Much-anticipated results from the National Institute of Allergy and Infectious Diseases’ clinical trial of remdesivir in COVID-19 patients published in the New England Journal of Medicine suggest remdesivir shortens the disease course for hospitalized COVID-19 patients.

The agency reported initial promising results from the study earlier this month, which prompted the Food and Drug Administration to issue an emergency use authorization (EUA) for the drug, but the full data and results have not been widely available until now.

In the study of 1,063 patients, the researchers found patients who received a 10-day course of remdesivir had a reduced recovery time of 11 days, compared with 15 days to recovery in the group that received a placebo. The findings also suggest remdesivir should be started, if possible, before patients have such severe pulmonary disease that they require mechanical ventilation, according to the study authors.

The published results are “completely consistent” with the NIAID’s earlier announcement, H. Clifford Lane, MD, deputy director for clinical research and special projects at the NIAID, said in an interview. “The benefit appeared to be the greatest for the patients who are hospitalized with severe disease who require supplemental oxygen.”

Given the limited supply of remdesivir, physicians have been eager to see the full data to ensure they use the drug most effectively, Daniel Kaul, MD, a professor of infectious diseases at the University of Michigan, Ann Arbor, said in an interview. Hospitals in states across the country, including New York, Michigan, and Washington, have received limited supplies of the drug in the last couple of weeks since the FDA’s authorization.

“I am losing my patience waiting for #remdesivir data. I was willing to give them a week to verify the numbers, triple proof the tables, cautiously frame conclusions. But it’s gone on too long. We are rationing with no rationale. We are floating on whisps [sic] of data, adrift,” Kate Stephenson, MD, an infectious diseases specialist at the Center for Virology and Vaccine Research at Harvard Medical School, Boston, wrote on Twitter May 18. After reading the paper, she tweeted Friday evening that she was “relieved to see convincing benefit – I was starting to worry!”

In the midst of a public health crisis, however, it is not unusual to make an announcement about trial results before the full dataset has been analyzed, said Dr. Lane. The NIAID followed a similar playbook for the PALM trial evaluating possible Ebola treatments in the Democratic Republic of Congo, with the independent monitoring board recommending the trial be terminated early in response to positive results from two of the four candidate drugs.

“When you have a result you think is of public health importance, you don’t wait for it to be published in a peer-reviewed journal,” said Dr. Lane, a coauthor of the study. The lag time from announcement to study publication was a result of the time it took to write up the paper for publication and go through peer review, Dr. Lane added. He also noted that the FDA had access to the data when the agency wrote its guidance for physicians administering the drug to patients under the EUA.

The authors opted not to publish the initial findings on a preprint server because they felt it was important to undergo peer review, said Dr. Lane. “The last thing you want for something this critical is for incomplete data to be out there, or you don’t have everything audited to the level that you want.”

 

Trial details

In the ACTT-1 randomized, placebo-controlled, double-blinded trial, researchers enrolled 1,063 patients from Feb. 21 to April 19, 2020, at 60 trial sites and 13 subsites worldwide (45 sites in the United States). The remdesivir group had 541 patients, and the placebo group had 522. A small number of patients (49 in the remdesivir group and 53 in the placebo group) discontinued treatment before day 10 because of an adverse event or withdrawn consent. When data collection for this preliminary analysis ended in late April, 301 patients had not recovered and had not completed their final follow-up visit.

Most of the patients had one (27%) or more (52.1%) preexisting conditions, including hypertension (49.6%), obesity (37%), and type 2 diabetes mellitus (29.7%). Mean patient age was 58.9 years, and the majority of patients were men (64.3%). The median number of days from symptom onset to randomization was 9, and 53.6% of the patients were white, 20.6% were black, 12.6% were Asian, 23.4% were Hispanic or Latino, and the ethnicity of 13.6% were not reported or reported as other.

Patients received one 200-mg loading dose on the first day of the trial, and then one 100-mg maintenance dose every day for days 2 through 10, or until discharge or death. Patients in the control group of the study received a matching placebo on the same schedule and volume. The clinical status of each patient was assessed every day, from day 1 through day 29 of his or her hospital stay, according to an eight-category ordinal scale.

