gemox+Thal arm. Two of the treatment-related deaths—from severe acute renal failure and sepsis—occurred in the first cycle, and 1 death—due to severe sepsis—occurred in the third cycle.

The median hospitalization time was significantly shorter in the P-Gemox+Thal arm than the AspaMetDex arm—1.9 days and 4.9 days, respectively (P<0.01).

Based on these results, Dr Huang said P-Gemox+Thal may be more tolerable and provide more convenient administration than AspaMetDex.

A gene therapy known as DTX101 has shown early promise for the treatment of adults with hemophilia B, according to the company developing the therapy.

DTX101 is designed to deliver stable expression of factor IX (FIX) in patients with hemophilia B.

Preliminary results from a phase 1/2 trial showed that DTX101 can increase FIX expression in these patients, allowing some to forgo prophylactic and on-demand treatment.

However, 5 of the 6 patients enrolled in this trial experienced elevations in alanine aminotransferase (ALT), with 1 patient experiencing a grade 4 adverse event as a result.

These results were released by Dimension Therapeutics, Inc., the company developing DTX101.

DTX101 is a non-replicating, recombinant adeno-associated viral vector, AAVrh10, with a codon-optimized FIX gene expressing wild-type FIX protein.

The phase 1/2 study of DTX101 has enrolled 6 patients, ages 28 to 70, with moderate/severe to severe hemophilia B. They had baseline FIX expression of ≤ 2%, which requires either prophylactic or on-demand recombinant FIX therapy.

These 6 patients were divided into 2 dose cohorts. Cohort 1 (n=3) received DXT101 at 1.6 x 10¹² GC/kg. And cohort 2 (n=3) received 5 x 10¹² GC/kg.

All patients have been in post-treatment follow-up ranging from 6 weeks to 52 weeks.

Efficacy

Researchers observed evidence of efficient liver transduction of DTX101 across the 2 cohorts.

Patients in the low-dose cohort achieved peak FIX expression levels of 10% to 11%, which stabilized to between 3% and 4% at last follow-up (weeks 24, 48, and 52).

Patients in the second dose cohort achieved peak FIX expression of 13%, 20%, and 12% at weeks 4, 8, and 8, respectively. FIX activity was 5% and 8% in 2 patients at 12 weeks of follow-up. It was 7% for the third patient at 7 weeks.

None of the patients in cohort 2 have required prophylactic or on-demand recombinant FIX therapy for spontaneous bleeds post-dosing.

Safety

None of the patients experienced a drug-related serious adverse event as of the January 28, 2017, data cutoff.

Five of the 6 patients had elevations in ALT. All elevated liver enzymes were clinically asymptomatic with no elevations of gamma-glutamyl transferase, alkaline phosphatase, or bilirubin.

Patient 3 in cohort 2 experienced a grade 4 adverse event due to an elevated laboratory ALT (defined as > 800 IU/L).

Preliminary findings from 2 patients in each cohort prompted the administration of a standard tapering course of corticosteroids to treat mild, asymptomatic elevations in ALT (52-98 IU/L).

The third patient in cohort 2 also received corticosteroids, experiencing a peak ALT of 914 IU/L, and was at 431 IU/L at 6 weeks post-dosing.

As of the January 28, 2017, data cutoff, 2 of 3 patients in cohort 2 had ALT levels in the normal range. Cohort 1 patients were all clinically stable and off steroids, with ALT levels in the normal range.

Dimension Therapeutics said it expects cohort 2 will continue to receive a standard tapering course of corticosteroid therapy.

As required by the trial protocol, the company reported the ALT levels for patient 3 in cohort 2 to the Data Safety Monitoring Committee, the US Food and Drug Administration, and the appropriate regulatory authorities.

The company said it will await their feedback prior to initiating dosing of cohort 3.

“We are encouraged by the apparent efficiency of gene transduction and the early trend we are seeing in sustained FIX activity across both cohorts with our wild-type FIX AAVrh10 vector in patients,” said Annalisa Jenkins, MBBS, chief executive officer of Dimension Therapeutics.

“We continue to explore the therapeutic window for DTX101 as our data mature and in light of the ALT rises that appear to be associated with a decline in FIX activity.”

AMSTERDAM—New research suggests some generic cancer drugs could be manufactured for less than 1% of the prices currently charged in the US and UK.

For example, researchers calculated that manufacturing a 400 mg tablet of imatinib costs $0.92.

Charging $1.04 per tablet would cover costs and allow for a 10% profit margin.

However, the current price of imatinib is $84.36 per tablet in the UK and $247.74 per tablet in the US.

Melissa Barber, of the London School of Hygiene and Tropical Medicine in the UK, reported these findings at ECCO 2017: European Cancer Congress (abstract 1032).

Barber and her colleagues collected data on per-kilogram costs of exported active pharmaceutical ingredients (APIs) from an online database of Indian export logs.

The team then estimated generic prices for tablets through an established costing algorithm. They calculated per-dose API costs and added excipient costs of $2.63 per kg of finished pharmaceutical product and per-tablet costs of production of $0.01, plus a 10% profit margin accounting for a 26.6% average tax on profits (assuming manufacture in India.)

Finally, the researchers compared the calculated price to current unit prices in the US, UK, Spain, and India.

For imatinib, the team determined the cost of the API to be $2284 per kg and the API cost per tablet to be $0.91. They then added excipient cost ($0.002 per tablet), conversion cost ($0.01 per tablet), and a 10% profit margin accounting for a 26.6% tax on profits.

This resulted in the estimated generic price of $1.04 per tablet. The per-tablet price is below the estimated price in India ($0.22) but much higher than the estimated price in Spain ($57.53), the UK ($84.36), and the US ($247.74).

Barber noted that, according to her group’s calculations, imatinib could be produced for $54 a month.

Another drug that could be produced for a low cost is etoposide. Barber and her colleagues calculated a generic price for etoposide of $0.97 per 100 mg tablet.

However, the per-tablet price is $1.50 in India, $8.65 in Spain, $11.34 in the UK, and $87.14 in the US.

The researchers calculated a generic price for mercaptopurine of $0.03 per 50 mg tablet, which is the same as the per-tablet price in India. However, a 50 mg mercaptopurine tablet costs $3.14 in Spain, $2.56 in the UK, and $0.40 in the US.

“Showing that certain cancers could be treated for very low prices could transform the future of people with these cancers in very low-income countries where there are usually few or no treatment options,” Barber said.