Time to recovery was defined as the first day during the 28-day enrollment period that a patient’s clinical status met a 1 (not hospitalization, no activity limitations), 2 (not hospitalized, activity limitation, oxygen requirement or both), or 3 (hospitalized, not requiring supplemental oxygen or medical care if hospitalization was extended for infection-control reasons) on the eight-category scale. A score of 4 indicated a patient was hospitalized and needed ongoing medical care, but did not require supplemental oxygen; a score of 8 signified death.

The analysis found remdesivir patients had a median time to recovery of 11 days, compared with the median 15 days for patients on the placebo (rate ratio for recovery, 1.32; 95% confidence interval, 1.12-1.55; P < .001). Mortality was also lower in the remdesivir group (hazard ratio for death, 0.70; 95% CI, 0.47-1.04), but the result was not statistically significant. By 14 days, the Kaplan-Meier estimate of mortality was 7.1 % in the remdesivir group and 11.9% in the placebo group.

Patients receiving oxygen, but not yet requiring high-flow oxygen, mechanical ventilation, or extracorporeal membrane oxygenation, seemed to fare best from treatment with remdesivir (these patients had a baseline ordinal score of 5). That may be a result of the larger sample size of these patients, the researchers note in the study. The study authors were unable to estimate the recovery time for the most severely ill patients (category 7), possibly because the follow-up time was too short to fully evaluate this subgroup.

“There is clear and consistent evidence of clinically significant benefit for those hospitalized on oxygen but not yet requiring mechanical ventilation,” Dr. Kaul, who was not involved in the study, said after seeing the published results. “Surprisingly, early dosing as measured from time to onset of symptoms did not seem to make a difference.”

Dr. Kaul said there is still the possibility that remdesivir could benefit patients on mechanical ventilation, but “clinicians will have to determine if the evidence suggesting no benefit in those who are intubated is strong enough to justify using this currently scarce resource in that population versus limiting use to those requiring oxygen but not on mechanical ventilation.”

Site investigators estimated that just four serious adverse events (two in each group) in enrolled patients were related to remdesivir or placebo. No deaths were attributed to the treatments, although acute respiratory failure, hypotension, acute kidney injury, and viral pneumonia were slightly more common in patients receiving the placebo than those receiving remdesivir.

The researchers plan to publish a follow-up study in the coming weeks or months, after the full cohort has completed 28 days of follow-up, Dr. Lane said. In future studies, the agency will likely focus on comparing remdesivir with combinations of remdesivir with other treatments, like the anti-inflammatory baricitinib.

Chiesi Global Rare Diseases announced that the Food and Drug Administration has approved a new formulation of deferiprone (Ferriprox) for the treatment of patients with transfusional iron overload caused by thalassemia syndromes when current chelation therapy is inadequate. The new formulation of twice-a-day Ferriprox 1,000 mg oral tablets eliminates the midday dose, according to a company press release.

“A treatment option that reduces serum ferritin, cardiac iron, and liver iron with an established safety profile and now twice-a-day tablet dosing can represent a significant advantage for patients,” stated Thomas Coates, MD, in the press release. Dr. Coates is the section head of hematology at Children’s Hospital Los Angeles.

Deferiprone was originally approved by the FDA in 2011 for the treatment of transfusional iron overload caused by thalassemia syndromes. Ferriprox contains a label warning that it can cause agranulocytosis that can lead to serious infections and death. As neutropenia may precede the development of agranulocytosis, the warning advises measurement of the absolute neutrophil count before starting Ferriprox and monitoring the ANC weekly on therapy. In addition, Ferriprox should be interrupted if infection develops, and the ANC should be monitored more frequently.

As Ferriprox can cause fetal harm, women of reproductive potential should be advised to use an effective method of contraception during treatment and for at least 6 months after the last dose, according to the company release.

The Food and Drug Administration approved olaparib (Lynparza, AstraZeneca) for deleterious or suspected deleterious germline or somatic homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC).

The drug is limited to use in men who have progressed following prior treatment with enzalutamide or abiraterone.

Olaparib becomes the second PARP inhibitor approved by the FDA for use in prostate cancer this week. Earlier, rucaparib (Rubraca, Clovis Oncology) was approved for use in patients with mCRPC that harbor deleterious BRCA mutations (germline and/or somatic).

Olaparib is also indicated for use in ovarian, breast, and pancreatic cancers.

The FDA also approved two companion diagnostic devices for treatment with olaparib: the FoundationOne CDx test (Foundation Medicine) for the selection of patients carrying HRR gene alterations and the BRACAnalysis CDx test (Myriad Genetic Laboratories) for the selection of patients carrying germline BRCA1/2 alterations.

The approval was based on results from the open-label, multicenter PROfound trial, which randomly assigned 387 patients to olaparib 300 mg twice daily and to investigator’s choice of enzalutamide or abiraterone acetate. All patients received a GnRH analogue or had prior bilateral orchiectomy.

The study involved two cohorts. Patients with mutations in either BRCA1, BRCA2, or ATM were randomly assigned in cohort A (n = 245); patients with mutations among 12 other genes involved in the HRR pathway were randomly assigned in cohort B (n = 142); those with co-mutations were assigned to cohort A.

The major efficacy outcome of the trial was radiological progression-free survival (rPFS) (cohort A).

In cohort A, patients receiving olaparib had a median rPFS of 7.4 months vs 3.6 months among patients receiving investigator’s choice (hazard ratio [HR], 0.34; P < .0001). Median overall survival was 19.1 months vs 14.7 months (HR, 0.69; P = .0175) and the overall response rate was 33% vs 2% (P < .0001).

In cohort A+B, patients receiving olaparib had a median rPFS of 5.8 months vs 3.5 months among patients receiving investigator’s choice (HR, 0.49; P < .0001).

The study results were first presented at the 2019 annual meeting of the European Society for Medical Oncology. At that time, study investigator Maha Hussain, MD, Northwestern University, Chicago, said the rPFS result and other outcomes were a “remarkable achievement” in such heavily pretreated patients with prostate cancer.

Patients with prostate cancer should now undergo genetic testing of tumor tissue to identify the roughly 30% of patients who can benefit – as is already routinely being done for breast, ovarian, and lung cancer, said experts at ESMO.

The most common adverse reactions with olaparib (≥10% of patients) were anemia, nausea, fatigue (including asthenia), decreased appetite, diarrhea, vomiting, thrombocytopenia, cough, and dyspnea. Venous thromboembolic events, including pulmonary embolism, occurred in 7% of patients randomly assigned to olaparib, compared with 3.1% of those receiving investigator’s choice of enzalutamide or abiraterone.

Olaparib carries the warning that myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) occurred in <1.5% of patients exposed to it as a monotherapy, and that the majority of events had a fatal outcome.

The recommended olaparib dose is 300 mg taken orally twice daily, with or without food.

The most common adverse reactions with olaparib (≥10% of patients) were anemia, nausea, fatigue (including asthenia), decreased appetite, diarrhea, vomiting, thrombocytopenia, cough, and dyspnea. Venous thromboembolic events, including pulmonary embolism, occurred in 7% of patients randomly assigned to olaparib, compared with 3.1% of those receiving investigator’s choice of enzalutamide or abiraterone.

Olaparib carries the warning that myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) occurred in <1.5% of patients exposed to it as a monotherapy, and that the majority of events had a fatal outcome.

The recommended olaparib dose is 300 mg taken orally twice daily, with or without food.

The Food and Drug Administration approved olaparib (Lynparza, AstraZeneca) for deleterious or suspected deleterious germline or somatic homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC).

The drug is limited to use in men who have progressed following prior treatment with enzalutamide or abiraterone.

Olaparib becomes the second PARP inhibitor approved by the FDA for use in prostate cancer this week. Earlier, rucaparib (Rubraca, Clovis Oncology) was approved for use in patients with mCRPC that harbor deleterious BRCA mutations (germline and/or somatic).

Olaparib is also indicated for use in ovarian, breast, and pancreatic cancers.

The FDA also approved two companion diagnostic devices for treatment with olaparib: the FoundationOne CDx test (Foundation Medicine) for the selection of patients carrying HRR gene alterations and the BRACAnalysis CDx test (Myriad Genetic Laboratories) for the selection of patients carrying germline BRCA1/2 alterations.

The approval was based on results from the open-label, multicenter PROfound trial, which randomly assigned 387 patients to olaparib 300 mg twice daily and to investigator’s choice of enzalutamide or abiraterone acetate. All patients received a GnRH analogue or had prior bilateral orchiectomy.

The study involved two cohorts. Patients with mutations in either BRCA1, BRCA2, or ATM were randomly assigned in cohort A (n = 245); patients with mutations among 12 other genes involved in the HRR pathway were randomly assigned in cohort B (n = 142); those with co-mutations were assigned to cohort A.

The major efficacy outcome of the trial was radiological progression-free survival (rPFS) (cohort A).

In cohort A, patients receiving olaparib had a median rPFS of 7.4 months vs 3.6 months among patients receiving investigator’s choice (hazard ratio [HR], 0.34; P < .0001). Median overall survival was 19.1 months vs 14.7 months (HR, 0.69; P = .0175) and the overall response rate was 33% vs 2% (P < .0001).

In cohort A+B, patients receiving olaparib had a median rPFS of 5.8 months vs 3.5 months among patients receiving investigator’s choice (HR, 0.49; P < .0001).

The study results were first presented at the 2019 annual meeting of the European Society for Medical Oncology. At that time, study investigator Maha Hussain, MD, Northwestern University, Chicago, said the rPFS result and other outcomes were a “remarkable achievement” in such heavily pretreated patients with prostate cancer.

The Food and Drug Administration has expanded the approved indication for atezolizumab (Tecentriq) in patients with non–small cell lung cancer (NSCLC).

Atezolizumab is now approved as first-line monotherapy for adults with metastatic NSCLC whose tumors are EGFR and ALK wild-type but have high PD-L1 expression (PD-L1 stained ≥50% of tumor cells or PD-L1 stained tumor-infiltrating immune cells covering ≥10% of the tumor area).

The FDA also approved the VENTANA PD-L1 (SP142) Assay as a companion diagnostic to identify patients with NSCLC who are eligible for treatment with atezolizumab.

The drug was evaluated in the IMpower110 trial (NCT02409342), which enrolled patients with stage IV, PD-L1–positive (tumor cells [TC] ≥1% or immune cells [IC] ≥1%) NSCLC who had received no prior chemotherapy for metastatic disease.

The patients were randomized to receive atezolizumab at 1,200 mg every 3 weeks (n = 286) or platinum-based chemotherapy (n = 263), which consisted of carboplatin or cisplatin with either pemetrexed or gemcitabine, until disease progression or unacceptable toxicity.

Overall survival was superior in the atezolizumab arm, but only among patients with high PD-L1 expression (TC ≥50% or IC ≥10%). The median overall survival was 20.2 months among PD-L1–high patients in the atezolizumab arm and 13.1 months among PD-L1–high patients in the chemotherapy arm (hazard ratio, 0.59; P = .0106). There was no significant difference in overall survival between the treatment arms for patients in the other two PD-L1 subgroups – TC ≥5% or IC ≥5% and TC ≥1% or IC ≥1%.

Serious adverse events occurred in 28% of patients receiving atezolizumab. The most frequent of these were pneumonia (2.8%), chronic obstructive pulmonary disease (2.1%), and pneumonitis (2.1%). Fatal adverse events in the atezolizumab arm included unexplained death, aspiration, chronic obstructive pulmonary disease, pulmonary embolism, acute myocardial infarction, cardiac arrest, mechanical ileus, sepsis, cerebral infraction, and device occlusion (one patient each).

The FDA has granted the approval of atezolizumab to Genentech and the approval of the VENTANA PD-L1 (SP142) Assay to Ventana Medical Systems.

A completely new approach to the treatment of prostate cancer is now available to clinicians through the approval of the first PARP inhibitor for use in certain patients with this disease.

Rucaparib (Rubraca, Clovis Oncology) is the first PARP inhibitor approved for use in patients with metastatic castration-resistant prostate cancer (mCRPC) that harbors deleterious BRCA mutations (germline and/or somatic). The drug is indicated for use in patients who have already been treated with androgen receptor–directed therapy and a taxane-based chemotherapy.

The drug is already marketed for use in ovarian cancer.

The new prostate cancer indication was granted an accelerated approval by the US Food and Drug Administration (FDA) on the basis of response rates and effect on levels of prostate-specific antigen (PSA) from the TRITON2 clinical trial. A confirmatory phase 3 trial, TRITON3, is currently underway.

“Standard treatment options for men with mCRPC have been limited to androgen receptor–targeting therapies, taxane chemotherapy, radium-223, and sipuleucel-T,” said Wassim Abida, MD, a medical oncologist at Memorial Sloan Kettering Cancer Center in New York City, in a statement.

“Rucaparib is the first in a class of drugs to become newly available to patients with mCRPC who harbor a deleterious BRCA mutation,” said Abida, who is also the principal investigator of the TRITON2 study. “Given the level and duration of responses observed with rucaparib in men with mCRPC and these mutations, it represents an important and timely new treatment option for this patient population.”
 

Other indications, another PARP inhibitor

Rucaparib is already approved for the treatment of women with advanced BRCA mutation–positive ovarian cancer who have received two or more prior chemotherapies. It is also approved as maintenance treatment for patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who demonstrate a complete or partial response to platinum-based chemotherapy, regardless of BRCA status.

Another PARP inhibitor, olaparib (Lynparza, AstraZeneca), is awaiting approval for use in prostate cancer in men with BRCA mutations. That pending approval is based on results from the phase 3 PROfound trial, which was hailed as a “landmark trial” when it was presented last year. The results showed a significant improved in disease-free progression. The company recently announced that there was also a significant improvement in overall survival.

Olaparib is already approved for the maintenance treatment of platinum-sensitive relapsed ovarian cancer regardless of BRCA status and as first-line maintenance treatment in BRCA-mutated advanced ovarian cancer following response to platinum-based chemotherapy. It is also approved for germline BRCA-mutated HER2-negative metastatic breast cancer previously treated with chemotherapy and for the maintenance treatment of germline BRCA-mutated advanced pancreatic cancer following first-line platinum-based chemotherapy.
 

Details of the TRITON2 study

The accelerated approval for use of rucaparib in BRCA prostate cancer was based on efficacy data from the multicenter, single-arm TRITON2 clinical trial. The cohort included 62 patients with a BRCA (germline and/or somatic) mutation and measurable disease; 115 patients with a BRCA (germline and/or somatic) mutation and measurable or nonmeasurable disease; and 209 patients with homologous recombination deficiency (HRD)–positive mCRPC.

The major efficacy outcomes were objective response rate (ORR) and duration of response. Confirmed PSA response rate was also a prespecified endpoint. Data were assessed by independent radiologic review.

For the patients with measurable disease and a BRCA mutation, the ORR was 44%. The ORR was similar for patients with a germline BRCA mutation.

Median duration of response was not evaluable at data cutoff but ranged from 1.7 to 24+ months. Of the 27 patients with a confirmed objective response, 15 (56%) patients showed a response that lasted 6 months or longer.

In an analysis of 115 patients with a deleterious BRCA mutation (germline and/or somatic) and measurable or nonmeasurable disease, the confirmed PSA response rate was 55%.

The safety evaluation was based on an analysis of the 209 patients with HRD-positive mCRPC and included 115 with deleterious BRCA mutations. The most common adverse events (≥20%; grade 1-4) in the patients with BRCA mutations were fatigue/asthenia (62%), nausea (52%), anemia (43%), AST/ALT elevation (33%), decreased appetite (28%), rash (27%), constipation (27%), thrombocytopenia (25%), vomiting (22%), and diarrhea (20%).

Rucaparib has been associated with hematologic toxicity, including myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). However, MDS/AML was not observed in the TRITON2 study, regardless of HRD mutation.
 

Confirmation with TRITON3

A phase 3, randomized, open-label study, TRITON3, is currently underway and is expected to serve as the confirmatory study for the accelerated approval in mCRPC. TRITON3 is comparing rucaparib with physician’s choice of therapy in patients with mCRPC who have specific gene alterations, including BRCA and ATM alterations, and who have experienced disease progression after androgen receptor–directed therapy but have not yet received chemotherapy. The primary endpoint for TRITON3 is radiographic progression-free survival.

The U.S. Food and Drug Administration approved ripretinib (Qinlock, Deciphera Pharmaceuticals) tablets as the first-ever drug specifically approved as a fourth-line treatment for advanced gastrointestinal stromal tumors (GISTs).

A new kinase inhibitor, ripretinib is indicated for patients previously treated with three or more other kinase inhibitor therapies, including imatinib.

“Despite the progress that has been made over the past 20 years in developing treatments for GIST … some patients don’t respond to treatment and their tumors continue to progress. Today’s approval provides a new treatment option for patients who have exhausted all FDA-approved therapies for GIST,” said Richard Pazdur, MD, acting director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research.

Dr. Pazdur explained that the FDA has previously approved four targeted therapies for GISTs – imatinib in 2002, sunitinib in 2006, regorafenib in 2013, and avapritinib in 2020.

The new approval of ripretinib is based on the results of a multicenter, randomized, double-blind, placebo-controlled clinical trial that enrolled 129 patients with advanced GISTs whose disease progressed despite prior treatment with the other targeted therapies.

In the trial, patients received ripretinib or placebo once a day in 28-day cycles, until disease progression, or intolerable toxicity.

Median progression-free survival was 6.3 months in the ripretinib arm versus 1 month in the placebo arm.

The most common side effects with ripretinib were alopecia, fatigue, nausea, abdominal pain, constipation, myalgia, diarrhea, decreased appetite, palmar-plantar erythrodysesthesia syndrome, and vomiting.

Ripretinib also can cause skin cancer, hypertension, and cardiac dysfunction manifested as ejection fraction decrease.

The FDA collaborated with the Australian Therapeutic Goods Administration and Health Canada on the review of this application as part of Project Orbis.

The US Food and Drug Administration (FDA) today approved the combination of nivolumab (Opdivo, Bristol-Myers Squibb) plus ipilimumab (Yervoy, Bristol-Myers Squibb) as first-line treatment for patients with metastatic non–small cell lung cancer (NSCLC) whose tumors express PD-L1 (≥1%).

Use is limited to patients with no epidermal growth factor receptor or anaplastic lymphoma kinase genomic tumor aberrations.

The FDA also approved a companion diagnostic device, the PD-L1 IHC 28-8 pharmDx (Agilent Technologies), for identifying patients appropriate for the combination treatment.

The approval is based on results from the CHECKMATE-227 study, a randomized, open-label, multipart trial in patients with metastatic or recurrent NSCLC and no prior anticancer therapy.

The findings were first presented at the 2019 European Society of Medical Oncology (ESMO 2019) annual meeting, and simultaneously published online in the New England Journal of Medicine.

In part 1a of the trial, 793 patients were randomly assigned to receive either the combination of nivolumab plus ipilimumab (n = 396) or platinum-doublet chemotherapy (n = 397). Median overall survival was 17.1 months versus 14.9 (hazard ratio, 0.79; 95% confidence interval, 0.67, 0.94; P = .006). Confirmed overall response rate was 36% and 30%.

Median response duration was 23.2 months in the nivolumab-plus-ipilimumab group versus 6.2 months in the platinum-doublet-chemotherapy group.

The most common adverse reactions in 20% or more of patients receiving the combination of nivolumab plus ipilimumab in CHECKMATE-227 were fatigue, rash, decreased appetite, musculoskeletal pain, diarrhea/colitis, dyspnea, cough, pruritus, nausea, and hepatitis.

At ESMO 2019, study investigator Solange Peters, MD, PhD, Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland, called the results “practice changing.”

But Marina C. Garassino, MD, head of thoracic medical oncology at the National Cancer Institute of Milan, Italy, had a different opinion. She said that although the results “show we have a new treatment option for the first-line treatment of metastatic NSCLC ... we don’t yet know if the findings are practice changing.”

Garassino added that more work is needed to determine which patients are optimally treated with two immunotherapies, with a combination of chemotherapy and immunotherapy, or just with a single agent.

The recommended doses for metastatic NSCLC are nivolumab 3 mg/kg every 2 weeks and ipilimumab 1 mg/kg every 6 weeks until disease progression or unacceptable toxicity, or up to 2 years in patients without disease progression.

More information about the approval is available on the FDA website.

The Food and Drug Administration has granted accelerated approval to pomalidomide (Pomalyst, Bristol-Myers Squibb) for the treatment of AIDS-related Kaposi sarcoma that is resistant to highly active antiretroviral therapy (HAART) or that occurs in HIV-negative patients.

Pomalidomide is the only oral agent and first new treatment option for Kaposi sarcoma in more than 20 years, according to the company.

The drug, a thalidomide analogue, is already marketed for the treatment of multiple myeloma.

Pomalidomide has “shown positive results in Kaposi sarcoma patients, regardless of their HIV status,” said Robert Yarchoan, MD, chief of the HIV and AIDS Malignancy Branch, National Cancer Institute, in a press statement.

The conditional approval is based on the 71% overall response rate observed in a phase 1/2 open-label, single-arm clinical trial that involved 28 patients, 18 of whom were HIV positive and 10 of whom were HIV negative.

Most of the responses were partial (57%; 16/28); 14% (4/28) were complete. Median duration of response was 12.1 months. Additionally, for half of the patients who showed a response, that response was maintained for more than 12 months.

Patients received 5 mg of pomalidomide once daily for 21 of 28-day cycles until disease progression or unacceptable toxicity occurred.

Permanent discontinuation because of an adverse reaction occurred in 11% (3/28) of patients.

Adverse reactions (≥20%) included maculopapular rash (71%), constipation (71%), fatigue (68%), nausea (36%), diarrhea (32%), cough (29%), dyspnea (29%), peripheral edema (29%), upper respiratory tract infection (29%), muscle spasms (25%), hypothyroidism (21%), dry skin (21%), and chills (21%).

Grade 3 or 4 adverse reactions included maculopapular rash (3.6%), diarrhea (3.6%), and peripheral edema (3.6%).

Grade 3 or 4 laboratory abnormalities (≥5%) that worsened from baseline included decreased absolute neutrophil count (50%), decreased phosphate level (25%), elevated glucose level (7%), and elevated creatine kinase level (7%).

As a thalidomide analogue, pomalidomide includes a boxed warning in the prescribing information; thalidomide is a known human teratogen that causes severe birth defects or embryo-fetal death. Deep vein thrombosis, pulmonary embolism, myocardial infarction, and stroke can occur in patients treated with pomalidomide; thromboprophylaxis is recommended.

Pomalidomide is available only through a restricted distribution program, Pomalyst REMS.

The Food and Drug Administration has announced a new approved indication for olaparib (Lynparza) in adults with advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer.

Olaparib is now FDA-approved for use in combination with bevacizumab as maintenance therapy in patients who responded to first-line platinum-based chemotherapy and whose cancer is homologous recombination deficiency positive, as defined by a deleterious or suspected deleterious BRCA mutation and/or genomic instability.

The FDA also approved the Myriad myChoice CDx test as a companion diagnostic for olaparib.

Trial results

The efficacy of olaparib and the myChoice CDx test were assessed in patients in the phase 3 PAOLA-1 trial (NCT02477644). The study enrolled patients with advanced high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer who had received first-line platinum-based chemotherapy and bevacizumab.

Patients were stratified by first-line treatment outcome and BRCA mutation status, as determined by prospective local testing. All available clinical samples were retrospectively tested with the Myriad myChoice CDx test.

The patients were randomized to receive olaparib at 300 mg orally twice daily in combination with bevacizumab at 15 mg/kg every 3 weeks (n = 537) or placebo plus bevacizumab (n = 269). Patients continued bevacizumab in the maintenance setting and started olaparib 3-9 weeks after their last chemotherapy dose. Olaparib could be continued for up to 2 years or until disease progression or unacceptable toxicity.

The median progression-free survival among the 387 patients with homologous recombination deficiency-positive tumors was 37.2 months in the olaparib arm and 17.7 months in the placebo arm (hazard ratio, 0.33), according to the prescribing information for olaparib.

Serious adverse events occurred in 31% of patients in the olaparib arm. The most common were hypertension (19%) and anemia (17%).

Dose interruptions from adverse events occurred in 54% of patients in the olaparib arm, and dose reductions from adverse events occurred in 41%.

The Food and Drug Administration has approved leuprolide acetate (Fensolvi) for treating children aged 2 years and older with central precocious puberty.

Wikimedia Commons/FitzColinGerald/ Creative Commons License

Approval was based on results from a multicenter, open-label, single-arm, phase 3 study of 64 children with central precocious puberty, a rare disease described as onset of puberty before age 8 years in girls and before age 9 in boys. The primary study endpoint was achieved, with 87% of children achieving a serum luteinizing-hormone concentration of less than 4 IU/L within 6 months post injection. Sex hormones were suppressed to prepubertal levels, and clinical signs of puberty were halted or reversed.

Adverse events during the study were mostly mild or moderate; none led to withdrawal from the study. The most common adverse events reported were injection-site pain (31%), nasopharyngitis (22%), and fever (17%).

“Children with CPP require treatment for several years and missing treatment or stopping treatment too soon may lead to significant short stature and misalignment between chronological age and physical and emotional development. Fensolvi offers treating physicians and their patients with CPP a safe and effective treatment option that is administered twice a year with a small injection volume that has the potential to improve compliance,” Karen Klein, MD, of Rady Children’s Hospital in San Diego, said in the press release.
